SUBJECT:  Environmental Monitoring and Hazardous Waste Construction Support Services
Indefinite Delivery, Indefinite Quantity (IDIQ) Professional Services Agreement 
Amount of this request:                       $0 
Total requested project cost:          $6,000,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to execute two professional
services  IDIQ  contracts  to  perform  Environmental  Site  Support  Services  (environmental
monitoring  and hazardous waste support to construction projects)  with a total value of
$6,000,000 and a contract ordering period of five (5) years. No funding is associated with this
authorization. These IDIQ contracts will replace two existing contracts executed in 2018 that will
expire in 2023 at the end of their 5-year ordering period. 
EXECUTIVE SUMMARY 
The Aviation Environmental Compliance team proposes to advertise and select two qualified 
firms to provide environmental site support services. The two IDIQ contracts would provide 
environmental construction monitoring, hazardous waste compliance and site assessments for
environmental due diligence to the Airport’s Capital Improvement Program (CIP), daily
operations, planning and development initiatives, and other strategic interests. The contracts
would also be used by other Port Divisions as needed. 
IDIQ contracts provide the Port with the flexibility to meet business requirements as they arise
by issuing individual Service Directives to accomplish tasks within the general, pre-defined scope
of work on an as-needed basis for a fixed period of time and a maximum contract amount. The
funding for these service directives will come separately from either annual operating budgets
or individual project authorizations.

Meeting Date: May 23, 2023 
JUSTIFICATION 
This contract will enable the Port to perform environmental construction monitoring, hazardous 
waste management compliance and environmental assessment support. Management of waste
consistent with the Port’s operational and construction monitoring work plans as well as federal
and state regulations minimizes construction delays, limits adverse environmental impacts,
reduces the Port’s exposure to unacceptable liability, and avoids enforcement actions.
Competitively bid IDIQ contracts are a widely used public sector contracting tool, consistent with
the Port’s General Delegation of Authority and governed by Central Procurement Office (CPO)-1
policy.
The contract will be procured according to CPO-1 procedures for Category III procurement. The 
Port will advertise and issue a request for qualifications (RFQ) that includes a Women and
Minority Business Enterprise (WMBE) goal of sixteen percent (16%) for each contract awarded. 
An evaluation of the level of outside services required versus Port staff support was performed
and is detailed in the Alternatives and Implications Considered section below. This evaluation 
considered cost as well as staff availability, impacts to work schedules, and level of in-house 
expertise. The evaluation concluded that ongoing environmental site support services will be
most effectively met through continuing with a combination of existing Port staff supplemented
by IDIQ contract support. 
Diversity in Contracting 
The scope of work document for this contract has been provided to the Diversity in Contracting
Department, and they are conducting an evaluation to recommend women- and minority-owned
business enterprise (WMBE) aspirational goals and inclusion plans. The aspirational goals
recommended by the Diversity in Contracting Department will be applied to both contract
awards. 
DETAILS 
Port environmental staff is on-call 24/7 and responds as needed to monitor and coordinate 
environmentally related events, all spill response actions, and discovery of unanticipated
contamination during construction and other Port activities. Annually, the Port manages
hundreds of thousands of pounds of contaminated soil, hazardous waste and other regulated
materials as well as responds to other environmental emergencies. A major portion of this work
is  monitoring  construction  activities for  environmental  contamination  caused by historical
operations and current-day spills of hazardous materials. In many cases, contaminated soils at
these sites present no risk to human health or the environment while in place or below
pavement. However, that same contaminated material must be properly managed and disposed
of in accordance with federal and state requirements once excavated and removed from the site.

Meeting Date: May 23, 2023 
In 2002, an environmental construction monitoring work plan was developed to document the 
coordination and oversight activities related to the discovery, evaluation, and disposal of
contaminated materials encountered during Airport construction projects. This work plan has
been approved by the Washington State Department of Ecology and is implemented as evidence
that the Port is properly managing all contamination discovered and that known on-site 
contamination  is not causing  harm  to  human  health  or the environment.  Continued
implementation of this plan decreases the potential for independent cleanup projects that
drastically delay and interfere with our capital improvement program. In addition to properly
managing contaminants on-site, environmental construction monitoring ensures the Port
properly disposes of contaminated material, preventing significant additional costs and cleanup
liability. 
In addition, Airport operations and maintenance activities generate hazardous waste which must
be managed appropriately. These wastes include maintenance supplies, garden pesticides,
building materials containing PCB’s, mercury, and lead, underground storage tanks,  and
containers of unknown contents. Each of these materials requires special management to comply
with the rules of multiple regulatory agencies.
Acquisitions of property previously used for residential, commercial, and industrial purposes also
can contain hazardous wastes that need to be disposed of properly. These acquisitions require
environmental assessments and other technical support services to determine if historical
contamination is present and how the site should be properly characterized to meet
environmental due diligence standards. 
The current Environmental Site Support Contract has been in place since 2018 and will expire at
the end of 2023 when the 5-year ordering period ends. 
Scope of Work 
The scope to be conducted under this contract includes: 
(1)   Environmental construction monitoring of capital and operational projects for facility
construction, repair, decommissioning, and other subsurface construction projects. 
(2)   Hazardous waste management support to implementation of the Hazardous Materials
Reduction and Stormwater Pollution Prevention programs. 
(3)   On-call response support services to construction and non-construction related spills,
investigation and assessment of underground storage tanks, and other pollution
generating activities. 
(4)   Site management under various regulatory authorities. 
(5)   Analytical laboratory and data coordination. 
(6)   Environmental project cost estimation. 
(7)   Graphics Production; and 
(8)   Support of Port cost recovery.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Four alternatives for meeting the Airport’s Environmental Site Support Services requirements
were evaluated. The alternatives evaluated methods of performing environmental construction 
monitoring tasks through contracted services, Port staff, construction contractor, or combination
of all three. Annual costs for each alternative were evaluated based on the anticipated demand
for environmental construction monitoring during a construction season. 
Although the level of required services may vary year to year, the relative costs for each
alternative was shown to remain the same and therefore did not affect the evaluation of the
alternatives presented below. Hazardous waste compliance and site assessments must be
performed through contracted services due to technical expertise needed for these tasks. Cost 
for these tasks was therefore the same in each alternative. 
Alternative 1 – Environmental Monitoring & HW Support Services completed through IDIQ
contract only: 
Cost Implications: Estimated Annual Costs: $1,261,000. 
Pros: 
(1)   Contractor only gets paid for work performed; no payment is given for being on-call. 
(2)   Does not require additional Port staff. 
(3)   Provides flexibility of contracted work force. 
(4)   Provides consistent reporting and documentation. 
(5)   Direct  control  of  contamination  and  low  potential  for  compliance  violations  or
environmental liability. 
Cons: 
(1)   Increased costs as compared to Alternative 3 and 4. 
This is not the recommended alternative. 
Alternative 2 – Environmental Monitoring & HW Support Services performed by Construction
Contractor only. 
Cost Implications: Estimated Annual Costs: $1,425,000. 
Pros: 
(1)   Reduces AV/ENV staff costs for contract administration.

Meeting Date: May 23, 2023 
Cons: 
(1)   Increases environmental liability due to lack of direct control of waste designation. 
(2)   Increases AV/ENV staff time to track, compile and manage contractor reports. 
(3)   Prime contractor would charge premium up to 25% markup to manage these services 
under force account. 
(4)   Potential overpayment for mischaracterized soil. 
(5)   Costs greater than the other alternatives. 
This is not the recommended alternative. 
Alternative 3 – Environmental Monitoring & HW Support Services completed by Port Staff only. 
Cost Implications: Estimated Annual Costs: $980,600.

(1)   Reduces AV/ENV staff costs for contract administration. 
(2)   Provides Port workforce that can increase or decrease service level of effort as needed. 
(3)   Provides trained Port workforce with specific technical expertise. 
(4)   Provides consistent reporting and documentation. 
(5)   Direct  control  of  contamination  and  low  potential  for  compliance  violations  or
environmental liability. 
Cons: 
Servicing peak seasonal demand requires hiring multiple additional full-time employees resulting
in unutilized labor through the majority of the year.
This is not the recommended alternative. 
Alternative 4 – Environmental Monitoring & HW Support Services completed by IDIQ Contract
and Port Staff. 
Cost Implications: Estimated Annual Costs: $1,000,000. 
Pros: 
(1)   Provides contracted and Port work force that can increase or decrease service level of
effort as needed. 
(2)   Utilizes existing trained Port staff with specific technical expertise. 
(3)   Direct  control  of  contamination  and  low  potential  for  compliance  violations  or
environmental liability. 
(4)   Provides consistent reporting and documentation. 
(5)   Reduces AV/ENV staff costs for contract administration. 
Cons: 
(1)   Coordination is required between Port Environmental Construction Manager and

FINANCIAL IMPLICATIONS 
The contracts will have a total not-to-exceed amount of $6,000,000. The Port will authorize work
under individual Service Directives as specific work tasks are required and funding for that work
is authorized by the Commission.
Individual Service Directives will be negotiated and processed before any work is performed.
Service Directives, consisting of a scope, fee agreement and schedule, will not be established
until the project has been approved in accordance with the General Delegation of Authority to
the Executive Director and Policy EX-2. There are no guarantees that the Port will initiate any
Service Directive or that any related projects will be authorized by the Port Commission. The Port
will not issue service directives in excess of the $6,000,000 combined contract dollar value. 
Contract payments are to be included in the annual operating budget as specific line items in the
Aviation Operations Department budget.
