ANTONITO Landfill - Solid Waste Management in Antonito, Colorado

ANTONITO Landfill is an operational solid waste management facility located approximately 4 miles west and 1 mile south of Antonito, Colorado, in Conejos County. As a landfill, it serves the local community by providing disposal capacity for municipal solid waste generated in the region. The facility is classified under NAICS code 562212, which covers solid waste landfills. The landfill operates under the regulatory framework of the US Environmental Protection Agency's Resource Conservation and Recovery Act (RCRA) Subtitle D, which sets standards for municipal solid waste landfills, including liner systems, leachate management, and groundwater monitoring. Additionally, the Clean Air Act (CAA) requires landfills to collect and control landfill gas emissions to reduce methane and other air pollutants. These regulations ensure environmental protection and public health safeguards. As a small to medium-scale facility in rural Colorado, ANTONITO Landfill plays a key role in managing waste from the local community. Its location in a semi-arid region with low precipitation reduces leachate generation risks, but groundwater monitoring remains important due to the proximity of agricultural areas. The landfill's operational status contributes to the region's waste management infrastructure, supporting public health and environmental sustainability.

The landfill is situated in a semi-arid region of southern Colorado, where low annual precipitation reduces the potential for leachate generation compared to wetter climates. However, groundwater monitoring is critical due to the presence of agricultural activities and shallow aquifers in the area. Landfill gas management, including methane collection and control, is required under the Clean Air Act to mitigate greenhouse gas emissions and odor impacts. The facility's rural location minimizes community proximity issues, but traffic from waste hauling vehicles may affect local roads.
