Attached is a report of an inspection of subject licensee’s program which
we are forwarding for Headquarters enforcement.
During a routine inspection conducted on April 10, and April 23 and 24,
1974, at the licensee’s Hazelwood, Missouri, facility it was determined
that the licensee had disposed of approximately 8700 tons of leached
barium sulfate (Ba S04) which contained about 7 tons of natural uranium
(0.05 to 0.10%) to a land fill area near St. Louis. Missouri, as part of
their decommissioning of the Hazelwood site. The licensee representatives
stated that the uranium bearing residue had been mixed with approximately
5 times as much top soil, and therefore, in their opinion contained an
unlicensable percentage of uranium (less than 0.05%). The method used
for mixing was to spread the barium sulfate, which is a whitish, easily
distinguishable heavy compound,·over a considerable part of the 7 acre
Hazehrood site and then remove it along with approximately 12 to 18
inches of the surface soil. The purpose was twofold, to disperse and
dilute the uranium Ba S04 and to decontaminate the entire top surface
of the site which had be~n used for storage of uranium ore residues
since 1966.
The land fill area to which the material was disposed is one used by
