Because EPA and NHTSA, on behalf of the Department of Transportation, received adverse comment on certain elements of the Heavy-Duty Engine and Vehicle and Nonroad Technical Amendments direct final rule published on June 17, 2013, we are withdrawing those elements of the direct final rule and republishing the affected sections without those elements.
