This bill mandates the Administrator of the Environmental Protection Agency (EPA) to waive specific Reid Vapor Pressure (RVP) requirements for gasoline. This waiver directly addresses the prohibition outlined in section 211(h) of the Clean Air Act, which typically restricts the sale and distribution of gasoline exceeding certain RVP limits. The required waiver will be effective for a distinct period, commencing on May 1, 2026 , and concluding on September 15, 2026 . During these months, it will allow for the sale, supply, and transport of gasoline that exceeds the established applicable RVP standard. The legislation clarifies that the "applicable standard" refers to the definition found in 40 CFR 80.27(a)(2) or any subsequent regulation.
