Petrol Refiners' Settlement Expected to Reduce Harmful Emissions by 7,000 Tons Per Year

Frontier Refining and Frontier El Dorado Refining have agreed to pay a civil penalty of $1.23 million and spend approximately $127 million in pollution control upgrades for alleged Clean Air Act violations at its refineries in Cheyenne, Wyo., and El Dorado, Kan. Wyoming Refining Co. has agreed to pay a civil penalty of $150,000 and spend approximately $14 million in similar upgrades for alleged violations at its Newcastle, Wyo. refinery. Harmful emissions are expected to drop by 7,000 tons per year.

The three refineries are required to install advanced control technologies that, when fully implemented, will reduce annual emissions of sulfur dioxide by approximately 3,775 tons, nitrogen oxide by approximately 2,100 tons and other pollutants by approximately 1,200 tons. The refineries have a combined production capacity of approximately 168,000 barrels per day.

In addition, each refinery will upgrade leak-detection and repair practices to reduce harmful emissions from pumps and valves, implement programs to minimize the number and severity of flaring events and adopt new strategies for ensuring continued compliance with benzene waste requirements under the Clean Air Act. Flaring, the process by which byproduct-gas from the refining process is burned off, can cause respiratory problems and exacerbate asthma.

As part of the settlement, Frontier agreed to implement environmentally beneficial projects valued at more than $1.3 million, including the installation of dome covers on refinery storage tanks to reduce volatile organic compound (VOC) emissions. VOCs are a prime ingredient in the formation of smog.

The settlement requires Frontier to correct deficiencies in the refinery’s risk management program that were identified during a 2006 EPA inspection. These deficiencies included overdue inspections and tests of storage vessels containing toxic and flammable substances.

Under the Clean Air Act, facilities that handle large amounts of chemicals are required to develop a risk management program, which assesses the hazards associated with dangerous chemicals. The program must include an accident prevention program and an emergency response plan to deal with accidental releases.

The agreements are the latest in a series of comprehensive, company-wide settlements under an EPA initiative to reduce air pollution from refineries nationwide. With Tuesday's settlements, 99 refineries operating in 29 states, or 88 percent of the nation’s refining capacity, are required to reduce emissions under company-wide enforcement agreements.

The state of Wyoming joined the federal government in the agreement with WRC. Both the states of Wyoming and Kansas joined the federal government in the agreement with Frontier.

The consent decrees, lodged on Tuesday in the U.S. District Courts in Kansas and Wyoming, are subject to a 30-day public comment period and approval by the federal court.
