UPHE Sues Diesel Brothers

UPHE wins summary judgement against Diesel Brothers

Diesel Brothers charged with vehicle tampering that increases harmful air pollution along Utah’s Wasatch Front. They  received an $850,000 penalty and a permanent ban on defeating pollution controls as a consequence of violating the Clean Air Act hundreds of times. 

Utah Physicians for a Healthy Environment (UPHE) sued a conglomerate of Utah companies and individuals for deliberately and systematically destroying pollution control equipment on diesel trucks in violation of the Clean Air Act.

Known on social media as the “Diesel Brothers,” the group’s sprawling complex in Woods Cross is famous for building “bad ass” trucks that belch black clouds of smoke – called “rolling coal” – in downtown Salt Lake City and other urban areas.

When diesel trucks made in the last ten years are stripped of their pollution control equipment, their engines emit more than thirty times the air pollution compared to untampered, stock vehicles.  This 3,000 percent increase in pollution, per vehicle, is similar to that caused by Volkswagen’s illegal tampering of its diesel cars.

“Pollution controls on diesel vehicles are mandated by law,” said Dr. Howie Garber, UPHE Board Member.  “These pollution controls are also necessary to prevent the many acute and chronic diseases that are caused by and exacerbated by air pollution. Unfortunately, Diesel Brothers are turning these trucks into disease-generating machines.”

“As physicians we see the broad range of health consequences from air pollution–sudden death, heart attacks, strokes, lung disease, cancer, and birth defects,” explained Dr. Brian Moench, UPHE President.

Diesel exhaust is one of the most toxic types of pollution there is.  It is, in fact, dangerous and deadly.  This company’s removal and deactivation of vehicle pollution control equipment represents a callous disregard for the harm they are doing to the entire community.  It is also deeply offensive to all the law abiding vehicle owners who make a good faith effort to abide by our pollution laws.”

UPHE’s complaint states that deliberately removing pollution controls on diesel trucks can cause a ten- to over 30-fold increase in emissions of health-damaging particulate matter and oxides of nitrogen from each vehicle, in violation of federal law.

The Clean Air Act authorizes citizens, just as it does EPA, to seek civil penalties for pollution violations.  Ideally these should be directed towards local air pollution prevention, similar to the VW case.  Any penalties would go to the federal Treasury, not to UPHE.
