(Order) requiring the Port of Seattle to perform an Engineering Evaluation and Cost Analysis
(EE/CA) at Terminal 108, 
(2) Sign a Potential Responsible Party (PRP) Cost Sharing Agreement between the Port of
Seattle, City of Seattle, and King County to share the costs to perform the scope of work
required by EPA's Order including EPA oversight costs; and, 
(3) Procure  and  execute  a  joint,  project-specific,  professional  environmental  consulting
contract to prepare the EPA EE/CA in the amount of $3,000,000. If needed, execute future

required by EPA under the Order. 
EXECUTIVE SUMMARY 
Terminal 108 (T-108) has been identified as a potential upland source control site for the Lower
Duwamish Waterway Superfund Site due to its adjacency to the river and the past uses at the
site. Source control is the process of identifying sources of contamination, then stopping or
reducing them before they reach the river.

Meeting Date: May 12, 2020 
Historically, the T-108 site was a municipal sewage treatment plant between 1938 and 1969,
first owned and operated by the City then later by Metro/King County. In 1975, the U.S. Army 
Corps of Engineers negotiated an agreement with Chiyoda, the property owner at that time, to
dispose of dredge spoils containing PCBs at T-108. The dredge spoils came from Slip 1, about
2,400 feet upstream of T-108, where a General Service Administration contractor had dropped
a transformer containing 265 gallons of concentrated PCB fluid. 
The Port purchased the property in 1984. As the current owner, the Port has performed site
investigations in coordination with the Department of Ecology (Ecology) to study and address
possible source control issues. More recently, Ecology asked the U.S. Environmental Protection
Agency (EPA) to take the lead on this site due to the federal government's role in contributing
to suspected contamination at the site.  Subsequently, EPA directed the Port to perform a
Preliminary Assessment and Site Investigation (PA-SI), which was completed in December 2018. 
Using the results of the PA-SI, EPA identified several Potential Responsible Parties (PRPs) that
may have liability on the future investigation and cleanup of T-108; some, including the Port
and City, will be signatories to the Order. These PRPs include the Port, City of Seattle, King
County, Chevron, Chiyoda, LaFarge, and the US Air Force. The Port, City and County negotiated
with EPA to reach agreement on the Order to perform an Engineering Evaluation and Cost
Analysis (EE/CA).   An EE/CA is similar to a state performed Remedial Investigation and
Feasibility Study (RI/FS). 
The Port, City and County will share responsibility to perform the requirements of the EPA
Order and each will contribute towards the costs to prepare an EE/CA.  The cost-sharing
percentages are subject to reallocation in the future. Final allocation of the shared EE/CA costs
between the Port, City and County will be determined after more is known about the site, and
the parties will pursue reimbursement from other, non-participating PRPs as well. The Port will
procure the environmental consulting firm to perform the EE/CA work using our public
procurement process and the Port will hold the contract with the consultant. All invoicing and
payables will be handled by the Port and the appropriate portion reimbursed by the City and
County. 
Today, most of the terminal is used by our tenant as an off-dock facility for storage and
maintenance of empty cargo containers. 
Funding for this work was included in the 2020-2024 Environmental Remediation Liability (ERL)
Program. Accordingly, additional funding is not requested at this time. 
JUSTIFICATION 
The EPA Order is a binding agreement to perform work by the Port, therefore the signing of the
EPA Order requires Commission authorization. The project will formally initiate the process of
determining upland site cleanup and/or source control efforts at T-108, as necessary and
required, to meet EPA and Ecology's source control objectives and requirements as related to

the larger Lower Duwamish Waterway Superfund Site. The project will also help EPA and the
PRPs substantiate the appropriate PRPs and their allocated share of the costs for follow on
source control and cleanup, as appropriate. 
Diversity in Contracting. For the upcoming  procurement, the project team has contacted the
Port'sDiversity in Contracting Department and will establish a women-and minority-owned
business enterprise (WMBE) aspirational goal (likely 15%) and inclusion plan. 
DETAILS 
The Statement of Work detailed in the Order requires that the Port, City, and County perform
the work necessary to prepare an Engineering Evaluation and Cost Analysis. These work tasks
are routine site assessment efforts and are used to determine: a) what is the source, nature
and extent of the release; b) is there an imminent threat to human health or the environment;
c) are there sources of contamination to the river; and, d) is a removal action necessary. 
Scope of Work 
As presented in the Statement of Work attached to the Order, the PRP Group will perform the
following tasks: 
1.  Prepare an EE/CA Work Plan, that includes the following appendices: 
a.  Quality Assurance Project Plan 
b.  Health and Safety Plan 
c.   Groundwater Monitoring Plan 
2.  Conduct Site Investigation 
a.  Field investigation work, including drilling, monitoring and sampling 
b.  Laboratory analytical work and data validation 
3.  Prepare the EE/CA Report that includes the following sections: 
a.  Site Characterization, including data presentation and Conceptual Site Model 
b.  Assessment and Need for a Removal Action 
c.   Identification and Analysis of Removal Action Alternatives, including cost 
d.  Recommended Removal Action Alternative 
Schedule 
The schedule of the required work is based on the Statement of Work in the Order. The tot al
time to complete this work is approximately 48 months.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do Not Authorize Signature of the Order 
Cost Implications: Not signing the Order may result in the issuance of an enforcement order by
EPA, or EPA may elect to perform this work itself. This would result in the EPA recovering the
cost of the work from the Port, increasing the Port's estimated costs by 1.5 to 3 times, roughly
$5 to $10.5 million (from $3.5 million). 
Pros: 
(1) May delay the Port's spending by a year or more while EPA prepares the enforcement
order. 
(2)   May delay the work and costs while EPA has to contract and perform the work itself,
then compels the Port to reimburse EPA for the costs. 
Cons: 
(1)   Increased legal and staff time and efforts to respond to an enforcement order and
provide ancillary support to the EPA to carry out the enforcement order (gain access
to the site, etc.) 
(2)   The ultimate costs of the work will be much higher if EPA elects to perform the work
itself. 
(3) Not performing this work could tarnish the Port's reputation with EPA and the
community as having a commitment to public health and being a steward of
community resources and the environment. 
This is not the recommended alternative. 
Alternative 2  Authorize the Signing of the Order and begin the required Statement of Work 
Cost Implications:  Likely $3,500,000  costs shared with our partners  but may increase to
$4,000,000 or more depending on the findings during the work. 
Pros: 
(1) Complies with the Order and furthers the Port's collaborative working relationship
with EPA.

(2) Takes the next step leading to Terminal 108's cleanup and long-term protection of
human health and the environment. 
(3)   Will likely lead to the identification of other responsible parties for past releases. 
(4) Demonstrates the Port's value of being responsible stewards of community resources
and the environment. 
Cons: 
(1)   Costs up to $2,000,000 (approximately half of the estimated costs) by the Port to
complete the Order's Statement of Work. 
This is the recommended alternative. 
FINANCIAL IMPLICATIONS 
There is no funding request as part of this authorization. Funding for the associated scope of
work and costs is included in the annual Environmental Remedial Liability (ERL) authorization 
(tax levy).   Project costs will be shared by the Port, City, County, subject to reallocation after
the EE/CA is complete. As the contracting party, the Port will pay all costs upfront, and the City
and County will reimburse the Port for their respective shares. Certain costs may also be eligible
for insurance reimbursement. Cost recovery from other PRPs who declined to participate in the
EE/CA will be pursued in the future.
