CHEYENNE (WNE) — The Wyoming Attorney General’s Office is suing HollyFrontier Cheyenne Refining LLC for alleged environmental violations for a second time in two years.
The court case was filed July 2 in Laramie County District Court. It alleges the company is violating the Wyoming Environmental Quality Act, the Wyoming Air Quality Standards and Regulations and the U.S. Environmental Protection Agency’s Clean Air Act. An earlier lawsuit filed in February 2018 alleged similar violations and is still active.
HollyFrontier is a petroleum refining company that produces products such as gasoline, diesel fuel, jet fuel, specialty lubricant products and more, according to its website. It operates a refinery in south Cheyenne.
The AG’s office alleges the company exceeded the permitted limits for sulfur dioxide emissions, carbon monoxide pollution, nitrogen oxides and other pollutants.
A total of 17 environmental violation claims are included in the lawsuit. The state is asking for up to $10,000 in civil penalties for each day the company violated environmental regulations. It’s unclear from the lawsuit how many days the state alleges HollyFrontier to be in violation.
