Sinclair Oil to Pay $3.8 Million Penalty and Install Pollution Controls at Wyoming Refineries to Resolve Violations of 2008 Consent Decree

Sinclair Oil to Pay $3.8 Million Penalty and Install Pollution Controls at Wyoming Refineries to Resolve Violations of 2008 Consent Decree

WASHINGTON – The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice announced a settlement with two subsidiaries of Sinclair Oil Corporation to resolve alleged violations of air pollution limits established in a 2008 consent decree at refineries in Casper and Sinclair, Wyo. Sinclair Casper Refining Co. and Sinclair Wyoming Refining Co. will pay stipulated penalties totaling $3,844,000 and spend approximately $10.5 million on additional pollution control equipment and other projects to resolve the allegations. The settlement will require the Sinclair companies to reduce emissions of nitrogen oxides (NOx) by approximately 24 tons per year, sulfur dioxide (SO2) by approximately 385 tons per year, and particulate matter by approximately 59 tons per year.

“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. “This settlement holds Sinclair accountable for exceeding the emissions limits agreed to in a previous settlement for Clean Air Act violations and ensures that the people of Wyoming have cleaner, healthier air.”
“Parties who enter into consent decrees with the United States must adhere to their obligations, and failure to comply will result in further penalties,” said Ignacia S. Moreno, assistant attorney general for the Environment and Natural Resources Division of the Department of Justice. “This settlement requires Sinclair to pay a significant $3,844,000 penalty and provide additional emission reductions beyond those required in the original settlement.”

The alleged violations stem from Sinclair’s failure to meet the terms of the 2008 consent decree, including exceeding NOx emissions limits at the Casper and Sinclair, Wyoming refineries and failing to comply with requirements to operate and maintain a flare gas recovery system at the Sinclair Refinery, resulting in excess emissions of SO2. The problems will be addressed by installing and operating a selective catalytic reduction system to control NOx emissions and by upgrading the flare gas recovery system to meet SO2 emissions limits. Sinclair will also complete a project to provide road paving at its Casper refinery that will reduce particulate matter emissions by an additional 59 tons per year
and reduce fuel oil burning at the Casper refinery from the existing 188 tons per year limit to no more than 95 tons per year.

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

Visibility to Improve at 18 National Parks and Wilderness Areas

Visibility to Improve at 18 National Parks and Wilderness Areas
More than 11 million Arizona park visitors will benefit annually

SAN FRANCISCO – Today the U.S. Environmental Protection Agency is proposing to approve Arizona’s air quality plan to control sulfur dioxide and soot at three power plants in the state. EPA is also proposing additional pollution controls for nitrogen oxide at those plants. These actions will improve visibility and human health at 18 national parks and wilderness areas, including the Grand Canyon, Saguaro National Park and the Petrified Forest.
More than 11 million people visit national parks in Arizona every year. Yet for many visitors the spectacular vistas are veiled in haze, dulling the natural beauty. Ninety percent of the time, the Grand Canyon’s air is impaired by pollution. On average, pollution reduces the Grand Canyon's pristine natural visual range by more than 30 percent.


EPA is proposing to approve Arizona’s plan that controls emissions of sulfur dioxide and coarse particles from the older boilers at three power plants located in eastern Arizona. In addition, EPA is proposing a federal plan to limit nitrogen oxides (NOx) emissions at these same three plants. Specifically, the proposal is designed to cut NOx emissions by 7,800 tons per year at the Cholla Power Plant, 4,700 tons/year at the Apache Generating Station, and 4,500 tons/year at the Coronado Generating Station.


“Visitors to magnificent national parks in Arizona like the Grand Canyon are critical to the state’s economy,” said Jared Blumenfeld, EPA’s Regional Administrator for the Pacific Southwest. “This proposal will make scenic vistas clearer while cleaning the air that Arizonans breathe.”


Under the Clean Air Act, Congress set a long-term goal of restoring natural visibility conditions in numerous national parks and wilderness areas throughout the United States, known as Class 1 Areas. One of the strategies for achieving this goal is the use of Best Available Retrofit Technology at older power plants that cause or contribute to visibility impairment at Class I areas. The three power plants impact 18 of these areas.


In addition to reducing visibility, NOx reacts with other chemicals to form ozone and fine particles, both harmful to the public’s health. Ozone forms when NOx and volatile organic compounds react in the presence of heat and sunlight. Children, the elderly, people with lung diseases such as asthma, and people who work or exercise outside are at risk for adverse effects from ozone and particulate matter.  


EPA is soliciting public comments on the proposal through August 31, and will host a public workshop and hearing Tuesday July 31 in Phoenix. The deadline for final EPA action is November 15, 2012.
