(Page 2) MINE ID # OR PROSPECTING ID #: M-1985-043 INSPECTION DATE: F-7n-n2 INSPECTOR'S INITIALS: ~.(L OBSERVATIONS Completed a partial inspection of this operation to review the condition of the sedimentation retention system. Mr. Tom Smith and Mr. Telly Labus participated in the inspection. There are suppose to be 3 retention ponds adequately sized to contain runoff from the 2 year 24 hour precipitation event. Expected runoff from the design event is anticipated to be 3.0 acre-feet. As designed and constructed, pond number one, which is located at the southern boundary of the permit, should contain 2.26 acre•feet of runoff. Pond number two, just north of pond one (at the toe of the highwalp, is expected to contain 3.02 acre-feet of runoff. And, pond number three, which has been located northwest (upgradient) of pond number two, is expected to contain .40 acre-feet of runoff. Total capacity of all three ponds is calculated to be 5.68 acre-feet of runoff (slightly more than the expelled runoff from the 10 year 24 hour precipitation event of 5.6 acre-feet). The size of pond number one has not changed. The operator just recently cleaned it out so the capacity is expected to be 2.26 acre-feet. Pond number two has been moved to the north because the highwall has moved. Currently, its capacity is unknown. This is noted as a problem on page 3 of this report. The operator shall be required to submit a revised Mining plan map showing the new location and the constructed dimensions of the pond. It must be capable of containing 3.02 acre-feet, or more, of runoff from the evaluated 55 acre watershed. Pond number three has been totally eliminated because the area is being used to stockpile processed material. Having two ponds capable of containing all the runoff from the 2 year 24 hour event (the design event) there is probably no need for the third pond. However, three ponds were approved in TR-001 and the only way to eliminate one of them is to submit another Technical Revision. But, as history has shown, this area is subject to occasional heavy precipitation events and, it would provide a larger safety margin if three, or more, ponds were available to capture stormwater runoff from the disturbed areas. For now, the elimination of pond three is noted as a problem on page 3 of this report. The operator shall be required to submit a technical revision to eliminate pond number three (and a very good reason to do so) or re-excavate the previous pond, or construct a new pond with similar dimensions at a location which will capture stormwater runoff exactly like the approved pond number three. The correMive action dates for both noted problems shall be 60 days, or September 6, 2002. Note that Red Creek is not flowing at this time. No other problems observed.
