Crook County Landfill - Prineville, Oregon Municipal Solid Waste Landfill

Crook County Landfill is a municipal solid waste landfill located at 5601 SW Houston Lake Road in Prineville, Oregon, United States. Owned and operated by Crook County, the facility has been operational since 1973 and is projected to remain open until 2050. As a landfill serving a rural county in central Oregon, it plays a key role in managing the region's solid waste. The landfill operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA) and the Oregon Department of Environmental Quality. It is subject to RCRA Subtitle D requirements for municipal solid waste landfills, including liner systems, leachate management, and groundwater monitoring. Landfill gas management is also regulated under the Clean Air Act, with potential for gas collection and utilization. Crook County Landfill provides essential waste disposal infrastructure for the local community. Its long operational lifespan and county ownership indicate a stable facility that supports regional waste management needs. Proper management of environmental controls, such as leachate and gas, is critical to minimizing impacts on the surrounding environment.

The landfill is located in central Oregon, a region with semi-arid climate and proximity to groundwater resources. Leachate management is a key environmental concern, as it must be collected and treated to prevent contamination of local aquifers. Landfill gas, primarily methane, is generated from decomposing waste and requires collection or flaring to reduce greenhouse gas emissions. The facility's location near Prineville also raises considerations for community proximity and traffic impacts from waste hauling.
