EPA Issues Emergency Fuel Waiver for E15 Sales


LEARN MORE: Explaining Unleaded 88 Gasoline - aka E15

EPA takes action to provide consumers relief at the pump by helping ensure an adequate fuel supply-Why Not E40?

WASHINGTON (April 28, 2023) The U.S. Environmental Protection Agency today is issuing an emergency fuel waiver to allow E15, gasoline blended with 15% ethanol & to be sold during the summer driving season.

This action will provide Americans with relief at the pump from ongoing market supply issues by increasing fuel supply and offering consumers more choices from fuel supply crises by reducing our reliance on imported fossil fuels, building U.S. energy independence, and supporting American agriculture and manufacturing. Current estimates indicate that on average, E15 is about 25 cents a gallon cheaper than E10.

Allowing E15 sales during the summer driving season will not only help increase fuel supply, but support American farmers, strengthen U.S. energy security, and provide relief to drivers across the country.

The Clean Air Act allows the EPA Administrator, in consultation with DOE, to temporarily waive certain fuel requirements to address shortages. Administrator Regan determined that extreme and unusual fuel supply circumstances exist and has granted a temporary waiver to help ensure that an adequate supply of gasoline is available. As required by law, EPA and DOE evaluated the situation and determined that granting the waiver was in the public interest. F'in DUH!

Currently, in roughly two-thirds of the country, E15 cannot be sold from terminals starting on May 1 and at retail stations starting on June 1. EPA is providing relief by extending the 1-psi Reid Vapor Pressure (RVP) waiver that currently applies to E10 gasoline to E15, which will enable E15 sales throughout the summer driving season in these areas, if necessary. This action only extends the 1-psi waiver to E15 in parts of the country where it already exists for E10. E15 can already be sold year-round in parts of the country that have a Reformulated Gasoline (RFG) program.

Because the RVP of E10 and E15 gasoline used by consumers will be the same (both will be 1 psi higher than otherwise required by EPA or state regulations) EPA does not expect any impact on air quality from this limited action. EPA's 30 year old research has shown no significant impact on evaporative emissions when the 1-psi waiver is extended to E15. With no significant impacts on emissions from cars and trucks, we expect consumers can continue to use E15 without concern that its use in the summer will impact air quality. (So what has been the problem ???)

EPA's emergency fuel waiver will go into effect on May 1 when terminal operators would otherwise no longer be able to sell E15 in the affected regions of the country and will last through May 20 which is the statutory maximum of 20 days. EPA will continue to monitor the supply with industry and federal partners, and the Agency expects to issue new waivers effectively extending the emergency fuel waiver until such time as the extreme and unusual fuel supply circumstances are no longer present.
