The Justice Department, Environmental Protection Agency (EPA), California Air Resources Board (CARB) and the California Attorney General’s office today released the details of a proposed settlement with diesel engine maker Cummins Inc. for alleged violations of the Clean Air Act and California law. Beyond agreeing to pay a $1.675 billion civil penalty – the largest ever assessed in a Clean Air Act case – Cummins has agreed to spend more than $325 million to remedy the violations, which included the use of software “defeat devices” that circumvented emissions testing and certification requirements.
