Cummins Inc. Settles For $46 Million
In March 2024, the California Air Resources Board (CARB) reached a mutual settlement with Cummins Inc. (Cummins) for alleged violations of California’s certification and test procedure requirements. Specifically, Cummins made undisclosed changes to approximately 120,000 engines in California after CARB had certified the engines for sale. In addition, roughly 2,000 Cummins engines had undisclosed auxiliary emission control devices that altered the emissions control system and resulted in emissions in excess of regulatory limits.
Cummins fully cooperated with CARB’s investigation. Of the $46 million under the settlement, approximately $42 million will be paid to CARB, of which approximately $32 million is for penalties, and approximately $9.8 million is for mitigation of the full amount of excess nitrogen oxide emissions created by the noncompliant engines. Cummins has the option of using half the amount of the penalties to invest in zero emission heavy duty infrastructure in California. The settlement monies will go to the Air Pollution Control Fund to support CARB’s mobile source emissions control program and other CARB activities related to the control of air pollution. Cummins will also pay $4 million to the California Attorney General’s Office for unfair business practices and public nuisance.
