Diesel Engine & Equipment Replacement Grant Program

MBARD administers the Carl Moyer Program to meet state and federal clean air requirements and reduce the amount of diesel particulate matter (PM) that would otherwise be emitted. The Moyer program provides funding to encourage replacement of older heavy-duty motors/engines operated in one or more of the Air District’s three counties: Monterey, San Benito, and Santa Cruz. In 2018, MBARD received additional grant funding from the Air Resources Board for the FARMER, Community Air Protection Incentives, and NOx Remediation Measure programs. The types of equipment funded include irrigation pump engines, mobile agricultural equipment, fishing, and commercial marine vessels, and construction equipment.

AB 617 Community Air Protection Program Incentives are part of California Climate Investments, a statewide program that puts billions of Cap-and-Trade dollars to work reducing greenhouse gas emissions, strengthening the economy, and improving public health and the environment — particularly in disadvantaged communities. 

AB 617 Community Air Protection Program Incentives forma parte de las Inversiones del Clima de California, un programa estatal que destina miles de millones de dólares de Cap-and-Trade para la reducción de gases de efecto invernadero, fortalecimiento de la economía y mejoramiento de la salud pública y el medio ambiente – especialmente en comunidades en desventaja.
