Today the U.S. Environmental Protection Agency (EPA) settled with three interstate trucking companies after those companies violated the California Air Resources Board’s (CARB) Truck and Bus Regulation while operating in California. The three trucking companies will pay over $400,000 in penalties, and replace or retrofit existing equipment to meet Truck and Bus Regulation standards. One of the trucking companies was cited for using non-compliant Transportation Refrigeration Unit (TRU’s) equipment, whereas another company was cited for not having particulate matter filters installed on various equipment. The remaining trucking company was cited for not verifying that the carriers it had hired were Truck and Bus compliant. In the end, the last company not in compliance with the Truck and Bus rule will have to pay over $175,000 in civil penalties. This is a reminder that all trucking companies, whether owned and operated by your business or sub-contracted out, must meet Truck and Bus Regulation requirements. Specifically, a company that owns and operates heavy duty diesel trucks must have the current year’s TRUCRS compliance certificate.
