SD City Miramar Landfill - San Diego, California Solid Waste Management Facility

SD City Miramar Landfill is an operational landfill located at 5180 Convoy Street in San Diego, California. As a key solid waste management facility in the region, it processes municipal solid waste and operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste landfills and Clean Air Act landfill gas rules. The facility operates within California's stringent environmental regulations, which require comprehensive landfill gas collection and control systems to mitigate methane emissions. Leachate management systems are also mandated to protect groundwater resources, given the proximity to urban areas and the local hydrogeology. The landfill's scale is typical for a major metropolitan area like San Diego, handling significant tonnage annually. Environmental significance includes the management of landfill gas, which can be converted to energy, reducing greenhouse gas emissions. The facility's location in a densely populated area necessitates careful community engagement and traffic management. Its role in San Diego's waste infrastructure is critical for public health and environmental protection.

San Diego's Mediterranean climate with low annual rainfall reduces leachate generation compared to wetter regions, but the proximity to the Pacific Ocean and coastal aquifers requires robust groundwater monitoring. Landfill gas collection systems are essential to control methane, a potent greenhouse gas, and may be used for energy recovery. Community proximity and truck traffic are key environmental considerations for this urban landfill.
