EPA expands sale of E15 gasoline, modifies RIN compliance system

Changes allow for year-round sale of E15

Posted June 4, 2019

EPA announced it has finalized regulatory changes allowing for year-round sale of E15 (gasoline blended with up to 15 percent ethanol). The changes adopt the 1-psi Reid Vapor Pressure (RVP) waiver that currently applies to E10 in the summer months.

EPA regulates the vapor pressure of gasoline sold at retail stations during the summer ozone season (June 1 to September 15) to reduce evaporative emissions from gasoline that contribute to ground-level ozone and diminish the effects of ozone-related health problems.

EPA also is finalizing regulatory changes to modify certain elements of the renewable identification number (RIN) compliance system of the Renewable Fuel Standard (RFS) program. The reforms include public disclosure if a party’s RIN holdings exceed certain thresholds and additional data collections to improve EPA market monitoring capability. EPA says these reforms will provide the information required to decide whether further action is warranted to ensure stability in the RIN market.
