Approval and Promulgation of Implementation Plans; State of Missouri

Короткий зміст

EPA proposes to approve the State Implementation Plan (SIP) revision concerning the Missouri Control of Gasoline Reid Vapor Pressure (RVP) rule submitted by the Missouri Department or Natural Resources (MDNR). This action would approve amendments to State controls on the summertime Reid Vapor Pressure (RVP) of gasoline distributed in Clay, Jackson, and Platte Counties. This amendment changed the RVP limit from 7.2 pounds per square inch (psi) to 7.0 psi, and from 8.2 psi to 8.0 psi for gasoline containing at least 9.0 percent by volume but not more than 10.0 percent by volume ethanol. This is a part of the state's plan to maintain its clean air quality.
