Overview of Bridgeton Sanitary Landfill - West Lake Landfill
Last updated Nov. 9, 2018
The Missouri Department of Natural Resources’ Solid Waste Management Program (SWMP) regulates Bridgeton Sanitary Landfill. Initially permitted on Nov. 18, 1985, this landfill stopped accepting waste on Dec. 31, 2004. The landfill waste mass encompasses approximately 52 acres with approximately 240 feet below the ground’s surface and a total waste thickness of 320 feet. The waste is located in two distinct areas known as the North and South Quarries. Bridgeton Sanitary Landfill lies within the boundaries of the West Lake Landfill.
On Dec. 23, 2010, Bridgeton Sanitary Landfill first reported to SWMP that the landfill was experiencing elevated temperatures on some gas extraction wells. Since that time, a subsurface smoldering event has enveloped much of the South Quarry, as evidenced by rapid settlement, an increase in odors and leachate generation. Over the years, the landfill owner has been required to implement corrective actions to control and manage the landfill gas emissions (odors) and leachate generated from the rapid decomposition of the waste. Currently, the Bridgeton Sanitary Landfill is in a managed state. As required by the June 29, 2018 Consent Judgment, the landfill owner will continue operation, maintenance, and monitoring of the landfill infrastructure. Data collected under the Consent Judgment monitoring requirements shows the overall magnitude of the subsurface smoldering event is continuing to slowly decrease.

The West Lake Landfill site is located on 200+ acres in Bridgeton. This site is no longer accepting waste for disposal, but a portion of the facility is permitted as a solid waste processing facility that provides a service to transport municipal waste to other landfills. The entire site was listed on the federal Superfund National Priorities List in 1990 and contains several different landfill areas, also referred to as cells. Those cells fall into four general categories:
- Radiologically contaminated cells, referred to as Areas 1 and 2 of Operable Unit 1.
- Inactive cells with a mixture of debris, referred to as The Inactive Sanitary Landfill of Operable Unit 2.
- Inactive sanitary municipal solid waste cells, commonly known as Bridgeton Sanitary Landfill and referred to as the Former Active Sanitary Landfill of Operable Unit 2.
- Demolition debris cells, referred to as the Closed Demolition Landfill of Operable Unit 2.
The U.S. Environmental Protection Agency has regulating authority over Operable Unit 1 and the Inactive Sanitary Landfill of Operable Unit 2. EPA deferred regulatory authority for the other Operable Unit 2 cells to the State of Missouri in 2008. The Bridgeton Sanitary Landfill, owned by Bridgeton Landfill LLC, and is a subsidiary of Republic Services Inc., from here forward to be referred to as Bridgeton/Republic, and the Closed Demolition Landfill are regulated by the department's SWMP.
