The petitioners raised several concerns associated with the final RFS2 rule. Specifically, all four petitioners requested reconsideration on the issue of EPA's adoption of the "aggregate compliance approach" as part of implementing the requirements for renewable biomass for certain feedstocks grown in the U.S. In addition, one petitioner cited the exclusion of the global "rebound" effect in the lifecycle analysis used in determining compliance with the required greenhouse thresholds for various renewable fuels. On February 17, 2011, EPA issued its denial of these petitions because they fail to meet the criteria for reconsideration.
