Merrill Field Landfill - Anchorage, Alaska Solid Waste Management Facility

Merrill Field Landfill is an operational solid waste management facility located at 800 Merrill Field Drive in Anchorage, Alaska, United States. As a landfill, it provides essential waste disposal services for the Anchorage area, handling municipal solid waste generated by the local population and businesses. The facility operates under the regulatory framework of the United States Environmental Protection Agency (EPA), specifically RCRA Subtitle D for municipal solid waste landfills, and must comply with Clean Air Act landfill gas rules. In Alaska, landfills face unique challenges due to permafrost and cold climate conditions, which influence leachate management and gas collection systems. The facility's NAICS codes indicate involvement in highway and street construction (237310), other support activities for air transportation (488190), solid waste landfill (562212), and regulation of solid waste management (926120), suggesting a multi-faceted operation. Merrill Field Landfill plays a critical role in Anchorage's waste management infrastructure, serving a community of nearly 300,000 residents. Its location near Merrill Field Airport requires careful coordination with aviation activities. The landfill's environmental significance includes managing methane emissions through gas collection systems and protecting groundwater through leachate controls, which are standard for modern landfills in the United States.

Anchorage's subarctic climate with permafrost presents unique challenges for landfill operations, including leachate management and gas collection efficiency. The facility's proximity to Merrill Field Airport and residential areas necessitates strict odor and traffic controls. Landfill gas, primarily methane, must be captured to reduce greenhouse gas emissions, and leachate must be treated to prevent groundwater contamination in the sensitive Cook Inlet watershed.
