General Air Permits

General Permits Public Meetings


The Colorado Air Pollution Control Division is developing a facility-wide general permit for upstream oil and gas facilities in Colorado. We have scheduled two upcoming public listening sessions to invite your feedback. Join us to learn more, ask questions, and share your thoughts on the drafting of the permit and the development of the Air Dispersion Modeling study used to support the permit.

Wednesday, June 7

Wednesday, June 21

Our proposed analysis is online for review. You can also provide written public comment

General permits and associated forms are available here.
  • General permits offer a streamlined approach, they're available for land development activities and certain oil and gas operations.
  • Sources that can meet the criteria of emissions limitations and other operating conditions may qualify for a general permit. On the Air Pollutant Emission Notice, you may choose to apply for a general permit.
  • When the general permit isn't applicable or doesn't meet the unique needs of a facility, we issue an individual permit through the traditional construction permit process.

​​We no longer accept blank Air Pollutant Emission Notices. We charge additional fees for applications submitted without the necessary information. Use only forms supplied by the Air Pollution Control Division.  For more information, see reporting your air emissions and applying for air permits step-by-step.



Effective September 7, 2022 the Division has updated its registration process for General Permits GP01, GP02, GP05, GP06, GP07, GP08, GP09, GP10 and GP11 to align with recent updates to the construction permitting process. Sources newly seeking coverage under a General Permit need to submit a demonstration of compliance with the National Ambient Air Quality Standards (NAAQS) with the General Permit registration. Consistent with the updates, the Division has created a Permit Application/Registration checklist (Form APCD-100) for General Permit registrations. For more information on the modeling determination process and permit modeling, please visit the Permit Modeling Unit webpage.

Effective August 1, 2023, in order for a General Permit registration to be considered complete, sources with any quantifiable amount of new emissions of NOx, SO2, PM, or CO, must fill out APCD Form-114, submit to the Permit Modeling Unit (PMU), provide PMU's determination with the General Permit registration, and obtain a completeness determination from the Division. If an applicant does not receive notification of a completeness determination from the Division within 60-days of the Division's receipt of the registration, the registration will be deemed complete.* Form instructions are provided here. More information on when APCD Form-114 is required, is provided here.

If you have questions about this new process, you can contact oil and gas permit unit supervisors, Bradley Eades, bradley.eades@state.co.us, or Stephanie Spector, stephanie.spector@state.co.us. If you have specific questions about APCD Form-114, you can contact Miriam Hacker, permit modeling unit supervisor, at miriam.hacker@state.co.us.

*See "General Permit Registration Approval Process" terms within each general permit, which requires a complete registration before commencing construction.
