What are the locations and age of the substations that this site would connect to? What modifications will be required?
The site will require three 161 kV transmission lines looped into the switchyard to connect the generation to the broader TVA transmission system. The transmission line routes and substations for these loops are still being identified. The approximately 8-mile natural gas pipeline lateral that would supply CHG would be developed, owned, and operated by a separate pipeline operator. The pipeline operator will be required to apply with FERC for the construction and operation of the pipeline as required by the Natural Gas Act. The application triggers a FERC environmental review under NEPA, independent of the NEPA review that TVA will complete. FERC also ensures that the applicant certifies that they will comply with Department of Transportation safety standards. TVA’s contractual relationship with the pipeline operator would be through a Precedent Agreement, which establishes a framework for the development of the pipeline. Precedent Agreements are structured as “stage - gate” agreements, definin g certain conditions that must be met before pipeline development work can progress. These conditions may include completion of the TVA NEPA review, TVA Board approval, and FERC approval of the pipeline. Importantly, pipeline construction cannot begin until all of these conditions have been met, and TVA’s commitment to become a firm shipper on the pipeline is contingent upon pipeline completion and FERC’s authorization to place it into service. Routing of the Transmission Lines (TL) required to support this proposed project is currently being determined and developed. This information (along with the required NEPA review of the proposed routing) will be included in the Draft Environmental Impact Statement (DEIS) targeted for release to the public no earlier than the end of Calendar Year (CY) 2024. In discussions with the Pleasant Valley Utility District (PVUD), TVA has confirmed the ability to supply TVA with the required water volume specified. Any questions concerning water supply capacity should be posed to PVUD. For clarification, there is no process water discharge required for this proposed facility, therefore the only water management required onsite would be for stormwater runoff. If the proposed facility is constructed
What is the current age and capacity of the existing pipelines to which the new pipelines will be connecting? When were they last inspected, and by whom?
What is the proposed route of the new 45 miles of transmission lines? How many structures will require a relocation or demolition? How many private landowners will be affected? What is TVA going to put in place to protect the source water for PVUD? The scoping report states the site may require up to 100 gallons per minute from Pleasant View Utility District during peak cooling hours. What is considered peak cooling times? What is the current capacity of PVUD? As summers continue to climb into
