Given the size of the waste rock at the main dump,•is it realistic to expect <br />to obtain a 95% compaction on the clay cap? <br />2. What is the average and maximum % uranium content of the waste rock taken <br />from the ore sorter reject pile that will be stockpiled at the waste dump? <br />3. The temporary waste dump is not shown on the original reclamation map. <br />4. Slopes at the main waste dump are 1:1 or less, road and creek prevent east- <br />ward expansion. <br />5. The temporary dump should be terraced, if possible, to increase slope stabi- <br />lity. <br />6. The earth berm along Ralston Creek is composed of waste rock and cement <br />blocks and appears to be inadequate. <br />7. The small earth moving operation on the north side should be described in <br />detail. <br />Protection of Hydrologic System Rule 6.2 <br />Dams <br />[dater leaving affected area <br />Surface caater monitoring <br />Diversions temporary/permanent <br />Stream channel diversions <br />Sediment Control/Maintenance of Ponds <br />Discharge structures <br />Acid or toxic materials <br />Ground caater monitoring <br />Permanent impounds <br />Haul 5 access road drainage <br />Grade <br />Drainage Ditches <br />Culverts erosion control <br />Other transport facilities <br />Other agencies or permits <br />Prasence of leachate <br />Comments: <br />1. During periods of wet weather, free standing water on the situ should be <br />collected and placed into the settling pond system. <br />2. Haul and access road drainage is poor along Ralston Creek, the berm should <br />be improved and the drainage collected. <br />3. The ore storage and loading area should be cement lined in such a way that <br />all of the ore and drainage remains on the pad. <br />4.
