King County & City of Seattle Public Utilities Inspections in the Lower Duwamish Waterway Area Introduction | Project Description | Links & Contacts | Project Library | Phthalates Introduction Download project documents Inspections in the Lower Duwamish Waterway Area, Information Flier Progress Reports June 2005 Reporting period: January - June, 2005 The U.S. Environmental Protection Agency listed the Lower Duwamish Waterway as a Superfund site in 2001 because of the presence of contaminated sediments. Before these sediments can be cleaned up permanently, ongoing sources of contaminants must be controlled. To prevent recontamination of the sediments, the City of Seattle and King County are working together to identify and control sources of pollution in the areas served by county/city storm drains and combined/sanitary sewers. Project Description King County and City of Seattle, as operators of the local storm and sanitary sewer systems, are working together to reduce the amount of pollutants discharged to the Lower Duwamish Waterway from our systems. This cooperative program involves a number of activities: working with local property owners to control the sources of pollution in areas draining to our systems investigating our combined/sanitary sewer systems to reduce the number of overflow identifying locations where contaminants could be entering the system through leaks and cracks in the piping. The project is conducting a series of inspections of local businesses. The inspection process focuses on identifying and controlling sources of chemicals that could reach the waterway through stormwater or combined sewer overflows or both. Generally, we need to determine whether businesses are likely to do the following: store or use chemicals of concern generate hazardous waste discharge industrial wastes to the sewer manage possible pollutants in a way that may introduce them into storm drains. Who is doing the inspections? Staff from the following agencies are conducting inspections: the King County Industrial Waste Program, the Local Hazardous Waste Management Program in King County, City of Seattle Public Utilities, and Public Health – Seattle & King County. Ecology staff may also assist with some of these inspections.
