The California Air Resources Board (CARB) invites transit agencies and transit bus manufacturers to participate in a webinar on the requirements and process of requesting an exemption under the Heavy-Duty Engine and Vehicle Omnibus Regulation (Omnibus Regulation). Transit agencies can request an exemption for 2022 and subsequent models of diesel-fueled medium or heavy heavy-duty engines used in urban buses if they meet the requirements of title 13, CCR, section 1956.8(a)(2)(F) in the Omnibus Regulation.
