Sahuarita Landfill - Municipal Solid Waste Facility in Sahuarita, Arizona

Sahuarita Landfill is an operational solid waste facility located at 16605 S. La Canada in Sahuarita, Arizona, within Pima County. As a landfill, it serves the region's municipal solid waste disposal needs, operating under the regulatory framework of the US EPA's Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs municipal solid waste landfills. The facility is classified under NAICS code 562212 (Solid Waste Landfill). Landfills in this region typically handle significant volumes of waste from the Tucson metropolitan area and surrounding communities. Operations include waste compaction, daily cover, and environmental monitoring to comply with federal and state regulations. Sahuarita Landfill plays a key role in the region's waste management infrastructure. Its location in a semi-arid climate influences leachate management and landfill gas control strategies. The facility contributes to local waste diversion goals and is subject to Clean Air Act regulations for landfill gas emissions, including methane capture and control.

The landfill operates in a semi-arid climate with low annual rainfall, which reduces leachate generation but requires careful groundwater monitoring due to the region's reliance on aquifers. Proximity to residential areas in Sahuarita necessitates odor and traffic management. Landfill gas, primarily methane, is a key environmental concern, and the facility likely employs gas collection and control systems to mitigate emissions under EPA's New Source Performance Standards.
