The Environmental Protection Agency (EPA) exercised its authority under the Clean Air Act to temporarily waive clean gasoline requirements for gasoline sold and distributed in Louisiana, Mississippi, Alabama, Georgia, Florida, Tennessee, South Carolina and North Carolina, the US agency said Wednesday.
The EPA, which said the waiver had been requested by governors in those states, cited a disruption in fuel supply from Gulf-area refineries following Hurricane Isaac
EPA Administrator Lisa P. Jackson determined that extreme and unusual supply circumstances exist, which could result in a temporary shortage of gasoline compliant with federal regulations.
The federal waiver will help ensure an adequate supply of gasoline in the impacted states until normal supply to the region can be restored, the EPA says.
The waiver applies to the use of low Reid Vapor Pressure (RVP) summer gasoline for the remainder of the high-ozone period, which ends on Sept 15.
Due to a number of continuing refinery outages caused by Hurricane Isaac, and the slower-than-expected-pace of restarts of other Gulf-area refineries, EPA determined that there would not be an adequate supply of summertime gasoline for these states through Sept. 15.
The waiver allows available supplies of higher RVP winter gasoline to be used prior to the end of the high-ozone period, in order to prevent a gasoline supply shortfall in these states.
States bordering on this area are projected to have sufficient supplies of compliant summertime fuel through the end of the high ozone period in two weeks, and no shortages are expected to develop.
However, EPA said it will continue to actively monitor fuel supplies in these areas, and will act if needed to prevent a shortfall.
Last week, the EPA granted a 10-day waiver to Louisiana alone as Isaac made landfall.
