Measures to avoid, minimize, and mitigate adverse effects will be identified and evaluated in the EIS. Anticipated Permits and Other Authorizations TVA anticipates seeking required permits or authorizations, as appropriate. The construction of the natural gas pipeline(s) would be subject to Federal Energy Regulatory Commission (FERC) jurisdiction and additional review will be undertaken by FERC in accordance with its own NEPA procedures. TVA’s proposed action to construct a CT and BESS may also require issuance of an air permit under the Clean Air Act, an Individual or Nationwide Permit under section 404 of the Clean Water Act; section 401 Water Quality Certification; conformance with Executive Orders on Environmental Justice (12898), Wetlands (11990), Floodplain Management (11988), Migratory Birds (13186), and Invasive Species (13112); and compliance with section 106 of the National Historic Preservation Act, section 7 of the Endangered Species Act, and other applicable local, Federal, and State regulations. Public Participation and Scoping Process Scoping, which is integral to the process for implementing NEPA, provides an early and open process to ensure that issues are identified early and properly studied; issues of little significance do not consume substantial time and effort; the draft EIS is thorough and balanced; and delays caused by an inadequate EIS are avoided. TVA seeks comment and participation from all interested parties for identification of potential alternatives, information, and analyses relevant to the proposed action in this EIS. Information about this project is available at https:// www.tva.gov/NEPA, which includes a link to an online public comment page. Comments must be received or postmarked no later than June 20, 2023. Federal, State, local agencies, and Native American Tribes are also invited to provide comments. Please note that any comments received, including names and addresses, will become part of the project administrative record and will be available for public inspection. TVA plans to have an open house on
that can successfully integrate increasing amounts of renewable energy sources while ensuring reliability. One of the purposes of the proposed action is to facilitate the integration of solar onto the electric grid and thereby advance TVA’s decarbonation goals. The need for the Proposed Action is to ensure that TVA can meet required year-round generation and maximum capacity system demands and planning reserve margin targets. By constructing and operating a CT with a BESS interconnected to the transmission system at the same location, TVA would continue providing dispatchable and reliable energy to the people of the Tennessee Valley at the lowest feasible cost with fewer environmental impacts than the current generating capacity that is being replaced. The addition of the proposed 400 MW-hour BESS could also help TVA maintain grid stability and reliability as generating assets with greater minute-by-minute variability are integrated into TVA’s transmission system ( e.g. wind and solar generating assets). Preliminary Proposed Action and Alternatives TVA anticipates that the scope of the EIS will evaluate a No Action Alternative and an Action Alternative. The No Action alternative provides a baseline for comparing against the Action Alternative. Under the No Action Alternative, TVA would not develop the TVA-owned property in Cheatham County for energy generation. The Action Alternative would evaluate the development of the CHG property for construction and operation of a CT interconnected with a BESS. The CHG property would also include an approximately 13-acre pollinator habitat along Sycamore Creek. Whether these or other alternatives are reasonable warranting further consideration under NEPA would be determined in the course of preparing the EIS. Related actions, such as the construction of an approximately 12-mile natural gas pipeline lateral and off-site transmission lines, will also be assessed in this EIS. The pipeline facilities to bring gas supply to the CHG property would, to the extent practicable, be located within or adjacent to an existing pipeline right of way. Anticipated Environmental Impacts The EIS will include a detailed evaluation of the environmental, social, and economic impacts associated with implementation of the proposed action. Resource areas to be addressed in the EIS include, but are not limited to: air quality; aquatics; botany; climate
facilities over 16,000 miles of transmission lines. Generation Asset Planning
In June 2019, TVA published an IRP, which was developed with input from stakeholder groups and the public. The 2019 IRP evaluated six scenarios (plausible futures) and five strategies (potential TVA responses to those plausible futures) and identified a range of potential resource additions and retirements throughout the TVA power service area, which encompasses approximately 80,000 square miles. The target supply mix adopted by the TVA Board through the 2019 IRP included the potential retirement of 2,200 MW of coal-fired generation by 2038. The IRP acknowledged continued operational challenges for the aging coal fleet and included a recommendation to conduct end-of-life evaluations during the term of the IRP to determine whether retirements greater than 2,200 MW would be appropriate. Following the publication of the IRP, TVA began conducting these evaluations to inform long-term planning. TVA’s recent evaluation confirms that the aging coal fleet is among the oldest in the nation and is experiencing deterioration of material condition and performance challenges. Consistent with aging coal fleet evaluation, TVA made a decision to retire the first CUF unit by the end of 2026 and the second unit by the end of 2028. Generation from the proposed project would replace a portion of the capacity of the second CUF unit to be retired by 2028. Generation from the proposed project would also be consistent with the target supply mix in the 2019 IRP that aims the addition of up to 5,200 MW of simple cycle capacity by 2028 to facilitate the integration of solar onto the TVA bulk power system. Project Purpose and Need The TVA-owned land for TVA’s proposed project is in Ashland City, Cheatham County, Tennessee, which is approximately 22 miles northwest of Nashville. The total property is approximately 285 acres with the proposed project footprint covering a footprint of approximately 75 acres. TVA’s EIS would evaluate the proposed action to replace a portion of the 1,450 MW generation capacity of the second CUF unit planned for retirement in 2028 with up to 900 MW of generation capacity from CHG. The purpose of the proposed action is to help provide generation to support continued load growth in the Tennessee Valley and TVA’s decarbonization goals. TVA needs flexible, dispatchable power
