Cheyenne, WY – Two companies have agreed to improve air pollution controls at two refineries in Wyoming and one in Kansas.
Federal officials say the settlements announced yesterday will bring refineries in Cheyenne and Newcastle in Wyoming and in El Dorado in Kansas into compliance with the Clean Air Act.
Houston-based Frontier Oil Corp. will install about 127 million dollars worth of pollution control improvements at its refineries in Cheyenne and El Dorado. It also will pay a civil penalty of just over 1 million dollars.
Wyoming Refining Co. will have to make about 14 million dollars worth of improvements to its Newcastle plant and pay a 150-thousand dollar civil penalty.
