ACTION REQUESTED:
Request authorization for the Chief Executive Officer to execute an amendment to add $2,000,000
to the AECOM professional service contract to support the investigative work required for the
Lower Duwamish Superfund Site (P-00314929) for a total contract value of $15,500,000. In
addition, this memo provides notification to the Port of Seattle Commission in accordance with
RCW 53.19.060 that the amendment for AECOM exceeds 50% of the original contract value.
(The contract will expire on December 31, 2014.) 
SYNOPSIS:
This contract supports the investigative work required for the LDW Superfund Site under the
Administrative Order on Consent (Order) that the Port and the other potentially responsible parties
(PRPs) have signed with the U.S. Environmental Protection Agency (EPA) and Washington State
Department of Ecology (Ecology). Costs for this contract is shared among the PRPs which formed
the Lower Duwamish Water Group (LDWG) which is made up of the Port, the City of Seattle,
King County, and Boeing. The Port is responsible for managing the joint consulting contracts. 
The procurement for the AECOM contract was originally authorized in 2004. The services
included in the procurement were for completing the Feasibility Study (FS) and support during
negotiation of the Cleanup Order (Record of Decision (ROD). The original contract amount was
$800,000 to cover the first year of contract work. To manage the contractor and because the
budget that this work was performed under was approved annually, historically (before CPO-1) we
had amended the contract on an annual basis to cover the next years required work. In 2009 to be

consistent with CPO-1, the contract was amended to increase the contract amount by $7,019,000 to 
an amended total of $13,500,000 to reflect the anticipated full cost and time needed to complete
the entire scope of work for the FS which is the basis for the Record of Decision.  The Port
anticipated that the work would be completed by 2012 and set the contract expiration date to be
December 31, 2012. However, based on the delay of the release of EPA's Proposed Plan (which
outlines the cleanup approach based upon alternatives in the FS) to January 2013, the new
schedule anticipates the ROD be completed in 2014. 
The current authorized contract amount has almost been expended based on a higher level of effort
required to complete the FS document. To complete the FS and the additional studies EPA and
Ecology have identified that they will request under the Order, additional funds will be needed and
the contract will need to be extended. Accordingly, the Port is requesting authorization to add
$2,000,000 to the contract, for a total of $15,500,000.  The amendment to the contract exceeds
50% of the cumulative value of the initial contract and this memorandum constitutes Commission
notice in accordance with RCW 53.19.060. 
There is no funding request as part of this authorization. Funding is included in the annual
Environmental Remedial Liability (ERL) authorization.
BACKGROUND: 
Under an existing Memorandum of Agreement (MOA), the Port functions as the contracting agent
for a group of PRPs (i.e. governments and private parties that signed on to the Order under a cost
sharing agreement approved by Commission). Three -quarters of the contract costs are reimbursed
by the other PRPs on a routine basis. The other PRPs include the City of Seattle, King County,
and Boeing, as represented by LDWG. 
The Order contains a general outline of a scope of work (SOW). The scope of work for this
contract is tied to the SOW in the Order. S pecific defined tasks were identified during each stage
of work plan development, which occurred after the consultant was hired to perform the general
scope. The work performed under this contract is managed through individual service directives
that are tied to the budget as approved and managed under the ERL authorization budget for the
site. 
At the time of the last contract amendment in 2009, it was expected that the FS would be final, the
proposed plan would have come out for public comment and the ROD would be completed by
2012. The current schedule is for the Proposed Plan to go out for public comment in January 2013
and the ROD to come out in early to middle 2014. The work required by the Order is still ongoing
and is anticipated to continue until December 2014. The bulk of the work is almost complete (draft
final FS is scheduled to go out for a 60 day public comment period in October), and the consultant
in place is deeply familiar with all of the studies and reports, since they have produced them.
PROJECT JUSTIFICATION:
This project will complete the requirements specified for this site in the Order. 
The purpose of the project is to fulfill the legal obligations under the Order to complete the RI/FS
and associated studies. These documents are then used by EPA to select cleanup actions, as
documented in the Proposed Plan (January 2013) and ROD (2014).

PROJECT SCOPE OF WORK: 
The scope of work (SOW) for this project is completion of activities identified in the Order SOW,
including the RI, the FS, Proposed Plan/ROD Support, and associated studies as directed by EPA. 
Additional activities requiring $2,000,000 of additional funding under the AECOM contract
include: 
Proposed Plan/ ROD Support: $500,000 
Additional Studies: $1,500,000 
Project Schedule: We anticipate all work associated with the Order SOW be completed by
December 2014. Design and construction of cleanup is not included in the current Order or these
contracts. 
FINANCIAL IMPLICATIONS:
Budget/Authorization Summary 
Source of Funds 
There is no funding request as part of this authorization. Funding for the associated costs is 
included in the annual Environmental Remedial Liability (ERL) authorization. The costs are also
partially reimbursed by our partners and are eligible for state grant recovery when it is available. 
ECONOMIC IMPACTS AND BUSINESS PLAN OBJECTIVES: 
As a signatory on the Order, the Port is legally obligated to do this work as directed by EPA and
Ecology. The Port continues to carefully control costs associated with the effort to minimize
overall economic impact. 
STRATEGIC OBJECTIVES: 
This work supports the Century Agenda goal of being the greenest, most energy efficient Port in
North America by moving toward cleanup of the Lower Duwamish Waterway. Meeting our
obligation for this cleanup is a critical component of the Green Gateway strategy of meeting our
legal obligations. 
ENVIRONMENTAL SUSTAINABILITY AND COMMUNITY BENEFITS: 
Elimination of unacceptable levels of environmental risk caused by the presence of contaminants
in soil, groundwater and sediment is not only required by state and federal law, it reflects our
commitment to  environmental stewardship, from the perspectives of both the surrounding
communities and the customers that we serve. These detailed studies arethe critical first step for 
EPA and Ecology to create a cleanup plan for the LDW. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
1.  Undertake a full procurement process to enter into a new contract to replace the existing
contract. Given that this phase of the project, as well as the originally solicited scope of work
is almost complete, the consultant in place is deeply familiar with all of the studies and the
associated reports since they have produced them. Replacing the contr actors at a time when
studies and analysis are nearly complete would impair getting the work done in a timely, 
accurate fashion, and almost certainly result in a failure to meet regulatory deadlines and

resultant EPA enforcement action. This could also impact our cost-sharing partners, exposing
them to enforcement action and additional cost to procure and bring new consultants up to
speed on the projects. Under the existing MOA, our partners would have to agree on the
consultant performing this work. It is highly likely that they would not accept this approach. 
This is not the recommended alternative.
2.  Conduct the activities using Port resources, without outside consultant assistance.  The Port
does not have sufficient staff resources and expertise to conduct these environmental 
management tasks without consultant and laboratory support. Under the existing MOA,
partner'sstaff costs are not eligible for reimbursement, nor is there a mechanism in place to
obtain reimbursement for Port resources used. This is not the recommended alternative. 
3.  Amend the existing contract by adding $2,000,000 to the total contract value. This is the
recommended alternative.
