Hillside Landfill - Sherman, Texas Solid Waste Management Facility

Hillside Landfill is a municipal solid waste landfill located on Nelson Road in Sherman, Texas, within Grayson County. Owned and operated by WM (Waste Management), one of the largest waste management companies in the United States, the facility has been operational since 1977 and is projected to remain open until 2088. 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 EPA's Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs municipal solid waste landfills, and the Clean Air Act (CAA) landfill gas rules. These regulations require liners, leachate collection systems, and landfill gas management to minimize environmental impacts. As a large-scale landfill operated by a major national company, Hillside Landfill likely employs modern engineering controls such as composite liners, leachate treatment, and gas collection for energy recovery or flaring. Hillside Landfill serves the growing community of Sherman and surrounding areas in Grayson County. Its long operational lifespan indicates significant capacity and ongoing investment in compliance and environmental management. The facility's location in north Texas, with its relatively dry climate, may influence leachate generation rates and gas management strategies. Proper operation is essential to mitigate risks such as groundwater contamination and methane emissions.

Landfills like Hillside Landfill pose environmental risks primarily through methane leakage from decomposing waste and potential leachate contamination of groundwater. The facility's location in Grayson County, Texas, with its moderate rainfall, requires robust leachate management systems to prevent subsurface migration. Proximity to residential areas in Sherman necessitates careful traffic management and odor control. Compliance with RCRA Subtitle D and CAA landfill gas rules is critical to minimize these impacts.
