US Environmental Protection Agency (EPA) Administrator Andrew Wheeler signed the final action that would remove the key regulatory barrier to using gasoline blended with up to 15% ethanol (E15) during the summer driving season and reform the renewable identification number (RIN) compliance system under the Renewable Fuel Standard (RFS) program to increase transparency and deter price manipulation. (Earlier post.)
With the action, EPA is finalizing regulatory changes to apply the 1-psi Reid Vapor Pressure (RVP) waiver that currently applies to E10 during the summer months so that it applies to E15 as well. This removes a significant barrier to wider sales of E15 in the summer months, thus expanding the market for ethanol in transportation fuel.
EPA is also finalizing regulatory changes to reform certain elements of the RIN compliance system of the RFS program to increase transparency and deter price manipulation in the RIN market. The reforms include requirements for public disclosure if a party’s RIN holdings exceed certain thresholds and additional data collections to improve EPA market monitoring capability.
