## Abstract

EPA is finalizing amendments to certain of the Renewable Fuel Standard program regulations that were published on March 26, 2010, and that took effect on July 1, 2010 ("the RFS2 regulations"). Following publication of the RFS2 regulations, promulgated in response to the requirements of the Energy Independence and Security Act of 2007, EPA discovered some technical errors and areas within the final RFS2 regulations that could benefit from clarification or modification. In a direct final rule and parallel notice of proposed rulemaking published on May 10, 2010, EPA included language to amend the regulations to make the appropriate corrections, clarifications, and modifications. However, EPA received adverse comment on a few provisions in the direct final rule and, on June 30, 2010, withdrew those provisions prior to their effective date of July 1, 2010. In today's action, EPA is addressing the comments received on the portions of the direct final rule that were withdrawn and is taking final action regarding the withdrawn provisions based on consideration of the comments received.
