Eastern Sanitary Landfill Solid Waste Management Facility (ESL) - White Marsh, Maryland Landfill

The Eastern Sanitary Landfill Solid Waste Management Facility (ESL) is a major landfill located in White Marsh, Baltimore County, Maryland, United States. Operated by Baltimore County, this facility has been accepting municipal solid waste since its opening in 1983 and is scheduled to close in 2027. As a large-scale landfill, it plays a central role in the region's waste management infrastructure. The facility operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste landfills and Clean Air Act regulations for landfill gas emissions. Landfills in Maryland must comply with state-specific environmental permits that govern leachate management, groundwater monitoring, and gas collection systems. The ESL likely employs modern landfill gas capture technology to mitigate methane emissions, though specific technical details are not disclosed. As a key waste management asset for Baltimore County, the ESL serves a densely populated suburban area near the Chesapeake Bay watershed. Its environmental significance includes managing leachate to protect local groundwater and surface water, as well as controlling odor and traffic impacts on nearby communities. The facility's closure in 2027 will require post-closure care, including long-term monitoring and gas management, in accordance with regulatory requirements.

The Eastern Sanitary Landfill is situated in a suburban area of Baltimore County, Maryland, near the Chesapeake Bay watershed. Landfills in this region face environmental challenges related to groundwater protection due to the area's hydrogeology and proximity to sensitive water bodies. Leachate management and methane gas collection are critical to prevent contamination and reduce greenhouse gas emissions. The facility's location near residential communities also necessitates careful traffic management and odor control to minimize local impacts.
