Suncor violated pollution permits for 900 hours during shutdown

Suncor Energy’s Commerce City Refinery Exceeds Pollution Limits During Shutdown

A recent study by environmental group 350 Colorado revealed that Suncor Energy’s oil refinery in Commerce City exceeded its permitted pollution limits for more than 900 cumulative hours during a three-month shutdown in late 2022 and early 2023. Colorado regulators are now investigating potential violations during this incident.

The study found that the refinery released excessive amounts of sulfur dioxide, hydrogen sulfide, carbon monoxide, and particulate matter during the shutdown period. This raised concerns among residents living near the refinery, who had hoped for cleaner air during the closure.

Despite efforts to reach Suncor officials for comments, no response was received. The shutdown was initiated in December 2022 after the hydrogen plant malfunctioned during an extreme deep freeze, leading to a series of operational issues.

Suncor, which supplies about 40% of the gasoline used in Colorado, faced scrutiny for its emissions during the shutdown. Refineries often release more pollutants during malfunctions and restarts, putting public health at risk.

The Colorado Department of Public Health and Environment has initiated an investigation into the refinery’s emissions violations during the shutdown. A compliance advisory was issued to Suncor, covering alleged violations from July 2022 to June 2023.

In addition to environmental concerns, the study also examined the impact of the shutdown on gas prices. Although prices spiked during the closure, the report argues that Suncor’s presence does not benefit Colorado drivers in terms of fuel costs.

As discussions continue regarding the refinery’s operations and environmental impact, it remains to be seen how the regulatory authorities will address the violations and ensure compliance with emission standards.
