Sinclair to pay $3.8 million for pollution violations

HOUSTON (Reuters) - Sinclair Oil Corp will pay $3.8 million in penalties and spend $10.5 million for pollution-control equipment at its Wyoming refineries to settle allegations it exceeded air pollution limits, the U.S. Environmental Protection Agency said on Monday.

The violations stem from exceeding nitrogen oxide emissions limits at its 74,000-barrels-per-day (bpd) refinery in Sinclair and its 24,500-bpd plant in Evansville, near Casper.

The EPA also said the company failed to comply with requirements to operate and maintain a flare gas recovery system at the Sinclair refinery.

As part of the settlement, Sinclair agreed to install a selective catalytic reduction system to control nitrogen oxide emissions and upgrade the flare gas recovery system to meet sulfur dioxide emissions limits.

A Sinclair spokesman did not immediately respond to a request for comment.

Sinclair entered into a consent decree on pollution controls in 2008 with the EPA and the U.S. Justice Department. It agreed to pay a $2.45 million penalty and spend more than $72 million for new and upgraded pollution controls at the Wyoming refineries and a third refinery in Tulsa, Oklahoma, that Sinclair later sold.

The settlement announced Monday is subject to a 30-day period for public comments and final court approval.
