EPA Extends Emergency RVP Waiver allowing Summertime Sale of E15 Nationwide

On August 8, 2023, the Environmental Protection Agency (EPA) issued the fifth waiver extension this year allowing the sale of E15 blends nationwide during the summer driving season. This most current waiver is an extension of the previous RVP waiver issued by the EPA on July 8, 2023. The EPA can only issue RVP waivers for 20 days at a time under the Clean Air Act. The current RVP waiver extension begins on August 10, 2023, and lasts through August 29, 2023. The EPA plans to issue a string of RVP waiver extensions similar to last year that allow E15 to be used nationwide between June 1 and September 15. The RVP waiver temporarily exempts E15 from RVP volatility requirements that effectively block it from being sold during the summer driving season. To justify the emergency waiver, the EPA cites the same conditions that provided the foundation for a series of summerlong temporary RVP waivers last year. The EPA says that the fuel volatility waivers for E15 is in the public interest to address fuel supply shortages caused by the war in Ukraine. The EPA estimates that 2,700 retail gasoline stations nationwide currently sell E15.
