History of the Carl Moyer Program

Variety of Moyer-eligible equipment

The Carl Moyer Memorial Air Quality Standards Attainment Program (Moyer Program) provides incentive funds for the incremental cost of cleaner than required engines and equipment. Eligible projects include cleaner on-road, off-road, marine, locomotive and stationary agricultural pump engines, as well as forklifts, airport ground support equipment, and auxiliary power units. The program achieves near-term reductions in emissions of oxides of nitrogen (NOx), particulate matter (PM), and reactive organic gas (ROG) which are necessary for California to meet its clean air commitments under the State Implementation Plan. In addition, local air districts use these emission reductions to meet commitments in their transportation conformity plans, thus preventing the loss of federal funding for local areas throughout California. In addition particulate matter (PM), a component of diesel exhaust, has been identified as a toxic air contaminant by the Air Resources Board.

Legislative Changes

Changes in State law have expanded the Carl Moyer incentive program to include agricultural sources of air pollution as well as cars and light-duty trucks. AB 923 (Firebaugh, 2004) provides additional funding for the Moyer Program from an adjustment to the tire fee, and authorizes local air districts to increase motor vehicle registration fees by up to $2 for programs to reduce air pollution. As part of the fiscal year 2004-2005 budget, SB 1107 adjusted the Smog Check fee while extending the newer-vehicle Smog Check exemption, providing additional funding for the Carl Moyer Program. AB 923 and SB 1107 combined provide up to $120 million a year of incentive funding available to help clean up California's air. AB 8 (Perea) extended a portion of the funds available to the Moyer Program from January 1, 2015 to January 1, 2024, and also directed ARB, in conjunction with the local air districts, to convene a working group to evaluate the Moyer Program's policies and goals. The work group identified several areas in which the program could be made even more effective, and subsequently, SB 513 (Beall, 2015) incorporated many of the suggested changes to the Moyer Program, granting both ARB and the air districts additional flexibility in several areas of program implementation.
