Utah Air Permits

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.

Oil & Gas

Utah (Uinta Basin) regulates oil and gas through a registration/permit-by-rule system and equipment-specific rules in the R307-500 series: general provisions (501), pneumatic controllers (502), flares (503), tank truck loading (504), registration (505), storage vessels (506), dehydrators (507), VOC control devices (508), LDAR (509), natural gas engines (510), and associated gas flaring (511). Most oil and gas sources are minor or exempt small sources. Sources in Indian Country (much of the Uinta Basin) are permitted by EPA Region 8.

  • Oil and Gas Registration (Permit by Rule)

    Registration / Notice

    One-time registration with DAQ for oil and gas sources on lands under state jurisdiction. Filing fee: $2,000 controlled site, $1,000 uncontrolled site. Registrants with uncontrolled actual emissions above one ton per year of any single pollutant file emission inventories (annual or triennial under R307-150) using the PBR workbook.
