Graham County Central Landfill is an operational solid waste facility located in Central Heights, Graham County, Arizona, United States. It serves as a municipal solid waste landfill for the surrounding area, managed under the regulatory framework of the US EPA's Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs non-hazardous solid waste landfills. As a landfill, the facility is subject to federal and state regulations including landfill gas management and leachate control. The NAICS code 562212 indicates it operates as a solid waste landfill, typically involving waste disposal, compaction, and daily cover. The facility's scale is likely medium-sized, serving Graham County's population and waste generation needs. The environmental significance of Graham County Central Landfill includes its role in managing local solid waste while mitigating potential impacts such as methane emissions and groundwater contamination. Proper operation under RCRA Subtitle D ensures liner systems, leachate collection, and gas monitoring are in place to protect the surrounding environment and community.

Located in southeastern Arizona, the landfill operates in a semi-arid climate with low annual rainfall, reducing leachate generation but requiring careful water management. The proximity to groundwater sources necessitates robust liner and leachate collection systems to prevent contamination. Methane gas from waste decomposition is typically managed through passive or active collection systems to minimize greenhouse gas emissions and comply with Clean Air Act landfill gas rules.
