H.R. 8519 — To require the Administrator of the Environmental Protection Agency to waive Reid Vapor Pressure requirements with respect to calendar year 2026, and for other purposes.

This section directs the EPA Administrator to waive Clean Air Act prohibitions on the sale, distribution, or introduction into commerce of gasoline with Reid Vapor Pressure exceeding the applicable standard (as defined in 40 CFR 80.27(a)(2), generally 9.0 psi) for the period May 1, 2026, through September 15, 2026. (As background, Reid Vapor Pressure standards limit gasoline volatility to reduce evaporative emissions that contribute to ground-level ozone formation.)
