STATE OF CALIFORNIA HWY RD MAINT / CALTRANS DUMP Landfill - Los Angeles County, California

The STATE OF CALIFORNIA HWY RD MAINT / CALTRANS DUMP is a landfill facility located in Los Angeles County, California, United States. It is operated by the California Department of Transportation (Caltrans) and serves as a disposal site for waste generated from highway maintenance activities. The facility is currently operational and classified under NAICS code 562212 for Solid Waste Landfills. As a landfill in California, this facility operates under the regulatory framework of the U.S. EPA's RCRA Subtitle D for municipal solid waste landfills, as well as California's stringent state regulations for landfill operations. These regulations cover liner systems, leachate management, groundwater monitoring, and landfill gas collection and control. The facility likely handles non-hazardous solid waste from Caltrans maintenance operations, including road debris, construction materials, and vegetation. The landfill's location in Los Angeles County places it in a densely populated urban area, which necessitates careful management of environmental impacts such as odor, traffic, and potential groundwater contamination. As a public-sector landfill dedicated to highway maintenance, it plays a specific role in supporting the region's transportation infrastructure while adhering to state and federal environmental standards.

Landfills in California, particularly in urban Los Angeles County, face significant environmental challenges. Methane generation from decomposing organic waste requires active gas collection systems to mitigate greenhouse gas emissions and comply with the Clean Air Act. Leachate management is critical to prevent groundwater contamination, especially given the region's Mediterranean climate with seasonal rainfall. Proximity to communities and major highways also necessitates careful traffic management and odor control to minimize local impacts.
