SUBJECT:  Unified Pest Management (UPM) Contract Increase 
Amount of this request:               $5,550,000 
Total estimated project cost:           $5,550,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to: (1) increase the value of the
current Unified Pest Management contract at Seattle-Tacoma International Airport by $550,000 
to continue current services from January 2019 through June 2019; (2) competitively bid and
execute a new 5-year follow-on contract (commencing on or about July 1, 2019, and continuing
through June 30, 2024) for a base year and additional four 1-year options for an estimated
amount of $5,000,000. 
EXECUTIVE SUMMARY 
Because of the number of people using the facility and the provision of food service through
the Airport Dining and Retail program, pest control at the Airport is a priority. The Portoperated
UPM program is designed to centralize pest reporting and coordinate an appropriate
control response that addresses the rodent sightings in restaurants and the terminal, focusing
on the cause of rodents rather than just their presence. The pest control program at the Airport
has grown substantially since the contract was awarded in 2016. In 2017, there were 231 safety
calls related to pests. I n 2018 to date we have reached 745 calls. This request will provide the
necessary funds to support the current program. Continuity of services is vital for protecting 
passenger and employee health and safety. 
Funding for the original $1.2 million contract will be expended shortly after the first of the year,
two years earlier than anticipated. The increased rate of spending is due to new 24/7 coverage
and use of new pest control technology. UPM is spending approximately $73,000 more a month
than originally budgeted ($20,000). The total requested amount is $5,550,000 for: 1) the
increase to the existing contract, $550,000; and 2) for funds related to the follow-on contract; 
$4.8 million plus $200,000 contingency fund. We anticipate needing the same level of service
for 2019 and 2020 to regain control of rodent populations. By 2021, control efforts will have

been effective long enough to prevent a rebound effect by the high reproduction rate. At this
time the budget would decrease by 20 percent and be subject to contractual increases in 2022
and 2023. 
We expect that a new RFP will be advertised in spring and awarded in June to begin services in
July 2019. We project that as pest numbers are driven down, UPM will transition to more
preventive measures compared to the mostly reactive current measures. UPM effectiveness
will be re-evaluated at this time based on the increased passenger volumes, increased square
footage, and compliance of higher sanitation standards. 
JUSTIFICATION 
Increased passenger volume and construction activity at Sea-Tac Airport have driven the need
for  expanding  pest  management services  to maintain  a  healthy  and  safe  environment. 
Construction across the Airport campus, specifically the new International Arrivals Facility,
Baggage Optimization, and Central Terminal Projects,  likely disturbed established habitat,
causing pests to seek new habitat.  In addition, the significant increase in passenger traffic
through the Airport during the past five years (enplanements up 40 percent since 2013) has led
to increased trash and rodents multiplying more rapidly. The currently contracted pest control
and technical support efforts were based on lower passenger numbers, fewer trash/sanitation
concerns,  fewer concessionaires,  and lower pest activity. These efforts  are  now  proving 
insufficient to meet current need. 
Port staff, along with a pest management consultant and its contracted pest control service
provider, has worked aggressively over the past six months to respond to this issue. The Unified
Pest Management Working Group met again to reevaluate and reprioritize Port and tenant
responsibilities. Under this Port program the Port provides services to the tenant and airline
member spaces on a cost recovery basis. The UPM tariff is also being reevaluated. The primary 
pest control benefit is UPM addresses the space around the problem area rather than just the
space of the tenant that reported the issue even though it may not be the source of the
problem. Additional efforts include increasing contractor support to 24/7, new interior baiting
strategies, additional trapping efforts, smart technologies and contracting an independent 
consultant. It is critical th at the Port continue this effort to ensure the health and safety of the
traveling public and Airport employees. The Port's waste management programs have been
updated to minimize pest access to these resources. The Port is also working on a tenant
education program so sanitation standards are better defined and enforced. Staff has also
recognized that meeting our airport-wide pest management goals requires greater partnership
with tenants and the development of new airport-wide sanitation practices. The requested
funds will allow efforts already underway to continue through June 2019 when a new contract
will be in place.

COMMISSION AGENDA  Action Item No. 6e                                   Page 3 of 6 
Meeting Date: November 13, 2018 
DETAILS 
Prior to the implementation of the UPM program in 2013, airport tenants contracted their pest
control services independently, with little information available to the Port by which to
determine the type and magnitude of concerns the tenants faced or what kind of control
methods their contractors were using to address them.  Today the UPM program has 100%
enrollment of all concessionaire and airline tenants. UPM gives the Port the ability to track all
pest reports at the airport to better manage the needed actions. UPM is able to work with
many airport departments (Airport Dining and Retail, Port Construction Services, Aviation
Maintenance) to  better remediate pest issues by addressing items that contribute to the
problem, such as small openings that need to be sealed off to prevent pest access. Pest issues
are reported to UPM through a safety hotline. Call-in data are used to identify problem areas,
determine best practices and monitor contractor response times. Consequently, the Port has
been successful in tracking and identifying where pest hotspots are and what contributing
factors need to be addressed promptly. 
In early 2018, it was necessary for the pest contractor to respond to many more emergency call
outs rather than the proactive work they had been doing. By May 2018 it became clear that one
technician per day could not handle all pest management needs and 24/7 coverage was
justified. With a rise in pest complaints/sightings by the public earlier this year and an increase
of complaints to King County Public Health and Washington Department of Labor and Industry
it was urgent that the contractor increase resources and technologies immediately, raising the
cost of the contract well past its original scope and budget. 
Rodent numbers are expected to stabilize then decline in the future. The existing level of effort
is required to finish driving rodent numbers down, given the tenant sanitation training program
is  not  fully  implemented  and  the  new  spaces  such  as  the  D-Annex,  North  Star  and  the
International Arrivals Facility will add spaces that will soon need UPM services. The UPM goal is
to reach greater than 90 percent eradication to prevent another uptick due to the high
reproduction rate of rodents. 
UPM Efforts to Date 
Equipped more areas above drop ceilings with additional control methods 
Identified and expanded efforts in interstitial spaces between the ceilings and the roof on B,
C, and D Concourses 
Pest contractor and Port Construction Services have been sealing off entry points in spaces
to prevent access 
Aviation Maintenance is securing/replacing ceiling tiles 
More intensive sanitation audits in of tenant spaces have begun 
Hired an independent consultant to evaluate the Port's UPM program as well as its pest
control contractor 
Provided guidance and training on best practices to reduce opportunities for pests

Scope of Work 
The updated scope of work requires the contractor to provide 24/7 coverage and additional use
of technologies to help monitor rodent movements and to more efficiently remove them from
the airport. These additional resources will maintain the quick response times to urgent events
called into the safety hotline at all hours and will help technicians access the hard-to-reach
interstitial spaces above ceilings that are crucial for effective rodent management. When not
trapping or responding to callouts, technicians can now use their time sealing off access points,
inspecting vendor equipment, and addressing sanitation concerns. These technicians will also
monitor new construction sites for pest activity prior to construction and verify that new
construction has no access points for rodents. 
Schedule 
The budget increase for the existing pest control contract will commence upon Commission
approval. An RFP for the follow-on contract will be issued on or about March 1, 2019 and
awarded no later than June 30, 2019. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do not increase the existing contract. The current contract will run out of funds 
in December 2018. Pest services would end until there was time to get a new contract in place,
which could take several months. 
Cost Implications: $0 
Pros: 
(1)   None. 
Cons: 
(1)   The current Pest control contract would end, pest numbers would increase and the
health and safety of  passengers and those working at the airport would be
compromised. 
(2)   The Port will receive more notices from King County Public Health and Washington
Department of Labor and Industries regarding pest-related complaints. 
This is not the recommended alternative.

Alternative 2  Allow tenants to contract their own pest control to meet increasing rodent
numbers. (This has been done before and rodent numbers/pressures could not be tracked or
measured.) 
Cost Implications: $0 
Pros: 
(1)   None. 
Cons: 
(1)    Pests could compromise the health and safety of passengers. 
(2)    The Port will lose oversight of pest issues and the ability to identify root causes and
the control methods that independent contractors are using. 
(3)   Pest  sightings  and  concerns  from  tenants  and  the  public  will  increase  thereby
jeopardizing the reputation of the airport. 
This is not the recommended alternative. 
Alternative 3  1) Increase the current Unified Pest Management Budget immediately through
June 2019; and 2) Competitively bid a 5-year follow-on contract starting July 1, 2019. 
Cost Implications: $5,550,000 
Pros: 
(1)   Sustains the level of rodent abatement currently in place until we are able to bid a
new contract July 2019. 
(2)   Airport will maintain oversight of pest control actions taking place with all required
data to make the best management decisions in correcting issues. 
Cons: 
(1)   None. 
This is the recommended alternative. 
FINANCIAL IMPLICATIONS 
The annual cost for this contract is included in the operating budget. Under the existing fiveyear
contract of $1,200,000, the 2018 budget included $265,000. Based on the increased level
of service for 2018, the Port anticipates spending approximately $700,000.  The preliminary
2019 budget anticipates spending $1,055,000.
