RESPONSE TO FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL The following provides TVA's responses to F&WS' six RAIs:

F&WS Question No.1:

We request more information regarding when and by whom aquatic/terrestrial survey efforts were conducted along the 160 miles of transmission line rights-of-way.

We would also like to see results of some of these surveys.

If surveys are incomplete, we would like a commitment to complete the aquatic and/or terrestrial surveys prior to any new construction or maintenance activity that may affect listed species known in the respective county or counties.

TVA RESPONSE:

TVA's Heritage staff in Knoxville regularly receives requests t:o review right-of-way (ROW) areas scheduled for vegetation management or other maintenance or modification activities.

There are approximately 19,000 ROW miles in the TVA system and requests are received involving approximately one-third of these miles every year.

Such a large workload means that it is not possible to field-survey miles.

Instead, TVA utilizes the best tools available such as Heritage staffers who "fly" the transmission line corridors (using video available to them on TVA InsideNet computer files) to "see" the kinds of habitats present in the project area.

They then overlay the ROW with records o:f sensitive plants and animals from the Heritage data base and consider the likelihood of any listed plant or animal to inhabit the section of line involved in the project.

The standard criteria and guidelines developed years ago are then applied to make conservative vegetation and/or land management recommendations to the Power System Operations project managers.

In general, the listed species are assumed to be present, and the recommendations are conservatively made with the objective of protecting the species.

Vegetation management recommendations can involve hand-clearing requirements, restrictions on use of herbicide sprays, bush hogging, etc.

If there is ground-distu.rbing work to be done (e.g., pole replacement, lightning arrester installation, etc.), and the video fly-overs indicate likely habitat for a listed plant or animal, field visits are made to those project areas to check for the presence of listed species.

RESPONSE ro FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL The criteria and guidelines used by TVA's Heritage staff for protection of listed species potentially affected by power line work activities were shared with the F&WS when they were first developed, and again in a February 2005 demonstration session Eor visiting F&WS personnel.

In both reviews, F&WS personnel concurred that these were reasonable methods to perform this work. If there is further interest by other F&WS personnel in reviewing this process, the Heritage staff would be pleased to sched.ule another session. contains a list of biologists, both TVA personnel and contractors that work directly on transmission line projects (such as re-clearing or pole replacement) that involve consideration of potential impacts on threatened and endangered species, wetlands, or natural areas.

Included are staff personnel that do the desk-top reviews and/or field reviews, if necessary.

Included with this list are three examples presented wherein actual field work was required because the database flagged potentially impacted species.

F&WS Question No.2:

Prov;:de river bottom dissolved oxygen data for both winter and summer months under low and high flow conditions at and below BFN's diffuser pipes within the mixing zone and at the mixing zone edge, and describe any changes anticipated with the addition of Unlit 1.

TVA RESPONSE: (Wheeler Profiles 1990-2005 Revl.xls) contains profiles collected from Wheeler Reservoir at Tennessee River Mile (TRM:

locations 277.0 (Wheeler Dam Forebay) and 295.9 (Transition zone -2 miles upstream of BFN).

Beginning in 1990, the sampling was conducted annually, but it was changed to every other year in 1995 to about 1998, and now it is back to annual monitoring due to the drought conditions of recent past years and the implementation of the River Operations study.

The sampling was usually done once a month from April through September as part of the Vital Signs Monitoring program which targets the phytDplankton productive months and coincides with natural dissolved oxygen (DO) variability due to warming water temperatures and potential thermal stratification.

The profiles are collected with a Hydrolab profile at the deepest part of the main channel at the given river mile.

In general, data is taken starting at the reservoir bottom, followed by taking measurements

RESPONSE TO FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL about every two meters to the surface.

At TRM 295.9, the only DO recorded at <5mg/L (approximately 4.8 mg/L) was in the lower 3 meters of the water column in June 2001.

Overall, DO conditions for the years monitored appear to be very good at this location.

Attachments 4 and 5 show special Hydrolab profiles for BFN collected on August 31, 2005, and September 14, 2005, at three locations: Below (i.e., downstream of) the BFN mixing zone at TRM 293.3, approximately 250 to 300-feet downstream from the river water temperature monitoring station; in the mixing zone at TRY.'

293.9, approximately 250 to 300-feet downstream from the diffusers; and at TRM 295.9, the normal transition zone monitoring location for Wheeler Reservoir, which is upstream from the m'.xing zone.

On August 31, 2005, and September 14, 2005, Units 2 and 3 were operating at full power with no cooling towers in operation.

These data further support the above conclusion that DO is very unlikely to be an issue in the river reach near BFN.

In addition to not having any significant impact on the measured DO levels in, and downstream of, the mixing zone, the warmer water exiting the BFN diffusers is buoyant and rises to the surface rather than moving along the bottom of the reservoir, so its impact on benthic species is also minimal.

Some historical data are also available from monitoring conducted after Browns Ferry Unit 1 achieved initial criticality on August 17, 1973.

Unit 1 began initial operation on October 15, 1973, and Units 2 and 3 began initial operation on August 28, 1974, and September 12, 1976, respectively.

DO data are contained in reports of Water Quality and Biological Conditions in Wheeler Reservoir during operation of BFN from August 17, 1973, through December 31, 1980.

During the period of operation covered by these reports, it was concluded that there was no apparent long-term alteration of water quality in Wheeler Reservoir due to the operation of BFN.

This conclusion was based on statistical comparison of the quarterly means of water quality parameters from upstream and downstream stations, including DO.

Additional information regarding the anticipated impact of Unit: 1 on DO is found in Section 4.3.6.3 of the Final Supplemental Environmental Impact Statement (FSEIS) for Operating License Renewal of the Browns Ferry Nuclear Plant in Athens Alabama, 2002, which describes the results of computer simulations using a two-dimensional water-quality model of Wheeler Reservoir.

In general, the model predicts that the startup of Unit 1 will not:

have an adverse impact on DO.

In fact, the model predicts that:

in areas downstream of the plant, the minimum level of DO will increase.

This is primarily due to higher levels of

ENCLOSURE BROWNS FERRY NUCLEAR PLANT (BFN) UNITS 1, 2 AND 3 -

RESPONSE TO FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL photosynthesis, induced by warmer water temperatures, created by the addition of heat from Unit 1. For example, at TRM 292.0, about: 2 miles downstream of the diffusers, the model predicts that for a hot, dry year such as 1988, the minimum daily DO will increase by about 0.8 mg/L after the startup of Unit 1.

Other processes influencing DO are related to mixing induced by the plant diffusers.

Bottom diffusers usually help to increase DO ill bottom layers of the reservoir immediately downstream of the plant.

This is due to upwelling of the river water as it flows up and over the diffuser pipes, and due to turbulence created by the jets from the diffuser ports.

These processes mix oxygen-rich water in the surface region of the reservoir with water of lower DO in the bottom of the reservoir.

These phenomena have been documented in studies performed for the TVA Sequoyah Nuclear Plant, located on the Tennessee River in the Chickamauga Reservoir (TVA, 1990).

The startup of Unit 1 will increase reservoir mixing by the action of the diffuser jets.

Any changes in DO created by these processes, however, will likely be small compared to the action of photosynthesis, as discussed above.

RESPONSE To FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL F&WS Question No. 3:

Provide modeling data depicting the thermal plume within Wheeler Reservoir when all 3 nuclear plants are operating at full capacity (120% of their originally licensed power production capacity).

Describe any differences expected in the extent of effects on bottom and top waters before and after startup of Unit 1.

TVA RESPONSE: contains a copy of a Power Point presentation showing the results of a three-dimensional simulation of the diffuser thermal effluent with all three units operating at extended power uprate (120 percent of originally licensed thermal power).

The presentation is the same as that shown to F&WS in the meeting of October 27, 2005.

The river flow is 10,000 cubic feet per second, the minimum daily average flow at BFN for the summer heating season, as targeted by TVA River Operations.

The upstream ambient river temperature is 870F, the approximate maximum temperature allowing sustained operation of BFN at full power without exceeding the maximum river temperature downstream of the plant specified in the NPDES permit.

At higher ambient temperatures the plant would have to initiate a derate to protect the NPDES limit.

The results of the three-dimensional simulation represent the worst case scenario for conditions including all three BFN units operating at max generation with extended power uprate.

Compared to the operation of Unit 2 and Unit 3, the startup of Unit 1 will increase the volume of waste heat in Wheeler Reservoir.

Thus, with Unit 1, the spatial extent of the thermal discharge will be larger, both at the bottom and at the surface of the reservoir.

However, the magnitude of the temperature extremes along the downstream boundary of the mixing zone will not change significantly, because of the plant requirements to maintain compliance with the NPDES river temperature limits.

RESPONSE TO FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL F&WS Question No.4:

Provide some discussion on the thermal plume produced by BFN and whether the thermal plume will/will not affect the host fish for listed mussel species within Wheeler Reservoir.

TVA RESPONSE:

Host Fish Impacts on Glochidia (mussel larvae)

The four threatened and endangered freshwater mussels (pink mucket, rough pigtoe, orangefoot pimpleback and fanshell) found in Wheeler Reservoir are all primarily located in the riverine sect:.on below Guntersville Dam (Figure 1).

Known fish hosts for the pink mucket and rough pigtoe are all common reservoir species and are primarily sportfish except for freshwater drum and rosefin shiner (TVA 2005a) (Table 1).

The orangefoot pimpleback and :anshell fish hosts are logperch, darters, and sculpins (IVA 2005a).

Mettee (1996) reported no records of mottled sculpin, tangerine darters, or blotchside logperch in the highland rim region of Alabama.

Rosefin shiners, greenside darters, and banded sculpins are found in tributary streams to Wheeler Rese:voir; snubnose and banded darters are only found in the headwaters of the Elk River.

All of the reservoir fish species, acting or serving as mussel.

hosts, have the ability to detect temperature increases and avoid the river channel affected by BFN's diffusers.

The thermal model illustrates that the left descending bank opposite of BFN is riot affected by the thermal plume and provides passage for migrating host species.

Baxter and Buchanan (1998) tracked sauger with radio telemetry and found that sauger did not have a channel location preference in the vicinity of BFN, and migration was not affected by the thermal plume.

BFN's thermal variance of 90 E'

(32.2 C) does not exceed most of the fish host species upper lethal temperature limits.

The fanshell and orangefoot pimpleback have not been reported since 1978 and are considered very rare.

The fish host species found in the Wheeler Reservoir are tolerant of high ambient r:.ver temperatures.

RESPONSE TO FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL Impa:ts On Reproductive Rates Via Impacts To Host Fish And Temperature Mortality Data For Larval Fishes, Not Just Adult Fish Mortality Two species of special interest, sauger and yellow perch, were the focus of TVA's BFN thermal variance studies because both are considered coolwater species and are theoretically more susceptible to elevated water temperature.

Based on results of the studies conducted from 1985 through 1992 (Baxter and Buchanan 1998), operation of BFN had no significant adverse impact on the reproductive success of either species, or the annual spawning migration of sauger past BFN.

However, Maceina et al. (1998) found that sauger-spawning success was adversely impacted by over fish.ng and drought conditions (e.g., low flows and decreased turb.dity) in the Tennessee Valley during 1985 through 1988.

TVA 2002, Chapter 4 Section 4.4.10.4, pages 4-46 through 4-48 stated that the flow studies conducted by TVA at BFN have indicated that the majority of water entrained originates from the right side of the main river channel.

This pelagic area contains significantly lower densities of drifting fish larvae than found in the overbank areas (Figure 4.3.10-1).

Higher dens:ities of fish eggs (primarily freshwater drum eggs) are transported in the channel portion of the river, but entrainment of drum eggs (and larvae) has not resulted in noticeable decreased abundance of this species; nor is it expected to, under the increased condenser cooling water flow rates.

The thermal plume model illustrates that the plume rises rapidly towards the surface mixing with the ambient water.

Very little bottom channel area is exposed to high temperatures.

Larval sauger and eggs drifting past BFN would have very limited exposure to high temperatures due to their demersal nature of drifting close to the bottom.

During the spring when saugers spawn, ambient temperatures would be much cooler compared to the worst: case scenario temperature model.

Based on the information, TVA concludes that BFN does not adversely affect migration, reproductive rates, larval, juvenile, or adult fish host species in Wheeler Reservoir.

RESPONSE TO FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL Biological (Vital Signs) Monitoring After 3 Units Are Operating At EPU TVA 2002, Chapter 4, Section 4.4.10.4, page 4-47, last paragraph, stated that TVA will confirm the expected levels of impingement and entrainment by monitoring under current 2-unit operation and following the return of Unit 1 to service.

TVA's vital signs monitoring program will also continue to assess aquatic ecological communities in Wheeler Reservoir. Although not expected, if based on these monitoring studies it is determined that increased impingement and entrainment are resulting in unacceptable environmental impacts, TVA would assess the technologies, operational measures, and restoration measures that could be undertaken to remedy this and institute appropriate measures in consultation with appropriate federal and Alabama agencies.

All entrainment and impingement monitoring is conducted with the same procedures used during the pre-operational monitoring for BFN.

F&WS Question No. 5:

For future in-stream work involving any construction likely to affect listed aquatic species or streams with suitable habitat:

for listed aquatic species (but no survey data), indicate whether TVA is willing to conference and possibly consult on their effects determinations and conduct needed surveys prior to effects determinations.

TVA RESPONSE:

During the planning of all transmission line construction activities, including new construction and subsequent maintenance operations, TVA attempts to avoid in-stream work.

If in-stream work appears unavoidable, TVA assesses the potential for effects on listed species.

If there is inadequate existing information to conduct this assessment, TVA will conduct surveys in the project area.

If the result of TVA's assessment is the determination that the proposed in-stream work may affect listed species, TVA will consult with the U.S. F&WS.

In the past, the need for such consultation has been very rare and TVA does not anticipate it occurring often in the future.

The following briefly summarizes the environmental compliance review process TVA Heritage Resources use for maintenance and modifications of transmission lines and proposed construction of new transmission lines.

The review processes are presented below by resource area.

RESPONSE To FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL TVA Heritage Resources Review Process For TVA Transmission Rights-Of-Way Vegetation Maintenance, Line And Pole Maintenance, And New Transmission Line Construction Overview Of Environmental Compliance Process For Transmission Line Maintenance And Modifications The TVA PSO organization routinely conducts maintenance activities on transmission lines in the TVA Power Service Area (PSA).

These activities include, but are not restricted to, ROW re-clearing (removal of vegetation), pole and crossarm replacements, installation of lightning arrestors and counterpoise, and upgrading of existing equipment. Regular vegetation maintenance activities are conducted on a cycle of :3-5 years.

Prior to these maintenance activities, the transmission line area including the ROW is reviewed by technical specialists in the TVA Regional Natural Heritage Project to identify any natural resource issues that may occur along that transmission line.

The TVA Regional Natural Heritage Project maintains a database of some 35,000+ (as of November 2005) occurrence records for protected plants, animals, caves, heronries, eagle nests, and natural areas for the entire TVA PSA, including 201 counties in a sever, state area.

The TVA Heritage database is dynamic, with updates and additions taking place throughout the year.

Only credible records are included in the database, and the sources include the results of field surveys by TVA biologists, publications, museum and herbarium specimens, unpublished reports from biologists outside TVA, data exchanges with the seven state heritage programs overlapped by TVA's coverage area (AL, GA, KY, MS, NC, TN, and VA), and data exchanges with five offices of U.S.

F&WS (Cookeville, TN, Asheville, NC, Athens, GA, Daphne, AL, and Jackson, MS).

Wetland information is maintained by TVA Heritage Resources and includes National Wetland Inventory wetland maps for the entire TVA PSA.

Soil survey maps are also used to identify potential wetland areas.

All records of listed plants or animals, caves, wetlands, or natural areas that are present, or are potentially present, in the transmission line ROWs are taken into consideration when conducting these transmission line reviews.

Other sources considered in reviews include county lists of federally-protected species, the TVA Natural Heritage database described above, aerial photographs and USGS topographical maps.

In addition, high-quality videos taken during low-altitude

RESPONSE To FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL flyovers of the transmission corridors are used to estimate the ecological community types present on the ROW.

Using these available data sources, Heritage biologists identify sensitive habitats where rare plants or animals are known, or likely to occur.

If potential impacts of maintenance activities to plants or animals on the Endangered Species Act are identified, field surveys may be conducted to document presence of the listed species in the ROW, especially if the proposed actions include pole replacement or some other action that would result in ground disturbance.

However, in many other cases where the available data indicate the possibility of listed species being present on the ROW, Heritage specialists assume the species is present and work with PSO staff to avoid impacts to the listed species.

For example, if maintenance activities in the ROW could affect a cave inhabited during part of the year by a bat colony, a restriction may be indicated for the time of year the maintenance activities could take place.

Within streamside management zones, hand clearing, or backpack herbicide application reduce impacts to streams and listed aquatic species.

The width of the streamside management zones vary according to the slope of the surrounding area, the type of stream, and the particular resources that may be present in the stream (listed species).

However, if avoidance is not possible, Heritage specialists consult, as appropriate, with the U.S. F&WS.

Also included in this document is the explanation of class definitions and associated table of mapping polygon colors and the restrictions indicated by those designations used in the cGIS product transmitted to PSO.

Managed areas (MA), ecologically significant sites, and National Rivexrs Inventory for maintenance activities in TVA transmission line ROW MAs are lands held in public ownership that are managed to protect and maintain certain ecological features. Ecologically Significant Sites (ESS) are tracts of privately-owned land that are identified by resource biologists as containing significant environmental resources. National River Inventory (NRI) streams are free-flowing river segments that are recognized by the National Park Service as possessing remarkable natural or cultural values. The TVA Natural Heritage Project maintains a database of all such lands and streams occurring within the seven-state TVA PSA.

As described above, this information is added to and updated frequently.

RESPONSE TO FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL ROW maintenance activity reviews for MA's, ESS's, and NRI streams are completed by utilizing computerized mapping ArcMap graphics software.

If a MA, ESS, and/or NRI stream is located within the 0.5-mile buffer of the subject transmission line, a polygon designating the known or likely extent of that occurrence is drawn on an ArcMap electronic topographic map, and appropriate class restrictions are applied (see table of Class Definitions and Associated Polygon Colors of Sensitive Areas) that represents the area's boundaries within the buffer. A description of the area that includes contact information for the manager of the natural area and also for the appropriate TVA contact, restrictions for maintenance methods, and the subject transmission line name is listed in the corresponding attribute table.

ROW vegetation maintenance and transmission line maintenance are reviewed for potential of these activities to affect natural areas. If all or any portion of a MA, ESS, and/or NRI stream lies within the buffer of the subject transmission line, a polygon is drawn depicting the boundary of such areas. Restrictions on proposed activities (See Attachment 7, Table 1) are determined by the type and location of the MA, ESS, and/or NRI streams, as well as consultation with the area manager or resource specialist. he class and contact restrictions, definitions, and polygon color for both activities are listed in the included table.

After determining the particular class restriction associated with the area, special instructions or comments are added to indicate the importance of the restriction and why it was assigned.

For example, when a portion of a national forest is within the 0.5-mile buffer or crossed by the subject transmission line, a Class 3 restriction is assigned and a comment is added indicating the area manager must be contacted and herbicide use is restricted.

Table 2, in Attachment 7, provides the types of restrictions assigned to transmission line maintenance projects for natural areas. Transmission line projects such as lightning mitigation, counterpoise activities, conveyances, line relocations for state highway department work, and providing delivery points and switches for substations are separate projects and are reviewed for potential impacts to MA's, ESS's, and NRI streams based on the amount and type of disturbance required.

RESPONSE TO FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL (Botany) - State and federal protect plant restrictions for maintenance activities in TVA transmission line ROW Botanical assessments are performed for proposed ROW vegetation maintenance and transmission line maintenance activities.

During the review, botanists identify state and federally listed plants or rare plant community types that occur, or are likely to occur on or near the transmission line ROW.

Identifying the occurrences gives TVA the ability to identify habitats within a proposed project area that are sensitive and potentially require restrictions for particular vegetation management activities.

To identify rare plant and sensitive habitat locations, TVA utilizes the U.S. F&WS' county lists of protected plants, the TVA Natural Heritage database, aerial photographs and USGS topographical maps.

In addition, TVA also have access to videos taken during low-altitude flyovers of the transmission corridors.

These high-quality videos are used to determine the type of plant habitats available on the ROW.

The review process for ROW vegetation maintenance and transmission line maintenance activities is different since they potentially impact vegetation in different ways.

ROW vegetation maintenance consists of vegetation clearing with both herbicides (unless otherwise specified) and mechanical methods.

Any vegetation present in the ROW that is sprayed by herbicides could be acversely affected.

Mechanical clearing has less of an impact since many plants can usually tolerate being cut.

Transmission line maintenance projects like pole replacements potentially impact vegetation when vehicles and equipment drive on (and in) the vicinity of the ROW and the soil and the vegetation are disturbed.

If sensitive plants are likely, field work is often required to confirm their presence.

Frequently however, we assume their presence and make recommendations for different access routes to be taken and TVA notifies appropriate staff about. sensitive areas to avoid.

Restrictions are determined by knowledge of the habitat requirements for rare plants and rare plant. communities that occur within the vicinity of the ROW.

Once a sensitive area is located, a polygon designating the known or likely extent of that occurrence is drawn on an ArcMap electronic topographic map, and appropriate class restrictions are applied (see table of Class Definitions and Associated Polygon Colors of Sensitive Areas).

RESPONSE TO

FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL (Terrestrial Animals) - State and federal-protected terrestrial animal restrictions for maintenance activities in TVA transmission line ROW The TVA Regional Natural Heritage Program keeps track of state and federal-protected species reported from the seven state region.

The terrestrial animal portion of the data base includes all listed birds (breeding and large wintering aggregations),

mammals, reptiles, and amphibians, and some invertebrates (land snails, insects and cave obligate invertebrates).

In addition to certain species of animals, the terrestrial portion of the database also includes records of heronries and caves as they often are used by multiple species, and thus are sensitive habitats.

Each :ransmission line maintenance project is reviewed for the presence of protected terrestrial animals, heronries, and caves.

A database search of the listed animals known from the county (or counties) included in the project area is performed.

The zoologists, using these county lists and animal occurrences from the TVA Heritage database, look for habitats appropriate for these species in their review of the ROW videos.

Heronries and caves within a 3-mile radius from the ROW restrictions will be listed, as appropriate, for likely occurrences of federal and state listed species.

A polygon designating the known or likely exten: of that occurrence is drawn on an ArcMap electronic topographic map and appropriate restrictions are applied (Tables 1 and 2).

Special comments or instructions accompany each entry, as appropriate.

For instance, if a cave located along a power line corridor is scheduled for vegetative maintenance, a 200-fcoot buffer is indicated around the opening of the cave and a "Hand Clearing Only" restriction is applied within the buffer.

If the cave is used by a summer or hibernating colony of bats, appropriate time restrictions, as designated in specific recovery plans for each species, may also be applied.

(Aqua;tic Animals) - State and federal protected aquatic animal restrictions for maintenance activities in TVA transmission line ROW Each proposed transmission line maintenance or ROW vegetation maintenance project is reviewed for the known or likely occurrence of protected aquatic animals in streams, in or adjacent to the transmission line ROW, or in a stream drained by the ROW corridor.

A database search of the listed aquatic animals known from the county (or counties) included in the

The aquatic biologists, using these county lists and animal occurrences from the TVA Heritage database, look for habitats appropriate for these species in their review of the ROW videos.

Once an occurrence or likely occurrence is identified, class restrictions are applied and the appropriate colored polygon is drawn around the resource area on an ArcMap electronic topographic map (Tables 1 and 2).

All transmission line maintenance activities are currently conducted using Best Management Practices as outlined in Muncy (1999).

Special comments or instructions (including designation of specific Streamside Management Zones, as identified by Muncy 1999) accompany each entry, as appropriate.

(Wetlands) - Wetlands review for maintenance activities in TVA transmission line ROW Prior to the performance of any maintenance activities in TVA transmission line ROWs, office-level reviews are conducted by Natural Heritage wetland biologists.

This review includes review of the National Wetland Inventory (NWI) map, county soil surveys, and IVA photos and videos of transmission line structures and ROW.

Potential wetland areas, not indicated on the NWI map, are identified based on interpretation of topographic features, water bodies, soil information, TVA photos and videos and proximity to NWI features. All NWI wetlands or potential wetland areas are superimposed as layers on an ArcMap electronic topographic map (see included maps).

These ArcMap images are sent to PSO, and are accompanied by the Excel spread sheet which lists areas that have been included with the NWI data as areas of potential wetlands and what specific guidelines are to be used in each situation to avoid adverse impacts.

The YWI wetlands are indicated on the ArcMap drawings for both the ROW and a 1-mile diameter buffer area around the ROW.

Poter.tial wetland areas are identified in the ROW, but are not identified in the buffer area, parts of which may be used for ROW access.

If the access route follows an existing road that does not require any repair or upgrading, no further wetland reviews are needed. Repair and upgrading includes, but is not limited to, grading, fill addition, new or upgraded stream crossings, and vegetation removal.

If a new or upgraded access route is necessary, environmental reviews of those particular access areas are conducted as required by the National Environmental Policy Act (NEPA).

The NWI data was compiled using high-altitude aerial photography, some of which is now over 15-years old, with very limited field

RESPONSE TO FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL verification.

Because of this, some of the NWI data may be inaccurate.

The limitations of the NWI data are considered in the performance of transmission line maintenance and ROW vegetation maintenance projects to avoid accidental wetland impacts.

Since there could be wetlands present for which no map evidence or other data currently exists, maintenance crews remain alerted to such things as water on the surface of the ground, soil saturation, the type of vegetation growing in an area, and evidence of present, seasonal or temporary flooding.

In the absence of a ground survey by a wetlands specialist to determine wetland presence and location for ROW vegetation maintenance and transmission line maintenance projects, Best Management Practices, as described in Muncy (1999) are implemented to avoid and minimize potential impacts (see Tables 1

& 2).

These techniques would be implemented in all locations where NWI wetlands and potential wetland areas are indicated on the project maps submitted by the TVA Natural Heritage staff.

Site-specific recommendations for ROW vegetation maintenance and transmission line maintenance projects are provided when needed (see Tables 1 & 2).

In addition, certain activities that may occur during pole replacement in wetlands are regulated under Sections 404 and 401 of the Clean Water Act.

U.S. Army Corps of Engineers (USACE) Nationwide General Permit (NWP) #12 authorizes certain activities related to utility line construction and contains conditions to ensure that impacts to wetlands are minimal.

Section 401 gives states the authority to certify whether activities permitted under Section 404 are in accordance with state water quality standards (Strand, 1997).

A qualified TVA or TVA contract wetlands specialist would be required to delineate the wetland(s) and provide the wetland determination data forms which are required for inclusion in the permit application.

TVA also follows Executive Order 11990 which requires all federal agencies to minimize the destruction, loss, or degradation of wetlands, and to preserve and enhance the natural and beneficial values of wetlands, in carrying out the agency's responsibilities.

Potential impacts to wetlands resulting from ROW vegetation maintenance and transmission line maintenance activities include vegetation damage, soil compaction and erosion, sedimentation, and hydrologic alterations.

These impacts are avoided or minimized during TVA maintenance operations by following the recommendations of the guidelines presented above and implementing all relevant Best Management Practices.

Overview of Environmental Compliance Process for New Transmission Line Construction Prior to selection of potential routes for new transmission lines, PSO identifies the geographic "study area" that includes all potential routes.

Heritage database records of listed plants and animals, caves, natural areas, and NWI wetlands in this study area are provided to PSO at this stage in the planning process.

These and other data are used to support development of specific route alternatives for the new line.

Procedures for environmental review of proposed alternative routes developed with this preliminary information may include field surveys, depending on resource area (briefly discussed by resource) below.

Data obtained from field surveys for new construction projects are used to update the Heritage and wetlands databases so that it is available for future maintenance projects.

If potential construction impacts to plants or animals on the federal Endangered Species Act are identified, Heritage and PSO staffs will make every effort to avoid these impacts. If avoidance is not possible, Heritage specialists consult, as appropriate, with the U.S. F&WS.

(Managed Areas) - Managed Areas, Ecologically Significant Sites, and National Rivers Inventory review of New TVA Transmission Line Cons truc tion A desktop level review of the proposed route alternatives identifies MA, ESS, and/or NRI streams that could be impacted by new transmission line construction.

The TVA Natural Areas Coordinator might contact managers of any non-TVA areas that might be affected to confirm boundaries of the area and management objectives.

Natural Areas input to the NEPA docume:nt prepared for this new construction line project includes the commitment for any mitigation that might be appropriate to protect managed areas from any adverse impacts of construction activities. Field surveys are not usually required, but may be appropriate in some cases.

Because topographic maps are not always accurate, and aquatic habitats can be more accurately described by seeing them, field surveys are required for all proposed routes.

Fie:!d surveys provide information to support recommendations for streanside management zones (Muncy 1999) appropriate for the streams encountered along the route.

These field surveys will be conservative, in that biological samples are not normally taken, and confirmation of the species presence is not required for a determination that the construction may affect the species.

The presence of appropriate aquatic habitat for the listed animals along the proposed route could result in route negotiations and/or specifically recommended mitigation.

As mentioned above, the PSO process for line construction normally allows for reroute negotiations to avoid potential impacts to listed animals.

.NFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL F&WS Question No.6:

Indicate whether TVA is willing to select and use only low-toxic~ity surfactants and other adjuvants during herbicide treatments within stream buffer zones to protect listed aquatic species known or suspected of being present in the streams.

[Thiv may require addition of a BMP to existing plans.]

Surfactants should have LC50's of not less than 20 mg/L for daphnia, trout and [if data are available] mollusks.

TVA RESPONSE:

TVA'sE vegetation maintenance activities involving herbicide and adjuvant application are subject to environmental review procedures previously described in the response to Question #1.

Typically, limited maintenance activities are allowed within the Streamside Management Zones (SMZs).

Levels of protection for SMZs are identified in the environmental review based upon type of watercourse, primary use of water resource, topography, and identification and habitat suitability of threatened and endangered species.

TVA guidelines outlined in "A Guide for Environmental Protection and Best Management Practices for TVA Transmission Construction and Maintenance Activities" provide directions necessary to protect the stream channel or other water body and water quality, and alleviate any potential adverse impacts on threatened and endangered species.

TVA currently utilizes Activate Plus, as manufactured by Terra.,

as an adjuvant to herbicide to improve the performance of the spray mixture.

While the LCso toxicity of this particular surfactant is less than 20 mg/L and lower than recommended by U.S. F&WS, the surfactant contains isopropyl alcohol, which limits its propensity to migrate to water and thus, without direct application to water, limits any probable risks of toxic doses.

Additionally, because of the lack of published field data, it is difficult to determine true toxicity effects of surfactants on aquatic species.

However, TVA would agree to a trial period usage of side-by-side test plots over the next two years of low toxicity surfactants in the SMZs of area transmission lines.

Low toxicity surfactants could include LI700 as manufactured by Loveland Industries, Agri-Dex, as manufactured by Helena Chemicals, and Class Act Next Generation, as manufactured by Agrisolutions.

These particular products currently have some toxicity data available that demonstrate a toxicity range of greater than 20 mg/L.

A trial period usage

RESPONSE TO FISH & WILDLIFE SERVICES' (F&WS) REQUEST FOR ADDITIONAL INFORMATION (RAI) ON NRC'S BIOLOGICAL ASSESSMENT OF TVA'S APPLICATION FOR BFN LICENSE RENEWAL would allow TVA to determine efficacy of these particular surf.ctants in combination with currently used herbicides.

TVA could also adjust their evaluated surfactant use and respond as new products enter the market or LC50 toxicity data becomes available.

Some surfactants may work best with certain types of herbicides and not others due to their solubilities.

Differences in the herbicide's oil or water solubility influence absorption.

Additionally, surfactants perform differently based on the type of plant to be controlled due to differences in wax content and composition, leaf arrangement and architecture, and plant hairs.

TVA plans to engage expert assistance to evaluate the effectiveness of the spray mixtures for optimal vegetation control on the associated ROW SMZs.

Based on the surfactant evaluation, TVA would consider utilizing these products on an extended schedule in the BFNP SMZs, as well as wider scale use across the TVA region.

S9I.1 SHAPE FID 535225 As stated above, the Heritage staff has specific guidelines for interpretation of the Arc-Map data when project reviews are performed. For example, if the Heritage database contains a plant record within 5 miles of the proposed project (in this case, within 5 miles of the ROW corridor), botanical personnel conside-it possible for that species to currently inhabit the project area. Other disciplines have different requirements; for example, the search radius for aquatic animals is 10 miles.

Also as described above, Transmission & Power Supply video flyovers are used to determine whether or not the habitat might be present for a given plant along the subject stretch of ROW. For example, a 5-mile search might pull up many possible plants from a reach of ROW, but if the video flyover shows row crops, the row crop area would probably not be marked for special ROW management techniques based on the rare plant record. However, if the video flyovers show anything similar to appropriate habitat, to be conservative the entire possible habitat area is marked With a polygon on the file that is sent to TPS, along with special instructions designed to protect the plant (for example, don't use chemicals; bush-hog instead).

Because of the record of the federally-listed Monkey-Face Orchid, Patricia Cox and Kelly Baxter visited the site before the plants were in flower. After being contacted by the State of Tennessee Heritage staff regarding the presence of the orchids in the ROW, Patricia Cox and Paul Durr revisited the area and found plants occurring in the ROW and growing in the nearby woods. Notes taken from the subsequent field visit are reproduced below:

Field Notes for Great Falls - Pikeville Transmission Line Demolition Project, 23 August 2004

1. UTM:16S 0642661/3939236 At the junction of the de-energized line and the "new" line there were eight flowering and many sterile plants oFPlatanthera integrilabia (federal candidate) as well as P. ciliaris growing in the ROWbetween the junction and structure 56. Platanthera integrilabia, Cyperpedium acaule, and Parnassia asarifolia were growing at the edge of the woods near a fire line.
2. UTM: 16S o642699/3939336 On the I)e-energized line...between structures 517 and 518 (closer to 517)...There were SIX Platanthera integrilabia plants flowering and many more sterile plants were found in the right of way (very grown up with red maple). These plants were marked with yellow tape.

3.

UTM: 16S o642689/3939302 Eighteen Flowering and many sterile plants were found in sphagnum at the edge of the woods adjacent to structure 517. The plants were within 1oo yards of the structure. The taxa associated with P.

integrilabia were: Acer rubrurm, Viburnum nudum, Alnus serrulata, Itea virginica, Osmunda cinnamomea, Osmunda regalis, Oxypolis rigidor, Cinna arundinacea, and Dicanthelium acuminatum.

Area w-s flagged with yellow tape.

4.

UTM: i6S o643007/3938942 Between structures 514 and 515 on the de-energized line, TWO flowering and many sterile plants of P.

integrilabia were found growing at the edge of the woods in sphagnum. They were growing in a large population of New York fern, Thelypteris novaboracensis. The Parnassia was also seen at this site.

Plants were flagged with yellow tape.

Platant;zera ciliaris and Bartonia virginica were found in abundance along this stretch of ROW between structures 514-515.

5. On the left side of the ROW, adjacent to the woods between the road and Structure 516 was one small tree of I'opulus grandidentata, a species of SPCO in TN.

B. Bald Eagle Nesting Sites in Proposed Transmission Line Corridors for Clay and Lowndes Counties, Mississippi In February 2005, a transmission line for the potential development of the Golden Triangle Industrial Park was proposed through Clay and Lowndes Counties, Mississippi.

The proposed transmission line routes were drawn into ArcMap (shown in yellow, orange, and red) and a 3-rnile buffer was added around the proposed routes (shown in purple). The Heritage database layer showed two terrestrial animal records (Black-knobbed Map Turtle and a Heronry) that fell within 3-miles of the proposed routes. Based on the proposed actions and the distances from those actions, there was no concern for either the turtle or the heronry. A Bald Eagle nest location was additionally noted 3.5 miles from the closest proposed route - the distance of this nest from the :proposed actions was also judged to be sufficient (based on U.S. Fish & Wildlife Service guidelines) for the construction activity not to affect any birds that may be present.

A field visit by Hill Henry (Terrestrial Zoology Specialist for TVA Heritage) on February 16, 2005 confirmed two new locations of bald eagle nests. An adult bird was seen on the southern nest, while only a nest structure was found at the nor:hern location. However, the landowners said they had seen adult birds using the northern nest recently.

These two nest locations were plotted on the map, and using the buffer tools in ArcMap, buffers 0.5 mile (blue) and I mile (purple) in radius were created around the bald eagle locations of concern. We were than able to see where they occurred in relation to the different routes that were being proposed.

1<1 Initially, the right-of-ways of the first three alternative routes crossed the 0.5 mile buffer zone of at least one of the bald eagle nest locations. After a project meeting in Chattanooga, TN on February 28, 2005 a different route was chosen, (ia black), that avoided all the bald eagle nest locations by at least I mile.

Colbert Fossil Plant Mooring Cell Replacement, Colbert County, AL In May 2005, a walkway and mooring cell at Colbert Fossil Plant were damaged by a barge. The Colbert Barge Unloading Facility is located in Wilson Tailwater/Pickwick Reservoir, where several state and federally-listed mussel species are known to occur. Using ARC-Map (pictured below), a ten mile buffer was drawn around the plant to determine what state and/or federally listed aquatic animal species were present. This resulted in a table including one crayfish, one shrimp, five fish, seven snails, and 44 mussels (ATTACHMENT 2). However, TVA biologists determined that several of these species would not be affected because they are found in caves or tributaries to the Tennessee River and not the river itself. The only species possibly affected by repairing the barge unloading facility would be the mussel and snail species, which could exist within the footprint of the damaged mooring cell. After informal consultation with the Daphne, Alabama office of the USFWS, it was decided that a mussel survey would be conducted to determine whether or not these listed species were present within the project area. The mollusk specialist in the Alabama Department of Conservation and Natural Resources, Division of Wildlife and Freshwater Fisheries (W&FF) was consulted to suggest the best person to conduct the mussel survey. A TVA aquatic biologist and U.S. Fish & Wildlife Service (F&WS) and W&FF personnel were on call during a weekend to hear whether or not there wvere endangered species in the area to remove. If listed species were present, they were to be relocated out of the project area to an area specified by FWS. However, the mussel survey performed by Paul Yokley, malacologist, Yokley Environmental Consulting Service, revealed that no state or federally-listed mussels were present within the barge unloading facility. Based on those findings we were able to say this project would have no effect on listed mussel or snail species and the mooring cell was repaired.
