EPA Weighs Dropping DEF-Derate Rules for Diesel Trucks

The EPA is considering eliminating limp-mode/derate restrictions triggered by low Diesel Exhaust Fluid in diesel trucks and is requesting data from the top manufacturers to assess warranty claims, failure rates, and repairs for certain model years, with a 30-day deadline. This follows a broader shift toward deregulation under Administrator Lee Zeldin, who previously extended the window before derates took full effect. If derates may no longer be required for compliance, diesel pickups could run at higher performance without frequent DEF refills.

Congress Overturns Biden's Truck Emissions Rules

The House voted to revoke a Biden administration emissions regulation for heavy-duty trucks, which was already overturned by the Senate in April. The White House has said President Biden will veto the decision, and a two-thirds vote in both chambers would be required to override the veto. Republicans argue that the rule is overly burdensome and will hurt the trucking industry, while Democrats say it is necessary to limit pollution and improve air quality. The final tally was 221 to 203, mostly along party lines.

Senate and White House clash over truck emissions regulation.

The Senate voted to revoke a Biden administration emissions regulation for heavy-duty trucks, with Republicans arguing that the existing standards are already stringent and the new approach will hurt the trucking industry and have negative ripple effects through the economy. The final rule, adopted by the Environmental Protection Agency in December, sets new emission standards that are significantly more stringent and cover a wider range of heavy-duty engine operating conditions compared to today's standards. The Republican-led House is expected to pass the measure as well, although it's unlikely either chamber would be able to override an expected veto by President Joe Biden.
