Marana Regional Landfill - Solid Waste Management Facility in Marana, Arizona

Marana Regional Landfill is a solid waste management facility located at 14508 West Avra Valley Road in Marana, Arizona, United States. Owned and operated by WM (Waste Management), the landfill has been operational since 2013 and serves the waste disposal needs of the greater Tucson area and Pima County. As a regional landfill, it plays a key role in the state's solid waste infrastructure. The facility operates under the regulatory framework of the U.S. Environmental Protection Agency's RCRA Subtitle D, which governs municipal solid waste landfills, and the Clean Air Act's landfill gas rules. As a modern landfill, it likely incorporates liner systems, leachate collection, and gas management technologies to meet federal and state environmental standards. Arizona's arid climate influences landfill operations, particularly regarding leachate generation and dust control. Marana Regional Landfill is significant for its capacity to handle large volumes of waste from a growing metropolitan area. Its location in the Sonoran Desert requires careful management of environmental impacts, including groundwater protection and methane gas capture. The facility contributes to WM's nationwide network of waste management services, supporting local communities with responsible waste disposal.

Located in the Sonoran Desert near Marana, Arizona, the landfill operates in an arid environment with low annual rainfall, which reduces leachate generation but increases dust management challenges. Groundwater protection is critical due to the region's aquifer systems, and the facility must comply with RCRA Subtitle D requirements for liner and leachate collection systems. Landfill gas management, including methane capture, is important for minimizing greenhouse gas emissions and complying with Clean Air Act regulations. Proximity to residential areas necessitates traffic and odor control measures.
