WOODS CROSS — An environmental watchdog group has filed suit against Davis County-based TV personalities who rose to fame by modifying trucks that spew smoke and perform stunts.
Utah Physicians for a Healthy Environment has accused frontmen for the Discovery Channel show “Diesel Brothers” of violating both the federal Clean Air Act and the Utah State Implementation Plan. “Heavy D” David W. Sparks, “Diesel Dave” David Kiley, “Redbeard” Joshua Stuart and “The Muscle” Keaton Hoskins gained a following by modifying vehicles and posting about it on their DieselSellerz.com website, YouTube channel and social media pages.
Some of the group’s posts showed illegally modified vehicles “coal rolling” a Prius and trucks blowing illegal levels of pollution, the lawsuit claims. A few of the posts in question have been deleted from the group’s social media accounts.
The lawsuit accuses the group of selling illegally modified vehicles and emission control defeat devices online. It also claims they created an online marketplace to buy and sell those products through DieselSellerz.com.
Discovery Channel aired a reality show about the “Diesel Brothers” last year. The lawsuit was filed less than a week before the show’s second season starts and amid inversion season on the Wasatch Front. The Diesel Brother’s DieselSellerz website is headquartered at 1955 S. 1800 West in Woods Cross.
A lawsuit filed Jan. 10 in U.S. District Court claims the Diesel Brothers’ activities have exceed federal emissions standards by 30 times or more.
The suit also claims that from November 2011 to the present, Diesel Brothers have “repeatedly violated” Utah’s State Implementation Plan. The plan is designed to improve air quality in the state’s non-attainment areas, which include Davis County.
The suit seeks an injunction against the group to permanently stop tampering with emissions controls, driving tampered vehicles, and selling tampered vehicles and defeat devices.
The suit also orders the Diesel Brothers to pay a civil penalty of $37,500 to $93,750 per day for each tampered vehicle they’ve owned, operated or built in Utah. It orders another $100,000 for air quality mitigation projects.
Utah Physicians for a Healthy Environment first notified the Diesel Brothers of their intent to sue last July.
Representatives with DieselSellerz in Woods Cross declined to comment on the lawsuit. As of Tuesday afternoon, attorneys for Utah Physicians for a Healthy Environment and the Discovery Channel had not responded to requests for comment.
