Long Valley / McGee Creek Dump - Operational Landfill in Sacramento, California

Long Valley / McGee Creek Dump is an operational landfill located on McGee Creek Road in Mono County, California, serving the broader Sacramento region. As a solid waste management facility, it handles municipal solid waste and is classified under NAICS code 562212 for Solid Waste Landfills. The facility operates under the regulatory framework of the US Environmental Protection Agency, including RCRA Subtitle D for municipal solid waste landfills and Clean Air Act regulations for landfill gas emissions. California's stringent state-level environmental standards further govern leachate management, groundwater monitoring, and methane control. This landfill plays a key role in regional waste disposal for Mono County and surrounding areas. Its location in a rural, seismically active region requires careful environmental management to protect local water resources and air quality. The facility contributes to California's integrated waste management system, which emphasizes diversion and landfill gas capture.

The landfill is situated in a rural area of Mono County, near the Sierra Nevada mountain range. The region's hydrology includes sensitive groundwater basins and surface waters that require robust leachate management systems to prevent contamination. Methane generation from decomposing waste necessitates active gas collection and flaring or energy recovery to reduce greenhouse gas emissions. Proximity to natural habitats and recreational areas also demands careful odor and traffic management to minimize community and ecological impacts.
