Cummins Settles California Diesel Emissions Case at $46M

The California Air Resources Board (CARB) and California Department of Justice (DOJ) today announced a  settlement with engine manufacturer Cummins Inc. The settlement resolves DOJ and CARB’s claims for violations of California engine emissions control and certification requirements. Cummins made undisclosed changes to ~120,000 engines in California after CARB had certified the engines for sale. In addition, ~2000 Cummins engines had undisclosed auxiliary emission control devices that altered the emissions control system and resulted in emissions that exceeded regulatory limits. This case signals CARB’s improving vehicle testing skills and use of technology to catch and correct air quality violations.

“At the California Department of Justice, we are committed to vigorously enforcing environmental laws that protect Californians and our environment,” said California Attorney General Rob Bonta. “Today’s settlement makes clear that the DOJ will relentlessly continue its efforts to hold accountable those who seek to profit at the expense of people’s health and safety.”

Of the $46 million in payments required under the settlement, approximately $42 million will be paid to CARB: $32 million for penalties and ~$9.8 million for mitigation of the full amount of excess nitrogen oxide emissions created by the non-compliant engines. 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. The California Attorney General’s Office also entered into a settlement with Cummins, subject to court approval, for $4 million for unfair business practices and public nuisance claims and secured injunctive relief prohibiting Cummins from engaging in similar violations in the future.

“CARB’s rigorous, state-of-the-art enforcement efforts ensure that air quality laws are followed. And if issues are uncovered, collaboration and action from manufacturers such as Cummins make it possible to quickly implement needed fixes to provide the public health and air quality benefits that Californians need and deserve,” said Dr. Steven Cliff, CARB’s Executive Officer.
