Fact Sheet: Increasing Fuel Supply in the Aftermath of Hurricanes Gustav and Ike
http://www.whitehouse.gov/news/releases/2008/09/20080915-7.html
The EPA has waived certain fuel requirements in order to make it easier to use the supplies we have domestically and increase flexibility in what we can import. This waives requirements for gasoline sold or distributed in Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, part of Ohio, South Carolina, Tennessee, Texas, and Virginia.
But you also have to have the State authorities ALSO waive STATE regulations.
