In 1999, SeaCon learned of contamination on their newly acquired property on S. 96th Street and was invited to a Brownfields Presentation given by ECOSS’ brownfields manager, Emery Bayley. ECOSS helped SeaCon get a grant through King County to pay for removal of contaminated material from the creek. Ultimately, SeaCon received the grant but elected to remove the contamination themselves after they learned a Biological Assessment from National Marine Fisheries would be required before they would receive funds.
In March of 2000, SeaCon removed contamination from the creek buffer zone that was capped and used as fill under the building. Construction of building began in Summer 2000. SeaCon’s ten year relationship with ECOSS began at this site, on S. 96th Street. Department of Ecology is now holding a public comment period to remove the site from it’s list of Hazardous Sites.
Proposed Removal From Hazardous Site List
Public comment period: 8/21/09-9/21/09
The Markey Property Parcel 4 site is situated north of South 96th street and east of 10th Avenue South in a commercial and industrial district of King County. The north fork of Hamm Creek runs along the north side of the property. The site has two buildings occupied by a Sherwin Williams Paint Company store, Simplex Grinnell Company and NRC Environmental Services. Prior to the 1970s, the site was a truck garden. Between 1977 and 1978, an estimated 50,000 cubic yards of cement kiln dust (CKD), reportedly from Ideal Cement, were placed on the parcel as fill. Subsequent fill included 1,000 cubic yards of soil that designated as dangerous waste due to its lead content. The property owner sued the company responsible for this fill, Bayside Disposal. Bayside Disposal responded by removing and properly disposing of the dangerous waste. Based on available information, Ecology added the property to the Hazardous Site List in 1992. The site was selected for a Site Hazard Assessment (SHA) and subsequent ranking by the Washington Ranking Method (WARM).
