John Smith Road Class III Landfill - Hollister, California Landfill Facility

John Smith Road Class III Landfill is a municipal solid waste landfill located at 2650 John Smith Road in Hollister, California, within San Benito County. Operated by Waste Connections, Inc. on behalf of San Benito County Public Works, the facility has been in operation since 1968 and is scheduled for closure in 2028. As a Class III landfill, it accepts non-hazardous municipal solid waste, serving the local community and surrounding areas. The landfill operates under the regulatory framework of the US EPA, specifically RCRA Subtitle D for municipal solid waste landfills, and California's stringent state regulations. California's landfill standards include requirements for liners, leachate collection, groundwater monitoring, and landfill gas management. The facility's long operational history suggests it has evolved to meet changing environmental standards over decades. Environmental significance includes the management of landfill gas, which is typically collected and flared or used for energy recovery to reduce methane emissions. Leachate management and groundwater protection are critical given the facility's location in a seismically active region. The landfill's closure in 2028 will require post-closure care, including continued gas and leachate management, as per regulatory requirements.

The landfill is situated in San Benito County, California, a region with a Mediterranean climate and proximity to the San Andreas Fault. Key environmental considerations include landfill gas generation (methane), which must be managed to minimize greenhouse gas emissions. Leachate production, especially during wet seasons, requires robust collection and treatment to protect groundwater. The facility's location near agricultural areas and communities necessitates careful traffic management and odor control. California's strict environmental regulations mandate comprehensive monitoring and mitigation measures for these factors.
