The CDPHE Air Pollution Control Division developed an online submission tool for permits and reports. The division is now accepting several air forms through the online portal, including:
- Modeling Requirements Determination Form APCD-114.
- Environmental justice summary.
- Notice of Startup.
- Relocation Notice.
- Land Development Air Pollutant Emissions Notice (APEN).
- Modeling determination.
- APEN for Crematory operations.

- APEN for Well Production Facility (GP09/10).
The division will continue to expand the online submission tool with more electronic forms in 2025 and beyond. During that time, the division anticipates launching the following forms using this new online submission process:
- APEN for Dry Cleaning Operations.
- APEN for Mining Operations.
- APEN for Condensate Storage Tanks.
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.
