ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to execute procurement
contracts for the purchase of three pieces of runway snow removal equipment at Seattle-Tacoma
International Airport for a total authorization of $2,200,000. 
SYNOPSIS 
This memorandum requests authorization for the Airport to acquire three pieces of runway snow
removal equipment: one deicer truck and two snow blowers. The Airport needs to replace two
(2) 38 year-old snow blower units with new higher capacity equipment that can keep up with the
removal fleet during heavy snowfalls. It is also necessary to replace an older 1986 model 2000
gallon chemical deicer truck with a higher capacity 4000 gallon unit in order to meet the antiicing
and de-icing requirements of two (2) dedicated runway removal teams. The purchase of the
additional equipment will increase runway availability and reduce departure and arrival delays
during snow and ice control activities. 
This project was included in the 2013  2017 capital budget and plan of finance. 
BACKGROUND 
Based on the requested improvement in runway snow removal clearance times in order to
minimize departure delays to the greatest extent possible during snow events, multiple snow
removal scenarios were reviewed. It was agreed that the Airport's current snow removal program
of two (2) dedicated runway removal teams, first implemented in 2012 will continue. It was also
decided that introducing new equipment gradually into the fleet was the best approach to

Template revised May 30, 2013.

accomplish continued clearance operations on all runways during the snow and ice control
season. 
PROJECT JUSTIFICATION AND DETAILS 
The purchase of the identified three (3) pieces of snow removal equipment will improve the
timeliness and effectiveness of snow and ice control activities on the Airport's runways and
taxiways. 
New Deicer Truck: 
In order to keep up with the removal fleet and achieve the desired anti-icing and deicing
applications, we need to replace an older 2000 gallon truck that has a 50' application boom with
a 4000 gallon unit that has a 75'-80' application boom. With this purchase we will have three (3)
4000 gallon or large deicer units all equipped with 75' or greater application booms.In a onepass
removal or anti-icing operation before the snow accumulates, two units are used (one on
each side of the runway) to achieve full width and length chemical applications very quickly. We
intend to keep the 1986, 2000 gallon unit as back-up equipment. 
Snow Blowers: 
During a snow event, snow build-up along the edge of the runways could exceed the twelve inch
height limit during continues snow removal operations. When this occurs, snow is collected and
blown up and over the berms and past the runway edge lights. High capacity snow blowers will
maximize runway availability by clearing the edge berms faster and more effectively than the
capabilities of our current snow blowers. 
We will be replacing two (2) older snow blowers, which are approximately 38 years old
(vehicles 318 and 319) and have reached the end of their dependable life spans. The intent is to
surplus both of these units when their replacements are delivered and accepted. 
Project Objectives 
The primary objective is to increase runway availability and reduce departure and arrival delays
during snow and ice control events. The purchase of the three identified pieces of removal
equipment will improve the Airport's ability achieve this objective. 
Scope of Work 
Purchase one (1) runway snow deicer truck in 2014, one (1) runway snow blower truck in 2015, 
and one (1) runway snow blower truck in 2016 for improved snow and ice control efforts at
Seattle-Tacoma International Airport for a total authorization of $2,200,000.

CPE Impact             CPE will increase by $.01 when all equipment is acquired
in 2016. No change compared to business plan forecast as
this project was included. 
Lifecycle Cost and Savings 
The net increase over the current Operation and Maintenance Costs is estimated to be $6,500
annually with the addition of the deicer truck and systems. The first year of operation, the O&M
costs will be minimal while under warranty. 
STRATEGIES AND OBJECTIVES 
This project supports the Port's Century Agenda objective of meeting the region's air
transportation needs at Seattle-Tacoma Airport for the next 25 years. It also supports the
Airports' strategy of operating aworld-class international airport by ensuring safe and secure
operations. 
TRIPLE BOTTOM LINE 
Economic Development 
This project provides an economic benefit by improving the timelines and cost effectiveness of
snow and ice control activities and minimizing aircraft arrival and departure delays for our
airline business partners and the travelling public. 
Environmental Responsibility 
Equipment purchased will meet EPA fuel efficiency standards. 
The additional equipment helps the environment by enabling snow to be removed more quickly
from the runway by mechanical removal methods and could reduce chemical applications on the
runway. Improved snow removal efficiency will help reduce aircraft fuel burn by reducing
departure delays. 
Community Benefits 
The community benefits are associated with providing a safe operating environment and
minimizing arrival and departure delays for the traveling public thus minimizing impacts to our
Airport business partners.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)   Continue using the current equipment that is aging  and growing more
inadequate for current two team runway snow removal operations. This is not the recommended
alternative. 
Alternative 2)  Procure all three (3) pieces of snow removal equipment in 2014. If approved,
this would result in spending all 2.2 million in 2014, which would result in higher level of capital
spending in 2014 than originally planned. This is not the recommended alternative. 
Alternative 3)  Purchase the three (3) identified pieces of additional runway snow removal
equipment in a phased approach by procuring the new deicer unit in 2014 and the two snow
blowers in 2015 and 2016. This approach phases the $2.2 million of capital spending over the
identified 3 year period. This is the recommended alternative.
