Occidental Disposal Site - Landfill in Sebastopol, Sonoma County, California

Occidental Disposal Site is a landfill facility located at 4985 Stoetz Ln, Sebastopol, California, within Sonoma County. The facility is currently operational and handles solid waste disposal for the surrounding region, contributing to the area's waste management infrastructure. The landfill operates under the regulatory framework of the US EPA's Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs municipal solid waste landfills, and the Clean Air Act's landfill gas emission standards. California's stringent state regulations further enforce leachate management, groundwater monitoring, and methane capture to minimize environmental impact. As a landfill in Sonoma County, Occidental Disposal Site plays a key role in managing the region's waste stream. Its location in a seismically active area necessitates robust engineering controls to ensure liner integrity and gas collection efficiency, reducing risks to nearby communities and ecosystems.

Landfills like Occidental Disposal Site must manage methane emissions through gas collection systems to mitigate greenhouse gas effects. Leachate containment and treatment are critical to prevent groundwater contamination, especially given the facility's proximity to agricultural areas and the Russian River watershed. Community proximity and truck traffic also require careful management to address odor and noise concerns.
