ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to: (1) advertise and execute
a construction contract for Phase 1 of the Ground Support Equipment-Electrical Charging
Stations Project-Installation of Chargers; and (2) pre-purchase electrified ground support
equipment (EGSE) chargers for Phase 2 of the project. This authorization totals $16,200,000 
(including $200,000 expense) of the total estimated project cost of $30,700,000. 
SYNOPSIS: 
This request enables staff to continue to move forward on the project to enable the phase-out of
fossil-fueled vehicles such as baggage tugs and aircraft pushback tractors at Seattle-Tacoma
International Airport. The new electrified ground support equipment will be owned and operated
by the airlines. The Airport intends to install EGSE chargers throughout the passenger terminals
for airline use, which will help improve air quality, reduce the carbon footprint of the Airport,
reduce airline maintenance costs, and save fuel costs. It is estimated 20 chargers will power 40
EGSE vehicles. With full airline participation, a fuel savings of $2.8 million per year is
anticipated, with CO2 reduction of 10,000 tons per year (the equivalent of 1,700 cars being
removed from local roadways).
The overall EGSE program consists of the following three major components: 
Port Construction Services (PCS) has installed 20 chargers in a demonstration project and
Horizon Air is ordering EGSE equipment to replace its existing fossil-fueled GSE fleet.

Phase 1 will install approximately 124 chargers on Concourses C and D and the North
Satellite.
Phase 2 will install approximately 112 chargers at the remaining passenger terminals.
The entire program will install approximately 256 chargers throughout the Airport capable of
charging 512 pieces of GSE simultaneously. The total estimated cost of the project is $30.7
million. 
The previous Western Washington Clean Cities Coalition (WWCCC) $5 million grant for EGSE
vehicles is being revised so that the funds can be used to offset the cost of the charger
procurements. Alaska Air Group is utilizing approximately $1 million of the grant to assist with
its purchase of approximately 226 EGSE units. The remainder of the grant will be utilized to
offset the costs of procuring and installing the chargers in Phase 1. Additionally, staff is
pursuing anticipated Federal Aviation Administration (FAA) Voluntary Airport Low Emission
(VALE) program grants of up to $6 million for Phase 1 in fiscal year 2013, and up to $9 million
for Phase 2 in fiscal year 2014. Phase 1 design has been expedited to allow the Port and Alaska
Air Group to meet the dates for grant eligibility for the WWCCC grant. 
In March 2012, the airlines approved the full project in a Majority in Interest vote. Previous
Commission authorizations include $1.51 million on October 26, 2010, for preliminary design,
and $8 million on April 3, 2012, to install 20 chargers at the demonstration site, order charging
units, and design the installation. This project was included in the 2012  2016 capital budget
and plan of finance. 
BACKGROUND: 
Since 2005, staff has been working with the airlines towards installing EGSE equipment at the
Airport. In 2010, a WWCCC grant was approved for $5 million to offset the additional cost of
EGSE vs. fossil-fueled GSE. Staff has renegotiated the WWCCC interlocal agreement to extend
it until September 2013. Alaska Air Group will utilize approximately $1 million for EGSE
equipment and the Port will attempt to utilize the balance of the grant by September 2013. 
Currently, Washington law allows a waiver of state sales tax on the purchase and installation of
energy-saving equipment until 2016, which will save approximately $2 million in taxes for the
entire project. 
Project design and construction have been accelerated in order to meet grant funding deadlines.
Although this poses project risks, staff believes that these risks are manageable and that the Port 
should continue on this accelerated schedule. 
Design - The design is the multiple repetition of the same basic charger layout at various
locations. However, the compressed design schedule adds change order risk given the
amount of conduit being run from existing electrical rooms out to the charging stations, 
possible lack of information about the existing conditions along the route, insufficient
panel descriptions, and deletion of final detailed design review from the schedule. 
Advertising for bids - Going from 100% design to advertisement without a detailed
design review means there is a likelihood of addenda to the advertisement for bids on this
project and depending on the depth and breadth of information conveyed, this could lead

to a postponed bid date, thereby putting additional pressure on the compressed
construction schedule to meet the WWCCC completion date of September 2013.
Construction schedule - Should the project be delayed, the contractor may have to double
shift or work overtime (which may result in additional costs) in order to meet the grant
deadline for completion. Staff will assess that risk should the project encounter
unforeseen delays. As it is now, a good portion of the work will need to occur at night.
Operational coordination - As is typical for this type of project, all work at the stations
will require close coordination with airline operations with limited space, little flexibility, 
and tight windows of opportunity to complete the work, including electrical shutdowns
that could cause contractor delays. However, most of the work can be accomplished
without disrupting airline operations, so the coordination risk is small.
PROJECT JUSTIFICATION: 
Project Objectives: 
This project: 
Reduces carbon emissions 
Reduces fuel consumption by approximately one million gallons per year 
Reduces airline maintenance costs 
Uses available grant funding 
Takes advantage of Washington state sales tax waivers that expire in 2016 for the
project elements related to utilizing electrical power vs. fossil fuel 
PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
This project will ultimately install electrical chargers throughout the passenger terminal ramps.
The chargers and the long-lead electrical equipment will be pre-purchased by the Port and
delivered to contractors when needed.  PCS has installed 20 charging units on Concourse C as a
demonstration project for airline training as well as operational use. These units will be
energized on October 24th. Concurren tly, Horizon is converting their existing EGSE equipment
so that they can utilize the new chargers. The installation of the remaining charging units will
be done in two phases. Phase 1 will consist of the North Satellite, Concourse C, and Concourse
D. Phase 2 will upgrade two power centers and install chargers on the remainder of the Airport.

Budget Status and Source of Funds: 
EGSE Charging Stations CIP #C800335 is included in the 2012-2016 capital budget and plan of
finance with a budget of $14,410,000. The cost increase was covered by a corresponding
reduction in CIP #C102165, Aeronautical New Project Allowance, resulting in no net change in
the total Aviation capital budget. As described in the April 3, 2012, design and pilot-project
authorization memo, the budget increase was a result of the preliminary design efforts that
revealed: 1) that two power centers did not have sufficient capacity to support the additional
power requirements of the EGSE system on Concourse B and the South Satellite, and 2) that the
original estimate did not have the appropriate soft costs applied. The source of funds for this
project will be existing revenue bonds, FAA grants totaling up to $15 million, the WWCCC
grant of up to $4 million, and future revenue bonds.

STRATEGIC OBJECTIVES: 
Exhibit Environmental Stewardship through our Actions. 
Be the greenest and most energy efficient port in North America; Reduce air pollutants
and carbon emissions. 
The Port's purchase and installation of EGSE charging stations will promote and expedite carrier
adoption of EGSE vehicles such as electric pushback tractors and tugs. Implementation of
EGSE reduces emissions at the Airport. EPA considers electric vehicles the best alternative
vehicle fuel option for emission reductions.
ENVIRONMENTAL SUSTAINABILITY: 
The project will promote the use of energy efficient electric equipment, reduce use of fossil fuel,
and reduce greenhouse gas emissions by up to 10,000 metric tons of CO2. Sea -Tac's electrical
needs come from nearly 100 percent renewable sources providing air quality improvements both
locally and regionally. This project eliminates the need of up to one million gallons of fossil
fuel, resulting in a reduced demand for non-renewable natural resources. 
BUSINESS PLAN OBJECTIVES: 
Operate a world-class international airport by anticipating and meeting the needs of our
tenants, passengers and the region's economy 
Lead the airport industry in environmental innovation and minimize the Airport's
environmental impacts 
TRIPLE BOTTOM LINE SUMMARY: 
This project helps to clean the environment by reducing greenhouse gasses, creates short-term
construction jobs, and incorporates small business opportunities to encourage small business
participation in a major construction contract. 
This project helps the environment by reducing energy consumption at the Airport and allows
our business partners to expand their operations.

ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1: Do nothi ng. 
In the do-nothing scenario, the Port would let market forces determine the rate at which EGSE
implementation would occur. Staff have concerns that without promoting the use of EGSE, and
providing the necessary infrastructure for it, Sea-Tac may inadvertently condone the use of fossil
fueled GSE for an extended period. Specifically, as carriers invest in EGSE at airports with poor
air quality, their legacy fossil fueled equipment will be redeployed in areas that do not have
immediate air quality concerns such as Sea-Tac. 
Alternative 2: Port purchases and installs EGSE charging stations. 
The Port of Seattle proposes to purchase and install the necessary infrastructure for Sea-Tac
airline carriers to utilize EGSE. By providing EGSE charging stations, carriers are encouraged
to preferentially upgrade their GSE fleet with electric vehicles at Sea-Tac Airport. EGSE
provides significant financial benefit for carriers through fuel and maintenance savings. Because
EGSE do not have tailpipe emissions, Sea-Tac will be able to document and quantify air quality
benefits from the project as well. The fuel savings associated with an Airport-wide EGSE
program could reach one million gallons annually. This is the preferred alternative.
