OF MINERALS <br />8 GEOLOGY <br />RE: Seneca II-W Mine (C-82-057) Quarterly Stockpond Inspections <br />Dear Mr. Boulay: <br />Enclosed are copies of the second quarter stockpond inspections <br />for those structures at Seneca II-W which have been constructed <br />to date. Inspections for Stockponds T-1, T-2, T-3, T-22 and T-24 <br />are included. Most of the Stockponds have been cleaned out and <br />the sediment removed from them. Stockpond T-7 is no longer a <br />stockpond and the embankment has been converted into a portion <br />of the diversion ditch within 006 Gulch which directs water into <br />the B pit pre-settling basin. T-22 will need to be reconstructed <br />entirely since portions of the dam and spillway have washed out <br />completely. Further maintenance to these areas will be done <br />later this summer. <br />Should you have any questions, please do .not hesitate to call. <br />M/i'lchae ~'~ Altavil~.
