EPA and Colorado advance new rules to tighten air‑pollution controls

The Colorado Department of Public Health and Environment’s Air Pollution Control Division announced a series of virtual public meetings in August and September to gather feedback for a draft rule aimed at reducing emissions from the Suncor refinery in Commerce City. The proposed rule could require short‑term actions such as improved maintenance and long‑term projects like new equipment, with a final proposal expected by the end of 2026 and a rulemaking hearing slated for spring 2027.

Separately, the U.S. Environmental Protection Agency released a proposal that would let state agencies decide the timing and extent of public notification about air‑pollution permits for minor sources, such as diesel and gas engines. The rule would affect states like Texas, where the Texas Commission on Environmental Quality could determine public awareness of such permits. EPA officials say the change would not weaken existing air‑quality standards, though critics warn it could limit public participation, especially in lower‑income communities.
