GUINDA Landfill - Woodland, California Solid Waste Management Facility

GUINDA is an operational landfill located in Woodland, California, United States. As a solid waste management facility, it handles municipal solid waste disposal for Yolo County and surrounding areas. The facility operates under the jurisdiction of California's stringent environmental regulations and the U.S. EPA's RCRA Subtitle D standards for municipal solid waste landfills. The landfill is classified under NAICS code 562212, which covers solid waste landfills. California's regulatory framework requires landfills to implement comprehensive environmental controls, including liner systems, leachate collection, and groundwater monitoring. The state also mandates landfill gas collection and control systems to mitigate methane emissions, aligning with the U.S. EPA's Clean Air Act regulations for landfill gas. GUINDA plays a critical role in regional waste management infrastructure. Its location in Yolo County places it within an agricultural and urban interface, requiring careful management of environmental impacts such as odor, traffic, and groundwater protection. The facility contributes to the state's waste diversion goals and circular economy initiatives by managing residual waste after recycling and composting efforts.

The landfill is situated in California's Central Valley, a region with a Mediterranean climate and significant agricultural activity. Proximity to groundwater aquifers necessitates robust leachate management systems to prevent contamination. Landfill gas collection is critical for reducing methane emissions, a potent greenhouse gas. Community proximity and truck traffic are key concerns, requiring effective odor control and traffic management plans.
