New River MSW Landfill - Municipal Solid Waste Landfill in New River, Arizona

New River MSW Landfill is an operational municipal solid waste landfill located in New River, Arizona, approximately 4.3 miles west of Interstate 17. Situated in Maricopa County, this facility serves the broader Phoenix metropolitan area and surrounding communities. As a landfill, it is a key component of the region's solid waste management infrastructure, handling waste disposal for a growing population. The facility operates under the regulatory framework of the US EPA, specifically RCRA Subtitle D for municipal solid waste landfills, which governs design, operation, and closure standards. Additionally, it must comply with Clean Air Act regulations for landfill gas emissions, including gas collection and control requirements. The NAICS code 562212 indicates this is a solid waste landfill, typically involving waste compaction, daily cover, and leachate management systems. Environmental significance includes the management of landfill gas, which contains methane, a potent greenhouse gas. Proper gas collection systems help reduce emissions and may be used for energy recovery. Leachate management is critical to prevent groundwater contamination, especially given the arid Arizona climate where water resources are scarce. The facility's location near a major highway facilitates waste transport but also raises considerations for community proximity and traffic impacts.

In the arid environment of Arizona, water resources are particularly sensitive to contamination. Landfill leachate, if not properly managed, poses a risk to groundwater quality. Methane emissions from decomposing waste contribute to greenhouse gas concentrations; however, modern landfills often incorporate gas collection systems to mitigate this. The facility's proximity to residential areas in New River necessitates careful odor and traffic management to minimize community impact.
