COOLIDGE NO 2 CSWLF Landfill - Coolidge, Arizona Solid Waste Management Facility

COOLIDGE NO 2 CSWLF is an operational landfill located in Coolidge, Arizona, within Pinal County. As a solid waste management facility, it handles municipal solid waste for the surrounding community. The facility is situated approximately 1 mile north of AZ 287 on Christ Road, serving as a key waste disposal site in the region. The landfill operates under the regulatory framework of the US EPA, specifically RCRA Subtitle D which governs municipal solid waste landfills. This includes requirements for liner systems, leachate management, and groundwater monitoring. The facility's NAICS code 562212 indicates it is classified as a solid waste landfill, aligning with typical operational standards for such sites in the United States. Environmental considerations for this landfill include methane gas generation from decomposing waste, which is often managed through gas collection systems to reduce greenhouse gas emissions. Leachate management is also critical to prevent groundwater contamination, especially given the arid climate of Arizona. The facility's location in a rural area may reduce community proximity concerns, but traffic from waste hauling vehicles remains a factor.

The landfill is located in the Sonoran Desert region of Arizona, characterized by low rainfall and high evaporation rates. This arid climate reduces the volume of leachate generated but also means that any groundwater contamination could persist longer due to slow natural attenuation. Methane emissions from the landfill contribute to local greenhouse gas levels, and proper gas collection is essential. The facility's proximity to agricultural areas and sparse population minimizes direct community impact, but dust and odor control remain operational priorities.
