CHEYENNE, Wyo. -- The state of Wyoming has reached a nearly $5.4 million settlement with Sinclair Wyoming Refinery Co. for a spill that killed dozens of waterfowl last year.
The Wyoming Department of Environmental Quality announced the settlement Monday. The settlement includes an $850,000 state penalty and a $4.5 million commitment from Sinclair to improve equipment and minimize waste at the refinery, in Sinclair in south-central Wyoming.
Petroleum products spilled into a wastewater pond at the refinery in April 2010, killing at least 80 western grebes.
The fine is a big one for Wyoming's environmental regulatory agency and follows a $660,000 settlement between the state and Sinclair for spilling nearly 3 million gallons of gasoline blend at the refinery in 2009.
Salt Lake City-based Sinclair Oil Corp. operates two refineries, both in Wyoming.
