Waste Mgmt of Co Denver Arapahoe Landfill - Englewood, Colorado Solid Waste Management

Waste Mgmt of Co Denver Arapahoe is a landfill facility located in Englewood, Colorado, within Arapahoe County. The facility is operational and plays a key role in managing solid waste for the Denver metropolitan area. As part of the broader Waste Management network, it handles municipal solid waste under the regulatory oversight of the Colorado Department of Public Health and Environment. The facility operates under the US EPA's RCRA Subtitle D regulations for municipal solid waste landfills, which govern liner systems, leachate management, and groundwater monitoring. Additionally, it must comply with Clean Air Act standards for landfill gas collection and control, as methane emissions are a significant environmental concern. The landfill likely employs modern gas collection systems to mitigate greenhouse gas emissions. Located in a semi-arid climate near the Rocky Mountains, the facility's environmental management focuses on preventing groundwater contamination and controlling odors. Its proximity to the Denver urban area underscores the importance of proper waste containment and community engagement. The landfill contributes to regional waste disposal infrastructure while adhering to federal and state environmental standards.

The landfill's location in Englewood, Colorado, places it in a semi-arid region with low annual precipitation, which reduces leachate generation but still requires robust groundwater monitoring due to the proximity to the South Platte River watershed. Methane leakage from landfill gas is a key concern, and the facility must comply with EPA's New Source Performance Standards for landfills. Community proximity to the Denver metro area necessitates careful traffic management and odor control measures to minimize local impacts.
