Eastern Regional MSW Landfill - Municipal Solid Waste Landfill in Elfrida, Arizona

Eastern Regional MSW Landfill is a municipal solid waste landfill located 1 mile north of Elfrida, Arizona, in Cochise County. The facility is operational and serves the region's solid waste management needs under the regulatory oversight of the US EPA and Arizona Department of Environmental Quality. As a landfill, the facility is subject to RCRA Subtitle D regulations for municipal solid waste, including requirements for liner systems, leachate collection, and groundwater monitoring. The landfill likely operates under state permits that enforce compliance with federal standards for landfill gas management and methane emission controls. The facility plays a key role in managing waste from surrounding communities in southeastern Arizona. Its location in a rural area may influence operational considerations such as transportation distances and community proximity. Proper management of landfill gas and leachate is essential to minimize environmental impacts on local groundwater and air quality.

The landfill is situated in a semi-arid region of southeastern Arizona, where groundwater resources are critical for local agriculture and ecosystems. Leachate management is a key environmental concern, as any leakage could affect shallow aquifers. Landfill gas, primarily methane, must be collected and controlled to reduce greenhouse gas emissions and odor impacts on nearby communities. The facility's rural setting may also involve considerations for wildlife and habitat disturbance.
