LAKE CITY Landfill - Hinsdale County, Colorado Solid Waste Management Facility

LAKE CITY is an operational landfill located in Hinsdale County, Colorado, United States. As a solid waste management facility, it provides essential waste disposal services to the surrounding area, handling municipal solid waste under the jurisdiction of the US EPA and Colorado state environmental agencies. The facility 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 management, groundwater monitoring, and landfill gas control. The landfill's NAICS code 562212 indicates it is a solid waste landfill, typically involving waste compaction and daily cover practices. As a landfill in a rural, mountainous region of Colorado, LAKE CITY must manage environmental considerations such as groundwater protection in a high-altitude setting and potential methane generation from decomposing waste. Proper gas collection and leachate management are critical to minimizing environmental impact and ensuring compliance with Clean Air Act landfill gas rules.

Landfills like LAKE CITY pose environmental risks primarily through methane emissions and leachate generation. Methane, a potent greenhouse gas, is produced during anaerobic decomposition and must be collected or flared to reduce atmospheric release. Leachate, a contaminated liquid, requires careful management to prevent groundwater contamination, especially in areas with shallow water tables or sensitive ecosystems. The facility's location in Colorado's mountainous terrain may involve additional considerations for runoff and wildlife proximity.
