Cooley Ranch Disposal Site - Landfill in San Bernardino County, California, USA

Cooley Ranch Disposal Site is an operational landfill located in San Bernardino County, California, United States. As a landfill facility, it plays a key role in the region's solid waste management infrastructure, accepting municipal solid waste for disposal. The site is situated in a remote area southwest of Mt. Vernon Avenue, reflecting typical siting considerations for landfill operations. Operating under the regulatory framework of the US EPA's Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs municipal solid waste landfills, the facility must comply with standards for liner systems, leachate management, and groundwater monitoring. California's stringent state regulations further enforce environmental protections, including landfill gas collection and control to reduce methane emissions. The facility's NAICS code 562212 indicates it is classified as a solid waste landfill. The environmental significance of Cooley Ranch Disposal Site lies in its role in managing waste from surrounding communities while mitigating potential impacts through engineered controls. Landfill gas management and leachate treatment are critical for reducing greenhouse gas emissions and protecting local groundwater resources. The facility's location in a desert climate may influence operational practices, such as dust control and water conservation.

The Cooley Ranch Disposal Site operates in the Mojave Desert region of San Bernardino County, an arid environment with sensitive ecosystems. Landfill gas collection systems are essential to mitigate methane leakage, a potent greenhouse gas. Leachate management is critical given the low rainfall, but any leakage could impact sparse groundwater resources. Proximity to communities and transport routes requires careful traffic and odor management to minimize local impacts.
