Air permit self-certification


Self-Certification information should be submitted electronically to cdphe_apcd_selfcertification@state.co.us

The final step of the air-permitting process to finalize the permit is to submit the Final Approval and Self-Certification packet. Within 180 days after receiving the Initial Approval permit, you must certify compliance with the permit requirements to receive a Final Approval permit. The Final Approval and Self-Certification packet must be submitted within 180 days of commencement of operations, or the permit may be revoked.
After we issue a construction permit, you must file a Notice of Start-up (NOS) for the associated equipment and complete the self-certification process. Do not submit the Notice of Start-up(s) through the self-certification email. These should be submitted separately by downloading and submitting the electronic form. If you are having issues submitting the NOS form, contact Amber Stowell

You must submit the Notice of Start-up no more than 15 days after the equipment begins to operate. The form must include the specific equipment details that weren't provided with the permit application. This includes the make, model and serial-number information of the emissions source and emissions-control equipment.


Important notice: The Air Pollution Control Division is launching a new online tool for Notice of Start-ups submissions. The division anticipates the new tool will be available in late July or August 2024. The current form submission process will remain available through December 31, 2024. Starting January 1, 2025, the new online tool must be used to submit Notice of Start-ups.

You can now create an account in the new online system. Select the “Create an account” icon on the division’s electronic submission web page.

The new online submission process includes:

  • An electronic receipt for data.
  • Data storage in a cloud environment.
  • Accessible information with data visualization tools.
