Little Rock City SW Landfill - Municipal Solid Waste Landfill in Little Rock, Arkansas

Little Rock City SW Landfill is a municipal solid waste landfill located at 10803 Ironton Cut Off Road in Little Rock, Pulaski County, Arkansas. Operated by the City of Little Rock, the facility has been in operation since 1976 and is currently open, with a projected closure year of 2073. It serves as a key component of the city's solid waste management infrastructure. As a Subtitle D landfill under the U.S. EPA's Resource Conservation and Recovery Act (RCRA), the facility must comply with federal regulations for liner systems, leachate management, and groundwater monitoring. The landfill likely employs modern practices such as daily cover, gas collection, and stormwater controls to mitigate environmental impacts. Arkansas's regulatory framework, enforced by the Arkansas Department of Energy and Environment, ensures adherence to state and federal standards. The landfill plays a vital role in managing the solid waste generated by the Little Rock metropolitan area. Its long operational lifespan (1976-2073) indicates a significant capacity and long-term commitment to regional waste disposal. Proper management of landfill gas and leachate is critical to minimizing methane emissions and protecting local groundwater resources.

The landfill is situated in central Arkansas, a region with a humid subtropical climate and significant annual rainfall, which increases the potential for leachate generation. Proximity to the Arkansas River and local aquifers necessitates robust groundwater monitoring and leachate collection systems. Methane emissions from decomposing waste are a concern, and the facility likely employs gas collection systems to reduce greenhouse gas emissions and potentially generate energy. Community proximity and truck traffic are also important considerations for local residents.
