In August 1998, the Air Resources Board (ARB or Board) identified particulate matter (PM) exhaust from diesel-fueled engines as a toxic air contaminant. ARB adopted a Diesel Risk Reduction Plan (Diesel RRP) in September 2000, which recommends a number of control measures to reduce the risks associated with diesel particulate matter (PM) and achieve a goal of 75 percent PM reduction by 2010 and 85 percent by 2020. Our mission is "To protect the health of Californians by retrofitting all in-use diesel engines in California with devices that reduce diesel particulate emissions to near zero, in the shortest possible time."
To achieve success in the plan, we are adopting a series of rules and control measures. We began our rulemaking in February 2000 with the adoption of the Public Transit Bus Fleet Rule and Emission Standards, which requires transit agencies to decrease emissions from urban transit buses. Transit agencies are required to add emission control systems to the buses to reduce PM, beginning in 2002. Now we are working on the proposed control measure for diesel particulate matter from on-road heavy-duty diesel-fueled residential and commercial solid waste collection vehicles. From here we plan to decrease emissions from the remaining in-use on- and off-road heavy-duty diesel fleets. We plan to protect public health in all communities in California by implementing this proposed control measure for solid waste collection vehicles.
The solid waste collection vehicle category is defined as:

1.

Heavy-Duty Diesel Vehicles Greater than 14,000 Pounds GVWR

2.

Used to Collect Residential and Commercial Waste 

3.

Front, Side and Rear Manual and Automatic Loaders, Rolloffs

4.

Hauler charges a fee
To help assess technical issues and identify opportunities to implement a successful California diesel retrofit program, the ARB has formed an International Diesel Retrofit Advisory Committee (IDRAC).
Look for additional control measures to be developed over the next three to four years. Each control measure will be linked to the Diesel Risk Reduction Plan web page.
