USMC / 29 Palms Disposal Site - Landfill in Twentynine Palms, California

The USMC / 29 Palms Disposal Site is a landfill located on the Marine Corps Base in Twentynine Palms, San Bernardino County, California. It is an operational facility that handles solid waste generated by the base and surrounding areas, classified under NAICS code 562212 for solid waste landfills. As a landfill in the United States, this facility operates under the US EPA's Resource Conservation and Recovery Act (RCRA) Subtitle D, which sets standards for municipal solid waste landfills, including liner systems, leachate management, and groundwater monitoring. Additionally, it must comply with Clean Air Act regulations for landfill gas emissions, which require gas collection and control systems for larger landfills. The facility plays a critical role in managing waste from the Marine Corps installation, supporting the base's operational readiness and environmental compliance. Its location in the Mojave Desert presents unique challenges for leachate management and groundwater protection due to arid conditions and sensitive desert ecosystems.

Located in the Mojave Desert, the landfill faces environmental considerations typical of arid regions, including limited water resources and sensitive desert habitats. Leachate management is critical to prevent groundwater contamination in a region where aquifers are vital for local water supply. Landfill gas, primarily methane, must be managed to reduce greenhouse gas emissions and comply with Clean Air Act standards. Proximity to the Marine Corps base also requires careful traffic and odor management to minimize community impact.
