Little Dixie Landfill - Operational Landfill in Ridgeland, Mississippi, USA

Little Dixie Landfill is a municipal solid waste landfill located at 1716 N County Line Road in Ridgeland, Madison County, Mississippi, United States. Operated by Republic Services, Inc., one of the largest waste management companies in the country, the facility has been serving the region since 1979 and is projected to remain operational until 2049. As a landfill, it plays a key role in the solid waste management infrastructure of central Mississippi. The facility operates under the regulatory framework of the U.S. Environmental Protection Agency'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 proper liner systems, leachate management, and gas collection to minimize environmental impacts. The landfill's long operational history and future closure date suggest it is a significant regional disposal site, likely handling substantial tonnages of waste annually. Environmental considerations for Little Dixie Landfill include methane gas generation from decomposing waste, which is typically managed through gas collection systems to reduce greenhouse gas emissions. Leachate management is also critical to protect local groundwater resources. The facility's proximity to Ridgeland and the Jackson metropolitan area means it serves a large population, with community impacts such as traffic and odor being managed through operational practices and regulatory compliance.

The landfill is situated in Madison County, Mississippi, within the Pearl River basin, where groundwater protection is a key environmental concern. Leachate from the landfill must be carefully managed to prevent contamination of local aquifers. Methane emissions from waste decomposition are a significant factor, as methane is a potent greenhouse gas; landfill gas collection systems are typically required to mitigate these emissions. The facility's location near residential areas in Ridgeland also necessitates attention to odor control and traffic management to minimize community impacts.
