The California Air Resources Board (CARB or Board) will conduct a public hearing at the date and time noted below to consider approving proposed amendments to the On-Road HeavyDuty Engine and Vehicle Omnibus Regulation, the Low Carbon Fuel Standard (LCFS), and to propose permanently adopting the Emergency Vehicle Emissions Regulations that CARB previously noticed as an emergency rulemaking on September 15, 2025.
CARB is proposing these Omnibus amendments, LCFS amendments, and permanent adoption of its Emergency Vehicle Emissions Regulations together as one rulemaking for administrative efficiency, but the Omnibus and Associated Amendments, LCFS Amendments, and Emergency Vehicle Emissions Regulations are three separate regulatory items proposed for approval.
