The Environmental Notice, June 8, 2026 (PDF)

The County of Kaua`i, Department of Public Works, Solid Waste Division (County) is proposing to develop Cell 3 to gain additional airspace capacity at the Kekaha Landfill located in Kekaha, Kaua`i, Hawai`i. Kekaha Landfill is the only active, permitted municipal solid waste landfill on Kaua`i. It was established in 1953 and has been in continuous operation through sequential operational phases and expansion cells. Kekaha Landfill’s currently permitted landfill area is 74 acres, which includes the Phase I, Phase II, Cell 1, and Cell 2 areas. Kekaha Landfill is anticipated to have capacity through 2030. The County is proposing the Cell 3 vertical expansion to meet the near-term waste disposal requirements for Kauaʻi while a new landfill site can be permitted and constructed (which is anticipated to take approximately 10 years). Cell 3 would provide additional airspace through a vertical expansion over the footprint of the Phase I and Phase II landfill areas. An overliner system would be constructed above the pre-subtitle D, unlined Phase I disposal area to collect and recover leachate from future waste placed in Cell 3. The maximum elevation of Cell 3 would be 85 feet (ft) above mean sea level (amsl) in Phase I and 188 ft amsl in Phase II. Cell 3 would cover approximately 40 acres within the existing 74-acre permitted, limit-of-waste footprint. Cell 3 would add an additional, estimated 10 years of capacity to Kekaha Landfill.
