(Former) Hawaiian Western Steel Wastepile Landfill in Kapolei, Hawaii - Solid Waste Management

The (Former) Hawaiian Western Steel Wastepile is an operational landfill located at 91-150 Hanua Street in Kapolei, Hawaii, United States. This facility serves the Honolulu County area and is classified under NAICS code 562212 for Solid Waste Landfills. As a landfill, it plays a key role in the region's solid waste management infrastructure. Operating within the United States, this landfill is subject to federal regulations under the Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs municipal solid waste landfills, as well as Clean Air Act standards for landfill gas emissions. Hawaii's unique island geography and high rainfall present specific challenges for leachate management and groundwater protection. The landfill's location in Kapolei, a growing urban center on Oahu, underscores its importance in managing waste from residential and commercial sources. Proper landfill gas collection and leachate control are critical to minimizing environmental impacts in this sensitive island ecosystem. The facility contributes to the state's waste management strategy, supporting public health and environmental protection.

As a landfill in Hawaii, the facility must manage leachate effectively due to high annual rainfall, which increases the risk of groundwater contamination. Landfill gas, primarily methane, requires collection and control to reduce greenhouse gas emissions and comply with Clean Air Act regulations. Proximity to urban areas in Kapolei necessitates careful traffic management and odor control to minimize community impacts.
