Caterpillar, Inc. Case Settles for $510,000

This settlement resolves Clean Air Act violations by Caterpillar for shipping over 590,000 on-road and off-road diesel engines without proper after treatment devices, submitting late emissions defect reports, selling engines without emissions labels, and selling engines with improperly configured fuel injector and map settings. This settlement reflects a joint effort between ARB, US EPA, and US DOJ. Caterpillar agreed to pay penalties totaling $2,550,000, including $510,000 to be paid to ARB. In addition to civil penalties, Caterpillar recalled and corrected noncompliant engines, and retired 17.6 tons of NOx + NMHC and .97 tons of PM emissions credits.
