Background
At its November 17, 2022, public hearing, the California Air Resources Board (CARB or Board) approved for adoption the proposed amendments to the In-Use Off-Road Diesel-Fueled Fleets Regulation (the current regulation) in sections 2449, 2449.1, and 2449.2, Title 13, California Code of Regulations (CCR). The amendments will reduce emissions by requiring that fleets of off-road diesel vehicles phase out operation of their oldest and highest emitting off road diesel vehicles, prohibiting the addition of high emitting vehicles to a fleet, and requiring the use of 99 percent or 100 percent renewable diesel in off-road vehicles. The proposed amendments also enhance enforcement of the current regulation by including several additional requirements on entities that enter into contracts with fleets subject to the current regulation. In addition, the proposed amendments introduce voluntary compliance flexibility options for fleets that adopt zero-emission technology.
The Board directed the Executive Officer to determine if additional conforming modifications to the proposed amendments were appropriate and, if so, to make any proposed modified regulatory language available for public comment, with any additional supporting documents and information, for a period of at least 15 days as required by Government Code section 11346.8. The Board further directed the Executive Officer to consider written comments submitted during the public review period and make any further modifications that are appropriate available for public comment for at least 15 days and present the proposed amendments to the Board for further consideration if warranted, or take final action to adopt the proposed amendments after addressing all appropriate modifications.
CARB has determined that additional modifications are appropriate for the proposed amendments and has developed proposed modifications (15-Day Changes). A description of the modifications made to the originally proposed regulatory language and documents and information added to the rulemaking record can be found in the 15-Day Notice.
Inquiries concerning the substance of the proposed regulatory action may be directed to the agency representative, Johanna Levine, Air Resources Supervisor I, Off-Road Implementation Section, at (916) 570-7888, or Angie Polanco, Air Resources Engineer, at (916) 292 8344.
The Notice, ISOR, and all subsequent regulatory documents are available on CARB's Rulemaking webpage.
