BENSON MSW LANDFILL - Municipal Solid Waste Landfill in Benson, Arizona

BENSON MSW LANDFILL is an operational municipal solid waste landfill located in Benson, Arizona, within Cochise County. The facility is situated approximately 0.3 miles north of Interstate 10 on Ocotillo Road, serving the local community's solid waste disposal needs. As a landfill, it operates 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's NAICS code 562212 indicates it is classified as a Solid Waste Landfill. In Arizona, landfills must comply with state and federal regulations, including groundwater monitoring, leachate management, and landfill gas control. The arid climate of southeastern Arizona reduces certain environmental risks, such as leachate generation, but methane management remains a key operational focus. BENSON MSW LANDFILL plays a critical role in managing solid waste for Benson and surrounding areas in Cochise County. Its proximity to Interstate 10 facilitates waste transport, while its location in a sparsely populated region helps mitigate community proximity concerns. The facility's operational status ensures ongoing waste disposal capacity for the region.

The landfill operates in a semi-arid region of southeastern Arizona, where low precipitation reduces leachate generation but does not eliminate the need for proper liner and collection systems. Methane generation from decomposing waste requires gas collection or flaring to minimize greenhouse gas emissions. Groundwater monitoring is essential due to the potential for contamination from leachate, though the dry climate lowers overall risk. The facility's distance from dense residential areas reduces community exposure to odors and traffic.
