This ICR is a revision to burden associated with emission certification requirements affecting converters of on-highway heavy-duty engines. EPA has finalized regulations to simplify and lessen the burden for manufacturers seeking approval to introduce into US commerce light-duty vehicles, light-duty trucks, medium-duty passenger vehicles, and heavy-duty vehicles and engines that have been converted for use of fuels that the original models were not designed for, such as from gasoline to liquid propane gas (LPG) or compressed natural gas (CNG). This ICR covers the heavy-duty portion of the proposal.
US Code:
42 USC 7521
Name of Law: Clean Air Act, Title II
The burden described in this ICR adds to the existing inventory for this ICR series. This increase is due to the expected increase in respondents as well as increased capital start-up costs.
