Open Public Comment Period for Refinery Rulemaking

The division is seeking input while developing a proposal to reduce air quality impacts from refinery operations. 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.

Our team is particularly interested in feedback on the following questions:

How should the refinery reduce impacts from start up, shut down, and malfunction events?
How can the refinery minimize flaring?
How should information be communicated in a way that impacted communities need?
What other information would be meaningful for the refinery to provide to the community?
What are the community’s expectations when it comes to transparent, easy‑to‑understand data from the refinery?
How can technical and economic feasibility guide APCD’s choices around control technology recommendations?
What work practices and/or operational enhancement requirements should we be considering for this rulemaking?

Please share your thoughts with us in the comment box below. The public comment process will be open through Oct. 30, 2026.
