Murphy Oil USA has reportedly agreed to spend more than $142 million to install new and upgraded pollution-reduction equipment at two petroleum refineries in Wisconsin and Louisiana as part of a Clean Air Act settlement with the federal government. The settlement also requires the company to pay a $1.25 million civil penalty and spend an additional $1.5 million on a supplemental environmental project. In addition to installing new pollution controls at both refineries, the company will install covers on two wastewater tanks at the Louisiana refinery to control volatile organic compound (VOC) emissions and will install and operate an ambient air monitoring station in Meraux, Louisiana. The company has also agreed to implement several other projects, including noise abatement and dust-control measures. The proposed settlement will be lodged in the U.S. District Court for the Western District of Wisconsin and is subject to a 30-day public comment period and court approval.
