Enforcement of Off-Road In-Use Regulations
A number of years ago, California developed a series of regulations concerning the emissions of Off-Road equipment currently In-Use. This regulation included requirements for registration, idling restrictions, mandatory retirement or application of after treatment systems.
Due to a variety of conditions, including the economic challenges at the time, a number of the provisions of this regulation were delayed.
On September 13th, 2013, the US EPA granted authorization to the California Air Resources Board (ARB) to enforce the In-Use Off-Road Diesel Vehicle Regulations which will be enforced begining beginning January 1, 2014, for large fleets.
Record Retention Requirements for Sellers of California In-Use Off-Road Diesel Vehicles
Effective June 15, 2008, all sales of equipment with 25 horsepower or greater diesel engines into California MUST include notice to the buyer that his equipment may be subject to retrofit or accelerated replacement/repower requirements. These records MUST be retained for three years after the sale. Violators may be subject to severe civil penalties that could be assessed individually, on a daily basis, for every vehicle in violation.

Early Action Can Result in Lower Compliance Costs
The regulation requires fleets to meet certain emission targets and take specific actions by specific dates. Projections made by Cal ARB staff shows it is likely that fleets will have higher annual costs in the first few years after a fleetís initial compliance date and the costs will decrease in later years. Certain actions taken by fleets prior to their initial compliance date will allow them to accrue (bank) credit, which they can use later to avoid being required to retrofit.

Owners Requesting OEM Assistance
California Fleet Owners Requesting Engine Information
California equipment owners may need assistance from OEMs to secure information on the engine powering their equipment. To comply with current California Air Resources Board (CARB) regulations, equipment owners and operators need to register their fleet's engines with the CARB. The regulations require a level of detail that many equipment owners may not have easily accessible. In many cases, the owners have been instructed to contact the original equipment manufacturer.
