RYLAND CSWLF Landfill - Tucson, Arizona Solid Waste Management Facility

RYLAND CSWLF is an operational landfill located in Tucson, Arizona, United States. Situated at the west end of 40th Street and Santa C, this facility manages solid waste for the Pima County region. As a landfill, it plays a key role in the local waste management infrastructure, handling municipal solid waste from the surrounding urban and suburban areas. The facility operates under the regulatory framework of the United States Environmental Protection Agency (EPA), specifically RCRA Subtitle D for municipal solid waste landfills and Clean Air Act (CAA) rules for landfill gas emissions. In Arizona, landfills must comply with state-level regulations that align with federal standards, including groundwater monitoring, leachate management, and methane gas collection. The NAICS code 562212 indicates this is a solid waste landfill, typically involving waste compaction, daily cover, and long-term environmental monitoring. As a landfill in the arid Southwest, RYLAND CSWLF faces unique environmental considerations, such as low precipitation reducing leachate generation but high evaporation rates. The facility's proximity to Tucson means it serves a significant population, and its operational status ensures ongoing waste disposal capacity for the region. Proper landfill gas management is critical to mitigate methane emissions, a potent greenhouse gas, and to comply with EPA regulations.

Landfills in arid regions like Tucson face lower leachate production due to minimal rainfall, but must still manage groundwater protection through liners and monitoring systems. Methane generation from decomposing waste requires gas collection systems to reduce greenhouse gas emissions and potential odor issues. Proximity to residential areas necessitates careful traffic management and dust control to minimize community impact.
