ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to 1) design and prepare
construction documents for the 2015 Fuel System Modifications project at Seattle-Tacoma
International Airport (Airport) in the amount of $188,000 for this project. The total estimated
project cost is $2,069,000. 
SYNOPSIS 
This 2015 Fuel Systems Modifications project will add or modify fuel pits as needed 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 project aligns with the Port's Century Agenda's strategic objectives to
advance this region as a leading tourism destination and business gateway as well as to be the
greenest and most efficient port in North America. This project is included in the 2015  2019
capital budget and plan of finance. 
BACKGROUND 
Current airline activity growth is pushing gate operations to its capacity requiring the activation
of previously dormant gates, revised aircraft parking layouts, and improved  flexibility, 
maximizing the range of plane types accommodated at individual gates. To enable continued 
hydrant fueling of aircraft, we must modify and install new fuel pits to fulfill requests for aircraft
gates from airlines. This project will modify the fuel system so that fuel pits are properly located
at the gates for the use of hydrant fueling.

Airport staff has identified the need for new fuel pits at Gates A4 and B6. During design, the
need for other fuel system modifications at other locations may be identified.  Potential
modifications have already been identified at Concourse A and the South Satellite. 
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 already crowded ramp area. 
It is anticipated that the design will be accomplished with in-house staff. 
Project Objectives 
As airline activity continues to grow, this project will improve utilization of gates while
remaining constant with using hydrant fueling over truck fueling whenever possible. Project
objectives are as follows: 
The installation of a new fuel pit at Gate B6 
The installation of a new fuel pit at Gate A4 
The completion of any additional fuel system modifications confirmed necessary before
the design is complete. 
Scope of Work 
The scope of work is fuel system modifications to support aircraft gate operations. The work
includes installation of a new fuel pit at Gate B6 to accommodate revise aircraft parking layout
on Concourse B, installation of a new fuel pit to improve gate flexibility at Gate A4, and fuel
system modifications or additions at other locations that are identified as being needed during the
design phase. Due to the dynamic nature of the airline industry and aircraft gate operations, fuel
system modifications that may be needed in 2015 are not fully known. However, potential need
for modifications has already been identified at Concourse A and the South Satellite. Fuel system
modification is a specialized type of work and the inclusion of as much work into a single
contract results in cost effectiveness.

Budget Status and Source of Funds 
This project, C800692, was included in the 2015  2019 capital budget and plan of finance with
a budget of $1,100,000. The budget increase will allow flexibility to address additional fuel
system modifications. 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 include the Airport Development Fund and future revenue bonds. The Port plans to issue
bonds in 2015 to fund multiple projects.

Lifecycle Cost and Savings 
The fuel system at Seattle-Tacoma International Airport is leased to and maintained by SEATAC
Fuels, LLC, an airline consortium. The Port intends to negotiate an amendment to the lease to
add these new fuel pits to the lease. 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. 
STRATEGIES AND OBJECTIVES 
The 2015 Fuel System Modifications project supports the Port's Century Agenda's strategic
objectives to advance this region as a leading tourism destination and business gateway as well
as to be the greenest and most efficient port in North America. This project also supports the
Aviation Division's strategic goals of operating a world-class international airport, providing an
extraordinary customer service, and being a model of environmental innovation for the region
and industry.
TRIPLE BOTTOM LINE 
Economic Development 
The project creates short-term construction jobs, allows the Airport's business partners to expand
and streamline their operations, and maximizes gate utilization for future expansion of air service
at the Airport. 
Environmental Responsibility 
This project reduces vehicle emissions at the Airport by facilitating fueling from the fuel system
and reducing the number of fueling trucks driving on the airfield. 
Community Benefits 
This project supports safer working conditions on the airfield by minimizing traffic on the
Airport roadways and around aircraft. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1) Do nothing. Continue truck fueling at Gate B6 and do not accommodate 767's at
Gate A4 to keep truck fueling at a minimum. Truck fueling has been approved as an interim
solution but is not the preferred long-term method. Truck fueling takes up valuable space on the
apron with large trucks and increases traffic on the ramp. This is not the recommended
alternative. 
Alternative 2) Install fuel pits that work with the new aircraft parking realignments at Gate B6
and that improve gate flexibility to accommodate 767's at Gate A4. Also accommodate
additional fuel system modifications that are confirmed necessary before design is complete.
Anticipated fuel pit work on Concourse A and South Satellite has been identified but the scope is
not limited to those areas. Hydrant fueling is the safest and least environmentally detrimental
option for fueling aircraft. Fueling from pits adds space on the ramp by removing large refueling
trucks, reduces traffic on the ramp and also provides for potentially reduced turnaround times
compared to truck fueling. This is the recommended alternative.
