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.
