On February 1, 2012, the Ohio Environmental Protection Agency (Ohio EPA) finalized the much anticipated general air permit (GP12) for well-site production operations. GP12 covers many of the air emission sources that are typically associated with shale gas well sites, including: glycol dehydration units (no more than 2 per site), stationary natural gas-fired internal combustion (IC) engines (≤ 1,800 hp total), stationary diesel-fired IC engines (≤ 250 hp total), fugitive equipment leaks, vertical fixed roof storage tanks (≤ 39,894 gallons/tank & ≤ 252,000 gallons total), and a flare/combustor (≤ 250 MMBtu/hr maximum capacity, ≤ 10 MMBtu/hr during normal operation) for emission control.
To take advantage of GP12, facilities must certify they can meet the GP12 qualifying criteria as part of a streamlined permit application package. Ohio EPA expects to issue general permits within 30 days of application submittal, and the $2,300 permit fee will be invoiced upon permit issuance.
Note that GP12 does not cover drilling or well completion operations, which are governed by the Ohio Department of Natural Resources, as these operations are generally exempt from air permitting requirements in Ohio. Also, Ohio EPA is looking to develop a new general permit for natural gas compressor stations over the next several months.
