Gallo Glass / Sisk Ranch Disposal Site - Operational Landfill in Modesto, California

Gallo Glass / Sisk Ranch Disposal Site is a landfill facility located at 3666 W Service Rd in Modesto, California, within Stanislaus County. The facility is operational and serves the local community's solid waste management needs, handling municipal solid waste and potentially industrial waste as indicated by its NAICS codes (111335 for noncitrus fruit and tree nut farming, and 562212 for solid waste landfill). The facility 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 (CAA) for landfill gas emissions. California's stringent state regulations, including those from CalRecycle and the California Air Resources Board (CARB), impose additional requirements for landfill gas collection, leachate management, and groundwater monitoring to mitigate environmental impacts. As a landfill in California's Central Valley, the site plays a critical role in managing waste from Modesto and surrounding agricultural communities. Its proximity to agricultural land and groundwater resources necessitates robust environmental controls to prevent methane leakage and leachate contamination. The facility's operational status ensures ongoing waste disposal capacity for the region.

The landfill is situated in California's Central Valley, a region with intensive agriculture and significant groundwater resources. Key environmental concerns for this facility include methane emissions from decomposing waste, which contribute to greenhouse gas emissions, and leachate management to prevent groundwater contamination. The site's proximity to residential areas and agricultural land requires careful monitoring of odor, traffic, and potential air quality impacts. Regulatory oversight from the US EPA and California state agencies mandates landfill gas collection systems and groundwater monitoring to mitigate these risks.
