Suncor Refinery in Commerce City Faces Emissions Issues Following Shutdown
Suncor Energy's Commerce City refinery experienced a shutdown due to electrical issues, leading to increased emissions. The Colorado Department of Public Health and Environment is monitoring air quality following reported pollution levels exceeding permitted limits.

An electrical issue at Suncor Energy's refinery in Commerce City triggered a shutdown, resulting in emissions exceeding permitted levels. The Colorado Department of Public Health and Environment (CDPHE) confirmed that higher carbon monoxide and hydrogen sulfide levels were detected from Plant 2, contributing to increased sulfur dioxide emissions.
Community alerts indicated that smoke may persist for several days, although air monitoring has shown low pollution levels for key air toxics. In 2024, Suncor faced over $10.5 million in fines for repeated violations, underscoring ongoing regulatory scrutiny. Continued monitoring by CDPHE may impact operational protocols at the facility.
