Approval of States' Requests To Relax the Federal Reid Vapor Pressure Volatility Standard in Florida, and the Raleigh-Durham-Chapel Hill and Greensboro/Winston-Salem/High Point Areas in North Carolina

The Environmental Protection Agency (EPA) is taking direct final action to approve requests from Florida and North Carolina for the EPA to relax the Reid Vapor Pressure (RVP) Standard applicable to gasoline introduced into commerce from June 1 to September 15 of each year in six counties in Florida, and in counties in the Raleigh-Durham- Chapel Hill Area (also referred to as the "Triangle Area") and the Greensboro/Winston-Salem/High Point Area (also referred to as the "Triad Area") in North Carolina. Specifically, the EPA is approving amendments to the regulations to change the RVP standard for six counties in Florida, and for the counties in the Triangle and Triad Areas from 7.8 pounds per square inch (psi) to 9.0 psi for gasoline. The EPA has determined that these changes to the federal RVP regulation are consistent with the applicable provisions of the Clean Air Act (CAA or Act). This action is being taken without prior proposal because the EPA believes that this final rulemaking is noncontroversial, for the reasons set forth in this preamble, and due to the limited scope of this action.
