Oil & Gas APENs

If your source (equipment) type is not listed below, please use the General Air Pollutant Emission Notice form. A guidance document is available for each form.

Your application will be rejected if it is filled out incorrectly, is missing information, missing required forms, or lacks payment for the filing fee. The Form APCD-100 and all applicable forms on that checklist are required with every application. The re-submittal will require a new filing fee. See our Application Rejection Frequently Asked Questions page for more information.

 

The following application types are exempted from the requirement to submit the Permit Application/Registration Checklist (Form APCD-100):

  • Air Pollutant Emission Notice (APEN) updates only (no changes to permit).
    • Renewal of 5-year APEN term.
    • Update to actual annual emissions, per AQCC Reg. 3, Part A, Section II.C.
  • APEN exempt sources.
  • Permit exempt sources.
  • Administrative permit amendments. (Including but not necessarily limited to name changes, changes in contact information, transfers of ownership, and typographical error corrections.)

General APEN Form APCD-200

The is a generic form used to obtain an air permit for a new source of air emissions, modify an existing air permit, request an administrative amendment to an existing air permit, or complete a routine (five-year) Air Pollutant Emission Notice renewal even when there is no change to an existing permit. When an equipment-specific Air Pollutant Emission Notice exists for a given source, it must be used instead of the General Air Pollutant Emission Notice. This form will NOT be accepted for reporting emissions from gas venting activities, including maintenance/blowdown events(use Gas Venting Form APCD-211), or hydrocarbon liquid loading operations (use Hydrocarbon Liquid Loading Operations Form APCD-208).
