## Abstract

Because EPA received adverse comments, we are withdrawing the direct final rule extending the MOVES Regional Grace Period, published on October 13, 2011. The direct final rule would have extended the grace period to March 2013, before the Motor Vehicle Emission Simulator model (currently MOVES2010a) is required for regional emissions analyses for transportation conformity determinations ("regional conformity analyses").
