DUNCAN CSWLF Landfill - Duncan, Arizona Solid Waste Management Facility

DUNCAN CSWLF is an operational landfill located in Duncan, Greenlee County, Arizona, United States. It is classified under NAICS code 562212 (Solid Waste Landfill) and serves the municipal solid waste disposal needs of the surrounding area. As a landfill in the United States, this facility operates under the regulatory oversight of the US EPA, specifically RCRA Subtitle D for municipal solid waste landfills, and Clean Air Act regulations for landfill gas emissions. The facility's location in rural Arizona suggests it may handle waste from a smaller population base, typical of landfills in less densely populated regions. The environmental significance of DUNCAN CSWLF lies in its role as a waste disposal endpoint for the community. Proper landfill management is critical for minimizing methane emissions, controlling leachate to protect groundwater, and managing traffic and community impacts. The facility's operational status indicates ongoing waste acceptance and management.

The landfill is situated in a semi-arid region of Arizona, where groundwater resources are particularly sensitive to contamination from leachate. Effective leachate management and gas collection systems are essential to mitigate risks to local aquifers and reduce methane emissions. The facility's proximity to the community of Duncan also necessitates careful traffic management and odor control to minimize neighborhood impacts.
