A Healthy Breathing Environment For Every Bay Area Resident

Off-Road Vehicles

Learn how to upgrade or replace off-road diesel equipment with funding from the Carl Moyer Program. This program aims to cut air pollution from heavy-duty diesel engines in California.

Project Types

The Air District is currently accepting applications for Off-Road Equipment projects. Funding is offered on a first-come, first-served basis until all funds have been spent. Applications must be complete to be considered for funding.

Funds are available for the following project types:

Equipment replacement - replace old equipment with the cleanest available equipment, including alternative-fuel and zero-emissions equipment.
Engine retrofit - install an emission control device.
Engine replacement (repower) - replace an old engine with the cleanest emission-certified engine available, including alternative-fuel and zero-emissions equipment.
Infrastructure - install or expand electric and alternative fuel infrastructure to fuel or power off-road equipment.

Eligibility

Basic Criteria

Public and private fleet owners are eligible to apply. The following equipment is generally eligible for grants; however, you must also determine the regulatory status of your equipment (see next section):

Off-road equipment: loaders, tractors, dozers, excavators, scrapers, forklifts, ground support equipment, etc.
Portable engines/equipment: an engine designed and capable of being carried or moved from one location to another - e.g. portable generators, concrete pumps, wood chippers, water pumps, etc. To be eligible for funding the existing equipment must be registered with the California Air Resources Board's Statewide Portable Equipment Registration Program.
Equipment with 25 horsepower or greater diesel engines.
Equipment that meets the current calendar year of regulatory compliance or is exempt from regulation (agricultural equipment).
Equipment operating within the Air District’s boundaries, with priority given to those operating in areas highlighted in the Priority Community Map(919 Kb PDF, 1 pg, posted 05/16/14) or in Community Health Protection communities.

Public or private organizations that own a variety of equipment types are encouraged to apply for grants in other categories, especially if the application includes fueling or charging infrastructure.

Rules and Regulations

The California Air Resources Board (CARB) established regulations for off-road equipment and portable engines that vary according to the engine type and the use of the equipment. The following CARB web pages can assist you in determining if your fleet meets applicable CARB fleet requirements:

Most diesel equipment operating in construction, mining, rental, airport equipment, and heavy industry is regulated under the CARB Off-Road Regulation.
CARB Statewide Portable Equipment Registration Program (PERP).
Off-road equipment powered by Large Spark Ignition (LSI) engines are regulated under the CARB LSI Fleet Rule: examples include agricultural, construction, and general industrial equipment powered by gasoline, liquefied petroleum gas, and other fuels.
Off-road equipment operating at ports and intermodal rail yards are regulated under the CARB Cargo Handling Equipment Regulation: examples include yard trucks, hostlers, cranes, top handlers, side handlers, forklifts, and loaders.
Mobile off-road equipment operating at least 50% of the time in qualifying agricultural activities is likely exempt from regulation.
Compliance dates will vary by regulation and fleet size.
For more information about off-road regulations, call the CARB regulatory hotline: 1-866-6-DIESEL (1-866-634-3735).

Co-Funding with Other Incentives

Additional funding may be available for your off-road equipment project. Eligible projects can use additional funds from other incentive programs (“co-funding”). Private fleets may be able to co-fund up to 95 percent of eligible costs, while public agencies may be eligible to co-fund up to 100 percent of eligible costs. Incentives may be available for zero- and near-zero emissions, hybrid, and natural gas equipment. Co-funded projects must meet the requirements for each funding source.

How to Apply

Understand any applicable State of California fleet rules that may apply to your fleet.
Examine your fleet and determine which types of equipment might qualify for funding.
Start collecting information on your equipment or engine, and any additional supplemental documentation needed for your application.
Review the application user guide and Chapter 5 “Off-Road Equipment” of the current California Air Resources Board 2017 Carl Moyer Program Guidelines.
Contact your engine or equipment dealer to discuss replacement options for your existing equipment. Applicants for off-road equipment are asked to work with an Air District-approved equipment replacement dealer; see information on the Off-Road Equipment Replacement Program below.

Off-Road Equipment Replacement Program (ERP)

Funding is available to:

Replace an existing old piece of equipment with cleanest available replacement equipment (with possible retrofit option) up to 90 percent of the project cost.

This project option is most appropriate when:

the existing equipment is still fully-functional with regular use over the past two years,
there is no logical replacement engine option available from the manufacturer, and
the diminished value of the existing piece of equipment does not justify further investment.

The Air District has contracted with Bay Area equipment dealers to assist applicants to apply for off-road equipment replacement projects. The Air District will also work with non-contracted dealers, on a case-by-case basis, for projects where the proposed equipment is for advanced technology (e.g. zero-emissions equipment) and/or is not available locally. A complete list of Air District-contracted Bay Area equipment dealers can be found below.
