TO:        Stephen P. Metruck, Executive Director 
FROM:    Michael Ehl, Director Aviation Operations

SUBJECT:  Unified Pest Management (UPM) Contract Increase 
Amount of this request:                         $7,000,000 
Increase since previous authorization:           $2,000,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to execute a new contract for an
estimated value of $7,000,000 for Unified Pest Management at Seattle-Tacoma International
Airport. This action requests increased contract authority compared to the $5,000,000 Unified
Pest Management authorization of November 13, 2018. 
EXECUTIVE SUMMARY 
This request is to increase existing authorization for the new Unified Pest Management
requirement prior to contract award. Commission previously authorized a 5-year contract
(commencing on or about July 1, 2019) for $5,000,000 consisting of a base year and four
additional 1-year options. 
In developing the solicitation the Port increased scope to include new airport facilities (e.g.,
North Satellite (North Star) and International Arrivals Facility (IAF), additional Cargo facilities,
increased technical support, and addition of a dedicated sanitation specialist to conduct regular
night sanitation audits of tenant spaces.   The drivers behind the additional scope were
identified in working group meetings.  Sanitation audits were identified as one of the greatest
needs to improve conditions to decrease future pest control needs. Further, the North Satellite
and IAF added significant square footage beyond the original estimate.  The cost for this
increased scope was not included in the original Commission action. 
Competitive price proposals submitted for the new contract reflected pricing higher than
anticipated.   The higher-than-anticipated pricing requires funding exceeding the amount
previously authorized by the Commission on November 13, 2018.

JUSTIFICATION 
In January 2019 Port staff issued a competitive pest control procurement that was approved by
Commission on November 13, 2018. The existing authorization request was estimated using
the actual Unified Pest Management contract that was in place in late 2018 after increasing
services, but prior to expanding the scope to include sanitation audits and airport growth. 
Based on received competitive price proposals, the requested funding authorization is
insufficient to execute a new contract for the full 5 years. Utilizing the average prices received
in response to the UPM RFP the current authorized funding amount of $5,000,000 will allow for
3 years of contract performance.  Additional funding authorization would be needed to allow
for 5 years of performance (see table below). This request for additional funding authorization
will allow contract performance for up to 5 years with sufficient contingency to address 
unforeseen pest issues resulting in increased contract costs (i.e.,  unforeseen 2018 cost
increases). Authorization does not stipulate the Port spend all funding authorized, only that the
Port will have sufficient funding for all 5 years of contract performance and will further be
prepared to mitigate any unforeseen circumstances if needed.

Increased passenger volume, construction activity, and building square footage at Sea-Tac
Airport will continue to drive the need for an intensive pest management program to maintain
a healthy and safe environment.  Sanitation challenges and pest access have been aggressively
addressed by the Port Unified Pest Management Working Group and the Port's pest control
contractor, but there is still much work to do to correct all conditions that support pest
populations and eliminate all rodent access. We expect to maintain a high level of service as
the airport continues to grow and will evaluate the program's effectiveness annually for
potential cost savings. The UPM Tariff was adjusted January 1, 2019 to provide cost recovery
for services rendered in tenant locations for tenants whose lease language directs the tenant to
pay for pest control services via tariffs (e.g., Airport Dining and Retail tenants), and the airlines
pay for their pest control services via Signatory Lease and Operating Agreement (SLOA). 
UPM will continue to transition to more preventive measures compared to the mostly reactive
measures previously employed. Preventive measures include routine sanitation audits, active
inspections of all interstitial spaces and wall voids, and sealing all access points.  Reactive

measures (such as trapping or baiting) only correct the symptoms (pests), rather than the
underlying issues (e.g., sanitation and pest access). UPM effectiveness will be re-evaluated at
the end of each contract year based on pest activity, increased passenger volumes, increased
square footage, and compliance of higher sanitation standards and updated Rules and
Regulations. 
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 Airport Dining and Retail and airline tenants. UPM gives the Port the ability to
track all pest reports and activity at the airport to better manage the needed actions and
oversee pesticide use. UPM is able to work with many airport departments (Airport Dining and
Retail, Port Construction Services, Aviation Maintenance, etc.) to better remediate pest issues
by addressing items that contribute to the problem, such as inadequate sanitation or 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 assist in identifying problem areas and
monitoring contractor response times. Consequently, the Port has been successful in tracking
and identifying pest hotspot locations by using call-in data combined with pest data collected
by the vendor (e.g., rodent captures, bait consumption, and activity), 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 and prudent. With a rise in pest complaints/sightings by the public in early 2018 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. 
For the areas serviced today, rodent numbers are expected to stabilize then decline under the
higher level of control efforts and the more recently implemented sanitation audits. The
existing level of effort is required to reach greater than 90 percent eradication, our goal to
prevent another population uptick due to the high reproduction rate of rodents. Concurrently
the Port will audit tenant spaces to further improve sanitation and seal off all pest entry points.
Sanitation audits have been added to the scope of the new pest control contract. Tracking callin
data,  pest  data,  and  condition  data  (collected  from  sanitation  audits  and  other  Port
inspections) will allow the Port to more efficiently allocate resources to eliminate conditions
conducive to pests. The goal is to eventually reduce costs of the UPM program over time even
with additional building square footage over the next 5 years.

Meeting Date: April 23, 2019 
UPM Efforts to Date 
Created Port UPM Working Group to focus on identifying and correcting pest-related issues 
Increased pest control vendor presence to 24/7 
Equipped more areas above drop ceilings with additional control methods 
Identified and expanded efforts inside the interstitial spaces between the ceilings and the
roof that support hidden reservoir rodent populations 
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 of lease spaces 
Hired an independent consultant to evaluate the Port's UPM program and the Port's pest
control contractor 
Provided guidance and training on best practices to reduce opportunities for pests 
Updated construction specifications to seal all access points during construction activities 
Scope of Work 
The scope of work requires the contractor to provide 24/7 coverage and additional use of
monitoring and capture technologies to help identify and 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
continue to 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. The new contract's scope of work includes performing night sanitation audits, more
square footage, and ornamental pest control so that all pest issues can be resolved using the
same vendor. 
Schedule 
The UPM RFP is being evaluated and the contract will be executed before July 2019.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do not approve request for increased funds associated with the updated scope
of work and its related costs 
Cost Implications: At minimum, 6 months' time frame and +/- 500 staff hours, estimated 
$30,000 to procure a new UPM contract. 
Pros: 
(1)    Opportunity to review qualified pest control vendors, prices, and technologies sooner
than under other alternatives. 
Cons: 
(1)   The new contract will run out of funds well before the proposed 5-year contract term. 
Utilizing the average proposal price submitted in response to the UPM RFP, the Port
will  only  be  able  to  fund  3  of  the  potential  5  years  of  performance  previously
authorized by Commission.  If additional funding is not authorized, there will be a 
need to return to Commission for additional authority and initiate a new UPM
procurement (see table on page 2) up to 2 years earlier than would otherwise be
required if additional funding authorization is obtained now. 
(2)   Any gap in pest control service will compromise the integrity of the UPM program by
allowing pest numbers to again increase unmitigated thereby jeopardizing the health
and safety of the airport's occupants and the airport's reputation. 
This is not the recommended alternative. 
Alternative 2  Allow tenants to contract their own pest control to meet increasing rodent
numbers. 
Cost Implications: Incalculable/Unknown 
Pros: 
(1)    None 
Cons: 
(1)    This was the procedure prior to the creation of UPM in 2013 and pest numbers and
controls activities, including pesticide application at the airport, could not be easily
monitored. 
(2)    Pests could compromise the health and safety of passengers. 
(3)    The Port will lose control over coordinated pest remediation treatments and its ability
to identify and correct root causes. 
(4)   Pest  sightings  and  concerns  from  tenants  and  the  public  will  increase  thereby
jeopardizing the reputation of the airport. 
This is not the recommended alternative.

Meeting Date: April 23, 2019 
Alternative 3  Increase the authorized amount to fund the full 5-year term of the new contract
commencing on or about July 1, 2019. 
Cost Implications: $2,000,000 (for total contract authorization of $7,000,000) 
Pros: 
(1)    No interruption of service. 
(2)   Accommodates increased airport growth. 
(3)   Airport  will  maintain  oversight  of  pest  control  actions  which  is  necessary  for
monitoring and reducing the use of pesticides, as an example. 
(4)   The Port will have access to all UPM data to make the best management decisions and
track successes and emerging issues. 
(5)   No  need  to  re-procure  within  the  next  5  years,  reserving  CPO  and  Wildlife
Management resources for other activities. 
(6)   Though tenant costs (tariffs and rates used for UPM cost recovery) may increase and
will continue to be high for the duration of the contract term, they are likely to be
even higher if the Port fails to address all conditions conducive to pests through
increased pest control efforts. The current procurement  consists of a base year and
four additional 1-year options (potential 5-year contract).  The long-term goal is to
reduce costs by eliminating conditions conducive to pests and by maintaining a low
pest population. 
Cons: 
(1)    Tenant costs (tariffs and rates used for UPM cost recovery) may increase to recover
UPM costs and will continue to be high for the duration of the contract term. 
This is the recommended alternative. 
FINANCIAL IMPLICATIONS 
The preliminary 2019 budget anticipates spending $1,055,000.  Contingency will be needed to
execute the new contract and the 2020 budget will be adjusted. The UPM Tariff was adjusted
January 1, 2019 to provide cost recovery for services rendered in tenant locations and the
airlines pay for their pest control services via SLOA.
