Subject: Transfer Station Enhancement Plan
Dear Chairman Arakaki and Council Members,
The enclosed Transfer Statiori Enhancement Plan, dated May 2004, was finalized as part of the
ongoing implementation of the County of Hawaii Integrated Solid Waste Management Plan.
Initial work and research was done as part of a grant from and the U.S. Environmental Protection
Agency. The plan was refined and finalized to best meet the County's needs.
As a point of reference, this plan maybe also found on the County of Hawaii, Department of
Environmental Management Webpage.
Aloha,

County of Hawaii
Transfer Station Enhancement Plan
1. Introduction
1.1 Purpose
The purpose of this plan is to provide a brief description of one of the County of Hawaii's
various initiatives to improve solid waste services for residents. Transfer Station
enhancement is currently in the early stages of planning. This document is intended to
serve as a discussion point for further planning, permitting and design of the facilities.
Operation of the facilities is not covered in this Plan and is addressed in a separate
Operations Narrative to be developed by DEM.
1.2 Objectives of Transfer Station Enhancement
The Integrated Solid Waste Management Plan (ISWMP), accepted in 2002, commits the
County to increase recycling and diversion of waste from its current level of
approximately 15% toward the State mandated level of 50%. The transfer stations will
serve a critical role in the diversion of solid waste from its landfills by providing
enhanced recycling, and reuse opportunities. The 21 transfer stations are positioned
around the county to be convenient for residents to self-haul their waste, in lieu of
County-sponsored collection services. Recyclable materials from the rural transfer
stations will be consolidated and processed by recycling contractors at the East Hawaii
Regional Sort Station or other central facility.
The transfer station enhancements and the Sort Station are synergistic because the Sort
Station will provide a central processing area for recyclables to achieve economies of
scale. The public recycling drop-off area which is part of the Sort Station facility will
also be the largest collection of residential recyclables, based on existing transfer station
volumes and recycling participation.
After only a few months in operation, the Pilot project at Keeau Rural Transfer Station
demonstrated the ability to divert 20% of incoming waste by providing educational
materials, community outreach and convenient recycling opportunities.
1.3 Targeted Users
The transfer station network is reserved for use by residential self-haulers. In a recent
study the County determined that 87% of its single-family residential units self-haul
waste to one of the 21 transfer stations. The transfer station system will continue to be
reserved for residential users, while commercial recyclers will be encouraged to deliver
source separated loads to the Sort Station resource recovery yards established at or ncar
the Sort Station by contracted recycling vendors.
1
1.4 Establishing Priorities
The County will design approximately 3 different types of recycling centers at its transfer
stations, The selection of which type will be installed at which location will be based on
the level of service at each station in order to maximize the amount of material recovered
in relation to the capital and operating expense in providing these services. The level of
service standards will be modified to consider anticipated growth rate within the area,
commuting patterns, and available land area at the transfer stations as well as population
served and historical volume.
2. Locations
2.1 The Existing Transfer Station System
The County transfer station system is shown in Figure 1. All rural transfer stations are
maintained and operated by county personnel. Many currently have contractor-owned
drop boxes for recycling.
2.2 Priority Sites
A transfer station enhancement priority list was developed based on the level of service
and the distribution along commuting routes to maximize recycling opportunities for all
county residents. Enhancement priorities are shown in Table 1 along with the planned
services offered at each facility. Each service to be offered is described in Section 3 of
this document.
2.3 Schedule
The schedule for transfer station enhancements is dependent on the availability of
funding. Transfer Stations enhancements will be funded through a variety of sources
including County capital improvement funds, EPA grants specific to waste reduction and
recycling, Community Development Block Grants, and other federal grant programs.
Table 2 shows a proposed transfer station improvement schedule. This estimate is based
on favorable response from currently pending grant applications.

3. Services
3.1 Priority 1 Transfer Stations
Priority 1 sites are the lazgest and most heavily used on the island. These sites will be provided
the widest range of services in order to maximize their productivity. Priority 1 sites will have the
following services available.
Reuse Center: The purpose of a Reuse Center is to divert reusable items from the waste stream
before they become damaged or contaminated by commingled waste. The Reuse Center will
provide a managed alternative to scavenging, which was once common, but now prohibited.
Items with value such as new, undamaged, or repairable furniture, lumber, building materials,
tools, toys, kitchen utensils or lawn equipment will be taken to the Reuse Center, and accepted
by the manager rather than being disposed in the waste stream. Alternatively, persons with
interest in the material may browse reuse items while at the transfer station. The precise terms of
material re-distribution have not been determined pending a request for proposals from potential
private operators of the Reuse Centers. It is relatively certain that County personnel will not
become involved with sale or collection of money from this source.
Deposit Beverage Redemption Center: Beginning In June 2005, certain beverage containers
defined in Hawaii Revised Statutes Section 342-G part 101 will be charged a refundable deposit
upon purchase. The County will operate Redemption Centers at the five Priority 1 transfer
stations. The County-operated Redemption Center will accept qualifying containers and refund
the deposit to residents. Non-qualifying glass containers will also be accepted, but non-deposit
plastic, and metal container should be deposited in the traditional recycling bins. Bottles will
either be canceled (crashed) on-site or returned to a central processing facility for cancellation
through a contractual arrangement with a qualified recycling contractor.
Greenwaste Collection: An area of at least acre will be set aside for collection of greenwaste
from residential generators. Greenwaste will be delivered free of plastic bags and other refuse.
The greenwaste collection area will be provided with a compacted soil base. No food waste,
manure, animal waste or offal will be accepted in the greenwaste collection azea. It will be
deposited either in roll-off containers or on the ground. Periodically, the County or its
contractors will haul greenwaste intact or shredded to a central composting facility for
production of mulch or soil amendment. A small amount of shredded greenwaste may be
stockpiled at the site for collection by transfer station users.
Scran Metal Collection: A separate scrap metal collection area will be provided at priority 1 and
2 sites for the collection of appliances and other scrap ferrous metal. A concrete slab with curbs
will be provided for collection of metal. A roll-off container will be placed on the slab for
collection of small metal parts. The metals collection slab will be long and narrow so that
appliances are stacked in one or few rows that are accessible to a forklift. Only appliances and
5
metal parts from residential sources will be accepted. Vehicles will not be accepted. The
County or its contractors will periodically remove metals from the transfer stations and transport
to a central metals processing facility for recycling.
Recvclable Materials Collection Bins: Collection bins for 2-stream recycling will be placed
conveniently so that the number of stops will be minimized. The manner in which the 2-streams
of recyclable will be segregated will be decided based on proposals accepted from qualifying
recycling contractors in response to a Request for Proposal. Collection bins specified by the
County's recycling contractor will be placed at the transfer stations for collection of most types
of paper fibers, cardboazd specific types of plastic, glass, aluminum and tin. The county's
contractor will pickup full bins and leave empty bins on an as-needed basis. Recyclables will be
returned to a central processing facility for sorting and shipping.
Waste Collection: Non-sorted residential waste will be collected in 40-foot County waste trailers
for transport to a central processing or disposal facility. This is the primary existing activity at
the transfer stations, and this function will not substantially change. County personnel make
regular visits to the transfer stations to compact the load and estimate the time remaining to
capacity. Upon reaching capacity the east side transfer stations will be transported to the East
Hawaii Regional Sort Station where loads will be inspected, recyclables pulled out, repacked and
transported to Pu'uanahulu Landfill for disposal. The west-side transfer trailers will be
transported directly to the Pu'uanahulu Landfill for disposal.
3.2 Priority 2 Transfer Stations
Priority 2 Transfer Stations will provide the following Services (as described above):
• Greenwaste Collection
• Metal Collection
• Recyclable Materials Collection
• Waste Collection
3.3 Priority 3 Transfer Stations
Priority 3 Transfer Stations will provide the following Services (as described above):
• Recyclable Materials Collection
• Waste Collection

4. Design Concepts
4.1 Area Requirements
• Area requirements aze dependent on the services offered, property
geometry and topography. Since the transfer station system is made up
of various sized parcels, the type of collection mechanism for
g;eenwaste (containerized or paved/graveled pad) may need to be
adapted to fit the space requirements.
4.2 Access/Egress
All transfer stations are currently provided with all-weather access, egress and internal roads that
correspond to County standazds.
4.3 Surface Water Control
Site development standards are used for all transfer stations. Surface water run-on controls are
currently installed to prevent stormwater from entering waste collection areas. Priority 1 and 2
sites will be upgraded as necessary to collect stormwater from waste, greenwaste, and metal
collection areas for onsite disposal. The metals collection slab will be fitted with a sump and
drainage valve. Standing water will be examined for oil. If an oil sheen is present the water will
only be partially drained to prevent oil from escaping. Oil sheens will be absorbed using floating
oil collection pads. Stormwater will be disposed in an on-site dispersion pit.
4.4 Signage
Each transfer station will have a sign that identifies the facility, its owner, a point of contact in
case of emergency, and other information as required under HAR 11-58.1.
4.5 General Cost Estimates
The cost for developing transfer stations from their existing condition to the designated level of
service will vary widely between sites. Valid construction cost estimates cannot be completed
without further design services. Same fixed costs maybe identified at this stage as a baseline for
firrther investigation. The estimates below are based on standard general estimates for
construction in Hawaii, but do not include site work or preparation of the access roads. Also the
quantities shown are general estimates that are based on conceptual designs shown in Section 5.
These cost should not be used for budgetary purposes since major cost elements are currently
unknown.
