FROM:   Mike Ehl, Director, Airport Operations

SUBJECT:  2016 Fuel System Modifications (CIP #C800692) 
Amount of This Request:     $4,492,000      Source of   Airport Development Fund 
Funds: 
Est. Total Project Cost:      $4,680,000 
ACTION REQUESTED 
Request Commission authorization for (1) the Chief Executive Officer to advertise and execute a
construction contract to construct fuel system modifications in support of gate operations at
Seattle-Tacoma International Airport in an amount not to exceed $4,492,000 and to use Port
crews in support of the project and for removal of regulated materials; and (2) to increase the
project scope for additional fuel system modifications. 
SYNOPSIS 
This 2016 Fuel Systems Modifications project will add fuel pits to support aircraft gate
operations. The use of the hydrant fueling system to fuel aircraft, rather than fueling by truck,
improves safety, reduces air pollutant emissions, and improves efficiency by reducing fueling
time.
The total value of this authorization request is $4,492,000 of an estimated total project cost of
$4,680,000. Since the design authorization on November 11, 2014, staff has identified five
additional fuel pits that are needed to support modifications. This increase in scope (from the
original four fuel pits), together with a proposed construction method that is more costly but will
substantially reduce the time the fuel hydrant system is out of service, drive a budget increase of
$2,611,000. 
BACKGROUND 
Current airline growth is pushing gate operations to its capacity requiring revision of aircraft
parking layouts to improve flexibility and maximizing the range of aircraft types accommodated
at individual gates. To avoid interference with other vehicles servicing the aircraft, the desired
distance from the fuel pit to the aircraft is not more than 25 feet. Revised gate layouts require
modification of the existing fuel system by adding new fuel hydrants to continue hydrant fueling

of aircraft. Fuel system modification is a specialized type of work and the inclusion of as much
work into a single contract results in cost effectiveness. 
Four fuel pits were originally identified as being needed for gate modifications. Airport staff has
since identified five additional pits for a total of nine new fuel pits needed to provide hydrant
fueling in a maximized aircraft parking layout. This is especially important as we get closer to a
time of multiple gate outages due to major construction projects. 
A hot-tap is a less intrusive construction method that avoids cutting into the fuel main and
reduces shutdown time to the fuel system. This construction method is planned to be used on the
project to minimize impacts to the gates and shorten the periods of time that fuel system sections
are out of service.  Port staff anticipate the fuel system shutdown to require approximately 12
hours with this method versus several days. Consultant support will be used to support this
approach, which is new to the Port. 
Port Construction Services (PCS) may be utilized to support regulated material management
(RMM) of potential asbestos items encountered during construction. 
PROJECT JUSTIFICATION AND DETAILS 
This project is necessary to meet the Aviation Division's goals of ensuring safe and secure
operations, avoiding increased air pollutant emissions from fuel trucks, and anticipating and
meeting the needs of airlines in support of activity growth. The Port of Seattle and airlines made
a decision in the past to install a hydrant fueling system and discontinue truck fueling whenever
possible in order to improve safety and reduce emissions on the airfield. Hydrant fueling also
reduces the fueling time as well as the amount of traffic on the ramp area. 
Project Objectives 
Project objectives are as follows: 
Installation of fuel system modifications to improve gate operations 

Scope of Work 
This scope of work is associated with fuel system modifications to support aircraft gate
operations. The work includes installation of a new fuel pits at approximately 9 gate locations to 
accommodate aircraft parking and improve gate flexibility.

Budget Status and Source of Funds 
This project, C800692, is included in the 2016  2020 capital budget and plan of finance with a
budget of $4,194,000, reflecting the increased scope. The budget increase of $486,000 is due to
the use of the hot-tap methodology and additional design development allowance driven by this
change.  The budget increase will be transferred from the Aeronautical Allowance CIP
(C800404) resulting in no net change to the Airport's capital program. The funding sources will
be the Airport Development Fund.

recovered directly from the airline fuel consortium. 
The fuel system at Seattle-Tacoma International Airport is leased to and operated by SEATAC
Fuels, LLC, an airline consortium. The Port will negotiate an amendment to the lease to add

these new fuel pits to the lease as it has with other fuel pits added in the past. If successful, the
consortium would pay for the operating and maintenance costs of these new pits and would pay
additional rent to the Port equivalent to the annual amortization of the capital costs. Thus, under
such a lease amendment, there would be no impact to passenger airline CPE. 
Lifecycle Cost and Savings

STRATEGIES AND OBJECTIVES 
The 2016 Fuel System Modifications project supports the Century Agenda goal to advance this
region as a leading tourism destination and business gateway by meeting the region's air
transportation needs and encouraging the cost-effective expansion of domestic and international
passenger service. This project also supports the Aviation Division's strategic goals of operating
a world-class international airport, providing extraordinary customer service, and being a model
of environmental innovation for the region and industry. 
One of the Century Agenda goals is to use the Port's influence as an institution to promote small
business growth and workforce development. Although some of this work may be specialized,
Port staff will coordinate with the Office of Social Responsibility to identify potential
opportunities within the scope of work for small business utilization. 

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1) Do not add hydrants, increase truck fueling over time as gate layouts are 
modified. 
Pros: 
Under this option there is no near-term capital investment for the
Airport 
Cons: 
The airlines and fuel service providers would need to purchase
additional fuel tanker trucks.
Aircraft turn times (time between landing, servicing and then
departing) would be impacted by slower fueling rates and impacts of
fuel tankers on other vehicles and equipment servicing aircraft.
Traffic on the ramp would increase, especially between the South
Satellite and the current fuel rack which is north of the North Satellite.
The airport would need to identify ramp storage areas (already in high
demand) for fuel trucks and maintenance facilities.

Increase in air emissions as a result of fuel trucks deliveries.
This is not the recommended alternative. 
Alternative 2) Install new fuel hydrant pits at gates where aircraft parking layouts have been 
optimized for more efficient gate utilization.
Pros:
Hydrant fueling increases safety on the airport ramp. 
Hydrant fueling is more efficient than other fueling methods. 
The cost of adding new fuel hydrant pits is fully recovered through the
fuel consortium lease.
Minimize air emissions by avoiding fuel truck deliveries. 
Cons: 
Temporary gate closures during construction. 
This is the recommended alternative.
