NACO CSWLF Landfill - Naco, Arizona Solid Waste Management Facility

NACO CSWLF is a landfill facility located in Naco, Cochise County, Arizona, United States. It is currently operational and serves the solid waste management needs of the local area. As a landfill, it is part of the broader waste infrastructure in the region, handling municipal solid waste disposal. The facility operates under the regulatory oversight of the United States Environmental Protection Agency (EPA), specifically under RCRA Subtitle D which governs municipal solid waste landfills. This includes requirements for liner systems, leachate management, and groundwater monitoring. The landfill also falls under the Clean Air Act regulations for landfill gas emissions, which mandate gas collection and control systems for larger facilities. As a landfill in the arid climate of Arizona, NACO CSWLF faces specific environmental considerations such as low precipitation reducing leachate generation but potential for dust and windblown litter. The facility's location near the US-Mexico border may also influence waste streams and community dynamics. Proper management of landfill gas and groundwater protection are key operational priorities.

The landfill is situated in the semi-arid climate of southeastern Arizona, where low annual rainfall reduces leachate production but increases the risk of fugitive dust and windblown debris. Groundwater protection is critical due to the region's reliance on aquifers for water supply. Proximity to the border community of Naco requires careful management of traffic, odor, and potential methane migration to ensure community safety and environmental compliance.
