Sinclair Wyoming Refining v. EPA, No. 16-9532 (10th Cir. 2017)Annotate this Case
In an amendment to the Clean Air Act (CAA), Congress directed the EPA to operate a Renewable Fuel Standards Program (the RFS Program) to increase oil refineries’ use of renewable fuels. But for small refineries that would suffer a “disproportionate economic hardship” in complying with the RFS Program, the statute required the EPA to grant exemptions on a case-by-case basis. Petitioner Sinclair Wyoming Refining Company owned and operated two refineries in Wyoming: one in Sinclair, and another in Casper. Both fell within the RFS Program’s definition of “small refinery” and were exempt from the RFS requirements until 2011. Those exemptions were extended until 2013 after the Department of Energy found Sinclair’s Wyoming refineries to be among the 13 of 59 small refineries that would continue to face “disproportionate economic hardship” if required to comply with the RFS Program. Sinclair then petitioned the EPA to extend their small-refinery exemptions. The EPA denied Sinclair’s petitions in two separate decisions, finding that both refineries appeared to be profitable enough to pay the cost of the RFS Program. Sinclair filed a timely petition for review with the Tenth Circuit court, which concluded the EPA exceeded its statutory authority under the CAA in interpreting the hardship exemption to require a threat to a refinery’s survival as an ongoing operation. Because the Court found the EPA exceeded its statutory authority, it vacated the EPA’s decisions and remanded to the EPA for further proceedings.
