Two oil companies have agreed to spend $141 million improving pollution controls at Kansas and Wyoming refineries, federal officials said Tuesday.
Frontier Refining and Frontier Refining El Dorado agreed to spend $127 million upgrading its facilities in Cheyenne, Wyoming, and El Dorado, Kansas, the Justice Department said in a release. The company also agreed to a $1.23 million civil penalty.
Wyoming Refining Co. agreed to pay a $150,000 civil penalty and to spend $14 million on upgrading pollution controls at its refinery in Newcastle, Wyoming.
The agreement requires the companies to install equipment that will bring the refineries into compliance with the Clean Air Act by removing sulfur dioxide, nitrogen oxide and other pollutants. They must also reduce the number of flaring incidents to cut benzene emissions.
Wyoming joined in both settlements and Kansas in the settlement with Frontier.
