Since November 2009, 100 older diesel trucks servicing the Port of Seattle have been permanently removed from service. … Replacement trucks obtained as part of the ScRAPS Program can qualify for a no-cost exhaust retrofit to further reduce their emissions. The program is designed to help the Port of Seattle meet the goals of the Northwest Ports Clean Air Strategy to remove all trucks with pre-1994 engines from port operations by the end of 2010 and to remove all trucks with pre-2007 engines by 2017. Scrapping these first 100 trucks and replacing them with more modern vehicles will prevent the emission of nearly 1.5 tons of fine particulates each year.
