Caterpillar is recalling more than 590,000 on-highway and off-road diesel engines and will pay a $2.55 million penalty to resolve alleged Clean Air Act violationsfor shipping the engines without the correct emissions controls. Caterpillar also allegedly failed to comply with emission control reporting and engine labeling requirements. The U.S. Environmental Protection Agency and the U.S. Department of Justice announced a settlement with Caterpillar, which continues to deny any wrongdoing, last week.
