On March 18, 2019, (EPA) announced a public hearing to be held for the proposed rule: “Modifications to Fuel Registrations to Provide Flexibility for E15: Modifications to RFS RIN Market Regulations.” 84 Fed. Reg. 9734. The proposed rule would implement regulatory changes allowing E15 to take advantage of a Renewal Fuels Standard (RFS) program waiver. Currently, the 1-psi Raid Vapor Pressure (RVP) waiver only applies to ten percent ethanol (E10) during the summer months. The proposed rule also includes an interpretative definition of E15 gasoline as “substantially similar” to the fuel used to certify Tier 3 motor vehicles. Lastly, EPA is also proposing changes to some RFS compliance system elements that would improve renewable identification number market functioning and prevent market manipulation. The public hearing will take place in Ypsilanti, MI, on March 29, 2019. The proposed rule was published in the Federal Register on March 21, 2019. 84 Fed. Reg. 10584.
