Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report CHAPTER 1 INTRODUCTION TO THE ENVIRONMENTAL REPORT This Environmental Report (ER) is prepared and submitted as part of the Tennessee Valley Authority (TVA) application for an Early Site Permit (ESP) under Title 10 of the Code of Federal Regulations (10 CFR) Part 52 for the Clinch River Nuclear (CRN) Site in Oak Ridge, Roane County, Tennessee. The ESP would represent U.S. Nuclear Regulatory Commission (NRC) approval of the CRN site for new nuclear power units demonstrating small modular reactor (SMR) technology. This is separate from the filing of a combined license application (COLA) for such a facility. The site location is shown in Figure 1.1-1. In accordance with NRC regulations, TVA has prepared this ER to analyze the environmental effects of construction, operation, and decommissioning of two or more SMRs at the CRN Site. The NRC uses this ER to develop an Environmental Impact Statement to meet the requirements of the National Environmental Policy Act (NEPA) for federal agencies to consider the environmental effects of their action (e.g.,
issuance of an ESP).
1.1    THE PROPOSED ACTION The proposed federal action is the NRC issuance, under the provisions of 10 CFR Part 52, of an ESP to TVA approving the CRN Site as a suitable site for future demonstration of the construction and operation of two or more SMRs. In this ESP application (ESPA), TVA identifies a proposed site suitable for deployment of two or more SMRs. The SMR technology is designed with inherent enhanced safety and security features. SMR deployment will demonstrate that the technology is capable of incrementally supplying clean, secure, reliable power that is less vulnerable to disruption to facilities owned by federal agencies (e.g., U.S. Department of Energy (DOE), U.S. Department of Defense (DoD), TVA, etc.).
This ER provides an analysis of the effects on the environment from site preparation, construction, operation, and decommissioning of two or more SMRs at the CRN Site. The proposed action does not include any decision or approval to build the facility. As TVA is not requesting limited work authorization as part of this ESPA, an NRC-issued combined license (COL) is required prior to initiation of construction.
1.1.1  Purpose and Need The purpose and need for the NRC proposed action, issuance of the ESP, is to provide for early resolution of site safety and environmental issues, which provides stability in the licensing process.
TVA proposes to deploy two or more SMRs with a maximum total electrical output of 800 megawatt electric (MWe) for the site, to demonstrate the capability of SMR technology. SMRs provide the benefits of nuclear-generated power in situations where large nuclear units, with an approximate electrical output exceeding 1000 MWe, are not practical, because of transmission system constraints, limited space or water availability, or constraints on the availability of capital for construction and operation.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report In 2009, Executive Order (EO) 13514 was issued on Federal Leadership in Environmental, Energy, and Economic Performance. EO 13514 directed all Federal Agencies to reduce their greenhouse gas (GHG) emissions by 28% by 2020 (Reference 1-1). This was followed by EO 13693 (March 2015), Planning for Federal Sustainability in the Next Decade (Reference 1-2),
which called for further reduction of Federal facility GHG emissions to 40 percent by 2025, and identified SMRs as one of the alternative energy options for meeting clean energy goals.
In 2013, Executive Order (EO) 13636 was issued on Improving Critical Infrastructure Cybersecurity and Presidential Policy Directive (PPD) 21 on Critical Infrastructure Security and Resilience (Reference 1-3). EO 13636 and PPD-21 are designed to strengthen the security and resilience of critical infrastructure against evolving threats and hazards.
TVA and DOE, based on a Memorandum of Understanding, began working together to explore various options under which TVA could license, construct, operate, and maintain two or more SMR units (Reference 1-4).
By letter dated February 17, 2016, DOE expressed its support to TVA for the development and licensing of SMRs as a means to meet DOE goals of improving the environmental, economic, and energy security outlook for the United States (Reference 1-5). DOE believes that SMR deployment near federal facilities could provide enhanced reliability and other benefits, by providing continued operation during a widespread and extended loss of the electrical power grid, meeting reliability needs with clean energy that supports carbon reduction directives. DOE specifically requested TVA to assess, as a part of the deployment project planning and licensing process, the ability of SMRs to continue to supply electricity to nearby offsite customers during a disruption to offsite power supplies. This includes electricity transmission to those customers in a manner less vulnerable to intentional destructive acts and natural phenomena that could disrupt the power supply.
The main objectives of the Clinch River (CR) SMR Project are to demonstrate that:
* Power generated by SMRs could be used for addressing critical energy security issues.
Their use on or immediately adjacent to DoD or DOE facilities, using robust transmission (e.g., armored transformers, underground transmission), could address national security needs by providing reliable electric power in the event of a major grid disruption. A more reliable electric power supply could be accomplished by the SMR operation in power island mode with robust transmission to critical facilities. In addition, intentional destructive acts (e.g., terrorist attacks) and natural phenomena (e.g., tornadoes, floods, etc.) could disrupt the grid and the ability to restore most generation sources. SMRs can provide reliable energy for extended operation. Because nuclear reactors require fuel replenishment less frequently than other power generation sources (coal, gas, wind and solar), SMRs are less vulnerable to interruptions of fuel supply and delivery systems. TVA could demonstrate this power islanding and secure supply concept as part of the CR SMR project by utilizing controls, switching, and transmission capabilities to disconnect the SMR power plant from the electrical grid while maintaining power from the SMR power plant to a specified DOE 1-2                                    Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report power need. Such a demonstration would show that SMR technology is capable of supplying reliable power that is less vulnerable to disruption from intentional destructive acts and natural phenomena.
* SMR technology can assist federal facilities with meeting carbon reduction objectives.
Energy-related carbon dioxide (CO2) emissions account for more than 80 percent of GHG emissions in the United States (Reference 1-6). Studies show that on average coal combustion generates approximately 894-975 grams of CO2 per kilowatt-hour (g/kWh) of electricity generated. Natural gas generates an estimated 450-519 g/kWh. Nuclear power emission rates have been calculated to range from 6 - 26 g/kWh. (Reference 1-7)
* SMR design features include underground containment and inherent safe-shutdown features, longer station blackout coping time without external intervention, and core and spent fuel pool cooling without the need for active heat removal. These key features advance safety by eliminating several design basis accident scenarios. Development of a security-informed design efficiently provides the same or better protection against the threats large reactors must consider. Physical security is designed into the SMR plant architecture, incorporating lessons learned from significant shifts in security posture since 2001, and the opportunity to build more inherently secure features into the initial design.
* SMR power generating facilities are designed to be deployed in an incremental fashion to meet the power generation needs of a service area. Generating capacity can be added in increments to match load growth projections. For the CR SMR project, two or more SMRs would be constructed and brought into operation incrementally to achieve up to 800 MWe.
1.1.2  Proposed Project This subsection provides a brief description of the proposed project, the applicant and owner, the site location, the selected reactor types and other plant design features, preapplication public participation activities, and major project activity dates.
1.1.2.1    The Applicant and Owner TVA is the applicant and owner and sole point of contact with the NRC in all matters related to this ESPA. TVA is a corporate agency of the United States that provides electricity for business customers and local power distributors serving 9 million people in parts of seven southeastern states. As authorized by the Tennessee Valley Authority Act, TVA is committed to maintaining a national leadership role in technological innovation (Reference 1-8). Innovation is a part of the agency's mission as set forth by the TVA Act, and an important element of its mission to be a leader in the generation of affordable, clean power and a conservator of the Tennessee Valley's precious natural resources. Compared to a large nuclear plant, small modular reactors offer advantages in enhanced safety, less construction time and reduced expenditures. TVA's work on a deployment of this technology demonstrates its leadership in a movement toward cleaner, lower-cost, and more reliable electricity for our customers.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 1.1.2.2    Site Location The CRN Site is located on the northern bank of the Clinch River arm of the Watts Bar Reservoir in Oak Ridge, Roane County, Tennessee from approximately Clinch River Mile (CRM) 19 to approximately CRM 14.5 (Reference 1-9). The CRN Site is approximately 7 miles (mi) east of Kingston, Tennessee and approximately 25 mi west-southwest of Knoxville, Tennessee. Figure 1.1-1 shows the location of the CRN Site. Additional information regarding the CRN Site location is provided in Section 2.1, Site Location.
1.1.2.3    Reactor Information This ESPA is intended to demonstrate the suitability of the CRN Site for the deployment of two or more SMRs to demonstrate the capability of SMR technology. TVA has not yet selected a specific SMR technology. However, the design characteristics of four SMR designs under consideration were used to develop a plant parameter envelope (PPE) to describe the proposed plant. Additional information regarding the description of the PPE is provided in Section 3.1, External Appearance and Plant Layout. An SMR is a nuclear power generating unit with an electrical output of no more than 300 MWe, which is considerably less than the electrical output of approximately 1000 MWe provided by a typical commercial reactor in the United States.
SMRs are manufactured in factories as large, fabricated components and shipped to the facility site. Therefore, less onsite construction is required for installation of SMRs than for installation of a typical commercial reactor. SMRs may provide the benefits of nuclear-generated power in situations where large nuclear units are not practical because of transmission system constraints, limited space or water availability, or limited available capital for construction and operation. Additional information regarding SMRs is provided in Section 3.2, Reactor Power Conversion System.
1.1.2.4    Cooling System Information The SMRs being considered for deployment at the CRN Site use a recirculating (closed-cycle) cooling water system. Mechanical draft cooling towers are most suitable for use at the CRN Site. A new shoreline intake structure would supply makeup water from the Clinch River arm of the Watts Bar Reservoir to the facility. A new discharge structure located downstream of the intake structure would convey cooling tower blowdown and other planned discharges to the Clinch River arm of the Watts Bar Reservoir. Additional information regarding the cooling system is provided in Section 3.4, Cooling System.
1.1.2.5    Transmission System Information The CRN Site would be served by a new 500-kilovolt (kV) switchyard. The Watts Bar NP-Bull Run FP 500 kV line is to be looped in with approximately 0.7 mi of double circuit transmission line. In addition, a new 161-kV switchyard may be constructed for auxiliary station service and looped in to the Kingston FP-Fort Loudoun HP#1 161-kV transmission line with approximately 0.2 mi of double circuit transmission line. Additional transmission system upgrades would be 1-4                                    Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report required to support the added generation capacity to the system. A portion of the Kingston FP -
Fort Loudoun HP #1 161-kV transmission line is to be relocated within the CRN Site.
A new 69-kV underground transmission line (approximately 5 mi) could be constructed to connect the CRN Site switchyard via 500 kV to 69 kV transformers to the Bethel Valley Substation. This 69-kV transmission line would follow the existing Watts Bar NP - Bull Run FP 500-kV transmission line corridor on DOE property.
Additional information regarding the transmission system is provided in Section 3.7, Power Transmission System.
1.1.2.6    Preapplication Public Involvement The possibility of deployment of SMRs at the CRN Site and SMR development in general has been publicized widely in the local and national press, trade journals, electronic media, and professional conferences. NRC and TVA have participated in numerous preapplication public meetings at NRC headquarters in Rockville, Maryland. These meetings have occurred since 2010 and covered various technical topics, including regulatory framework meetings that preceded TVAs change from a construction permit application to an ESPA in 2014. At the time of submittal of the application, no public outreach meetings specifically designed to comply with NEPA requirements have been conducted.
1.1.2.7    Construction Start Date The ESP does not constitute a decision or approval to build new units. A limited work authorization application under NRC regulation 10 CFR 50.10 is not included with this ESPA.
At this time, TVA has not established a date for preconstruction activities. It is estimated that site preparation activities (preconstruction) will take between 6 and 18 months to complete.
Based on estimates provided by the reactor vendors, assuming that appropriate licenses are obtained, actual construction of the SMR units is expected to take between three and five years.
1.2      STATUS OF REVIEWS, APPROVALS AND CONSULTATIONS Numerous federal, state, regional, and local and affected Native American tribal agencies environmental protection licenses, permits, reviews, approvals, and/or consultations (collectively referred to as authorizations) are required to support the preconstruction, construction, and operation phases of the project. Tables 1.2-1 and 1.2-2 identify, for each authorization, the following information:
* Permit/authorization
* Responsible agency
* Applicable law, ordinance, or regulation 1-5                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* Principal environmental factors covered by the authorization Appropriate consultations with federal, state, and local agencies have been initiated. However, authorizations from federal, state, and local authorities for construction and operation are not yet necessary because an ESP is limited to establishing the acceptability of the CRN Site for future development. TVA plans to apply for and receive any required authorizations prior to initiating preconstruction, construction, and operational activities. The following subsections describe the activities to be authorized.
1.2.1    ESP Issuance The following statutes summarize the agency consultations necessary for the ESP. Table 1.2-1 lists ESP authorizations required prior to NRC issuance of an ESP.
Endangered Species Act: The Endangered Species Act requires federal agencies to ensure that agency action is not likely to jeopardize any species that is listed or proposed for listing as endangered or threatened. The Endangered Species Act requires consultation with the U.S.
Fish and Wildlife Service (USFWS). In addition, as a matter of policy, the NRC consults with states regarding state-protected species.
National Historic Preservation Act: The National Historic Preservation Act requires federal agencies having the authority to license any major federal action, prior to issuing the license, to take into account the effect of the undertaking on historic properties and to afford the Advisory Committee on Historic Preservation an opportunity to comment on the undertaking. Committee regulations provide for establishing an agreement with any State Historic Preservation Officer (SHPO) to substitute state review for Committee review (36 CFR 800.7). The NRC consults with the Tennessee SHPO.
Coastal Zone Management Act: The Federal Coastal Zone Management Act imposes requirements on applicants for a federal license to conduct an activity that could affect a states coastal zone. The Coastal Zone Management Act requires the applicant to certify to the licensing agency that the proposed activity is consistent with the states federally-approved coastal zone management program. Tennessee does not have any coastal barrier resource areas; therefore no action is required.
Clean Air Act: The Clean Air Act imposes regulatory requirements on federally-licensed projects where construction and operation may have an impact on state and regional air quality. The portion of Roane County in which the CRN Site is located is in attainment for all air pollutants.
The NRC consults with the Tennessee Department of Environmental Control (TDEC) Division of Air Pollution Control on nonattainment issues.
Clean Water Act/Rivers and Harbors Act: The Clean Water Act requires that federal agencies consider the potential impacts to jurisdictional waters of the United States. Section 401 of this Act regulates the issuance of a Water Quality Certification, Section 402 regulates point source and non-point source discharges under the National Pollutant Discharge Elimination System, 1-6                                    Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report and Section 404 regulates the placement of fill in waters of the United States. The U. S. Army Corps of Engineers (USACE) regulates dredge and fill activities in navigable waters pursuant to Section 10 of the Rivers and Harbors Act. As a matter of policy, the NRC consults with the USACE and TDEC regarding potential impacts to waters of the United States.
1.2.2    Preconstruction, Construction, and Operation Activities Permits and authorizations for future construction and operation of two or more SMRs are to be obtained in accordance with applicable statutes and regulations. Applications for these authorizations are to be developed after a reactor technology has been selected and detailed design is initiated. Table 1.2-2 lists authorizations that are anticipated for preconstruction, construction, and operation of two or more SMRs.
1.3      METHODOLOGY NRC regulation 10 CFR 52.17(a)(2), Contents of Applications; Technical Information, specifies the contents of an ER for an ESPA. Regulatory Guide (RG) 4.2, Preparation of Environmental Reports for Nuclear Power Stations, Revision 2, July 1976, provides guidance to applicants preparing ERs for nuclear power stations. NUREG-1555, Standard Review Plans for Environmental Reviews for Nuclear Power Plants: Environmental Standard Review Plan, provides guidance to the NRC staff when conducting environmental reviews of applications related to nuclear power plants. Attachment 3 of NRCs Office of Nuclear Reactor Regulation Review Standard (RS) -002, Processing Applications for Early Site Permits provides guidance to NRC staff when conducting environmental reviews associated with ESPs.
In preparing this ER, TVA used NUREG-1555 and RS-002 for guidance in establishing the format and content of its ER and NRC RG 4.2 for guidance on the preparation of the ER. Table 1.3-1 lists regulatory requirements and where in the ER each requirement is addressed.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report CHAPTER 2 ENVIRONMENTAL DESCRIPTION Chapter 2 describes the existing environmental conditions at the Clinch River Nuclear (CRN)
Site, vicinity, and region. The environmental descriptions provide sufficient detail to identify those environmental resources that have the potential to be affected by the construction, operation, or decommissioning of two or more Small Modular Reactors (SMRs). The level of detail is commensurate with level of information associated with an Early Site Permit Application (ESPA). This chapter is divided into eight subsections:
* Site Location (Section 2.1)
* Land (Section 2.2)
* Water (Section 2.3)
* Ecology (Section 2.4)
* Socioeconomics (Section 2.5)
* Geology (Section 2.6)
* Meteorology and Air Quality (Section 2.7)
* Noise (Section 2.8)
* Related Federal Project Activities (Section 2.9) 2.0-1                                    Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.1      SITE LOCATION The Tennessee Valley Authority (TVA) proposes to demonstrate that the approximately 935-acre (ac) Clinch River Nuclear (CRN) Site is a suitable site for the construction and operation of two or more small modular reactors (SMRs). The CRN Site is located in Roane County in eastern Tennessee. The property is owned by the federal government and is managed by TVA (Reference 2.1-1). TVA is the named applicant for the Clinch River SMR Project. The regional setting for the CRN Site is depicted in Figure 2.1-1. The CRN Site and immediate vicinity (6-mile [mi] radius) are shown in Figure 2.1-2.
The proposed site configuration, including the location of the surrogate plant as defined by the plant parameter envelope (see Subsection 3.1.2 for a description), is presented in Figure 2.1-3.
The CRN Site center point is listed in Tables 2.1-1 and 2.1-2 and shown on Figure 2.1-2. The center point of the CRN Site is located approximately 11 mi southwest of the City of Oak Ridge, Tennessee business district. The center point of the CRN Site is approximately 25 mi west-southwest of downtown Knoxville, Tennessee; 24 mi west-northwest of Maryville/Alcoa, Tennessee; and 30 mi north-northeast of Athens, Tennessee. (Reference 2.1-2; Reference 2.1-3)
The nearest population center to the CRN Site, as defined by Title 10 of the Code of Federal Regulations 100.3, is the City of Oak Ridge, Tennessee. The Site is located within the Oak Ridge city limits. The City of Oak Ridge, Tennessee is also the largest city whose boundary lines are located within 10 mi of the CRN Site. (Reference 2.1-4; Reference 2.1-3)
Although the urbanized area of Oak Ridge, Tennessee is within 10 mi north of the CRN Site, the majority of the citys incorporated area within the 10-mi radius of the CRN Site is occupied by federally-owned land, including the U.S. Department of Energys (DOEs) Oak Ridge Reservation. The next closest communities from the center point of the CRN Site are the cities of Kingston, Tennessee (7.2 mi to the west) and Lenoir City, Tennessee (approximately 8.9 mi to the southeast). Oak Ridge, Tennessee is the only urbanized area located within the CRN Site vicinity (6-mi radius). (Reference 2.1-3)
A principal arterial, Interstate 40, is located south of the CRN Site as shown in Figure 2.1-1. Two rural, principal arterials frame the CRN Site on the north as shown in Figure 2.1-2. Tennessee State Highway (TN) 58 is located northwest of the CRN Site and TN 95 is located to the northeast. The CRN Site is accessed from either of these roadways via Bear Creek Road. No known major roadway improvements are planned for the area. The City of Oak Ridge has supported several studies related to the possible development of a general aviation airport at the East Tennessee Technology Park (Reference 2.1-5). A rail spur (EnergySolutions Heritage Railroad) is located approximately 2.5 mi north-northwest of the center point of the CRN Site, northwest of TN 58 (Reference 2.1-6).
The CRN Site is located on a peninsula on the north shore of the Clinch River arm of Watts Bar Reservoir (Figure 2.1-2), between approximately Clinch River Mile (CRM) 14.5 and CRM 19.
2.1-1                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report (Reference 2.1-7; Reference 2.1-8) There is an inactive DOE barge terminal at CRM 13.1, near Bear Creek Road and the TN 58 ramp approximately 1.3 mi northwest of the primary CRN Site entrance (Reference 2.1-9). A former barge terminal that was used for construction of TN 58 is located between the TN 58 bridge and the CRN Site entrance. A barge terminal was approved to be constructed in association with the Clinch River Breeder Reactor Project (CRBRP) in the 1970s and 1980s. This terminal was proposed within the CRN Site south of the mouth of Grassy Creek but was never constructed (Reference 2.1-10; Reference 2.1-11). The Grassy Creek Habitat Protection Area is located adjacent to the northern boundary of the CRN Site as shown in Figure 2.1-2.
The majority of the CRN Site is within the 7.5 minute Elverton Quadrangle. The eastern portion of the site is in the Bethel Valley Quadrangle. The site is bracketed by the Petros and Windrock Quadrangles to the north, the Lovell Quadrangle to the east, the Lenoir City and Cave Creek Quadrangles to the south, and the Harriman Quadrangle to the west.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.2      LAND This section describes the Clinch River Nuclear (CRN) Site and land use in the vicinity and region of the CRN Site. The CRN Site is located in Roane County in eastern Tennessee (Figure 2.1-1), and is accessible by road and river. Interstate (I-) 40 connects Knoxville and Kingston, Tennessee, and its closest point to the CRN Site is approximately 0.6 miles (mi) southeast of the nearest site boundary, across the Clinch River arm of Watts Bar Reservoir (Figure 2.1-2).
Additional interstate highways in the CRN Site region include I-75, I-640, and I-140 (Figure 2.1-1). Nearby state roads include Tennessee State Highway (TN) 58, TN 95, TN 327, TN 61, TN 70, and TN 321 (Figure 2.1-2). A privately-owned rail spur (EnergySolutions Heritage Railroad) is located approximately 2.5 mi north-northwest of the center of the CRN Site, northwest of TN 58 (Reference 2.2-1). The CRN Site is accessed from TN 58 or TN 95 via Bear Creek Road (Figure 1.1-2).
2.2.1    The Site and Vicinity 2.2.1.1 The Site The center of the CRN Site is located approximately 10.7 mi southwest of the City of Oak Ridge, Tennessee, business district (Figure 1.1-1) and lies within the Oak Ridge city limits. The CRN Site center point is approximately 25.2 mi west-southwest of downtown Knoxville, Tennessee.
The Clinch River arm of the Watts Bar Reservoir surrounds the CRN Site on the south, west, and much of the eastern sides. The majority of the CRN Site is located on a peninsula on the north bank of the Clinch River arm of the Watts Bar Reservoir, located between approximately Clinch River mile (CRM) 14.5 and CRM 19 (Reference 2.2-2). The primary entrance to the CRN Site is located adjacent to the Clinch River arm of the Watts Bar Reservoir along Bear Creek Road (Figure 2.2-1). The emergency egress road for the CRN Site intersects with the Jones Island Road on the Oak Ridge Reservation (ORR). The proposed configuration for the CRN Site is provided in Figure 2.1-3.
The Clinch River Property is the approximately 1200 acres (ac) of land adjacent to the Clinch River arm of the Watts Bar Reservoir owned by the federal government and managed by the Tennessee Valley Authority (TVA). The Clinch River Property includes the CRN Site, which is approximately 935 ac, and the Grassy Creek Habitat Protection Area (HPA). The Grassy Creek HPA is located north of the CRN Site as shown in Figure 2.2-1.
TVA directs the land management activities at the Clinch River Property in accordance with the Watts Bar Land Management Plan (Reference 2.2-3). TVA manages the property and mineral rights of the Clinch River Property. There are no known mineral resources, including oil and natural gas, within or adjacent to the CRN Site that are being exploited or are of any known value. The only known resource of value located within the CRN Site is limestone (which is not currently being exploited), and TVA owns the mineral rights for the CRN Site.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Historic property uses on the CRN Site included several small farmsteads scattered across the CRN Site and the Clinch River Breeder Reactor Project (CRBRP) (Reference 2.2-5; Reference 2.2-6). Portions of the CRN Site were disturbed during the proposed CRBRP, as described in the CRN Site Land Use and Recreation Technical Report (Reference 2.2-7). The CRN Site was selected as the location for construction of a liquid metal fast breeder reactor in 1972. Site preparation for the CRBRP began in 1982 and was nearly complete in late 1983. (Reference 2.2-8) Approximately 240 ac of the current CRN Site were disturbed during site preparation for the CRBRP (Reference 2.2-9). CRBRP site preparation activities included leveling a ridge that originally reached 880 feet (ft) above mean sea level (msl) to 780 msl, excavation of the construction area, and installation of various structures and pads (Reference 2.2-8). The excavated area totaled approximately 24 ac in extent and extended to as much as 100 ft in depth (Reference 2.2-10). Approximately three million cubic yards of earth and rock were excavated during the CRBRP site preparation. Structures installed at the CRBRP site included a cement crane pad, quality control test laboratory, construction shops, concrete batch plants, and sediment ponds. An approximately 6450 foot long 8-inch (in.) water line from the U.S.
Department of Energys (DOEs) Bear Creek Filtration Plant was also installed at the CRBRP site. (Reference 2.2-8; Reference 2.2-9) The project was terminated in late 1983 and CRBRP site redress plans were developed and implemented. Measures to stabilize the CRBRP site included reseeding of grass, and planting of trees, mulching cleared areas, installation of straw bales in shallow ditches, installation of small berms of riprap in larger ditches, installation of culverts to direct water from steep slopes, and modification of the holding ponds for long-term stability (Reference 2.2-11). Portable buildings and structures were removed from the CRBRP site with the exception of the crane pad and meteorological tower (Reference 2.2-12). The approximately 6450 foot long 8-in. water line was terminated at a hydrant and left in place (Reference 2.2-13). The 80 foot by 80 foot crane pad was left in place (Reference 2.2-9; Reference 2.2-7) The excavated area was partially backfilled in a manner to sustain site drainage. Rock bolts within the excavated area were left in place. Level areas of the CRBRP site were graded and compacted. (Reference 2.2-14) The meteorological tower was removed by TVA in October 2013 (Reference 2.2-7).
The current Clinch River Property topography includes steep hills and flat meadows as shown in Figure 2.2-1. A series of roughly parallel ridges of gradually lower elevations stretches from the Chestnut Ridge, near the CRN Site entrance and in the Grassy Creek HPA, to approximately the center of the peninsula. The ridges within the CRN Site footprint are approximately 860 to 940 msl in elevation. Several small drainages descend from these ridges to the Clinch River arm of the Watts Bar Reservoir. The southeastern portion of the peninsula is a relatively flat plateau, with an elevation of approximately 780 msl. The plateau was created during the construction activities associated with the CRBRP. A few small hills are located in this portion of the CRN Site. The large depression from previous excavation work conducted as part of the former CRBRP is also located in this area. The northeastern portion of the CRN Site consists of interspersed rolling hills and meadows. Elevations in this part of the CRN Site range from approximately 780 msl at the meadows to 940 msl at the peaks of the hills. (Reference 2.2-7) 2.2-2                                      Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report The CRN Site currently consists primarily of undeveloped land. Based on the U.S. Geological Survey (USGS) land-cover classification standards and the 2011 National Land Cover Database (NLCD), land use and land cover on ORR Site 3 is categorized and shown in Table 2.2-1 and Figure 2.2-2. Forested land (deciduous, evergreen, and mixed forest) accounts for approximately 48 percent of the CRN Site. Wetlands (emergent herbaceous and woody wetlands) occupy approximately 9 percent of the CRN Site. Other vegetated undeveloped land (grassland/herbaceous and shrub/scrub) occupies approximately 5 percent of the CRN Site.
Land classified as cultivated crops and pasture/hay occupy approximately 27 percent of the CRN Site. Open water and barren land occupy approximately 4 percent of the CRN Site.
Developed areas (high, medium, and low intensity, or open space) occupy approximately 7 percent of the CRN Site.
Modern soil survey data produced by the U.S. Department of Agriculture (USDA) in which prime farmland soils are classified are not available for the CRN Site or the adjacent ORR. A 1942 Soil Survey for Roane County includes the CRN Site and ORR. The 1942 Roane County soil survey provides soil productivity classifications based on soil suitability for various uses including cropland, pasture, and forest. Figure 2.2-3 shows the soil types on and around the CRN Site.
The area previously impacted by the CRBRP excavations is shown on Figure 2.2-3. These soils have been disturbed. Table 2.2-2 lists the 1942 soil type classifications on the CRN Site and the ORR. Table 2.2-3 lists the 2009 soil types on non-federal lands in the area.
The modern prime farmland classification of soils should be similar to the first-class (good to excellent cropland) 1942 classification. There are no first-class soils within the CRN Site or in the immediate vicinity on the ORR. The only project activities using soils currently planned for the areas included in the 2009 soil survey would be the use of borrow pits for onsite fill, which are discussed in Subsection 2.2.3.
A Farmland Conversion Impact Rating (Form AD-1006) was completed by TVA in consultation with the USDAs Natural Resources Conservation Service to quantify the potential impacts to prime farmland. The impact rating considers the acreage of prime farmland to be converted, the relative abundance of prime farmland in the surrounding county, and other criteria such as distance from urban support services and built-up areas, potential effects of conversion on the local agricultural economy, and compatibility with existing agricultural use. Sites with a total score of at least 160 have the potential to adversely affect prime farmland. The impact rating score for the CRN Site was 102 points (Environmental Report Appendix A).
Limited infrastructure development and structures are present on the CRN Site. Near the center of the peninsula on the plateau, TVA has installed a gravel parking lot and several mobile trailers and support structures, for use as office and storage space. The Hensley Cemetery, a small private cemetery, is located on the south side of the peninsula along River Road (Figure 2.2-1). TVA currently does and would continue to maintain this cemetery. Family access to this cemetery is allowed and would continue to be allowed in the future. As described in Subsection 2.2.2, two power transmission lines cross the CRN Site (Reference 2.2-7).
2.2-3                                      Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Potable water for the CRN Site is provided by the City of Oak Ridge, Tennessee, Public Works Department. Wastewater from the site is treated by the City of Oak Ridge. Solid waste is managed by TVAs solid waste disposal vendor.
As manager of federal lands around TVA reservoirs, TVA establishes land use zones within reservoir management plans. The CRN Site zones were established under the policies set forth in the 2009 Watts Bar Reservoir Land Management Plan and the 2011 TVA Natural Resource Plan. The majority of the CRN Site is designated as Zone 2 - Project Operations. A strip along the reservoir shoreline is designated Zone 3 - Sensitive Resource Management. The Grassy Creek HPA (adjacent to the CRN Site) is designated Zone 3 - Sensitive Resource Management/Natural Area. (Reference 2.2-3)
The Federal Emergency Management Agency (FEMA) develops Flood Insurance Rate Maps to determine which areas are Special Flood Hazard Areas subject to inundation by the 1 percent annual chance flood. FEMA defines the 1 percent annual chance flood (100-yr flood), also known as the base flood, as the flood which has a 1 percent chance of being equaled or exceeded in any given year. FEMA also maps areas of minimal flood hazard as those potentially subject to the 0.2 percent annual chance flood (500-yr flood). The majority of the CRN Site lies outside both the 1-percent annual flood and 0.2 percent annual flood zones (Figure 2.2-9). Portions of the Barge/Traffic area (on the south site of Bear Creek Road) lie within both the 1-percent and 0.2-percent annual flood zones. Flooding potential exists in the immediate vicinity of the CRN Site along the banks of the Clinch River arm of Watts Bar Reservoir at elevations up to 752 ft. (Reference 2.2-30; Reference 2.2-31) 2.2.1.2 The Site Vicinity The CRN Site is located entirely within Roane County. The northwestern portion of Loudon County and part of the southwestern portion of Anderson County are included within the CRN Site vicinity, defined as a 6-mi radius from the center of the CRN Site (Figure 2.1-2).
The vicinity of the CRN Site is primarily rural, consisting of forest and pasture/hay (Figure 2.2-4).
Based on the USGS land-cover classification standards and the 2011 NLCD, land use and land cover in the CRN Site vicinity is categorized and shown in Table 2.2-1 and Figure 2.2-4.
Forested land (deciduous, evergreen, or mixed forest) accounts for approximately 54 percent of the CRN Site vicinity. Wetlands (emergent herbaceous or woody wetlands) occupy approximately 3 percent of the CRN Site vicinity. Other vegetated undeveloped land (grassland/herbaceous or shrub/scrub) totals approximately 5 percent of the CRN Site vicinity.
Land classified as cultivated crops and pasture/hay total approximately 20 percent of the CRN Site vicinity. Open water or barren land occupy approximately 4 percent of the CRN Site vicinity.
The remaining approximately 14 percent of the CRN Site vicinity is classified as developed (high, medium, or low intensity, or open space).
Approximately 18,000 ac or 7.5 percent soils in the surveyed portions of Roane County could be considered prime farmland (Reference 2.2-15). According to the Watts Bar Reservoir Land 2.2-4                                    Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Management Plan, which describes existing land use for TVA-managed land on Watts Bar Reservoir, including the CRN Site, there are approximately 2900 ac of prime farmland located on reservoir lands (Reference 2.2-3).
Several commercial/industrial properties are located on north of the CRN Site along Bear Creek Road in the Clinch River Industrial Park, as depicted in Figure 2.1-2. A portion of these properties are located on TVA land designated Zone 5 - Industrial. The 161-kilovolt (kV) transmission line exits the CRN Site near the entrance gate and connects with a power substation located just outside the gate (Figure 2.2-1) (Reference 2.2-7).
The CRN Site is bounded on the northeastern side by the ORR (Reference 2.2-7). Land within the ORR is used for multiple purposes. Much of the ORR is undeveloped and consists of forested areas, grasslands and old agricultural fields, bottomlands and wetlands, utility corridors, and ridges in which a number of caves are present (Reference 2.2-16). The National Environmental Research Park and the Oak Ridge State Wildlife Management Area are both located within the ORR. These areas include wildlife management and habitat management plans. (Reference 2.2-16) Facilities within the ORR currently include the Oak Ridge National Laboratory (ORNL), the Y-12 National Security Complex, and the East Tennessee Technology Park (ETTP; Figure 2.1-2). Land uses surrounding the facilities include safety, security, and emergency planning zones; research and education areas; cleanup and remediation sites; environmental regulatory monitoring areas; wildlife management; biosolids land application; protection of cultural and historic resources; wildland fire prevention; land stewardship activities; restoration infrastructure; and public areas. The ORR 10-year (yr) site plan for land use management across the reservation was published in 2007. The 10-yr plan indicates that ORR will, in most cases, expand and build on current land uses. The 10-yr site plan includes the results of a 2002 land use planning focus group report. (Reference 2.2-17; Reference 2.2-18) In 2002, ORR identified potential surplus land in the northwest portion of the reservation (including areas northwest of the Clinch River Industrial Park and surrounding the ETTP). A focus group reviewed the land use planning associated with this potential surplus land, the public and stakeholders participated in the process. The focus group concluded with three recommendations related to ORR land use planning. The first recommendation was for the preservation of areas designated for green space/conservation within the potential surplus land area. The second recommendation was to expand the land use planning process for the remainder of the ORR. The third recommendation called for the use of a biodiversity analysis in addition to the socioeconomic impact analysis that was conducted. (Reference 2.2-19)
The south bank of the Clinch River arm of the Watts Bar Reservoir, from the Melton Hill Dam upstream of the CRN Site to beyond TN 58 downstream of the CRN Site, is largely residential with some small private pastures and farm fields. Many residences include several acres of property. The area is sparsely wooded. (Reference 2.2-7)
The Roane Regional Business and Technology Park is located approximately one-half mile east of the CRN Site, on Industrial Park Road, adjacent to I-40. This business park occupies approximately 655 ac and has several operating facilities and vacant space. Current tenants 2.2-5                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report include food distribution, tool, engineering, ceramics, roofing, energy, engine parts, and automotive companies. The industrial park also contains sites available for development.
(Reference 2.2-20)
Several recreational areas are located in the immediate CRN Site vicinity. These include Melton Hill Dam Recreation Area, the Soaring Eagle Campground and RV Park, the Gallaher Recreation Area, the ORR which is a Tennessee Wildlife Management Area, the ETTP Visitors Overlook, the Southern Appalachia Railway Museum, the Wheat Community African Burial Ground, several hiking trails and greenways, and boating and fishing activities on the Clinch River arm of Watts Bar Reservoir and Melton Hill Reservoir (Figure 2.1-2). (Reference 2.2-7)
Recreational land use is discussed in detail in Subsection 2.5.2.5 Aesthetics and Recreation.
The CRN Site is located within the city limits of Oak Ridge, Tennessee, making Oak Ridge the closest city in the vicinity of the CRN Site. The City of Oak Ridge has an extensive zoning ordinance and plan. However, although the CRN Site is within the city limits, Oak Ridge zoning ordinances do not apply to federal property.
No operating airports or ports are located within the 6-mi CRN Site vicinity.
2.2.2    The Region The CRN Site region is defined as the area within a 50 mi radius of the center of the CRN Site (Figure 2.1-1). There are 33 counties at least partially within 50-mi of the center point of the CRN Site. Three of these counties are in North Carolina, two are in Kentucky, and the rest are in Tennessee (Figure 1.1-1). The largest city in the 50-mi radius is Knoxville, Tennessee. As of the 2010 Census, the population of Knoxville was 178,874 persons. All of the other cities and towns in the region have populations of less than 50,000. Other than Knoxville, only three cities have populations of over 20,000: Oak Ridge (29,330), Maryville (27,601) and Farragut (20,676),
Tennessee.
Four interstate highways traverse the region, I-40, I-75, I-640, and I-140 (Figure 2.1-1).
Subsection 2.5.2.2, Transportation, provides a description of the transportation network in the vicinity of the CRN Site. The Clinch River provides a navigable corridor between Clinton, Tennessee and Kingston, Tennessee, where it joins with the Tennessee River (Watts Bar Reservoir) and thus ultimately provides transport to the Gulf of Mexico (Reference 2.2-21). The Clinch River (Melton Hill Reservoir) is designated a state scenic river from above the Melton Hill Dam to below the Norris Dam (Reference 2.2-22). The closest commercial airports located within the CRN region are the McGhee Tyson Airport and the Knoxville Downtown Island Airport (Figure 2.1-1).
Based on the USGS land-cover classification standards and the 2011 NLCD, land use and land cover in the CRN Site vicinity is categorized and shown in Table 2.2-1 and Figure 2.2-5.
Forested land (deciduous, evergreen, or mixed forest) accounts for approximately 62 percent of the region. Wetlands (emergent herbaceous or woody wetlands) occupy less than 1 percent of 2.2-6                                    Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report the region. Other vegetated undeveloped land (grassland/herbaceous or shrub/scrub) totals approximately 8 percent of the region. Land classified as cultivated crops and pasture/hay totals approximately 16 percent of the region. Open water or barren land occupy approximately 3 percent of the region. The remaining approximately 11 percent of the region is classified as developed (high, medium, or low intensity, or open space). According to the USDA, in 2007 Anderson Countys top crop in terms of acreage was forage (9160 ac) and the top livestock inventory items were cattle and calves, producing a total of 4.4 million dollars of agricultural products that year (Reference 2.2-23). In Roane County, the top crop was also forage (11,383 ac) and the top livestock items were cattle and calves, producing a total of 5.1 million dollars of agricultural products (Reference 2.2-24). In Loudon County the top crop is forage (21,136 ac) and the top livestock items are also cattle and calves, producing 60 million dollars of agricultural products (Reference 2.2-25). Knox County has a similar agricultural regime, with forage the top crop (21,673 ac) and cattle and calves the top livestock, producing a total of 19 million dollars of agricultural products (Reference 2.2-26).
Federal lands in the region include the ORR, the Watts Bar Dam Reservation, the Melton Hill Dam Reservation, Great Smoky Mountains National Park, Cherokee National Forest, Big South Fork National River and Recreational Area, and Daniel Boone National Forest. Most of these federal lands offer camping, fishing, swimming, boating, and other recreational activities for visitors. The ORR includes three DOE campuses with distinct missions. The ORNL is the DOEs largest multi-purpose laboratory conducting research in advanced materials exploration, alternative fuels, climate change, and supercomputing. Two of the laboratorys more significant facilities include the Spallation Neutron Source facility, a center for neutron science research, and the High Flux Isotope Reactor, an 85-megawatt high flux reactor-based source of neutrons.
The Y-12 Complex mission includes modernizing defense systems and reducing nuclear stockpiles worldwide. The East Tennessee Technology Park is located on the site of a former uranium enrichment complex, which is currently being remediated, revitalized, and transitioned into a private sector business/industrial park. Seasonal hunting activities are available on the ORR as well. (Reference 2.2-27) 2.2.3    Transmission Corridors and Offsite Areas There are currently two transmission corridors crossing the CRN Site (Figure 2.2-6). The Kingston FP - Ft Loudoun HP 161 kV No.1 transmission line crosses the CRN Site from the southeastern tip of the peninsula to the northwestern corner of the CRN Site near the entrance gate. The Bull Run FP-Watts Bar NP 500 kV transmission line transverses the CRN Site northeast to southwest.
Onsite and offsite transmission lines are to be modified for the project. Onsite transmission lines are to be modified by relocating the 161 kV line to accommodate placement of the CRN facility.
Offsite transmission lines are modified through the establishment of a 69kV underground transmission line from the Bethel Valley Substation to the CRN facility and upgrades needed to support stability of the TVA power grid. This 69 kV transmission line is to be placed within the existing 500 kV line right-of-way (Figure 2.2-6). Transmission line segments requiring upgrades 2.2-7                                    Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report are shown in Figure 2.2-7. Ten 161 kV transmission lines over a distance of 191 mi would require uprating. An additional sixteen 161 kV transmission lines over a distance of 122 mi would require uprates or reconductoring. Modifications related to uprating and reconductoring would affect a total of 2317 and 1476 ac respectively. Finally, one section of a 12.7 mi long transmission line would require rebuilding covering a total of 154 ac. All actions related to offsite transmission line modifications would occur within the existing transmission line rights-of-way.
Figure 2.2-10 shows the federal and tribal lands, wildlife areas and refuges, wilderness areas, and parks in the vicinity of these offsite transmission lines. Detailed information regarding changes associated with the transmission lines, including lengths of individual segments affected, is discussed in Section 3.7.
Additional offsite areas include the rail offloading area, the Barge/Traffic Area, and several existing borrow pits. TVA anticipates utilizing the EnergySolutions Heritage Railroad rail siding near the CRN Site for deliveries. The refurbishment of this rail siding is addressed in the DOEs Environmental Assessment, Transfer of Land and Facilities Within the East Tennessee Technology Park and Surrounding Area, Oak Ridge, Tennessee (DOE/EA-1640) (Reference 2.2-28).
Roadway improvements are required in the Barge/Traffic Area and an existing barge terminal (that was used for TN 58 construction) in that area is to be refurbished (Figure 2.2-6). Based on the USGS land-cover classification standards and the 2011 NLCD, land use and land cover in the Barge/Traffic Area is categorized and shown in Table 2.2-1 and Figure 2.2-5. Forested land (deciduous, evergreen, or mixed forest) accounts for approximately 53 percent of the Barge/Traffic Area. Wetlands (emergent herbaceous or woody wetlands) occupy approximately 5 percent of the Barge/Traffic Area. Other vegetated undeveloped land (grassland/herbaceous or shrub/scrub) totals less than 1 percent of the Barge/Traffic Area. Land classified as cultivated crops and pasture/hay total approximately 16 percent of the Barge/Traffic Area. Open water or barren land occupy approximately 5 percent of the Barge/Traffic Area. The remaining approximately 21 percent of the Barge/Traffic Area is classified as developed (high, medium, or low intensity, or open space). The Barge/Traffic Area and the rail offloading area are located within the 6 mi CRN Site vicinity.
Fill material will be required for the CRN Site. In addition to potentially using borrow material from the CRN Site, offsite borrow sources may be used. The volume of fill material and selection of the source for fill material will be dependent on the backfill plan and the required material properties identified by analyses performed in support of the COLA. Material excavated from portions of the CRN Site will be characterized in accordance with the backfill plan to determine whether the material has the characteristics and provides the needed quantities for use as fill on the site. If additional fill material is need from offsite, the borrow source(s) will be selected based on material properties and quantities available at the potential source locations.
The soil quality at each potential borrow site will be required to meet the criteria for acceptability for use as fill material at the CRN Site.
2.2-8                                    Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Offsite borrow areas that have been identified for possible use are shown in Figure 2.2-8. At least two of the borrow sites identified in Figure 2.2-8 are currently being utilized in support of other TVA projects. The total acreage of these nine potential borrow sites is 227 ac. The combined volume of fill material present in the disturbed and fully permitted offsite borrow areas is anticipated to meet the volume of fill material that would be needed for the CR SMR Project.
Therefore, it is unlikely that any existing borrow areas would need to be expanded beyond currently permitted boundaries or that any new borrow areas would need to be opened to accommodate the CR SMR Project.
The borrow pits are located within the 50 mi CRN Site region.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3      WATER This section describes the physical, chemical, biological, and hydrological characteristics of surface water and groundwater in the vicinity of the Clinch River Nuclear (CRN) Site that may affect water supply or that may be reasonably assumed to be affected by the construction and operation of two or more small modular reactors (SMRs). The following lists the Section 2.3 subsections, with descriptions:
* Subsection 2.3.1 provides a detailed description of the surface water bodies and groundwater aquifers that can affect the CRN Site water supply and effluent disposal or may be affected by construction or operation of the SMRs.
* Subsection 2.3.2 describes surface water and groundwater uses in the vicinity of the facility that can affect or be affected by the construction and operation of two or more SMRs.
* Subsection 2.3.3 provides detailed water quality information regarding the surface water and groundwater in the vicinity of the CRN Site.
2.3.1    Hydrology This subsection presents descriptions of the surface water and groundwater resources that could be affected by the construction and operation of two or more SMRs. The physical and hydrologic water resource characteristics of the site and region are summarized below.
2.3.1.1    Surface Water The CRN Site is located on a peninsula created by a bend in the Clinch River arm of Watts Bar Reservoir (Figure 2.3.1-1). The CRN Site is located between approximately Clinch River Mile (CRM) 14.5 and approximately CRM 19.0 and is approximately 10.7 miles (mi) southwest of the City of Oak Ridge, Tennessee. Within the CRN Site, the proposed surface water intake is located at CRM 17.9, and the proposed discharge is located at approximately CRM 15. 5. The Barge/Traffic Area is located between CRN 14.0 and CRN 14.5.
The location of the CRN Site and Barge/Traffic Area with respect to major surface water features is shown in Figure 2.3.1-1. The upstream boundary of the CRN Site is located approximately 4.1 mi downstream of Melton Hill Dam, which is located at CRM 23.1. The CRN Site is located approximately 8.2 mi east of the confluence of the Tennessee and Clinch Rivers, with the downstream boundary of the site about 14.5 mi upstream of the confluence. The confluence of the two rivers is located at CRM 0 on the Clinch River, and at Tennessee River Mile (TRM) 567.8 on the Tennessee River (Reference 2.3.1-1). Further downstream on Watts Bar Reservoir, Watts Bar Dam is located at TRM 529.9 or 52.4 mi downstream of the CRN Site (Reference 2.3.1-2). Regulated releases of surface water to Watts Bar Reservoir are made not only from Melton Hill Dam but also Fort Loudoun Dam located at TRM 602.3, and Tellico Dam located near TRM 601.1.
2.3.1-1                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report As shown on Figure 2.3.1-1, a number of creeks located in the vicinity of the CRN Site discharge into the reservoir (Figure 2.3.1-1). Upstream of the CRN Site, between Melton Hill Dam at CRM 23.1 and the intake at CRM 17.9, three streams enter the reservoir. These include: Whiteoak Creek, entering the reservoir from the north at CRM 21.0; Raccoon Creek, entering the reservoir from the north at CRM 19.5; and Paw Paw Creek, entering the reservoir from the south at CRM 19.3. Within the reach of the CRN Site, four streams enter the reservoir.
These include: Caney Creek, entering the reservoir from the south at CRM 17.0; Poplar Springs Creek, entering the reservoir from the south at CRM 16.2; Bear Creek, entering Poplar Creek and subsequently entering the reservoir at CRM 12, and Grassy Creek entering the reservoir from the north at CRM 14.5. One other prominent tributary, the Emory River, enters the reservoir between the CRN Site and the Tennessee River. The Emory River enters the reservoir from the north, at CRM 4.5 (Reference 2.3.1-3).
2.3.1.1.1  Hydrologic Setting Tennessee River Watershed The headwaters of the Tennessee River watershed originate in the mountains of western Virginia and North Carolina, eastern Tennessee, and northern Georgia. The Tennessee River is formed by the confluence of the Holston and the French Broad Rivers near Knoxville, Tennessee. The river flows to the southwest and receives water from three principal tributaries:
Little Tennessee, Clinch, and Hiwassee Rivers. As the Tennessee River flows south, west, and then north, two other major tributaries, the Elk and Duck rivers, contribute to the flow that eventually joins the Ohio River at Paducah, Kentucky. (Reference 2.3.1-4)
The Tennessee River and its tributaries have a drainage area of approximately 41,910 square (sq) mi and pass through 125 counties that cover much of Tennessee and parts of Alabama, Kentucky, Georgia, Mississippi, North Carolina, and Virginia (Reference 2.3.1-5). The drainage area from the point of headwater origination to Chattanooga, Tennessee, is approximately 21,400 sq mi; west of Chattanooga to the Ohio River, the drainage area is approximately 19,500 sq mi (Reference 2.3.1-4).
The Tennessee River watershed is subdivided by the U.S. Geological Survey (USGS) into 32 hydrologic units, each identified by a hydrologic unit code (HUC). The USGS divides the Tennessee River Basin into two subbasins: the Upper Tennessee River Basin and the Lower Tennessee River Basin. The boundary between these subbasins is TRM 465 on the mainstem of the Tennessee River at Chattanooga, Tennessee. (Reference 2.3.1-5)
The CRN Site is located in the Upper Tennessee River Basin. The Upper Tennessee River Basin contains some of the most rugged terrain in the eastern United States, including the Great Smoky Mountains range. The Upper Tennessee River Basin encompasses approximately 21,400 sq mi and includes the entire drainage area of the Tennessee River and its tributaries upstream from the USGS gaging station in Chattanooga, Tennessee. It also includes parts of four states: Tennessee, 11,500 sq mi; North Carolina, 5480 sq mi; Virginia, 3130 sq mi; and 2.3.1-2                                    Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Georgia, 1280 sq mi. Parts of three physiographic provinces (Cumberland Plateau, Valley and Ridge, and Blue Ridge) compose the Upper Tennessee River Basin. Elevations range from 621 feet (ft) above mean sea level (msl) at Chattanooga to 6684 ft msl at Mount Mitchell, which is located just northeast of Asheville, North Carolina, and is the highest point in the eastern United States. (Reference 2.3.1-6)
Tennessee River Management The Tennessee River system, managed by the Tennessee Valley Authority (TVA), is a network of dams and reservoirs that generates power, controls flooding, provides recreational opportunities, and boosts the regional and national economies. The Tennessee River system has approximately 11,000 mi of public shoreline, and under Section 26a of the TVA Act, TVA has the authority to regulate land use and development along the shoreline. TVA owns or operates 49 dams and reservoirs in the mainstem Tennessee and Cumberland watersheds, including nine dams on the Tennessee River (Reference 2.3.1-7). The dams and reservoirs are operated year-round by TVA for the purposes of navigation, flood control, power generation, water supply, water quality, and recreation. Operation of the reservoirs is linked to rainfall and runoff patterns in the watershed. (Reference 2.3.1-8)
Clinch River Watershed The Clinch River originates in Southwest Virginia and flows to the southwest while receiving water from a number of tributaries, including the Powell River, above Norris Dam. The Clinch River is more than 300 mi long, formed by the junction of two forks in southwestern Virginia and flowing generally southwest across eastern Tennessee towards its confluence with the Tennessee River at Kingston, Tennessee. The Clinch River watershed has a drainage area of approximately 4413 sq mi. (Reference 2.3.1-5)
The CRN Site lies within the Lower Clinch River Watershed (USGS HUC 06010207).
Surrounding the Lower Clinch River Watershed are the Powell, Holston, Lower French Broad, Tennessee River (Watts Bar Reservoir), and Emory watersheds. The Lower Clinch River Watershed includes portions of eight counties in East Tennessee including Anderson, Campbell, Grainger, Knox, Loudon, Morgan, Roane, and Union. (Reference 2.3.1-9)
Clinch River Management The CRN Site includes approximately 935 acres (ac) of land on the north side of the Clinch River arm of the Watts Bar Reservoir between approximately CRM 14.5 and CRM 19.0. The upstream boundary of the CRN Site is approximately 4.1 mi downstream of Melton Hill Dam, which is located at CRM 23.1. The portion of the Clinch River below Melton Hill Dam is part of Watts Bar Reservoir, an impoundment created by Watts Bar Dam, located on the Tennessee River at TRM 529.9, approximately 52.35 mi downstream of the CRN Site (Reference 2.3.1-2).
There are four dams upstream of the CRN Site which may affect the hydrology of the site:
2.3.1-3                                    Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* Norris Dam located at CRM 79.8
* Melton Hill Dam located at CRM 23.1
* Whiteoak Dam and Whiteoak Creek Embayment Sediment Control Dam, on Whiteoak Creek located near CRM 21.0 (Reference 2.3.1-3; Reference 2.3.1-10)
Norris Dam is located approximately 60.8 mi upstream from the CRN Site, and forms the Norris Reservoir. Norris Reservoir is the confluence of the Powell and Clinch River basins, and it is one of the largest of TVAs 10 tributary storage reservoirs (Reference 2.3.1-11). The dam was completed in 1936 and is 265 ft high and stretches 1860 ft across the Clinch River. It is a hydroelectric facility with two generating units with a net dependable capacity of 110 megawatts (MWe). With normal rainfall throughout the year, the water level in the reservoir fluctuates approximately 29 ft from summer to winter to provide seasonal flood storage. (Reference 2.3.1-12)
Melton Hill Dam is located on the Clinch River at CRM 23.1, approximately 4.1 river mi upstream of the CRN Site, and forms the Melton Hill Reservoir (Reference 2.3.1-3). The dam was completed in 1963 and is 103 ft high and stretches 1020 ft across the Clinch River. Melton Hill Dam is a hydroelectric facility with two generating units. These two generating units are capable of producing a net dependable capacity of 79 MWe. Melton Hill Reservoir has the only dam in the tributary reservoir system with a navigation lock, which has a 75- by 400-ft chamber and a maximum lift of 60 ft. (Reference 2.3.1-13)
Unlike most of TVAs multipurpose tributary projects, Melton Hill Dam does not provide any significant flood damage reduction benefits, nor does it provide any significant seasonal flow regulation because of the little useful storage volume available. The average weekly discharge from Melton Hill Dam over its lifetime (1962-present) is 4832 cubic ft per second (cfs) with a maximum weekly discharge of 25,455 cfs. Figure 2.3.1-3 shows the expected flow frequency of the weekly average flow from Melton Hill Dam based on 100 years (yr) of reservoir and system simulation conducted for the development of the current reservoir operating policy. The minimum discharge requirement for Melton Hill is 400 cfs average daily flow, but the frequency of this minimum flow continuing for as long as seven days is less than 0.1 percent as shown in Figure 2.3.1-3. (Reference 2.3.1-11)
The two dams on Whiteoak Creek are located near its confluence with the Clinch River arm of the Watts Bar Reservoir, near CRM 21.0. The primary dam is Whiteoak Dam, constructed in 1943 to contain radioactive sediment and minimize the spread of contamination from past activities on what is now the U.S. Department of Energy (DOE) Oak Ridge Reservation (ORR).
Whiteoak Dam forms the 25-ac Whiteoak Lake, which has a drainage area of 6.0 sq mi.
immediately downstream of the Whiteoak Dam is Whiteoak Creek Embayment, which is separated from the Clinch River arm of the Watts Bar Reservoir by Whiteoak Creek Embayment Sediment Control Dam. The Sediment Control Dam was constructed in 1992 in order to maintain a constant water level and prevent fluctuations in water level in Whiteoak Creek Embayment due to storm flows and TVA power operations. (Reference 2.3.1-14) 2.3.1-4                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Two other dams, neither located on the Clinch River, affect the surface water hydrology of the Watts Bar Reservoir at the CRN Site. These are:
* Watts Bar Dam, located at TRM 529.9 (Reference 2.3.1-2)
* Fort Loudoun Dam located at TRM 602.3.
Watts Bar Dam is located on the Tennessee River at TRM 529.9, approximately 52.35 river mi downstream of the CRN Site (Reference 2.3.1-2). Construction on the Watts Bar Dam began 1939 and was completed in 1942. Watts Bar Dam is 112 ft high and stretches 2960 ft across the Tennessee River. All outflows from Watts Bar Reservoir are controlled by releases at Watts Bar Dam. Watts Bar Dam has one lock that is 60 ft by 360 ft and lifts and lowers barges as high as 70 ft from the Watts Bar Reservoir to the Chickamauga Reservoir. The net dependable capacity at Watts Bar Dam is 182 MWe. In addition to forming the navigable reservoir on the Tennessee River, the Watts Bar Dam also creates a slack-water channel for navigation more than 20 mi up the Clinch River to the Melton Hill Dam, and 12 mi up the Emory River. (Reference 2.3.1-7)
Regulated releases of surface water enter Watts Bar Reservoir not only by releases from Melton Hill Dam but also from Fort Loudoun Dam, located on the Tennessee River at TRM 602.3.
Construction on Fort Loudoun Dam began in 1940 and was completed in 1943. Fort Loudoun Dam is 122 ft high and stretches 4190 ft across the Tennessee River. The Fort Loudoun lock is 60 ft by 360 ft, and raises and lowers river craft approximately 70 ft between the Fort Loudoun Reservoir and the Watts Bar Reservoir. The net dependable capacity of Fort Loudouns four units is 162 MWe. Fort Loudoun Reservoir is connected by a short canal to Tellico Reservoir on the nearby Little Tennessee River. Water is diverted through the canal to Fort Loudoun for power production. The canal also offers commercial barges access to Tellico Reservoir without the need for a lock. (Reference 2.3.1-15)
Just downstream of Fort Loudoun Dam, at approximately TRM 601.1, Tellico Dam also can provide regulated releases to Watts Bar Reservoir from the Little Tennessee River. However, Tellico Dam contains only a spillway (i.e., no hydro capabilities), which is operated very rarely, only in extreme flood events.
Local Site Drainage The CRN Site covers approximately 935 ac and is bounded to the west, south, and east by the Clinch River arm of Watts Bar Reservoir and to the north by the DOE ORR. As stated in Subsection 2.2.1.1 and shown in Figure 2.2-1, a series of roughly parallel ridges of gradually lower elevations stretches from the Chestnut Ridge, near the CRN Site entrance and in the Grassy Creek Habitat Protection Area (HPA), to approximately the center of the peninsula.
In addition to the Clinch River arm of the Watts Bar Reservoir, TVA identified four perennial streams and one intermittent stream on the CRN Site, and one perennial stream and three 2.3.1-5                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report intermittent streams in the Barge/Traffic Area1. Hydrologic flow within all of these streams is affected by precipitation and stormwater runoff. In addition, hydrologic flow within the Clinch River arm of the Watts Bar Reservoir (stream S02) and a tributary to the reservoir (stream S04) are affected by water levels within the reservoir. Hydrologic flow within streams S01, S06, and S08 is also affected by discharge from springs. (Reference 2.3.1-16) Descriptions of these streams are included in Subsection 2.4.2.1.3 and Table 2.4.2-5, and their locations are shown in Figure 2.4.1-2.
TVA also identified 19 ephemeral streams/wet-weather conveyances (WWCs) on the CRN Site, and 15 WWCs at the Barge/Traffic Area (Reference 2.3.1-16). WWCs are natural or constructed drainages that have flow conditions only in direct response to precipitation and stormwater runoff (Reference 2.3.1-17). Descriptions of these WWCs are included in Subsection 2.4.2.1.3 and Table 2.4.2-5, and their locations are shown in Figure 2.4.1-2.
Six man-made ponds were identified on the CRN Site, and two ponds were identified in the Barge/Traffic Area. The ponds on the CRN Site were constructed as part of a stormwater management system, and their hydrology is caused by precipitation and stormwater runoff.
(Reference 2.3.1-16) Descriptions of these ponds are included in Subsection 2.4.2.1.3 and Table 2.4.2-5, and their locations are shown in Figure 2.4.1-2.
Local Wetland Areas TVA identified and delineated 12 wetlands on the CRN Site. Each wetland is described in Subsection 2.4.1.2 and shown on Figure 2.4.1-2. Hydrologic flow within each of these wetlands is affected by precipitation and stormwater runoff. In addition, hydrologic flow within wetlands W003, W005, W007, W008, and W011 is influenced by water levels within the Clinch River arm of the Watts Bar Reservoir. Hydrologic flow within four wetlands (W005, W008, W009, and W010) is also affected by groundwater discharge. (Reference 2.3.1-18) TVA also identified and delineated five wetlands at the Barge/Traffic Area. Hydrologic flow within these wetlands is also affected by precipitation and stormwater runoff. In addition, hydrologic flow within one of these wetlands (W017) is influenced by water levels within the Clinch River arm of the Watts Bar Reservoir (Reference 2.3.1-19).
2.3.1.1.2  Reservoir Characteristics Three separate reservoirs can potentially affect, or be affected, by SMR operations. The impoundments are:
* Melton Hill Reservoir
* Watts Bar Reservoir 1
Surveys were conducted on the portions of the Barge/Traffic Area (101-ac.) with the highest potential for disturbance that had not been previously surveyed.
2.3.1-6                                      Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* Fort Loudoun Reservoir Melton Hill Dam, located on the Clinch River 4.1 mi upstream of the CRN Site, impounds Melton Hill Reservoir and releases water into the Clinch River arm of the Watts Bar Reservoir. The Clinch River arm of the Watts Bar Reservoir is the source and receiving water body for CR SMR plant operations. Fort Loudoun Dam, on the mainstem of the Tennessee River, releases water from Fort Loudon Reservoir into Watts Bar Reservoir. Therefore, operation of the Fort Loudoun Dam can affect water levels and other characteristics of the Watts Bar Reservoir.
Reservoir Description Under flood conditions, TVAs water management objective for Melton Hill, Watts Bar and Fort Loudon Reservoirs and most other dams within the system is to operate the reservoir system to minimize flood damage by timing turbine discharges, gate openings, and spillway discharges as required.
Melton Hill Reservoir is on the Clinch River, extends almost 57 mi upstream from Melton Hill Dam to Norris Dam, and drains approximately 628 sq mi. Figure 2.3.1-1 illustrates the location of Melton Hill Dam and Melton Reservoir relative to the CRN Site. The reservoir provides nearly 193 mi of shoreline and 5470 ac of water surface for recreation. (Reference 2.3.1-13) It is a run-of-river reservoir, meaning water is passed through the reservoir without being stored long-term and allows barge traffic up to Clinton, Tennessee. Melton Hill Reservoir is a multipurpose reservoir providing for navigation, hydroelectric power production, water supply, water quality, and recreation. The average residence time for water in the reservoir is approximately 11 days (Reference 2.3.1-8). Actual elevations of the reservoir immediately upstream of the dam are measured continuously. The elevation range of normal operation fluctuates between 793 and 795 ft msl (Reference 2.3.1-13).
Watts Bar Dam forms the Watts Bar Reservoir. Watts Bar Reservoir is located on the Tennessee River and extends approximately 72.4 mi upstream from Watts Bar Dam to Fort Loudoun Dam (Reference 2.3.1-2). The reservoir drains approximately 17,310 sq mi and has 722 mi of shoreline and over 39,090 ac of water surface. The reservoir has a flood-storage capacity of 379,000 ac-ft. (Reference 2.3.1-7) The average residence time for water in the reservoir is approximately 17 days (Reference 2.3.1-8).
Discharging from Melton Hill Dam, the Clinch River forms only a small portion of the Watts Bar Reservoir. The Tennessee River below Fort Loudoun Dam comprises the main body of the reservoir. The water elevation in Watts Bar Reservoir is controlled by releases from Watts Bar Dam. The water elevation in Watts Bar Reservoir is generally maintained between 735 ft msl and 741 ft msl. (Reference 2.3.1-11)
The CRN Site Probable Maximum Flood (PMF) elevation is 799.9 ft National Geodetic Vertical Datum of 1929 (NGVD29). The combined effect maximum flood level is 806.0 ft NGVD29.
2.3.1-7                                Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Fort Loudoun Reservoir is the uppermost in the chain of nine TVA reservoirs that form a continuous navigable channel on the Tennessee River. The average residence time for water in the reservoir is approximately 10 days (Reference 2.3.1-8). The reservoir has 379 mi of shoreline and 14,600 ac of water surface. It has a flood storage capacity of 111,000 ac-ft. To maintain the water depth required for navigation, Fort Loudoun Reservoir is kept at a minimum winter elevation of 807 ft. The typical summer operating elevation is between 812 and 813 ft.
(Reference 2.3.1-15)
River flow direction at the CRN Site can be upstream, downstream, or quiescent, depending on the modes of operation of Melton Hill Dam, Watts Bar Dam, and Fort Loudoun Dam. Flow reversal may occur from an abrupt shutdown of Melton Hill and Watts Bar Dams and by releasing water from Fort Loudoun Dam. (Reference 2.3.1-11)
Reservoir Operating Rules TVA adopted its current reservoir operating policy in 2004 based upon the comprehensive Reservoir Operations Study (ROS), which was conducted in cooperation with the U.S. Army Corps of Engineers (USACE) and the U.S. Fish and Wildlife Service (USFWS) as well as representatives of other agencies and members of the public. Two of the features of the operating policy pertinent to this discussion are that it was designed to meet the future off-stream water needs in the Tennessee Valley as well as maintain minimum stream flow at critical locations in the Valley. (Reference 2.3.1-11)
The operating policy requires TVA to store water in tributary reservoirs during the spring when there is relatively high surface water flow into the reservoir system for release during the summer when there is relatively little surface water flow into the system. An important requirement of the operating policy is to meet minimum flow targets. Each of the 10 major tributary projects has such a target. There are also system minimum flow targets on main-stem projects. Chickamauga and Kentucky are projects with key system minimum flow targets.
(Reference 2.3.1-11)
The individual tributary project minimum releases provide for instream flow uses such as aquatic habitat in the tailwaters below the projects. These project minimum flows plus additional flow from local tributaries and Chickamauga or Kentucky Dams comprise the system minimum flow.
When the surface water flow from local tributaries is too low to meet the governing system minimum flow target, the tributary project releases are increased until the governing system minimum flow target is reached. (Reference 2.3.1-11)
Because rainfall varies across the watershed from year to year, there are some years when reservoirs on one tributary river have relatively less water in them than reservoirs on another tributary river. The operating policy requires TVA to balance the drawdown from all the tributary projects, which slows the drawdown on reservoirs at relatively low levels and increases the drawdown on reservoirs at relatively high levels. (Reference 2.3.1-11) 2.3.1-8                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report TVA uses Operating Guides for each reservoir to determine the timing and volume of releases from the dams. The Operating Guides are based on decades of operating experience, and are developed to provide seasonal variation in water levels to accommodate flood waters. The Operating Guides provide a daily target for the water elevation in each reservoir. The operating guide for the Headwater Elevation (HWEL) at Watts Bar Dam is shown in Figure 2.3.1-4. In the winter, TVA targets a pool elevation at Watts Bar Dam between approximately 735 ft and 737 ft msl. Between late March and mid-May, the reservoir is filled to the summer operating range, targeting a pool elevation between approximately 740 ft and 741 ft msl. Between late October and early December the pool is returned to the winter operating range.
Intake and Discharge Description As shown in Figure 2.3.1-1, water for the plant cooling system is withdrawn from the Clinch River arm of the Watts Bar Reservoir by an intake structure located near CRM 17.9. Heated water from the plant is returned to the reservoir by a discharge structure located at about CRM 15.5.
Flow To evaluate the hydrothermal impact of the proposed SMRs on Watts Bar Reservoir, TVA conducted a Hydrothermal Task Force study which evaluated the historical data regarding water flow in the reservoir. The following subsection is adapted from the Hydrothermal Task Force Report, and describes the flow information relevant to the analysis of hydrothermal impacts.
The release from Melton Hill Dam is the main source of water for the Clinch River arm of the Watts Bar Reservoir at the CRN Site. The current operating policy of the TVA river system, implemented in 2004, is defined by the TVA Reservoir Operations Study, or ROS (Reference 2.3.1-8). Historical river data used in the hydrothermal analyses was limited to ROS years, beginning in 2004. This is because the operating policy of the TVA river system for the period of operation of the SMRs is expected to be the same as the current ROS operating policy. Under the ROS operating policy, the daily average releases from Melton Hill Dam for 2004 through 2013 are shown in Figure 2.3.1-5. For this period, the overall average release, and consequently the expected approximate average river flow past the CRN Site, is approximately 4670 cfs. The maximum Melton Hill Dam daily average release observed for this period is approximately 21,700 cfs. The minimum single-day average release may be 0 cfs.
The ROS guideline for the minimum daily average release from Melton Hill Dam is 400 cfs.
Shown in Figure 2.3.1-6 is the percentile for the Melton Hill Dam daily average release shown in Figure 2.3.1-5. Approximately 60 percent of the time, the scheduled daily average release for Melton Hill Dam is less than the overall average flow (i.e., less than 4670 cfs). The minimum daily average release of 0 cfs cited above occurred on Monday, December 22, 2008, the day of the coal ash spill in the Emory River at the Kingston Fossil Plant, located approximately 14 mi downstream of the CRN Site. Since the Kingston ash spill, TVA has maintained the 400 cfs minimum daily average release for Melton Hill Dam.
2.3.1-9                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report The powerhouse at Melton Hill Dam contains two hydro generating units. The operation of the hydro units can provide a minimum release of between approximately 4000 cfs and 5000 cfs (one unit at minimum load) and a maximum release of between approximately 21,000 cfs and 23,000 cfs (two units at maximum load). On an hourly basis, Melton Hill Dam releases usually are scheduled in keeping with TVAs desire to provide low cost power. In this context, and due to the high flexibility and low fuel cost for hydropower, the Melton Hill Dam daily allotment of water is usually dispatched during those hours when the price for power is at or near the daily peak. In this manner, little or no releases are made during other hours of the day. This scheduling pattern is known as hydro peaking. Figure 2.3.1-7 shows the percentile for Melton Hill Dam hourly releases for the period 2004 through 2013 (i.e., since implementation of the current TVA reservoir operating policy). Approximately 50 percent of the time there are no hourly releases from Melton Hill Dam (i.e., flow of 0 cfs). When the daily allotment of water from Melton Hill Dam is very low (e.g., when dry conditions dictate a daily average flow approaching the ROS minimum of 400 cfs) the daily allotment can be provided by only one hour of hydro operation per day. If this type of operation is provided in the first hour of one day and the last hour of the following day, there can be up to 46 continuous hours of no releases from Melton Hill Dam. Although this is possible when following the current operating policy, such usually does not occur in practice. Figure 2.3.1-8 shows the average annual frequency of no release events from Melton Hill Dam for the period 2004 through 2013. On the average, the number of no release events per year is approximately 425. The average duration of these events is approximately 11.25 hours (hr). On the average, the number of no release events lasting more than 24 hr is only approximately 9 per yr. Events with no Melton Hill Dam releases for periods in excess of 36 hr are extremely rare, on the average less than one event per year.
Regional Surface Water Evaporation Mean monthly, seasonal, and annual pan evaporation for the Tennessee River Basin was evaluated using the National Oceanic and Atmospheric Administration Mean Monthly, Seasonal and Annual Pan Evaporation for the United States technical report. Table 2.3.1-1 lists average pan evaporation based on estimates of monthly evaporation derived from hydrometeorological measurements, using a form of the Penman equation described by Kohler, et. al. in 1955.
Using data from Table 2.3.1-1, average annual evaporation in Tennessee is 52.01 inches (in.),
and average annual evaporation for the Knoxville station near the CRN Site is 50.61 in.
Water Surface Elevation and Current Patterns The water surface elevation (WSEL) for the section of the Clinch River arm of the Watts Bar Reservoir adjacent to the CRN Site, in general, follows the pool elevation at Watts Bar Dam.
The current pattern in the river is usually in the downstream direction. Figure 2.3.1-9 shows the daily average WSEL measured at the CRN Site (at CRM 16.1) and the daily average HWEL measured at the Watts Bar Hydro plant. The data are for 2013. The daily average WSEL at CRM 16.1 varies between 736 and 744.5 ft above mean sea level, a range of approximately 8.5 ft. The WSEL follows the general trend of daily average HWEL at Watts Bar Dam. However, 2.3.1-10                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report differences occur between the WSEL at the CRN Site and WSEL at Watts Bar Dam due to hydraulic conditions between the site and Watts Bar Dam. At the CRN Site, the surface water flow from Melton Hill Dam provides the greatest influence on local variations in WSEL. During periods when the daily average release from Melton Hill Dam was in excess of approximately 5000 cfs (e.g., late January and early February 2013), it was not uncommon for the WSEL at the CRN Site to rise 1.0 ft or more above the HWEL at Watts Bar Dam. This dynamic also occurs at smaller time scales. For example, on an hourly basis, peaking operations at Melton Hill Dam can cause the WSEL at the CRN Site to rise above the HWEL at Watts Bar Dam.
Sloshing of the reservoir from peaking operations at the Watts Bar, Melton Hill, and Fort Loudoun hydro plants also can cause the opposite to occur, with the WSEL at the CRN Site falling below the HWEL at Watts Bar Dam. During these events, the current pattern in the Clinch River arm of the Watts Bar Reservoir is reversed, with flow moving upstream rather than downstream.
Figure 2.3.1-10 shows the maximum, minimum, and average values of the daily midnight HWEL at Watts Bar Dam for the period of record from 2004 through 2013 (the years encompassing the current ROS operating policy). Large rainfall/runoff (flood) events caused the HWEL at Watts Bar Dam to spike above the target operating ranges. Such events are apparent in Figure 2.3.1-10.
Temperature and Water Velocity Measurements For the ROS operating period including 2004 and 2008 through 2013, Figure 2.3.1-11 shows an estimate of the hourly water temperature in the tailwater below Melton Hill Dam. The data is a composite of information from several locations. These include: (1) monitors on the taildeck at Melton Hill Dam, (2) monitors for the generator cooling water inside the dam, (3) a monitor in the tailrace about 0.5 miles downstream of the dam (CRM 22.6), and (4) a monitor in the river about 19.2 mi downstream (CRM 3.9). Composite data are used because no single monitor provides valid data throughout the entire period of record. For years 2005, 2006, and 2007, equipment outages with the Melton Hill Dam taildeck monitors resulted in no usable data for those years.
Composite data from the other locations are used primarily for 2004 and the first part of 2008.
Almost all of the data after May 2008 are from the monitor in the tailrace about 0.5 mi downstream of the Melton Hill Dam.
In general, the water temperature for the portion of the Clinch River arm of the Watts Bar Reservoir immediately below Melton Hill Dam depends not only on meteorology, but also on the manner of operation of TVA facilities located upstream. Norris Dam, located at CRM 79.8, provides significant storage of cold water from winter and spring rainfall/runoff. Therefore, the manner of operation of Norris throughout the summer impacts the arrival of cold water at Melton Hill Dam. The Bull Run Fossil Plant, located at CRM 47.0, adds heat to Melton Hill Reservoir, thereby contributing to temperature stratification behind Melton Hill Dam. With this, scheduling of the number, magnitude, and duration of operation of the two hydro units at Melton Hill Dam affects the character of the withdrawal zone for the hydro intakes, and consequently the temperature of the water released downstream. All of these factors are represented in the 2.3.1-11                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report variability exhibited by the data in Figure 2.3.1-11. Because the basic operating policy of ROS is expected to continue in the future, the data in Figure 2.3.1-11 are considered adequate for estimating the potential range in release water temperature from Melton Hill Dam. The record encompassing 2004 and 2008 through 2013 includes a year of extreme drought (2008), a year of extreme rainfall (2013), a year of extreme summer heating (2010), and a year of extreme winter cooling (2011).
Figure 2.3.1-12 shows the daily maximum, minimum, and average values of the hourly temperature data presented in Figure 2.3.1-11. The data suggest hourly release temperatures from Melton Hill Dam range between approximately 39 degrees Fahrenheit (&deg;F) in the winter and 75&deg;F in the summer. The minimum reading occurred in 2010 and the maximum reading occurred in 2012. The proposed discharge structure for the CRN Site is located approximately 7.65 mi downstream of Melton Hill Dam. Depending on meteorology, the surface water in this reach may be cooled or warmed before it arrives at the SMR discharge. To examine the potential magnitude of this cooling and warming, 2013 data were examined for hourly water temperature measurements collected from the Melton Hill Dam tailrace monitor at CRM 22.6 and a temporary monitor installed at CRM 16.1. The percentile for the change in water temperature between the upstream (CRM 22.6) and downstream (CRM 16.1) monitor locations is shown in Figure 2.3.1-13. As shown, the change in hourly temperature generally varied between about -1&deg;F to +3&deg;F. As a result, for examining thermal impacts on the Clinch River arm of the Watts Bar Reservoir, the ambient temperature of the surface water was assumed to range between a minimum of 38&deg;F (winter) and maximum of 78&deg;F (summer).
In 2013, the temperature profile of the reservoir was also measured at CRM 13.0, 16.1, and 19.0, in order to evaluate the thermal regime and the presence of thermal stratification in the reach of the reservoir near the CRN Site. CRM 16.1 is near the proposed discharge location, and CRM 19.0 is approximately 1 mi upstream of the proposed intake location. Data were collected on a 15-minute basis. The profile at CRM 13.0 included measurements at depths of 3 ft, 10 ft, 20 ft, and at a bottom anchor. The measurements at CRM 16.1 were made at depths of 5, 10, and 15 ft. The measurements at CRM 19.0 were made at 3, 10, and 15 ft. At CRM 13.0, the water temperature differences between the 3 ft sensor and the bottom were generally on the order of 2-4&deg;F during the summer months and typically less than a degree during the winter months. The largest temperature gradient at all three locations occurred within the surface layer of the river. At the two upstream locations, the gradient between the surficial and deeper depths was even smaller than at CRM 13.0. The temperature difference at CRM 13.0 from the 10-ft depth to the bottom was minimal, typically on the order of 0.1 to 0.3&deg;F. The temperature gradient in summer often had a typical diurnal pattern, with a temperature peak occurring in the afternoon due to surficial warming during the hottest time of the day. This daily temperature gradient was then either flushed out by daily dam releases, or its heat dissipated with nighttime atmospheric cooling.
2.3.1-12                                Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Bathymetry In support of the hydrologic evaluation of the CRN Site, TVA performed hydrographic surveys of the Watts Bar Reservoir from CRM 13 to CRM 21. The surveys were performed in June 2013, using an automated sounding system operating at 200 khz. The survey consisted of 762 transects across the reservoir, and an additional 96 transects across the Emory River arm of the Watts Bar Reservoir.
A prominent feature of the bathymetry of the reservoir near the CRN Site is the presence of a submerged island near CRM 15.9. The bathymetry at this location is shown in Figure 2.3.1-14.
The conceptual plot plan for the CR SMR Project originally planned for the discharge to be located at CRM 15.9, directly adjacent to this feature. Based on TVAs hydrothermal modeling for the SMR discharge, TVA noted that the presence of this feature would encumber the mixing of the thermal effluent, resulting in a thermal plume hugging the shoreline. As a result, TVA modified the discharge location to approximately CRM 15.5, which is downstream of the island and in a location where the bathymetry would not interfere with mixing.
Erosion and Sediment Transport There are currently no site-specific data available on erosion and sediment transport in the vicinity of the CRN Site as evaluations rely on specific characteristics of the final plant design.
This information is to be developed as the facility design is completed, and is evaluated as part of the combined license application.
2.3.1.2      Groundwater Regional and local groundwater resources that could be affected by the construction and operation of the CRN Site are described in this subsection. Note that all references to elevation given in this subsection are to North American Vertical Datum of 1988 (NAVD 88) unless otherwise specified.
2.3.1.2.1  Description and Onsite Use This subsection describes the regional and local groundwater resources that could be affected by the construction and operation of the CRN Site.
The hydrogeologic conceptual model presented in this subsection was developed from multiple conceptual hydrogeologic models that vary in scale and hydrostratigraphic framework.
Considerations of the scale and framework were not mutually exclusive, but were intertwined during a series of steps designed to develop a tenable site hydrogeologic conceptual model.
Five steps were involved in the development of the scale-dependent conceptual models, and include:
: 1. A regional desktop study based on published state, Federal (including TVA and DOE ORR studies) and other sources.
2.3.1-13                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
: 2. A review of documentation to address the previously proposed, demonstration Clinch River Breeder Reactor Project (CRBRP) to be constructed at the site, including site-specific studies performed for the purpose of the CRBRP (Reference 2.3.1-20).
: 3. Review of preliminary SMR plant layout, plot plans and excavation plans for the CRN Site.
: 4. A site-specific geotechnical, geologic, and hydrogeologic field study conducted for the proposed CRN Site (Reference 2.3.1-21).
: 5. An evaluation of site-specific data in conjunction with regional and local information.
The first step of site model conceptualization involved formulating an understanding of the hydrogeologic conditions near the CRN Site including the ORR and surrounding areas.
Regional geologic and hydrogeologic information available from the USGS, Tennessee Department of Environment and Conservation (TDEC), DOE, TVA, and other sources were reviewed to identify the hydrogeologic framework of the area. The second step involved a review of documentation addressing local hydrogeologic conditions such as that available from the DOE and the subsurface studies performed in support of CRBRP previously proposed at the CRN Site. The third step was a review of the preliminary CR SMR plant layout, plot plans and excavation plans developed for the conceptual placement of the SMRs that could be constructed at the CRN Site.
During the fourth step, a site-specific subsurface investigation (SI) was implemented at the proposed CRN Site. The hydrogeologic aspects of the SI were based on the preliminary conceptual model (developed as described above) and were modified when appropriate during the field program (as field data were collected and evaluated), as the understanding of site-specific conditions for SMR construction evolved.
The fifth step involved analysis of the SI field data with the regional and local information. From this effort, site-specific data were integrated with existing CRN Site information and local and regional information to formulate the conceptual site model described in the following sections.
The conceptual model was then evaluated to determine potential changes to the hydrogeologic system as the result of constructing and operating the SMR units.
Physiography and Geomorphology The CRN Site is located in Roane County, Tennessee, within the City of Oak Ridge (Figure 2.3.1-15). The CRN Site is approximately 10.7 mi southwest of the center of the City of Oak Ridge, with the site and the city center separated by the ORR. The City of Kingston is approximately 7.2 mi west of the CRN Site. The closest major metropolitan center is Knoxville, approximately 25.2 mi to the east-northeast of the CRN Site.
The site is located on a peninsula formed by a meander of the Clinch River arm of the Watts Bar Reservoir between approximately river miles 14.5 and 19. Headwaters of the Clinch River are in Tazewell County, Virginia. From its headwater, the Clinch River flows approximately 350 mi in a southwesterly direction to its confluence with the Tennessee River near Kingston, Tennessee, 2.3.1-14                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report approximately 6 mi west of the CRN Site. The Clinch River basin is in an area of comparatively narrow parallel ridges and somewhat broader intervening valleys oriented in a northeast-southwest direction. The northwestern boundary of the basin is formed by the Cumberland Mountains, which range up to 4200 ft in elevation; the southeastern boundary follows Clinch Mountain and Black Oak Ridge with elevations ranging up to 4700 ft. (Reference 2.3.1-20)
Water levels in the Clinch River arm of the Watts Bar Reservoir, which surrounds the CRN Site to the east, south, and west, are regulated by TVA. The water elevation in Watts Bar Reservoir is generally maintained between 735 ft msl and 741 ft msl (Reference 2.3.1-11). Plant grade is at an elevation of approximately 821 ft NAVD 88; placing the SMRs about 80 ft above the water level of the river.
The CRN Site is located in eastern Tennessee near the western boundary of the Valley and Ridge Physiographic Province. The Valley and Ridge Physiographic Province is characterized by folded and faulted sedimentary geologic units of Paleozoic age, which produces a series of valleys and ridges. This province extends south through Georgia and Alabama and north to Pennsylvania and New Jersey (Reference 2.3.1-22).
In eastern Tennessee, the processes of folding, faulting, and erosion have resulted in a series of northeast trending ridges and valleys. Compressive forces from the southeast have caused these rocks to yield, first by folding and subsequently by repeated breaking along a series of thrust faults (Reference 2.3.1-22). This successive faulting has resulted in several outcropping units in the area that occur in parallel belts aligned roughly with the topography. The folding/faulting process has produced a repeated sequence of outcropping units. Major units present in the area include, from youngest to oldest, the Chickamauga Group, the Knox Group, the Conasauga Group, and the Rome Formation. All are composed primarily of Ordovician and Cambrian carbonate rocks. The dip of these formations is to the southeast in nearby Melton Valley in ORR (east of the CRN Site). Rock units generally strike between 50 and 60 degrees northeast, while dips vary with proximity to faults (Reference 2.3.1-23). Dips in Melton Valley are more gentle (10 to 20 degrees) away from the fault and steeper close to faults (45 to 90 degrees) (Reference 2.3.1-23). The extent of the Appalachian Ridge and Valley Region in eastern Tennessee is shown in Figure 2.3.1-16.
The topography of the site has been altered by anthropogenic changes. In 1972, the site was selected for permitting and construction of the CRBRP (Reference 2.3.1-24). Site preparation for the CRBRP began in September 1982. A Limited Work Authorization was granted by the U.S. Nuclear Regulatory Commission (NRC) in May 1983. Excavation for the nuclear island was completed in September 1983. Approximately three million cubic yards of earth and rock were excavated from the site (Reference 2.3.1-24). The Secretary of Energy issued a statement in October 1983 that the department would terminate the project. In November of that year, an agreement was reached by the DOE, TVA, the affected utilities and project stakeholders to begin an orderly termination of the project (Reference 2.3.1-24).
2.3.1-15                                Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report The topography of the site prior to alteration as the result of the CRBRP site preparation is described in the CRBRP Preliminary Safety Analysis Report (PSAR) (Reference 2.3.1-20). A representation of the pre-construction topography and site geology is shown in Figure 2.3.1-17.
The site was characterized as a series of parallel ridges separated by long, narrow valleys extending in a northeast-southwest direction. It was reported that there were no perennial streams on the site; however, after a heavy rain, surface water flowed from the ridges into the valleys and subsequently into the river. It was anticipated that construction of the CRBRP would not significantly alter the drainage pattern of the site (Reference 2.3.1-20).
The topography of the approximately 935-ac CRN Site is shown in Figure 2.3.1-18 as a hillshade map based on a recent Light Detection and Ranging (LiDAR) survey of the site area.
Areas of disturbance as the result of CRBRP site preparation and excavation can be seen by the flattened hillshade areas in Figure 2.3.1-19. The ground surface elevation varies from approximately 740 ft at the Clinch River arm of the Watts Bar Reservoir to over 1100 ft along Chestnut Ridge at the northwestern site boundary. At the CRN Site Powerblock Area (Figure 2.3.1-18), the ground surface elevation is approximately 800 ft with the exception of the CRBRP partially backfilled excavation area.
A more detailed discussion of the regional and local surface water features and geologic descriptions are presented in Subsection 2.3.1.1 and Section 2.6., respectively.
Regional Hydrogeology and Groundwater Aquifers As previously stated, the Valley and Ridge Physiographic Province is characterized by a sequence of folded and faulted, northeast-trending Paleozoic sedimentary rocks that form a series of alternating valleys and ridges. The Valley and Ridge Province in the eastern part of Tennessee is underlain by rocks that are primarily Cambrian and Ordovician in age. Minor Silurian, Devonian, and Mississippian rocks also are present in the province. In general, soluble carbonate rocks and easily eroded shale underlie the valleys in the province, and more erosion-resistant siltstone, sandstone, and some cherty dolomite underlie ridges (Reference 2.3.1-22).
The arrangement of the northeast-trending valleys and ridges and the broad expanse of the Cambrian and the Ordovician rocks are the result of a combination of folding, thrust faulting, and erosion. Compressive forces from the southeast have caused these rocks to yield, first by folding and subsequently by repeatedly breaking along a series of thrust faults (Reference 2.3.1-22). The result of this faulting is that geologic formations can be repeated several times across the faults. In eastern Tennessee, the thrust faults are closely spaced and are more responsible than the folds for the present distribution of the rocks. Following the folding and thrusting, erosion produced the sequence of ridges and valleys on the present land surface.
The principal aquifers in the Valley and Ridge Province consist of carbonate rocks that are Cambrian, Ordovician, and Mississippian in age as shown in Figure 2.3.1-20. These aquifers are typically present in valleys and rarely present on broad, dissected ridges; and underlie more 2.3.1-16                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report than half of the Valley and Ridge Province in Tennessee. Most of the carbonate-rock aquifers are directly connected to sources of recharge, such as rivers or lakes, and solution activity has enlarged the original openings in the carbonate rocks. Other types of rocks in the province can yield large quantities of water to wells where they are fractured or contain solution openings or are directly hydraulically connected to sources of recharge (Reference 2.3.1-22).
Groundwater in aquifers primarily is stored in and moves through fractures, bedding planes, and solution openings in the rocks. These types of openings are secondary features that developed after the rocks were deposited and lithified. Little primary porosity and permeability remain in these rocks after the process of lithification. Some groundwater moves through primary pore spaces between the particles that constitute the alluvium along streams and the residuum of weathered material that overlies most of the rocks in the area (Reference 2.3.1-22).
In the carbonate rocks, the fractures and bedding planes have been enlarged by dissolution of part of the rocks. Slightly acidic water, especially that circulating in the upper 200 to 300 ft of the zone of saturation, dissolves some of the calcite and dolomite that compose the principal aquifers. Most of this dissolution takes place along fractures and bedding planes where the largest volumes of acidic groundwater flow (Reference 2.3.1-22).
Groundwater movement in the Valley and Ridge Province in eastern Tennessee is localized, in part, by the repeating lithology created by thrust faulting and, in part, by streams. Major streams are parallel to the northeast-trending valleys and ridges, and tributary streams are perpendicular to the valleys and ridges. Older rocks (primarily the Conasauga Group and the Rome Formation) have been displaced upward over the top of younger rocks (the Chickamauga and the Knox Groups) along thrust fault planes, forming a repeating sequence of permeable and less permeable hydrogeologic units. The repeating sequence, coupled with the stream network, divides the area into a series of adjacent, isolated, shallow groundwater flow systems. Within these local flow systems, most of the groundwater movement takes place within 300 ft of land surface. In recharge areas, most of the groundwater flows across the strike of the rocks. The water moves from the ridges where the water levels are high toward lower water levels adjacent to major streams that flow parallel to the long axes of the valleys as shown on Figure 2.3.1-21.
Most of the groundwater is discharged directly to local springs or streams, but some of it moves along the strike of the rocks, following highly permeable fractures, bedding planes, and solution zones to finally discharge at more distant springs or streams. Although fracture zones locally are present in the clastic rocks, the highly permeable zones, which are primarily present in the carbonate rocks, act as collectors and conduits for the water (Reference 2.3.1-22).
The most important aquifers in the Valley and Ridge Province in eastern Tennessee are the carbonate rocks underlying the majority of the province. The Knox Group is the most important aquifer in eastern Tennessee. Of particular interest, near the CRN Site, are the Chickamauga Group and the Knox Group (Reference 2.3.1-20). Most of the carbonate-rock aquifers are directly connected to surface water such as rivers and lakes. Other types of rocks can yield large quantities of water to wells where they are fractured, contain solution openings, or are hydraulically connected to a source of recharge (Reference 2.3.1-22).
2.3.1-17                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Secondary porosity features, in the form of bedding planes, fractures, and solution openings, comprise the primary flow pathways in the Valley and Ridge Province, as most rocks in the province have low primary porosity. Regolith layers are composed of clayey soils and saprolite.
Typical conceptual cross sections in the province consist of a storm-flow zone near the surface, a less permeable vadose zone, and a groundwater zone consisting of fractured bedrock with fracture density decreasing with depth (Reference 2.3.1-25). Groundwater flow is generally from recharge areas at high elevation (ridges) to local streams and rivers at lower elevations. The repeating geological sequences described above along with the regional stream network can create a series of adjacent, isolated, shallow groundwater flow systems (Reference 2.3.1-22).
Long-term average annual precipitation is approximately 50 in. in the vicinity of the CRN Site, with an estimated long-term average runoff of 25 to 30 in. (Reference 2.3.1-22). Most of the precipitation that percolates downward becomes groundwater recharge to the shallow aquifers; a small portion enters the deep aquifer. Mixing at depth in carbonate formations have also been studied (Reference 2.3.1-26).
Well yields in the Valley and Ridge Province vary from 1 to 2500 gallons per minute (gpm)
(Reference 2.3.1-22). The largest yields are from wells completed in Ordovician and Cambrian carbonate rocks (e.g., the Knox Group). Wells completed in the middle and lower parts of the Chickamauga Group, the Knox Group, and the upper part of the Conasauga Group have reported yields around 500 gpm in some locations. The median yield of wells completed in the principal aquifers range from about 11 to 350 gpm (Reference 2.3.1-22).
Spring discharges also vary greatly across the Valley and Ridge Province, ranging from about 1 to 5000 gpm, with median discharges from the principal aquifers varying from 20 to 175 gpm (Reference 2.3.1-22). The largest spring discharges issue from limestone formations of the Chickamauga Group; springs from the Knox Group have reported discharges as high as 4000 gpm (Reference 2.3.1-22). Spring discharges can be highly dependent on rainfall with some springs discharging as much as 10 times more water during high precipitation events as compared to periods of little rainfall (Reference 2.3.1-22). Wet-weather perched water tables and intermittent springs have been noted to occur (Reference 2.3.1-25).
Groundwater on the ORR, which is adjacent to the CRN Site, occurs in the unsaturated zone as transient, shallow subsurface storm flow as well as within the deeper saturated zone (Reference 2.3.1-27). An unsaturated zone of variable thickness separates the stormflow zone and water table. Adjacent to surface water features or in valley floors, the water table is found at shallow depths where the stormflow and unsaturated zones are undistinguishable. Along the ridge tops or near high topographic areas, the unsaturated zone is thick, and the water table often lies at considerable depths (approximately 50 to more than 150 ft).
Recharge of the groundwater system is reported to be strongly seasonal at the ORR. The amount of water that recharges the groundwater zone is highly variable depending on the shallow soil characteristics, permeability and degree of regolith fracturing beneath the soil, and the presence of dolines and man-made paved or covered areas. Higher recharge is expected in 2.3.1-18                                    Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report areas of karst hydrogeology such as the Knox aquifer. In the ORR aquitards, groundwater is transmitted through fractures (Reference 2.3.1-27).
The chemical quality of water in the freshwater parts of the Valley and Ridge aquifers is similar for shallow wells and springs. The water is hard, a calcium-magnesium-bicarbonate type, and typically has a dissolved-solids concentration of 170 parts per million (ppm) or less. The ranges of concentrations are thought to be indicators of the depth and rate at which groundwater flows through the carbonate-rock aquifers. In general, the smaller values for a constituent represent water that is moving rapidly along shallow, short flow paths from recharge areas to points of discharge. This water has been in the aquifers for a short time and has accordingly dissolved only small quantities of aquifer material. Conversely, the larger values represent water that is moving more slowly along deep, long flow paths. Such water has been in contact with aquifer minerals for a longer time and thus has had greater opportunity to dissolve the minerals. Also, water that moves into deeper parts of the aquifers can mix with saltwater (brine) that might be present at depth (Reference 2.3.1-22).
The chemical characteristics of the groundwater in the ORR aquitards range from a mixed-cation-bicarbonate water type at shallow depths to a sodium-bicarbonate water type at deeper depths, to sodium-calcium-chloride water type as evidenced from very deep wells.
These chloride-rich waters appear to be a zone of dilution on top of deeper saline sodium-calcium-chloride brines, similar to those encountered within the Conasauga Group at depths greater than 1000 ft in Melton Valley (Reference 2.3.1-26). The Knox aquifer is characterized by a calcium-magnesium-bicarbonate water type.
The hydrogeologic conditions at the CRN Site are similar to those observed at the ORR with the exception of land disturbance areas resulting from earlier site work performed for the CRBRP where excavations and fill material are present.
Local Hydrogeology Description of the local hydrogeology is based on information from the adjacent ORR. The hydrogeology of the ORR is defined by two broad hydrogeologic groups: the Knox aquifer consisting of the Knox Group and the Maynardville Limestone and the ORR aquitards, which include the Chickamauga Group, Conasauga Group, and the Rome Formation (Reference 2.3.1-28). In the vertical dimension, the Knox aquifer and the ORR aquitards are subdivided into:
* The stormflow zone, which is a thin region at the surface where transient, precipitation generated flow accounts for 90 percent or more of the water moving through the subsurface.
* The vadose zone is the unsaturated zone above the water table, which varies in thickness from nearly non-existent along stream channels to greater than 100 ft beneath ridges underlain by the Knox aquifer.
2.3.1-19                                Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* The groundwater zone, which is continuously saturated and is the region where most of the remaining 10 percent of subsurface flow occurs. This zone is typically encountered near the top of bedrock.
* The aquiclude is a zone within the bedrock, within which water movement, if it occurs, probably is on the scale of thousands of years or more.
Chickamauga Group The Middle to Upper Ordovician age Chickamauga Group consists of limestone, shale, and siltstone. In eastern Tennessee it is subdivided into upper, middle, and lower parts. The upper part of the Chickamauga consists of 700 to 1000 ft of limestone and shale. The middle and lower parts, together range in thickness from about 2000 to 6000 ft, consisting of limestones, shales, and siltstone (Reference 2.3.1-20). However, due to thrust faulting, the entire Chickamauga Group sequence is frequently not present (Figure 2.3.1-20) The lower and middle parts of the Chickamauga Group are generally considered to be better aquifers than the upper part (Reference 2.3.1-20). Figure 2.3.1-22 presents the subdivisions of the Chickamauga Group based on the stratigraphy of Bethel Valley in the ORR (Reference 2.3.1-29). The unit designations developed by Stockdale were used during the CRBRP investigation (Reference 2.3.1-30). The formation names shown on the figure are the names used in this investigation.
Groundwater in the Chickamauga Group is largely restricted to fractures which have been enlarged by solutioning. The fracturing of the formation by folding has resulted in a system of cavities which are more or less interconnected. The quality of water in the Chickamauga Group is varied and is influenced by local topography, local land-use patterns, depth below ground surface at which the formation is encountered, and small scale geologic considerations (Reference 2.3.1-20). Many springs occur at the shale-limestone contacts and where solution-widened joints or fractures extend to ground surface in topographic lows. In the lower and middle parts of the Chickamauga limestones, small springs are common, and several can yield more than 450 gpm. Wells in these rocks usually have low yields when located on hills or other topographic highs and have larger yields when located near permanent streams. In the upper part of the Chickamauga limestones, some springs can yield more than 100 gpm (Reference 2.3.1-20).
Knox Group The Upper Cambrian to Lower Ordovician age Knox Group is the most important aquifer in eastern Tennessee. The Knox Group consists of 2000 to 3000 ft thickness of dolomites, limestones, and sandstones. The Knox Group in eastern Tennessee is subdivided into five formations:
* Mascot Dolomite
* Kingsport Formation
* Longview Dolomite 2.3.1-20                                Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* Chepultepec Dolomite
* Copper Ridge Dolomite (Reference 2.3.1-29)
The occurrence of water is controlled by the extent of solution enlargement of fractures (that are the result of ancient folding and faulting). Numerous springs are found in these rocks and the water is generally of good quality. The yield of water to wells ranges from small to large.
Generally the largest fractures and thus greatest well yields are found in the first few hundred ft of formation depth (Reference 2.3.1-20).
Conasauga Group The Middle to Upper Cambrian age Conasauga Group shows lithofacies changes along north-south trending belts from clastics in the west to carbonates in the east. The site area falls within the central area of the group, which exhibits an interfingering of clastic and carbonate deposits. Six formations can be identified within the group:
* Maynardville Limestone
* Nolichucky Shale
* Dismal Gap formation (formerly Maryville Limestone)
* Rogersville Shale
* Friendship formation (formerly Rutledge Limestone)
* Pumpkin Valley Shale The Conasauga Group has an average thickness of approximately 1800 ft in Melton and Bear Creek Valleys. The Maynardville Limestone is associated with the overlying Knox Group and functions as a single hydrologic unit known as the Knox aquifer. The remainder of the group is considered to be an aquitard (Reference 2.3.1-29).
Rome Formation The Early Cambrian age Rome Formation is the oldest bedrock unit exposed in the site area.
The Rome Formation consists of mixed siliciclastic and carbonate rocks. The lithologies represented in the formation include sandstone, siltstone, and shale with dolomite and dolomitic sandstone intervals. Studies have suggested that the true stratigraphic thickness of this formation is between 300 and 400 ft. This formation is considered to be an aquitard (Reference 2.3.1-29).
Unconsolidated Deposits The unconsolidated deposits in the CRN Site area typically consist of four types: residuum, colluvium, alluvium, and anthropogenic materials.
2.3.1-21                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Residuum The residuum is composed of the remains of bedrock weathering. In the site area bedrock weathers to a clayey residual soil, which locally contains chert gravel. During the CRBRP investigation, the thickness of the residuum was found to vary from 1 to 78 ft, depending on the type of underlying bedrock (Reference 2.3.1-20).
Colluvium Colluvium is an unconsolidated deposit sometimes found at the toe of a slope, and it represents material that has been moved by gravity. Colluvial deposits are generally identified by a lack of residual rock structure (bedding or joints) with disoriented rock fragments. This material tends to have more rock fragments than either residuum or alluvium. Colluvial deposits may be reworked by surface water action resulting in a hybrid colluvium-alluvium mixture (Reference 2.3.1-29).
Alluvium The alluvium includes deposits by the Clinch River and smaller tributary streams. During the CRBRP investigation, alluvial terrace deposits were identified on the site. These deposits consisted of silty clay with thin layers of rounded quartz, chert, and quartzite gravel. Additionally a sand and clay alluvial layer was found to occur in the Clinch River floodplain, with a thickness of approximately 32 ft (Reference 2.3.1-20).
Anthropogenic Materials Anthropogenic materials are primarily associated with artificial backfill. These materials include overburden and shot-rock (i.e., rock that has been excavated by blasting). Materials were excavated during site preparation for the CRBRP. These materials were moved and placed to facilitate laydown and parking area construction and to implement the site redress plan, when the project was canceled (Reference 2.3.1-24).
Summary of Local Hydrogeology Figure 2.3.1-23 shows the vertical relationship of the bedrock subdivisions for the Knox aquifer and the ORR aquitards. The figure indicates that fracture frequency decreases and the concentrations of sodium and chloride increase in the groundwater with increasing depth.
Numerous groundwater investigations have been performed at the ORR providing hydrogeologic property data for the bedrock units. Testing has included slug tests, packer tests, aquifer pumping tests, and tracer tests (Appendix 2.3-A). Figure 2.3.1-24 summarizes the hydraulic conductivity test results (box and whisker plot and hydraulic conductivity versus depth) by geologic formation and by depth below ground surface. The hydraulic conductivity by depth graph suggests that at approximately 100 ft below ground surface (bgs), hydraulic conductivities decrease with depth, although this trend is less obvious in the Knox aquifer, since both fracturing and solutioning are active in this unit. Figure 2.3.1-25 summarizes the results of 2.3.1-22                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report selected aquifer pumping tests performed on the ORR (presented in Appendix 2.3-A). The statistics presented on the figure indicate a geometric mean transmissivity of 32.5 feet squared per day (ft2/d) and a storage coefficient of 5.9 x 10-4 ft2/d for the Conasauga Group tests.
Additional hydrogeologic parameters for the stormflow and groundwater zones on the ORR are summarized on Table 2.3.1-2. The information presented in Table 2.3.1-2 suggests the transmissivity values for the ORR aquitards are approximately one order of magnitude less than those of the Knox aquifer.
Site Specific Hydrogeology Site specific hydrogeology has been investigated during the CRBRP licensing effort and preparation for the early site permit application.
CRBRP Investigation As part of the licensing activities for the CRBRP, the site was investigated by drilling 129 borings, installing 37 observation wells, installing 11 piezometers, and performing 117 bedrock packer permeability tests in boreholes. The investigation also included collection of groundwater level data and performing a survey of local groundwater users (Reference 2.3.1-20). Abandoned wells from the CRBRP were identified on site. The identified CRBRP wells will be evaluated for closure in accordance with applicable TVA and TDEC requirements.
The CRBRP SI identified four bedrock joint set orientations at the site:
* N52&deg;E 37&deg;SE
* N52&deg;E 58&deg;NW
* N25&deg;W 80&deg;SW
* N65&deg;W 75&deg;NE (Reference 2.3.1-20)
The predominant joint set is oriented N52&deg;E 37&deg;SE, which corresponds with the bedding plane partings in bedrock. The N52&deg;E 58&deg;NW joint set has a joint spacing of between one and six ft (Reference 2.3.1-20).
The results of the CRBRP packer hydraulic conductivity tests are shown on Figure 2.3.1-26 (and presented in Appendix 2.3-B), includes summary plots (box and whisker and hydraulic conductivity vs. depth) of the packer test results. The results can be classified in three groups:
the Chickamauga long interval tests (test section length 40 ft and greater), the Chickamauga discrete interval tests (test section length less than 40 ft), and the Knox Group tests. The CRBRP packer-test-derived hydraulic conductivity results are similar to hydraulic conductivity test results from the ORR. Both sets of results indicate a decreasing trend in hydraulic conductivity at depths greater than approximately 100 ft bgs.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Water level measurements on the site indicated fluctuation in water levels as much as 20 ft.
Maximum water levels were observed in January and February and minimum water levels were observed in October and November. Movement of groundwater is described as generally from topographically high areas to topographic lows; however, this pattern is modulated by the extent of weathering in the bedrock. Ultimately, the Clinch River acts as a sink for site groundwater flow. The investigation concluded that major ridges on the site may be regarded as approximate locations of groundwater divides (Reference 2.3.1-20).
CRN Site Investigation The CRN Site field investigation included drilling 82 borings, installing 3 test pits, installing 44 wells, and performing in-situ/ex-situ tests on soil, rock, and groundwater. Groundwater characterization activities included monitoring groundwater levels and performing packer tests in boreholes, slug tests in monitoring wells, an aquifer pumping test, and groundwater geochemical sampling. Groundwater level monitoring is discussed in Subsections 2.3.1.2.2.2 and 2.3.1.2.2.3, aquifer properties are discussed in Subsection 2.3.1.2.2.4, and geochemical results are discussed in Subsection 2.3.3.2.
The locations of observation wells installed during this investigation are shown on Figure 2.3.1-18 and well installation details are provided on Table 2.3.1-3. The figure and table include permanent observation wells (OW prefix) and supplemental wells (PT-OW and PT-PW prefixes) installed for the aquifer pumping test. Well suffixes of U, L, and D were assigned to wells to designate the upper, lower, and deeper monitoring zones respectively. The screened depth intervals for the site observation wells for the upper monitoring zone range from 15 to 105 ft bgs, the lower monitoring zone range from 89 to 178 ft bgs, and the deeper monitoring zone range from 176 to 297 ft bgs.
A three-well cluster was installed east of the OW-101 well cluster, at boring location MP-422 (OW-422 U, L and D). During well completion, groundwater contamination was observed in OW-422L, and TVA notified TDEC and provided it with results of well sampling. The contamination was determined to be non-radiological petroleum products. Due to the contamination in OW-422L, this well cluster (OW-422 U, L and D) was not developed; however, it remains in place, locked and under TVA control. TVA has no plans to perform any additional work in the location, and TDEC will make a determination regarding the disposition of the well.
Because the wells were not developed and monitoring of water levels in these wells was not performed, the OW-422 well series is not included in the discussion of site observation wells.
Well clusters OW-428 and OW-429 (installed north and south of the OW-422 cluster) were installed to provide replacement geological/groundwater data.
Additional as-built information for the site wells is presented in the Data Report for Geotechnical Exploration and Testing (Reference 2.3.1-21). All permanent observation wells at the CRN Site were sampled after well development and no evidence of petroleum products was observed in the wells. The contamination seems to be restricted to the immediate well OW-422 area since no evidence of petroleum products were observed before and after the 72-hr 2.3.1-24                                    Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report pumping test conducted near the OW-423 U, L, and D well cluster (up dip of OW-422L). The hydrogeology of the CRN Site is expected to be similar to the hydrogeology of the ORR as a result of the sites physical proximity and similarity in geology. The primary differences are in the storm-flow and vadose zones at the CRN Site. The extensive excavation and reworking of unconsolidated and weathered bedrock materials associated with the CRBRP site preparation has either significantly modified or obliterated these zones at the CRN Site.
Groundwater Sources and Sinks This subsection describes the regional, local, and site-specific discharge and recharge areas, mechanisms, and characteristics of the different aquifer units.
Groundwater Discharge Natural discharge of the Valley and Ridge Province aquifers is primarily through streams, rivers, springs and evapotranspiration. In the site area, the Clinch River acts as a sink to which all groundwater at the site migrates (Reference 2.3.1-20).
Studies performed by the DOE for the Melton Valley offsite monitoring system, which is located approximately two miles east of the CRN Site, investigated the groundwater flow relationship with the Clinch River (Reference 2.3.1-31). Figure 2.3.1-27 presents a section through the river showing the head distribution. This head distribution suggests discharge to the Clinch River from the surrounding groundwater system.
Groundwater Recharge Groundwater recharge is derived primarily from precipitation. Although periodic recharge from the Clinch River during high stages of the river may also be occurring, this is not considered to represent a significant part of the recharge to the aquifer. Recharge is most effective in those areas where the overburden soils are thin and permeable. Recharge may also occur through sinkholes that penetrate relatively thick and impervious formations (Reference 2.3.1-20).
2.3.1.2.2    Groundwater Sources This subsection contains information pertaining to sole-source aquifers, groundwater flow directions and hydraulic gradients, seasonal and long-term variations of groundwater levels, hydraulic conductivity and effective porosity of the geologic formations. This information has been organized into five subcategories: (1) identification of sole source aquifers, (2) groundwater flow directions, (3) temporal groundwater trends, (4) aquifer properties, and (5) hydrogeochemical characteristics.
Sole Source Aquifers A sole-source aquifer is defined as the sole or principal source of drinking water that supplies 50 percent or more of drinking water for an area, with no reasonable available alternative sources 2.3.1-25                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report should the aquifer becomes contaminated. Figure 2.3.1-28 shows the location of sole-source aquifers in U.S. Environmental Protection Agency (EPA) Region 4, which encompasses Tennessee. Because surface water is abundant in the area, the EPAs Sole Source Aquifer Program has not identified any sole source aquifers in Tennessee as shown in Figure 2.3.1-28 (Reference 2.3.1-32). The identified sole-source aquifers in EPA Region 4 are beyond the boundaries of the local and regional hydrogeologic systems associated with the CRN Site.
Therefore, the CRN Site will not impact any identified sole-source aquifer.
Temporal Groundwater Trends The USGS maintains a network of observation wells in Tennessee to monitor trends in water levels. The closest permanent observation well is approximately 48 mi southeast of the CRN Site as shown on Figure 2.3.1-29 (Reference 2.3.1-33). This observation well is screened in the Great Smoky Group aquifer and is approximately 220 ft deep. The well indicates typical annual fluctuations of between 1 and 3 ft. The USGS also presents data from a manual water level measurement well located approximately 0.5 mi east of the CRN Site as shown on Figure 2.3.1-30 (Reference 2.3.1-34). This well is screened in the Valley and Ridge aquifer and is approximately 610 ft deep. The period of record is only approximately 3 months; however the hydrograph shows an approximate 5 ft range of water levels fluctuations. Neither of these USGS wells monitor the hydrogeologic units relevant to the site.
During the CRBRP investigation, periodic water level measurements were made in the site observation wells and piezometers. Examination of these measurements suggests an annual fluctuation of 10 to 25 ft with maximum water levels occurring in January and February and minimum water levels occurring in October and November (Reference 2.3.1-20).
The CRN Site hydrogeologic characterization program consisted of two years of groundwater level measurements in site observation wells. This included periodic manual measurements in all wells (except the OW-422 well cluster), beginning September 23, 2013, and continuous measurements from a recording pressure transducer in the following wells, beginning on November 23 and 24, 2013:
* OW-101
* OW-202
* OW-409
* OW-417
* OW-423 Figure 2.3.1.-31 presents hydrographs for the site well clusters, along with Clinch River (Watts Bar Reservoir) stage and site precipitation data for comparison. Water level responses from wells OW-101D, OW-409U, OW-416U/L, OW-420L, and OW-421D show correspondence to the Watts Bar Reservoir stage with periodic deviations that appear to be associated with 2.3.1-26                                Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report precipitation events. All of the site wells show a response to precipitation events, with OW-417L and OW-421U showing the most subdued response to precipitation. The location of well clusters OW-417 and OW-421 in proximity to the Clinch River may explain the subdued responses in these wells.
Observation wells OW-202L, OW-421L, OW-421D, OW-428U, OW-428L, and OW-428D show water level artifacts from well installation, development, and water sampling; these wells are excluded for the purpose of characterizing the range of fluctuation. The range of water level elevation fluctuations in the site observation wells was from approximately 1ft (OW-421U) to 25 ft (OW-409U). These fluctuations appear to be associated with precipitation events. The large magnitude of fluctuation at OW-409U may be further indication that this well is located in a recharge area.
Groundwater Flow Directions Groundwater flow directions in the ORR are generally characterized as from the ridge tops to drainages within the adjacent valley or as a subdued replica of topography. Figure 2.3.1-32 presents conceptual block flow diagrams for Bethel Valley, which has similar geology as the CRN Site (Reference 2.3.1-35). The figure indicates localized influences such as springs, discontinuity orientations (fractures and bedding planes), man-made features (pipelines, tank farms, and building basements), and solution features have an impact on flow directions.
Groundwater flow directions were evaluated during the CRBRP PSAR by preparing two groundwater contour maps, one for December 24, 1973 and one for January 2, 1974 (Reference 2.3.1-20). Both maps indicate a general flow direction toward the southeast or southwest in the area of the proposed nuclear island. An average hydraulic gradient of approximately 0.007 feet per foot (ft/ft) is reported for the two maps (Reference 2.3.1-20). It should be noted that these maps were prepared using water level measurements from observation wells with long screened intervals and thus the equipotentials represent a vertically averaged head.
The CRN Site investigation included synoptic measurements of groundwater levels in the site observation wells. These measurements were used to prepare maximum potentiometric surface maps for the site. The maximum potentiometric surface maps used the maximum groundwater level elevation at each well cluster. Figures 2.3.1-33 through 2.3.1-42 present the potentiometric surface maps. The maps indicate a southwest to southeast flow direction in the area of the proposed CRN Site Powerblock Area. Hydraulic gradients were measured along selected flow lines on each figure. Table 2.4.12-8 in the Site Safety Analysis Report (SSAR) presents the horizontal hydraulic gradients for the ten potentiometric surface maps. The horizontal hydraulic gradients range from 0.03 to 0.12 ft/ft. Horizontal gradients were also evaluated using just the upper site observation wells for the eight quarters (December 2013, March 2014, May 2014, August 2014, November 2014, February 2015, May 2015, and August 2015), resulting in horizontal gradients ranging from 0.05 to 0.17 ft/ft. For comparison the average hydraulic gradient between the maximum water level at OW-101U and OW-202U and the Clinch River 2.3.1-27                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report arm of the Watts Bar Reservoir is 0.05 ft/ft. This is derived based on a shortest distance of 1400 ft from the power block area to the edge of the Clinch River arm of the Watts Bar Reservoir; lowest stage of the reservoir at 735 ft NAVD88 (during the monitoring period); and the maximum water levels at OW-101U and OW-202U of 798.99 and 800.30 ft NAVD88. Due to the complexity of the subsurface hydrogeologic conditions at the CRN Site, the maximum potentiometric groundwater elevation at each well cluster is used, representing a single hydrogeological unit. Given that the U, L, and D wells generally screened within different hydrogeologic units, the maximum potentiometric surface maps do not represent a true potentiometric surface. These maps can, however, be considered bounding in terms of depicting the maximum groundwater elevations at the site.
Vertical hydraulic gradients were determined at each well cluster to evaluate the potential for vertical movement in the subsurface. The average vertical hydraulic gradients range from -0.69 to 1.03 ft/ft (Appendix 2.3-C). A negative vertical hydraulic gradient indicates an upward flow potential and a positive one indicates a downward flow potential. The upward flow potential would suggest groundwater discharge and the downward flow potential would suggest groundwater recharge. A majority of the wells with upward flow potential are located on the western and eastern sides of the site suggesting discharge towards incised site drainage features or to the Clinch River. The exception to this is well cluster OW-409U/L, which is located near the center of the site. This cluster may be indicating groundwater discharge to the adjacent CRBRP excavation. The cluster with the highest downward flow potential is OW-429U/L, suggesting a recharge area. Figure 2.3.1-43 represents the spatial variation of equipotential in the vertical plane in a cross-section along the strike of the bedding plane based on June 13, 2014 observations. Groundwater discharges from the higher equipotential area (at OW-202) to the Clinch River arm of the Watts Bar Reservoir, with OW-202 at the center of the CRS peninsula as a likely location of the groundwater divide.
Aquifer Properties Aquifer properties at the CRN Site were determined by in-situ testing and from laboratory testing of rock core and soil samples collected during the investigation. The following sections present the results of this testing.
Hydrogeological Parameters The primary hydrogeological properties of interest at the site are the hydraulic conductivity and effective porosity of the bedrock. Hydraulic conductivity was evaluated qualitatively through fracture frequency analysis and quantitatively through in-situ testing. The in-situ tests performed were borehole packer tests, well slug tests, and an aquifer pumping test. Effective porosity is based on a series of studies performed on the ORR.
2.3.1-28                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Fracture Frequency Analysis Fracture frequency analysis was performed by plotting the open fractures identified on the acoustic televiewer borehole geophysical logs. Figure 2.3.1-44 presents the resulting frequency distribution histogram. The histogram shows three general areas: 1) from elevation 812 to 712 ft NAVD 88, a pervasively fractured zone; 2) from elevation 712 to 612 ft NAVD 88, a moderately fractured zone; and 3) from 612 to 487 ft NAVD 88, a slightly fractured zone. It should be noted that the upper elevation of the pervasively fractured zone is somewhat biased, since most boreholes were cased into the top of bedrock prior to performing the geophysical surveys, and thus the number of open fractures at the top of rock is not accurately represented and are likely under-reported. Figure 2.3.1-45 presents an example geophysical log demonstrating this bias.
The fracture distribution identified at the CRN Site is consistent with observations at the ORR. In nearby Melton and Bethel Valleys, the transition from fractured to less fractured bedrock occurs at approximately 150 ft bgs (Reference 2.3.1-28). Figure 2.3.1-24, which is a plot of ORR hydraulic conductivity test results, indicates a generalized decrease in hydraulic conductivity at approximately 100 ft bgs.
Borehole Packer Tests A borehole packer test is a constant head test of an isolated interval in a borehole to determine the hydraulic conductivity. For the CRN Site investigation, a double packer arrangement was used to isolate the test zone. A total of 41 packer tests were performed in 12 open boreholes during the field investigation. Of these tests, 5 exhibited evidence of flow by-passing around the packers and 14 had flow rates less than the quantifiable rate for the test, and thus were not analyzed. Table 2.3.1-5 presents the test results.
The tests were performed and interpreted using USACE method 381-80 (Reference 2.3.1-36).
The borehole packer test results were arranged by geologic unit and are presented in a box and whisker plot on Figure 2.3.1-46. Summary statistics for these tests are included on the figure.
The results were also compared with the packer tests performed during the CRBRP investigation as shown on Figure 2.3.1-46. In general the two data sets agree; however, the CRBRP Chickamauga long interval and CRBRP Knox tests exhibit an order of magnitude, or more, lower range of values. This may in part be due to the deeper test intervals selected during the CRBRP investigation. The upper range of values is similar for both data sets.
The CRN packer results were plotted versus depth below ground surface as shown on Figure 2.3.1-47. The results show a similar pattern as the CRBRP tests (Figure 2.3.1-26) and the ORR hydraulic conductivity tests (Figure 2.3.1-24). The hydraulic conductivities decrease below 150 ft bgs. This is most probably the result of the decreased frequency of open fractures below this depth.
2.3.1-29                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Well Slug Tests The slug test method involves creating a sudden water level displacement in the well and observing the water level change as it returns to the pre-test level. Slug tests were performed in selected site observation wells. Observation wells excluded from testing include OW-202U, OW-402U, and OW-429L because of low water levels in the wells and OW-428D because the well was still recovering from development activities. Slug tests used either a solid slug or pneumatic slug to induce the water level change. Two tests were performed in each well, one where the water level was raised in the well and allowed to fall back to the pre-test level (falling head) and one test where the water level in the well was lowered and allowed to rise back to the pre-test level (rising head). A recording pressure transducer was placed in the well to monitor the water level changes. Slug test results were entered into the AQTESOLV (HydroSOLVE 2007) computer program and the Bouwer and Rice method was used for interpretation (Reference 2.3.1-37; Reference 2.3.1-38).
The slug test solution is a porous medium method and is applied to fractured bedrock. Porous medium slug test method results were compared with discrete fracture interval method results (Reference 2.3.1-39). Their comparison found that using porous medium methods, the results were on the same order of magnitude as the results for the discrete fracture interval methods. A porous medium assumption is appropriate in highly fractured materials and where fluid exchange between the fractures and the rock matrix is either very limited or very rapid (Reference 2.3.1-40). The observation wells were located in the most fractured intervals identified in the borehole logs. Information from the ORR on Table 2.3.1-2 indicates that a matrix hydraulic conductivity of 2.8 x 10-7 ft/d is representative of the ORR Aquitards, which includes the Chickamauga Group. This matrix hydraulic conductivity suggests that the rock matrix is not contributing significantly to flow. These studies suggest that the use of the porous medium assumption is reasonable for the CRN Site tests.
Table 2.3.1-6 presents the results of the slug test interpretations. Examination of the table indicates that the test results from four wells (OW-202L, OW-401D, OW-415U, and OW-421D) could not be interpreted. Additionally, the results from five wells (OW-409U, OW-415L, OW-421L, OW-423D, and OW-429U) had one test (falling or rising head) that could not be interpreted. For those wells with one test, the average hydraulic conductivity is equivalent to the results of the test (falling or rising head) that could be interpreted.
Figure 2.3.1-48 presents the slug test results graphically. The figure includes a box and whisker plot of hydraulic conductivity by observation well monitoring zone and a scatter plot of hydraulic conductivity versus depth below ground surface. The box and whisker plot indicates that the hydraulic conductivities in the upper and lower zones are similar, while those in the deep zone are lower. The scatter plot of hydraulic conductivity versus depth below ground surface in general shows a pattern of decreasing range in hydraulic conductivity with depth similar to plots in Figure 2.3.1-26 and Figure 2.3.1-47. Figure 2.3.1-49 is a box and whisker plot comparing the slug test results with the CRN Site packer test results for the two major geologic units (Chickamauga Group and Knox Group) present at the site. The figure indicates a similar central 2.3.1-30                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report tendency in the results of both tests, but the slug tests have a much broader range of values.
The breadth of this range may be due to the longer test intervals for the slug tests as compared to the packer test intervals.
Aquifer Pumping Test An aquifer pumping test was performed at the CRN Site. The aquifer pumping test array consisted of a pumping well (PT-PW) and nine proximal observation wells (PT-OW-U1, PT-OW-L1, PT-OW-U2, PT-OW-L2, PT-OW-U3, PT-OW-L3, OW-423U, OW-423L, and OW-423D) as shown on Figure 2.3.1-18. The installation completion data for these wells are included on Table 2.3.1-3. The pumping well was screened in the Fleanor and Eidson members of the Lincolnshire formation and the Blackford formation. The upper zone observation wells were screened in the Eidson member of the Lincolnshire formation and the lower and deep zone observation wells were screened in the Blackford formation. The aquifer thickness was taken to be 155 ft, which represents the difference between the static water level in the pumping well and the bottom elevation of the primary flow zone. (A review of the geologic log cores did not identify an overlying confining bed; it is presumed that leakage is derived from an underlying confining bed.) A constant rate pumping test was performed in the pumping well for a period of 72 hr with an average pumping rate of 14.5 gpm.
Pumping and observation well responses were reviewed and diagnostic plots of each well were prepared. Based on a review of the observation well water level responses, a portion of the observation wells were discarded from further analysis, because they were outside the radius of influence of the pumping well or they were completed in different hydrogeologic unit.
Interpretation of the diagnostic plots for the results that were retained indicated that a leaky aquifer model most accurately represents the observed response. The water level response and pumping rate data were entered into the AQTESOLV (HydroSOLVE 2007) computer program for analysis (Reference 2.3.1-38). The solution method used was that presented in Hantush and Jacob (Reference 2.3.1-41).
Table 2.3.1-7 presents the results of the constant rate pumping test interpretation. Examination of the results suggests the maximum transmissivity and hydraulic conductivity is observed at OW-423L, which is oriented with the N52&deg;E strike of the bedding planes relative to the pumping well. The observation wells (PT-OW-U2 and PT-OW-L2) oriented perpendicular (N38&deg;W) to the strike of the bedding planes show approximately an order of magnitude lower transmissivity and hydraulic conductivity. Comparison of the results of this aquifer pumping test with tests performed on the ORR, as shown on Figure 2.3.1-25, indicates that the transmissivities are within the same range, but the storage coefficient values have a greater range for the CRN Site aquifer pumping test.
Effective Porosity Table 2.3.1-8 summarizes the results of petrophysical testing of rock samples to determine the effective porosity of rock from the Conasauga and Knox Groups on the ORR. The test methods 2.3.1-31                                  Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report used include helium, mercury, and immersion-saturation porosimetry. The authors indicate that the immersion-saturation method would produce the results that most accurately approach the true value of effective porosity. The average effective porosity of bedrock determined from these tests is approximately 4 percent.
Geotechnical Parameters During the CRN Site investigation, soil and rock samples were collected and tested.
Interpretation of the test results has resulted in best estimates of properties of the different materials that are present or may be present in the future at the site. Table 2.3.1-9 summarizes the estimates of parameters important to radionuclide transport.
Summary of Aquifer Properties Hydrogeologic testing information for the CRN Site area were obtained from 1) published bedrock aquifer testing from the ORR area; 2) CRBRP investigation packer tests; 3) CRN Site packer tests; 4) CRN Site slug tests: and 5) the CRN Site aquifer pumping test. The Conasauga Group, Knox Group, and the Chickamauga Group are the three major geologic strata in which the hydrogeologic testing were undertaken. Evaluation of these results suggests that hydraulic conductivity, in the bedrock, generally decreases with depth irrespective of the lithology.
Additional petrophysical testing, such as bulk density and porosity testing have been performed at the ORR and at the site. The results of these tests show generally uniform properties in the bedrock units.
Hydrogeochemical Characteristics Site specific groundwater chemical data was collected from selected CRN onsite observation wells and compared to existing hydrogeochemical data from the surrounding area. Results and evaluation of these data sets are presented in Subsection 2.3.3.2.
2.3.1.2.3  Subsurface Groundwater Pathways The CRN Site is surrounded on three sides by the Clinch River arm of the Watts Bar Reservoir, which is interpreted to be the discharge area for site groundwater. The most likely pathway for groundwater flow is recharge in the upland areas of the site with discharge to the Clinch River arm of the Watts Bar Reservoir. An alternate groundwater pathway is recharge in the upland areas with seepage to onsite drainages and surface water discharge into the Clinch River arm of the Watts Bar Reservoir. It is very unlikely that there is shallow groundwater flow underneath the Clinch River arm of the Watts Bar Reservoir and exposure to water users on the opposite side of the Reservoir. This conclusion is based on 1) the absence of cavities and contiguous fractures below elevation 720 ft, 2) the head relationships observed at the Melton Valley Exit Pathway monitoring wells (Reference 2.3.1-31), and 3) the observed vertical hydraulic gradients demonstrate that the Clinch River arm of the Watts Bar Reservoir acts as a hydrologic sink. This is further supported by the following observations:
2.3.1-32                                    Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* There is no evidence of contiguous cavities or fractures originating from the power block area and extending below the Clinch River arm of the Watts Bar Reservoir, based on geologic core analysis from subsurface investigations;
* The CRBRP excavation, completed to an elevation of 714 ft NGVD29 and 6 ft below the invert elevation of the Clinch River arm of the Watts Bar Reservoir, showed no evidence of any continuous groundwater flow; this is likely due to an absence of cavities and continuous fractures below elevation 720 ft;
* Only 5 percent of the observed cavities fall below elevation 718.4 ft with the average elevation of observed cavities being 782.6 ft; and
* An analysis of site-specific geologic core analysis, fracture frequency analysis, and groundwater vertical gradient data provides no evidence supporting a pathway for radionuclide transport occurring underneath the Clinch River arm of the Watts Bar Reservoir within the shallow groundwater system.
Advective Transport Advective transport in groundwater is assumed to occur in an equivalent porous medium. This assumption is based on the findings of the aquifer pumping test and other hydraulic conductivity tests and is restricted to the shallow groundwater system. In the deeper groundwater system, that is not pervasively fractured, discrete fractures control the movement of groundwater.
However, as discussed in Subsection 2.3.1.2.1.2 and shown on Figure 2.3.1-23, greater than 90 percent of groundwater flow occurs in the shallow zone.
The porous medium flow is represented by Darcys law, when written in terms of linear velocity is:
v = K/ne x dh/dl Where:
v      =      linear groundwater velocity [L/T]
K      =      hydraulic conductivity [L/T]
ne      =      effective porosity dh/dl  =      hydraulic gradient (change in head over change in length)
(Reference 2.3.1-42)
The travel time (T) is determined by dividing the distance to the receptor (D) (Clinch River arm of the Watts Bar Reservoir) by the linear groundwater velocity (v):
T = D/v 2.3.1-33                                Revision 2
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Table 2.3.1-10 presents a summary of these parameters and the linear velocity and travel time determined from these parameters. Using the representative parameter values, a travel time of 359 days is determined (Table 2.3.1-10).

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3.2    Water Use This subsection describes surface water and groundwater uses in the vicinity of the Clinch River Nuclear (CRN) Site which can affect or be affected by the construction and operation of two or more small modular reactors (SMRs). Information provided in this subsection includes descriptions of the types of consumptive and non-consumptive water uses, identification of water use withdrawal and discharge locations, and qualification of water withdrawals and returns. In addition, a detailed assessment of local area facility water use is discussed in this subsection.
2.3.2.1    Surface Water To evaluate surface water availability for the Clinch River (CR) SMR Project, Tennessee Valley Authority (TVA) conducted a Regional Surface Water Use Study (Reference 2.3.2-1).
2.3.2.1.1    Basin-wide Surface Water Use Total surface water withdrawals for the Tennessee River watershed during 2010 were estimated to average 11,747 million gallons per day (mgd). The return flow was estimated to be 11,480 mgd, which represents 96.1 percent of the water withdrawn. The net water demand, which is the difference between the withdrawals and the returns, is a measure of consumptive use.
Consumptive use is water that evaporates, transpires, or is consumed by humans, livestock, or crops. The net water demand in 2010 was 471 mgd, or 3.9 percent of the total withdrawals.
(Reference 2.3.2-1)
Of the 11,747 mgd of surface water withdrawn from the Tennessee River system in 2010, thermoelectric power withdrawals were an estimated 10,046 mgd; industrial withdrawals were 1116 mgd; public supply withdrawals were 558 mgd; and irrigation withdrawals were 27 mgd.
(Reference 2.3.2-1)
In 2010, net water demand was 52 mgd for thermoelectric, 75 mgd for industrial, 310 mgd for public supply, and 34 mgd for irrigation. By 2035, overall total water withdrawals are projected to decline approximately 21 percent to 9449 mgd. By category, water withdrawals are projected to increase as follows: industrial withdrawals increase 31 percent to 1502 mgd, public supply withdrawals increase 30 percent to 938 mgd, and irrigation withdrawals increase 35 percent to 46 mgd. Thermoelectric water withdrawal is expected to decline 31 percent to 6963 mgd, reflecting a change in both generating and cooling technologies for power plants. (Reference 2.3.2-1)
Table 2.3.2-1 shows historical off-stream water use in the Tennessee River watershed from 1995 to 2010 and projected water use to 2035. Total water use peaked in 2005 and has decreased since then, mostly due to decline in thermoelectric water use. Industrial and irrigation use has changed little from 1995 to 2010, but public supply has increased steadily, closely following population growth.
2.3.2-1                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3.2.1.2  Water Use Regulation The U.S. Environmental Protection Agency (EPA) has promulgated regulations that implement Section 316(b) of the Clean Water Act (CWA) for new and existing electric power producing facilities. Subpart I of Title 40 of the Code of Federal Regulations (40 CFR) Part 125 describes requirements applicable to cooling water intake structures for new facilities. Under the definitions in 40 CFR 125.83, the Watts Bar Reservoir would be considered a lake or reservoir, because it has a residence time greater than 7 days.
The impacts of the cooling water intake structures at the facility are regulated by the Tennessee Department of Environment and Conservation (TDEC), under Section 316(b) of the Federal Water Pollution Control Act (also known as the CWA), through limitations specified in the National Pollutant Discharge Elimination System (NPDES) permit for the facility. These CWA 316(b) requirements seek to protect water quality from the potential adverse impacts of water withdrawals through intake structures. Separately, TDEC implements state water registration requirements to gather information that helps the management of water resources.
2.3.2.1.3  Surface Water Use in the CRN Site Vicinity For the Regional Surface Water Use Study, TVAs 2010 Water Use database was queried for the seven-county area surrounding the CRN Site (Reference 2.3.2-1).. The results for water withdrawal are summarized in Table 2.3.2-2. Table 2.3.2-3 contains the individual data records from the query for withdrawals and Figure 2.3.2-1 shows the locations of the withdrawals.
As shown in Table 2.3.2-2, total 2010 withdrawal was 1478.91 mgd. Thermoelectric water use (1366.17 mgd) was by far the highest usage due to withdrawals for Bull Run, Kingston, and Watts Bar power plants. Public supply was the second highest water use (102.62 mgd).
Of the water intakes listed in Table 2.3.2-3, only the Oak Ridge Bear Creek Road facility has a Surface Water Protection Area which includes the CRN Site. Presently, Oak Ridge has plans to close down the Bear Creek Road facility.
TVAs reservoir operating policy was designed to meet the off-stream water needs of the Tennessee Valley until the year 2030. The forecast of 2030 water needs was based on a water use estimate prepared using year 2000 data. The estimates used to develop the reservoir operating policy were a total withdrawal of 13,990 mgd with a return of 13,010 mgd with a net water demand of 980 mgd. The current watershed projection of water demand for 2035 indicates a total withdrawal of 9449 mgd with a return of 8737 mgd for a net water demand of 712 mgd. (Reference 2.3.2-1)
There is no hydroelectric power generation in the immediate vicinity of the CRN Site; however, the Melton Hill, Watts Bar, and Norris dams include hydroelectric generation plants. Both dams are multipurpose dams with operations that also include maintaining navigation channels, flood 2.3.2-2                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report control, recreational opportunities, fisheries and aquatic habitat, and water quality. (Reference 2.3.2-2; Reference 2.3.2-3; Reference 2.3.2-4)
The Clinch River arm of Watts Bar Reservoir is host to various recreational activities, including canoeing, kayaking, boating, and fishing (Reference 2.3.2-5). Both commercial and recreational boating are available in the vicinity of the CRN Site. Recreational boat access and fishing opportunities are provided at the area boat ramps and public parks (Reference 2.3.2-6). These recreational activities are discussed in further detail in Subsection 2.5.2.5.
2.3.2.1.4    Surface Water Use for the Proposed SMR The use of water for the proposed SMR is described in Section 3.3.
2.3.2.2      Groundwater Use This section contains a description of the historical, current, and projected groundwater use at and in the vicinity of the CRN Site. Sole source aquifers within the region are also identified and discussed.
As discussed in Subsection 2.3.1.2.1.2, the principal aquifers in the Valley and Ridge Province consist of the carbonate rocks. Other types of rocks in the province can yield large quantities of water to wells where they are fractured, contain solution openings, or are directly hydraulically connected to sources of recharge (Reference 2.3.2-7).
Well yields in the Valley and Ridge Province vary from 1 to 2500 gallons per minute (gpm). The largest yields are from wells completed in Ordovician and Cambrian carbonate rocks (e.g., the Knox Group). The median yield of wells completed in the principal aquifers range from about 11 to 350 gpm (Reference 2.3.2-7).
Spring discharges also vary greatly across the Valley and Ridge Province, ranging from about 1 to 5000 gpm, with median discharges from the principal aquifers varying from 20 to 175 gpm.
Spring discharges can be highly dependent on rainfall with some springs discharging as much as 10 times more water during high precipitation events as compared to periods of little rainfall (Reference 2.3.2-7). Wet-weather perched water tables and intermittent springs have been noted to occur.
Because surface water is abundant in the region, the EPAs Sole Source Aquifer Program has not identified any sole source aquifers in Tennessee (Subsection 2.3.1.2). A sole-source aquifer is defined as the sole or principal source of drinking water that supplies 50 percent or more of drinking water for an area, with no reasonable available alternative sources should the aquifer becomes contaminated. The identified sole-source aquifers in EPA Region 4 are beyond the boundaries of the local and regional hydrogeologic systems associated with the CRN Site.
Therefore, the CRN Site will not impact any identified sole-source aquifer.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3.2.2.1  Historical Groundwater Use In support of the CRBRP licensing activities at the CRN Site, TVA conducted a survey (completed in June 1973) to locate wells and springs within a two-mile radius of the site (Reference 2.3.2-8). The TVA survey reported that 110 wells and springs were located within two miles of the CRN Site. All of the wells were located across the Clinch River from the site, and nearly all of the wells inspected were small domestic wells of limited capacity (Reference 2.3.2-8). Reported well flow rates were generally less than 10 gpm, and reported well depths ranged from approximately 20 to 700 feet (ft) below ground. The study concluded that due to the abundance of surface water supplies and the relatively low yield of bedrock aquifers in the area, future groundwater use is unlikely to be significantly different than the present groundwater use.
Publicly available data regarding current and projected future residential well/spring use were not found at this time.
Water use in the Tennessee River Valley, which includes the Clinch River watershed, has been estimated for the years 2000, 2005, and 2010 (Reference 2.3.2-9; Reference 2.3.2-10; Reference 2.3.2-11). These reports tabulate water use on a variety of scales and serve as the primary basis for the estimation of present water use in the area of the CRN Site.
To characterize groundwater use in the area surrounding the site, data from these reports were totaled for Anderson, Knox, Loudon, Morgan, and Roane Counties (henceforth referred to as the groundwater study area). The CRN Site is located in northeast Roane County, while nearby population centers, including the cities of Oak Ridge and Knoxville, lie in the surrounding counties. Figure 2.3.2-2 shows the location of the site and the five counties that comprise the groundwater study area for water use characterization.
Surface water is the predominant source of water for all uses in the Tennessee Valley, accounting for 98.3 percent of total withdrawals in 2010 (Reference 2.3.2-11). Groundwater provided the remaining 1.7 percent, or about 205 mgd of withdrawals in the Tennessee Valley.
In the groundwater study area, surface water accounted for 99.7 percent of total withdrawals in 2010.
In the Tennessee Valley, thermoelectric power generation uses water exclusively from surface water withdrawals and is the dominant use category in the Tennessee Valley, as well as in the groundwater study area. Water withdrawals in 2010 for use categories (i.e., industrial, public supply and irrigation) other than thermoelectric power generation, were 97 percent from surface water and 3 percent from groundwater in the study area (Reference 2.3.2-11).
In the groundwater study area, total groundwater withdrawals for 2010 were 3.5 mgd, up from 3.3 mgd in 2005 (Reference 2.3.2-11; Reference 2.3.2-10). This also reflects a decrease in groundwater withdrawals relative to the estimates of withdrawals for 1985, which indicated withdrawals of at least 5 mgd (Reference 2.3.2-7). Table 2.3.2-4 presents groundwater withdrawals for the five counties in the groundwater study area for 2000, 2005, and 2010 by category (industrial, public supply, and irrigation); total withdrawals by category are shown in 2.3.2-4                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Figure 2.3.2-3. The largest category of use for groundwater withdrawals for the groundwater study area in 2010 was public water supply (66 percent), followed by industrial use (33 percent) and irrigation (less than 1 percent) (Reference 2.3.2-11).
As shown in Figure 2.3.2-3, there has been an increase in industrial use of groundwater and a decrease in groundwater use for public supply since 2000. These changes have primarily occurred in Knox County, which increased industrial use from 0.13 mgd to 1.13 mgd from 2000 to 2010 while reducing the use of groundwater as a source of public supply (Table 2.3.2-4).
Only Roane County has seen an increase in reported groundwater withdrawals since 2000, almost exclusively for public supply. No groundwater withdrawals were reported for Morgan County.
2.3.2.2.2    Current Groundwater Use The EPAs Safe Drinking Water Information System (SDWIS) database was queried for the five counties in the groundwater study area to identify public drinking water systems that utilize groundwater for supply. The database query was performed in July of 2013 and classifies water systems into three categories:
* Community water systems, which serve the same people year round (e.g., homes)
* Non-transient non-community water systems, which serve the same people but not year round (e.g., schools that have their own water supply)
* Transient non-community water systems, which do not consistently serve the same people (e.g., rest stops, campgrounds) (Reference 2.3.2-12)
The SDWIS query includes the water system name, county, population served, and system category and the results are summarized in Table 2.3.2-5.
Three community water systems in the groundwater study area were identified that use groundwater as the primary source of supply (Table 2.3.2-5). The town of Norris, Tennessee, located about 40 mi northeast of the CRN Site in Anderson County, serves the largest population of the three systems, while Johnson University, located east of Knoxville and Creekside Mobile Homes in Loudon County serve the next two larger populations. Two water systems were classified as non-transient non-community water systems that rely on groundwater, both of which appear to be industrial users in Knox County. Four transient non-community systems were identified, consisting of two campgrounds, a marina, and a yacht club.
TVA has identified additional groundwater users that were not included in the results obtained from queries in SDWIS. These are also provided in Table 2.3.2-5.
TDEC produced a source water assessment report in 2003, which was submitted to the EPA in compliance with the 1996 Safe Drinking Water Acts Amendments. Appendix A of the 2.3.2-5                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report assessment report lists water systems and sources by county. (Reference 2.3.2-13) This list indicates whether a water system uses multiple sources of water as opposed to the SDWIS database, which only reports the primary water source. However, TDEC does not indicate in what proportion the water sources are used (Reference 2.3.2-13). The community water systems that use groundwater (as of 2003) via wells or springs for at least part of their water supply are listed in Table 2.3.2-6. Groundwater intakes near the CRN Site are shown in Figure 2.3.2-4.
A later report by TDEC published in 2009 assesses Tennessee drinking water sources and potential threats to drinking water quality and quantity (Reference 2.3.2-14). The report states that a recent drought impacted 30 groundwater systems throughout the state, including the Oliver Springs Water Board in Roane County. The town of Oliver Springs is located approximately 2 mi northwest of Oak Ridge, Tennessee, and utilizes Bacon Spring for a portion of its water supply (Reference 2.3.2-14).
The report also notes the complicated geology of Middle and East Tennessee (karst, faulting, etc.) and urges additional assessment of groundwater resources in the state.
Information pertaining to individual wells in the vicinity of the CRN Site was obtained from the Tennessee Department of Environment and Conservation (TDEC), Division of Water Resources, Drinking Water Unit. This information was derived from water well driller reports submitted to TDEC following completion of water well drilling. Such reports include well location by either latitude and longitude or street address, date completed, static level, total depth, estimated yield, proposed use of well, casing depth, and finish type (i.e., open hole or screened). Figure 2.3.2-5 shows the location of individual wells within a 1.5-mile radius of the CRN Site, all of which are located in Roane County. Table 2.3.2-7 lists for each well the proposed use, estimated yield, total depth, casing depth, expected geologic unit in which the wells are located, and finish type. There are 32 residential wells, three commercial wells, and one farm well for a total of 36 individual wells. Estimated well yields range from 0.5 to 75 gallons per minute (three wells had no estimated well yield). Total depths range from 42 to 900 feet below grade, while casing depths range from 20 to 190 feet below grade. Twenty-eight of the wells are finished as open hole wells, while no finish type information was available for the remaining wells. The geologic unit in which wells are completed was inferred from regional geologic mapping, as this information was not available from TDEC. The actual geologic unit(s) from which a well obtains water may differ from what is shown in Table 2.3.2-7, depending on the exact well location and the well and casing depths.
2.3.2.2.3  Projected Groundwater Use Bohac and Bowen provide general future water use projections through 2035 for the Tennessee Valley. Predictions include a decrease of 21 percent in total withdrawals (surface water and groundwater), mostly due to the retirement of aging power plants. Industrial and public supply water uses are expected to increase by 31 percent and 30 percent, respectively. Groundwater uses may not increase in kind since the vast majority of users in the Tennessee Valley rely on surface water as a primary source. No groundwater-specific projections for water use are available in Bohac and Bowen. (Reference 2.3.2-11) 2.3.2-6                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report The current surrogate CRN SMR plant design does not require groundwater as a source for cooling water, potable water, or other plant needs. Makeup water for the closed-cycle cooling system is sourced from the Clinch River arm of Watts Bar Reservoir, while potable and other water comes from the Oak Ridge Department of Public Works. In addition, surface disturbance at the site is not expected to affect the recharge zones for those users shown on Table 2.3.2-6 or for intakes shown on Figure 2.3.2-4.
2.3.2.2.4    CRN Groundwater Use Summary Groundwater is not a primary source of water in the region as surface water is abundant and provides nearly all of the supply for users in the area. This abundant surface water coupled with relatively low productivity groundwater wells within a two-mile radius of the CRN Site, make it unlikely that significant differences from current usage will occur in the future.
Total groundwater withdrawals in the five counties surrounding the CRN Site have been fairly constant from 2000 to 2010, though the uses have changed and evolved in each county. The leading use of groundwater in the study area is for public supply, followed by industrial use.
From 2000 to 2010, industrial use has increased while public supply withdrawals have decreased in the five counties surrounding the CRN Site.
Present and known future offsite groundwater users are sufficiently distant from the CRN Site such that withdrawals would not affect or be adversely affected by the plant.
The surrogate CRN plant design does not rely on groundwater for any part of its operating supply. Thus, there is no groundwater demand due to the surrogate CRN SMR plant. There are no current or projected groundwater users for the CRN Site.
Temporary dewatering is required to maintain a dry excavation for the construction of the foundations for the CRN plant structures. Dewatering is to be accomplished using similar techniques as were used during the CRBRP excavations. These techniques included installation of horizontal gravity drains in the excavated rock faces and pumping from sumps located around the perimeter of the excavation and at the base of the excavation. Grouting of localized areas was performed when higher water inflow was encountered (Reference 2.3.2-8).
These dewatering methods are localized to the power block area excavation and to the areas immediately in the vicinity of the power block excavations.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3.3    Water Quality 2.3.3.1      Surface Water The proposed small modular reactors (SMRs) withdraw cooling water from the Clinch River arm of the Watts Bar Reservoir through an intake structure located near Clinch River Mile (CRM) 17.9. Heated water from the plant is to be returned to the Clinch River arm of the Watts Bar Reservoir by a discharge structure located near CRM 15.5.
2.3.3.1.1  Upper Tennessee River Basin The water quality data in the Upper Tennessee River Basin from 1994 to 1998 was summarized by the U.S. Geological Survey (USGS) in 2000. The report evaluated concentrations and distribution of bacteria, nutrients, pesticides, and volatile organic compounds (VOCs) in surface water and sediment, the influence of industry and mining on water quality, and the effects of toxic spills and releases. The study was performed as part of the USGS National Water-Quality Assessment Program, which, as of 2000, had evaluated 36 study areas throughout the United States. The report compared water quality data from the Upper Tennessee River to data from the other study areas, as well as to national water quality benchmarks, such as those for drinking water quality and protection of aquatic organisms.
In general, the report concluded that surface water in the Upper Tennessee River Basin usually meets existing guidelines for drinking water, recreation, and the protection of aquatic life.
Specific findings included:
* Bacteria levels frequently exceeded state standards in agricultural and urban areas. In agricultural areas, this was attributed to runoff from pasture land. In urban areas, this was attributed to wastewater infrastructure.
* Nutrients, including nitrogen and phosphorus, were found at elevated levels in some streams.
* Herbicides were detected in 98 percent of the stream samples collected, and insecticides were detected in 12 percent of samples. Concentrations were within drinking water standards, but exceeded aquatic life guidelines for some chemicals.
* Contamination from past industrial and mining activities was still present in many areas.
Contamination had resulted in fish consumption advisories for polychlorinated biphenyls (PCBs), dioxin, and mercury. Semivolatile organic compounds (SVOCs) were found in sediment at concentrations that exceeded aquatic life guidelines, and were attributed to coal mining.
* Spills and releases had resulted in fish and mussel kills in many parts of the basin (Reference 2.3.3-1) 2.3.3-1                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Specific findings were discussed for the Lower Clinch River Watershed, Watts Bar Reservoir, and Melton Hill Reservoir. Mercury was found to be a major contaminant in the drainages downstream from the Oak Ridge Reservation (ORR), including Whiteoak Creek watershed, and the lower Clinch River - Watts Bar Reservoir. Mercury, polychlorinated compounds (PCBs), and cesium-137 are known to have migrated to areas downstream of ORR. The State of Tennessee has posted a fish-consumption advisory for ORR drainages as well as Watts Bar Reservoir as a result of bioaccumulation of mercury and PCBs in some fish species. A fish-consumption advisory was also in place for Melton Hill reservoir due to the presence of PCBs and chlordane.
(Reference 2.3.3-1) 2.3.3.1.2  State Monitoring and 303(d) List The TDEC conducts monitoring of more than 7000 stations throughout the state, with 600 stations scheduled for sampling in fiscal year 2014-2015 (Reference 2.3.3-2). Water quality monitoring includes biological, chemical, and bacteriological analyses in wetlands, rivers, streams, reservoirs, and lakes.
There are 12 monitoring stations located on the Clinch River arm of the Watts Bar Reservoir, including four monitoring stations between Melton Hill Dam and the Clinch River Nuclear (CRN)
Site, and eight stations between the CRN Site and the confluence of the Clinch River arm with the Tennessee River arm of the reservoir. The closest station is located directly adjacent to the CRN Site, on the eastern side of the peninsula near CRM 18. Another station is located directly adjacent to the Barge/Traffic Area. (Reference 2.3.3-3)
Section 303(d) of the federal Clean Water Act requires that states develop a list of surface water bodies that are water quality limited or are expected to exceed water quality standards in the next two years. Streams that are water quality limited have one or more characteristics that violate water quality standards. These streams are considered to be impaired by pollution, and cannot fully meet their designated uses. (Reference 2.3.3-4)
In 2014, TDEC issued its 303(d) list for the year 2012. Table 2.3.3-1 lists the water bodies near the CRN Site which are listed as impaired.
2.3.3.1.3  River and Reservoir Compliance Monitoring Program TVA initiated a reservoir monitoring program, formerly called the Vital Signs Monitoring Program, in 1990 to provide information on the ecological health or integrity of major reservoirs in the Valley. Through the current Reservoir Ecological Health Program, TVA monitors ecological conditions at 69 sites on 31 reservoirs. Each site is sampled every other year unless a substantial change in the ecological health score occurs during a 2-year (yr) cycle. If that occurs, the site is sampled the next year to confirm that the change was not temporary. Roughly half the sites are sampled each year on an alternating basis. The program includes five ecological indicators (chlorophyll-a, dissolved oxygen (DO), sediment quality, benthic macroinvertebrates, and fish assemblage), which are monitored at up to four locations in each 2.3.3-2                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report reservoir. To complete the ecological health scoring process, the 20 to 100 percent scoring range is divided into categories representing good, fair, and poor ecological health conditions relative to what is expected given the hydrogeomorphology of the reservoir. (Reference 2.3.3-5) 2.3.3.1.3.1 Melton Hill Reservoir TVA monitors three locations on Melton Hill Reservoir: the deep, still water near the dam, called the forebay; the middle part of the reservoir; and the riverine area at the upper end of the reservoir, called the inflow. Monitoring is usually done on a two year cycle. The overall ecological condition of Melton Hill rated fair in 2012. Melton Hill received a good rating in 2006 and 2010 but rated fair in all other years monitored. The higher ecological health scores were primarily due to two indicators (chlorophyll and bottom life) rating near the upper end of their historic ranges. (Reference 2.3.3-6)
The following paragraphs summarize the result for the Melton Hill Reservoir Monitoring Program for 2012.
Dissolved Oxygen In 2012, DO rated poor at the forebay and good at the mid-reservoir location. A large portion of the lower water column at the forebay had low DO concentrations in June, resulting in a poor rating. DO has rated good at the mid-reservoir location all years monitored and typically has rated good in the forebay unless there was an extended period with low flow. Low flow conditions can allow water to sit long enough that oxygen in the lower water column becomes depleted as it is used in the natural process of decomposition. This was the case in 2012 and in 2000, 2001, and 2008 when DO rated fair at the forebay location. (Reference 2.3.3-6)
Chlorophyll In 2012, chlorophyll rated fair at the forebay and good at the mid-reservoir monitoring location.
Annual average chlorophyll concentrations have fluctuated through time at the mid-reservoir, with no specific trend of increasing or decreasing. Chlorophyll concentrations have shown an overall trend of increasing at the forebay since monitoring began in 1991. Chlorophyll rated good at the forebay during the 1991 to 1996 time period. Since 1998, chlorophyll ratings have fluctuated between fair and poor at this location. Reservoir flows have played a part in the year-to-year fluctuations as low-flow conditions tend to allow more time for algal populations to become established. (Reference 2.3.3-6)
Fish In 2012, the fish community rated good at the forebay, fair at the mid-reservoir, and poor at the inflow. Consistent with previous years, the fish assemblage at each monitoring location was characterized by lower numbers of fish and higher proportions of tolerant individuals than expected. As in most years, improved diversity at the mid-reservoir and forebay, respectively, resulted in higher ratings at these locations. (Reference 2.3.3-6) 2.3.3-3                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Bottom life In 2012, bottom life rated fair at the forebay and mid-reservoir locations and poor at the inflow.
Over the period of the monitoring program from 1994 to 2012, scores for bottom life have fluctuated within the low fair to poor range at the forebay and within the poor range at the inflow location. Scores have improved, however, at the mid-reservoir location since 1994 with scores shifting from the low end of the fair range to the middle of the fair range and even rating good in 2006. The improved ratings were primarily due to an increase in the number of organisms less tolerant of poor conditions. (Reference 2.3.3-6)
Sediment In 2012, sediment quality rated fair at the forebay because samples contained slightly more arsenic than would be expected to occur naturally. The mid-reservoir location rated good because no PCBs or pesticides were detected, and no metals had elevated concentrations.
Arsenic, chlordane, copper, and PCBs have exceeded suggested limits in some previous years.
(Reference 2.3.3-6) 2.3.3.1.3.2 Fort Loudoun Reservoir TVA monitors three locations on Fort Loudoun Reservoir: the forebay; the middle part of the reservoir; and the inflow. Fort Loudoun Reservoir was monitored annually from 1994 through 2007. In 2008, TVA began monitoring Fort Loudoun every other year. The ecological health condition of Fort Loudoun Reservoir rated fair in 2011. Conditions were similar to most previous years. Low ratings for three indicators (chlorophyll, bottom life, and sediment quality) typically reduce the reservoirs overall health score. In addition, DO has rated poor in some years.
(Reference 2.3.3-7)
The following paragraphs summarize the result for the Fort Loudoun Reservoir Monitoring Program for 2011.
Dissolved Oxygen In 2011, DO rated fair at the forebay and good at the mid-reservoir monitoring location. This indicator usually rates good at the mid-reservoir location, but ratings have varied between good, fair, and poor at the forebay, generally in response to reservoir flow conditions. TVA has installed aeration equipment to add oxygen to the deep water above Fort Loudoun Dam and to improve conditions immediately downstream. (Reference 2.3.3-7)
Chlorophyll In 2011, average summer chlorophyll concentrations were high at both monitoring locations, resulting in poor ratings. High chlorophyll concentrations are a consistent issue on Fort Loudoun, rating poor at both sites in most previous years. (Reference 2.3.3-7) 2.3.3-4                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Fish In 2011, the fish assemblage rated high fair at all three monitoring locations. The variety of fish collected at each location was good, but catch rates were slightly lower than desired and composition was dominated by a few species such as gizzard shad, bluegill, and/or largemouth bass. The fish community typically scores good or at the upper end of the fair range at the forebay and mid-reservoir, while scores at the inflow have generally fluctuated within the fair range. (Reference 2.3.3-7)
Bottom life In 2011, similar to previous years, bottom life rated poor at the forebay and inflow monitoring locations and fair at the mid-reservoir location. Relatively few organisms are usually collected from the forebay and inflow locations, and those collected are primarily species capable of tolerating poor conditions. Bottom life at the mid-reservoir location typically rates fair due to greater diversity, which includes a better representation of intolerant species such as mayflies.
(Reference 2.3.3-7)
Sediment In 2011, sediment quality rated fair at both the forebay and mid-reservoir monitoring locations because PCBs were detected. Sediment quality typically rates fair at both locations due to chlordane, PCBs, and/or zinc exceeding suggested limits. (Reference 2.3.3-7) 2.3.3.1.3.3 Watts Bar Reservoir TVA monitors four locations on Watts Bar Reservoir: the forebay; the middle part of the reservoir; and the Tennessee and Clinch River inflow locations. Samples are usually collected on a two-year cycle. The overall ecological health condition for Watts Bar Reservoir rated fair in 2012. Ecological health scores for Watts Bar have fluctuated between a high fair and poor and have generally followed reservoir flow conditions. Flow conditions in 2012 were low during most of the summer months in response to the generally dry weather pattern. The indicator most responsive to flow is DO, which rated poor at the forebay in 2012. In addition, common problems are elevated chlorophyll concentrations, poor bottom life, and the presence of metals and/or organic contaminants in the sediments. (Reference 2.3.3-5)
The following paragraphs summarize the result for the Watts Bar Reservoir Monitoring Program for 2012.
Dissolved Oxygen DO rated poor at the forebay and good at the mid-reservoir location. DO has rated good at the mid-reservoir location all years monitored except 2008 and 2010, when it rated fair and poor, respectively. Low DO levels (<2 milligrams per liter [mg/L]) have occurred in the lower water column at the mid-reservoir in several years, including 2012. However, the area affected was 2.3.3-5                                      Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report larger in 2010 than in other years, resulting in the only poor rating for this indicator at this location. Ratings have varied between good, fair, and poor at the forebay, primarily due to differences in reservoir flows. Poorer DO conditions typically occur as a result of reduced flows through the reservoir during dry conditions. TVA has installed aeration equipment to add oxygen to the deep water above Watts Bar Dam and to improve conditions immediately downstream.
(Reference 2.3.3-5)
Chlorophyll Chlorophyll rated poor at both locations monitored because of elevated concentrations. Annual average chlorophyll concentrations have fluctuated through time at the forebay, with no specific trend of increasing or decreasing. Chlorophyll concentrations have shown an overall trend of increasing at the mid-reservoir location since monitoring began in 1990. (Reference 2.3.3-5)
Fish The fish assemblage rated good at the Tennessee inflow location and at the upper end of the fair range at other monitoring locations. At all locations, the percent composition of tolerant individuals was higher than expected and catch rates were lower than expected. Better fish diversity at the Tennessee inflow location contributed to the higher (good) rating. (Reference 2.3.3-5)
Bottom life Bottom life rated good at the mid-reservoir, fair at the forebay and Clinch inflow locations, and poor at the Tennessee inflow location. Scores for bottom life in 2012 were similar to those of previous years at each monitoring location except the Clinch inflow location. Bottom life rated poor at the Clinch inflow location until 2004 when it received its first fair rating. Since 2004, bottom life at Clinch inflow location has scored within the fair to low-good range. Improvements in ratings at the Clinch inflow location are attributable to increases in the density and diversity of organisms in the samples collected from the reservoir bottom. (Reference 2.3.3-5)
Sediment Sediment quality rated fair at the forebay and mid-reservoir locations because concentrations of arsenic exceeded suggested background levels. Sediment quality commonly rates fair at both locations due to one or more contaminants: PCBs, chlordane, and/or arsenic. Additionally, the concentration of copper was elevated in the sample collected at the mid-reservoir location in 2009, and lindane was detected in the sample collected at the forebay in 2006. (Reference 2.3.3-5) 2.3.3.1.4  Preapplication Monitoring Program To support the evaluation of the suitability of the CRN Site and Barge/Traffic Area, TVA monitored the surface water on and in the immediate vicinity. This program consisted of 2.3.3-6                                      Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report characterization of surface water in the Clinch River arm of the Watts Bar Reservoir, as well as characterization of stormwater runoff on both the CRN Site and Barge/Traffic Area. The resulting data provides information to determine existing conditions for surface water. The parameters measured or analyzed include temperature, total metals, nutrients, acids/base/neutral compounds, PCBs, gross alpha, gross beta, radium 228, radium 226, oil and grease (O&G), pH, cyanide, phenols, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), color, bromide, surfactants, total organic carbon (TOC), sulfide, sulfate, ammonia-N, fluoride, TOC, and hardness. Pesticide monitoring was included in the July 2013 sampling. (Reference 2.3.3-8) The locations of the samples are provided in Figure 2.3.3-1, and the results are provided in Tables 2.3.3-2 and 2.3.3-3. Tables 2.3.3-2 and 2.3.3-3 provide the maximum concentrations for quarterly stormwater and surface water samples, respectively, collected in July 2013; March, May, and November 2014; and February, April, and June, 2015. All sample results for the Clinch River arm of the Watts Bar Reservoir upstream and downstream of the CRN Site indicate that TDECs most stringent numeric criteria are being met and that site runoff (should it occur) would not have a significant impact to water quality (Reference 2.3.3-8).
2.3.3.1.5    Biological Monitoring Program As part of the biological monitoring to characterize the aquatic community near the CRN Site, TVA collected and analyzed surface water and sediment samples at selected locations on the Clinch River arm of the Watts Bar Reservoir between CRM 15.5 and 22.0. The locations of the samples are shown in Figure 2.3.3-1.
The biological monitoring program data were collected to characterize baseline conditions of the aquatic habitats and communities in the reservoir immediately upstream and downstream of the CRN Site. This program focused on ecological health, but included collection of surface water quality and sediment chemistry data, as indicators of ecological health. Surface water samples were collected at four mid-channel locations, including three upstream locations at CRM 18.5, 19.7, and 22.0, and one downstream location at CRM 15.5. The surface water samples were collected monthly from March to December 2011. The samples from each month (a total of 10 months) were analyzed for nutrients (Kjeldahl nitrogen, nitrate plus nitrite-nitrogen, ammonia-nitrogen, total phosphorus, and orthophosphate), TOC, alkalinity, hardness, water clarity (turbidity and TSS), and total dissolved solids (TDS). The samples from every second month (April, June, August, October, and December) were analyzed for total and dissolved metals. In June, 2011, sediment samples were collected at three of the locations, including CRM 15.5, 18.5, and 22.0. Sediment samples were also collected from one location in Melton Hill Reservoir in June, 2011, and from two locations in the Tennessee River arm of Watts Bar Reservoir in June, 2010, and June, 2011. The sediment samples were analyzed for metals and organochloride pesticides and PCBs. (Reference 2.3.3-9)
The results from the biological monitoring program samples collected between March 2011 and December 2011 are provided in Tables 2.3.3-4 through 2.3.3-8, and are discussed in the following paragraphs (Reference 2.3.3-8).
2.3.3-7                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Nutrient concentrations typically were relatively high for nitrogen and moderate to low for phosphorus. Phosphorus concentrations were often low enough to be a limiting factor to phytoplankton, while nitrogen appeared to be underutilized. Chlorophyll a concentrations were low (<1.0-5.0 micrograms per liter [g/L]). Concentrations were below detectable levels (1 g/L) in approximately 53 percent of the samples, and only three of the 68 samples had concentrations greater than 2 g/L. Secchi-disk transparency ranged from 1.5 to 6.2 meters (m).
The average transparency was greater than 3 m (3.1m to 3.6 m) at each CRN Site sampling location (CRMs 15.5, 18.5, 19.7, and 22.0) in 2011, which is higher than typically observed in mainstream Tennessee River reservoirs. Turbidity ranged from 0.6 to 12 nephelometric turbidity units (NTU), with 68 percent of the values less than 4 NTUs. TSS ranged from 1 to 11 mg/L, with 85 percent of the values less than 4 mg/L. Phytoplankton populations were characterized by low abundance and appeared to be mainly the result of phytoplankton populations generated within Melton Hill Reservoir and transported downstream. Based on chlorophyll results, phytoplankton productivity in the sampled reach was very limited and phytoplankton populations were essentially in a senescent phase. Productivity was likely light-limited due to turbulence within the water column. Zooplankton assemblages were characterized by low abundance and diversity throughout the 10-month sampling period. As with phytoplankton, high turbulence and advection within the sampled reach likely limited zooplankton populations and affected their distribution. (Reference 2.3.3-8)
The typical pH was 7.5-7.9. All pH values were within the bounds of the State of Tennessee aquatic life criteria (6.5 to 9.0). The maximum water temperature was 79.6&deg;F, well below the State of Tennessee criteria (86.9&deg;F). Concentrations of metals in water were found to be below concentrations established by the State of Tennessee for protection of aquatic life. Ammonia concentrations were below the quantification limit (0.10 mg/L) in approximately 45 percent of the samples, while some samples had higher ammonia concentrations (0.16-0.19 mg/L) than generally expected. Ammonia concentrations typically are low (<0.15 mg/L) in aerated surface waters of TVA reservoirs; values greater than 0.15 mg/L are infrequent. PCBs and pesticides were not detected in the sediment samples collected near the CRN Site and metals concentrations were below EPA Region 4 ecological screening values for sediments.
(Reference 2.3.3-8)
As discussed in Subsection 2.3.1.1.2.7, daily thermal gradients were documented to occur in the reservoir during summer due to surficial warming during the hottest time of the day.
However, the warmer surface water was then either flushed out by daily dam releases from Melton Hill Dam, or its heat dissipated with nighttime atmospheric cooling. However, appreciable vertical gradients in DO concentrations existed at some locations during the July survey. Likewise, the slight deviation (4.87 mg/l) below the state water quality criterion for DO at CRM 15.5 in June 2011 may have resulted from periodic increases in flow mixing oxygenated water in the upper strata with oxygen-deficient water in the lower strata. (Reference 2.3.3-8)
Hourly hydro water releases from Melton Hill Dam typically range from no discharge to the maximum turbine capacity of approximately 20,000 cfs. However, intervals of 12 to 22 hr with no releases are common. Average hourly releases from Melton Hill Dam for April through 2.3.3-8                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report September of 2011 and 2013 were above average, but there were no hourly releases from Melton Hill Dam for about 42 percent of the time. By comparison, the percentage of hours with no releases is often in the range 60 to 70 percent. Therefore, data collected in 2011 and 2013 are likely more representative of conditions that exist during normal to above average flow conditions. During low flow years, the potential exists for greater spatial difference in temperatures and for increases in the magnitude and duration of stratification and resultant oxygen deficiencies. (Reference 2.3.3-8) 2.3.3.2    Groundwater This subsection describes the quality characteristics of groundwater aquifers that could affect plant water use and effluent discharge or be impacted by construction and operation of the SMRs to be built at the CRN Site.
The CRN plant design does not require groundwater as a source for cooling water, potable water, or other plant needs. Circulating cooling water is sourced from the Clinch River arm of Watts Bar Reservoir, while potable and other water comes from the Oak Ridge Department of Public Works. Temporary dewatering is required to maintain a dry excavation for the construction of the required foundations for the CRN plant structures.
2.3.3.2.1  Hydrogeochemical Characteristics 2.3.3.2.1.1 Regional Hydrogeochemical Characteristics As discussed in Subsection 2.3.1.2.1.2, the principal aquifers in the Valley and Ridge Province consist of carbonate rocks that are generally in communication with surface water features such as rivers or lakes. Other types of rocks in the province can yield water to wells where they are fractured or contain solution openings or are directly hydraulically connected to sources of recharge. Groundwater can also be present in the alluvium along streams and the residuum of weathered material that overlies most of the rocks in the area.
The chemical quality of water in the freshwater parts of the Valley and Ridge aquifers is similar for shallow wells and springs. The water is hard, a calcium-magnesium-bicarbonate type, and typically has a dissolved-solids concentration of 170 parts per million (ppm) or less. The ranges of concentrations are thought to be indicators of the depth and rate at which groundwater flows through the carbonate-rock aquifers. In general, the smaller values for a constituent represent water that is moving rapidly along shallow, short flow paths from recharge areas to points of discharge. This water has been in the aquifers for a short time and has accordingly dissolved only small quantities of aquifer material. Conversely, the larger values represent water that is moving more slowly along deep, long flow paths. Such water has been in contact with aquifer minerals for a longer time and thus has had greater opportunity to dissolve the minerals. Also, water that moves into deeper parts of the aquifers can mix with saltwater (brine) that might be present at depth (Reference 2.3.3-10).
2.3.3-9                                    Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report The chemical characteristics of the groundwater in the ORR aquitards range from a mixed-cation-bicarbonate water type at shallow depths to a sodium-bicarbonate water type at deeper depths, to sodium-calcium-chloride water type as evidenced from very deep wells.
These chloride-rich waters appear to be a zone of dilution on top of deeper saline sodium-calcium-chloride brines, similar to those encountered within the Conasauga Group at depths greater than 1000 ft in Melton Valley (Reference 2.3.3-11). The Knox aquifer is characterized by a calcium-magnesium-bicarbonate water type. The hydrogeologic conditions at the CRN Site are similar to those observed at the ORR with the exception of land disturbance areas resulting from earlier site work performed for the CRBRP where excavations and fill material are present.
2.3.3.2.1.2 Local Hydrogeochemical Characteristics The hydrogeochemical characteristics of the groundwater are summarized on Figure 2.3.1-23.
The shallow groundwater is characterized by mixed cation-bicarbonate type water, intermediate depth sodium-bicarbonate water, and deep sodium-chloride type water (Reference 2.3.3-12).
The transition to sodium-chloride type water occurs below approximately 300 ft and thus is not intercepted by onsite monitoring wells. A study of groundwater circulation in the deep system was conducted on the ORR, which included one well adjacent to the site (GW-214) (Reference 2.3.3-13). This well appears to be at the top of the saline zone (sodium-chloride type water) at a depth of 393 ft with a total dissolved solids measurement of 1693 ppm. The results of this study indicated that some active exchange of water from the shallower groundwater is occurring. This exchange was characterized as highly variable as a result of the paucity of vertically interconnecting fractures. A more recent study performed as part of the Melton Valley exit pathway monitoring program indicated a similar depth to saline groundwater (385 ft for monitoring well OMW1c) (Reference 2.3.3-14).
2.3.3.2.1.3 Site Hydrogeochemical Characteristics Site-specific groundwater chemistry data were collected from selected onsite observation wells (Reference 2.3.3-15). Table 2.3.3-9 summarizes the field parameter measurements for the selected wells. Table 2.3.3-10 summarizes the analytical results. Regional groundwater chemistry information was obtained from the USGS National Water-Quality Assessment Program (NAWQA) website for groundwater analyses from Roane, Anderson, and Knox counties to compare with the site-specific data. The results of these analyses are presented on a Piper trilinear diagram shown on Figure 2.3.3-2 (Reference 2.3.3-16). The site groundwater ranges mostly from calcium-bicarbonate to magnesium-bicarbonate type. The water is generally near neutral pH with a total dissolved solids concentration of less than 500 ppm. Examination of the figure indicates that, in general, the site groundwater chemistry is similar to the regional information from NAWQA. A notable exception is OW-202L, which is based on water chemistry, appears to be associated with the intermediate depth groundwater zone as defined on the ORR with a sodium-bicarbonate water type, alkaline pH, and higher total dissolved solids concentration. OW-202L was purged dry during sampling and had the highest field turbidity and pH measurement of the wells sampled (Table 2.3.3-9).
2.3.3-10                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3.3.2.2  Groundwater Quality 2.3.3.2.2.1 Local Groundwater Quality The CRN Site is located adjacent to the ORR which includes three DOE facilities: the Oak Ridge National Laboratory (ORNL), the Y-12 National Security Complex (Y-12), and the East Tennessee Technology Park (ETTP). The ORNL is composed of subareas including Melton Valley, Bethel Valley, and White Oak Creek. The Y-12 facility includes Bear Creek Valley, Upper East Fork Poplar Creek, and Chestnut Ridge. These facilities were constructed as part of the Manhattan Project during World War II and were involved with nuclear weapons production and research. A variety of chemicals and radionuclides are present at the sites. The primary classes of contaminants present include VOCs and radionuclides (primarily uranium, tritium, and strontium-90). Figure 2.3.3-3 presents a map showing the major groundwater plumes associated with the facilities (Reference 2.3.3-17). Examination of the map with respect to the location of the CRN Site indicates that none of the major groundwater plumes are impacting the site area.
2.3.3.2.2.2 Site Groundwater Quality To support the evaluation of the suitability of the proposed SMR site, the CRN Site field investigation includes monitoring groundwater at the CRN Site. As discussed in Subsection 2.3.1.2.1.4.2 and shown in Figure 2.3.1-18, observation wells were installed across the CRN Site to characterize the groundwater. Analytical results of quarterly sampling provide information on baseline groundwater conditions for the site.
Legacy Contaminants Current groundwater conditions at the CRN Site are influenced through proximity to ORR. As mentioned in Subsection 2.3.3.2.2.1, legacy contaminants from historic ORR operations include VOCs and radionuclides associated with the facilities. Contaminant plumes on ORR include volatile organic compounds along with cesium-137, strontium-90, and tritium at ORNL.
Contaminant plumes at Y-12 include uranium, nitrate, and mercury. Plumes at ETTP also include chromium-6 and technetium-99. (Reference 2.3.3-18) In addition, the regularly maintained, fenced White Oak Dam complex continues to settle legacy ORNL contaminants into the sediment of its 25-ac lake and, potentially, groundwater in the region. Groundwater monitoring, assessment, and corrective action are ongoing at the ORR sites.
Legacy groundwater contaminant plumes also include the former American Nuclear Corporation, located 15 mi southwest of the CRN Site on Braden Branch Creek near CRM 50.5.
From 1962 until 1970, American Nuclear Corporation produced radioactive sources and detectors. In 1970, contamination entering the Clinch River was traced to the American Nuclear Corporation, the operational license was revoked, and the plant closed. The plant was cleaned and fenced to allow the radioactive materials to decay in place. Contaminants include cobalt-60 and cesium-137.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Monitoring Network Baseline Observation wells were sampled on a quarterly basis by TVA from December 2013 through November 2014 to help characterize seasonal variations throughout the annual cycle to baseline current groundwater conditions (Reference 2.3.3-18). Sampling events were performed in December 2013 to January 2014, in April 2014, in August 2014, and in November 2014 to characterize groundwater conditions in winter, spring, summer, and fall, respectively.
Groundwater samples were collected using a submersible bladder pump. Each well was evacuated until field parameters stabilized; field parameters included sample depth, temperature, pH, oxidation-reduction potential, specific conductance, dissolved oxygen, and turbidity. Once stabilized, analytical samples were collected. Sample analysis included volatile organic compounds, semivolatile organic compounds, pesticides, PCBs, total petroleum hydrocarbons, metals, cyanide, radionuclides, and polycyclic aromatic compounds. (Reference 2.3.3-18)
The baseline range of field parameters for groundwater is summarized in Table 2.3.3-11. A more detailed summary, detailing data by sample depth and season is shown in Table 2.3.3-12.
Unlike most of the other field parameters, the minimum and maximum groundwater sample temperatures overlap during the annual cycle as shown in Table 2.3.3-13. Minimum temperatures range from 8.36 to 20.74 degrees Celsius (&deg;C; 47.05 to 69.33 degrees Fahrenheit
[&deg;F]) and maximum temperatures range from 13.7 to 24.44&deg;C (56.66 to 75.99&deg;F). The effect of well depth on the seasonal variance in temperatures is not apparent due to the wide range in depths for each well designation (i.e., upper, lower, and deep). Wells designated as upper had depths ranging from 8.76 to 31.5 m, while lower wells ranged from 35.97 to 50.3 m and deep wells ranged from 57.3 to 80 m; thus making the depth ranges rather continuous and less discrete.
As presented in TVAs Groundwater Quality Monitoring Report, analytical results of the 2013/2014 baseline sampling summarized in Table 2.3.3-14, were examined for legacy contaminants and for detections exceeding drinking water maximum contaminant levels (MCLs).
A detailed summary of sampling results is presented in Appendix 2.3.3-2-A. Only two detected analytes exceeded their MCL. Five fluoride results exceeded the MCL of 4 &#xb5;g/L; ranging from 6.9 to 14.2 &#xb5;g/L with the smallest exceedance from the OW422D well and the other four from the OW415L well. Lead had three detections, 5.5, 10.6, and 120 &#xb5;g/L, with the maximum detection from the fall sampling of OW419U exceeding leads action level of 15 &#xb5;g/L.
(Reference 2.3.3-18)
A summary of legacy contaminant detections is presented in Table 2.3.3-15. Of the regional legacy contaminants, none of the wells had detections of mercury or uranium. Similarly, none of the wells had detections of trichloroethylene or 1,1-dichloroethane. Detected legacy volatile organic compounds were limited to a solitary detection of tetrachloroethylene, along with twenty-two low level chloroform detections. Additionally, some wells exhibited nitrate detections; all low level. Detected legacy metals include a solitary arsenic detection, along with two 2.3.3-12                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report detections of cadmium. Barium was detected at low levels in several wells and chromium had five detections. The legacy radionuclides tritium, strontium 90, and technetium 99 were detected a few times.
Table 2.3.3-16 presents a summary of detected analytes.
Well Cluster 422 During the CRN Site subsurface investigation, a three-well cluster was installed east of the OW-101 well cluster, at boring location MP-422 (OW-422 U, L, and D). Following drilling, wells were scheduled to be completed by casing, screening, filtering, sealing, and packing to produce a viable groundwater monitoring well. During well completion, groundwater contamination was observed in OW-422L. TDEC was notified and was provided with the results of well sampling.
The contamination was determined to be non-radiological, petroleum products (gasoline range organics). Due to the contamination in OW-422L, this well cluster (OW-422 U, L, and D) was not developed; however, the well cluster remains in place, locked and under TVA control. TVA has no plans to perform any additional work in the location, and TDEC will make a determination regarding the disposition of the well cluster. Because the wells were not developed and monitoring of water levels in these wells was not performed, the OW-422 well series is not included in the discussion of site observation wells. Well clusters OW-428 and OW-429 (installed north and south of the OW-422 cluster) were installed to provide replacement geological/groundwater data. (Reference 2.3.3-18)
Some permanent observation well clusters (OW-428 and OW429), located in the area around OW-422, were sampled after well development and no evidence of petroleum products (gasoline range organics) was observed in January 2014. The contamination seems to be restricted to the immediate area around well OW-422. No evidence of petroleum products (gasoline range organics) was observed before or after the 72-hour (hr) pumping test conducted near the OW-428 U,L, and D well cluster (up dip [higher in the geologic unit] of OW-422L).
Water quality sampling in discharge water from the 72-hr pumping test also showed no detection of volatile organic compounds. Finally, gross alpha and beta radionuclides were below minimum detectable concentration levels in the discharge water from the pumping test.
Therefore, the contamination seems to be a localized issue around well OW-422.

Laboratory Geochemical Results 1
Analytical error is the difference between the sum of the cations and the sum of the anions divided by the sum of the anions and cations and multiplied by 100% (the anion and cation concentrations are in milliequivalents per liter). The analytical error represents the charge balance error of the analysis.
2 Data Qualifier Definitions:
J = Estimated quantitation based on associated QC data JQ = Estimated quantitation; value is between the reporting limit and the detection limit JH = Estimated quantitation; possibly biased high based on QC data U = Undetected UL = Undetected; data biased low: the reporting detection limit is higher than indicated 3
Bicarbonate concentration determined by dividing the Bicarbonate Alkalinity by 0.8202 (Reference 2.3.3-20) 4 Bicarbonate concentration is suspect due to high sample pH (pH = 9.58)

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.4    ECOLOGY This section describes the terrestrial, wetland, and aquatic ecology of the Clinch River Nuclear (CRN) Site and resources in the vicinity of the CRN Site that could be affected by the construction and operation of two or more small modular reactors (SMRs). Details regarding the locations of proposed facilities on the CRN Site and in offsite areas, construction activities and the areas affected, and the planned operation of facility systems, are provided in Chapter 3.
Subsection 2.4.1 describes the potentially affected terrestrial resources, including wetlands, and Subsection 2.4.2 describes the potentially affected aquatic resources. Transmission lines from the facility are expected to be added within existing onsite and offsite transmission line rights-of-way (ROWs) and within a short segment of a new ROW within the CRN Site. ROWs for cooling water intake and discharge pipelines are located within the CRN Site.
2.4.1  Terrestrial Ecology The construction and operation of two or more SMRs at the CRN Site has the potential to affect terrestrial resources occurring on and within the vicinity of the approximately 935-acre (ac) CRN Site, including upland and wetland habitats and the ecological communities they support. In addition, upland and wetland communities could be affected by construction in two offsite areas:
the Barge/Traffic Area immediately northwest of the CRN Site entrance, and the approximately 5-mile (mi) segment of the existing 500-kilovolt (kV) transmission line ROW east of the CRN Site. Improvements to the barge facility, roads, and intersections are planned at the Barge/Traffic Area. Installation of a 69-kV underground transmission line is planned for the existing ROW east of the CRN Site. This subsection describes the ecological characteristics of the terrestrial resources potentially affected by the construction and operation of SMRs at the CRN Site, barge and roadway infrastructure improvements in the Barge/Traffic Area, installation of a 69-kV underground transmission line, and modifications to the existing transmission system.
2.4.1.1      Upland Habitats 2.4.1.1.1  CRN Site The CRN Site is located within the Ridge and Valley Ecoregion, a relatively low-lying area with roughly parallel ridges and valleys that extends across eastern Tennessee between the Blue Ridge Mountains to the east and the Cumberland Plateau to the west. The CRN Site overlaps two subdivisions of the Ridge and Valley Ecoregion: the Southern Limestone/Dolomite Valleys and Rolling Hills Ecoregion and the Southern Dissected Ridges and Knobs Ecoregion (Figure 2.4.1-1). Over 95 percent of the CRN Site is within the Southern Limestone/Dolomite Valleys and Rolling Hills, a diverse ecoregion with a geology characterized by limestone, cherty dolomite, and mostly undulating landforms of rounded ridges and valleys with many caves and springs. Vegetation land cover includes forests, pasture, and agricultural crops, and development in the ecoregion includes commercial, industrial, and residential land uses. Only the southern tip of the Clinch River Property peninsula is within the Southern Dissected Ridges 2.4.1-1                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report and Knobs Ecoregion. The vegetation community within these lower elevations of the Southern Dissected Ridges and Knobs Ecoregion is mainly mixed mesophytic forest dominated by white oak (Quercus alba) and tulip poplar (Liriodendron tulipifera). (Reference 2.4.1-1)
Field surveys of vegetation on the Clinch River Property, including the CRN Site as well as the adjacent Grassy Creek Habitat Protection Area (HPA), were conducted by Tennessee Valley Authority (TVA) in April and July of 2011 and September of 2013. The surveys were performed to characterize terrestrial vegetation communities, identify invasive plants, and search for listed plant species with the potential to occur in the habitats present (Reference 2.4.1-1). Based on interpretation of aerial photographs and the findings of these field surveys, dominant vegetation communities and other land cover types on the CRN Site were mapped (Figure 2.4.1-1). Over 75 percent of the CRN Site is covered by forest, approximately 22 percent is covered by herbaceous vegetation, and less than 1 percent (approximately 0.3 percent) is covered by small ponds. The remaining 2 percent of the CRN Site is classified as roads and developed areas.
Table 2.4.1-1 shows the percentage of the CRN Site covered by each type of vegetation community or land use and the estimated acreage of each type based on a total CRN Site area of approximately 935 ac. Figure 2.4.1-1 depicts land cover types on the CRN Site.
TVA identified the dominant vegetation communities on the CRN Site as mixed evergreen-deciduous forest, deciduous forest, evergreen forest, and herbaceous vegetation.
Characteristics of the vegetation communities on the CRN Site are described below, including examples of species generally representative of these community types. Lists of species actually recorded in vegetation surveys of the communities on the Clinch River Property are identified by their common and scientific names in Table 2.4.1-2. (Reference 2.4.1-1)
Mixed evergreen-deciduous forest consists of forest stands in which both evergreen and deciduous species contribute 25 to 75 percent of the total canopy cover. On the CRN Site, this forest occurs mostly as oak-hickory-pine dry forest on ridges. The dominant oaks include black oak (Quercus velutina), chestnut oak (Q. montana), northern red oak (Q. rubra), southern red oak (Q. falcata), and white oak. The dominant hickories include mockernut hickory (Carya tomentosa), pignut hickory (C. glabra), and shagbark hickory (C. ovata). The dominant pine is the Virginia pine (Pinus virginiana), and scattered eastern red cedars (Juniperus virginiana) are also present. Common understory species include black gum (Nyssa sylvatica), muscle wood (Carpinus caroliniana), and sourwood (Oxydendrum arboreum), and the herbaceous layer includes running ground cedar (Diphasiastrum digitatum), spotted wintergreen (Chimaphila maculata), ebony spleenwort (Asplenium platyneuron), black snakeroot (Cimicifuga racemosa),
Christmas fern (Polystichum acrostichoides), little brown jug (Hexastylis arifolia), southern wood sorrel (Oxalis corniculata), and yellow giant hyssop (Agastache nepetoides). (Reference 2.4.1-1)
Deciduous forest, the second most prevalent forest type on the CRN Site, is characterized by trees with overlapping crowns and a canopy of more than 75 percent deciduous species. The deciduous forests on the CRN Site include three subtypes. The most extensive subtype is mixed mesophytic hardwood forest with a canopy that is dominated by tulip poplar and also 2.4.1-2                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report includes American beech (Fagus grandifolia), white oak, and yellow buckeye (Aesculus flava).
The understory is varied and includes American holly (Ilex opaca), Carolina buckthorn (Rhamnus caroliniana), flowering dogwood (Cornus florida), maple-leaf viburnum (Viburnum acerifolium), pawpaw (Asimina triloba), sassafras (Sassafras albidum), serviceberry (Amelanchier arborea), and wild black cherry (Prunus serotina). The diverse herbaceous layer includes bishops cap (Mitella diphylla), blue cohosh (Caulophyllum thalictroides), blood root (Sanguinaria canadensis), dog-tooth violet (Erythronium americanum), foam-flower (Tiarella cordifolia), Jack-in-the-pulpit (Arisaema triphyllum), maidenhair fern (Adiantum pedatum),
Solomons seal (Polygonatum biflorum), and many others. (Reference 2.4.1-1)
A second deciduous forest subtype, calcareous forest, occurs in several areas within the CRN Site that are underlain by limestone. The majority of the forested areas underlain by limestone are within the Grassy Creek HPA on the Clinch River Property immediately north of the CRN Site and on a few mesic slopes on the CRN Site adjacent to the Clinch River arm of the Watts Bar Reservoir. Species with affinities for calcareous soils occur in these areas, including eastern red cedar, eastern redbud (Cercis canadensis), bladdernut (Staphylea trifolia), and herbs such as Appalachian bugbane (Cimicifuga rubifolia), glade fern (Diplazium pycnocarpon), green violet (Hybanthus concolor), Jacobs ladder (Polemonium reptans), and walking fern (Asplenium rhizophyllum). Two Tennessee species of special concern that occur in this forest are the herbs American ginseng (Panax quinquefolius) and spreading false-foxglove (Aureolaria patula).
(Reference 2.4.1-1)
A third deciduous forest subtype, wetland forest, occurs near the edge of the Clinch River arm of the Watts Bar Reservoir and in association with the riparian areas of tributaries on the CRN Site. These forests are dominated by American sycamore (Platanus occidentalis), black willow, buttonbush (Cephalanthus occidentalis), silky dogwood (Cornus amomum), and tag alder (Alnus serrulata). Other common trees and shrubs observed include persimmon (Diospyros virginiana),
box elder (Acer negundo), Chinese privet (Ligustrum sinense), tall false indigo (Amorpha fruticosa), multiflora rose (Rosa multiflora), and silver maple (Acer saccharinum). Herbaceous species in these wetland forests include netted chain fern (Woodwardia areolata), jewelweed (Impatiens capensis), lizard tail (Saururus cernuus), rose mallow (Hibiscus sp.), waterwillow (Justicia americana), yellow flag (Iris pseudacorus), and several species of grasses, rushes, and sedges. (Reference 2.4.1-1) Each of the wetlands on the CRN Site is described in Subsection 2.4.1.2 and mapped in Figure 2.4.1-1.
Evergreen forest present on the CRN Site consists of remnant areas of loblolly pine (Pinus taeda) and white pine (Pinus strobus) plantations, which cover a total of approximately 3 percent of the CRN Site (Reference 2.4.1-1).
An herbaceous vegetation community consists of greater than 25 percent grasses and forbs.
Herbaceous vegetation is the dominant cover on approximately 22 percent of the CRN Site, largely as a result of historical construction activities during which approximately 240 ac of the CRN Site were cleared (Reference 2.4.1-2). Much of this area was eventually refilled and revegetated with non-native species, such as tall fescue (Festuca arundinacea) and sericea 2.4.1-3                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report lespedeza (Lespedeza cuneata). These areas are undergoing secondary succession, principally by weedy species that include black-eyed Susan (Rudbeckia hirta), broom-sedge (Andropogon virginicus), Canada goldenrod (Solidago canadensis), Johnson grass (Sorghum halepense),
Queen Annes lace (Daucus carota), tickseed (Coreopsis grandiflora), and other common forbs.
Eastern red cedar is scattered throughout these areas, resulting in the appearance of a cedar barren or glade. (Reference 2.4.1-1)
One area of herbaceous vegetation differs from that found on the rest of CRN Site in having a predominantly native flora. This small area covers about 1.4 ac in a transmission line ROW and resembles a disturbed cedar glade, which is an area of exposed limestone that supports sparse vegetation dominated by low-growing herbaceous species and eastern red cedar. In addition to red cedar and winged elm, herbs found in the marginal cedar glade area include butterfly weed (Asclepias tuberosa), hoary puccoon (Lithospermum canescens), false pennyroyal (Hedeoma pulegioides), pale spiked lobelia (Lobelia spicata), rose pink (Sabatia angularis), roundleaf thoroughwort (Eupatorium rotundifolium), twining snoutbean (Rhynchosia tomentosa), and whorled milkweed (Ascelpias verticilliata). Though the CRN Site contains several native species found in cedar glade habitat, its small size and high level of previous disturbance limits the importance of the CRN Site. (Reference 2.4.1-1) Given its position on the landscape, it is likely the plant community formed as a result of disturbance associated with previous work on the Clinch River Site and construction of the 161-kV Kingston FP - Fort Loudoun HP #1 line.
Considered along with the small size and anthropogenic origin of the plant community, the absence of any rare plant species typical of glades further indicates that this area possesses little if any conservation value.
Barge/Traffic Area In the Barge/Traffic Area, field surveys were conducted in May 2015 to characterize the terrestrial plant communities of the area east of TN 58. Surveys were conducted on the portions of the Barge/Traffic Area (101-ac) with the highest potential for disturbance that had not been previously surveyed. The survey included areas representative of each vegetation type present in the Barge/Traffic Area. Vegetation types found in this area were a combination of deciduous forest and herbaceous vegetation. These plant communities are common and well-represented throughout the region. None of the forest stands had characteristics indicative of old growth forest. (Reference 2.4.1-3)
Deciduous forest covers more than 90 percent of the Barge/Traffic Area. Common overstory species in dry upland forest include American beech, black gum, chestnut oak, mockernut hickory, red maple, scarlet oak (Quercus coccinea), sourwood, umbrella magnolia, and white oak. The understory consists of flowering dogwood, lowbush blueberry (Vaccinium angustifolium), and mountain laurel (Kalmia latifolia). Herbaceous plants are sparse and include Christmas fern, muscadine (Vitis rotundifolia), and wild yam (Dioscorea villosa). The deciduous forest in the Barge/Traffic Area also includes forested wetlands located in bottomlands associated with the Clinch River arm of the Watts Bar Reservoir. These deciduous forests 2.4.1-4                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report contain overstory species that include American sycamore, black willow, green ash, red maple, and sweetgum. (Reference 2.4.1-3)
Herbaceous vegetation occurs on less than 10 percent of the surveyed portion of the Barge/Traffic Area. Fields and maintained power line ROWs account for the vast majority of herbaceous vegetation in the area. Most of these herbaceous communities are dominated by plants indicative of early successional habitats, including many non-native species. Common species in these disturbed areas include Japanese honeysuckle, lobed tickseed (Coreopsis auriculata), sericea lespedeza, showy goldenrod (Solidago speciosa), Smalls ragwort (Packera anonyma), southern blackberry (Rubus sp.), and winged sumac (Rhus copallinum). Several small, emergent wetlands support a higher proportion of native species including buttonbush, common rush (Juncus effusus), groundnut (Apios americana), jewelweed, lizards tail, shallow sedge (Carex lurida), silky dogwood, squarrose sedge, and tall false indigo. (Reference 2.4.1-3) 2.4.1.2      Wetland Habitats Sections 401 and 404 of the Clean Water Act and Executive Order 11990, Wetlands Protection, provide regulatory protection for wetlands. Executive Order 11990 requires all federal agencies to minimize the destruction, loss, or degradation of wetlands when carrying out their responsibilities, and to preserve and enhance the natural and beneficial values of wetlands.
Before performing certain activities in wetlands, a Section 404 permit from the U.S. Army Corps of Engineers (USACE) may be required, depending on the size of the wetland and its hydrologic connectivity to a navigable waterway. Section 401 provides states with the ability to verify whether activities allowed under Section 404 are compliant with state water quality standards. In Tennessee, the Division of Water Pollution Control of the Tennessee Department of Environment and Conservation (TDEC) is in charge of issuing Section 401 water quality certifications through the Aquatic Resource Alteration Permit. (Reference 2.4.1-4) 2.4.1.2.1  CRN Site Wetlands Screening of wetland habitats on the CRN Site initially involved a review of National Wetland Inventory (NWI) maps and soil survey maps. Subsequently, field surveys were performed during January, April, and May of 2011, and the boundaries of the 12 wetlands on the CRN Site were delineated. Wetland identifications were performed in accordance with USACE methods, which require documentation of hydrophytic vegetation, hydric soils, and wetland hydrology. Broader definitions of wetlands, such as those provided by Executive Order 11990, the U.S. Fish and Wildlife Service (USFWS), and the TVA Environmental Review Procedures, also were considered in the wetland determinations for the CRN Site.
During a site visit on September 23, 2013, jurisdictional determinations were conducted by staff of the USACE to determine if each wetland meets the criteria for regulation under USACE jurisdiction. The TVA Rapid Assessment Method (RAM) was used to evaluate wetland conditions and identify wetlands with possible ecological significance. The TVA RAM uses six metrics that correspond to wetland indicator functions to differentiate wetlands on the basis of 2.4.1-5                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report their condition: wetland area/size; upland buffers and surrounding land use; hydrology; habitat alteration and development; special wetlands (biodiversity); and plant communities, interspersion, and microtopography. Wetlands may be classified into three categories of wetland quality using the TVA RAM. Assignment to categories is based on scoring of wetland characteristics based on the six metrics, with a higher total score generally indicating that a wetland warrants assignment to a higher category. Category 1 includes wetlands that are limited quality waters, which are wetlands that have been degraded, have limited potential for restoration, or are of such low functionality that lower standards for avoidance, minimization, and mitigation can be applied. Category 2 includes wetlands of moderate quality as well as wetlands that are degraded but have a reasonable potential for restoration. Category 3 typically includes wetlands of very high quality and wetlands of concern regionally and/or statewide, such as wetlands that provide habitat for threatened or endangered species. (Reference 2.4.1-4)
Characteristics of each of the onsite wetlands, including wetland classification, TVA RAM category and score, acreage, and jurisdictional status, are summarized in Table 2.4.1-3. The locations of the onsite wetlands are shown in Figure 2.4.1-2, and each wetland is described below.
Wetland 1 (W001) is a forested wetland associated with a floodplain/terrace of the Clinch River.
This wetland covers 0.67 ac of the CRN Site and exhibits wetland hydrology and connectivity.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.4.1.2.2  Barge/Traffic Area Wetlands Field surveys of wetlands in the Barge/Traffic Area were completed by TVA in April 2015.
Wetland determinations and assessments of wetland quality were performed as described above for the CRN Site. (Reference 2.4.1-5) Characteristics of each of the Barge/Traffic Area wetlands, including wetland classification, TVA RAM category and score, acreage, and jurisdictional status, are summarized in Table 2.4.1-3. The locations of the Barge/Traffic Area wetlands are shown in Figure 2.4.1-2, and each wetland is described below.
Wetland 13 (W013) is a scrub-shrub/emergent wetland associated with a channelized, perennial, unnamed tributary to the Clinch River arm of the Watts Bar Reservoir. The wetland is under a transmission line and is maintained as a scrub-shrub/emergent wetland as the result of vegetation maintenance in the ROW. This wetland covers 3.73 ac and exhibits wetland hydrology and connectivity. Field indicators of hydric soils are lacking, possibly due to extensive site disturbance during the 1970s during site preparation for the Clinch River Breeder Reactor project and subsequent sedimentation. Dominant hydrophytic vegetation in the ROW includes green ash, black willow, broom panicgrass (Dicanthelium scoparium), silky dogwood, common rush, swamp rose (Rosa palustris), southern blackberry (Rubus argutus), red maple, and swamp dock (Rumex verticillatus). Based on its TVA RAM score, this wetland is in Category 2, moderate quality). (Reference 2.4.1-5)
Wetland 14 (W014) lies southeast of Wetland 13, and the two wetlands are separated by the existing road bed from the barge facility. Wetland 14 is similar in type, landscape position, and vegetation to Wetland 13 and is associated with the same unnamed perennial stream. The wetland covers 3.05 ac. Based on its TVA RAM score, this wetland is in Category 2, moderate quality. (Reference 2.4.1-5)

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.4.1.3      Important Terrestrial Habitats U.S. Nuclear Regulatory Commission (NRC) guidance (NUREG 1555, Standard Review Plans for Environmental Reviews for Nuclear Power Plants: Environmental Standard Review Plan, and Regulatory Guide 4.2, Preparation of Environmental Reports for Nuclear Power Stations) identifies important habitats as the following:
* Wildlife sanctuaries, refuges, and preserves
* Habitats identified by the USFWS or state Natural Heritage Programs as unique, rare, or a priority for protection
* Critical habitats designated by the USFWS to protect listed species
* Wetlands, floodplains, or other resources protected by federal regulations or executive orders or by state regulations (Floodplains are discussed in Section 2.3, Water)
Important terrestrial habitats include natural areas as well as habitats such as these that have been identified by government agencies as unique, rare, or a priority for protection. Natural areas include managed areas and ecologically significant sites. Managed areas include lands held in public ownership that are managed by an agency to protect and maintain certain ecological and/or recreational features. Ecologically significant sites are either tracts of privately owned land that are recognized by resource biologists as having significant environmental resources or identified tracts on TVA lands that are ecologically significant but not specifically managed by the TVAs Natural Areas program. (Reference 2.4.1-6)
A 2011 report by the TVA assessed natural areas on, adjacent to, and within 3 mi of the CRN Site. A review of the TVA Natural Heritage Project Database indicates that a number of natural areas are located immediately adjacent to the CRN Site. (Reference 2.4.1-6) These areas are described below:
* The Grassy Creek HPA adjoins the northern boundary of the CRN Site and is located along and south of Grassy Creek (Figure 2.4.1-1). The Grassy Creek HPA includes 265 ac that provide a buffer for sensitive habitat surrounding and immediately south of Grassy Creek and the Grassy Creek embayment of the Clinch River arm of the Watts Bar Reservoir.
(Reference 2.4.1-6) A plant species designated as a state species of special concern, spreading false-foxglove (Aureolaria patula), is among the species with habitat protected by the Grassy Creek HPA and was found in the HPA during field surveys (Reference 2.4.1-1).
* The Oak Ridge Reservation (ORR) adjoins the land boundaries of the CRN Site to the east, north, and west. The DOE manages this 34,000-ac reservation, which is used variously for manufacturing, laboratory research, forest management, and ecosystem process research (Reference 2.4.1-6). An analysis by the Oak Ridge National Laboratory (ORNL) of natural areas, managed areas, and other designated areas within the ORR identified the following categories and numbers of terrestrial or wetland areas:
2.4.1-10                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 47 natural areas 18 reference areas 5 conservation management areas 8 habitat areas 8 potential habitat areas
  -  8 special management zones (Reference 2.4.1-7)
Figure 2.4.1-3 provides a map of these ORR designated areas within approximately 3 mi of the CRN Site. Five of these designated terrestrial or wetland areas on the ORR are immediately adjacent to the CRN Site or in close proximity:
The East Tennessee Technology Park Filtration Plant Wetland (Natural Area 33) is a 7-ac wetland adjacent to a water filtration lagoon located near the northwest corner of the CRN Site. This area provides habitat for shining ladies-tresses (Spiranthes lucida), a plant species state listed as threatened.
The Grassy Creek Power Line Area (Cooperative Management Area 1) is a 51-ac linear area extending northeast along Bear Creek Road adjacent to the northern corner of the Grassy Creek HPA.
The Grassy Creek Security Site (Reference Area 22) includes 43 ac adjoining the northern tip of the CRN Site and the Grassy Creek HPA. Reference areas contain special habitats or features and also may serve as control areas for research, monitoring, or related activities. This area includes limestone outcrops and some plants uncommon on the ORR.
The Raccoon Creek Barren (Reference Area 8) includes 62 ac located approximately 1500 feet (ft) east of the eastern corner of the CRN Site and extending upland from the shoreline of the Clinch River arm of the Watts Bar Reservoir. It contains a rare community, a cedar-post oak barren-glade on shallow limestone. It has been proposed by TDEC for protection under the Natural Areas Preservation Act.
The New Zion Boggy Area (Natural Area 42) includes 376 ac located less than 0.5 mi northeast of the CRN Site at its closest point. It contains oak-hickory uplands and a boggy forested wetland that is a rare natural community. It is called boggy because the area includes groundwater seeps and a sinking creek in a headwater area with a sphagnum moss/fern wetland and pools. This uncommon habitat and the presence of red chokeberry (Aronia arbutifolia) contribute to the conservation value of this area.
(Reference 2.4.1-7) This area is located within a small subwatershed of an unnamed tributary of the Clinch River arm of the Watts Bar Reservoir, immediately east of the CRN Site.
* The Oak Ridge State Wildlife Management Area (WMA) is located primarily on the ORR and adjacent to the CRN Site. The WMA is a 37,000-ac area managed by the Tennessee 2.4.1-11                              Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Wildlife Resources Agency (TWRA) for hunting of small and large game. (Reference 2.4.1-6)
* The Oak Ridge National Environmental Research Park (NERP) includes approximately 20,000 ac within the boundaries of the ORR and adjoining the CRN Site. The NERP is managed by the ORNL for the DOE. It provides protected land for use in education and research in environmental sciences and is used as an outdoor laboratory for studying present and future environmental consequences from energy-related issues. (Reference 2.4.1-6) The NERP was designated as an international biosphere reserve in 1989; it is one of six units of the Southern Appalachian Biosphere Reserve (Reference 2.4.1-8).
Also within the boundaries of the ORR, five proposed state natural areas (SNA) have been nominated for future designation and protection under the Natural Areas Preservation Act.
These five areas are considered ecological core areas and contain several smaller natural areas within their boundaries. One proposed SNA, New Zion, is immediately adjacent to the CRN Site. The other four proposed SNAs are within 3 mi of the CRN Site. (Reference 2.4.1-6)
These five proposed SNAs on the ORR are described below.
* The New Zion Unit proposed SNA comprises 2891 ac in the western portion of the ORR and immediately east of the CRN Site. It includes portions of the Haw Ridge uplands, including rock outcrops, and the Raccoon Creek Embayment of the Clinch River arm of the Watts Bar Reservoir as well as wetlands. Several rare and uncommon plant species occur in this area.
(Reference 2.4.1-6)
* The Copper Ridge Unit proposed SNA comprises 3908 ac in the southern portion of the ORR and is located 2.3 mi southeast of the CRN Site. Prominent features include Copper Ridge, extensive river bluffs along Melton Hill Reservoir, a variety of forest community types, several caves and sink holes, ravines, springs, seeps, and forested wetlands. (Reference 2.4.1-6)
* The Black Oak Ridge Unit proposed SNA comprises 2929 ac in the western part of the ORR northeast of the CRN Site. This natural area includes two sections, East Black Oak Ridge and West Black Oak Ridge, separated by the Poplar Creek water gap and Blair Road.
Prominent features are the East Fork Poplar Creek floodplain, Black Oak Ridge and McKinney Ridge, river bluffs, mixed hardwood-native pine forest, and a large forested wetland. (Reference 2.4.1-6)
* The Pine Ridge-Bear Creek Valley Unit proposed SNA comprises 4584 ac adjacent to the northern boundary of the DOE Reservation northeast of the CRN Site. Topographic features of the area include Pine Ridge and the western portion of East Fork Ridge. Also included are an extensive area of unfragmented forest and a variety of wetland habitat types, including headwater wetlands, seeps, marshes, and forested wetlands and sandstone outcrops. (Reference 2.4.1-6)
* The Walker Branch-Three Bend Unit proposed SNA comprises 6059 ac to the east of the CRN Site in the eastern portion of the ORR. It includes the entire Three Bend Scenic and 2.4.1-12                              Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Wildlife Area and one of the worlds largest populations of a rare wildflower species, tall larkspur. (Reference 2.4.1-6)
Outside the ORR, two officially designated SNAs are located within a 3-mi radius of the CRN Site (Reference 2.4.1-6):
* The Campbell Bend Barrens designated SNA is approximately 1.7 mi northwest of and across the Clinch River from the CRN Site. This 35-ac area managed by TDEC consists of small barrens that are a rare community type in a region where much of the land has been developed or converted to agriculture. The barrens community within the natural area covers approximately 4 to 6 ac. Eastern red cedar, white pine, post oak (Quercus stellata),
dwarf chinquapin oak (Q. prinoides), and other hardwoods are scattered throughout the open grassland community of Campbell Bend, and the dominant grasses include little bluestem (Andropogon scoparius), big bluestem (A. gerardii), and side-oats gramma (Bouteloua curtipendula). (Reference 2.4.1-6)
* The Crowder Cemetery Cedar Barrens designated SNA is approximately 1.8 mi west of and across the Clinch River from the CRN Site. This 15-ac area managed by TDEC has grasslands in a matrix of mixed oak-pine with eastern red cedar and hardwoods that are scattered throughout the barrens. Grasses at Crowder Cemetery include little bluestem and side-oats gramma, and rare plants include slender blazing star (Liatris gracilis) and prairie dock (Silphium terebinthinaceum). Dwarf chinquapin oak, which is uncommon in Tennessee, also is found there. (Reference 2.4.1-6) 2.4.1.4    Wildlife Terrestrial animal surveys conducted at the CRN Site and other areas of the Clinch River Property and at the Barge/Traffic Area spanned multiple seasons (i.e., spring, summer, fall, and winter), habitat types (e.g., mature forest, herbaceous, riparian), and detection methods (e.g.,
visual, aural, ultrasonic, traps). The resulting inventory of species documented on the Clinch River Property and the Barge/Traffic Area is therefore believed to represent the majority of species that would occur on or near the CRN Site. Most of the species observed are considered to be regionally abundant and common. (Reference 2.4.1-9) None of the animals observed during terrestrial animal surveys exhibited indicators, morphological or otherwise, that suggested impacts from exposure to an unusual environmental stress (e.g., pollutants).
Domestic animals, such as cows or goats, are not present on the CRN Site or the Barge/Traffic Area. (The potential numbers and distribution of domestic animals in areas surrounding the CRN Site are discussed in conjunction with Section 5.4.)
2.4.1.4.1    Clinch River Property TVA environmental staff performed field surveys to observe terrestrial animals on the Clinch River Property during spring and summer of 2011 (April, May, and July) and during all four seasons in 2013 (February, April, July, and October). Diurnal surveys were conducted by boat along the Clinch River arm of the Watts Bar Reservoir adjacent to the CRN Site perimeter, 2.4.1-13                              Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report noting any animal heard or seen along the bank. Diurnal surveys of the Clinch River Property also were conducted along multiple linear land transects distributed across the landscape in a manner that maximized sampling of habitat types present across the Clinch River Property.
Nocturnal surveys for singing frogs were conducted in close proximity to select water features on the CRN Site. Minnow traps, small mammal traps, and cover boards were set up and monitored to assess the presence of amphibians, small mammals, and herpetofauna, respectively. Bats were collected in mist nets at eight locations in July 2011. Acoustic monitoring equipment was used to detect and collect the calls of bats in July of 2011 and spring, summer, and fall of 2013. (Reference 2.4.1-9)
In addition to the terrestrial wildlife surveys described above, wildlife visual encounter surveys also were conducted quarterly along the Clinch River arm of the Watts Bar Reservoir in March, June, August, and October 2011 by TVA environmental staff. Surveys were centered at Clinch River mile (CRM) 15, downstream of the potential discharge location, and CRM 18.5, upstream of the potential intake location. (Reference 2.4.1-9) Transects approximately 2100 meters (m) in length were centered at each of these locations parallel to the shoreline along each bank. For each observation period, an area along each transect approximately 60 m in width (30 m inshore to 30 m offshore) was surveyed. Observed species were identified to general categories and by common name when possible, and their numbers were estimated. (Reference 2.4.1-10)
Species observed on the Clinch River Property using this combination of survey methods are identified by their common and scientific names in Table 2.4.1-4. Most of these species are regionally abundant. Although some of the observed species prefer specific habitat types, many are generalists and may occur in all habitat types on the CRN Site. Mammals observed on the Clinch River Property include the white-tailed deer (Odocoileus virginianus), coyote (Canis latrans), red fox (Vulpes vulpes), eastern gray squirrel (Sciurus carolinensis), eastern chipmunk (Tamias striatus), eastern cottontail (Sylvilagus floridanus), raccoon (Procyon lotor), Virginia opossum (Didelphis virginiana), and short-tailed shrew (Blarina brevicauda). In April 2011, roosting bats were observed in Rennies Cave, which is north of the CRN Site within the Grassy Creek HPA. Two individual bats were photographed: one was identified as a tricolored bat (Perimyotis subflavus) and the other could not be identified. Sightings of an elk (Cervus elaphus) were reported within the Clinch River Property in December 2012. The elk was a radio-collared female that migrated from Royal Blue Wildlife Management Area in Campbell County, Tennessee, where an elk restoration program has been underway for several years. A few years earlier, TWRA staff reported that a male elk was observed on the Clinch River Property. Bobcat sightings also have been reported from the Clinch River Property. (Reference 2.4.1-9)
Breeding birds observed in the wildlife surveys include the American crow (Corvus brachyrhynchos), blue jay (Cyanocitta cristata), Carolina chickadee (Poecile carolinensis),
Carolina wren (Thryothorus ludovicianus), tufted titmouse (Baeolophus bicolor), pileated woodpecker (Dryocopus pileatus), red-bellied woodpecker (Melanerpes carolinus), hairy woodpecker (Picoides villosus), wild turkey (Meleagris gallopavo), barred owl (Strix varia),
red-shouldered hawk (Buteo lineatus), Coopers hawk (Accipiter cooperii), ruby-throated 2.4.1-14                              Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report hummingbird (Archilochus colubris), yellow-billed cuckoo (Coccyzus americanus), red-eyed vireo (Vireo olivaceus), yellow-throated vireo (Vireo flavifrons), white-eyed vireo (Vireo griseus),
scarlet tanager (Piranga olivacea), chuck-wills-widow (Caprimulgus carolinensis), and whip-poor-will (Caprimulgus vociferus). Birds observed along the riparian zone include the belted kingfisher (Megaceryle alcyon), great blue heron (Ardea herodias), tree swallow (Tachycineta bicolor), and osprey (Pandion haliaetus). An osprey nest was observed on the CRN Site on a transmission line structure within a corridor that crosses the CRN Site.
(Reference 2.4.1-9) Birds observed that typically occur in riverine habitat include the great blue heron, black-crowned night heron (Nycticorax nycticorax), belted kingfisher, bald eagle (Haliaeetus leucocephalus), osprey, wood duck (Aix sponsa), Canada goose (Branta canadensis), double-crested cormorant (Phalacrocorax auritus), and swallows (Reference 2.4.1-10).
Amphibians observed on the Clinch River Property include the gray treefrog (Hyla versicolor),
American toad (Bufo americanus), green frog (Rana clamitans), and eastern narrow-mouthed toad (Gastrophryne carolinensis). Reptiles observed were the black rat snake (Elaphe obsoleta obsoleta), corn snake (Elaphe guttata guttata), and aquatic turtles, including the common snapping turtle (Chelydra serpentina), painted turtle (Chrysemys picta), river cooter (Pseudemys concinna), and Cumberland slider (Trachemys scripta troostii). (Reference 2.4.1-9) 2.4.1.4.2  Barge/Traffic Area TVA environmental staff performed field surveys to observe terrestrial animals on the Barge/Traffic Area during November 2014 and January, April, and June 2015 using methods that were essentially the same as those used on the Clinch River Property but were modified for the smaller area. Wildlife surveys were conducted for approximately one week in each of the four seasons. (Reference 2.4.1-11)
Four linear transects for wildlife surveys were established across the Barge/Traffic Area. Two transects were established within upland mature deciduous forest, one in edge habitat between wetland forest along the reservoir and an upland pine forest fragment, and one through a stand of pine trees adjacent to a transmission line ROW and large wetland. Survey techniques included Sherman traps, cover boards, and visual and aural encounters. A total of 20 Sherman traps and 16 cover boards were deployed along the four transects to survey small mammals and herpetofauna, respectively. Four minnow traps were deployed within the Barge/Traffic Area to inventory frogs and salamanders: two traps in an inlet of the reservoir in a transmission line ROW and two traps in an emergent wetland along Bear Creek Road. Anuran call surveys were conducted adjacent to two aquatic sites on the Barge/Traffic Area. Techniques for baiting and checking traps, visual and aural encounter surveys, anuran surveys, and opportunistic detections were identical to those used for terrestrial animal surveys of the Clinch River Property. Boat surveys along the Clinch River arm of the Watts Bar Reservoir previously were conducted in the vicinity of the CRN Site, including the Barge/Traffic Area, and were not repeated. Species observed on the Barge/Traffic Area using this combination of survey methods are identified by their common and scientific names in Table 2.4.1-4. (Reference 2.4.1-11) 2.4.1-15                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Visual and aural observations of terrestrial animals on the Barge/Traffic Area were very similar to terrestrial animal observations on the Clinch River Property. Most species observed are generalists and found in multiple habitats across the Barge/Traffic Area, though some are habitat specialists and observed only in specific habitat types. Examples of bird species observed included the American goldfinch (Spinus tristis), barred owl, blue jay, Carolina chickadee, Carolina wren, cedar waxwing (Bombycilla cedrorum), downy woodpecker (Picoides pubescens), eastern phoebe, eastern towhee (Pipilo erythrophthalmus), field sparrow (Spizella pusilla), golden-crowned kinglet (Regulus satrapa), hermit thrush (Catharus guttatus), northern cardinal (Cardinalis cardinalis), northern flicker (Colaptes auratus), pine warbler (Setophaga pinus), prairie warbler (Setophaga discolor), red-bellied woodpecker, red-eyed vireo, red-tailed hawk (Buteo jamaicensis), red-winged blackbird (Agelaius phoeniceus), ruby-throated hummingbird, song sparrow (Melospiza melodia), tufted titmouse, yellow-rumped warbler (Setophaga coronata), and white-eyed vireo. The belted kingfisher, great blue heron, and tree swallow were observed along the riparian corridor. A juvenile bald eagle and several ospreys were observed flying over the area. Common amphibians and reptiles observed were the American toad, southern leopard frog (Rana utricularia), pickerel frog (Rana palustris), spring peeper (Pseudacris crucifer), northern water snake (Nerodia sipedon), red-eared slider (Trachemys scripta elegans), and box turtle (Terrapene carolina carolina). Tadpoles of the upland chorus frog (Pseudacris triseriata feriarum) were observed in a wet depression of a mowed area at the northwestern corner of the Barge/Traffic Area. (Reference 2.4.1-11)
Common mammals observed in the Barge/Traffic Area included the American beaver (Castor canadensis), white-tailed deer, coyote, eastern gray squirrel, eastern chipmunk, eastern cottontail, raccoon, and Virginia opossum. Surveys specifically designed for detecting bats also were conducted in 2014 and 2015. Acoustic monitors for bats in the Barge/Traffic Area were directed at two locations on a rarely used, forested road corridor (Water Tank Road) located east of the proposed location of the eastern highway access ramp (Figure 2.1-3); across an inlet of the reservoir; and across a large wetland. (Reference 2.4.1-11) Acoustic monitor placement and acoustic analysis for these surveys followed the most current USFWS Indiana bat survey guidelines. Forest-dwelling bats and those that forage and travel in and along forests are likely to be recorded along forest corridors such as Water Tank Road, while the wetland and inlet are likely used by multiple bats for drinking and foraging. It also is likely that individual bats were detected and recorded multiple times due to repeated visits to these aquatic features. Individual bats likely visited these sites multiple times, perhaps making multiple passes in front of the monitor during a single visit, thus resulting in multiple recordings. (Reference 2.4.1-11)
The acoustic monitors detected 10 species across the Barge/Traffic Area. The most prevalent species detected were the tricolored bat, red bat (Lasiurus borealis), evening bat (Nycticeius humeralis), gray bat (Myotis grisescens), big brown bat (Eptesicus fuscusI), and silver-haired bat (Lasionycteris noctivagans). Other species recorded were the hoary bat (Lasiurus cinereus),
little brown bat (Myotis lucifugus), and northern long-eared bat (Myotis septentrionalis).
Recordings that were identified by acoustic software as the Indiana bat (Myotis sodalis) suggest this species may be present in the Barge/Traffic Area; however, visual assessment of these 2.4.1-16                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report calls determined that identification of the species based on these recordings is not definitive.
(Reference 2.4.1-11)
Terrestrial animal surveys on the Barge/Traffic Area observed a total of 117 terrestrial animal species, 13 of which were not observed on the Clinch River Property. These species were observed visually, heard, trapped, noted based on sign (e.g., scat remains), and/or acoustically detected across one or more seasons using multiple detection methods. A combined total of 190 terrestrial animal species were observed across both the Clinch River Property and the Barge/Traffic Area over the course of all terrestrial animal studies from 2011-2015. (Reference 2.4.1-11) Table 2.4.1-4 provides a master list of species for the Clinch River Property and Barge/Traffic Area.
2.4.1.5      Important Terrestrial Species According to NUREG-1555, important species include species that are federally listed as threatened or endangered, as well as species that are proposed for or candidates for federal listing. Also important are species with a state listing status or other state status due to rarity. In conjunction with agency coordination regarding listed species, TVA sent letters to the USFWS and TDEC in September 2016 requesting their concurrence with the listed species identified as important species for the site. These letters are included in Appendix A. Information provided in the consultation responses from USFWS and TDEC will be incorporated when received, and the responses will be included in Appendix A.
In addition to listed species, commercially or recreationally valuable species could be important, and nuisance species could be important, particularly if they may cause problems for operation of two or more SMRs at the CRN Site. Species also may be important if they are critical to the survival of a rare species or to the local ecosystem, or if they are indicators of potential biological effects; however, such species were not identified for the CRN Site or the Barge/Traffic Area. Thus, the important terrestrial species to be discussed below for the CRN Site and the Barge/Traffic Area include federally and state-listed species, commercially or recreationally valuable species, and nuisance species.
Field surveys of the Clinch River Property to observe and identify important plant species were conducted in 2011 and 2013 as described in Subsection 2.4.1.1.1. Field surveys of the Clinch River Property to observe and identify important animal species were conducted in 2011 and 2013 as described in Subsections 2.4.1.4 and 2.4.1.5.1. Field surveys of the Barge/Traffic Area to identify important plant species were conducted in 2015 as described in Subsection 2.4.1.1.1.
Field surveys to identify important animal species in the Barge/Traffic Area were conducted in 2014 and 2015 as described in Subsection 2.4.1.4.2. The design and extent of surveys conducted on the CRN Site, other areas of the Clinch River Property, and the Barge/Traffic Area provide approximate estimates of the numbers of these species that may occur on the CRN Site or in the Barge/Traffic Area.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.4.1.5.1  Federally Listed Species Terrestrial and wetland species with federal listing status (currently listed, proposed for listing, or candidates for listing) and recorded occurrences in Roane County, Tennessee are identified in Table 2.4.1-5. Based on a review of the TVA Regional Natural Heritage Database in November 2013, rare species potentially occur in the vicinity (i.e., within 3 to 5 mi) of the CRN Site.
(Reference 2.4.1-9) Five federally-listed threatened or endangered species and one proposed threatened species have documented occurrences in Roane County. These include two bats that are listed as endangered, one bat that is listed as threatened, two plants that are listed as threatened, and one plant that has a status of proposed threatened (Reference 2.4.1-12; Reference 2.4.1-13). None of these species have designated critical habitat in the vicinity of the CRN Site.
The two bats in Roane County that are federally listed as endangered are the gray bat (Myotis grisescens) and Indiana bat (Myotis sodalis). The bat listed as threatened is the northern long-eared bat. In 2011, habitats on the Clinch River Property were surveyed in late winter and spring to identify suitable habitat for listed bat species. Based on results of the habitat surveys, mist net surveys for listed bat species were conducted in July 2011 at eight locations throughout the Clinch River Property. In addition, acoustic monitoring using AnabatTM technology also was performed concurrent with mist net sampling at locations in close proximity to the mist net survey locations. Additional acoustic monitoring was performed at six locations on the Clinch River Property in spring, summer, and fall of 2013. (Reference 2.4.1-9) As discussed in Subsection 2.4.1.4.2, acoustic surveys for bats also were conducted in the Barge/Traffic Area in 2014 and 2015. These three bat species and the survey results for each species are discussed below.
The two plant species in Roane County that are federally-listed as threatened are American Harts-tongue fern (Asplenium scolopendrium var. americanum) and Virginia spiraea (Spiraea virginiana). The candidate for listing is the white fringeless orchid (Platanthera integrilabia). Field surveys for listed plant species on the CRN Site were performed by TVA in April and July 2011 and September 2013. Habitat suitable for these plants was not found on the Clinch River Property. (Reference 2.4.1-1) Brief descriptions of these species are provided below.
Gray Bat (Myotis grisescens)
The endangered gray bat hibernates in caves in large numbers during winter months and migrates to warmer caves to form summer maternity colonies (composed of adult females and young) or bachelor colonies (composed of adult males). The gray bat is closely associated with rivers, lakes, and other large bodies of water over which it forages for mainly aquatic insects.
The gray bat has responded positively to conservation measures, and the majority of its populations are stable or increasing. The gray bat forages over large areas, and it is known to forage along the Clinch River. Gray bats also have been detected foraging along a pond on the ORR approximately 2 mi north of the CRN Site. Summer roosting gray bats have been 2.4.1-18                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report documented in Marble Bluff Cave, located at Tennessee River Mile 578.3, approximately 9 mi (25 river mi) from the CRN Site. (Reference 2.4.1-9)
The gray bat has been reported to occur in Roane County, and it was recorded on the Clinch River Property by surveys performed by TVA in 2011 and 2013. One gray bat was captured in 2011 at a mist net location in the southwest area of the Clinch River Property, and gray bats were detected acoustically in 2011 at three other Clinch River Property locations. In 2013, gray bats were detected at all six acoustic survey locations on the Clinch River Property and were detected during every monitoring season (spring, summer, and fall), which suggest that winter and summer cave habitat exists for this species nearby. The gray bat is likely to use the area near the reservoir for foraging. (Reference 2.4.1-9) Although studies have shown that gray bats forage primarily over aquatic systems, they also would venture short distances into adjacent terrestrial habitat to forage, or they would cross terrestrial habitats to access streams, rivers, and reservoirs. (Reference 2.4.1-14)
The gray bat has been found to forage on the Clinch River Property, as documented in both mist nest and acoustic surveys. Its foraging activities are likely to occur primarily over the nearby reservoir and other riparian areas on or near the CRN Site. The gray bat may roost on the Clinch River Property; however, this has not been confirmed. All five documented caves on the Clinch River Property are located within the Grassy Creek TVA Habitat Protection Area. It is likely that the presence of the gray bat is seasonal and restricted to summer, when this species is roosting in nearby caves. Gray bats were detected at all acoustic survey locations during 2013 acoustic surveys, which suggest a minimum of six bats potentially simultaneously foraging across the Clinch River Property during the survey. Potential numbers of gray bats on the Clinch River Property during the summer may reflect a proportion of the number of roosting bats in caves in the vicinity, such as Marble Bluff Cave (approximately 9 mi away), with numbers of emerging gray bats ranging from 0 to greater than 200 across past summer surveys. Gray bats may travel as much as 80 kilometers (50 mi) of river or lake shore to forage. This suggests that gray bats foraging on the Clinch River Property may originate from multiple caves.
Approximating the number of gray bats that may be present on the CRN Site on a given night during the summer is therefore challenging. (Reference 2.4.1-9) Acoustic surveys of the Barge/Traffic Area identified gray bats foraging in that area as well (Reference 2.4.1-11).
The entire Clinch River Property was investigated for the presence of caves. Two previously documented caves, Rennies Cave and 2-Batteries Cave, are located within the Grassy Creek HPA. Two individual bats were observed roosting in Rennies Cave by archaeological surveyors in April 2011. One of these bats was identified from photos as a tricolored bat and the other bat could not be identified. TVA environmental staff have determined that neither Rennies Cave nor 2-Batteries Cave contains suitable habitat for maternity or hibernaculum use by the gray bat (or the Indiana bat or northern long-eared bat). Three additional caves near Grassy Creek were found by TVA environmental staff during surveys of the HPA. One of these features was a rock shelter, a shallow cave feature unsuitable for these species. The other two features were shallow "pit" caves with no obvious chamber suitable for bat roosting. All caves were located within the Grassy Creek HPA (Reference 2.4.1-9).

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Indiana bat (Myotis sodalis)
The endangered Indiana bat hibernates in caves and mines in winter and migrates to summer habitats in wooded areas. The large winter colonies disperse in spring, and reproductive females form smaller maternity colonies in wooded areas. Males and nonreproductive females roost in trees but typically do not roost in colonies. The range of the Indiana bat extends from the northeast through the east-central United States. The Indiana bat typically forages in semi-open forested habitats and forest edges as well as riparian areas. Suitable summer roosting habitat requires dead, dying, or living trees of sufficient size with sufficient exfoliating bark. Multiple roost sites generally are used. Primary summer roosts typically are behind the bark of large, dead trees, particularly those that are in gaps in the forest canopy or along forest edges so that they receive sufficient sun exposure. (Reference 2.4.1-15) Indiana bats have smaller summer home ranges than gray bats and forage within 2.5 mi of roost trees. Numbers of the Indiana bat are stable or decreasing throughout portions of its range due to disease (white-nose syndrome) and loss of habitat. (Reference 2.4.1-9)
The closest record of the Indiana bat to the CRN Site in the summer was a mist net capture of an adult male on the ORR in June 2013 over an inlet of Melton Hill Lake, approximately 10 mi from the CRN Site. The closest record of the Indiana bat to the CRN Site in winter was from a hibernaculum at Norris Dam Cave, approximately 27 mi to the northeast in Campbell County, Tennessee. However, no Indiana bats were observed in this cave during more recent winter surveys conducted in 2002, 2010, and 2011 to 2013. The closest records of summer roosting of the Indiana bat are from 27 to 29 mi to the southeast in the Cherokee National Forest (Monroe County, Tennessee). Cave surveys of the Clinch River Property by TVA environmental staff did not find caves that contain suitable habitat for hibernaculum use by the Indiana bat. (Reference 2.4.1-9)
Although the Indiana bat has not been previously reported to occur in Roane County, it was recorded on the Clinch River Property by acoustic surveys performed in the spring and summer of 2013. To assess the presence of suitable habitat for the Indiana bat on the Clinch River Property, surveys specifically designed to identify habitat suitable for summer roosting by the Indiana bat were conducted in the spring of 2011. Habitat survey results indicated potentially suitable summer roosting habitat within the forested areas in the northern half of the Clinch River Property. TVA environmental staff subsequently conducted mist net and acoustical surveys of the Clinch River Property. Although no Indiana bats were captured or detected on the Clinch River Property in 2011, they were detected acoustically in 2013 at five of six locations.
The mist net capture of an Indiana bat in June 2013 on the ORR and the 2013 acoustic detections on the Clinch River Property support the potential presence of the Indiana bat at the Clinch River Property during spring and summer months (April-August). Moderate to high quality roosting habitat for the Indiana bat occurs on the northern half of the Clinch River Property.
However, no roost trees have been documented on the Clinch River Property, which makes it difficult to estimate numbers of this species on the Clinch River Property or the CRN Site. Given the rarity of the Indiana bat, numbers would be expected to be low to none in any given year during the warm, non-hibernating season. (Reference 2.4.1-9) Acoustic surveys of the 2.4.1-20                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Barge/Traffic Area potentially identified Indiana bats foraging in that area as well. However, visual assessment of the acoustic recordings determined that the identification of the Indiana bat based on software analysis of the recordings is not definitive. (Reference 2.4.1-11)
Northern Long-eared Bat (Myotis septentrionalis)
The northern long-eared bat was listed by the USFWS as threatened in May 2015 (Reference 2.4.1-16). The decision to list the northern long-eared bat as federally threatened was primarily due to the threat posed to the species by white-nose syndrome, a fungal disease that has resulted in substantial mortality to the species, particularly in the northeastern United States.
Although declines in populations of this species have been observed in the southeast region, the declines have not been as dramatic as those in the northeast. (Reference 2.4.1-9)
One northern long-eared bat was captured by mist net in the southern half of the Clinch River Property in summer of 2011. This species was detected acoustically at three locations in the northern half of the Clinch River Property in spring and summer of 2013. It also was captured on the ORR (10 mi from the CRN Site) during mist net surveys in 2013. These detections and their locations indicate the presence of the northern long-eared bat in association with forested areas and aquatic features on the Clinch River Property. The northern long-eared bat hibernates in caves during winter and migrates to roost on the landscape during summer. Although studies of their use of habitat during summer are few or ongoing, available data suggest that summer habitat use by the northern long-eared bat is probably similar to that of the Indiana bat.
(Reference 2.4.1-9) Cave surveys of the Clinch River Property by TVA environmental staff did not find caves that contain suitable habitat for hibernaculum use by the northern long-eared bat.
Northern long-eared bats have smaller summer home ranges than gray bats and forage within 1.5 mi of roost trees. No occupied roost trees have been documented on Clinch River Property, which makes an estimate of numbers of this species on Clinch River Property difficult. Although southeastern populations have declined, the northern long-eared bat is a relatively common species in this region, and its presence at the Clinch River Property would be expected during the warm, non-hibernating season. Populations of the northern long-eared bat in this region are likely to be larger than those of the Indiana bat. These regional population relationships are likely to be reflected in the numbers of individual bats that occur on the Clinch River Property (i.e., numbers of individuals of the northern long-eared bat are likely greater than those of the Indiana bat). (Reference 2.4.1-9) Acoustic surveys of the Barge/Traffic Area identified northern long-eared bats foraging in that area as well (Reference 2.4.1-11).
American Harts-tongue Fern (Asplenium scolopendrium var. americanum)
American Harts-tongue fern, which is federally listed as threatened, has large, glossy, unserrated fronds from 20 centimeters (cm) to 40 cm long. The typical habitat of American Harts-tongue fern is shaded, moist, deciduous forests where the fern grows from small cracks in limestone boulders and ledges, which provide the high magnesium levels it requires.
(Reference 2.4.1-17) This fern usually is found in areas with outcrops of dolomitic limestone, 2.4.1-21                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report including gorges and limestone sinkholes in mature hardwood forests. It needs the high humidity and deep shade provided by mature forest canopies or overhanging rock cliffs. Its range extends from Alabama to Canada; however, its distribution within this range is discrete and very limited. Populations usually are small due to its specific habitat requirements.
American Harts-tongue fern is threatened by logging, which reduces shade and humidity, and also by quarrying, recreation, and residential development. (Reference 2.4.1-18) The report of American Harts-tongue fern in Roane County is a historical record and the population is thought to be extirpated at the Roane County location where it was previously recorded. The nearest known extant population is found in a sinkhole near South Pittsburg, Tennessee. (Reference 2.4.1-19) American Harts-tongue fern was not observed in field surveys of the Clinch River Property, and its preferred habitat was not found to be present (Reference 2.4.1-1).
Virginia Spiraea (Spiraea virginiana)
Virginia spiraea, which is federally listed as threatened, is a perennial shrub of the rose family that has dark gray mature stems with creamy white flowers in closely packed bunches. The majority of the current populations of this shrub contain only a small number of clumps. The typical habitat of Virginia spiraea is on the scoured banks of high-gradient streams or on meanders, point bars, natural levees, and braided features of lower-gradient stream segments.
The soils in which Virginia spirea is found typically are sandy, silty, or clayey, and it occurs at elevations ranging from 1000 to 2400 ft. The range of Virginia spiraea is the southern Blue Ridge Mountains or Appalachian plateau in Alabama, Tennessee, Kentucky, Ohio, West Virginia, Virginia, North Carolina, and Georgia. A critical requirement for sustaining this plant seems to be removal of woody competition by erosion. Virginia spiraea is threatened by factors such as impoundments, road maintenance, beaver damage, off-road vehicle use, deer browse, non-native plant species, and pollution. (Reference 2.4.1-20) Virginia spiraea was not observed in field surveys of the Clinch River Property, and its preferred habitat was not found to be present (Reference 2.4.1-21; Reference 2.4.1-1).
White Fringeless Orchid (Platanthera integrilabia)
The status of white fringeless orchid (also known as monkey-face orchid) was changed from a candidate for federal listing to proposed for listing as threatened in September 2015 (Federal Register [Vol 80, No 178, 9/15/15]). White fringeless orchid is a perennial herb that blooms from late July to early September. The typical habitat of white fringeless orchid is partially shaded, flat, boggy areas at the heads of streams or seepage slopes. This orchid is usually found in acidic muck or sand in association with sphagnum moss and cinnamon fern, netted chain fern, and New York fern. The white fringeless orchid is uncommon throughout its range in the southeastern and south central United States. It is threatened by habitat modification, mainly alteration of hydrology. (Reference 2.4.1-22) White fringeless orchid was not observed in field surveys of the Clinch River Property, and its preferred habitat was not found to be present (Reference 2.4.1-1; Reference 2.4.1-21).
2.4.1-22                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.4.1.5.2    State-Listed Species Forty-eight terrestrial or wetland species with a state listing status or other state protected status have recorded occurrences in Roane County (Table 2.4.1-5). The animal species with state status include four birds, nine mammals, two reptiles, and one amphibian that are state-listed as threatened or endangered or are deemed in need of management. The plant species with state status include 30 species that are state-listed as endangered, threatened, or of special concern; one species of special concern due to commercial exploitation; and one species that is of special concern and possibly extirpated. (Reference 2.4.1-12) Four of these state-listed animals and plants also are federally listed, and one is proposed for federal listing as threatened. In Subsection 2.4.1.5.1, the animals with federal listing status were discussed and found to have the potential to occur on the Clinch River Property, and the plants with federal listing status were eliminated from further evaluation because field surveys did not find them on the Clinch River Property and suitable habitat was not present on the Clinch River Property.
The remaining species that have a state listing status or other protective status were further considered with regard to their potential to occur on the CRN Site given the proximity of their recorded occurrences and their habitat requirements. Table 2.4.1-6 identifies the species with state status and recorded occurrences in Roane County, briefly describes their characteristic habitats, and denotes the subset of species that have recorded occurrences within 6 mi of the CRN Site. Based on a review of the TVA Regional Natural Heritage Database in November 2013 and observation of Indiana bats and bald eagles during wildlife surveys at the CRN Site, occurrences of 27 species with a state listing status or other state protected status have been recorded within 6 mi of the CRN Site. Two of these animal species, the gray bat and Indiana bat, are federally listed and were discussed in Subsection 2.4.1.5.1. One of these plant species is of concern because it is commercially exploited. Of the remaining 24 species with state status and recorded occurrences within 6 mi, seven are animals and 17 are plants.
Four state-status animal species were observed at the CRN Site during wildlife surveys: the gray bat, Indiana bat, sharp-shinned hawk (Accipiter striatus), and bald eagle (Haliaeetus leucocephalus) (Reference 2.4.1-9). Field surveys of the CRN Site to search for possible rare plant species found that no state-status plant species occur on the CRN Site. Two state-status plant species were observed during field surveys on the Clinch River Property within the Grassy Creek HPA: spreading false foxglove (Aureolaria patula) and American ginseng (Panax quinquefolius) (Reference 2.4.1-1). Although the Clinch River Property potentially could provide suitable habitat for many of the terrestrial and wetland species with state status included in Table 2.4.1-6, only these four animal species and two plant species were observed during recent or earlier surveys of the Clinch River Property (Reference 2.4.1-1; Reference 2.4.1-9).
In the Barge/Traffic Area, state-status animal species observed include the gray bat (endangered), Indiana bat (endangered), and bald eagle (in need of management) (Reference 2.4.1-11). Two state-status plants have been previously reported to occur (most recently in 2000) in a small portion of the southern part of the Barge/Traffic Area: spreading false foxglove 2.4.1-23                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report and shining ladies-tresses (Spiranthes lucida). However, field surveys of the Barge/Traffic Area in 2015 did not find these plants to be present. (Reference 2.4.1-3)
Of the four state-status animal species observed on the Clinch River Property, the two species not discussed as federally listed species in Subsection 2.4.1.5.1 are the sharp-shinned hawk and bald eagle. These two birds and the two plants are briefly discussed below.
Sharp-Shinned Hawk (Accipiter striatus)
The sharp-shinned hawk has a state status of in need of management. This small hawk inhabits forest and open woodland where it preys mainly on small birds. In eastern North America, its breeding habitat extends from eastern Canada south to northern Alabama, with the greatest nesting densities occurring in eastern Canada. Young, dense, mixed or coniferous woodlands are preferred for nesting. (Reference 2.4.1-23) The sharp-shinned hawk has been observed on the ORR during its breeding season. Marginally suitable habitat is available for this species within the upland ridge and valley forest habitat in the northern half of the Clinch River Property.
A sharp-shinned hawk was observed at the CRN Site in winter during a 2011 wildlife survey along the Clinch River arm of Watts Bar Reservoir. (Reference 2.4.1-9)
Bald Eagle (Haliaeetus leucocephalus)
Although no longer federally listed, the bald eagle remains federally protected by the Bald and Golden Eagle Protection Act, and it is designated by the State of Tennessee as in need of management. The bald eagle has increased in numbers in east Tennessee in the past decade.
It builds large nests in trees near reservoirs and rivers, and numerous nests are present along Watts Bar Reservoir. The bald eagle also may occur in nearby forested habitats. The closest documented nest is approximately 8 mi from the CRN Site on Watts Bar Reservoir. Bald eagles were not observed during any of the field investigations conducted by TVA environmental staff on the CRN Site in 2011 or 2013. However, TVA environmental staff did observe bald eagles in flight in 2013 during their quarterly visual encounter surveys along the Clinch River at the CRN Site. (Reference 2.4.1-9) Also, a juvenile bald eagle was observed flying over the Barge/Traffic Area during wildlife surveys (Reference 2.4.1-11).
Spreading False-Foxglove (Aureolaria patula)
Spreading false-foxglove has a state status of special concern. It is a perennial member of the figwort family that is parasitic on the roots of oaks. It grows on steep, partially shaded, calcareous slopes above rivers and large streams, often within a few feet of the water. It flowers from August through the first frost. (Reference 2.4.1-1)
American Ginseng (Panax quinquefolius)
American ginseng has a state status of special concern - commercially exploited. This herb is commercially exploited for the purported medicinal value of its roots. Collection of ginseng is regulated by the State of Tennessee through the Ginseng Dealer Registration Act of 1983 and 2.4.1-24                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report the Ginseng Harvest Season Act of 1985. Ginseng prefers mesic habitats and flowers from May to July, with fruits ripening later in summer. (Reference 2.4.1-1) 2.4.1.5.3    Species of Commercial or Recreational Value As discussed in Subsection 2.4.1.5.2, American ginseng is a plant species of commercial value that occurs on the Clinch River Property. The populations of American ginseng on the Clinch River Property are within the Grassy Creek HPA and are not available for commercial harvesting (Reference 2.4.1-1).
Terrestrial wildlife species that are hunted recreationally in the vicinity occur on the Clinch River Property and the Barge/Traffic Area, including the white-tailed deer, gray squirrel, eastern cottontail, raccoon, Canada goose, wood duck, and wild turkey. The Oak Ridge State WMA is located primarily on the ORR and is managed by the TWRA for hunting of small and large game. The Clinch River Property is adjacent to the WMA but is not within the area, and hunting is not allowed on the Clinch River Property. The Barge/Traffic Area is within the WMA and hunting is allowed in the area.
2.4.1.5.4    Nuisance Species Terrestrial nuisance species typically are invasive species that are non-native and likely to cause economic and/or environmental harm. These species also are described as alien, non-indigenous, exotic, or undesirable species. (474 Tennessee Wildlife Resources Agency 2008)
Nuisance animal species observed on the Clinch River Property during wildlife surveys conducted in 2011 and 2013 were the European starling (Sturnus vulgaris) and rock pigeon (Columba livia). The American beaver (Castor canadensis), which is native but also can be a nuisance species if it destroys trees or causes flooding, also was observed on the Clinch River Property. (Reference 2.4.1-9) Nuisance plant species are much more numerous on the Clinch River Property and include trees, shrubs, vines, grasses, and forbs. Much of the Clinch River Property was extensively altered during site preparation for the CRBRP, resulting in the introduction and spread of invasive, non-native plant species on the Clinch River Property.
(Reference 2.4.1-1) Executive Order 13112, issued in 1999, defines an invasive species as an alien species (not native to the region or area) whose introduction causes or is likely to cause economic or environmental harm or harm to human health. (Reference 2.4.1-24) Invasive plants are robust and lack the natural predators and diseases that tend to keep native plants in natural balance. Invasive plants can reduce forest productivity, hinder forest use and management activities, and degrade diversity and wildlife habitat. Some invasive plants have been introduced into this country accidentally, but most were brought here as ornamentals or for livestock forage.
(Reference 2.4.1-1) Common nuisance species of plants occurring on the Clinch River Property include the following:
* Japanese honeysuckle (Lonicera japonica) 2.4.1-25                              Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* Chinese privet (Ligustrum sinense)
* Johnsons grass (Sorghum halepense)
* Multiflora rose (Rosa multiflora)
* Autumn olive (Elaeagnus umbellata)
* Chinese (sericea) lespedeza (Lespedeza cuneata)
* Japanese stilt grass (Nepalese browntop) (Microstegium vimineum)
* Mimosa (Albizia julibrissin) (Reference 2.4.1-1)
Japanese honeysuckle, Chinese privet, Chinese lespedeza, and Japanese stilt grass also were observed on the Barge/Traffic Area (Reference 2.4.1-3). These nuisance species have the potential to spread rapidly and displace native vegetation, and they are considered a severe threat in Tennessee. No federal noxious weeds (plants designated by the United States Department of Agriculture as potentially damaging to agriculture, natural resources, public health, or the environment [7 USC 7701 et seq.]) were observed during field surveys of the Clinch River Property. (Reference 2.4.1-1) 2.4.1.6      Transmission Corridor Habitats and Species Two transmission line corridors currently traverse the CRN Site: a 161-kV line that crosses the reservoir at the southeastern tip of the peninsula and extends to the northwestern corner of the CRN Site, and a 500-kV line that crosses the reservoir and the western boundary of the CRN Site and extends northeast across the widest part of the CRN Site (Figure 2.2-1). The 500-kV line continues approximately 5 mi northeast to the Bethel Valley substation. The only new transmission line proposed for construction at a location off the CRN Site is a 69-kV underground line to be installed within the existing 500-kV ROW between the CRN Site and the Bethel Valley substation. Within the CRN Site, an approximately 1.2-mi segment of the 161-kV line is to be re-routed from its current alignment. The new 161-kV ROW extends north from the reservoir parallel to the shoreline before turning northwest and connecting to the existing ROW slightly northwest of where it crosses the 500-kV ROW. The new 161-kV ROW overlaps areas to be cleared for facility construction except for approximately 1200 ft at the southern end of the new ROW. Subsection 2.4.1.1 describes the vegetation typical of the herbaceous/grassland community on the CRN Site, which is maintained within the ROWs by control of woody vegetation under the transmission lines. A similar herbaceous community is maintained within the 5-mi segment of the 500-kV ROW in which the installation of a 69-kV underground transmission is planned. The terrestrial habitats within this ROW are not known to include wetlands or occurrences of federally or state-listed species.
Installation of a 69-kV underground transmission line is planned within the approximately 5-mi segment of the existing 500-kV ROW that extends northeast from the CRN Site to the Bethel Valley substation. Installation of the proposed underground transmission line potentially could affect terrestrial plants within the existing ROW. The vegetation within the ROW is actively 2.4.1-26                              Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report maintained by TVA as an herbaceous community, which includes plant species and habitat for animal species such as those described above for the CRN Site and Barge/Traffic Area.
Federally or state-listed plant species are not known to occur in the terrestrial communities within this ROW. Listed animal species, such as bats, potentially could forage in these open corridor habitats within the ROWs.
As discussed in Subsections 2.2.3 and 3.7.3.8, segments of the transmission system outside the CRN Site (other than the segment containing the 69-kV underground line discussed above) would require modifications involving uprating, reconductoring, or rebuilding. However, additional ROWs would not be established, cleared, or developed. The lines that include segments or structures that may need to be modified are overlaid on a map of regional land cover types in Figure 2.2-7. The vegetation communities within the ROWs for these lines are actively maintained by TVA as predominantly herbaceous communities consisting of plant and animal species such as those described above for such communities on the CRN Site and the Barge/Traffic Area. Based on TVAs Natural Heritage database, Table 2.4.1-7 identifies the biological resources that have been identified as potentially occurring on or near the ROWs for these lines. These resources include important terrestrial habitats such as state parks, state forests, and wildlife management areas; wetlands; and federal and state listed terrestrial species (Indiana bat, northern long-eared bat, and plants).

Potentially affected aquatic resources include reservoirs, ponds, and streams on and in the vicinity of the CRN Site. Wetlands and riparian habitats are discussed in conjunction with terrestrial ecology in Subsection 2.4.1. This subsection describes the ecological characteristics of the aquatic resources potentially affected by the Clinch River (CR) SMR Project.
2.4.2.1 Aquatic Habitats The CRN Site is located between approximately Clinch River mile (CRM) 14.5 and CRM 19 (Reference 2.4.2-1). The proposed location of the condenser cooling water intake is at approximately CRM 17.9, and the proposed location of the cooling water discharge is near CRM15.5. These locations are shown in Figure 2.1-3.
Tennessee Valley Authoritys (TVAs) Watts Bar Dam was built in 1942 at Tennessee River mile (TRM) 529.9 to create the Watts Bar Reservoir. This dam effectively impounded the portion of the Clinch River that flows past the CRN Site; accordingly, this reach of the Clinch River is considered part of Watts Bar Reservoir. (Reference 2.4.2-2) TVAs Melton Hill Dam, which was completed in 1963, is 5.2 miles (mi) upstream of the proposed cooling water intake structure for the CRN Site. Although Melton Hill Reservoir is a run-of-river reservoir that does not hold water long-term, this dam also affects water flow rates past the CRN Site. Releases from Fort Loudoun Dam and Watts Bar Dam downstream also can influence water velocity adjacent to the CRN Site. (Reference 2.4.2-3)
The aquatic habitats with the potential to be affected by the CR SMR Project include the Clinch River arm of the Watts Bar Reservoir, Melton Hill Reservoir, and streams and ponds on the CRN Site. Watts Bar Reservoir would be directly affected by water withdrawals and discharges.
Melton Hill Reservoir may be affected indirectly through changes in water management associated with downstream withdrawals for the CR SMR Project. Ponds and streams on or near the CRN Site may be directly affected if they are located within areas required for construction or operation of two or more SMRs. The ecological characteristics of these potentially affected water bodies are described below.
2.4.2.1.1    Clinch River Arm of the Watts Bar Reservoir TVA assesses the ecological health of its reservoirs through periodic sampling conducted historically under its Vital Signs Monitoring Program and currently under ongoing ecological health and compliance monitoring programs. The programs use multi-metric evaluation techniques to assess trends in aquatic resources and overall conditions in the reservoirs. These monitoring activities focus on:
2.4.2-1                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* Physical and chemical characteristics of the water
* Physical and chemical characteristics of the sediment
* Fish community sampling
* Benthic macroinvertebrate community sampling (Reference 2.4.2-4)
TVA monitors four locations on the Watts Bar Reservoir, usually on a 2-year (yr) cycle.
Monitoring occurred in even-numbered years beginning in 1994, with an additional monitoring event in 2009. The four monitoring locations were: the forebay area of deep water near the dam, the middle part of the reservoir, and the riverine areas at the extreme upper ends of the reservoir in the Tennessee River and the Clinch River, called the Tennessee and Clinch inflow locations. (Reference 2.4.2-5) The Clinch inflow location is at CRM 22 below Melton Hill Dam.
To obtain seasonal data specifically from the reach of the Watts Bar Reservoir adjacent to the CRN Site, TVA initiated additional studies in 2011 to characterize baseline conditions of the aquatic habitats and communities in the reservoir immediately upstream and downstream of the CRN Site (Reference 2.4.2-6).
Physical and Chemical Characteristics The physical and chemical characteristics of the water body affect the aquatic habitats and ecological communities present in the Clinch River arm of the Watts Bar Reservoir adjacent to the CRN Site. These characteristics are discussed in more detail in Subsection 2.3.3. Water quality and sediment quality parameters were measured in 2011, 2012, and 2013 as part of the preapplication monitoring study of aquatic habitats of the Watts Bar Reservoir in the area of the CRN Site. Water quality samples were taken at CRMs 18.5, 19.7, and 22.0 (upstream), and at CRM 15.5 (downstream). The sample analyses included metals, radionuclides (gross alpha, gross beta, radium-226, and radium-228), nutrients (Kjeldahl nitrogen, nitrate plus nitrite-nitrogen, ammonia-nitrogen, total phosphorus, and orthophosphate), total organic carbon (TOC), alkalinity, hardness, water clarity (turbidity and suspended solids), dissolved solids, and other constituents. Additionally, parameters such as water temperature, dissolved oxygen (DO),
conductivity, and pH were measured. (Reference 2.4.2-7) Surface water sample results for the Clinch River arm of the Watts Bar Reservoir upstream and downstream of the CRN Site indicate that TDECs most stringent numeric water quality criteria are being met. In addition, the results of stormwater sampling indicate that site runoff would not have a significant impact on water quality. (Reference 2.4.2-7)
Water quality in the vicinity of the CRN Site is influenced by Melton Hill Dam and Norris Dam and the water quality of the inflow to Melton Hill Reservoir. Consistent with the geology of the area, water of the Clinch River arm of Watts Bar Reservoir was slightly alkaline, moderately hard, and well buffered. Nutrient concentrations were relatively high for nitrogen and moderate to low for phosphorus. The low phosphorus levels could limit phytoplankton growth and abundance. Maximum water temperatures in summer, near 72 degrees Fahrenheit (&deg;F) in June and July, were well below the State of Tennessee maximum temperature criterion of 86.9&deg;F.
2.4.2-2                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report The water column tended to be well mixed, though appreciable vertical gradients in oxygen were observed in July. DO concentrations often varied spatially about 1.0 to 1.5 milligrams per liter (mg/L). Several water quality parameters varied seasonally in response to variations in rainfall and runoff as well as processes in the reservoir related to dam operations.
Concentrations of metals in water were below maximum concentrations established by the State of Tennessee for protection of aquatic life. (Reference 2.4.2-6) As discussed in Subsection 2.3.1.1.2.7, daily thermal gradients were documented to occur during summer due to surficial warming during the hottest time of the day. However, the warmer surface water was then either flushed out by daily dam releases from Melton Hill Dam, or its heat dissipated with nighttime atmospheric cooling.
Physical and chemical characteristics of the Clinch River arm of Watts Bar Reservoir resulting from historical human activities in the area have affected aquatic habitats and ecological communities. The hydrological characteristics of the Clinch River arm of the Watts Bar Reservoir near of the CRN Site were changed by the construction of Norris Dam on the Clinch River in 1936, Watts Bar Dam on the Tennessee River in 1942, and Melton Hill Dam on the Clinch River in 1963. (Reference 2.4.2-4) Dams create impoundments that can alter water quality, resulting in effects such as excessive nutrient levels, accumulation of sediment, and growth of aquatic plants. The altered flow pattern can change the physical character of the channel morphology and substrate composition. These changes affect the types of habitats present and the chemical characteristics of the water. Dams also impede the movement of aquatic organisms and reduce the likelihood of reproductive dispersal. These dam-induced mechanisms change the composition of the ecological communities present. (Reference 2.4.2-8) The Clinch River arm of Watts Bar Reservoir also has been affected by the historical release of pollutants. For example, contaminants released from the Oak Ridge National Laboratory (ORNL) have resulted in sediment toxicity issues between White Oak Creek (at CRM 21, upstream of the CRN Site) and Watts Bar Dam (TRM 530) that may have contributed to mussel declines in this area. (Reference 2.4.2-4)
In addition to water quality, sediment quality was assessed at three locations (CRMs 15.5, 18.5, and 22.0) during the 2011 surveys. Sediment samples were analyzed for pesticides, polychlorinated biphenyls (PCBs), and metals. Metals concentrations were below U.S.
Environmental Protection Agency (EPA) Region 4 ecological screening levels for sediment, and pesticides and PCBs were not detected in the sediment samples collected near the CRN Site.
Sediments at these locations contained lower metals concentrations than typically found in more lacustrine environments within TVA reservoirs. Substrate composition was characterized at eight downstream transects and eight upstream transects. Sand was the dominant substrate downstream, followed by cobble, silt, and gravel. Clay was the dominant substrate upstream, followed by gravel, cobble, and bedrock. (Reference 2.4.2-6)
Although contaminants were not detected in sediments near the CRN Site, the Division of Water Pollution Control of the Tennessee Department of Environment and Conservation (TDEC) has issued fish consumption advisories for Watts Bar Reservoir due to PCBs and for Melton Hill Reservoir due to PCBs and chlordane. These fish consumption advisories were issued because 2.4.2-3                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report these contaminants were detected in sediments in other areas of these reservoirs. (Reference 2.4.2-6)
Biological Communities Since 1990 TVA has systematically monitored the aquatic biological communities in its reservoirs as part of the former Vital Signs Monitoring Program and its ongoing ecological health and compliance monitoring programs. The Clinch River inflow area of Watts Bar Reservoir upstream of the CRN Site has been monitored under this program. (Reference 2.4.2-4) To obtain additional data specifically from the reach of Watts Bar Reservoir adjacent to the CRN Site, TVA initiated additional studies in 2011 to characterize the aquatic communities occurring in the reservoir immediately upstream and downstream of the CRN Site. These 2011 studies were designed to evaluate the diversity, abundance, and condition of resident fish, benthic macroinvertebrate, and plankton communities in the vicinity of the CRN Site in order to establish baseline conditions existing prior to construction and operation of two or more SMRs. During these studies of aquatic habitat, submerged aquatic vegetation (macrophytes) was not observed at either of the study locations. (Reference 2.4.2-6)
Fish Community Fish communities are used to evaluate ecological conditions because of their importance in the aquatic food web and because fish life cycles are long enough to integrate conditions over time.
Impoundments have affected the characteristics of the fish community in the Clinch River arm of Watts Bar Reservoir (Reference 2.4.2-6). The cool water of Melton Hill Reservoir is released to Watts Bar Reservoir at CRM 23.1, approximately 4.1 mi upstream of the CRN Site. Although the water warms with distance below the Melton Hill Dam, its relatively cooler temperatures may limit fish species diversity and abundance downstream (Reference 2.4.2-6). To characterize the fish community currently present in the reach of Watts Bar Reservoir adjacent to the CRN Site, TVA implemented fisheries studies there in 2011. In conjunction with the Vital Signs Monitoring Program, TVA previously developed a fisheries monitoring tool, the Reservoir Fish Assemblage Index (RFAI) (Reference 2.4.2-4). The RFAI was thoroughly tested on TVA reservoirs and other reservoirs and published in peer-reviewed literature. The RFAI was used in the 2011 aquatic habitat study to characterize the fish community in the vicinity of the CRN Site. (Reference 2.4.2-6)
Fish Community Characterization To characterize the fish community in the Clinch River arm of Watts Bar Reservoir at the CRN Site, TVA selected two fish sampling locations: one located downstream of the CRN Site between CRMs 14 and 16 (referred to as location CRM 15.0), and one located upstream of the CRN Site between CRMs 18 and 19.8 (referred to as location CRM 18.5). Sampling by electrofishing and gill netting was conducted in February, May, July, and October of 2011 to document seasonal variation in fish community composition. The fish collected were identified 2.4.2-4                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report by species, counted, and examined for anomalies such as disease, deformations, parasites, or hybridization. The resulting data were analyzed using RFAI methodology. (Reference 2.4.2-6)
The RFAI uses 12 fish community metrics from four general categories: Species Richness (numbers of species) and Composition; Trophic Composition; Abundance; and Fish Health.
Individual species can be utilized for more than one metric. Together, these 12 metrics provide a balanced evaluation of fish community integrity. (Reference 2.4.2-6) The 12 metrics, grouped by category, are summarized below:
* Species Richness and Composition Total number of indigenous species (greater than 29 required for highest score): Greater numbers of indigenous species are considered representative of a healthier aquatic ecosystem. As conditions degrade, numbers of species in an area decline.
Number of centrarchid species (greater than four required for highest score): Sunfish species (excluding black basses) are invertivores, and a high diversity of this group is indicative of reduced siltation and suitable sediment quality in littoral areas.
Number of benthic invertivore species (greater than seven required for highest score):
Due to the special dietary requirements of this species group and the limitations of their food source in degraded environments, numbers of benthic invertivore species increase with better environmental quality.
Number of intolerant species (greater than four required for highest score): A group composed of species that are particularly intolerant of physical, chemical, and thermal habitat degradation. Higher numbers of intolerant species suggest the presence of fewer environmental stressors.
Percentage of tolerant individuals (less than 31 percent of electrofishing samples and less than 16 percent of gill net samples required for highest score): This metric signifies poorer water quality with increasing percentages of individuals tolerant of degraded conditions.
Percent dominance by one species (less than 20 percent of electrofishing samples and less than 14 percent of gill net samples required for highest score): Ecological quality is considered reduced if one species inordinately dominates the resident fish community.
Percentage of non-indigenous species (less than 3 percent of electrofishing samples and less than 5 percent of gill net samples required for highest score): This metric is based on the assumption that non-indigenous species reduce the quality of resident fish communities.
Number of top carnivore species (greater than seven required for highest score): Higher diversity of piscivores is indicative of the availability of forage species and the presence of suitable habitat.
2.4.2-5                                    Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* Trophic Composition Percentage of individuals as top carnivores (greater than 11 percent of electrofishing samples and greater than 52 percent of gill net samples required for highest score): This metric is a measure of the functional aspect of top carnivores that feed on lower trophic levels.
Percentage of individuals as omnivores (less than 22 percent of electrofishing samples and less than 23 percent of gill net samples required for highest score): Omnivores are less sensitive to environmental stresses due to their ability to vary their diets. As trophic links are disrupted due to degraded conditions, specialist species such as insectivores decline while opportunistic, omnivorous species increase in relative abundance.
* Abundance Average number per run (number of individuals) (greater than 210 from electrofishing samples and greater than 24 from gill net samples required for highest score): This metric is based on the assumption that high-quality fish assemblages support large numbers of individuals.
* Fish Health Percentage of individuals with anomalies (less than 2 percent of gill net and electrofishing samples required for highest score): Occurrences of diseases, lesions, tumors, external parasites, deformities, blindness, and natural hybridization are noted. A higher percentage of individuals exhibiting such conditions can indicate poor environmental conditions. (Reference 2.4.2-6)
The fish species collected from the Clinch River arm of Watts Bar Reservoir in the 2011 study are listed in Table 2.4.2-1. The trophic level for each species is shown, indigenous species are identified, and those species designated as tolerant and intolerant also are identified. The RFAI scores for each location in each season and the associated ecological health ratings for the fish community are summarized in Table 2.4.2-2.
The overall RFAI scores resulted in an ecological health rating for the fish community of fair for each season at the downstream location. The ecological health rating for the fish community at the upstream location was fair for winter, summer, and autumn, and good for spring. These scores are similar to other assessment locations on the Clinch River downstream of Melton Hill Dam. (Reference 2.4.2-6)
Overall RFAI ratings for each season for the downstream and upstream sampling locations were similar. RFAI scores during each of the four seasons differed by four points or less between the two sampling sites. RFAI scores have an intrinsic variability of plus or minus three points. This variability comes from various sources, including:
* Annual variations in air temperature and stream flow 2.4.2-6                                      Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* Variations in pollutant loadings from nonpoint sources
* Changes in habitat, such as extent and density of aquatic vegetation
* Natural population cycles and movements of the species being measured In addition, nearly any practical measurement, lethal or non-lethal, of a biological community is a sample rather than a measurement of the entire population. This variability due to methods must be considered when comparing scores between sampling locations. (Reference 2.4.2-6)
Both sampling locations received low scores for the metric average number per run for both electrofishing and gill net samples each season. Cool water temperatures from Norris Dam releases upstream may limit overall productivity, thus reducing abundance of some species in this portion of the Clinch River arm of Watts Bar Reservoir. Although catch rates were low, species diversity was relatively high at both locations. Averages of 33 (28 indigenous) and 36 species (31 indigenous) were collected at the downstream and upstream locations, respectively.
Distinct differences in trophic guild composition of the fish community were evident between locations during each season. The upstream location contained higher proportions of omnivores and fewer proportions of insectivores than the downstream location in each season. Proportions of top carnivores were higher at the upstream location during spring but were similar at the two locations during other seasons. The downstream location had a much higher proportion of benthic invertivores during autumn. (Reference 2.4.2-6)
Thermally sensitive species were defined as those having an upper lethal limit of water temperatures greater than or equal to 90&deg;F. Thermally sensitive species collected in the 2011 sampling are identified in Table 2.4.2-1. On average, two thermally sensitive species were present during all four seasons at both sampling locations. All fish species collected were considered Representative Important Species because they were used to obtain an overall RFAI score. Representative Important Species are defined by the EPA as those species that are representative in terms of their biological requirements of a balanced, indigenous community of fish, shellfish, and wildlife in the body of water into which a discharge is released.
(Reference 2.4.2-6)
Fish Eggs and Larvae Also in 2011, TVA investigated fish eggs and larvae in Watts Bar Reservoir at the CRN Site to assess the temporal occurrence, abundance, and species composition of ichthyoplankton in that part of the reservoir. Samples were collected adjacent to the CRN Site at an upstream location at CRM 18 and a downstream location at CRM 15.5. Eight samples were collected from each location at the following frequencies: once in February 2011, weekly from March through August 2011, and once a month from September 2011 through January 2012. (Reference 2.4.2-3) The sampling frequency was selected to capture seasonal spawning activity of fishes. Thus, sampling was performed weekly during March through August when the majority of spawning occurs and monthly from September through February when little to no spawning occurs. Each sampling event included the collection of eight samples (four day and four night) along a 2.4.2-7                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report transect at each location. The four day and four night samples were collected along the transects at mid-channel full stratum, mid-channel bottom only, right descending bank, and left descending bank. The species abundance data also were used with sample volume data to calculate species-specific densities of fish eggs and larvae in the water column. (Reference 2.4.2-3)
The total numbers of fish eggs and larvae collected at the upstream and downstream locations and the percentage composition of the samples represented by each taxon are summarized in Table 2.4.2-3. The taxa identified in the samples are organized in the table by family. The families represented in the egg and larvae samples and the principal species identified from each family include the following (Percidae and Polyodontidae constitute less than 1 percent of the total eggs or larvae collected):
* Atherinopsidae (silversides, predominantly Mississippi silversides)
* Catostomidae (buffalofishes, carpsuckers, redhorses)
* Centrarchidae (crappie, sunfishes)
* Clupeidae (gizzard shad, threadfin shad, unidentifiable clupeids, skipjack herring)
* Cyprinidae (common carp, minnows of genus Pimephales)
* Moronidae (temperate basses)
* Percidae (darters, yellow perch, walleye)
* Polyodontidae (paddlefish)
* Sciaenidae (freshwater drum) (Reference 2.4.2-3)
A total of 7814 fish eggs were collected at both locations. The families represented, in order of frequency, were:
* Sciaenid (freshwater drum) eggs (53.6 percent)
* Clupeid eggs (23.4 percent)
* Moronid eggs (14.3 percent)
* Unidentifiable eggs (8.7 percent)
* Percid eggs (less than 1 percent) (Reference 2.4.2-3)
A total of 3949 larval fish were collected, representing nine families. Larvae were more abundant downstream than upstream, mainly due to a high number of catostomid larvae downstream. The dominant larval taxon at both transects was the clupeids (67.4 percent). The other taxa contributing at least 1 percent of the total composition were:
* Catostomids (11.7 percent) 2.4.2-8                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* Moronids (10.2 percent)
* Centrarchids (5.6 percent)
* Atherinopsids (1.8 percent)
* Sciaenids/freshwater drum (1.3 percent)
* Cyprinids (1.3 percent) (Reference 2.4.2-3)
A single larval paddlefish was collected at the upstream location (CRM 18) during the survey.
The paddlefish is highly valued for its eggs, and the paddlefish fishery throughout the Tennessee Valley has been of special concern and is closely monitored and regulated. This larva is significant in that it indicates that at least some minimal spawning is occurring in the Clinch River arm of the Watts Bar Reservoir in the tailwater below Melton Hill Dam. (Reference 2.4.2-3)
Benthic Macroinvertebrate Community TVA assessed benthic macroinvertebrate communities of its reservoirs using the Reservoir Benthic Index (RBI) methodology. RBI is a metric used to assess relative conditions at selected locations within TVA reservoirs across the reservoir system. This index does not provide an absolute measure of aquatic community health as compared to an unimpounded river.
Therefore, an RBI score of "excellent" does not necessarily equate to an excellent benthic community, rather it indicates an excellent condition of the benthic community as compared to other, similar, reservoir-influenced sites within the TVA reservoir system. Because benthic macroinvertebrates are relatively immobile, negative effects on aquatic ecosystems can be detected earlier in benthic macroinvertebrate communities than in fish communities.
Accordingly, RBI data are used to supplement RFAI results to provide a more thorough characterization of aquatic communities. (Reference 2.4.2-6)
The RBI methodology was used in the 2011 aquatic habitat assessment of the CRN Site.
Benthic macroinvertebrate communities were sampled along transects with a Peterson or Ponar dredge downstream (CRM 15.0) and upstream (CRM 18.8) of the CRN Site during spring, summer, and autumn of 2011. RBI metrics were scored using evaluation criteria for lab-processed samples collected in the inflow reservoir zone. In addition to dredge sampling, during the autumn sampling event, shoreline benthic samples were collected with a kick-net and from rocks along the shoreline at both sites to obtain additional species richness and density data. (Reference 2.4.2-6)
Benthic community results were evaluated using seven metrics for assessing community characteristics. Results for each metric were assigned a rating of 1 (poor), 3 (good), or 5 (excellent), depending on how they scored based on reference conditions developed for Tennessee River reservoir inflow sample sites. The ratings for the seven metrics were then summed to produce a benthic score for each sample site. Potential benthic scores ranged from 2.4.2-9                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 7 to 35. Ecological health ratings were then assigned based on the scores using the following scale:
* 7 to 12 = Very Poor
* 13 to 18 = Poor
* 19 to 23 = Fair
* 24 to 29 = Good
* 30 to 35 = Excellent The individual metric ratings and overall RBI scores for the downstream and upstream locations based on the 2011 dredge samples are summarized in Table 2.4.2-4. (Reference 2.4.2-6) The individual metrics are summarized below:
* Average number of taxa (greater than 8.3 required for highest score): This metric is calculated by averaging the total number of taxa present in each sample at a site. Higher numbers of taxa (taxa richness) usually indicate better conditions than lower numbers of taxa. (Reference 2.4.2-6)
* Proportion of samples with long-lived organisms (greater than 0.8 required for highest score): This is a presence/absence metric that is assigned based on the proportion of samples collected at a given location containing at least one long-lived organism (e.g.,
Corbicula greater than 10 millimeters (mm), Hexagenia greater than 10 mm, mussels, snails). The presence of long-lived organisms is indicative of conditions that allow long-term survival. (Reference 2.4.2-6)
* Average number of Ephemeroptera, Plecoptera, and Trichoptera (EPT) Taxa (greater than 1.9 required for highest score): This metric is calculated by averaging the number of EPT taxa present in each sample at a site. Higher diversity (i.e., a higher average number) of EPT taxa indicates good water quality and better habitat conditions. (Reference 2.4.2-6)
* Percentage as oligochaetes (less than 12.0 percent required for highest score): This metric is calculated by averaging the percentage of oligochaetes in each sample at a site.
Oligochaetes are considered tolerant organisms, so a higher percentage indicates poor water quality. (Reference 2.4.2-6)
* Percentage as dominant taxa (less than 73.1 percent required for highest score): This metric is calculated by selecting the two most abundant taxa in a sample, summing the number of individuals in those two taxa, dividing that sum by the total number of individuals in the sample, and multiplying that number by 100 to obtain a percentage. The percentages for each of the 10 samples collected from each location are then averaged. Often, the most abundant taxa differ among the 10 samples at a site. This method for calculating the percentage allows more discretion to identify imbalances at a site than developing an average for a single dominant taxon for all samples at a location. This metric is used as an 2.4.2-10                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report evenness indicator. Dominance of one or two taxa indicates poor conditions. (Reference 2.4.2-6)
* Average density excluding chironomids and oligochaetes (density greater than 609.9 required for highest score): This metric is calculated using a two step process. First, the number of organisms in each sample excluding chironomids and oligochaetes is summed to obtain the density without chironomids and oligochaetes. Then an average of these densities for the 10 samples at a site is calculated. This metric examines the community by excluding taxa that often dominate under adverse conditions. A higher abundance of non-chironomids and non-oligochaetes indicates good water quality conditions. (Reference 2.4.2-6)
* Proportion of samples containing no organisms (no empty samples required for highest score): This metric is the proportion of samples at a site that have no organisms present.
Empty samples, or zero samples, indicate living conditions unsuitable to support aquatic life (e.g., due to toxicity or unsuitable substrate). (Reference 2.4.2-6)
The shorelines also were sampled for benthic invertebrates in autumn of 2011. Invertebrate samples were collected from submerged rocks at the upstream location. However, there was not sufficient rock substrate present at the downstream location to collect a sample. Therefore, a kick net was used to collect the sample from the downstream location. The differences in sampling techniques and habitat sampled limit direct comparisons of the results from these two locations. At the downstream location, chironomids and oligochaetes were the dominant taxa. At the upstream location, zebra mussels (Dreissena polymorpha), dipterans, hydrobiid snails, and oligochaetes were dominant. Mean densities (organisms/ square meter [m2]) were about 2 to 3 times higher at the upstream location than at the downstream location, but taxa richness values were similar downstream and upstream. (Reference 2.4.2-6)
Overall, the RBI scores calculated for samples collected from both the upstream and downstream locations during spring, summer, and autumn of 2011 were high. The ecological health rating for the downstream location was good in spring and autumn and excellent in summer. The ecological health rating for the upstream location was good in spring and excellent in summer and autumn. The downstream location received the lowest score (1) in only two metrics, the average number of EPT taxa in spring and the average percentage of oligochaetes in autumn. The upstream location received a score of 1 only in the average number of EPT taxa metric in spring. All other metrics were 3 or 5. Taxa richness was higher in samples from the upstream location than in samples from the downstream location during each of the seasons. Mean densities were higher in autumn than in spring or summer at both locations, due to high densities of zebra mussels. The most abundant species collected at either location in spring and summer was the snail Amnicola limosa. The Chironomidae family was particularly diverse, with more than 55 distinct species, and was the second most abundant taxon collected at either location during each of the seasons. In the shoreline samples, taxa richness was similar at the upstream and downstream locations. Very few taxa were present in shoreline samples that were not encountered in dredge samples. Overall, these data depict an 2.4.2-11                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report ecologically healthy benthic macroinvertebrate community in the reservoir both upstream and downstream of the CRN Site. The presence of high densities of zebra mussels upstream and downstream of the CRN Site is of concern because it indicates a potential for biofouling issues.
(Reference 2.4.2-6)
In addition to its 2011 RBI assessment of the benthic macroinvertebrate community and the aquatic habitat assessment at the CRN Site, TVA also conducted an evaluation in 2011 that focused on the freshwater mollusk community of the reservoir adjacent to the CRN Site. Both qualitative and semi-quantitative sampling methods were used to characterize the composition, density, and distribution of species within the mollusk community between CRM 15.0 and CRM 19.0. Bank-to-bank survey transects were spaced approximately 300 meters (m) apart and additional transects were placed about 50 m upstream and downstream of the anticipated locations of the discharge and intake structures near CRM 16.0 and CRM 17.9, respectively.
Thus, a total of 25 transects were sampled using semi-quantitative methods. In addition, qualitative sampling consisted of 1-hour (hr) timed searches at each of five sites: the discharge site, the intake site, and three sites in areas with the most suitable mollusk habitat, as determined based on data from the semi-quantitative sampling. The report documenting the details of the mollusk survey methods and results is provided in Appendix B of the TVA Technical Report: Clinch River Small Modular Reactor Site - Evaluation of Aquatic Habitats and Protected Aquatic Animals. (Reference 2.4.2-4)
The survey collected 74 live mussels from the following six species:
* Pimpleback (Quadrula pustulosa) (71.6 percent of the mussels collected)
* Fragile papershell (Leptodea fragilis) (17.6 percent of the mussels collected)
* Purple wartyback (Cyclonaias tuberculata) (less than 5 percent of the mussels collected)
* Pink heelsplitter (Potamilus alatus) (less than 5 percent of the mussels collected)
* Giant floater (Pyganodon grandis) (less than 5 percent of the mussels collected)
* Elephant ear (Elliptio crassidens) (less than 5 percent of the mussels collected) (Reference 2.4.2-4)
None of these species are federally listed as threatened or endangered. However, relic (nonliving) specimens of four mussel species federally listed as endangered were collected:
* Dromedary pearlymussel (Dromus dromas)
* Fanshell (Cyprogenia stegaria)
* Rabbitsfoot (Quadrula cylindrica)
* Spectaclecase (Cumberlandia monodonta)(Reference 2.4.2-4) 2.4.2-12                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report The presence of these relic specimens indicates that these species once resided in the Clinch River arm of the Watts Bar Reservoir near the CRN Site. Other relic mussel shells also were collected, including those of the following species:
* Black sandshell (Ligumia recta)
* Butterfly (Ellipsaria lineolata)
* Fluted kidneyshell (Ptychobranchus fasciolaris)
* Longsolid (Fusconaia subrotunda)
* Mucket (Actinonaias ligamentina)
* Ohio pigtoe (Pleurobema cordatum)
* Pocketbook (Lampsilis ovata)
* Pyramid pigtoe (Pleurobema rubrum)
* Round hickorynut (Obovaria subrotunda) (Reference 2.4.2-4)
The only snail species collected was the silty hornsnail (Pleurocera canaliculata), which is common within the Tennessee River basin (Reference 2.4.2-4).
Mean mussel density (semi-quantitative sampling) was 0.02 mussels/m2 and the mean catch rate (qualitative sampling) was 4.2 mussels per hour. The mussels did not appear to be distributed in a particular pattern, but they were most abundant upstream at transects 2 and 3 near CRM 19 and downstream around transect 21 at CRM 16. Substrates where mussels were encountered during the survey contained mixtures of cobble, gravel, and sand, but in numerous areas with this substrate type mussels were less abundant or absent. Unsuitable substrates included bedrock and heavily silted areas, which were located along the banks of the river.
(Reference 2.4.2-4)
The survey concluded that the mussel community at the CRN Site is in poor condition.
Evaluation of the 2011 mollusk and habitat survey in conjunction with historical surveys near the CRN Site indicated that habitat conditions to support mussels are generally inadequate, despite improvements in reservoir releases from Melton Hill Dam and Watts Bar Dam that began in 1991. In previous studies in the Clinch River arm of the Watts Bar Reservoir in the vicinity of the CRN Site, 16 mussel species were found in 1918, 10 species were found in 1982, 15 species were found in 1991, and six species were found in 1994. Comparing the 2011 mussel survey results to the 1982 survey results and accounting for sampling effort, the decline in numbers was estimated to be approximately 60 percent. In addition, no evidence of recent mussel reproduction was found in the 2011 survey, because no juvenile mussels were found and individuals 15 yr old or older were common.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Plankton Community The plankton component of the aquatic ecosystem is made up of drifting organisms, including algae (phytoplankton), protists, metazoans and larvae (zooplankton), and bacteria and archaea (bacterioplankton). These organisms form the bottom of the trophic food chain upon which the other levels depend. (Reference 2.4.2-9) During 2011, TVA surveyed both phytoplankton and zooplankton while characterizing the aquatic communities at the CRN Site. Plankton samples were collected at the same time as the water chemistry samples, monthly from March through December 2011. (Reference 2.4.2-6)
Phytoplankton For each sample, chlorophyll a concentrations were determined and a fraction of the algal community was identified and counted until the standard error for mean abundance was less than 10 percent. Basic statistics were calculated, including cell densities, biovolume, and mean abundance. Chlorophyll a concentrations were low in all samples, ranging from less than 1.0 to 5.0 micrograms per liter (&#xb5;g/L). In approximately 40 percent of the samples, concentrations were undetectable, and only two samples contained greater than 2 &#xb5;g/L. These low concentrations indicate that phytoplankton growth was very limited at the CRN Site. Turbulence causing light limitation was the most likely factor influencing growth. Occasional higher concentrations upstream were attributed to releases from the Melton Hill Reservoir, which is less turbulent. (Reference 2.4.2-6)
A total of 81 phytoplankton taxa were collected during the 2011 survey. The taxa collected were:
* Chlorophytes (32 taxa)
* Bacillariophytes (17 taxa)
* Cyanophytes (16 taxa)
* Chrysophytes (eight taxa)
* Euglenophytes (three taxa)
* Pyrrophytes (three taxa)
* Cryptophytes (two taxa)
The phytoplankton was numerically dominated by cyanophytes, which represented 90 to 99 percent of the samples at all locations and sampling times. The other algal groups consistently represented less than 2 percent of the assemblage each. Chrysophytes and cryptophytes represented approximately 1 percent of the assemblage, and euglenophytes and pyrrophytes were below 1 percent. (Reference 2.4.2-6)
Phytoplankton population size estimates ranged from 3600 to 52,000 cells per milliliter (cells/mL). Variability among locations and dates was accounted for by the abundance of 2.4.2-14                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report cyanophytes due to their overall dominance. Other algal groups showed the same trend.
Highest abundances were present at CRM 22, followed by CRM 15.5; lowest abundances were present at CRM 18.5. Higher abundance upstream may be due to releases from Melton Hill Reservoir. Abundance trended downward generally in the autumn, due to factors including seasonal declines in water temperature, light levels, and nutrients. (Reference 2.4.2-6)
Phytoplankton biovolume varied from 23,000 to 920,000 cubic micrometers per milliliter (m&#xb3;/mL), with a maximum in spring. The sample with maximum biovolume contained the diatom Melosira, which represented 60 percent of the total. This species is usually found in reservoirs rather than in flowing waters. Diatoms dominated biovolume in most months.
Although the cyanophytes dominated numerical abundance, they contributed an average of only approximately 7 percent of the total biovolume due to their small individual size. Euglenophytes and pyrrophytes often include large-celled phytoplankton. Therefore, a few individuals can contribute considerable biovolume. The pyrrophytes Glenodinium, Gymnodinium, and Peridinium contributed up to 65 percent of total biovolume when present. (Reference 2.4.2-6)
Phytoplankton populations in the area of the CRN Site were characterized by low abundance and appeared to result mainly from phytoplankton populations generated within Melton Hill Reservoir and transported downstream. Based on chlorophyll results, phytoplankton productivity in the sampled reach was very limited. Phytoplankton populations were essentially in a senescent phase. Productivity was likely light-limited due to turbulence within the water column.
(Reference 2.4.2-6)
Similar temporal patterns in the structure of the phytoplankton communities were evident among the sampling locations, though many phytoplankton taxa occurred at various times and locations. Quantitative characteristics (total and group cell densities) often varied substantially.
Overall, cyanophytes were dominant numerically throughout the 10-month study period, and bacillariophytes (diatoms) were typically dominant in terms of biovolume. Although no definitive spatial trends were evident, there was a general pattern of higher population densities at the most upstream site from March through August. These higher densities likely are related to entrainment of phytoplankton in releases from Melton Hill Dam and the proximity of the most upstream location to the dam. This pattern was not evident after August, when phytoplankton densities were substantially lower at all sampling locations due to increased flow and the interrelated effects of seasonal changes. (Reference 2.4.2-6)
Zooplankton Eighteen zooplankton taxa were collected during the 2011 survey. The most diverse group was the cladocerans (eight taxa), followed by the rotifers (seven taxa) and copepods (three taxa).
More copepod taxa may have been collected, but identification past the level of order was not possible. The three taxa identified were Diaptomus sp., Tropocyclops prasinus and Cyclops sp.
Overall taxa richness varied between four and eight taxa. Individual samples consisted of one to seven taxa. Only seven of the taxa were collected in all three sites in one sample period. Seven taxa were represented in only one sample. Bosmina longirostrus was the most common 2.4.2-15                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report species, present in 63 percent of the samples. Other common taxa were Daphnia lumholtzi and Asplanchna brightwellii. Cyclopoid copepods were present in 70 percent of the samples.
Calanoid copepods were in 43 percent of the samples. (Reference 2.4.2-6)
Zooplankton abundance was generally low, although variable, ranging from 34 to 12,790 individuals. Seasonally, densities rose through spring, peaked in July, then declined through December. Copepods were numerically dominant in April at all locations. Rotifers, including Asplanchna brightwellii and Conochilus unicornis, were dominant in May. Zooplankton density in May was highest at the farthest upstream location (CRM 22). All populations reached their highest levels in June. During this peak, the cladocerans were the dominant taxonomic group.
Common species included Daphnia lumholtzi, Daphnia pulicaria, Diaphanosoma leuchtenbergianum, Bosmina longirostris, and Chydorus sphaericus. Daphnia lumholtzi was the only taxon collected from the CRM 18.5 sampling location in June. Populations were low in abundance from August to December, generally with less than 500 organisms per cubic meter.
The lowest densities occurred in October and November, when samples contained high numbers of rotifers in the family Notommatidae. (Reference 2.4.2-6)
Biomass of the zooplankton community ranged from 1 to 42,300 micrograms dry weight per cubic meter. Most samples were characterized as low or sparse in biomass, with exceptions during peak densities in June and July. The clodocerans were the largest organisms and contributed the most to biomass estimates, followed by the copepods and rotifers. Biomass was highest in mid-summer and lowest in late autumn. The relative biomass of individual taxa was highly variable, in part due to succession within the assemblage, but also because of low abundance and diversity overall. (Reference 2.4.2-6)
Zooplankton assemblages in the vicinity of the CRN Site were characterized by low abundance and diversity throughout the 10-month sampling period. High turbulence and advection within the sampling reach likely limited zooplankton populations and affected their distribution.
Zooplankton assemblages often showed a notable degree of spatial heterogeneity in terms of both species composition and total abundance, but no systematic differences were evident.
Conversely, similar temporal patterns were evident among sites due to seasonal succession within the zooplankton communities and the proximity of the locations sampled. At each sampling location, copepods were the dominant taxonomic group in early spring (March and April). Rotifers were the dominant taxonomic group in May. Peak zooplankton abundance and biomass occurred during June and/or July and were dominated by Cladocera. These peaks were associated with warmer water temperatures and generally low flow. Abundance and biomass were extremely sparse throughout the remainder of the year, with no ecologically significant differences evident among sites. (Reference 2.4.2-6) 2.4.2.1.2    Melton Hill Reservoir Melton Hill Dam is operated primarily for the purposes of navigation and hydroelectricity generation. As discussed in Subsection 2.3.1.1.2.4, the main source of water for the Clinch River arm of the Watts Bar Reservoir at the CRN Site is the release from Melton Hill Dam.
2.4.2-16                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Releases from Melton Hill Dam range from no discharge to the maximum turbine capacity of about 21,000 cubic feet per second (cfs) to 23,000 cfs. Intervals of 12 to 22 hr with no releases are common. For the period 2004 through 2013, the overall average release was approximately 4670 cfs. Approximately 80 percent of the total annual inflow to Melton Hill Reservoir is discharged from Norris Dam. Because the water is discharged from deep within Norris Reservoir, water temperatures in the lower half of the water column of the Melton Hill forebay often remain cold (54 to 66&deg;F) from early spring until late autumn. (Reference 2.4.2-6) Melton Hill Reservoir exhibits a temperature gradient from north to south, which is influenced by the coal-fired Bull Run Fossil Plant that discharges warm water at approximately CRM 77. In January of 2000, surface water temperatures in Melton Hill Reservoir were 46.4&deg;F at CRM 65, 68&deg;F at CRM 77, 55.4&deg;F at CRM 44, and 46.4&deg;F at CRM 32. (Reference 2.4.2-10)
TVA monitors the ecological health of Melton Hill Reservoir at three locations: the forebay near the dam, the mid-reservoir, and the inflow at the upper end of the reservoir. TVA assesses the ecological health of the reservoir using measurements of DO, chlorophyll, fish and benthic macroinvertebrate communities, and sediment quality. Monitoring usually is performed on a 2-yr cycle, and the most recent ecological health ratings for Melton Hill Reservoir are based on monitoring in 2012. (Reference 2.4.2-11)
Physical and Chemical Characteristics Based on ecological health monitoring data for DO, the mid-reservoir has been rated good during every year of monitoring. DO typically also has been rated good in the forebay, except that it was rated fair in the forebay in 2000, 2001, and 2008 and poor in 2012 due to extended periods with low-flow conditions. (Reference 2.4.2-11) TVA valley-wide monitoring data from 2011 collected from the forebay (CRM 24.0) above Melton Hill Dam and the tailrace (CRM 23.1) below the dam indicated that DO in the forebay ranged from a depth-averaged concentration of 6.2 mg/L in June to 11.2 mg/L in March. DO concentrations in the tailrace ranged from 6.5 mg/L in June to 9.7 mg/L in May. (Reference 2.4.2-6)
In 2012 sediments at the forebay location were rated fair due to slightly elevated levels of arsenic. The mid-reservoir location was rated good because no PCBs or pesticides were detected and no metals concentrations were elevated in the sediment samples in 2012.
However, chlordane, PCBs, arsenic, and copper have been detected at elevated levels in sediment samples in some previous years. (Reference 2.4.2-11) Sediments collected in Melton Hill Reservoir in 2011 contained PCBs (Aroclor 1242). TDEC has issued fish consumption advisories for the reservoir due to PCBs and chlordane. (Reference 2.4.2-6)
Biological Communities TVAs reservoir monitoring program measures ecological health based on three biological indicators: chlorophyll, fish, and bottom life. Chlorophyll concentrations in Melton Hill Reservoir historically have been measured at the forebay and mid-reservoir locations. Ratings for 2012 were fair at the forebay and good at the mid-reservoir locations. Since 1998, chlorophyll 2.4.2-17                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report ratings at the forebay location have fluctuated between fair and poor. Ratings at mid-reservoir have varied through time with no clear trend. Reservoir flows play a role in the yearly fluctuations because lower flows allow more time for the algal community to expand. (Reference 2.4.2-11) In 2011, chlorophyll a concentrations at the forebay location ranged from 6 to 19 g/L and averaged 11.8 g/L (Reference 2.4.2-6).
The fish assemblage in 2012 was rated good at the forebay, fair at mid-reservoir, and poor at the inflow location. This was consistent with previous ratings, which reflected a fish assemblage at each location characterized by a lower abundance of fish and higher proportions of tolerant species than would be expected. In 2012, as in most previous years, higher diversity at the forebay and mid-reservoir resulted in higher ratings at those locations (Reference 2.4.2-11)
The benthic community was rated fair at the forebay and mid-reservoir and poor at the inflow in 2012. Most of the organisms collected were considered tolerant of poor conditions.
Historically, ratings were fair to poor at the forebay and poor at the inflow. Ratings have recently improved due to an increase in less tolerant species. (Reference 2.4.2-11) 2.4.2.1.3    Streams and Ponds on the CRN Site and the Barge/Traffic Area During several visits to the CRN Site and adjacent Grassy Creek Habitat Protection Area (HPA) in April and May 2011, October 2013, and October 2014, TVA mapped the locations of waterbodies within the survey area using a global positioning system (GPS). Also in 2014, TVA performed a survey of waterbodies in the Barge/Traffic Area between the CRN Site entrance and Tennessee State Highway (TN) 58. Surveys were conducted on the portions of the Barge/Traffic Area (101-ac) with the highest potential for disturbance that had not been previously surveyed. All streams documented in the surveyed areas, with the exception of the Clinch River arm of the Watts Bar Reservoir and associated backwaters, are first-order, unnamed tributaries of the reservoir. (Reference 2.4.2-4) Perennial streams have a well-defined channel, flowing water throughout the year under normal weather conditions, and support aquatic organisms. Intermittent streams have a well-defined channel, flowing water during wet seasons but not the entire year, and support aquatic organisms during periods when water is present. Intermittent streams flow in response to major rainfall events or as long as ground water is abundant. (Reference 2.4.2-12) The streams were determined to be perennial or intermittent based on the geomorphology of the channel, hydrologic characteristics, and the presence of visually observable aquatic fauna. Ephemeral streams/wet-weather conveyances (WWCs) flow diffusely over depressions, usually not in a well-defined channel, and only for short periods in response to major rainfall events. Flow in WWCs is not driven by ground water sources, and aquatic organisms are not present. (Reference 2.4.2-12)
Other than the Clinch River arm of the Watts Bar Reservoir and associated backwaters, TVA identified four perennial streams on the CRN Site and two perennial streams in the Barge/Traffic Area. One additional stream identified on the CRN Site and four additional streams in the Barge/Traffic Area were determined to be intermittent. Six ponds were identified on the CRN 2.4.2-18                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Site, all of which were determined to be man-made and four of which were originally created as stormwater retention ponds. Two ponds were identified in the Barge/Traffic Area. Descriptions of these streams and ponds are included in Table 2.4.2-5, and their locations are shown in Figure 2.4.1-2. (Reference 2.4.2-4)
Table 2.4.2-5 also includes the streamside management zone (SMZ) categories determined for the onsite streams and ponds. An SMZ consists of a stream and an adjacent management area of variable width where management practices are modified to protect water quality. They are intended to filter sediment and nutrients from overland runoff, allow water to soak into the ground, protect stream banks and lakeshores, provide shade for streams and improve the aesthetics of forestry operations. Perennial streams and intermittent streams with a well-defined channel and water flow 40 to 90 percent of the time require SMZs. The SMZs should be at least 50 feet (ft) wide, with increasing width depending on the percent slope of the adjacent land. WWCs do not require SMZs but would be protected by established Best Management Practices (BMPs) to the extent practical. (Reference 2.4.2-12) Based on the SMZ categories determined for the streams and ponds on the CRN Site, all but one are Category A and require a 50-ft SMZ, and one stream is Category B and requires a 100-ft SMZ. Stream S06 was designated as Category B to provide more protection to the spring from which it originates.
(Reference 2.4.2-4).
In addition to the perennial and intermittent streams on the CRN Site and the Barge/Traffic Area, the TVA survey identified the WWCs shown in Figure 2.4.1-2 (Reference 2.4.2-4). The WWCs on the CRN Site and the Barge/Traffic Area are listed in Table 2.4.2-5 and each is identified as natural or constructed.
A Hydrologic Determination Field Data Sheet, which is a form developed by the Tennessee Division of Water Pollution Control, was completed for each watercourse. The data sheets, which include scores for and descriptions of the onsite water bodies evaluated, are provided in Appendix A of the TVA report Clinch River Small Modular Reactor and Barge/Traffic Site - Evaluation of Aquatic Habitats and Protected Aquatic Animals Technical Report.
(Reference 2.4.2-4)
In March 2015, biological surveys were conducted on seven of the streams previously delineated on the CRN Site and the Barge/Traffic Area that were considered to have the greatest potential to support aquatic communities. Four of those streams are perennial and three are intermittent. An additional perennial stream located north of the CRN Site, Grassy Creek, also was sampled due to its proximity and habitat likely to support fish and crayfish. The streams were sampled using timed searches with a backpack electrofishing unit and a seine. All available habitat types were sampled in each stream (e.g., pool, riffle, run). On the CRN Site, the three streams sampled were perennial streams S01, S05, and S06 (Figure 2.4.1-2). The entire length of stream S01 (approximately 925 ft) was sampled, and no fish were collected. A few crayfish were observed but were too small for identification. In stream S05, one fish (a banded sculpin) and one crayfish were collected. No fish or crayfish were collected in stream S06. In the Barge/Traffic Area, one crayfish was identified in intermittent stream S09, and no 2.4.2-19                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report fish or crayfish were collected in the other three streams sampled (S07, S08, and S12) (Figure 2.4.1-2). Thus, only one fish was collected or observed in any of the streams on the CRN Site or the Barge/Traffic Area, and stable habitat supportive of a viable fish community was not observed in these streams. In Grassy Creek, 70 individuals of nine fish species were collected.
Of the aquatic species documented in any of the streams sampled, none were federally or state-listed. (Reference 2.4.2-13) 2.4.2.1.4      Aquatic Habitats in Offsite Transmission Line ROWs In addition to Watts Bar Reservoir and the streams and ponds on the CRN Site and Barge/Traffic Area, potentially affected aquatic habitats also could include offsite streams that intersect the 500-kV transmission line right-of-way (ROW) east of the CRN Site. Installation of a 69-kV underground transmission line is planned within the 5-mi segment of the existing ROW that extends east from the CRN Site to the Bethel Valley substation. Installation of the proposed underground transmission line potentially could affect aquatic organisms within streams crossed by the 69-kV line.
Three streams that cross the ROW are designated as aquatically sensitive areas (Figure 2.4.1-3). Ish Creek is an aquatic natural area that crosses the ROW approximately 0.5 mi from the CRN Site. Northwest Tributary is an aquatic reference area consisting of three small streams, two of which cross the ROW approximately 2 to 2.5 mi from the CRN Site. There are no recorded occurrences of federally or state-listed aquatic species within this ROW. The Tennessee dace, a fish designated by the state as in need of management, has been recorded in Ish Creek approximately 0.25 mi downstream of this ROW. Up to three additional streams also would be crossed: Streams S03 and/or S06 on the CRN Site near the northeastern boundary (Figure 2.4.1-2), and a small stream that crosses the ROW slightly southwest of the Bethel Valley substation.
As discussed in Subsections 2.2.3, 2.4.1.6, and 3.7.3.8, the transmission system structures within ROWs outside the CRN Site (other than the 69-kV underground line) would require modification by uprating, reconductoring, or rebuilding activities, but additional ROWs would not be developed. The lines that include segments or structures that may need to be modified are overlaid on a map of regional land cover types in Figure 2.2-7. Based on TVAs Natural Heritage database, the aquatic resources that potentially occur within the ROWs of the lines that may be modified are identified in Table 2.4.1-7. These resources include designated critical habitats for two endangered mussel species (one line segment to be uprated crosses over a riverine habitat unit for each species). Aquatic habitats within these existing ROWs would not be affected by these activities because of the limited potential for impacts associated with the types of activities to be performed and the use of BMPs to prevent or minimize erosion and sedimentation.
2.4.2-20                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.4.2.2 Important Aquatic Habitats U.S. Nuclear Regulatory Commission (NRC) guidance (NUREG 1555, Standard Review Plans for Environmental Reviews for Nuclear Power Plants: Environmental Standard Review Plan) identifies important aquatic habitats as follows:
* Wildlife sanctuaries, refuges, and preserves
* Habitats identified by the State Natural Heritage Program, the U. S. Fish and Wildlife Service (USFWS), or the National Marine Fisheries Service as unique, rare, or of priority for protection
* Wetlands, floodplains, or other resources protected by federal regulations or executive orders or by state regulations
* Critical habitats designated by the USFWS to protect listed species Wetlands are discussed in Subsection 2.4.1, Terrestrial Ecology, and floodplains are discussed in Section 2.3, Water.
A 2015 report by TVA assessed natural areas on, adjacent to, and within 3 mi of the CRN Site.
These areas are described in Subsection 2.4.1.3 and shown in Figure 2.4.1-3. Those that encompass notable aquatic habitats near the CRN Site include the Grassy Creek HPA, the eight aquatic natural areas and seven aquatic reference areas within the Oak Ridge Reservation (ORR), and the New Zion Unit Proposed State Natural Area (SNA). The Grassy Creek HPA adjoins the north end of the CRN Site and includes 265 acres (ac) intended to provide a buffer for sensitive habitat surrounding Grassy Creek and the Grassy Creek embayment of Watts Bar Reservoir. Within the ORR, the Ish Creek aquatic natural area (ANA1 on Figure 2.4.1-3) is located east of the CRN Site and within approximately 0.25 mi of the Site Boundary at its closest point. The New Zion Unit Proposed SNA is immediately east of the CRN Site and includes wetlands and the Raccoon Creek embayment of Watts Bar Reservoir.
(Reference 2.4.2-14; Reference 2.4.2-15) 2.4.2.3 Important Aquatic Species According to NUREG-1555, important species may include:
* Rare species, including:
Species federally listed as threatened or endangered Species that are proposed for federal listing Species that are candidates for federal listing Species that are state-listed as threatened, endangered, or a species of concern
* Commercially or recreationally valuable species 2.4.2-21                              Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* Species that are essential to the maintenance and survival of rare or commercially or recreationally valuable species
* Species that are critical to the structure and function of the local ecosystem
* Species that may serve as biological indicators to monitor the effects of the proposed facility on the environment
* Nuisance species that could cause problems for facility operations Aquatic species that are important with regard to the CRN Site are discussed below. In conjunction with agency coordination regarding listed species, TVA sent letters to the USFWS and TDEC in September 2016 requesting their concurrence with the listed species identified as important species for the site. These letters are included in Appendix A. Information provided in the consultation responses from USFWS and TDEC will be incorporated when received, and the responses will be included in Appendix A.
2.4.2.3.1    Federally Listed Species Species with federal listing status (currently listed, proposed for listing, or candidates for listing) and recorded occurrences in Roane County, Tennessee are identified in Table 2.4.2-6. There are 13 aquatic, federally-listed, threatened or endangered species and one candidate species with documented occurrences in Roane County, Tennessee. These include 12 freshwater mussels that are listed as endangered, one fish that is listed as threatened, and an aquatic cave salamander that is a candidate for listing. Eight of these federally endangered mussel species have Natural Heritage element occurrence rankings of historical (last recorded occurrence in the county greater than 25 yr old) or considered extirpated (no longer occurs in this portion of its former range). The species with only historical records of occurrence are:
* Spectaclecase
* Fanshell
* Fine-rayed pigtoe
* Alabama lampmussel
* Ring pink
* Orangefoot pimpleback
* Purple bean (Reference 2.4.2-4)
The turgid blossom pearlymussel is considered extirpated. Because these eight historical or extirpated species have not been detected in many decades, including the 2011 mollusk survey at the CRN Site, and habitat conditions in this area appear to remain unsuitable for mollusks, TVA has determined that these species either do not occur or occur at extremely low (undetectable) levels near the CRN Site. (Reference 2.4.2-4) Accordingly, these eight mussels 2.4.2-22                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report are not considered to have the potential to be affected by the CR SMR Project and are not addressed further.
The federally listed aquatic species potentially occurring in Roane County and ranked as extant (recorded occurrence less than or equal to 25 yr old) in the region are discussed below.
Although these species historically have occurred or potentially could occur in the vicinity of the CRN Site, recent surveys, including a survey performed by TVA in 2011, did not detect any aquatic federally listed species in the Clinch River arm of the Watts Bar Reservoir. (Reference 2.4.2-4)
Pink mucket (Lampsilis abrupta)
The pink mucket mussel was historically found in 25 river systems in the Tennessee, Cumberland, and Ohio River drainages, including the Clinch River. A recovery plan was prepared by the USFWS in 1985. At that time, the pink mucket was known to exist in 16 rivers throughout these drainages. Reasons for the decline of this species include impoundment, siltation, and pollution. The pink mucket is usually found in medium to large rivers greater than 20 m wide in moderate to fast flowing water. (Reference 2.4.2-16) However, individuals occasionally become established in small to medium sized tributaries of large rivers. The pink mucket inhabits rocky bottoms with swift current, usually in less than 3 ft of water. It appears to be tolerant of reservoir conditions with some flow. (Reference 2.4.2-4) The pink mucket has an elliptical shell approximately 105 mm long, 82 mm high, and 61 mm wide at full size. The surface of the shell is smooth except for the growth rings. Reproduction is similar to the other freshwater mussels. Females collect broadcast sperm and larvae (glochidia) temporarily attach to a fish host for dispersal. (Reference 2.4.2-16) The pink mucket spawns from August to September and releases larvae the following year between May and July. Fish hosts of the larval stage include largemouth bass, smallmouth bass, spotted bass, and walleye. (Reference 2.4.2-4)
The pink mucket mussel is federally listed as endangered and is listed by the State of Tennessee as endangered (Reference 2.4.2-4). The recovery plan for this species states that, as of 1985, individuals had recently been found downstream of the Melton Hill Dam (Reference 2.4.2-16). A live pink mucket was collected in 1984 slightly upstream of the CRN Site at CRM 19.1. However, the 2011 surveys of the Clinch River arm of the Watts Bar Reservoir adjacent to the CRN Site did not find any live or relic specimens of the pink mucket. (Reference 2.4.2-4)
Sheepnose (Plethobasus cyphyus)
The sheepnose is a medium-sized mussel, generally reaching less than 5 inches (in.) long. The shell is elongated and ovate with thick solid valves. The anterior is rounded and the posterior is bluntly pointed. The outer surface has a row of large, broad, tubercular swellings in the center.
The sheepnose is light yellow to yellowish brown in color with slightly darker growth arrest ridges. The interior of the shell is white, pinkish, or cream colored with iridescence at the posterior. The details of the life history of the sheepnose are unknown. The sheepnose is 2.4.2-23                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report thought to reach sexual maturity at a few years of age and spawns in early summer. The sheepnose is believed to be a short-term brooder that releases glochidia in masses. (Reference 2.4.2-17) The fish host has been identified as the sauger (Reference 2.4.2-4). Recent laboratory studies also have shown that successful metamorphosis can be obtained on fathead minnow (Pimephales promelas), creek chub (Semotilus atrromaculatus), central stoneroller (Campostoma anomalum), and brook stickleback (Culaea inconstans) (Reference 2.4.2-17).
The sheepnose mussel is federally listed as endangered, but is not listed by the State of Tennessee (Reference 2.4.2-4). The sheepnose is found in large streams in shallow shoals with moderate to swift currents. Substrates inhabited include sand, gravel, mud, cobble, and boulders. Historically, the sheepnose occurred in at least 76 streams and rivers in the Mississippi, Ohio, and Tennessee River basins across 14 states. The sheepnose is currently known to exist in 25 streams and rivers in the same 14 states, including the Clinch River.
Individuals have been recorded in the Clinch River as recently as 2006. (Reference 2.4.2-17) A living sheepnose was collected in 1994 at CRM 21.4 (Reference 2.4.2-4). Habitat destruction and degradation are the reasons for the decline of this species. No critical habitat has been designated for the sheepnose. (Reference 2.4.2-17) The 2011 surveys of the Clinch River arm of the Watts Bar Reservoir adjacent to the CRN Site did not find any live or relic specimens of the sheepnose (Reference 2.4.2-4).
Rough rabbitsfoot (Quadrula cylindrica strigillata)
The rough rabbitsfoot is a medium-sized mussel reaching up to 5 in. long (Reference 2.4.2-18).
The rough rabbitsfoot has a yellow to greenish shell covered in green rays and blotches. The interior of the shell is silvery to white and iridescent. The rough rabbitsfoot is found in a range of waterbodies, from small headwater streams to large rivers in moderate to swift current.
Substrates inhabited include silt, sand, gravel, and cobble. The rough rabbitsfoot spawns from May through June. (Reference 2.4.2-19) The rough rabbitsfoot is a short-term brooder, and the fish hosts for its glochidia include the whitetail shiner (Cyprinella galactura), spotfin shiner (C.
spiloptera), and bigeye chub (Hybopsis amblops) (Reference 2.4.2-18).
The rough rabbitsfoot is federally listed as endangered, and is listed by the State of Tennessee as endangered (Reference 2.4.2-20). The rough rabbitsfoot is endemic to the Tennessee River system and was historically found in the Clinch River above Norris Reservoir. The rough rabbitsfoot currently is found only in three streams and rivers in Tennessee and Virginia, including the Clinch River. Reasons for the decline of this species are habitat destruction and deterioration as a result of human activities. (Reference 2.4.2-19) Critical habitat has been designated for the rough rabbitsfoot in the Clinch River in Hancock County in Tennessee and Scott, Russell, and Tazewell Counties in Virginia (Reference 2.4.2-21). The 2011 surveys of the Clinch River arm of the Watts Bar Reservoir adjacent to the CRN Site did not find any live or relic specimens of the rough rabbitsfoot (Reference 2.4.2-4).

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Spotfin chub (Erimonax monachus)
The spotfin chub is a small fish reaching a maximum length of 92 mm. The spotfin chub is dusky green above the lateral line and silver on the lower sides, bordered by gold and green stripes.
There is no speckling on the body, but there is a distinct caudal fin spot. The sexes are dimorphic, with males having longer dorsal, anal, and pelvic fins. (Reference 2.4.2-22) The spotfin chub inhabits clear upland rivers in swift currents over boulder substrates. Spawning occurs from May through August (Reference 2.4.2-4).
The spotfin chub is federally listed as threatened, and is listed by the State of Tennessee as threatened (Reference 2.4.2-4). The spotfin chub existed historically in 24 streams in the upper and middle Tennessee River system. The spotfin chub is now found in only four rivers.
(Reference 2.4.2-23) The historical range included the Clinch River, and a single specimen was collected in 1893 in the area now occupied by the Norris Reservoir. Reasons for the decline of this species include habitat destruction by impoundment, channelization, pollution, turbidity or siltation, temperature changes, and possible over-collecting and interspecific competition.
Critical habitat has been designated for the spotfin chub in North Carolina and Virginia and in Cumberland, Fentress, and Morgan Counties in Tennessee. (Reference 2.4.2-22) The spotfin chub has been observed and collected in the City of Oak Ridge and could be present on the ORR (Reference 2.4.2-24). An individual was found in East Poplar Creek in 2002 during an ORNL stream sampling event (Reference 2.4.2-25). Although it has been recorded in Roane County, the spotfin chub is extremely unlikely to occur in the Clinch River arm of the Watts Bar Reservoir due to the unsuitable habitat conditions present in the reservoir (Reference 2.4.2-4).
Berry Cave salamander (Gyrinophilus gulolineatus)
The Berry Cave salamander is aquatic and an obligate cave dweller. The Berry Cave salamander reaches a maximum length of 136 mm and has a broad head with a truncated and spatulate snout and very small eyes. The gills are long and pink with purplish flecks. The tail is laterally compressed and has a fin that extends up the back. Adults typically are mottled dark brown, and juveniles are lighter in color. Unpigmented sensory pores are present on the head and along the sides of the body. (Reference 2.4.2-26) The Berry Cave salamander usually retains some larval characteristics as an adult, but it can metamorphose and lose these characteristics. Generally, cave salamanders become sexually mature without complete metamorphosis into the adult stage. Very little is known of its breeding habits or life span. The habitat of the Berry Cave salamander is subterranean waters in the Appalachian Valley and Ridge Province in East Tennessee. The Berry Cave salamander requires cave habitats with an inflow of organic detritus and aquatic prey. (Reference 2.4.2-27)
The Berry Cave salamander is a candidate for federal listing as endangered or threatened by the USFWS, and is listed by the State of Tennessee as threatened (Reference 2.4.2-20).
Ongoing threats to the species include lye leaching from quarrying activities, urban development, water quality degradation, and genetic hybridization with other salamander species (Reference 2.4.2-28). Water quality issues that threaten the species include pesticide 2.4.2-25                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report use, agricultural runoff, roadway runoff, and siltation due to forestry operations (Reference 2.4.2-27). The known locations of the Berry Cave salamander are in the Upper Tennessee River and Clinch River drainages. The Berry Cave population is in Roane County, Tennessee (Reference 2.4.2-28). Berry Cave is located approximately 9 mi south of the CRN Site and a few hundred yards west of Watts Bar Reservoir. None of the caves in which the Berry Cave salamander is known to occur are located on or adjacent to the CRN Site (Reference 2.4.2-26).
2.4.2.3.2  State-Listed Species Seventeen aquatic species with a state listing or other state protected status have recorded occurrences in Roane County (Table 2.4.2-6). These include two amphibians, five fish, nine mussels, and one plant that are state-listed as threatened or endangered, are deemed in need of management, or are of special concern. Eleven of these species also are federally listed. In Subsection 2.4.2.3.1, these federally listed species either were identified for evaluation or were eliminated from further evaluation because they are not considered to have the potential to be affected by the CR SMR Project due to their extirpation or historical absence from the area. The remaining aquatic species that have a state listing or other protective status include one amphibian, four fish, and one plant. None of these species were observed during biological surveys of aquatic habitats performed at the CRN Site in March 2015. These species are briefly discussed below.
Hellbender (Cryptobranchus alleganiensis)
The hellbender has been designated by TDEC as in need of management (Reference 2.4.2-20).
The hellbender is a completely aquatic, large salamander that can reach a length of up to 29 in.
The hellbender is brown to grayish in color with irregular dark blotches. The body is flattened horizontally, and the tail is flattened vertically. The hellbender has four short legs with four toes on the front feet and five toes on the rear feet. Along the body, between the front and hind legs, are skin folds that are used in respiration. Larval hellbenders have external gills, but at 18 months of age, a metamorphosis results in the loss of these gills. Hellbender breeding season occurs between September and early November. Males dig shallow depressions under a rock or log in which females deposit two long strings of eggs, which are fertilized by the male as they are laid. The males brood the eggs in the nest for 2 to 4 months. Hellbenders become sexually mature at 5 to 7 yr and can live up to 30 yr. Lack of suitable large objects has been proposed as a population-limiting factor for the hellbender. The hellbender usually is found in medium to large streams and rivers with fast-flowing water and rocky substrates. (Reference 2.4.2-29)
Hellbenders have been found in the tail waters below Melton Hill dam upstream of the CRN Site. The Clinch River arm of the Watts Bar Reservoir potentially provides habitat suitable for the hellbender, including large rocks and logs for breeding sites, but the hellbender has not been documented near the CRN Site. (Reference 2.4.2-30) The last known record of the hellbender in the Clinch River arm of the Watts Bar Reservoir was a collection in the Melton Hill dam tailwaters in 1989. This species has not been reported from the Clinch River since then and is assumed to no longer be present. (Reference 2.4.2-31) 2.4.2-26                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report Blue sucker (Cycleptus elongatus)
The blue sucker is listed as threatened by TDEC (Reference 2.4.2-4). The blue sucker is a fish which is olive-blue or slate-olive on its back and sides with a lighter bluish-white ventral coloring.
Its lips are white and its fins are dark blue-gray to black. The blue sucker reaches a maximum of 825 mm in length. Spawning occurs in April through May in deep riffles with substrates of cobble and bedrock. The blue sucker reaches sexual maturity at ages 3 through 5 yr and can live up to 22 yr. (Reference 2.4.2-32) The blue sucker is found in deep pools of large, free-flowing rivers with swift currents (Reference 2.4.2-4). Characteristic habitats have very swift flow and cobble or bedrock substrates. Juveniles are found in shallower and less turbulent areas. (Reference 2.4.2-32) Blue sucker populations have declined drastically due to the effects on large rivers from impoundments and increased siltation (Reference 2.4.2-4). The blue sucker is extremely unlikely to occur in the Clinch River arm of the Watts Bar Reservoir due to the unsuitable habitat conditions present in the reservoir.
Flame chub (Hemitremia flammea)
The flame chub has been designated by TDEC as in need of management (Reference 2.4.2-4).
The flame chub is a small minnow that reaches a maximum length of approximately 3 in. The flame chub has a distinct caudal spot and a dark lateral stripe bordered above by a pale gold area. Sexually active males are bright scarlet to orange ventrally and retain some of this coloring throughout the year. Spawning occurs from late January to June. The flame chub can live for up to 2 yr. Spawning has been reported in flooded agricultural fields and pastures. The flame chub inhabits springs, spring-fed streams, and shallow seepage waters in locations where gravel and aquatic vegetation are present. (Reference 2.4.2-33) Populations have declined with the continued alteration of spring habitats (Reference 2.4.2-4). The flame chub is unlikely to occur and was not found in surveys of streams on the CRN Site or Barge/Traffic Area, which lack suitable habitat conditions.
Tangerine darter (Percina aurantiaca)
The tangerine darter has been designated by TDEC as in need of management (Reference 2.4.2-4). The tangerine darter is a fish that reaches a maximum length of 7 in. Males have an orangish red to tangerine color on the lower sides and ventral area, while females are yellow in this area. A black stripe extends from head to tail, and small black dots above this stripe are unique to the species. Male dorsal fins are dusky orange and female dorsal fins are yellow.
Males reach sexual maturity after 1 yr and females reach sexual maturity after 2 yr. Spawning occurs in May through July in gravel-bottomed riffles. Eggs and sperm are released onto the gravel bed with no brooding or nesting. (Reference 2.4.2-34) The tangerine darter inhabits clearer reaches of moderate to large headwater tributaries of the upper Tennessee River drainage and is most abundant in smaller tributaries. Preferred habitats most of the year are deeper riffles and runs with substrates of bedrock, boulders, and large rubble, but in winter, deeper pools are used. (Reference 2.4.2-4) The tangerine darter potentially could occur in some 2.4.2-27                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report sections of Grassy Creek. It is unlikely to occur and was not found in surveys of streams on the CRN Site or Barge/Traffic Area due to the unsuitable habitat conditions.
Tennessee dace (Chrosomus tennesseensis)
The Tennessee dace has been designated by TDEC as in need of management (Reference 2.4.2-4). The Tennessee dace is a small minnow reaching a maximum length of approximately 2 in. The Tennessee dace is found in pools in spring-fed headwaters and small creeks, typically 1 to 2 m wide with substrates of gravel, sand, and silt (Reference 2.4.2-35). The Tennessee dace typically inhabits shallow pools in association with undercut banks and debris in small, low-gradient, woodland tributaries of the upper Tennessee River drainage. The Tennessee dace spawns from April through July. (Reference 2.4.2-4) The Tennessee dace has been observed on the ORR and potentially could occur in some sections of Grassy Creek (Reference 2.4.2-24).
It is unlikely to occur and was not found in surveys of streams on the CRN Site or Barge/Traffic Area due to the unsuitable habitat conditions.
Nutalls waterweed (Elodea nutallii)
Nuttalls waterweed has been designated by TDEC as a species of special concern (Reference 2.4.2-20). Nuttalls waterweed is a submerged, aquatic, perennial plant with stems growing up to 40 in. long. The stems are branched, and the white flowers float on top of the water. Male and female flowers grow on separate plants. (Reference 2.4.2-36) Nuttalls waterweed reproduces sexually with seeds during June, July, and August. The male flowers break off the plant and split open, spreading the pollen on the waters surface. Pollination occurs when the pollen comes in contact with a female flower. Nuttalls waterweed also can reproduce vegetatively by fragmentation of the stem, which is the most common method. (Reference 2.4.2-37) The leaves are linear to lance-like, bright green, and do not have stalks. The edges are folded, and there are two to three leaves per whorl. Nuttalls waterweed generally is found in still water growing in fine sediment. (Reference 2.4.2-36) Nuttalls waterweed prefers quiet waters of lakes or streams and typically is found in calcareous (hard) water (Reference 2.4.2-37).
2.4.2.3.3    Species of Commercial or Recreational Value TVA and state fisheries agencies developed a Sport Fishing Index that was used until 2008 to provide an indication of the quality of sport fishing for individual species in TVA reservoirs (Reference 2.4.2-38). Sportfish surveys were performed in the spring, but not every reservoir was sampled each year (Reference 2.4.2-39). TVA discontinued the spring sport fish survey after 2014 (Reference 2.4.2-40). The Sport Fishing Index scores for each reservoir and species were based on population measures (the number of fish and the size and health of individual fish) and information about angler use of the reservoir and their success (the number of anglers fishing for a particular type of fish and the number of that type that they actually catch). The Sport Fishing Index score for a given species could range from 60 (excellent) to 20 (very poor).(Reference 2.4.2-38) For Watts Bar Reservoir, the most recent sport fish survey statistics available are from 2014, but the most recently calculated Sport Fishing Index score available is 2.4.2-28                                  Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report from 2008. The 2008 Sport Fishing Index scores for Watts Bar Reservoir indicate that scores for black basses, smallmouth bass, striped bass, white bass, crappie, white crappie, and channel catfish were below the 2008 average across the TVA region and the scores for black crappie, largemouth bass, and spotted bass were above the average. (Reference 2.4.2-39; Reference 2.4.2-38; Reference 2.4.2-41)
To characterize the fish community in the Clinch River arm of the Watts Bar Reservoir, TVA selected two fish sampling locations, one upstream and one downstream of the CRN Site.
Sampling by electrofishing and gill netting was conducted in February, May, July, and October of 2011 to document seasonal variation in fish community composition. An average of 14 commercially valuable and 22 recreationally valuable fish species were collected at the downstream location during 2011 and an average of 15 commercially valuable and 24 recreationally valuable species were collected at the upstream location. The commercially and recreationally valuable fish species collected are identified in Table 2.4.2-1. Commercially valuable species are defined as those that can be legally harvested by commercial fishing methods for sale as meat, roe, or bait. Recreationally valuable species are those species that are commonly sought by anglers or bowfishers or are used for bait. (Reference 2.4.2-6) As discussed in Subsection 2.4.2.1.1, fish consumption advisories have been posted by TDEC on Watts Bar Reservoir in the vicinity of the CRN Site warning that, due to the levels of contaminants (PCBs) in their tissues, consumption of catfish and sauger should be limited to about two meals per month and striped bass should not be eaten (Reference 2.4.2-42).
For Melton Hill Reservoir, the 2008 Sport Fishing Index scores for black basses, largemouth bass, smallmouth bass, spotted bass, crappie, black crappie, white crappie, and sauger were below the 2008 average across the TVA region, while the scores for channel catfish and striped bass were above the average (Reference 2.4.2-39). Melton Hill Reservoir is popular for sportfishing for species that include muskellunge, striped bass, hybrid striped bass, white crappie, largemouth bass, and skipjack herring. In 2008, there was an advisory against the consumption of catfish from the reservoir due to PCB levels. Muskellunge are stocked annually in Melton Hill Reservoir by the Tennessee Wildlife Resources Agency. (Reference 2.4.2-43) 2.4.2.3.4  Nuisance Species Aquatic invasive species are non-native species that are likely to cause economic and/or environmental harm. Other terms for these types of species are nuisance, alien, non-indigenous, exotic, or undesirable species. (Reference 2.4.2-44) Within the Tennessee Valley, TVA has identified seven invasive species that constitute the greatest threat to rare native species or the balance of the aquatic community in general. These seven species are:
* Common carp (Cyprinus carpio)
* Grass carp (Ctenopharyndogon idella)
* Alewife (Alosa pseudoharengus)
* Blueback herring (Alosa aestivalis) 2.4.2-29                                Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report
* Rusty crayfish (Orconectes rusticus)
* Asiatic clam
* Zebra mussel (Reference 2.4.2-45)
The Kentucky River crayfish (Orconectes juvenilis) is an invasive, non-native species that is very similar to the rusty crayfish, and until recently Orconectes juvenilis was considered to be the same species as Orconectes rusticus (Reference 2.4.2-46). The Asiatic clam and zebra mussel were found in the 2011 sampling by TVA in the Clinch River arm of the Watts Bar Reservoir (Reference 2.4.2-6). The Asiatic clam and zebra mussel potentially are the most problematic of these nuisance species because they contribute to biofouling of water intake systems (Reference 2.4.2-44). TVA has a monitoring and eradication program for these species at generating facilities, including the use of chemical and heated-water treatments. Nuisance species can cause other problems as well, including negative effects on fishing and musseling, and they can contribute to the decline of native species through competition or predation (Reference 2.4.2-44).
Federal regulations regarding invasive species include Executive Order 13112 - Invasive Species, which requires federal agencies to:
* Prevent the introduction of invasive species
* Detect and respond rapidly to control populations of such species in a cost-effective and environmentally sound manner
* Monitor invasive species populations accurately and reliably
* Provide for restoration of native species and habitat conditions in ecosystems that have been invaded The nuisance species that occur in the vicinity and have the greatest potential to affect the CR SMR Project, the Asiatic clam and zebra mussel, are briefly described below.
Asiatic Clam (Corbicula fluminea)
The Asiatic clam is a small, filter-feeding bivalve with a maximum size of 1.5 in. The outer surface is light yellow to dark brown or black and the interior is white to light purple. The Asiatic clam is hermaphroditic and capable of self-fertilization and does not require a host fish for successful development. Larvae are brooded in the gills, and individuals can release up to 70,000 juveniles per yr. The Asiatic clam is native to China, Korea, and southeast Russia. The Asiatic clam was first collected in Washington State in 1938. The Asiatic clam is currently distributed across 38 states and the District of Columbia, including almost every river and reservoir in Tennessee. It is hypothesized that the Asiatic clam entered the country as a food item used by Chinese immigrants. Currently, the Asiatic clam is spread by human activities such as accidental bait bucket introductions and aquaculture species, and intentional introductions by people that eat them. The Asiatic clam causes environmental harm by competing for habitat and 2.4.2-30                                    Revision 1
 
Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report food with native bivalves. The Asiatic clam causes economic harm by biofouling water intakes of power plants and industrial and municipal water supplies. (Reference 2.4.2-44)
Zebra Mussel (Dreissena polymorpha)
The zebra mussel is a small mussel reaching a maximum size of 1.5 in. The outer shell can be cream colored without banding but is usually striped with parallel brown or black bands. The inside surface is bluish white. The zebra mussel attaches to hard surfaces using byssal threads.
The zebra mussel spawns in spring or summer at water temperatures of 14 to 16&#xba;C (57 to 60&#xba;F). The zebra mussel is a broadcast spawner, with the eggs fertilized in the water column.
Larvae hatch within 3 to 5 days and do not require a fish host for successful development. The zebra mussel is native to the Black, Caspian, and Azov Seas and was first discovered in the United States in Lake St. Claire in 1988. The zebra mussel is thought to have arrived in the ballast of a commercial cargo ship and later spread by passive drifting of the larvae and adults attachment to boats and other water gear. By 1990 the zebra mussel was found in all of the Great Lakes, and by 1991 the zebra mussel had invaded the Illinois and Hudson Rivers. In 1994 the zebra mussel was reported in 19 states, and by 2002 the zebra mussel had invaded 23 states. (Reference 2.4.2-44)
The zebra mussel causes harm by biofouling intake pipes of power plants and industrial and municipal water supplies. Biofouling by the zebra mussel can be so intense that is has sunk navigational buoys and deteriorated dock pilings. The zebra mussel also competes with native bivalves for habitat and food. After its arrival in the Great Lakes, the biomass of plankton was significantly reduced. Zebra mussels also settle on native mussel species, which can cause death by interfering with normal valve operation, causing shell deformity, smothering siphons, competing for food, impairing movement, and depositing metabolic waste into underlying mussels. (Reference 2.4.2-44) During the mollusk survey by TVA at the CRN Site in 2011, biologists noted an abundance of zebra mussels throughout that reach of the reservoir. Only three of the other mussel species found were not infested with zebra mussels. Zebra mussels were particularly abundant in areas with solid and stable substrates, and were especially dense on bedrock. (Reference 2.4.2-47) 2.4.2.4 References Reference 2.4.2-1.
