CITY DUMP & SALVAGE #4 Landfill - Long Beach, California Solid Waste Management

CITY DUMP & SALVAGE #4 is a landfill facility located in Long Beach, California, within Los Angeles County. As an operational solid waste management site, it plays a key role in the region's waste disposal infrastructure, handling municipal solid waste from the surrounding communities. The facility operates under the regulatory framework of the US EPA, specifically RCRA Subtitle D for municipal solid waste landfills, and must comply with Clean Air Act landfill gas rules. In California, additional state-level regulations such as CalRecycle's landfill requirements apply, including methane monitoring and leachate management standards. As a landfill in a densely populated urban area, the facility's environmental significance includes managing landfill gas emissions and leachate to protect local air and groundwater quality. Its location in Long Beach, near the coast, necessitates careful environmental controls to minimize impacts on the community and surrounding ecosystems.

Landfills in coastal Southern California face unique environmental challenges, including high groundwater tables and proximity to sensitive ecosystems. Methane leakage from landfill gas is a key concern, requiring active gas collection systems to reduce greenhouse gas emissions. Leachate management is critical to prevent groundwater contamination, especially in areas with shallow aquifers. Community proximity also demands strict odor and traffic controls.
