Harley Dealerships charged with motorcycle tampering that increases harmful air and noise pollution in Utah

Utah Physicians for a Healthy Environment Brings “Citizen Suit” Against Harley-Davidson Dealerships for Defeating Air and Noise Pollution Control Systems on Motorcycles

(July 18, 2022 – Salt Lake City) – Today Utah Physicians for a Healthy Environment (UPHE) brought a federal Clean Air Act and Noise Control Act enforcement action against four Harley-Davidson dealerships in Utah.  Brought under the citizen suit provisions of both laws, UPHE alleges that the dealerships have been selling ear-splitting, high-polluting motorcycles for years.   

The dealerships are Harley-Davidson of Salt Lake City and South Valley Harley-Davidson Shop (Sandy), owned by Harley-Davidson of Salt Lake City, LLC, and Golden Spike Harley-Davidson (Riverdale) and Saddleback Harley-Davidson (Logan), owned by Northern Utah Power Sports, LLC.  Both limited liability companies are controlled by Joseph L. Timmons, Jr.  

UPHE’s complaint alleges the dealerships are violating the federal Clean Air Act and the federal Noise Control Act by removing pollution control devices in motorcycles, selling and installing emission and noise control defeat parts on new and used motorcycles, and owning and operating tampered motorcycles. 

“The excessive noise from motorcycles with aftermarket exhaust pipes startles me awake at night and drives me away from my garden during the day.  Their noise and air pollution are an invasion of my property and a threat to my personal health that is inconsiderate, harmful, and illegal,” said Dr. Kirtly Jones Board Member UPHE. “It is well established in the medical literature that motorcycles exceeding the noise limits can cause hearing damage, raise blood pressure, and increase the risk of heart disease and dementia.  It is also well known that exhaust pipes that remove catalytic converters add to the already polluted, unhealthy air of the Wasatch Front.”  

UPHE’s complaint states that the dealerships’ tampered motorcycles are more than twice as loud, and emit more than twice the air pollution than allowed by federal law. 

The excess hydrocarbons and nitrogen oxides emitted by these tampered motorcycles contribute to the unhealthy levels of ozone and particulate matter along the Wasatch Front.  The excess noise discharged by these motorcycles impairs the health and disturbs the peace of UPHE members. 

“Motorcycles stripped of their legally required pollution controls are a health hazard for two reasons–the excess pollution and the noise. We are too familiar with the health hazards of air pollution, but beyond being a nuisance and impairment of everyone else’s quality of life, the noise from these brazenly-tampered motorcycles is itself a health hazard,” said Dr. Brian Moench, President UPHE.

The groups’ complaint seeks an injunction against the dealerships to stop them from tampering with and removing noise and air pollution controls, to stop selling and installing defeat devices, and to pay a substantial penalty to the federal government.
