The California Air Resource Board announced administrative changes in implementing the reporting requirements of the Truck and Bus Regulation. The Jan. 31 reporting date is being extended to March 30 to give fleet owners more time to submit their fleet information. Reporting is required for fleet owners to take advantage of flexibility in the regulation.

CARB says this change does not extend the particulate matter filter and other compliance requirements that began Jan. 1. To avoid potential enforcement action, CARB advises fleets that have not met these requirements to make every effort to bring the fleet into compliance as soon as possible.

The regulation applies to diesel-fueled trucks and buses with a gross vehicle weight rating greater than 14,000 pounds that are privately or federally owned and to publicly and privately owned school buses. Local and state government-owned diesel fueled trucks and buses already are subject to other CARB regulations.

CARB says the extension will provide more time for fleets to report to take advantage of flexibility in the regulation as follows:
All flexibility options that required reporting by Jan. 31 will remain available to fleet owners that report by the extended deadline;
All fleets that are using mileage-based extensions also must report odometer readings from Jan. 1; and
Owners of two-engine sweepers with Tier 0 auxiliary engines must report hour meter readings from Jan. 1.
