This bill requires the Environmental Protection Agency to temporarily waive Reid Vapor Pressure requirements for gasoline during the summer months of 2026, specifically from May 1 through September 15. Reid Vapor Pressure is a measure of gasoline's volatility, and the EPA typically enforces strict limits on this measure to reduce air pollution and smog, particularly during warm weather when gasoline evaporates more readily. By waiving these requirements, the bill would allow gasoline with higher vapor pressure to be sold and distributed during this five-month period. The legislation appears designed to potentially address fuel supply or pricing issues, though the bill text does not specify the rationale. This waiver would affect fuel producers, refiners, and ultimately consumers who purchase gasoline during the specified timeframe.
