Results for “flare requirements”
- StateWest Virginia air permitsWest Virginia Department of Environmental Protection (WVDEP). WVDEP's Division of Air Quality issues construction, modification, relocation, and temporary permits under 45CSR13 for stationary sources above the rule's thresholds, plus Class I and Class II general permit registrations (filed through the Electronic Submission System), PSD permits (45CSR14), nonattainment NSR permits (45CSR19), and Title V operating permits (45CSR30). Fees are under 45CSR22. A Permit Determination request confirms whether a permit is needed. West Virginia has extensive oil and gas general permits: G70-E for well sites and G35-E for compressor and dehydration facilities. There are no local air agencies.
- StateNew Hampshire air permitsNew Hampshire Department of Environmental Services (NHDES). NHDES is the sole permitting authority statewide (no local air agencies). New or modified sources above the device/source thresholds in Env-A 600 need a Temporary Permit (construction, up to 18 months), followed by a State Permit to Operate (up to 5 years) or a Title V Operating Permit (5 years). Alternatives include General State Permits for emergency engines and Permit-by-Notification for rock crushers. Although New Hampshire is in attainment for ozone, it is in the Northeast Ozone Transport Region, so nonattainment NSR applies to major NOx and VOC sources (Env-A 618); PSD is under Env-A 619.
- StateMassachusetts air permitsMassachusetts Department of Environmental Protection (MassDEP). MassDEP requires a Plan Approval before constructing or modifying facilities that emit air contaminants (310 CMR 7.02), as a Limited Plan Application (LPA) or Comprehensive Plan Application (CPA) depending on size, unless exempt. Alternatives include Permit-by-Rule (310 CMR 7.03) and the mandatory Environmental Results Program (ERP, 310 CMR 7.26) for certain sectors. All new units must meet BACT (or LAER where nonattainment NSR applies). Major sources need a Title V Operating Permit under 310 CMR 7.00 Appendix C. MassDEP administers PSD by EPA delegation under 40 CFR 52.21.
- StateOregon air permitsOregon Department of Environmental Quality (DEQ). Oregon DEQ issues Air Contaminant Discharge Permits (ACDPs) for minor sources and for new major sources/major modifications, plus Title V operating permits for major sources. Which ACDP applies depends on the source category in the Table of Activities and Sources (OAR 340-216-8010, Table 1): Part A sources qualify for a Basic ACDP, Part B for a General, Simple, or Standard ACDP, and Part C must get a Standard ACDP. Permits carry Plant Site Emission Limits (PSELs) compared against Significant Emission Rates (SERs). Many sources need a Notice of Construction even without a permit (OAR Division 210), and every permit needs a Land Use Compatibility Statement. Cleaner Air Oregon adds facility risk assessment for toxic air contaminants. LRAPA permits in Lane County; EPA Region 10 permits in Indian Country and on the Outer Continental Shelf.
- StateWyoming air permitsWyoming Department of Environmental Quality (DEQ). Wyoming DEQ's Air Quality Division requires a construction permit before construction or modification of a source begins (WAQSR Chapter 6, Section 2(a)(i)). DEQ says Chapter 6 has no de minimis emission levels; instead, Section 2(k) lists specific activities that do not need approval. Oil and gas production sites that use Best Available Control Technology (BACT) may begin construction without prior authorization under W.S. 35-11-801(e), and DEQ's Oil and Gas Production Facilities Permitting Guidance defines that BACT. Major sources need PSD (Chapter 6, Section 4), nonattainment NSR (Chapter 6, Section 13; Upper Green River Basin ozone area), and a Title V operating permit (Chapter 6, Section 3). Applications are submitted through the IMPACT portal, and drafts are posted on OpenAir. EPA Region 8 is the permitting authority in Indian Country.
- StateSouth Dakota air permitsSouth Dakota Department of Agriculture and Natural Resources (DANR). South Dakota DANR's Air Quality Program issues minor source operating permits (ARSD 74:36:04), Title V (Part 70) operating permits, general permits for portable and stationary sources (asphalt plants, rock crushers, concrete plants, grain elevators), and PSD pre-construction permits (ARSD 74:36:09, adopting 40 CFR 52.21). South Dakota is in attainment, so nonattainment NSR (ARSD 74:36:10) does not currently apply. The Rapid City area has PM10 Natural Events Action Plan requirements, including general permits for construction and continuous activities on state property. EPA Region 8 is the permitting authority in Indian Country.
- StateOhio air permitsOhio Environmental Protection Agency (Ohio EPA). Ohio EPA DAPC issues air permits through its Central Office and district offices plus eight local air agencies that serve as Ohio EPA's representatives for their counties. Non-Title V facilities get a Permit-to-Install and Operate (PTIO); Title V facilities get a Permit-to-Install (PTI) for construction plus a Title V operating permit (OAC 3745-77). Lower tiers include permanent and discretionary exemptions (OAC 3745-31-03), the de minimis exemption (OAC 3745-15-05), permits-by-rule (OAC 3745-31-30), and general permits (OAC 3745-31-29), including oil and gas well-site and natural gas compressor station general permits. Best Available Technology (BAT) applies to new sources. Major sources go through attainment-area review (PSD, OAC 3745-31-10 to -20) or nonattainment review (OAC 3745-31-21 to -27).
- StateCalifornia air permitsCalifornia Air Resources Board (CARB) with 35 local air districts. California's 35 local air districts are the primary agencies that review and issue stationary source air permits. CARB plays an oversight role and generally does not issue preconstruction or operating permits (Cal. Health & Safety Code §§ 39620, 41500). Districts issue an Authority to Construct (ATC) before building or modifying equipment and a Permit to Operate (PTO) once ATC requirements are met; they also run New Source Review and EPA-approved Title V programs. CARB directly regulates oil and gas methane emissions through a statewide regulation enforced with districts.
- StateUtah air permitsUtah Department of Environmental Quality (DEQ). Utah DAQ requires an Approval Order (AO) before starting construction or operation of emitting equipment, obtained by filing a Notice of Intent under R307-401 (New Source Review section). Small sources may be exempt (R307-401-9), and permits by rule are available for listed emission units (R307-431) and source categories (R307-432). Oil and gas sources on state-jurisdiction lands register once under R307-505 and follow the R307-500 series oil and gas rules. Major sources need nonattainment/maintenance area review (R307-403) or PSD (R307-405) and a Title V operating permit (R307-415). EPA Region 8 is the permitting authority in Indian Country.
- StateColorado air permitsColorado Department of Public Health and Environment (CDPHE). Colorado uses a two-step system: sources report emissions on an Air Pollutant Emission Notice (APEN) above APEN thresholds, and need a construction permit above facility-wide permit thresholds (Regulation 3, Parts A and B). Lower thresholds apply for VOC and NOx in the Denver Metro/North Front Range ozone nonattainment area. General permits cover common oil and gas equipment, engines, and land development. Major sources need a Title V operating permit (Regulation 3, Part C) and PSD/NNSR review (Regulation 3, Part D). Since June 30, 2026, APENs and construction permit applications must be filed through the online submission tool, and applications require an Environmental Justice Summary.
- StateDelaware air permitsDelaware Department of Natural Resources and Environmental Control (DNREC). In Delaware, any equipment that emits or controls air contaminants needs DNREC approval before construction or operation under 7 DE Admin. Code 1102, unless exempt or eligible for registration. Sources are classified as natural minor, synthetic minor, or major. Major sources are subject to NSR/PSD (Regulation 1125) and Title V (Regulation 1130). Major source thresholds for VOC and NOx are lower in New Castle and Kent counties than in Sussex County.
- StateNew Mexico air permitsNew Mexico Environment Department (NMED). NMED's Air Quality Bureau regulates stationary sources statewide except Albuquerque/Bernalillo County. Depending on emissions, a source may need no permit, a Notice of Intent (20.2.73 NMAC), a minor source construction permit or general construction permit (20.2.72 NMAC), a PSD permit (20.2.74 NMAC), a nonattainment permit (20.2.79 NMAC), and/or a Title V operating permit (20.2.70 NMAC). Most applications use the Universal Application Form and the AQB ePermitting Portal.
- StateNorth Carolina air permitsNorth Carolina Department of Environmental Quality (NC DEQ). NC DAQ issues air permits statewide, with local programs in Forsyth County, Mecklenburg County, and Asheville/Buncombe County. Options by size: permit exemption for very small facilities (15A NCAC 02Q .0102), registration for low-emitting facilities (02D .0202), general permits for listed source types, Small and Synthetic Minor permits (02Q .0300, .0315), Title V permits for major sources (02Q .0500), and PSD/nonattainment NSR for major new sources and modifications. Non-Title V permits run eight years; Title V permits five years. A zoning consistency determination is needed for a complete application.
- StateSouth Carolina air permitsSouth Carolina Department of Environmental Services (SCDES). SCDES (formerly SC DHEC's environmental programs) issues air construction permits before construction, alteration, or addition of a stationary source, and operating permits afterward, under S.C. Regulation 61-62.1 Section II. Lower tiers include construction permit exemptions (61-62.1 Section II(B) and the BAQ exemptions list), registration permits, and general permits (general construction, general state operating, and general conditional major operating permits) for sectors such as concrete plants, asphalt plants, nonmetallic mineral processing, and fuel combustion. Conditional major (synthetic minor) permits take limits to avoid PSD (61-62.1 Section II.E) and Title V (Section II.G). Title V is under Regulation 61-62.70. Non-Title V applications must be filed through ePermitting (paper not accepted after February 1, 2025). There are no local air agencies.
- StateFlorida air permitsFlorida Department of Environmental Protection (DEP). Florida DEP requires an air construction permit before building or modifying non-exempt emissions units, and an air operation permit to operate. Many small sources qualify for categorical, conditional, or generic exemptions (Rule 62-210.300(3), F.A.C.) or for one of the air general permits (Rule 62-210.310). Minor construction permits are processed by DEP districts or approved local programs; PSD, nonattainment NSR, and power plant permits are processed by the Division. Operation permits are state-only (natural or synthetic minor), federally enforceable state operation permits (FESOP), or Title V (Chapter 62-213).
