EL DORADO, Kan. (AP) — The owners of an oil refining plant in El Dorado have agreed to pay a $4 million fine for violating federal clean air regulations, federal and state officials said Thursday.
HollyFrontier also will make improvements to reduce emissions and improve risk management practices, the Environmental Protection Agency and Kansas health officials said.
The Dallas-based company exceeded emission limits and did not comply with chemical accident prevention and regulatory safety requirements at the El Dorado plant, which is one of the largest refineries in the Midwest.
