Polk County SLF - Landfill in Crookston, Minnesota, United States

Polk County SLF is a municipal solid waste landfill located east of Crookston, Minnesota, in Polk County. Operational since 1975, it serves the county's waste disposal needs under the management of Polk County Solid Waste Resource Recovery. The facility is classified as a landfill within the solid waste management sector. As a landfill in the United States, Polk County SLF operates under the regulatory framework of the US EPA's Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs municipal solid waste landfills. This includes requirements for liner systems, leachate collection, groundwater monitoring, and landfill gas management. The facility's long operational history suggests it has adapted to evolving environmental standards over time. The landfill plays a key role in managing solid waste for Polk County and the surrounding region. Its location in rural Minnesota, with proximity to agricultural areas, necessitates careful management of leachate and groundwater to protect local water resources. The facility's continued operation supports community sanitation and waste diversion efforts.

Landfills in Minnesota, such as Polk County SLF, must manage landfill gas emissions, including methane, a potent greenhouse gas. Leachate management is critical to prevent groundwater contamination, especially given the region's agricultural land use and proximity to the Red River Valley. Community proximity and truck traffic are also considerations for local residents.
