ISWMP Purpose
Analyze, document, and recommend improvements for how solid waste is managed in areas such as:
• Solid waste collection
• Convenience centers
• Transfer stations
• Energy recovery
• Landfilling
• Recycling and bioconversion

WGS Landfill April 2021
7
Implementation Plan – 6. Household Hazardous Waste and E-Waste

o Community event expansion
o Cart inspection and compliance enforcement increases
o Promotional partnerships with major retailers
9
Implementation Plan – 8. Facility Capacity and Siting
• Metal recycling bins now at every convenience center and transfer station
• Potential reuse stations at disposal sites - Future
• Keehi Transfer Station: Open-top loading, bulky waste acceptance, review other materials, assess expanded hours and accepting green waste
o Construction in progress (11/21 completion), combustible bulky accepted
• Kapaa Transfer Station: Green waste loadout, repairs, structural improvements
o Construction in progress (9/21 completion), repairs/improvements to be bid out by end of FY21
• Kawailoa Transfer Station: Second load-out area
o Construction to be bid out by end of FY21
10
Implementation Plan – 8. Facility Capacity and Siting (continued)
• H-POWER baling equipment on-island and successfully tested; permitting in process
• New landfill site selection project initiated
• Campbell Industrial Park facility assessment and development:
o White goods processing now operating in Solar Building
o New Convenience Center and Baseyardconstruction solicitations out now
o Materials recovery facility in pre-planning
11
Implementation Plan – 9. Materials Marketing and Procurement
• HI-5 redemption center location identification –Ongoing
• Tire processing at H-POWER – Increased tire acceptance limits
12
Major ISWM Change Outside of ENV –C&D Landfill
• PVT accepts nearly 300,000 tons of C&D waste per year for recycling or disposal
• PVT Changes
o Unable to expand due to Act 73
o Discontinued reuse and recycling system
o No reclamation of interred wood waste
o Asbestos no longer accepted (City now takes at WGSL)
o Will no longer accept C&D disaster debris
• No other planned C&D Landfill per State DOH
• City preparing to take materials on closure (~5 years):
o C&D waste
o Petroleum contaminated soil

WGSL Chronology• 1987: WGSL began operations (no closure date in order)
• 1989: State Land Use Commission (LUC) approved 26 acre expansion
• 2003: LUC approved 21 acre expansion (stated closure date of 2008 on LUC order)
• 2004: LUC granted deadline extension to select landfill site to Dec 1, 2004
• 2004: Reso No. 04-348: Council selected WGSL as City’s future landfill site,
concluding that:
o WGSL site has at least 15 years of capacity left
o The WGSL site is the most economical site for which all costs and revenues are known factors
o Procuring and developing another site would be extremely costly
o An operating contract is already in existence
o The landfill operator is committed to addressing community concerns
19
WGSL Chronology• 2008: LUC extended deadline to accept waste to November 1, 2009
• 2008: ENV filed application for new Special Use Permit (SUP) (SP 09-403) which would authorize ENV to use an additional 92.5 acres at WGSL and operate WGSL to capacity
• November 1, 2019: SUP approved by LUC with conditions:
o “By no later than December 31, 2022, the Applicant shall identify an alternative landfill site that may be used upon closure of WGSL.”
o “WGSL shall close by no later than March 2, 2028. The WGSL shall not accept any form of waste after March 2, 2028.”
20
Waste Diversion Efforts
• Landfill MSW Down 85% since 2007:
o Economic recession 2008
o Since 2012 diverted: Sludge Bulky items Expired food waste Treated medical waste
• Landfill Still Needed for:
o H-POWER ash and residue (200,000 tpy)o Auto Shredder Residue (ASR) (35,000
tpy)o Asbestos Containing Materials (ACM)
(5,000 tpy)o WWTP grit/bar screenings (1,000 tpy)o Dead animalso HECO/refinery sludgeso Public with rock, dirt, concrete (300/mo)o Disaster C&D Debris
o Future: C&D waste diverted from PVT Landfill
*Post closure care: 30 years, possibly longer
21
Progress Towards Future Landfill Site
• District Boundary Amendment (DBA): ENV following HRS CH. 343 to determine format of environmental review before submitting DBA application for WGSL
• Act 73: o Prohibits construction, modification, or expansion of waste disposal facilities
without first establishing a buffer zone of no less than one-half mile between the edge of the waste or waste activity and the property line of the nearest residence, school, or hospital
o Provides that no waste or permitted disposal facilities shall be located in a conservation district
• ENV re-evaluating sites including but not limited to the sites identified in the 2012 and 2017 reports
• Although not required, the active area of WGSL already complies with Act 73
22
Progress Towards Future Landfill Site
• ENV is working with consultants to narrow down list of potential landfill sites
• Considerations include, among others:
o Capacity
o Distance from residences, schools, and hospitals per Act 73
o Avoidance of conservation districts per Act 73
o Avoidance of important agricultural lands
o UIC/No Pass zone constraints
o Distance from Potable water wells
o Outside tsunami inundation zones
o Sea level rise
o Proximity to H-POWER
o Land acquisition and development costs

Airspace Analysis & Other Considerations
• LUC order to close WGSL by March 2028
o Currently, WGSL has 5M cu yd or 15 years of capacity. In 2028, at current
disposal rates, could have 2.5M cu yd remaining (C&D waste may be factor)
o Initial cost of closure estimated at $55M
o Post closure care costs for 30 years estimated at $15M
• Future landfill challenges
o Environmental justice concerns
o Industry standard: Minimum of 10 years to site, permit, and develop a new
landfill
o EIS could take up to 4 years
o Potential site options limited by Act 73
o Cost (next slide)

Cost Analysis Example
Phase Example Site
1. EIS $5,000,000
2. Acquisition $10,000,000
3. Road Improvement $10,000,000
4. Access Road $5,000,000
5. Landfill Construction $180,000,000
TOTAL $210,000,000
