Georgia EPD drafts Title V permit changes for Thomaston gas compressor station

Georgia EPD's Air Quality division has drafted a Title V permit amendment for Southern Natural Gas Company's Thomaston Compressor Station (Permit No. 4922-293-0025-V-05-1). The draft covers construction of a new natural gas-fired combustion turbine, an emergency generator and a turbine fuel line heater at the facility.

A June 26, 2025 EPD notice laid out the project in more detail: a SIP construction permit and Title V significant modification adding a new turbine, emergency generator and fuel heater, along with engine tuning. EPD's figures show the changes would increase particulate matter by 2.48 tons per year, raise sulfur dioxide by 1.28 tons per year and increase carbon monoxide by 16.74 tons per year, while cutting VOC emissions by 8.30 tons per year, NOx by 5.56 tons per year and total hazardous air pollutants by 21.90 tons per year.

A later EPD notice, dated November 6, 2026, describes the same proposed modification for the Upson County facility in more specific terms, identifying the new unit as a Solar Taurus 70 stationary turbine rated at 11,367 horsepower and listing the same projected emissions changes, including a 14.58 ton-per-year drop in formaldehyde, the facility's highest-emitted hazardous air pollutant.
