IMPORTANT INFORMATION FOR OWNERS AND OPERATORS OF DIESEL AGRICULTURAL ENGINES

50 HORSEPOWER AND GREATER REQUIREMENT FOR REGISTRATION INFORMATION

Agricultural Diesel engines rated at 50 horsepower and greater, operating in the Antelope Valley Air Quality Management District (AVAQMD) must be registered with the AVAQMD. This requirement is found in District Rule 114, Registration Program for Compression Ignition Engines Used in Small Agricultural Operations and is based on the California Air Resources Board (CARB) Airborne Toxic Control Measure (ATCM) for Stationary Diesel Engines. An ARB fact sheet provides additional information and details on the requirements of the ATCM. The requirements apply to stationary and portable diesel internal combustion engine rated at 50 brake-horsepower and above used in agricultural operations (i.e. irrigation pumps, “sprinkler engines”, generators, well pumps, etc.); however, they will not apply to a diesel engine used to power mobile farm equipment such as a truck or tractor. For current ATCM regulatory language please see the CARB Stationary Diesel Engine ATCM.

Registration applications are now available at the District offices located at 43301 Division Street Suite 206, Lancaster, CA. The cost of the registration is $325 for each engine. Registration must be renewed by owner/operator on a triennial basis.

In addition to the registration, the law requires engines to: 
• be equipped with a non-resetting hour meter and 
• meet the emission standards shown in the compliance schedule.

There may be funding available through the Carl Moyer Program to replace or retrofit this equipment.
