BOX 191 Michael6 long <br />Vietnr, CO 80860 Drvis~on Di.euor <br />RE: Cresson Mine Valley Heap Leach Pad - Phase I -Law Volume Process Fluid Collection System <br />Performance <br />Dear Mr. Hardaway: <br />We are in receipt of your correspondence dated February 27, 1995 to Mr. Mike Long concerning the below <br />listed items. We are in the process of reviewing [he information supplied us in that correspondence. We feel a <br />technical meeting between your company and the Division of Minerals and Geology may be of use in [he near <br />future. There appears to be certain areas of the permit application and commitments made in the approval that <br />are unclear. I[ is imperative that such items be made clear and all parties fully understand what is expected of <br />the operator. <br />There are two issues that require clarification a[ [his time. First, Data indicates that CC & VG has pumped <br />95,051 gallons of solution from the process fluid leak collection sump to [he pad area. While we do no[ believe <br />[hat the increased flow [ha[ the data shows is cause for concern, we do have some questions. Our inspections <br />and data you supplied us indicates that [he leak collection portion of [he facility is functioning as designed. <br />However, there is the possibility, based on pumping data, that [here is an increase in flow to the fluid collection <br />system. Our concern is this increase in Flow and whether or no[ i[ affects the desigtt and con[iaued operation of <br />the facility. <br />There appears to be a disagreement about the compliance measurement point for the maximum head in the Fluid <br />collection system. We recommend [ha[ you submit a technical revision if you believe the 2 foot head <br />requirement is too restrictive. As stated earlier, we feel that a technical meelmg [o discuss these points is <br />warranted. Please contact us at your convenience to schedule a meeting. <br />If you have any question please contact me. <br />Sincerely, ~, <br />~ji <br />Bruce Humphries <br />Minerals Program Supervisor <br />Michael Long, DMG <br />Jim Pendleton, DMG <br />Carl Mount, DMG <br />cc: Jim Komidioa, Manager, C/~ & VG <br />Berhan Keffelew DMG / <br />M:~OSSan®~AuE~~.bk <br />
