SUBJECT:  Gate Aircraft Utilities Improvements Project (CIP # C800019) 
Amount of This Request: $328,000 (Expense) Source of Funds: Airport Development Fund 
State and Local Taxes Paid: $736,000      Jobs Created: 21 
Total Estimated Cost of Project: $13,211,000 (including expense) 
ACTION REQUESTED: 
Request Commission approval of $328,000 expense funds for regulated materials management
(RMM) and training for the Seattle-Tacoma International Airport (Airport) Gate Aircraft Utilities
Improvements Project (#C800019), which were not included in the original authorization request.
This request completes the necessary Commission authorization for the expense funds needed for
this project. 
SYNOPSIS: 
On June 14, 2011, the Commission authorized an increase of $3,498,000 to the project's capital
budget for a new total project capital budget of $12,883,000. Although the Commission memo
indicated a total budget of $13,211,000, including expense funds for Regulated Materials
Management (RMM), the formal request for authorization of the expense funds was not
included.
Currently there are 31 Airport-owned gates on Concourses B and C, and the North and South 
Satellites that do not have full aircraft utility capabilities. There are varying amenities at these 
gates, including 400 Hz ground power supply and potable water. Airlines pay the same lease
rate regardless of the amenities provided. This project would bring the 31 "utility deficient"
Port-owned gates up to the same standard, including 400 Hz power and potable water. This
project has been coordinated with the air carriers involved in the realignment program and
includes future aircraft requirements. This project would replace three outdated airline-owned
