Gualala Ocean Dump - Landfill in Santa Rosa, California, United States

Gualala Ocean Dump is a landfill facility located in Santa Rosa, California, United States. It is classified under NAICS code 562212 for solid waste landfills and is currently operational, serving the waste management needs of Mendocino County and surrounding areas. As a landfill, it plays a key role in the region's solid waste disposal infrastructure. The facility operates under the regulatory framework of the US Environmental Protection Agency (EPA), specifically RCRA Subtitle D which governs municipal solid waste landfills, and the Clean Air Act (CAA) which sets standards for landfill gas emissions. California also enforces stringent state-level regulations for landfill operations, including leachate management and groundwater monitoring, to minimize environmental impact. The landfill's location near the coast in a seismically active region requires careful engineering to ensure liner integrity and prevent leachate leakage. Proper management of landfill gas, which is primarily methane, is critical to reduce greenhouse gas emissions and comply with air quality standards. The facility contributes to local waste diversion goals and supports community sanitation.

The landfill is situated in a coastal region of California, which is characterized by a Mediterranean climate with wet winters and dry summers. Proximity to the Pacific Ocean and local waterways necessitates robust leachate management to prevent groundwater contamination. The area is also seismically active, requiring landfill designs that can withstand earthquakes. Landfill gas collection and control are important to mitigate methane emissions, a potent greenhouse gas, and to comply with state and federal air quality regulations.
