RPM,Inc. March 25, 2019 Re: Bullion King Mine Reclamation Project, File No. M-2019-011, 110(2) Application Adequacy Comments, Response#1 1. Pursuant to Rule 6.3.5(2)(a), outline and label the entire permit boundary on a Mine Plan Map. Response: We have included a new set of replacement maps (Fig 1., Site Map, Fig 2., Existing Conditions, Fig 3.,Proposed Condition) 2. The two existing ponds will be filled in during reclamation. The mine water discharge pipe should be cut down and plugged with cement grout or similar material prior to backfilling the pond. Please state the operator's plan to plug the mine water discharge pipe. Response: The standpipe will be cut off at ground level. Neat cement will be poured down the standpipe opening with the intent of filling the opening or overflow. The standpipe will then be buried during the pond backfill process. We will photo document the closure of the standpipe for DRMS records. 3. The reclamation plan states that the two mine shafts have been secured. Please describe, in detail, how the shafts have been secured. Response: There are two points of access into the mine workings adjacent to each other. There is a ladder and a powered man-lift or skip which descend into the upper levels of the mine workings. Both points of access are secured with locked metal grates or closures. In addition,the openings are secured within a steel building with steel doors and tamper proof lock boxes. The locks are enclosed and may only be accessed from the underside of the lock box. The openings are secured with a double closure system, locked steel grates and locked steel building. We understand that under the Inactive Mine Program,the owner of a mine is not required to put permanent closures on mine openings. We believe the combination of locked steel grates and enclosing the openings within a steel locked build exceeds what is typically done by the IM 2
