British Columbia is mandating the retrofitting of diesel emissions control systems on 1989-1993 model year commercial transport trucks.
The new regulation will require the mandatory installation of Diesel Oxidation Catalyst (DOC) filters, or an equally effective technology, by 2009. In British Columbia, on-road heavy-duty diesel vehicle models 1989-1993 are responsible for 6.8% of overall particulate matter pollution, a high proportion given the relatively small number of vehicles.
Installation of the DOC units will cost approximately $1,200 to $2,500 each and will affect 7,500 vehicles.
A 1989-93 heavy duty diesel vehicle can emit up to 60 times the particulate matter of a newer model. DOC filters reduce emissions by 25 to 50 percent, depending on the type of diesel used and on the engine’s age and characteristics.—Guff Muench, president of Cummins Western Canada
The new regulation will affect only heavy-duty diesel vehicles 5,000 kilograms or more, including on-road commercially licensed diesel vehicles and government-owned fleet vehicles. Recreational vehicles, motor coaches, pickup trucks, construction equipment and unlicensed non-road vehicles will not be affected.
British Columbia is the first jurisdiction in North America to make retrofit technology mandatory, although California is planning to make it mandatory by 2009 as well.
