Dear Mr. Mason:
The Permits and Engineering Unit has completed a preliminary engineering review of the
subject application.
The following items must be addressed before we can complete our review. Please note that
these items must be received by August 19, 1990, in order to prevent your project from being
returned as incomplete:
1) The settling basins should be sized to porvide at least two (2) feet of freeboard.
Please show a minimum of two (2) feet of freeboard on the plans.
2) Provide the depths of the settling ponds. If the ponds are to be excavted into
bedrock or into the water table then a liner of at least 1 x 10-7 cm/sec should be
provided. This should be specified on the plans.
3) The pump should be sized to provide 50 gpm at 30 feet of TDH. The friction
loss in 1.5 inch pvc pipe is approximately 10 feet per 100 feet of length and with
the static head of 20 feet the TDH required is 30 feet negelecting pipe fittings.
If you have any questions concerning this matter, please call me at 919/ 733-5083.

PLAN OF OPERATION
MASON GEM MINE
TOPTON, NORTH CAROLINA
When the sluicing system is operational, the pump is turned on. The pump over-
flow water runs through the wooden flume. The dirt from the ruby mine is introduced
into the flume and washed by the water into the settling tanks. The dirt settles
to the bottom of the tanks and the clean water overflows into the pump storage
tank where it is pumped back into the flume.
When the settling tanks are filled up three (3) feet from the bottom, the remain-
ing water in the settling tank should be pumped into the pump storage tank and the
sediment removed. (The sluicing process must be stopped during the sediment
removing process). The sediment which is removed will be placed into buckets and
recycled thru the sluicing operation.
