This Request: $1,510,000               Source of Funds: Airport Development Fund 
Total Estimated Budget: $44,410,000       Jobs Created: NA 
Sales Tax Paid: $60,000 (this authorization) 
ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to: (1) prepare designs; (2)
authorize the use of Port work crews; and (3) execute and amend contracts for materials,
abatement, equipment, work, and services to move the EGSE project forward. Request initial
Commission authorization of $1,510,000 for the EGSE project that is ultimately expected to cost
approximately $44,410,000. 
SYNOPSIS: 
This authorization covers necessary design work to enable the staff to move forward in preparing
initial scoping documents, cost estimates, schedule phasing plans; all of which is necessary for 
the detailed engagement and coordination with over two dozen passenger airlines at the Airport.
The ultimate project is envisioned to enable the replacement of approximately 330 baggage tugs,
190 belt loaders, 70 pushback tractors and other various pieces of fossil-fuel based GSE with 
EGSE. The environmental goal will utilize energy efficient electric equipment, reduce use of
fossil fuel, reduce air emissions by 10,900 metric tons of Carbon Dioxide (CO2) annually, and
improve air quality for the Puget Sound Region. 10,900 tons of CO2 equates to approximately
1,500 vehicles off our public roadways. 
Good coordination has already occurred with the airlines headquartered here near the Airport.
Both Alaska and Horizon Airlines have indicated a strong interest in converting from fossil fuel
GSE to EGSE. Airport staff has received proposed locations from Alaska Airlines for charging

equipment at their gate areas. This authorization will enable staff to identify the best locations
for the charging stations and the ability of our Airport's existing electrical systems to support the
equipment that would serve the electric baggage tugs, belt loaders, and pushback tractors. 
This project is made up of three parts: 1) the airport electrical infrastructure within the terminal
building; 2) the charging stations just outside the terminal building within the aircraft parking
locations; and 3) the tug, loader, and tractor vehicles that are driven below the terminal building
and throughout the aircraft parking positions. In general, this authorization would enable staff to
evaluate the extent of hazardous materials near electrical infrastructure that needs to be
upgraded; purchase and install electrical meters to determine the extent of upgrades necessary; 
determine the necessary size of charging station equipment; optimize layouts of equipment near
aircraft; prepare solicitations for firm pricing of chargers and electrical vehicles; perform all
necessary preliminary design necessary to cost, schedule, and analyze the project; affirm the
business case; coordinate with the many airlines involved; and move the project forward from an
infrastructure standpoint. Staff will return to the Commission to request authorization prior to
awarding major charger and vehicle procurements.
Airport staff is working with agencies to secure and utilize grants that would help support the
project. Staff will seek to maximize use of a US Department of Energy (USDOE) Clean Cities
Coalition (CCC) $5 million grant toward purchase of electrical vehicles. In addition, staff is
coordinating with the Federal Aviation Administration (FAA) Voluntary Airport Low Emission
(VALE) Program for an approximately $7 million grant toward infrastructure improvements to
support the electrical chargers.
BACKGROUND: 
Most current GSE operated by airlines at the Airport are fueled by fossil fuels (Horizon Airlines
has some EGSE). They produce a significant percentage of the air emissions associated with
Airport operations. This equipment is vital to airline operations, performing a myriad of complex
and time-sensitive functions essential to the unimpeded flow of airfield operations. These
functions include moving aircraft to and from the gate, as well as loading, unloading, and sorting
of aircraft baggage, food, supplies and cargo. 
Alaska and Horizon Airlines support the electrification of existing GSE and are working with the
Port to replace a majority of their fossil-fueled GSE equipment operated at the Airport. Alaska
and Horizon fleets comprise approximately 35% of the total fleet at the Airport (currently there
are approximately 600 - 800 pieces of fossil-fuel based equipment owned by all airlines and
support providers at the Airport). We anticipate that a majority of Sea-Tac airline carriers will
ultimately participate in this project through an airline consortium where the carriers lease the
EGSE vehicles from the Port and manage maintenance. A consortium lease would not be
entered into without prior Commission Authorization that is anticipated to occur next year. An
airline consortium has been leasing the fuel system and managing fuel distribution for years.

Electricity is a viable alternative for powering most types of GSE. Electricity is unique among
alternative fuels in that there are no vehicle tailpipe emissions. Although there is some increase
in offsite power generating station emissions (if generation is fossil-fueled) resulting from
increased demand required to recharge EGSE vehicles, conversion to EGSE is considered a very
effective emission reduction strategy. This is especially true with the high percentage of
hydroelectric power generation used in the Northwest. 
As a technology, EGSE is rapidly gaining acceptance at airports around the nation. Some of the
issues surrounding electric on-road vehicles (i.e. performance and range) are not issues in the
confined airport setting. When not in use, electric motors shut down, which eliminates
unnecessary idling that occurs with gasoline or diesel engines. Therefore, the use of electricity as
a transportation fuel to power battery-powered electric vehicles is the most beneficial and
effective emission reduction strategy for this operation. 
Port staff is currently determining the best way to partner with airline carriers to support the
move to cleaner GSE on the ramp. Since this equipment would require new infrastructure to
charge the EGSE, Port staff must explore options for equipping gates to accommodate new
equipment. This authorization will enable necessary preliminary design to accommodate the
infrastructure needs, charging stations, and vehicles. 
PROJECT DESCRIPTION/SCOPE OF WORK:
Project Statement: 
This project will provide permanent electric power, chargers, and approximately 650 EGSE 
vehicles throughout the Airport to serve the passenger airlines. 
Project Objectives: 
Reduce annual emission of CO2 by approximately 10,900 tons per year by converting to
EGSE vehicles 
Maximize use of existing infrastructure to reduce environmental impact 
Minimize aircraft parking ramp-area operational impacts to airlines 
Provide continuous electrical power to various charging station locations that will be in
proximity to many of the 80 existing aircraft parking gates and other areas where EGSE
vehicles will park and be charged. 
Standardize design throughout the Airport to minimize installation, operation and
maintenance costs. 
Reduce the net operating and maintenance cost for the airlines and Airport combined

CPE Impact                        This project will increase CPE by
approximately $0.17 by 2013.
However, there will be no increase
to the 2011  2015 business plan
forecast as these projects are
included. 
OPERATION & MAINTENANCE IMPLICATIONS: 
It is anticipated that the majority of O&M costs, such as maintenance of vehicles (tires, batteries,
brakes) will be accomplished by an airline consortium or airline subcontractors while electrical
infrastructure within the terminal building, or just outside, will be maintained by Airport staff.
More detailed O&M costs will be available when project is design is completed. 
ECONOMIC IMPACTS: 
While the project supports local construction employment, the project does not create any
incremental economic impacts apart from supporting the existing operational economic benefits 
of the Airport. 
ENVIRONMENTAL/COMMUNITY BENEFITS: 
The project will utilize energy efficient electric equipment, reduce use of fossil fuel, reduce air
emissions by 10,900 metric tons of CO2, and improve quality of air for the local communities
and Puget Sound Region. This project supports Airport environmental goals to improve air
quality, reduce greenhouse gas emissions and deploy technology when it can reduce energy
demand.

ALTERNATIVES CONSIDERED/RECOMMENDED ACTION: 
Alternative 1: Install electrical infrastructure throughout all Concourses and Satellites to provide
power to electrify fossil fuel GSE and reduce air emissions at the airport. Maximize the use of
grants to benefit both the Port and Airlines. This is the recommended alternative. 
Alternative 2: Do Nothing. Should this project not go forward, the allocated Federal Grants to
the Port, will be relinquished. The Port will not realize a reduction in fossil-fuel emissions. This
is not the recommended alternative.
