The stars of Discovery Channel's Diesel Brothers television show are being ordered to pay $851,451 for their role in producing and selling modified diesel pickups that wreaked environmental havoc in the state of Utah. David "Heavy D" Sparks, Joshua Stuart, Keaton Hoskins, and Dave Kiley—a.k.a. "Diesel Dave"—were the targets of a case that reached a federal judge after being initiated by Utah Physicians for a Healthy Environment. The judge ruled that the defendants must pay the amount to the United States government and Davis County with additional restitution potentially on the way.

The Salt Lake Tribune reports that U.S. District Court Judge Robert Shelby announced in his ruling Friday that the plaintiffs may also submit their attorney fees to be paid by Sparks and Co. Per Cole Cannon, a lawyer for the Diesel Brothers, the opposing party claimed $1.2 million in fees when speaking with the judge. Shelby confirmed that the defendants must pay $761,451 to the U.S. government with the remaining $90,000 going to Davis County. This comes less than a year after Shelby found those involved with the television program guilty of violating the Clean Air Act and Utah state law by stripping diesel pickups of their legally required emissions equipment. This includes components such as diesel particulate filters (DPF) and exhaust gas recirculation (EGR) systems, both of which have been the focus of multiple regulation enforcement operations by the Environmental Protection Agency. Court documents show that none of the fines can be avoided or dismissed in bankruptcy, according to KSL. The Diesel Brothers reality show chronicles the adventures of Heavy D, Diesel Dave and their crew as they work on various larger-than-life vehicle projects. Whether it be modifying customers' trucks or building their own to give away in sales-related sweepstakes, essentially everything is tied to making pickups bigger, louder, and more outrageous than the rest. The Discovery program is more or less the result of a diesel-related retail empire that Sparks and the others have created with customization culture at its core. Prior to their television days, the crew made a name for themselves through YouTube and social media with all sorts of antics, often tied to or directly through "rolling coal" on other cars and, sometimes, each other.

Cannon explained to the Tribune that his clients wished for more of the court-ordered payout to benefit the state of Utah. His explanation as to why, though, was more than questionable. “My clients have always been committed to restoring air quality in Utah,” he said. In direct contradiction to Cannon's statement, the Utah Physicians for a Healthy Environment found the pickups built and modified by the Diesel Brothers to be grossly over-polluting. The plaintiffs actually purchased a truck from Sparks Motors and promptly sent it to Denver for testing, in which the results showed it emitted 36 times more pollution and 21 times more particulate matter than if it was equipped with proper emissions systems.
