Carroll-Grayson-Galax SW Authority (CGGSWA) Regional Landfill - Hillsville, Virginia Solid Waste Management

The Carroll-Grayson-Galax SW Authority (CGGSWA) Regional Landfill is located at 162 Landfill Road in Hillsville, Carroll County, Virginia. Operated by the Carroll-Grayson-Galax Regional Solid Waste Authority, this facility has been accepting municipal solid waste since 1987 and is projected to remain open until 2065. It serves the communities of Carroll County, Grayson County, and the city of Galax, functioning as a key regional disposal site. As a Subtitle D landfill, the facility operates under the US EPA's Resource Conservation and Recovery Act (RCRA) regulations, which govern design, operation, and closure standards for municipal solid waste landfills. These standards include requirements for liner systems, leachate collection, groundwater monitoring, and landfill gas management. The landfill's long operational timeline suggests it is a significant regional asset with substantial remaining capacity. Environmental management at the site focuses on controlling leachate to protect local groundwater and managing landfill gas to reduce methane emissions. The facility's location in rural Virginia, with proximity to the Blue Ridge Mountains, underscores the importance of proper waste containment in a region with sensitive ecosystems. Community engagement and traffic management are also key operational considerations.

The landfill's environmental context involves managing leachate to prevent groundwater contamination in the Carroll County area, which features rolling hills and water resources. Landfill gas collection systems are critical for mitigating methane emissions, a potent greenhouse gas. Proximity to rural communities requires careful traffic and odor management to minimize local impacts.
