Caterpillar To Pay EPA $2.55 Million Due To Clean Air Act Violations

The Environmental Protection Agency and Department of Justice yesterday announced that they had reached a settlement with Caterpillar, the popular construction equipment manufacturer, over Clean Air Act violations that the company allegedly committed. Caterpillar allegedly failed to report its emission controls and meet engine-labeling requirements. As a result of the settlement, Caterpillar will pay a $2.55 million fine, and both recall noncompliant engines and reduce excess emissions.

According to the EPA, Caterpillar allegedly shipped over 590,000 highway and off-road diesel engines without the correct emissions controls required by the Clean Air Act. The emission controls that the Clean Air Act requires are called after-treatment devices. After-treatment devices control the engine's exhaust in its exhaust system, like catalytic converters and diesel particulate filters, as well as the proper fuel map settings and ECU calibration. The EPA say's that, "Caterpillar allegedly shipped over 590,000 engines to vehicle assemblers without the correct [after-treatment devices] and with improperly configured fuel injector and map settings." In some cases, those engines were then put into trucks that released excess NOx into the environment.
"This settlement demonstrates our commitment to enforcing the Clean Air Act," said assistant attorney general for the Environment and Natural Resources Division of the Department of Justice, Ignacia S. Moreno. "Caterpillar will pay a substantial civil penalty for shipping engines that did not comply with these Clean Air Act requirements."
The state of California too is looking to get into the action. The California Air Resources Board, better known as CARB, is also settling with Caterpillar for engines that lacked proper after-treatment devices. California is looking to get a $510,000 settlement from Caterpillar.
