North Dade Landfill Miami-Dade Solid Waste Management - Operational Landfill in Miami, Florida

North Dade Landfill, operated by Miami-Dade Solid Waste Management, is a major landfill facility located at 21500 N.W. 47 Avenue in Miami, Florida. It serves the Miami-Dade County region, handling significant volumes of municipal solid waste. The facility is operational and plays a key role in the area's waste management infrastructure. As a landfill, North Dade Landfill operates under the US EPA's RCRA Subtitle D regulations for municipal solid waste landfills, which govern design, operation, and closure. The facility must comply with landfill gas management rules under the Clean Air Act, including gas collection and control systems to reduce methane emissions. Leachate management systems are also required to protect groundwater resources. The landfill's environmental significance lies in its role in managing waste from a densely populated urban area. Proper landfill gas collection helps mitigate greenhouse gas emissions, while leachate treatment safeguards local water quality. The facility's operations are subject to ongoing monitoring and regulatory oversight to minimize environmental impacts.

The North Dade Landfill is situated in a subtropical climate with high rainfall, which increases the potential for leachate generation. Effective leachate management is critical to prevent groundwater contamination in the porous limestone aquifer underlying the region. Landfill gas, primarily methane, must be captured to reduce greenhouse gas emissions and odor impacts on nearby communities. The facility's proximity to residential areas necessitates careful traffic management and odor control measures.
