GREGG AND W.T.
- CROW, September 16, 1980 Gentlemen:
The purpose of this letter is to document the referenced phone call wherein you were informed of a situation which occurred at this facility on Saturday, September 13, 1980.
While we do not consider this to be a reportable incident.
-under 10CFR, we feel that you should be aware of the situation, should any questions arise about it in the future.
On the morning of September 13, 1980, one of our Nuclear.
and Industrial Safety personnel made a routine inspection?? 1 of the tank being used for storage of liquids from the lagoon system. (The use of this tank.was authorized by Amendment No. 6 to License SNM-777.)
On arriving at the tank location, he saw that the containment bcsin surround-ing it held several inches of liquid.
Further inspection showed that the liquid was coming from the tank via a hose which had been placed in it for the purpose of pumping out liquids to be processed through the evaporation system.
Action was immediately taken to stop the flow of liquid, and to pump it back into the tank.

r Subsequent analysis of the situation indicates that:
a)
The tank contained approximately 350,000 gallons of liquid (out of a 500,000 gallon capacity),
h b) between 25,000 and 40,000 gallons of liquid had been transferred to the containment basin when it was detected, h
c) the flow apparently started when,a siphon action was inadvertently and unknowingly created on Friday, September 12.
Other pertinent information is as follows:
p a)
As the containment basin was specifically designed to hold the entire contents of the tank, an L
unintentional release to the environment would not b
have occurred even if the drainage had gone undetected; b) before the system was put into use in early 1979, the containment basin,-which is lined with.030" thick
.Hypalon, was leak tested and found to be sound; c) as we periodically have to pump rain water accumu-lations out of the basin, the liner still appears to.
be sound.
However, since the possibility exists that there are small punctures or cuts in the liner, we cannot totally rule out some leakage during this occurance.
We will closely monitor the nearby test wells for any evidence of such.
If you desire any further information on this matter, please contact me.
