Overview
West Miramar SLF is an operational landfill in San Diego, California, operated by the City of San Diego since 1983. It serves the region's solid waste management needs under US EPA RCRA Subtitle D regulations.
West Miramar SLF is a landfill facility located at 5180 Convoy Street in San Diego, California, United States. Operated by the City of San Diego, the landfill has been in operation since 1983 and is currently open, with a planned closure in 2025. As a municipal solid waste landfill, it plays a key role in managing the region's waste disposal requirements. The facility operates under the regulatory framework of the US EPA's Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs municipal solid waste landfills. This includes requirements for liner systems, leachate collection, groundwater monitoring, and landfill gas management. The landfill's location in San Diego, a major urban center in California, means it must comply with state-level regulations from the California Department of Resources Recycling and Recovery (CalRecycle) and local air quality management districts. As a landfill, West Miramar SLF contributes to the environmental challenges of methane emissions from decomposing waste and potential groundwater impacts from leachate. Proper gas collection and leachate management systems are critical to mitigating these risks. The facility's closure in 2025 will require post-closure care, including monitoring and maintenance, to ensure long-term environmental protection.
Environmental context
Landfills like West Miramar SLF are significant sources of methane, a potent greenhouse gas, due to anaerobic decomposition of organic waste. Effective landfill gas collection systems are essential to capture methane for energy recovery or flaring. Leachate, the liquid that percolates through waste, must be managed to prevent groundwater contamination, especially in areas with high water tables or proximity to sensitive ecosystems. The facility's location in urban San Diego also raises considerations for community proximity, odor control, and traffic from waste hauling vehicles.
