COMMISSION AGENDA – Action Item No. 8f Page 2 of 5
Meeting Date: July 14, 2026
Template revised June 27, 2019 (Diversity in Contracting).
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.
