Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3.2-1 Revision 1 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 The return flow was estimated to be 11,480 mgd, which represents 96.1 percent of the water withdrawn.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Of the 11,747 mgd of surface water withdrawn from the Tennessee River system in 2010, thermoelectric power withdrawals were an estimated 10,046 mgd; industrial withdrawals were 1116 mgd; public supply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.

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3.2-2 Revision 1 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

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3.2-3 Revision 1 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 2.3.2-4 Revision 1 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

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3.2-5 Revision 1 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

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3.2-6 Revision 1 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)

Clinch River Nuclear Site Early Site Permit Application Part 3, Environmental Report 2.3.2-7 Revision 1 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.
