-- <br />are shown by the Operator to remain in the mining operation." Since this <br />applicant has no approved mining operation and, by his own admission, no legal <br />source of ore, he has by definition no "mineral reserves" and thus, apparently, no <br />standing for a Permit under these Rules. Nevertheless, point 4 states in part, "It <br />is the Division's view that a permit for the mill can be issued pending location of <br />an ore source...." Please clarify the Division's position on this point. <br />3. Point 10 notes the applicant's desire that the mill building "...remain as <br />a permanent feature following reclamation," with the suggestion that post-mining <br />land use might be designated as "Industrial/Commercial, " or "Residential. " The <br />first of these suggestions is in clear violation of County Zoning requirements; the <br />second, while theoretically possible, certainly stretches the definition of a <br />"residence" beyond reasonable limits (except perhaps for bats and such), We see <br />the applicant's position as an attempt to evade the substantial costs of demolition <br />and reclamation at this site and, absent some clearly identified public good to be <br />obtained, we are opposed to allowing the operator simply to walk away from this <br />facility. Please clarify the Division's policy in this area. <br />4. Point 20 states that seepage collection as described by the application is not <br />occurring and would not be necessary since the impoundment is lined. We agree, <br />provided that liner integrity is maintained. A system to assure early warning of <br />liner failure (such as the piewmeter approach identified in point 28(t) and 29(a), <br />makes excellent sense to us (see your point 26(e) also); we wonder if you agree. <br />5. Point 22 identifies the reyuirement for a containment plan for the mill <br />building. Please note that actual operating history of this facility includes spillage <br />out the man-door at the northwest corner of the building (due to a pump-seal <br />failure). Thus, planning must not focus only on the lower levels of the facility. <br />6. Point 27(e) requires "...a complete description of the decant lines and <br />underground water storage facilities." This description should include a <br />discussion of the means whereby the entrainment of tailings slimes and their <br />transport to the Hazel A adit is prevented, or at least minimized, since such <br />transport obviously bypasses the safeguards established by use of the impoundment <br />liner. Given the present condition of the decant system, it is virtually certain that <br />at least some such transport has already occurred. The Division has recognized <br />the existence of surface water escaping from this adit (refer to Point 2). We wish <br />to point out the consequent potential exposure of humans and other biota to <br />slimes~erived contaminants contained in that water. Although the Committee has <br />no data showing a present hazard, ordinary prudence dictates that this issue be <br />addressed ahead of a problem. <br />7. The above comment applies equally to Point 28(d), description of decant <br />system extension, and to Point 28(f), tailing deposition protocol and water <br />management. The use of unlined dam raises (presumably located at some <br />specified minimum distance upstream from the existing lined starter dam face) <br />
