Partial Withdrawal and Final Rule for Nonroad Technical Amendments
EPA is adopting amendments to the technical hardship provisions under the Transition Program for Equipment Manufacturers related to the Tier 4 standards for nonroad diesel engines, and to the replacement engine exemption generally applicable to new nonroad engines. These provisions may have minor impacts on the costs and emission reductions of the underlying regulatory programs amended in this action, though in most cases these are simple technical amendments. For those provisions that may have a minor impact on the costs or benefits of the amended regulatory program, any potential impacts would be small and we have not attempted to quantify the potential changes.
