SPOKANE — Three Inland Northwest companies selling parts for heavy-duty diesel trucks have agreed to pay a combined $180,000 in fines to the Environmental Protection Agency, whose investigators say they sold devices designed to bypass air quality standards.
The EPA announced the actions in a news release Thursday, identifying Diesel Power Products, of Spokane Valley, and Alligator Diesel Performance and Deviant Race Parts, of Hayden, Idaho, as the companies settling cases.
The companies were the target of a nationwide crackdown by regulators on sellers and manufacturers of “defeat devices,” which are aftermarket products that alter the function of features that have become standard on trucks since the 1970s to reduce the amount of nitrogen oxides and particulate matter in exhaust.
Enforcement records published by the EPA found that the three companies sold more than 70,000 parts during a period of January 2016 to May 2018 that could be considered in violation of federal laws controlling pollution. Those parts included electronic tuners that can override vehicle computers, which stop operation if emissions controls aren’t working. They also included exhaust pipes that don’t include features intended to reduce emissions and engine parts that alter an exhaust recirculation system reducing temperature and nitrogen oxide emissions in diesel trucks.
