CALMAT CLASS III DISPOSAL SITE - Landfill in Sun Valley, California, USA

CALMAT CLASS III DISPOSAL SITE is a landfill facility located at 9436 Glen Oaks Blvd in Sun Valley, California, within Los Angeles County. As a Class III disposal site, it accepts municipal solid waste and operates under the jurisdiction of the California Department of Resources Recycling and Recovery (CalRecycle) and the US EPA. The facility serves the surrounding communities in the San Fernando Valley region. The landfill operates under the regulatory framework of the US EPA's Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs municipal solid waste landfills, and the Clean Air Act (CAA) for landfill gas emissions. California's stringent environmental regulations, including the California Global Warming Solutions Act, require active landfill gas collection and control systems to mitigate methane emissions. The facility's NAICS codes (562212 and 562998) indicate it engages in solid waste landfill operations and other waste management services. As a Class III landfill, this site plays a critical role in managing the region's solid waste, diverting materials from illegal dumping and supporting public health. Its location in a densely populated urban area necessitates robust leachate management and groundwater monitoring to protect local water resources. The facility's operational status ensures continued service to the community, while compliance with evolving state and federal standards helps reduce environmental impacts.

The landfill is situated in Sun Valley, a community in the San Fernando Valley with a Mediterranean climate and proximity to the Los Angeles River watershed. Key environmental considerations include methane generation from decomposing waste, which requires active gas collection systems to reduce greenhouse gas emissions. Leachate management is critical to prevent groundwater contamination, especially given the area's alluvial soils and high water table. The facility's urban location also raises concerns about traffic, odor, and community proximity, necessitating buffer zones and monitoring programs.
