JOHNSTON SLF Landfill - Larimer County, Colorado Solid Waste Management

JOHNSTON SLF is a landfill facility located in Larimer County, Colorado, United States. It is currently operational and classified under NAICS code 562212 for solid waste landfill operations. The facility plays a role in managing municipal solid waste for the surrounding area. As a landfill in the United States, JOHNSTON 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. State-level regulations in Colorado further enforce standards for landfill design, operation, and closure. Typical landfill operations include waste compaction, daily cover, and leachate management to minimize environmental impact. The facility's location in Larimer County places it within a region with varied geography, including proximity to the Rocky Mountains. Landfills in this area must manage leachate carefully to protect groundwater resources. The facility contributes to local waste management infrastructure, serving residential and commercial waste generators in the region.

Landfills like JOHNSTON SLF require careful management of landfill gas, which primarily consists of methane and carbon dioxide. Methane is a potent greenhouse gas, and many landfills in the United States are required to collect and control gas emissions under the Clean Air Act. Leachate management is also critical to prevent groundwater contamination, especially in areas with high precipitation or shallow water tables. The facility's location in Colorado, with its semi-arid climate, may reduce leachate generation but still requires robust liner and collection systems.
