California's Diesel Risk Reduction Plan

In-Use Stationary Diesel Agricultural Engines

Stationary diesel engines used in agricultural production are a source of diesel exhaust particulate matter (diesel PM), oxides of nitrogen (NOx), and reactive organic gases (ROG) in California. These engines are typically used to pump water, provide power, and run wind machines. The Air Resources Board (ARB) is working with the agricultural community, air districts, environmental and citizen groups, and the public to develop a control measure to reduce the emissions and health risks associated with in-use stationary agricultural engine diesel exhaust. New and newly-purchased used stationary diesel agricultural engines are currently regulated under the ATCM for Stationary Compression Ignition Engines. In addition, California's local air districts are also developing regulations to reduce NOx emissions from stationary diesel agricultural engines. These regulations are required by Senate Bill (SB) 700 (Florez, 2003).

~Now Available~ Financial assistance and incentive funding is available for replacing/retrofitting in-use stationary diesel agricultural engines. For more information, see factsheet.
Special Alert: Application windows for PG&E's and SCE's Agricultural Internal Combustion Engine Conversion Incentive Programs are scheduled to close July 31, 2007. For more information about these programs, see PG&E or SCE.
