PICACHO MSW LANDFILL - Operational Landfill in Picacho, Arizona, USA

PICACHO MSW LANDFILL is an operational landfill located in Picacho, Arizona, within Pinal County. As a municipal solid waste facility, it manages waste disposal for the surrounding communities. The landfill is classified under NAICS code 562212, which covers solid waste landfills. The facility operates under the regulatory framework of the US EPA, specifically RCRA Subtitle D which governs municipal solid waste landfills. This includes requirements for liner systems, leachate management, and groundwater monitoring. The landfill also falls under Clean Air Act regulations for landfill gas emissions, which may necessitate gas collection and control systems depending on waste volume and age. As a landfill in the arid Southwest, water resource protection is a key environmental consideration. The facility's location in a rural area near Picacho minimizes immediate community proximity issues, though truck traffic and odor management remain operational concerns. The landfill contributes to regional waste management infrastructure, supporting Pinal County's growing population.

The landfill is situated in the Sonoran Desert, a region with low annual rainfall, which reduces leachate generation compared to wetter climates. However, groundwater protection is critical due to the area's reliance on aquifers for water supply. Landfill gas management is important to mitigate methane emissions, a potent greenhouse gas. Proximity to agricultural and rural communities requires careful traffic and odor control to minimize local impacts.
