SEQUNDO Landfill - Trinidad, Colorado Solid Waste Management Facility

SEQUNDO is an operational landfill located one mile west of Segundo, near Trinidad, Colorado, in the United States. It serves the solid waste management needs of Las Animas County and the surrounding region, operating under the regulatory framework of the US EPA's RCRA Subtitle D for municipal solid waste landfills. As a landfill facility, SEQUNDO is subject to federal regulations including the Clean Air Act's landfill gas rules, which require gas collection and control systems for larger sites. The facility's NAICS code 562212 indicates it is a solid waste landfill, and its operational status suggests ongoing waste disposal activities. Typical landfill operations involve waste compaction, daily cover, and leachate management to protect groundwater. The environmental significance of SEQUNDO lies in its role as a local waste disposal solution, managing community waste while addressing potential impacts such as methane emissions and groundwater protection. Proper landfill management is critical in Colorado's semi-arid climate to minimize leachate generation and ensure long-term environmental safety.

The landfill is located in a semi-arid region of Colorado, where low precipitation reduces leachate generation but groundwater protection remains critical due to potential contamination from waste decomposition. Methane emissions from organic waste decomposition are a key environmental concern, requiring gas collection systems to mitigate greenhouse gas impacts. Proximity to rural communities necessitates careful management of traffic, odors, and dust to minimize local disturbances.
