MO HCR37

West Lake Landfill, located north and west of Lambert-St. Louis International Airport, received approximately 8,700 tons of low-level radioactive material (leached barium sulfate) mixed with 39,000 tons of soil in 1973.

The U.S. EPA added the landfill to its National Priorities List in 1990 and selected a final cleanup remedy in its 2008 Record of Decision, which includes a five-foot engineered cap, groundwater monitoring, surface water controls, and landfill gas monitoring.

Excavation alternatives pose risks including exposure to contaminated waste, increased truck traffic hauling radioactive waste through communities, bird strike hazards to nearby Lambert Airport, and potential traffic accidents.

The resolution requests that the 2008 Record of Decision be adopted as the official remedy and implemented expeditiously, as no long-term cleanup has been completed despite decades of testing and analysis.

The Chief Clerk is instructed to send copies of this resolution to U.S. Senate and House leadership, the EPA Administrator, and Missouri's Congressional delegation.
