McCollum Disposal Site - Operational Landfill in Visalia, California

McCollum Disposal Site is an operational landfill located at 10001 248 Avenue in Visalia, California, within Tulare County. It serves as a solid waste management facility for the region, handling municipal solid waste under the regulatory oversight of the US EPA and the California Department of Resources Recycling and Recovery (CalRecycle). As a landfill, McCollum Disposal Site operates under Subtitle D of the Resource Conservation and Recovery Act (RCRA), which sets standards for municipal solid waste landfills, including liner systems, leachate collection, and groundwater monitoring. The facility also complies with the Clean Air Act's landfill gas regulations, which require gas collection and control systems to reduce methane emissions. California's stringent environmental laws further enforce rigorous operational practices. The landfill plays a critical role in managing waste from Visalia and surrounding communities in Tulare County. Its operations are subject to ongoing environmental monitoring to mitigate impacts on local air and water quality. The facility's location in California's Central Valley, an agriculturally intensive region, underscores the importance of proper waste management to protect groundwater resources and reduce greenhouse gas emissions.

The Central Valley's agricultural economy and Mediterranean climate create specific challenges for landfill operations, including potential groundwater contamination from leachate and methane emissions from decomposing waste. Proximity to residential areas in Visalia necessitates careful management of traffic, odor, and gas migration. California's regulatory framework, including the California Global Warming Solutions Act, drives enhanced landfill gas capture and renewable energy generation at many facilities.
