C-81-008. <br />telephone 97018h4-1165 <br />fu 910186-7168 Dear Mr. Ranney: <br />I am happy to report that the New Horizon Mine ias withstood a 1.36 inch, <br />area wide, rainfall event with flying colors. Elden though the 1.36 inch <br />was not a l0yr-24hr event, it was a good test on the ditches and ponds <br />that are presently in place. The rain started on October 2, 1996 at <br />approximately 6:30pm and finished cn October 3, 1996 at approximately <br />11:OOam, see Attachment 1. Rainfall records were gathered by our <br />electronic weather station at the New Horizon Mine Office. Actual <br />duratiorl of the storm was 10.50 hours and the rain was slow arrd steady. <br />NEW HORIZON 2 AREA <br />I went out several times on the 3rd and observed Pond 007 and the <br />surrounding mine permit area. I did not see any water runoff from the <br />revegetated reclaimed land. 007 East Ditch was flowing near clear water <br />at about 4 inches of depth into Pond 007. I observed the pit pump pumping <br />near clear water into Pond 007 during the stoxml. I would like to add that <br />if the pit water was not clear, the pit pump would not have been running. <br />I did not test the water quality of these two inflows however. The runoff <br />__ ..:~ _ -es~ - .~ _,.-.~~ la;~. tira~ ,iaa nu veyeta~ion growtn was <br />muddy. The muddy water was observed flowing toward the open pit, where it <br />was stored and out of harms way. During the storm, I turned the 25 HP <br />submersible pump in Pond U07 on t.o Calamity Draw. Tnis occured at Noon <br />of the 3rd, near the peak o£ the nlnoEf Elow. A water sample from the <br />pond dischaxcJe was taken and analyzed. The results passed all NPDES <br />parameters very well, thank you. Results can be seen in AttacYunenC. 2. <br />(G \DATA\WPDATA \REVISION\HARRY27.COC) 1 Of 2 <br />
