On January 12, 2018, the California Air Resources Board (CARB) will conduct a public workshop regarding CARB staff’s potential amendments to California’s heavy-duty vehicle (HDV) emission warranty requirements. According to CARB staff, the workshop will focus on potential changes to Title 13, California Code of Regulations, Section 2036, and specifically, amendments to required emission warranty periods and manufacturer-scheduled maintenance. CARB staff will present the workshop as a webcast (available here).

Background

Under United States law, the federal Clean Air Act (CAA) generally preempts individual states from adopting their own emission standards. The Act, however, grants California the ability to seek authorization to set the state’s own more stringent standards. See 42 U.S.C. § 7543(b). Manufacturers generally prefer a single national standard and, as a practical matter, often follow CARB standards when they are stricter.
