EPA eyeing tighter truck emissions standards, 50-state uniformity

January 13, 2020

Just four years after U.S. Environmental Protection Agency finalized a sweeping set of regulations aimed at cutting emissions from heavy-duty trucks and tractors by 25% by 2027, EPA is eyeing new federal regulations to further tighten heavy-duty truck emissions and to create a so-called “50-state program” that harmonizes emissions standards nationally.

EPA Administrator Andrew Wheeler on Monday announced an advanced notice of proposed rulemaking (ANPRM), part of the Trump EPA’s Cleaner Trucks Initiative, that seeks input from the public and from trucking industry stakeholders about the next phase of regulations — chiefly, means to curb output of nitrogen oxide (NOx) and other air pollutants, Wheeler said.
