SUBJECT:  South Park Marina  Ecology Order and Cost Sharing Agreement 
Amount of this request:                       $0 
Total estimated project cost:          $ 1,000,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) sign an order with the
Washington State Department of Ecology (Ecology) to complete a Remedial Investigation (RI) at
the South Park Marina (adjacent to the Port's Terminal 117 in the south Seattle neighborhood
of South Park); and (2) sign a Potential Liable Party (PLP) Cost Sharing Agreement between the
Port, South Park Marina owners, and the City of Seattle to share the costs for the performance
of the scope of work required by Ecology's order andagency oversight costs. There is no
funding requested for this authorization. 
EXECUTIVE SUMMARY 
The South Park Marina (SPM) site is adjacent to the Port's Terminal 117 property. The property
is known to have contamination (e.g., metals, PCBs, and petroleum) in soil and groundwater.
Ecology is requiring three parties  South Park Marina, the Port, and the City of Seattle to jointly
investigate the extent and nature of contamination at the site. 
The Port, marina, and City are identified as potentially liable parties (PLPs) due to ownership,
operation, or responsibility for release of contaminants during periods between the 1940s and
today. The three PLP parties will share responsibility to perform the requirements of the
Ecology Order. Funding for this work was included in the port's 2019-2023 Environmental
Remediation Liability (ERL) Program. 
The draft Ecology order and project fact sheet were available for Public Comment between
12/10/18 and 1/23/19. In November 2018, the three PLPs presented the project to the South
Park Neighborhood Association and they indicated they are 'on board' with the planned work.

COMMISSION AGENDA  Action Item No.  8f                                Page 2 of 5 
Meeting Date: February 26, 2019 (Corrected March 7, 2019) 
We also engaged with the Duwamish Valley Environmental Justice Pilot partners about the
project. No public comments or concerns have been received. 
JUSTIFICATION 
The Port's participation supports the Century Agenda goal of being the greenest Port, and 
reinforces our commitment of being a responsible steward of community resources and the
environment.  It also supports the emerging strategic focus on social equity by moving the
cleanup forward for a site located in the environmental justice community of South Park. The
Ecology Order is a binding agreement to perform site environmental investigation work by the
Port (and Marina owner and the City). The work required by the order will include direct costs
for consulting and laboratory fees in excess of $300,000. Therefore, signing the Ecology order
requires Commission authorization. The project will formally initiate the process of determining 
upland site cleanup or source control efforts at the marina 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 Marina) has responsibility for the follow-on
work and will help determine the relative shares of cleanup liability. 
DETAILS 
The Port has been identified as a Potentially Liable Party (PLP) at the SPM site because the Port
owned a small, upland parcel within the SPM property between 1959 and 1970. 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 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 invoicing
and payables will be handled by the City, and the appropriate portion reimbursed by the South
Park Marina and the Port. 
The Statement of Work (SOW) detailed in Ecology's order requires that the PLPs perform a
Remedial Investigation (RI) for the project site.  Although not anticipated, the order also
provides for any Interim Actions (i.e., hot spot removal or emergency response) should they be
necessary.  The RI will include the collection and chemical analysis of soil, groundwater, and
stormwater samples to develop an environmental conceptual site model (CSM). The CSM will
enable Ecology and the PLPs to develop an appropriate plan for cleanup of the site and assign
responsibility for the cleanup. The order may be amended in the future to require additional
work by one or more of the PLPs.

COMMISSION AGENDA  Action Item No.  8f                                Page 3 of 5 
Meeting Date: February 26, 2019 (Corrected March 7, 2019) 
Scope of Work 
The order's SOW will be performed by a professional consulting firm hired jointly by the three
PLPs (Port, City, and Marina). As detailed in Exhibit B of the AO, the SOW is divided into four
major tasks: 
(1)   Task 1  Remedial Investigation Work Plan 
(2)   Task 2  Remedial Investigation (field sample collection and lab analysis) 
(3)   Task 2a  Source Control Review Memorandum 
(4)   Task 3  Interim Action(s), if required 
Schedule 
The schedule of the required work associated with the Ecology order is as follows: 
Activity 
Commission authorization to sign PLP           Q1 - 2019 
Agreement and Ecology order 
Prepare an RI Work Plan                        Q3 - 2019 
Perform the RI field work                         Q1/Q2 - 2020 
Source Control Memo                         Q2 - 2020 
Final RI Report                                     Q4 - 2020

consultant costs plus
staff costs 
Remedial Investigation                                    $700,000 
Port Management and Agency Fees                     $300,000 
Total                                                       $1,000,000 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do Not Authorize Signature of the Ecology Order 
Cost Implications:  Ecology has advised that not signing the order would likely result in the
issuance of an enforcement order by Ecology, or Ecology could elect to perform this work itself
(i.e., contract the work to its support consultant). This would increase the Port estimated costs
by 1.5 to 2 times. 
Pros: 
(1) May delay the Port's spending by a year or more while Ecology  prepares an
enforcement order. 
(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 its costs.

COMMISSION AGENDA  Action Item No.  8f                                Page 4 of 5 
Meeting Date: February 26, 2019 (Corrected March 7, 2019) 
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 order (gain access to the site, etc.) 
(2) The ultimate costs of the work will be much higher if Ecology performs 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 the Signing of the Ecology Order PLP (Partner's) Agreement and begin
the required Scope of Work immediately 
Cost Implications: Port's portion of the work is estimated at $1,000,000, depending on the
findings during the work. 
Pros: 
(1)   Complies with the order and furthers the Port's collaborative working relationship
with Ecology and the South Park community. 
(2)   Takes the next step leading to the marina's cleanup and long-term protection of
human health and the environment. 
(3) Demonstrates the Port's value of being a responsible steward of community resources
and the environment. 
Cons: 
(1)   Costs of approximately $1,000,000 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 Port's annual Environmental Remedial Liability (ERL)
authorization.  Certain costs may also be eligible for insurance reimbursement. The three PLP
parties will share responsibility to perform the requirements of the Ecology Order and each will
initially contribute an equal amount, or 33%, toward the costs of the scope of work.  Final
allocation of costs will be determined after more is known about the site.
