EPA Preparing to Release NPRM on Heavy-Duty Vehicles

March 11, 2022 11:30 AM | Jennifer Bruce, CMP (Administrator)

The Environmental Protection Agency (EPA) is preparing to release a Notice of Proposed Rulemaking (NPRM) to reduce air pollution from highway heavy-duty vehicles and engines, including ozone, particulate matter, and greenhouse gases. This proposal would change the heavy-duty emission control program to further reduce the air quality impacts of heavy-duty engines across a range of operating conditions and over a longer period of the operational life of heavy-duty engines. In addition, this proposal would make targeted updates to the existing Heavy-Duty Greenhouse Gas Emissions Phase 2 program, proposing that further GHG reductions in the Model Year 2027 timeframe are appropriate considering lead time, costs, and other factors. The notice also includes limited amendments to the regulations that implement air pollutant emission standards for other sectors (e.g., light-duty vehicles, marine diesel engines, locomotives, various types of nonroad engines, vehicles, and equipment).

As soon as this NPRM is published in the Federal Register a link will be sent to you.
