Lower Emission Heavy-Duty Engines

The Carl Moyer Memorial Air Quality Standards Attainment Program (Carl Moyer Program) is named after Dr. Carl Moyer in recognition of his work in the air quality field.  This program is designed to provide grants for the incremental cost of new low-emission heavy-duty engines and low-emission retrofit technologies.  The exhausts from heavy-duty diesel engines are a significant source of smog-forming emissions.  Nitrogen Oxides (NOx) from diesel engine exhaust are identified as a major smog-forming emission.  Furthermore, the California Air Resources Board (CARB) has identified the fine particulate matter (PM) from the exhaust of heavy-duty diesel engines as a toxic air contaminant (TAC).

2004/2005 Carl Moyer Program Summary

The Colusa County Air Pollution Control District (CCAPCD) implemented the Carl Moyer Program for the 2004/2005 fiscal year.  A total of thirty-four applications were received.  Applications were evaluated on the basis of emission reductions, feasibility, environmental impacts, and cost-effectiveness criteria.  A total of fifteen applications were approved to be funded by the Carl Moyer Program.  The program targeted the reduction of nitrogen oxides (NOx) and particulate matter (PM) emissions.  Annual reductions for the next seven years are expected to be about 28.02 tons per year for NOx and 1.21 tons per year for PM.

Stationary Agricultural Engines

 Applicants may request Carl Moyer Program funds for new purchases, repowers, replacements, and/or retrofit projects for stationary agricultural engines (stationary agricultural irrigation pump engines).

 New Purchase – Applicants may request funding for the incremental cost of a new irrigation pump engine if the engine is equipped with an electric motor.

 Repower – Applicants may request funding for the incremental cost of a new internal combustion irrigation pump engine in replacing the existing irrigation pump engine.  The incremental cost for a repower project is the difference in the cost for a new low-emission engine and the cost of rebuilding the existing engine.

 Electric Motor Repower – Applicants may request funds for the incremental cost of a new electric irrigation pump engine in replacing the existing internal combustion diesel engine.  The cost of electric line extensions is not eligible for funding.

 Retrofits – Applicants may request funds for the incremental cost of the installation of an emission-reducing modification to the existing irrigation pump engine.  The incremental cost is the difference between the cost of rebuilding the existing engine to its original uncontrolled specifications and the cost of rebuilding the existing engine with emission certified parts.
