New In-Use Locomotive Regulation
On April 27, 2023, CARB approved the In-Use Locomotive Regulation to transition locomotive operations to zero emissions. Staff have prepared fact sheets to summarize the new requirements for locomotive operators: Locomotive Fact Sheets | California Air Resources Board.
The first reporting deadline is July 1, 2024; initial Spending Account deposits are also due on this date. Locomotive operators that wish to use the Alternative Compliance Plan or Alternative Fleet Milestone Option in lieu of the Spending Account are encouraged to submit applications early to be approved prior to the July 1, 2024, deadline. More information will be coming soon. Please subscribe here to receive additional updates directly.
