Sinclair Oil Pays $3.8 Million Penalty to Resolve Violations of 2008 Consent Decree

August 22, 2012


The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice settled a dispute with Sinclair Oil Corporation about alleged violations of air pollution. The limits were established in a 2008 consent decree at refineries in Casper and Sinclair, Wyo. The violations included exceeding nitrogen oxides emissions limits and failing to comply with requirements to operate and maintain a flare gas recovery system that resulted in excess emissions of sulfur dioxide.

“EPA is committed to ensuring that companies comply with environmental requirements that protect people’s health,” said Cynthia Giles, assistant administrator for EPA’s Office of Enforcement and Compliance Assurance.

Sinclair will pay penalties totaling nearly $4,000,000 and spend approximately $10.5 million on additional pollution control equipment to resolve their case. Sinclair must reduce emissions of nitrogen oxides by 24 tons per year, sulfur dioxide by 385 tons per year, and particulate matter by 59 tons per year. Sinclair will also complete a project to provide road paving at its Casper refinery that will reduce particulate matter emissions.

The settlement is subject to a 30-day public comment period and final court approval.
