EPA has expanded the Efficient Producer Petition Process (EP3) process to allow producers who are registered to generate cellulosic biofuel (D-3) RINs for ethanol produced from corn kernel fiber to use the EP3 process to also generate RINs for non-grandfathered corn starch or grain sorghum ethanol. Prior to this update, the EP3 approval process could not be used for facilities who wished to generate both D-6 RINs from corn starch ethanol and D-3 RINs from ethanol created from corn kernel fiber. Producers who wish to use this new approach under the EP3 must first submit a new pathway petition following the instructions posted on EPA’s website. These modifications do not impact facilities that have already been approved or registered for an EP pathway.
