Operational since 1982, it is owned by the Jefferson Parish Department of Environmental Affairs and operated by Waste Connections, Inc. The facility plays a key role in managing solid waste for the region, with a projected closure year of 2050. The landfill operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste and Clean Air Act landfill gas rules. As a landfill in Louisiana, it is subject to state environmental regulations and likely employs standard practices such as liner systems, leachate collection, and gas management to mitigate environmental impacts. Jefferson Parish SLF serves a densely populated area near New Orleans, providing essential waste disposal services. Its long operational history and extended lifespan highlight its importance to local waste management infrastructure. The facility's proximity to the Mississippi River and urban areas necessitates careful environmental monitoring, particularly for groundwater and air quality.

The landfill's location near the Mississippi River and the Gulf Coast presents environmental considerations for leachate management and groundwater protection. Louisiana's humid subtropical climate can increase leachate generation, requiring robust collection and treatment systems. Landfill gas, primarily methane, must be captured to reduce greenhouse gas emissions and comply with Clean Air Act regulations. Proximity to communities in Jefferson Parish also necessitates odor control and traffic management to minimize local impacts.
