Title of document
Modifications to Fuel Regulations To Provide Flexibility for E15; Modifications to RFS RIN Market Regulations (47 page(s), in English)

The Environmental Protection Agency (EPA) is proposing 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.
