SUBJECT:
Request for Farmland Conversion Impact Rating - Proposed Clinch River Small Modular Reactor Project, Roane County, Tennessee
Dear Mr. Slabaugh,
AECOM is working with the Tennessee Valley Authority (TVA), through Ruth Horton (865-632-3719), in the preparation of an Environmental Report for an Early Site Permit (ESP) Application to the Nuclear Regulatory Committee for a proposed 800-megawatt (MW) small modular reactor (SMR) facility at a proposed site in Roane County, Tennessee. The proposed facility would be located on approximately 935 acres of federal land, the Clinch River Nuclear (CRN) Site, located approximately 10 miles southwest of the Oak Ridge business district (Figure 1). The proposed construction activities would occur within the proposed CRN Site and the adjacent approximately 196 acre Barge/Traffic area (Figure 2).
TVA is in the process of conducting investigations and preparing the NEPA compliance documentation for the proposed project. This documentation will include a comprehensive analysis of pertinent environmental impacts, including prime or unique farmlands and an analysis of project alternatives. This letter is being submitted under the provisions of the Farmland Protection Policy Act.
The proposed CRN Site has been federal property since 1941. The only soil survey information for the proposed site is the 1941 Roane County Soil Survey. The proposed CRN Site and nearby Barge/Traffic area contains the following soils as shown in Figure 2:
First-class soils (good to excellent cropland) - 0 acres Second-class soils (fair to good cropland) - 277.7 acres Third-class soils (poor to fair cropland) - 265.4 acres Fourth-class soils (best suited to pasture) - 383.3 acres Fifth-class soils (best suited to forest) - 204.5 acres Portions of the CRN Site have been disturbed during previous site activities, including extensive excavation. 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.
Approximately 240 acres of the CRN Site were disturbed during site preparation for the CRBRP. Site preparation activities included leveling a ridge that originally reached 880 feet above mean sea level (msl) to 780 msl, excavation of the construction area, and installation of various structures and pads. The excavated area totaled approximately 24 acres in extent and extended to as much as 100 feet in depth.
Approximately three million cubic yards of earth and rock were excavated during the site preparation. The project was terminated in late 1983 and 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 ofriprap in larger ditches, installation of culverts to direct water from steep slopes, and modification of the holding ponds for long term stability. The 80 foot by 80 foot crane pad was left in place. The excavated area was partially backfilled in a manner to sustain site drainage. Level areas of the CRBRP Site were graded and A-1
AECOM Request for Farmland Conversion Impact Rating compacted. The areas of the CRN Site most heavily disturbed during the CRBRP Project are shown in Figure 2.
The majority of the CRN Site is located within the 7.5 minute U.S. Geological Survey Elverton Quadrangle. The eastern portion of the site is located within 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 (Figure 3).
2 Enclosed is Form AD-1006, the Farmland Conversion Impact Rating Form, with Parts I and Ill completed and a map showing soil types and farmland classification of the proposed project site (Figure 2) based on the original 1942 Soil Survey data. To ensure compliance with the Farmland Protection Policy Act and to support the NEPA process, TVA requests that Natural Resources Conservation Service review the enclosed project-specific information and complete Parts II, IV, and Von the enclosed Form AD-1006.
TVA staff will forward to your office a copy of the draft NEPA document, when it is available for distribution, along with a request for comments.
If you have any questions regarding this proposed project, please contact me at 864-234-8913 (bobbie.hurley@aecom.com) or Ruth Horton at 865-632-3719 (rmhorton@tva.gov).
Sincerely, Roberta A. Hurley Senior Operations Manager A-2
