Moore County officials provided a detailed update on the county’s 200-megawatt solar farm during the Planning and Zoning Commission meeting on Tuesday, Oct. 7, addressing resident concerns about smoke, stormwater management, and road conditions at the construction site.

Environmental consultant Tony Grow, hired by the county to oversee the project, reported that state regulators have found the work to be in compliance with Tennessee Department of Environment and Conservation (TDEC) rules. Grow said inspections occur three times a week, focusing on stormwater runoff, soil erosion, and air quality.

Grow noted that the solar farm includes 74 stormwater outfalls, all of which must be tested after rainfall, particularly because Hurricane Creek, which drains into Tims Ford Lake, is an Exceptional Tennessee Waterway requiring heightened protections.

“We’ve made plenty of phone calls and checked every box we can,” Commission Chairman Dexter Golden said. “They’re not stepping outside any legal bounds at the moment.”

Residents raised concerns about smoke from on-site brush burning, heavy traffic, and mud and gravel tracked onto county roads. Oak Hills Drive resident Michael Hamby described recent conditions: “Last week visibility and the air quality was ruined by the solar ranch. They had multiple large brush fires going at once, and the wind was in an unfavorable direction.

“I intend to go to meeting in a week or so with the county. … I think that’s y’all’s job and the mayor’s job to make sure they don’t mess this up.”

The Metro Council will meet at 6:30 p.m. Monday, Oct. 20, at the American Legion Building at 119 Booneville Hwy. in Lynchburg.

Officials said contractors have been instructed to slow down, enhance sediment fencing, and utilize a street sweeper to handle rock and gravel on roadways. County leaders also stressed that Silicon Ranch is contractually obligated to repair any damage to county roads caused by construction equipment.

The solar farm was approved by the Metro Council on Nov. 18, 2024. It is being built on 3,400 acres purchased from the Cumberland Springs Land Company, will utilize 1,800 acres for solar panels; approximately 480 acres have been cleared.

Silicon Ranch will build, own, and operate the facility, providing roughly 20 megawatts of power to Jack Daniel Distillery, covering about three-quarters of the distillery’s electricity needs through TVA’s Green Invest program.

During the meeting, Grow and the commissioners highlighted that the economic benefits to the county are limited beyond tax revenue and some construction spending. Currently, approximately 200 workers are on-site, most of whom are from out of state, with roughly 40 full-time maintenance jobs expected once the farm is operational.

County leaders emphasized that the project is under constant oversight, including weekly safety briefings, environmental inspections, and a decommissioning plan in case the site is abandoned.

“We take every call seriously,” Golden said. “We’re doing everything we can as a county to make sure the people coming in are doing right.”

The Metro Council approved the solar farm agreement with Nashville-based Silicon Ranch on Nov. 18, 2024, resolving a multi-year negotiation over permit fees and clearing the way for construction to continue.

Understanding Air Quality
in Moore County

During Tuesday’s Planning and Zoning meeting, environmental consultant Tony Grow noted that Silicon Ranch is bound by the Clean Air Act, but Moore County’s status as an air quality attainment area limits additional restrictions.

What is an air quality attainment area? An attainment area is a region where pollution levels for certain pollutants meet the National Ambient Air Quality Standards (NAAQS) set by the EPA.

Areas are classified as:

  • Attainment: Meets NAAQS
  • Nonattainment: Exceeds NAAQS
  • Unclassifiable: Not enough data to determine compliance
  • NAAQS protect public health and welfare
  • Primary standards: Protect human health, including sensitive populations like children and the elderly
  • Secondary standards: Protect public welfare, preventing damage to buildings, crops, animals, and visibility

The six criteria pollutants monitored under NAAQS:

  • Ground-level ozone (O₃)
  • Particulate matter (PM)
  • Lead (Pb)
  • Carbon monoxide (CO)
  • Nitrogen dioxide (NO₂)
  • Sulfur dioxide (SO₂)

Enforcement and monitoring:
The EPA sets and periodically updates NAAQS, while states monitor pollution levels to ensure compliance. An area can be in attainment for one pollutant but nonattainment for another.

Moore County currently meets the standards for the pollutants measured, which means Silicon Ranch’s operations are under federal air quality rules but face limited local restrictions.
