TEMPE #1 CSWLF Landfill - Tempe, Arizona Solid Waste Management Facility

TEMPE #1 CSWLF is a landfill facility located on the south side of the Salt River in Tempe, Arizona, within Maricopa County. As an operational solid waste management site, it plays a key role in the region's waste disposal infrastructure, serving the growing Phoenix metropolitan area. The facility operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste and Clean Air Act standards for landfill gas management. The facility's technical operations are typical of modern landfills in the United States, involving waste compaction, daily cover, and leachate collection systems to manage liquid byproducts. Landfill gas generated from decomposing waste is likely captured and either flared or used for energy recovery, in compliance with EPA's New Source Performance Standards. The NAICS code 562212 indicates it is classified as a solid waste landfill, handling primarily municipal solid waste. Located near the Salt River, the landfill's environmental management includes groundwater monitoring and leachate control to protect local water resources. The facility serves a densely populated urban area, requiring careful management of traffic, odor, and community impacts. Its operational status contributes to the circular economy by providing a disposal option for non-recyclable waste, while ongoing gas collection helps mitigate methane emissions.

The landfill's proximity to the Salt River necessitates robust leachate management and groundwater monitoring to prevent contamination. In the arid Arizona climate, methane generation from waste decomposition is a key concern, requiring efficient gas collection systems to reduce greenhouse gas emissions. The facility's urban location in Tempe also demands careful control of odors, litter, and traffic to minimize community impacts.
