The EPA and the U.S. Department of Justice have announced a $425 million settlement with subsidiaries of Tesoro Corp., and Par Hawaii Refining that resolves alleged Clean Air Act violations and protects public health by reducing air pollution at six refineries. Under the settlement, the two companies will spend about $403 million to install and operate pollution control equipment, and Tesoro will spend about $12 million to fund environmental projects in local communities previously impacted by pollution. Tesoro will also pay a $10.45 million civil penalty.

“The advanced technologies Tesoro and Par are required to implement are the future for protecting people from toxic air emissions,” said Cynthia Giles, EPA assistant administrator for enforcement and compliance assurance. "this settlement puts new enforcement ideas to work that will dramatically cut pollution and protect communities."

The settlement includes provisions that resolves ongoing clean air act violations at refineries in Kenai, Alaska; Martinez, California; Kapolei, Hawaii; Mandan, North Dakota; Salt Lake City, Utah; and Anacortes, Washington.  of the $10.45 million civil penalty that Tesoro will pay, the United States will receive $8,050,000, and co-plaintiffs including the states of Alaska and Aawaii, and the Northwest Clean Air Agency will share $2.4 million.
