Air quality impacts from refinery operations

The Air Pollution Control Division is seeking input while developing a proposal to reduce air quality impacts from refinery operations. The division will hold a series of meetings in August and September to hear feedback, then develop a rule proposal by the end of this calendar year. The proposal will also be informed by findings from the Colorado Refinery Report the division published in May 2026, which compares data, requirements, and procedures for petroleum refineries nationwide and the Suncor refinery in Commerce City.

The division will hold all public meetings virtually over Zoom. The meetings will all cover the same information in a presentation and include opportunities for participants to share feedback. Translation and interpretation services will be provided.
