Suncor Refinery Under Scrutiny in Colorado | Denver News

Colorado regulators are launching a major investigation into the Suncor refinery in Commerce City after it emerged as the state’s top emitter of volatile organic compounds — a key ingredient in harmful ground-level ozone. The facility also leads in releasing sulfur dioxide, carbon monoxide, and nitrogen oxides, making it one of the nation’s most polluting refineries. Residents near the site are sounding alarms over health risks and frequent emissions, while state officials vow to push for faster, stronger air quality rules — including giving regulators more enforcement power and improving public alerts during malfunctions. Suncor says it’s committed to upgrades and community support, with opportunities to weigh in on any new regulations.
