Cummins Inc. Settles For $455,525
In April 2026, the California Air Resources Board (CARB) reached a settlement with Cummins Inc. (Cummins), with its principal location in Columbus, Indiana, in the amount of $455,525 for violating CARB’s Small Off-Road Engines Regulation (SORE Regulation), as codified in the California Code of Regulations, title 13, sections 2400‑2409.
Cummins voluntarily disclosed to CARB that it had submitted inaccurate information about the auxiliary emission control devices (AECD) described in many of its 2011 through 2024 model year SORE certification applications. These AECDs are important components in SOREs that help maintain proper emission control during many different phases of an engine’s operation. Failure to provide complete and accurate AECD information when applying for emissions certification to CARB is a violation of the SORE Regulation pursuant to Code of Federal Regulations, title 40, sections 1054.201(b), 1054.255(c)(2), and sections 1065.2(a) and (c) of the “California Exhaust Emission Standards and Test Procedures For New 2013 And Later Small Off-Road Engines,” as incorporated by reference in the California Code of Regulations, title 13, sections 2403(d).
CARB’s subsequent analysis of the full AECD documentation showed that the original violations were minor in nature, and ultimately had no detrimental emission impacts on Cummins’ certified SOREs. Notwithstanding, the company proactively instituted a new internal review system to reduce similar AECD issues from occurring in the future.
The full civil penalty amount will be deposited into CARB’s Air Pollution Control Fund, which provides funding for projects and research to improve California’s air quality. Cummins was cooperative with CARB throughout the agency’s investigation, and corrected all incomplete certification applications as required.
