ACTION REQUESTED 
Request authorization for the Chief Executive Officer to execute a contract to purchase an
Aircraft Rescue Fire Fighting Vehicle with a high reach extendable turret for the Port of Seattle
Fire Department at Seattle-Tacoma International Airport for an estimated cost of $1,450,000. 
SYNOPSIS 
The Federal Aviation Administration (FAA) requires that Sea-Tac Airport has three in-service
Aircraft Rescue Fire Fighting (ARFF) vehicles at all times to support safe aircraft operations.
This is accomplished by maintaining four ARFF vehicles, three in active service and one in
reserve status.  The oldest of the four vehicles is nineteen (19) years old and is in need of
replacement. Adding a high reach extendable turret (HRET) will enhance the Fire Department's
capabilities.  Currently,  the  Port  of  Seattle  Fire  Department  (POSFD)  ARFF  Vehicles  are
equipped with manual turrets. The HRET is new automated technology that is 53% more
effective for fuel pooling fires and provides a significant advantage of accessing into the fuselage
to mitigate interior fires.
BACKGROUND 
The FAA Part 139, which regulates the requirements for ARFF vehicles, categorizes airports by
index based on aircraft size and movements.  An airport with five or more average daily
departures of aircraft at least 200 feet in length (large wide-body aircraft such as a 777 or larger)
is classified as Index E.  The FAA requires Index E Airports such as Sea-Tac to have three
ARFF vehicles in-service at all times. If less than three vehicles are in -service the Airport is at
risk of being unable to accept large wide-body aircraft, and could possibly face closure by the
FAA or be restricted to receiving only smaller category aircraft.

The Fire Department maintains the FAA requirement with three ARFF vehicles in-service and
the fourth vehicle in reserve status. The replacement plan designates the oldest vehicle to be
replaced every 5-8 years. The serviceable life is 10-12 years and the vehicles in the current fleet
are 1996, 2000, 2006, and 2008 year models. This authorization request would replace an aging
ARFF Vehicle currently in reserve status, and eligible for surplus or donation. This purchase will
replace Truck 763/Unit #958, a 1996 Oshkosh T-3000 that will become surplus, allowing Truck
765/Unit #1241, a 2000 Oshkosh T-3000 to be placed in a reserve status to extend its service life
for several more years. The latter truck is scheduled to be replaced in 2017; the 2006 truck is
scheduled to be replaced in 2022; and the 2008 truck is scheduled to be replaced in 2024. 
The Port Fire Department's Vehicle Replacement Plan for ARFF vehicles is designed to provide
for the maximum amount of service life while maintaining the highest level of reliability for all
vehicles  in  use  by  the  Fire  Department.  Through  strategically  planning  and  scheduling
replacements, we can extend each vehicle's useful service life by moving older vehicles into a
reserve status. When the new ARFF vehicle is received, the oldest and least reliable vehicle will
be either sold or donated.
PROJECT JUSTIFICATION AND DETAILS 
As noted above, the FAA requires the Airport to have three (3) in-service ARFF vehicles at all
times. Having fewer than three vehicles in service presents the risk of the Airport's being unable
to accept large wide-body aircraft. Potentially, the Airport could face closure by the FAA or be
made subject to receiving only smaller category aircraft. 
Currently there is an increased risk of breakdowns associated with aging vehicles. This risk is
evidenced by maintenance issues with the current reserve vehicle: 
ARFF#763 was out of service nine months in 2014, which led to our borrowing a
replacement ARFF vehicle from North Bend Training Academy. 
ARFF #763 is currently out of service for an anticipated additional four months awaiting
fabrication of parts. Again, we are borrowing a replacement ARFF vehicle from North
Bend Training Academy. 
Additionally there are long delays acquiring parts for the older equipment, which require the Fire
Department to borrow a vehicle to maintain our index and accept larger aircraft without
disruption. Purchasing a new vehicle at this time will allow the Airport to have a reliable set of
ARFF vehicles. This purchase will replace ARFF #763. 
A competitive procurement is intended for this vehicle. The specifications include: 4500 gallon
water capacity; 600 gallon of AFFF (Foam Capacity); Suitable complementary agent (Dry
Chemical/Halotron); and 65-foot High Reach Extendable Turret (HRET). 
The HRET is an enhancement that will allow additional capability not only during an incident 
with a passenger aircraft, but will also assist with a water supply to upper decks of large aircrafts,
the roof tops of our concourses, and also provide penetrating capability for cargo aircraft. The

FAA recommends that airports at C Index and above have at least one HRET to support ARFF
operations (Advisory Circular No: 150/5210-23).

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
1) Extend the life of existing fleet 
During 2015 prioritization of capital purchases it was agreed to delay this purchase out to early
2016 to help mitigate cost growth of the International Arrivals Facility. We could choose to
continue to delay this purchase. However,  a continued delay would increase the risk of
breakdowns associated with aging vehicles as noted in the justification section of this memo. 
Pros: Continue to delay capital spending. 
Cons: Increasing risk of not being able to meet FAA requirements due to vehicle down
time. Additional risks include not being able to effectively supply water to upper levels of
larger aircraft, inability to effectively penetrate Cargo holds to mitigate fire and continued
inability to more effectively supply water to concourse rooftops. 
This is not the recommended alternative. 
2) Purchase a 3,000 gallon vehicle with a 50' HRET 
This option provides opportunity to improve our current abilities. The HRET is an enhancement
that will allow additional capability not only during an incident with a passenger aircraft, but will
also assist with a water supply to upper decks of large aircrafts, the roof tops of our concourses,
and also provide penetrating capability for cargo aircraft. The FAA recommends that Airports at
C Index and above have at least one HRET to support ARFF operations (Advisory Circular No:
150/5210-23).
Pros: Provides enhanced capabilities to meet current FAA expectation of having one
vehicle on site with a HRET (Advisory Circular No: 150/5210-23). This improves ability
due to elevated water supply and cargo penetration capabilities. 
Cons: Does not allow us to solve current and upcoming challenges as the HRET is
limited by a 50' reach. With the proposed construction of a 75' bridge in conjunction
with the IAF project the 50' HRET would not as effectively protect the exposure as a 65'
HRET as well as sections of the Sound Transit light rail. 
This is not the recommended alternative. 
3) Purchase a 4,500 gallon vehicle with a 65' HRET 
This option best fits our future strategic goals and operational needs. During the recent Asiana
777 incident in San Francisco it became apparent that water supply is essential for efficient
operations. This vehicle will allow us to integrate new technology, increased water/foam
capacities, and capabilities to better support a longer operational period. This particular model
not only enhances our water supply but also accommodates a 65 foot HRET. This length HRET
provides additional capacity to support the following ARFF and Structural areas; penetration into
larger aircraft and cargo holds, support an essential water supply to provide greater protection to
the roof tops of our concourses, support the future bridge associated with the new International

Arrivals Facility and assist with mutual aid for Sound Transit at the light rail station, trains and
elevated guideways. 
Pros: Provides enhanced capabilities to meet current FAA expectation (Advisory
Circular No: 150/5210-23) of having one vehicle on site with an HRET. This improves
ability  due  to  elevated  water  supply  and  cargo  penetration  capabilities.  Provides
additional agent quantities to better mitigate larger incidents and be the designated safety
vehicle on scene. 
Cons:  Size may limit access in and around terminal area; however, it will fit in the
station garage. This is the reason this would be the only one of this size in the fleet.
This is the recommended alternative.
