SUBJECT: So Park Marina LDW ProjectAmended Ecology Agreed Order/Cost Share
Agreement
Amount of this request:
$0
Total estimated Port share of project cost:
$200,000
ACTION REQUESTED
Request Commission authorization for the Executive Director to (1) Sign an amended Agreed
Order with the Washington State Department of Ecology to complete a Feasibility Study and
Cleanup Action Plan at the South Park Marina site, and (2) Sign an Addendum to a Potentially
Liable Person Cost Sharing Agreement between the Port, South Park Marina owners, and the City
of Seattle to share the cost and performance of the scope of work required by the amended
Agreed Order.
EXECUTIVE SUMMARY
The South Park Marina (SPM) site is adjacent to Port’s Terminal 117 property, now Duwamish
River People’s Park. The property is known to have contamination (e.g., heavy metals,
polychlorinated biphenyls (PCBs), and petroleum) in soil and groundwater. Washington State
Department of Ecology (Ecology) is requiring three parties South Park Marina owners, the Port,
and the City of Seattle to jointly perform a cleanup of the property. The first phase of the cleanup,
the remedial investigation (RI), was performed under a 2020 Agreed Order (AO). This Amended
AO is to perform the subsequent steps to an RI the Feasibility Study (FS) and Cleanup Action
Plan (CAP).
The Port is a Potentially Liable Person (PLP) at the SPM site in part based on historic ownership
of a small, upland parcel between 1959 and 1970 that is now part of the current SPM property.
On that parcel, the A&B Barrel Company operated as a drum reconditioning business between

1946 and 1961. The City is a PLP based on its connection to PCB disposal and track-out from the
adjacent Terminal 117 property. South Park Marina is a PLP based on its ownership and operation
of the marina. South Park Marina has operated at this location since the 1950s.
The three PLP parties agreed to share responsibility to perform the requirements of the 2020
Ecology AO and each to pay an equal amount, or 33%, toward the cost of the scope of work, on
a preliminary basis subject to later reallocation. The proposed Addendum to the parties’ cost
sharing agreement extends that arrangement to cover the next phase of work for the FS and CAP.
Final allocation of costs will likely be determined after completing the FS and CAP. The City of
Seattle will procure the environmental consulting firm to perform the work using their public
procurement process and will hold the contract with the consultant. All invoices and payables
will be handled by the City and the appropriate portion reimbursed by the South Park Marina and
the Port.
Although funding is not included for this request, the Port’s cost share to complete the FS and
CAP is estimated to be $200,000. Spending for this work was included and approved in the 2026
2031 Environmental Remediation Liability (ERL) Program authorization, which is funded
through the Environmental Liability Fund (ELF) via the tax levy.
JUSTIFICATION
The Ecology amended AO is a binding agreement to prepare an FS and CAP documents by the
PLPs the Port, City of Seattle, and the South Park Marina. The project will formally initiate the
process of determining upland site cleanup or source control efforts at the SPM site to meet EPA
and Ecology’s source control requirements as related to the larger Lower Duwamish Waterway
Superfund Site. The project will also help identify who (Port, City, or South Park Marina) has
responsibility for the follow-on work and will help inform a future process to determine the
relative shares of cleanup liability.
Diversity in Contracting
The City will contract for these professional services, and their contract includes an WMBE
Inclusion Plan that requires the maximum practicable opportunity for successful participation of
minority and women-owned subcontracts (WMBE).
DETAILS
The Statement of Work (SOW) detailed in Ecology’s amended AO requires that the PLPs perform
an FS and CAP for the project site. The FS evaluates and presents to Ecology a range of cleanup
alternatives from which Ecology will choose their preferred alternative. The CAP details the
design criteria and implementation approach of the preferred alternative. Implementation of the
cleanup construction outlined in the CAP will be performed under a future agreement.

Scope of Work
The order SOW will be performed by a professional consulting firm hired jointly by the three PLPs
(Port, City, and South Park Marina). As detailed in Exhibit B of the amended AO, the SOW is
divided into four major tasks:
(1) Task 1 prepare a Feasibility Study (FS)
(2) Task 2 prepare a draft Cleanup Action Plan (CAP)
(3) Task 3 perform State Environmental Policy Act (SEPA) Compliance
(4) Task 4 support Public Participation steps
Schedule
The schedule of the required work is presented in the Ecology order is as follows:
Q3 – 2026
135 days following the notice to proceed
for a consultant to perform the SOW
135 days following Ecology approval of the

ALTERNATIVES AND IMPLICATIONS CONSIDERED
Alternative 1 Do Not Authorize to Sign the Ecology Amended Order
Cost Implications: Not signing the Ecology Agreed Order Amendment may result in the issuance
of an enforcement order by Ecology, or Ecology may elect to perform this work itself. This would
result in the State recovering the cost of the work from the Port, increasing the Port’s estimated
costs by 1.5 to 3 times.
Pros:
(1) May delay the Port’s spending by a year or more while Ecology prepares the
enforcement order.
COMMISSION AGENDA Action Item No. 8f Page 4 of 5
Meeting Date: July 14, 2026
Template revised June 27, 2019 (Diversity in Contracting).
(2) May delay the work and costs while Ecology has to contract and perform the work itself,
then compels the Port to reimburse Ecology for the costs.
Cons:
(1) Increased legal and staff time and efforts to respond to an enforcement order and
provide ancillary support to Ecology to carry out the enforcement order (gain access to
the site, etc.)
(2) The ultimate costs of the work will be much higher if Ecology elects to perform the work
itself.
(3) Not performing this work could tarnish the Port’s reputation with Ecology 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 to Sign the Ecology Amended Agreed Order and begin the required
Statement of Work
Cost Implications: Total project costs are estimated at $600,000, which includes a 30%
contingency to account for additional work due to changing site conditions or requirements by
Ecology. The Port’s preliminary share that it will reimburse the City is 1/3 or $200,000, subject to
reallocation at a future date.
Pros:
(1) Complies with the Order and furthers the Port’s collaborative working relationship with
Ecology.
(2) Takes the next step leading to South Park Marina’s cleanup and long-term protection of
human health and the environment.
(3) Demonstrates the Port’s value of being responsible stewards of community resources
and the environment.
Cons:
(1) None.
This is the recommended alternative.
FINANCIAL IMPLICATIONS
There is no funding request as part of this authorization. Funding for the associated scope of
work is from Environmental Liability Fund and spending was approved in the annual
Environmental Remedial Liability (ERL) authorization (11/5/2025). Further, all project costs
except PLP organization staff and technical support costs will be shared equally between the City,
Port, and Marina. Certain costs may also be eligible for recovery through grants, insurance, or
other PLPs.
