Vancouver Testing Diesel Pollution From Trucks

LADNER, BC — A three-month, $130, 000 study to measure diesel pollution from heavy-duty vehicles on Vancouver’s roads and highways began in July, according to the Delta Optimist.

Testing will be done during Summer 2012, using technology involving remote sensing tests so that trucks and buses do not have to stop or slow down when passing the test site.

Infrared and ultraviolet beams from a testing trailer on one side of a road will be directed at the height of a heavy-duty truck’s engine exhaust pipe. The beams go through the exhaust of passing trucks to a “detector,” allowing for analysis of the vehicle’s emissions, the regional district explained.

“This study is a good first step to help us gain better understanding of diesel emissions from the transportation sector in the Lower Mainland, and is consistent with AirCare commitments made by the province,” said B.C. Environment Minister Terry Lake. “The results will help us develop options for reducing diesel emissions in the region moving forward.”

The provincial government’s Commercial Vehicle Safety and Enforcement Branch currently monitors heavy-duty diesel particulate matter emissions through its mobile AirCare On-Road inspection program, which will continue to run tests on heavy-duty diesel vehicles.
