News Releases from Headquarters
WASHINGTON — The U.S. Environmental Protection Agency (EPA) announced today its intent to revisit provisions of the Phase 2 Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines following concerns raised by stakeholders in the trailer and glider industry.
“In light of the significant issues raised, the agency has decided to revisit the Phase 2 trailer and glider provisions,” said EPA Administrator Scott Pruitt. “We intend to initiate a rulemaking process that incorporates the latest technical data and is wholly consistent with our authority under the Clean Air Act.”
In September 2011, EPA and the National Highway Traffic Safety Administration (NHTSA) issued greenhouse gas (GHG) emissions and fuel efficiency standards for medium- and heavy-duty vehicles for model year 2014-2018 (“Phase 1”). These standards applied to newly manufactured engines, tractors, vocational vehicles, large pickups, and vans. In October 2016, EPA and NHTSA updated the standards for medium- and heavy-duty vehicles MY 2021-2027 (“Phase 2”), and regulated trailers and gliders – for the first time under the GHG program – with compliance deadlines beginning in 2018.
