Lois Visco Landfill - Sun Valley, California Solid Waste Management Facility

Lois Visco Landfill is an operational solid waste landfill located at 9050 and 9116 Bradley Ave. in Sun Valley, California, within Los Angeles County. The facility is classified under NAICS code 562212 for solid waste landfills and serves the broader Los Angeles metropolitan area, one of the largest waste-generating regions in the United States. As a landfill operating in California, Lois Visco Landfill is subject to stringent state and federal regulations, including the US EPA RCRA Subtitle D standards for municipal solid waste landfills and the Clean Air Act requirements for landfill gas management. California's own Title 27 regulations impose additional requirements for liner systems, leachate collection, and groundwater monitoring to protect the state's sensitive aquifers and reduce methane emissions. The landfill plays a critical role in managing the region's waste stream, diverting materials from illegal dumping and providing a controlled disposal environment. Its proximity to residential areas in Sun Valley necessitates careful management of odors, traffic, and gas migration to minimize community impacts and align with California's ambitious climate goals.

The landfill is situated in the San Fernando Valley, a semi-arid region with a Mediterranean climate. Groundwater in the area is a concern due to historical contamination from industrial activities, making leachate management and groundwater monitoring essential. Methane generation from decomposing waste requires active gas collection systems to reduce greenhouse gas emissions and comply with California's methane reduction targets. Community proximity to the site also demands careful traffic management and odor control to maintain local quality of life.
