SYNOPSIS 
This memorandum requests authorization for construction and the approval to advertise for
construction bids for the Trash Handling & Recycling System project. This project provides one
trash and one recycle compactor at each site for a total of five sites at designated locations on the
airfield ramp area. A sixth installation site is being determined and authorization for that will be
requested later, if necessary. The Commission previously authorized $752,000 to complete 
design and pre-purchase compactors on April 22, 2008. This authorization for construction will
increase the project authorization by $724,000 for a total project authorization of $1,476,000.
The airlines support this project. 
BACKGROUND 
Several air carriers at the Airport have started recycling of off-aircraft waste, aimed at reducing
landfill waste.  They see this as one way of demonstrating their environmental commitment. 
Recent studies of off-aircraft waste indicate as much as forty percent of the waste stream can be
recycled.  Industry-wide, airlines and airports are working to divert these recyclables from
landfill disposal in an effort to reduce negative impacts on the environment and reduce waste

disposal costs. Examination of the Airport's ramp facilities and operations has identified
opportunities to support airline recycling efforts as well as to reduce threats to airfield operations
from Foreign Object Damage (FOD) and bird-strike hazards that result from open top dumpsters.
The project will also reduce vehicular congestion resulting from numerous trash and recycle haul
trucks. Each airline currently manages its own waste stream, using various containers, which are
maintained and serviced through separate contracts. Unlike the passenger terminal, the airfield
ramp areas are not utilizing a centralized waste management and recycling system. This project
will extend the Airport's award-winning trash and recycling program to the airfield ramp areas,
and support the Port's commitment to becoming the cleanest, greenest port in the United States. 
At this time, five locations are designed and ready for installation. The overall project intends to
have six locations; however the site for the sixth pair of compactors has not been determined due
to airline relocations and other factors. The recommended action is to proceed immediately with
the portion of the project that is ready, so the Port and airlines can realize the environmental and
economic benefit as soon as possible. The last site will be brought forward for Commission
authorization when the location is settled and the design is completed. 
PROJECT DESCRIPTION/SCOPE OF WORK 
Project Statement: 
The purpose of this project is to centralize trash handling and recycling on the airfield, encourage
and extend recycling opportunities to airlines, and reduce the negative effects of the existing
trash handling methods. The Airport will install, operate, and maintain large-capacity trash and
recycling compactors at five convenient locations throughout the airfield ramp areas. Compactor
sites selected to achieve optimal use by the airlines and their ramp service personnel are at
Concourses A, B, D, North Satellite, and South Satellite, with one site yet to be determined. 
Each site will be equipped with the following: 
A pair of self-contained 30 yard compactors, including one trash compactor and one
recycling compactor. 
Electrical service to power compactor hydraulic system and local control system for each
compactor. 
Automatic monitoring systems that will sense the pressure within each compactor and alert
the hauler when the compactor is near capacity, optimizing hauling frequency and thereby
minimizing truck traffic in the aircraft areas. 
Electronic key systems, which will record usage by each tenant, airline, or concessionaire. 
The operation and maintenance costs of these compactors will be recovered by charging usebased
fees. Each user will be charged a per-toss fee for use of the trash compactor, while a toss
in the recycling compactor will be free. This system of charging costs to users was established
within the terminal to create an incentive to recycle while recovering costs, and has been a

cornerstone of our successful recycling program. Airlines that are currently paying for
independent recycling services will be able to eliminate those costs, and recognize a net overall
savings. 
Project Objectives: 
Improve the recycling program at the Airport. 
Reduce the airlines' trash handling costs. 
Reduce vehicle traffic on the airfield. 
Ensure no impacts to flight operations on the airfield ramp area during the development and
construction of each site. 
Scope of Work: 
Develop infrastructure to accommodate the installation and operation for five compactor sites
on the airfield ramp area. See the attached site plan. Infrastructure development will, at a
minimum, include: 
1)  Site preparation for installation of bollards, steel plates and anchoring system. 
2)  Installation of electrical power and control systems. 
3)  Installation of communication system. 
4)  Re-stripping driveways and parking areas. 
5)  Installation of signage. 
6)  Commissioning of each set of compactors. 
7)  Training to Airport and airline staff. 
8)  Closeout of completed project. 
STRATEGIC OBJECTIVES 
The Trash Handling and Recycling Program supports several of the Port's Strategies and
Objectives, notably: 
Ensure Airport and Seaport Vitality 
This project will provide a lower cost and a more efficient trash and recycling system for Airport
tenants. In contrast to current manually operated open-top dumpsters, the closed compactors
with automatic doors will prevent birds from extracting FOD items and scattering them across
the ramp, reducing the risk of ingestion into aircraft engines. Available ramp space will be
increased, by replacing numerous small capacity waste collection units with fewer, strategically
located large capacity units.

Exhibit Environmental Stewardship through Our Actions 
This project is in alignment with the Port's goal of becoming the cleanest, greenest and most
energy-efficient port in the United States. By increasing the amount of recyclable material
diverted from the waste stream, the Port will be helping to reduce the amount of material
delivered to regional landfills. Air emissions and fuel consumption will also be reduced as a
result of decreased ramp and public arterial traffic. This project supports and encourages airline
environmental initiatives.

ECONOMIC IMPACTS 
From a financial analysis perspective, the positive net present value for this project is based on
viewing the Airport and airlines together. The Port will incur increased Operation and
Maintenance (O & M) costs of about $350,000 per year. These O & M costs are the expenses
related to trash disposal and represent a savings of nearly $250,000 per year over what the
airlines are currently paying. From a financial statement perspective, the Airport will charge the
airlines usage fees sufficient to recover the operating and capital costs, resulting in an increased
net operating income. 
ENVIRONMENTAL SUSTAINABILITY/COMMUNITY BENEFITS 
There are significant recycling benefits to installing a centralized waste handling and recycling
system on the airfield. Airlines participating in an incentive based recycling program will reduce
the amount of waste sent to regional landfills, while helping to reduce traffic via more efficient
compactor hauls. Reductions in traffic will also result in lower fuel consumption, air emissions
and vehicular congestion in neighboring communities. 
TRIPLE BOTTOM LINE SUMMARY 
This project is expected to help reduce the overall operating costs of the airlines and promote
recycling efforts. Reduced ramp vehicular traffic servicing existing waste collection units will 
result in increased ramp safety, decreased air emissions, and decreased fuel consumption. This
will also help reduce vehicular traffic on neighboring public streets and highways.
