SUMMIT COUNTY — Sloppy operations, maintenance and record-keeping have cost a Wyoming refinery $378,000 in fines, according to the EPA, which this week announced a Clean Air Act settlement with the Sinclair Wyoming Refining Company.

Along with the fine, Sinclair will update operating procedures, perform required training to workers, improve maintenance of equipment and perform integrity tests on pressure vessels and piping that will reduce the possibility of an accidental release of hazardous chemicals at its refinery in Sinclair, Wyoming.

Hazardous substances of concern used at the Sinclair refinery include large quantities of propane, butane, and flammable hydrocarbon mixtures. Under the Clean Air Act, facilities that utilize hazardous and flammable substances above specified thresholds must develop and submit a risk management plan to assist with emergency preparedness, chemical release prevention, and minimization of releases that occur.

In June 2010, an EPA inspection found that the facility had not adequately implemented those regulations.

“Sinclair has had several accidents and releases of hazardous substances over the past several years that relate to process equipment,” said Mike Gaydosh, director of EPA’s enforcement program in Denver. “This settlement will help ensure the company is operating in accordance with industry standards to protect the environment as well as residents of nearby communities.”

Among other things, the inspection showed that Sinclair failed to replace rusted out pipes and didn’t test and replace pressure relief valves at the facility. The company also was far behind on required inspections and maintenance procedures, according to the EPA.

The consent decree was lodged in U.S. District Court and is subject to a 30-day comment period and final approval by the court. A copy of the consent decree is available on the Department of Justice website at: http://www.usdoj.gov/enrd/Consent_Decrees.html.
