INSPECTOR'S INITIALS BK
The Division conducted a joint inspection of the site with a representative from Teller
County Government. The main purpose of the inspection was to physically visit the two Cyanide
spill outside of the lined areas.Present during the inspection were, Mr Scott Lewis of CC&V
and Miss Jane Mannon of Teller County. The physical inspection began around the second spill
area of October 31, 1999, where Mr Lewis gave a brief explanation of what took place and the
efforts the operator implemented once the spill was reported. He also pointed out the failed
reducer pipe which was located in the vicinity. The HDPE pipe has been replaced with steel
pipes and fittings. He also explained the plans that the operator has implemented and plans
to implement to avoid such failures in the future.Continued the inspection to the first spill
area of October 13, 1999. Again, Mr. Lewis briefed Miss Mannon as to the cause of the spill
outside of the lined areas. He explained, in addition to replacing the hdpe pipes with steel.
The operator is also in the process of moving most of the Header pipes up on to the leach
pad. Even if un foreseen failure takes place, the solution will be captured with in the leach
pad. While in the area, the following readings were taken from the high and low volume
collection pump systems.
HIGH VOLUME PUMPS #4 READ 18.1 FEET OF HEAD
#5 READ 19.5 FEET OF HEAD
#6 READ 23.5 FEET OF HEAD
LOW VOLUME PUMPS #1 READ .43 FEET OF HEAD
#2 READ .19 FEET OF HEAD
Mr Lewis also pointed out to a survey marker that was on top of the pregnant solution area
which shows the areas where CC&V plans to install piezometers to allow the physical
measurement of the actual solution level with out totally relying on the trancducers.He sated
that they plan to place this piezometer as soon the actual surveying is completed and
verified by the operator.Mr Lewis was informed of the extreme care that must be taken during
the drilling operation and that the Division would like to be notified so we can observe the
drilling operation.COntinued the inspection to the PHASE II and III certified areas. The
North side of the Phase II construction area, ore and leach lines have been in place and
solution was being applied while inspecting the area. No major problem noted. Operator was
granted to apply solution prior to approval of the Certification report. Approval for the
placement of leached ore was garnted during the Amendment #7 approval on January 24, 1999.
