Approval of Tennessee's Request To Relax the Federal Reid Vapor Pressure Gasoline Volatility Standard for Davidson, Rutherford, Sumner, Williamson, and Wilson Counties; and Minor Technical Corrections for Federal Reid Vapor Pressure Gasoline Volatility Standards in Other Areas

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 in Davidson, Rutherford, Sumner, Williamson, and Wilson Counties (the Middle Tennessee Area). Specifically, EPA is approving amendments to the regulations to allow the gasoline RVP standard for the five counties 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). Finally, EPA is making several minor technical corrections to address clerical errors made in prior rulemakings that relaxed the gasoline RVP standard in other areas.
