The Environmental Protection Agency and the US Department of Energy on Tuesday extended the summertime waiver for the sales of E15 blended gasoline through June 29.
The waiver regarding the requirements in 40 CFR 1090.215 allows for the production and distribution of a single national gasoline pool with 9% to 15% ethanol content at a common Reid Vapor Pressure standard of 10 pounds per square inch, according to the EPA announcement.
In the same waiver letter, EPA is reissuing a waiver for federal enforcement of state-level "boutique" fuel requirements for gasoline under 40 CFR 1090.215. Both waivers share a 20-day effective window from June 10, 2026, to June 29, 2026.
The EPA noted that states that have adopted fuel standards under consumer protection and/or air quality statutes may need to waive those provisions in State code to enable implementation of the Federal waiver in the States.
In May, the EPA extended a waiver allowing the nationwide summer sales of E15, effective until June 9.
