ARB Settles with Cummins Engine Co. for $1.1 million
Sacramento - The California Air Resources Board (ARB) announced today that Cummins Engine Company, manufacturer
of heavy duty diesel engines, has paid $1,092,500 for allegedly violating its 1998 settlement agreement with ARB
to perform clean air projects and certify its engines to reduce smog-forming emissions such as NOx (oxides of nitrogen).
"We are very pleased that Cummins is taking steps to reduce excess emissions from the heavy duty engines in
question, and that they are cooperating by instituting recalls and retiring emissions credits," said ARB Executive
Officer Catherine Witherspoon.
Among the violations of the 1998 settlement agreement ARB alleged, Cummins obtained state certification for 11,600
heavy duty engines equipped with emission control systems that did not meet emissions requirements, omitted 26,347
engines from eligibility for the Low NOx Rebuild (Chip Reflash) program, and failed to complete work on and to
submit reports for agreed upon emission reduction projects in a timely manner. ARB investigated these violations
jointly with U.S. EPA, which entered parallel agreements to settle these violations.
In addition to paying over $ 1 million in penalties, as part of the latest settlement agreements Cummins is required
to recall the 11,600 engines nationwide that did not meet state emissions requirements. In addition, Cummins will
retire emissions credits from further use. (Emissions credits are a market mechanism, created to help industries
meet various emissions standards; they are bought, sold and traded by refineries, power plants, and other emissions
sources.) Cummins is reimbursing 979 NOx tons to the U.S. and to California through ARB to compensate for the
excess tons generated by the prohibited emission control devices, and 1042 tons of NOx for its non-compliance with
the earlier settlement agreement.
All monies are being paid to the California Air Pollution Control Fund (APCF). The APCF was established to mitigate
various sources of pollution through education and the advancement and use of cleaner technology. This fund uses
compliance settlement fees to support various pollution-related research projects and related programs. The Legislature
controls the use of the APCF through the annual Budget Act.
