From 1962 to 1964, the Atomic Energy Commission tried to sell the waste material at the St. Louis Airport Storage Site.  In 1966, much of the material was sold to the Continental Mining and Milling Company (CMMC).  CMMC began moving some of the residues to the Hazelwood Interim Storage Site (HISS) at 9200 Latty Avenue, Hazelwood, Missouri, about 1/2 a mile north of the St. Louis Airport.  During transport, many properties in Hazelwood and Berkeley were contaminated by spillage.  The Hazelwood Interim Storage Site was placed on the Superfund National Priority List in 1989.  Latty Avenue is now one of the U.S. Army Corps of Engineer’s FUSRAP sites.
