Bishop Sunland Landfill - Bishop, California Solid Waste Management Facility

Bishop Sunland is a landfill facility located at 110 Sunland Reservation Road in Bishop, California, within Inyo County. Owned by the Los Angeles Department of Water and Power (LADWP) and operated by Inyo County Integrated Waste Management, this site has been operational since 1955 and is projected to continue operations until 2064. As a municipal solid waste landfill, it serves the waste management needs of the surrounding community in the Eastern Sierra region. The facility operates under the regulatory framework of the United States Environmental Protection Agency (EPA), specifically RCRA Subtitle D for municipal solid waste landfills, as well as Clean Air Act (CAA) regulations governing landfill gas emissions. In California, the landfill is also subject to state-level regulations enforced by CalRecycle and the California Air Resources Board (CARB), which mandate landfill gas collection and control systems to reduce methane emissions. The landfill's long operational history and extended closure date indicate a significant role in regional waste management. Bishop Sunland's environmental significance lies in its management of landfill gas and leachate. As an active landfill, it must comply with EPA's New Source Performance Standards (NSPS) for landfill gas, requiring gas collection and control to mitigate methane leakage. The facility's location in the Owens Valley, with proximity to groundwater resources, necessitates robust leachate management systems to protect local water quality. The landfill provides essential waste disposal services for Inyo County and supports the region's waste diversion goals.

Bishop Sunland is situated in the Owens Valley of California, an arid region with sensitive groundwater resources. Landfill operations must address methane leakage through gas collection systems to comply with EPA and CARB regulations. Leachate management is critical to prevent groundwater contamination, given the area's hydrological connectivity. The facility's proximity to the community of Bishop also requires careful management of traffic and odor impacts.
