On August 31, 2017, the U.S. Environmental Protection Agency (EPA) announced that requirements for reformulated gasoline and low volatility gasoline would be waived through September 15, 2017, for Alabama, Florida, Georgia, Kentucky, Maryland, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, Texas, Louisiana, and the District of Columbia. EPA exercised its emergency fuel waiver authority to help ensure an adequate supply of fuel throughout the South, Southeast, and the Mid-Atlantic in the wake of Hurricane Harvey. As required by law, EPA and the Department of Energy (DOE) evaluated the impacts of Hurricane Harvey on refineries in the Gulf Coast based on strict criteria provided in the Clean Air Act (CAA) and determined that granting a short-term waiver was consistent with the public interest. The CAA requires that waivers be limited as much as possible in terms of their geographic scope and duration. EPA and DOE continue to monitor the fuel supply situation and will act if it is determined that extreme and unusual supply circumstances exist in other areas.
