Update: The Air Pollution Control Division launched an online submission tool for permits and reports, including the Notice of Startup.
As of January 2025, all Notice of Startup forms must be submitted using the online submission tool. Visit the division’s electronic submission web page to learn more and create an account.
The new online submission tool is part of the division’s multi-year data modernization project. It involves updating, enhancing, and streamlining a variety of processes including permitting. The data modernization work is ongoing, and the division anticipates completing most of the transformation by 2027.
Overview
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 of receiving the Initial Approval permit, you must certify compliance with the permit requirements to receive a Final Approval permit. You must submit the Final Approval and Self-Certification packet within 180 days of commencement of operations, or the permit may be revoked.
- Guidance for Self-Certification.
- Self-Certification information should be submitted electronically to cdphe_apcd_selfcertification@state.co.us.
- Form APCD-400: Self-Certification form.
- Form APCD-401: Self-Certification Timeline Table.
- Operators who have facility-wide permits covering multiple emissions points that have phased construction and different startup dates must submit the Self-Certification Timeline Table each time a new emissions point is certified.
- Construction permit Final Approval process.
- Operating and maintenance plan requirements (non-oil and gas sources).
- Opacity and stack testing firms.
After a construction permit is issued, a Notice of Startup must be filed for the associated equipment and the Self-Certification process must be completed. The Notice of Startup form should be submitted using the online submission tool. The Notice of Startup must be submitted no more than 15 days after the equipment begins to operate. The form must include the specific equipment details not provided within the permit application. This includes the make, model, and serial number of the emissions source and emissions-control equipment.
