Kellogg Island - Lafarge Cement
River Mile (RM) 1.0-1.3 West
The Kellogg Island to Lafarge source control area (also referred to as the RM
1.0-1.3 West source control area) is located along the western side of the Lower
Duwamish Waterway (LDW) Superfund Site between 1.0-1.3 miles from the southern
end of Harbor Island. The aerial photograph shows the area of interest which is
bordered on the west by West Marginal Way SW and Burlington Northern Railroad.
The Kellogg Island to Lafarge source control area is bordered by the LDW to the
north and east. The Chemithon Corporation is located to the southwest and Alaska
Marine Lines is immediately south of the Kellogg Island to Lafarge source
control area and Lafarge property. These facilities were discussed in the
Glacier Bay (RM 1.3-1.6 West) source control area Data Gaps Report and Source
Control Action Plan.
The upland areas near this source control area have been heavily industrialized
for decades. Historical and current commercial and industrial operations in the
area include Portland cement production, intermodal transportation, railroad
operations, and synthetic detergents manufacturing.
Sediments in the Kellogg Island to Lafarge portion of the LDW have been
impacted by chemical contaminants from various sources. Before reaching the LDW
sediments the contaminants first affected upland media including surface water,
groundwater, soil, and air.
The following chemicals are considered to be contaminants of concern in the
Kellogg Island to Lafarge source control area because they could possibly
re-contaminate Lower Duwamish Waterway sediments once it has been cleaned up.
||PCBs (polychlorinated biphenyls)
||Polynuclear Aromatic Hydrocarbons (PAHs)
|Bis (2ethylhexyl) phthalate
Ecology is the lead for source control for the LDW Superfund site. Source
control is the process of finding and then stopping or reducing as much as
possible releases of pollution to the river.
The Kellogg Island to Lafarge drainage basin outlines the area where sources
need to be controlled (see picture). The way contaminants enter Lower Duwamish
Waterway sediments from this source control area include: direct discharges via
piped outfalls, bank erosion from adjacent properties, surface runoff from
adjacent properties, groundwater discharge, air deposition, and spills directly
to the inlet. Ecology looks at all these possible sources for the Kellogg Island
to Lafarge source control area in order to determine what source control work
needs to be done.
Source Control Action Plan
Ecology hired a contractor to put together a
Existing Information and Data Gaps report (7 mb) for RM 1.0-1.3 Kellogg Island –
Lafarge Cement source control area. Ecology and its contractor used the report
to develop a Source Control Action Plan
(1.7 mb) for the area. This plan describes the source
control actions that are necessary to reduce the potential for sediment
