' 13 We have an area where we have designed

17 On a water balance standpoint, the
' 18 operation of this facility is continuously requiring
19 makeup supply. We can supply back approximately 400
' 20 of the Boo gallons a minute that are required to
' 21 operate and transport the slurry from here t:o here.
22 Our objective is to isolate, as quickly
23 as we can, the free water pool from the basin of the
24 impoundment which has the drainage system ar~d the
