Lower Duwamish Waterway
Source Control Investigation
Crowley Marine Services 8th Avenue South
 Site Location
This approximately sixteen acre site is located at 7400 8th Avenue South, in
Seattle, Washington, on the east side of the Lower Duwamish Waterway. The site is bordered by Puget Sound Truck Lines on the west,
Markey Machinery and the Sternoff Metals site on the north, the Duwamish River
on the south, and Slip 4 on the east. 8th Avenue Terminals owns the site
and a portion of
the sediments in Slip 4. Final site boundaries will be defined by the extent of
contamination determined during the RI.
Site Background
Crowley Marine Services owned this site from 1993 to 2008 when they transferred
ownership to 8th Avenue Terminals, Inc. in October 2008.
Both companies are subsidiaries of Crowley Maritime Corporation. 8th
Avenue Terminals, Inc. is negotiating with a potential tenant for the lease
of one half of the site. The other half of the site is leased to the
Union Pacific Railroad Company through the end of July 2009. 8th
Avenue Terminals, Inc. is negotiating with a number of potential tenants
interested in leasing that portion of the site.
Historic uses of the site date back to the early 1900’s, when the site was
residential. In the 1920s, a pipe and chain manufacturing
facility occupied the southern portion, and included a pipe-dipping vat and
furnace. Excelsior, a packing material made from wood shavings, was
manufactured on the northern portion.
During the 1920s to 1950s, logs were rafted in Slip 4 for a sawmill, lumber
yard, and wood treating company. The company had a pole dipping tank
and treated pole storage yard. The property was also used by an
aluminum window and sash manufacturer. A steel culvert manufacturing
company occupied the site in the 1960s. In the 1980s, most of the site
was paved for Crowley’s container storage and barging operation.
Contamination
Contamination at this site is from heavy industrial use since the 1920’s.
Soil contaminants include:
- Metals such as arsenic and copper.
- Polychlorinated biphenyls (PCBs).
- Carcinogenic polycyclic aromatic hydrocarbons (cPAHs).
Groundwater contaminants include arsenic, copper, and cPAHs, and sediments have
PCBs and PAHs.
 Agreed Order
The potentially liable party (PLP), 8th Avenue Terminals, Inc., and the Department of
Ecology have negotiated an Agreed Order to conduct an investigation at this
site. Under the Agreed Order, 8th Avenue Terminals will conduct a Remedial
Investigation/Feasibility Study (RI/FS) and prepare a Draft Cleanup Action Plan
(DCAP) at the site. The purpose of the Remedial Investigation is to define the
nature and extent of contamination at the site and find if it is contributing to
the sediment contamination in the Lower Duwamish Waterway.
The Feasibility Study will use the results of the Remedial Investigation to
evaluate and choose measures to prevent such releases from the site. Ecology has
prepared a Scope of Work that describes the planning and technical work that
will be done to complete the RI/FS for the site. It also provides an approximate
schedule for completing the RI/FS.
