Cheatham County Generation Site EIS Scoping Report

Appendix C Summary of Scoping Comments

Tennessee Valley Authority

I own a house at the corner of Newland Hollow Road & Lockertsville Rd in Ashland City. TVA is wanting to build a methane gas site, lithium battery site and 12 miles of gas line along this area. I have lived here since 1999 and bought this property because it was quiet, rural, full of nature and animals as well as a great neighborhood. I am opposed to this site, as many others, due to the hazardous conditions that would become of this area from air quality to our waterways possibly being contaminated with what TVA is proposing. This isn’t even to mention how loud it would be and dealing with constant lights. I know in the past, when there have been leaks in the waterways, it hasn’t been dealt with immediately. I know if there were an explosion, this would be catastrophic, possibly more so than other areas where explosions have taken place and burned hundreds of acres. You also will make the flooding situation that happens around these parts, much worse. Please use the coal sites that you are shutting down rather than having new sites that will be nothing more than a nuisance for this community. Ashland City gets nothing from you coming here. Nashville will get the electricity while Ashland City gets the headache

I am a local resident (less 1/4 mile) of the proposed CHG site. There are obvious questions that arise when hearing of a turbine combustion plant and the words methane gas is mentioned. The first issue that comes to mind is noise for local residents. In talking with the project manager he was explaining the new technology with the turbines to be used and gave examples where they were already in place. Hopefully, there can be examples provided and possibly data related to the decibel levels surrounding those plants in existence. Another issue would be the effect to property values for those residences within close proximity to plants of this nature. I can assure you the county will believe my property value will go up, but someone would have to convince me with relatable data proving there would be no effect. I was also told that there is no reason for any type of buffer zone for residences close to this site. Supposedly the site would be safe and not cause any danger to the areas surrounding the site. Any correspondence or data related to this would be appreciated for residents to feel more warm and fuzzy without having to constantly worry about what could happen.One issue related to this project will be the traffic generated on Lockertsville Road by large trucks. I can assure you the road was not created to handle such traffic. There will be a danger to those that travel the road every day, such as myself. Hopefully you can understand my hesitance in seeing this project go through so close to my home. I will be retiring in a few years and the last thing I want to worry about in my supposed golden years is to worry about my and my family’s safety as well as worrying about running into 18-wheelers on a narrow road. And i certainly don’t want to see my investment in living in a fairly quiet country area be devalued because of something such as this plant. Thank you for understanding my concerns neutral Steve Johns 37015

Would the TVA be opposed to the community resourcing their own environmental study, at their own expense, and who would we contact to stay in communication with in your office to do so?

Comment 18: How does TVA plan to address the off-gassing of the lithium-ion batteries? How do you plan to control thermal runaway in the lithium-ion batteries (overheating that ignites the off-gassing). How well will the lithium-ion batteries perform in the hot summer when they are known for their overheating, ignition issues and ambient temperature limits? Comment 19: Include any and all seismic activity protections identified during the geotechnical studies of the sites into the Engineering, Procurement and Construction (EPC) contract. Include emergency preparedness in the plant’s operational plan for seismic activities as well as the possibility of karst features opening during a seismic event. Comment 20: At no point in the planning, construction or operation of the proposed Cheatham County CT & BESS site should water be withdrawn from Sycamore Creek, Spring Creek, or any of their tributaries located on the proposed site. At no point should any wastewater, process water or stormwater that originates on the proposed site be discharged directly to Sycamore Creek, Spring Creek, or any of their tributaries even if allowed by permit. All water originating on site should be retained for as long as possible and released upgradient to any drainage feature to promote infiltration. This is especially important as groundwater recharge at the site will be heavily impeded by the amount of impervious surface that will be installed to support the CTs and the BESS. Comment 21: As part of the EIS scoping process, engage local water and sewer utility providers to ensure those systems can support the proposed Cheatham County site before and during construction and during operation going forward. If utility providers cannot support the proposed alternative, the plan for a CT & BESS should be abandoned. If it is not, TVA should be responsible financially for all system upgrades that may be required. Comment 22: As part of the EIS scoping process, engage local emergency management agencies and first responders to ensure those entities can support the proposed Cheatham County site before and during construction and during operation going forward in case of a fire, explosion or other emergency. If emergency response entities cannot support the proposed alternative, the plan for a CT & BESS should be abandoned. If it is not, TVA should be responsible financially for all equipment upgrades and additional training that may be required. Comment 23: In addition to obtaining any Aquatic Resource Alteration Permits (ARAP) that are required and utilizing all TDEC recommended BMPs possible for stream crossings or other impacts, treat all Wet Weather Conveyances (WWC) located on the subject property as streams to prevent the discharge of sediment to Spring Creek, which is impaired and on the 303(d) list, and Sycamore Creek, which is currently fully supporting and is utilized extensively for recreation. I appreciate your time in reviewing these and all other comments received regarding the proposed Cheatham County Generation Site project. I hope to see these and other environmental impacts addressed completely and objectively in the draft EIS and look forward to reviewing a document that is compliant with NEPA in rule and in spirit. Sincerely, Stephanie Henry, Cheatham County, TN Resident Comment 15: Due to the dramatic increase of impervious surfaces anticipated to construct the proposed Cheatham County site, TVA should include features that will promote water infiltration to support groundwater recharge. The site and surrounding areas have dozens of spring-fed creeks that could be affected by decreased recharge rates. Examples include pervious concrete and rain gardens, among many others. Comment 16: Although the next NEPA-required public comment period won’t occur until the draft EIS is complete, initiate public outreach efforts in the form of a town hall-style meeting to present information to the local community. Based on my personal experience and conversations with other attendees, the June 21, 2023, open house meeting left the public frustrated. Information wasn’t formally presented, the venue was too small for the turnout, and asking questions for different impact areas/topics required trying to speak with multiple TVA representative who weren’t clearly identified by area of expertise. Additional informational meetings, including question-and-answer sessions, will help to inform the local community who currently feel like TVA didn’t properly advertise the June 21st meeting and are being secretive about the project. Comment 17: Consider in detail realistic ways to prevent or extinguish lithium-ion battery fires. According to TVA representatives on June 21st, each shipping container-style case will include intrinsic fire extinguishing methods that will deploy automatically if needed. However, lithium-ion battery fires are notorious for fast generation and difficult extinguishing. If there were a battery fire or explosion due to malfunction or thermal runaway, what would TVA’s plan be to control the fire and prevent it from spreading to surrounding brush, forest, agricultural areas and homes?
