OLD NOGALES CSWLF is an operational landfill located in Tucson, Arizona, United States. It is situated east of I-19 on Hughes Access Road and serves the Pima County region. As a landfill facility, it plays a key role in the solid waste management infrastructure of southern Arizona. The facility operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste landfills and Clean Air Act regulations for landfill gas emissions. Landfills in this region typically manage waste from urban and suburban communities, with tonnage varying by service area. The NAICS code 562212 indicates a focus on solid waste landfill operations. Environmental considerations for this landfill include landfill gas collection and methane leakage management, leachate control to protect groundwater, and community proximity impacts such as traffic and odor. The facility's operational status suggests ongoing compliance with state and federal regulations to mitigate these risks.

Landfills in the Tucson area operate in a semi-arid climate, which can reduce leachate generation but still requires careful groundwater monitoring due to the region's aquifer systems. Methane capture and flaring or energy recovery are common practices to reduce greenhouse gas emissions. Community proximity and traffic from waste hauling are typical concerns for such facilities.
