Owned and operated by the County of Orange - OC Waste & Recycling, this site has been in operation since 1976 and is expected to continue serving the region until 2102. As a major solid waste management facility in Southern California, it plays a key role in handling municipal solid waste from the surrounding communities. The facility operates under the regulatory framework of the United States Environmental Protection Agency (EPA) and the California Department of Resources Recycling and Recovery (CalRecycle). It is subject to RCRA Subtitle D requirements for municipal solid waste landfills, including landfill gas management and leachate control. The landfill likely employs modern engineering practices such as liner systems, gas collection, and groundwater monitoring to mitigate environmental impacts. Prima Deshecha SLF serves a densely populated region in Orange County, providing essential waste disposal services. Its long operational lifespan indicates significant capacity and community reliance. The facility's environmental significance lies in its management of landfill gas and leachate, which are critical for reducing methane emissions and protecting local groundwater resources.

The facility is situated in a region with a Mediterranean climate, characterized by dry summers and mild winters, which influences leachate generation and gas production. Proximity to residential areas and traffic corridors necessitates careful management of odor, noise, and truck traffic. Landfill gas collection systems are essential to mitigate methane emissions, a potent greenhouse gas, while leachate management is critical to prevent groundwater contamination in the area's porous soils.
