Mr. Mushinski Page 2 July 11, 2016 The Schwartzwalder Mine Plan Amendment Map shows the revised permit boundary for the Black Forest Mine is 0.53 acres, which is effectively a release of 8.07 acres from the current 8.6 acre permit area. Any change to the Black Forest Mine permit boundary must be considered under a permitting action associated with File No. M-2001-036 and cannot be processed under a permitting action for the Schwartzwalder Mine. In addition, acreage releases cannot be processed under a Technical Revision application and can only be considered pursuant to Hard Rock Rule 4.17. In order to resolve the permit boundary discrepancy, the Operator may revise the Schwartzwalder Mine Plan Amendment Map to show the Black Forest Mine and Schwartzwalder Mine permit boundaries overlap. As noted above, any additions or deletions of affected areas must be considered under separate permitting actions. 2. Under Technical Revision No. 24, the Operator is proposing to include a 0.97 acre parcel of affected land located northwest of the existing permit boundary. The Operator notified the Division the area was used to excavate borrow material to repair the Glencoe Valley Road following the flood in 2013. The Division does not consider this to be affected area associated with the Schwartzwalder Mine. Therefore, the inclusion of the 0.97 acre parcel into the Schwartzwalder Mine permit boundary is not required and may be withdrawn from further consideration under Technical Revision No. 24. 3. The Operator has stated the revised affected area for the Schwartzwalder Mine, after the addition of 0.97 acres, is 58.52 acres. The Division's records indicate the Schwartzwalder Mine is currently permitted for 61.16 acres. There is a discrepancy between the Division's records and the Schwartzwalder Mine Plan Amendment Map. Please provide a detailed accounting of the permit acreage for the Schwartzwalder Mine, including all past revisions related to additions and deletions of affected area. 4. Will the transfer of the Water Treatment Plant (WTP) require approval under the Operator's Radioactive Materials License? If so,please describe what authorizations are required and indicate if the Operator has already received approval. 5. The overall footprint of the new WTP will be smaller than the existing footprint. Will this have an impact on the amount of spent ion exchange resin from the alluvial water treatment which can be stored? 6. Please describe any safeguards which will be implemented at the new WTP to ensure that electrical service will not be interrupted resulting in the shut-down of the pumps and water treatment equipment.
