The California Air Resources Board has fined a diesel parts manufacturer $1 million for selling aftermarket equipment that modified emission control systems.
According to a CARB news release, investigators for the air quality agency discovered H&S Performance LLC was selling diesel engine parts and modifications that hadn’t been exempted from California’s emissions control system anti-tampering laws. State law prohibits the sale, delivery and installation of parts that modify emissions control systems of vehicles unless equipment manufacturers have demonstrated the devices don’t reduce effectiveness of emissions control systems.
“An important part of California’s clean air efforts is maintaining the integrity of the emissions control systems on the millions of vehicles that travel our highways each day,” CARB Enforcement Chief Jim Ryden said, according to the release.
“We take it very seriously when any manufacturer fails to follow the required procedure to prove that its performance products do not reduce the capabilities of the original emissions control system.”
CARB said aftermarket performance parts manufacturers are allowed to sell parts in California after a comprehensive engineering evaluation is performed to ensure the parts don’t create more emissions.
The news release stated that $750,000 of the fine will be paid to the California Air Pollution Control Fund. The remaining $250,000 will be sent to the School Bus and Diesel Emission Reduction Supplemental Environmental Project, which funds cleaner vehicles and equipment in California.
“This settlement only covers the illegal marketing and sales of these devices in the California market,” CARB said in the release.
