CASPER, Wyo. (AP) — A Wyoming oil refining company is expected to pay $1.6 million in penalties for what the government says were emissions violations.

The Casper Star-Tribune reports that Sinclair Wyoming Refining Company in Sinclair agreed to the payment as part of a settlement with federal and state agencies.

The Environmental Protection Agency, the U.S. Department of Justice and the Wyoming Department of Environmental Quality announced the agreement Thursday.

The company also agreed to install additional pollution controls as a result of the agreement.

The settlement resolves claims that the refinery 125 miles (201 kilometers) southwest of Casper violated state and federal air emissions limits and monitoring requirements, including guidelines in a 2008 settlement.

A Sinclair representative says the company would not be able to comment Thursday.
