ST. LOUIS -- A long smoldering St. Louis County landfill has a history of methane violations.
State and county inspection reports and other public documents from the Missouri Department of Natural Resources show the landfill has been out of compliance with state regulations since the late 1990s. The issue was that the landfill was allowing excess levels of methane, a potentially dangerous gas, to seep off-site.
The St. Louis Post-Dispatch reports that the methane problems also raise questions about a possible connection to the mass of overheated waste that continues to smolder deep below the surface of the landfill.
The company says it isn’t yet ruling anything out and is working with the DNR to determine the origin of what has been called a “smoldering event.”
