Ohio

Ohio (Utica/Marcellus) uses general permits for upstream and midstream oil and gas. Well-site GPs 12.1 and 12.2 (2014) are no longer available for new sources as of May 7, 2024 (the effective date of NSPS OOOOb) but are renewed for non-OOOOb facilities; GPs 12.3.1 and 12.3.2 cover sources constructed, modified, or reconstructed after December 6, 2022 and incorporate OOOOb. Midstream compressor stations use a family of unit-specific GPs (engines, dehydrators, flares, compressors, leaks, tanks, truck loading, pigging), with supplemental information showing the project won't trigger major NSR.

• Well-site production GP 12.1 / 12.2 (legacy)

South Dakota

DANR's air permitting and application pages list no oil and gas specific air permits. Oil and gas sources follow the minor source and Title V thresholds and applicable federal NSPS/NESHAP (adopted by reference in ARSD 74:36:07 and 74:36:08). Oil and gas wells on tribal lands fall under EPA Region 8.

Tennessee

TDEC's air permit pages list no oil and gas specific general permit or PBR. Oil and gas sources follow the construction and operating permit requirements above and applicable federal NSPS/NESHAP.

Texas

Oil and gas sites follow the same tiered path: de minimis, then PBR (Subchapter O), then the Air Quality Standard Permit for Oil and Gas Facilities, then a case-by-case NSR permit. Major sites may use Title V general operating permits GOP 511 or 514.

• PBR 106.352: Oil and Gas Handling and Production Facilities

Washington has no meaningful oil and gas production program in Ecology's air permitting pages. Refineries and large energy facilities are handled through NOC/AOP permits by the local agency, Ecology, or EFSEC.

West Virginia

West Virginia (Marcellus/Utica) uses general permits for upstream and midstream gas. G70-E covers natural gas production facilities at the well site and replaces G70-A through G70-D (G70-D registrations are automatically covered). G35-E (issued September 5, 2024) covers natural gas compressor and/or dehydration facilities and replaces G30-D and G35-A/C/D. G33-A covers small compressor engines. DAQ's well pad guidance explains when a permit is generally triggered and which NSPS (OOOO/OOOOa/OOOOb) applies by date. Well completion notifications are due at least 2 days before each completion.

Wisconsin

Wisconsin has no oil and gas production air permit program in DNR's air permit pages. Industrial (frac) sand mines and processing plants use the standard construction and operation permits and the nonmetallic mineral general permit.

Wyoming

Wyoming law (W.S. 35-11-801(e)) lets oil and gas production sites that meet BACT begin construction without prior authorization. Since 1997, DEQ's Oil and Gas Production Facilities Permitting Guidance has defined BACT for these sites; the May 2016 (8th) update merged the former Statewide and Concentrated Development Areas into one area (control levels are in the guidance entry). The Upper Green River Basin (UGRB) was designated an ozone nonattainment area in 2012 under the 2008 standard; EPA found it attained in 2016, and DEQ began redesignation in December 2024. In 2024 DEQ adopted an emergency rule to incorporate EPA's NSPS OOOOb methane rule.
