Approval of Tennessee's Petition To Relax the Federal Reid Vapor Pressure Volatility Standard From 7.8 psi to 9.0 psi

الملخص

In this document EPA is approving as a direct final rule Tennessee's petition to relax the Reid Vapor Pressure Standard (RVP) applicable to gasoline introduced into commerce from June 1 to September 15 in the former Knox County ozone nonattainment area from 7.8 pounds per square inches (psi) to 9.0 psi. Knox County, Tennessee has met the requirements for redesignation from nonattainment to attainment status contained in section 107(d)(3)(E) of the Clean Air Act. Tennessee's petition is based on evidence that the Knox County area does not need the 7.8 psi standard to maintain ozone attainment. EPA believes that further imposition of the 7.8 psi volatility standard would impose needless costs in light of Tennessee's attainment of the National Ambient Air Quality standard. This action is being taken without prior proposal because EPA believes that this final rulemaking is noncontroversial, for the reasons discussed above and due to the limited scope of this rulemaking.
