MOLYCORP MILL SITE LF Landfill - Mountain Pass, California Solid Waste Management

MOLYCORP MILL SITE LF is a landfill facility located in Mountain Pass, California, United States. Situated approximately 8 miles west of Nipton in San Bernardino County, this operational site manages solid waste disposal for the region. The facility operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste landfills and Clean Air Act requirements for landfill gas management. As a landfill in California, MOLYCORP MILL SITE LF is subject to state-specific regulations enforced by the California Department of Resources Recycling and Recovery (CalRecycle) and local air quality management districts. The facility's NAICS code 562212 indicates it is a solid waste landfill, which typically involves waste acceptance, compaction, and daily cover operations. Landfill gas collection and leachate management are critical components of modern landfill operations to mitigate environmental impacts. The facility plays a key role in solid waste management for the Mountain Pass area and surrounding communities. Its operational status ensures continued service for waste disposal needs, while compliance with federal and state regulations helps manage environmental risks associated with landfill operations, such as methane emissions and groundwater protection.

The landfill is located in the Mojave Desert region of California, an arid environment with low rainfall, which reduces leachate generation but increases dust and air quality concerns. Proximity to groundwater sources and sensitive desert ecosystems requires careful leachate management and monitoring. Landfill gas collection systems are essential to control methane emissions, a potent greenhouse gas, and to comply with Clean Air Act regulations. Community proximity and traffic from waste hauling are additional considerations for this facility.
