What we’ve done to reduce pollution in Georgetown/South Park? • We partnered with the NW ports to update the NW Ports Clean Air Strategy • Reduce diesel exhaust by 80% by 2020 • Ongoing, Sc. RAPS 2 with Port of Seattle • To date, scrapped 397 older trucks and funding for 110 more this year. • Diesel Solutions Program examples: • Retrofits at the Port of Seattle • Retrofitted all school buses in Puget Sound • Inspect and permit industrial sources • Example: PSCAA gave oral argument to the federal District Court regarding if PSCAA has authority to require Ardagh (glass manufacturer on E Marginal Way S) to install a proposed Reasonably Available Control Technology.
