Approval of Tennessee's Request To Relax the Federal Reid Vapor Pressure (RVP) Gasoline Volatility Standard for Shelby County (Memphis)

概要

The Environmental Protection Agency (EPA) is taking final action to approve a request from the state of Tennessee for EPA to relax the Reid Vapor Pressure (RVP) standard applicable to gasoline introduced into commerce from June 1 to September 15 of each year (summertime ozone season) in Shelby County, Tennessee (the Memphis Area). Specifically, EPA is approving amendments to the regulations to allow the gasoline RVP standard for Shelby County to rise from 7.8 pounds per square inch (psi) to 9.0 psi. EPA has determined that this change to the federal RVP regulation is consistent with the applicable provisions of the Clean Air Act (CAA).
