This Department of Ecology LISTSERV provides information on efforts to control sources of pollution to the Lower Duwamish Waterway Superfund Cleanup site.
Per the Task Force request, below is an example of our Duwamish updates listserv. Folks can sign up here: http://www.ecy.wa.gov/maillist.html
For folks who want information just about the Pollutant Loading Assessment, they can find info on this webpage: http://www.ecy.wa.gov/geographic/GreenDuwamish/pla.html
If they want to observe the Technical Advisory Committee meetings, these are open. Folks can contact Joan Nolan (joan.nolan@ecy.wa.gov) if they want to be added to that smaller list.

Seattle metal recycler fined $64,000 for pollution discharges to Duwamish River
Ecology fined Seattle Iron and Metals Corporation $64,000 for discharging stormwater with excessive levels of several pollutants into the Duwamish River. The company’s monitoring records showed 27 violations of pollutant limits from February 2015 through December 2016. On June 20 and 21, 2016, stormwater was allowed to bypass the treatment system, which resulted in four additional violations. Seattle Iron and Metals Corporation also failed to submit monitoring reports for the fourth quarter in 2015. The company paid the fine. Ecology’s water quality penalties go to the state’s Coastal Protection Fund which issues grants to public agencies and tribes for water quality restoration projects.
Site Work begins for the Georgetown Wet Weather Treatment Station
King County is beginning site demolition and soil remediation work at the home of the future Georgetown Wet Weather Treatment Station. The station will treat combined sewage and stormwater flows from the Michigan and Brandon combined sewer overflow basins. Ecology’s Water Quality Program reviewed the plans for this project to ensure that it meets the state’s water quality laws. Ecology is reviewing the 90% design documents for the treatment facility, conveyance system improvements, and the facility’s outfall in the Duwamish River (where treated wastewater will discharge).

City of Seattle has begun testing stormwater treatment technologies at Riverside Drive as part of the South Park Water Quality project.
This stormwater treatment facility will treat runoff from the 7th Avenue storm drain basin in South Park. The project is part of Seattle’s Integrated Plan to protect Seattle’s waterways, approved by Ecology and EPA, which addresses control of combined sewer overflows (CSOs) and includes stormwater projects.
