LandComp Landfill - Ottawa, Illinois | Republic Services Landfill

LandComp Landfill is a municipal solid waste landfill located at 2840 E. 13th Road in Ottawa, LaSalle County, Illinois. Owned and operated by Republic Services, Inc., one of the largest waste management companies in the United States, the facility has been operational since 1998 and is projected to continue operations until 2061. As a landfill serving the region, it plays a key role in managing solid waste from surrounding communities. As a Subtitle D landfill under the US EPA's Resource Conservation and Recovery Act (RCRA), LandComp Landfill is subject to federal and state regulations governing liner systems, leachate management, groundwater monitoring, and landfill gas control. The facility likely employs modern landfill technologies such as composite liners, leachate collection systems, and gas extraction wells to mitigate environmental impacts. Illinois regulations require compliance with state solid waste management rules, including financial assurance for closure and post-closure care. The landfill's long operational lifespan indicates significant capacity and regional importance. Proper management of landfill gas, which contains methane, is critical for reducing greenhouse gas emissions and may include energy recovery or flaring. Leachate management and groundwater protection are also key environmental considerations, given the facility's location in a rural area with potential groundwater resources. The landfill serves the Ottawa area and contributes to the state's waste management infrastructure.

Landfills in Illinois, like LandComp, must manage landfill gas (primarily methane) to reduce greenhouse gas emissions and odor. Leachate, a liquid that percolates through waste, requires careful collection and treatment to prevent groundwater contamination. Proximity to the Illinois River and agricultural areas underscores the importance of robust environmental controls. Community concerns often include traffic from waste hauling vehicles and potential air quality impacts. Regulatory oversight by the Illinois Environmental Protection Agency ensures compliance with RCRA Subtitle D and state-specific requirements.
