EPA Comment Deadline: Modifications to Fuel Regulations To Provide Flexibility for E15

The Environmental Protection Agency (EPA) is seeking public comments on its proposed regulatory changes to allow gasoline blended with up to 15 percent ethanol to take advantage of the 1-pound per square inch (psi) Reid Vapor Pressure (RVP) waiver that currently applies to E10 during the summer months. EPA is also proposing an interpretive rulemaking which defines gasoline blended with up to 15 percent ethanol as “substantially similar” to the fuel used to certify Tier 3 motor vehicles. Finally, EPA is proposing regulatory changes to modify certain elements of the Renewable Fuel Standard (RFS) compliance system, in order to improve functioning of the renewable identification number (RIN) market and prevent market manipulation.


The objectives of this action are twofold. First, this rulemaking will take steps intended to create parity in the way the RVP of both E10 and E15 fuels is treated under EPA regulations. Second, this action proposes reforms to RIN regulations intended to increase transparency and deter potential manipulative and other anti-competitive behaviors in the RIN market.

Members of the public may submit comments via mail, fax, or at Regulations.gov. More information is available this Federal Register notice and at the EPA website.
