The process is underway to evaluate possible landfill sites to supplement or replace Oahu’s only municipal solid waste (MSW) landfill, the Waimanalo Gulch Sanitary Landfill (WGSL).

The issues surrounding landfills are among some of the most difficult public discussions around the country. Everyone agrees that efforts must be made to reduce the use of landfills through increased recycling, composting, waste-to-energy and other technologies. And everyone seems to understand that there needs to be a landfill to receive waste materials that cannot be processed otherwise. But when it comes to determining the best location for the landfill, that’s where the decisions get tough.

Currently, Oahu has two landfills: the City-owned Waimanalo Gulch Sanitary Landfill (WGSL) and the privately-owned PVT landfill. The WGSL is Oahu’s only municipal solid waste (MSW) landfill. The PVT landfill is designated for construction and demolition (C&D) waste only.

New Landfill
The location of a new landfill site to supplement or replace WGSL is being determined. The Mayor formed a Landfill Site Advisory Committee to assist the City in identifying siting criteria and ranking potential landfill sites. The committee met for the first time on January 20, 2011 and completed the process in April, 2012, identifying and ranking 11 potential locations. The meetings were open to the public, and public comment was accepted prior to the committee member discussions of agenda items. Meeting notices and summaries are linked in the side bar to the right.

The committee, with support from the City’s consultant, explored over 400 parcels on Oahu, including state, federal, county and private land. Technical and regulatory restrictions eliminated parcels from consideration, and the committee applied additional filters based on community concerns. The committee established a list of community-based, weighted criteria, which were applied to the remaining 11 sites, to provide a ranking.  The final report (and appendices) were submitted in September 2012.

The next steps are for the City administration to further evaluate the sites, submit recommendations to the City Council for review and approval, and develop Environmental Impact Statement(s) specific to the selected site(s). The public would be able to provide input during the City Council hearings and EIS.        

Continued Use of WGSL
Community concerns regarding the continued operation and expansion of the Waimanalo Gulch Sanitary Landfill have been addressed in a number of ways:

  • WGSL EIS and community input. An environmental impact statement (EIS) was prepared related to the expansion of the landfill. Oahu residents provided comments at community meetings held in July and August, 2006.
  • WGSL Oversight Advisory Committee. In addition, an oversight advisory committee was formed to provide a forum for community representatives to share concerns about the landfill and to ensure that it operates in a manner sensitive to the surrounding community.
  • Quarterly Public Hearings (see links to meeting notices and summaries in side bar). Further, the Land Use Commission required the City to hold public hearings every three months to advise on the status of the continued use of the Waimanalo Gulch Sanitary Landfill and the City's efforts to reduce landfilled waste.

The continued use of the WGSL is being determined. The City estimates the physical capacity of the landfill would enable it to continue to receive waste materials for at least the next 15 years. However, the State Land Use Commission (LUC), in response to community opposition to the landfill, limited its use by order. A 2009 LUC order required the City to begin the process of identifying one or more landfill sites to supplement or replace the WGSL by November 2010. The City’s own Integrated Solid Waste Management Plan calls for the City to identify a new MSW landfill by 2012. The LUC order acknowledged it will take the City at least seven years to construct and open a new landfill, but required WGSL to no longer accept MSW as of July 2012. Given these facts, the City is requesting an extension of the LUC deadline for acceptance of MSW at the landfill. It is essential for the City to maintain a landfill to accept MSW that cannot presently be reused, recycled or burned at H-POWER. Completion of a third boiler at H-POWER mid-2012, will substantially reduce the amount of waste disposal at WGSL.
