California Air Resources Board

The California Air Resources Board (CARB or Board) staff announces the release of the Concept Paper for a California Smog Check Contingency Measure for the State Implementation Plan (Smog Check Contingency Concept) and invites you to participate in a public workshop on Thursday, August 24, 2023, regarding development of the Smog Check Contingency Concept. At the workshop, we will discuss contingency measure requirements, the history of contingency measures for the State Implementation Plan (SIP) and provide an overview of the conceptual measure included in the Smog Check Contingency Concept that CARB staff is developing to fulfill federal Clean Air Act (Act) contingency measure requirements, alongside local air district measures, for certain National Ambient Air Quality Standards (standards). During the workshop, we encourage you to ask questions, engage in discussion with CARB staff, and provide feedback on the Smog Check Contingency Concept. Input received through this workshop will further inform CARB’s Smog Check Contingency Concept. CARB Staff plans to develop a proposal for a contingency measure utilizing California’s Smog Check program which it plans to bring before CARB’s Board for consideration in October 2023.
