HOM 6 AKE <br />" <br />ALBIJQI.IERQIlE OFFIQE <br />VED <br />NOV 2 9 2p02 <br />Division of Minerals and Geology <br />~~-ar'r <br />Alan D. Cox <br />Manager -Grants 8 <br />Southwest U.S. <br />27 November, 2002 <br />Colorado Division of Minerals and Geology <br />Durango Branch Office <br />484 Tumer Drive <br />Suite F101 <br />Durango, CO 81301-7910 <br />~O; /Attn: Mr. Bob Oswald, Reclamation Specialist <br />RE: Bulldog Reclamation Project -Mineral County-Reclamation Permit #M-1977-275 <br />- Response to Ident'rfied Issues in Inspection Report dated 10/30/02 <br />Dear Mr. Oswald: <br />This letter is in response to the three issue items identified in the above referenced <br />inspection report (copy attached) documenting project site observations made by Harry <br />Posey of the Colorado DMG staff. <br />Problem /Issue #1: "9360 level appears to have a depression on it surface that will <br />hold surface water, causing it to seep into mine tailings. This apparently was not part of <br />the reclamation plan." <br />Response: We assume that you are referring to the waste rock dump rather than mine <br />tailings in reference to the 9360 level. As you are aware, reclamation activities were in <br />progress during the site inspection that included re-soiling the surface of the 9360 waste <br />rock dump and other ground shaping activities associated with that work. Since the <br />time of the inspection, we have completed additional work including re-shaping of the <br />area we believe is referenced in the inspection report. The entire surface of the 9360 <br />dump is free-draining to the north toward the recently reconstructed and riprapped <br />Windy Gulch overflow channel. The crest berm along the dump top was also <br />reconfigured and excess riprap from the recent channel construction activities was <br />placed along portions of the berm. The resultant configuration should minimize erosion <br />of the dump top surface and face and assure that any overland flow on the dump surface <br />are reported to Windy Gulch at the north end of the dump. Recent completion of soil <br />covering on the dump surface and future reestablishment of vegetation should <br />additionally minimize precipitation water infiltration into the waste rock dump. <br />~,~e <br />1~ <br />
