H.R. 1346
Sponsor: Adrian Smith (R-NE)
This bill amends the Clean Air Act to address the limitations on Reid Vapor Pressure (a measure of gasoline's volatility) that are placed on gasoline during the summer ozone season. Specifically, the bill applies the waiver for Reid Vapor Pressure requirements that is applicable to gasoline blended with 10% ethanol (E10) to gasoline blended with up to 15% ethanol (E15). This change allows gasoline that is blended with 10% to 15% ethanol to be sold year-round.
