EPA Won’t Delay 2027 NOx Rule, Plans Changes
The U.S. Environmental Protection Agency is moving forward with the 2027 timeline for its heavy-duty NOx rule—currently set to take effect with the 2027 model year—but says changes are in store.
The American Trucking Associations (ATA), National Tank Truck Carriers, Truckload Carriers Association, and 49 state trucking associations in August penned a letter to EPA, asking the regulator to push implementation to 2031, citing “substantial compliance costs and operational burdens at a time when the trucking industry is already contending with historically difficult market conditions.”
Administrator Lee Zeldin in March announced that the EPA was reevaluating the Biden-era 2022 Heavy-Duty Engine and Vehicle rule that regulates oxides of nitrogen (NOx) and other emissions beginning with Model Year 2027.
