A Port of Tacoma study revealed that 90 percent of the drayage trucks serving the harbor meet the port's clean-truck standards for 2010, and newer trucks are steadily replacing older, polluting trucks as the program moves forward.
Tacoma is participating with the Port of Seattle and Port Metro Vancouver in the Northwest Ports Clean Air Strategy, a program designed to reduce harmful diesel emissions in the region.
A recent study indicates that 90 percent of the harbor drayage trucks in service in Tacoma are model year 1994 or newer, which is the 2010 standard for reducing diesel emissions. That number is 4 percent higher than last year. About 6 percent of the trucks are model year 2007 or newer, which means they meet the standard the port has set for 2015. That number is up 2 percent from last year.
The study covered some 3,100 drayage trucks serving the harbor. The study also determined that the newer, cleaner trucks call more frequently in the harbor than do older trucks.
