HOUGHTON / IRVINGTON CSWLF - Landfill in Tucson, Arizona, United States

HOUGHTON / IRVINGTON CSWLF is an operational landfill located in Tucson, Arizona, within Pima County. It manages solid waste for the region, operating under the regulatory framework of the US EPA's Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs municipal solid waste landfills. The facility is classified under NAICS code 562212 for solid waste landfill operations. As a landfill in the United States, this facility must comply with federal regulations including landfill gas collection and control requirements under the Clean Air Act, as well as state-level environmental permits. Typical operations involve waste compaction, daily cover, leachate management, and gas monitoring to mitigate methane emissions and groundwater impacts. The facility plays a key role in the Tucson metropolitan area's waste management infrastructure. Its operational status ensures continued service for local communities, while adherence to regulatory standards helps minimize environmental risks associated with landfill operations, such as methane leakage and leachate migration.

Located in the Sonoran Desert of southern Arizona, the landfill operates in an arid climate with low annual rainfall, which reduces but does not eliminate leachate generation risks. Groundwater protection is critical due to the region's reliance on aquifers for water supply. Landfill gas management, including methane capture, is important for mitigating greenhouse gas emissions. Proximity to Tucson's urban area necessitates careful traffic management and odor control to minimize community impacts.
