Sediment that has accumulated behind the pump station since its construction has become an operational concern for the facility and must be removed. The project is normal maintenance and repair of an existing structure and therefore qualifies for a Shoreline Exemption from the City. The County proposes to remove approximately 2,900 cubic yards of sediment from the pump station forebay. Analytical results indicate sediments have elevated levels of arsenic, cadmium, total petroleum hydrocarbons, phthalates, and polychlorinated biphenyls. Prior to dredging, a staging and sediment stockpiling, decanting, and watering treatment area will be constructed on the south side of the river within the pump station parking lot and on a maintained grassy area east of the lot. The staging area will include a pad to support a crane that will lift equipment into and from the riverbed, as well as an access road to the south bank of the river. The work area will be isolated from the river by constructing a temporary flow diversion structure spanning the entire width of the river. The river will be dewatered using the pump station pumps until water levels are too low for the pumps to work or turbidity levels are too high to discharge water to the Black River, at which point portable pumps will be used to remove the remaining water. Water will be pumped through bypass pipes on the north side of the river downstream of the pump station unless the water is too turbid, in which case it will be pumped directly to the decant facility for treatment before being discharged back into the Black River. Pumps will remain on site during excavation to remove any water that may seep past the cofferdam. Fish will be excluded from the in-water work zone prior to and during dewatering using a combination of seine and dip netting. Sediment will be dredged from the riverbed using conventional excavation equipment such as clamshell buckets or backhoes. The sediment removal area extends approximately 100 feet DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT 1 O:\proj\Y2010\10-04766-065\WP\Reports\JARPA\main text\z-obsolete Renton land use master app.doc Rev: 02/2015 Planning Division LAND USE PERMIT MASTER APPLICATION PROPERTY OWNER(S) PROJECT INFORMATION NAME: Tom Bean PROJECT OR DEVELOPMENT NAME: Black River Pump Station Sediment Removal Project ADDRESS: King County Water and Land Resources Division, Rivers and Floodplain Management Section, 201 S.
