Important update: As of October 2024, permit applicants are encouraged to use the division’s new electronic submission process to submit Modeling Requirements Determination Form APCD-114.

As a courtesy, the division will continue to accept the Modeling Requirements Determination Form APCD-114 (August 2024) as a PDF through Dec. 1, 2024. After that date, permittees must submit Form APCD-114 using the new electronic submission process above.

Overview 

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, visit the Permit Modeling Unit web page.

Effective August 1, 2023, in order for a General Permit registration to be considered complete, sources with any quantifiable amount of new emissions of nitrogen oxides (NOx), sulfur dioxide (SO2), particulate matter (PM), or carbon monoxide (CO), must fill out APCD Form-114. Submit the form to the Permit Modeling Unit, provide the Permit Modeling Unit 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.

If you have questions about this new process, you can contact the Oil and Gas Permit Unit at cdphe_apcd_airpermitcomments@state.co.us. 

If you have specific questions about APCD Form-114, you can contact the Permit Modeling Unit at cdphe_apcd_modelingdeterminations@state.co.us.

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 the 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.

 

On November 14, 2022 the Air Pollution Control Division issued revised versions of Operating and Maintenance Plan Templates for the following sources: Amine Sweetening Systems; Condensate, Crude Oil, and/or Produced Water Storage Tanks; Glycol Dehydration Systems, Hydrocarbon Liquid Loadout, Natural Gas-driven Pneumatic Pumps, Process Flares or Emergency Flares, Natural Gas Fired Reciprocating Internal Combustion Engines, and Separators.

The changes made to the Operating and Maintenance Plan Templates include, but are not limited to:

  • Consolidation of Forms APCD-304: Condensate Storage Tanks, APCD-307: Produced water storage tanks, and APCD-308: Crude oil storage tanks into a single template - APCD-304: Hydrocarbon liquid and/or Produced Water Storage Tanks.
  • Rendering obsolete and removing Form APCD-303: Fugitive component leaks.
