The Environmental Protection Agency (EPA) issued a decision to grant two requests for waivers of redemption regarding four California Air Resource Board (CARB) regulations related to California’s heavy-duty vehicle and engine emission standards.
“Under the Clean Air Act, California has longstanding authority to address pollution from cars and trucks. Today’s announcement allows the state to take additional steps in reducing their transportation emissions through these new regulatory actions,” said EPA Administrator Michael S. Regan.
The waivers address the following programs: the 2018 Heavy-duty 2018 Warranty Amendments, which extend the emissions warranty periods for 2022 and subsequent model year on-road heavy-duty diesel engines and for 2022 and subsequent model year diesel vehicles with a gross vehicle weight rating exceeding 14,000 pounds powered by such engines; and the Advanced Clean Trucks Regulation, which requires that manufacturers produce and sell more medium- and heavy-duty zero-emission vehicles and near-zero emission vehicles.
