OURAY SILVER MINES <br /> b. For each set of QA/QC items please provide a success criterion of each test or <br /> certification to be submitted. <br /> Criteria for success for each QA/QC test is given in 100-SS. <br /> 23. In addition to items 22 a and b of this review, please further define each phase of <br /> construction of the reagent building, and which phases are proposed to have QA/QC <br /> certification or inspections pursuant to Rule 7.3.1(1). <br /> Tasks associated with construction phases and hold points for QA/QC are better defined in Table 7. OSMI <br /> believes that it would be best for the Division to determine which phases of the construction they would <br /> like to inspect. <br /> 24. In addition to item 18 c of this review, please describe stormwater design features <br /> surrounding the Reagent Room Pursuant to Rule 7.3.1(3). What new features were <br /> installed for this building to handle water coming from above the building? <br /> No new stormwater control is needed at the Reagent Room.All upslope water from off the site is being <br /> controlled by Stormwater Ditch#1 as shown on the Environmental Protection Map. The back wall of the <br /> reagent room was designed as a reinforced concrete retaining wall capable of resisting both lateral snow <br /> and earth movement and is sufficient to resist any minor flows off the hillside below the diversion ditch. <br /> 25. Once the phases of construction are defined, including the identification of phases that <br /> require QA/QC certification and or inspection, please commit to providing certification <br /> documentation, receiving any required inspection AND receiving acceptance from the <br /> Division prior to proceeding to the next phase of construction pursuant to Rule 7.3.3(2). <br /> The mine will send QA/QC documentation to the DRMS monthly until certification of the EPF is complete. <br /> The mine will receive any required inspection and receive acceptance from the Division prior to <br /> proceeding to the next phase. Several inspections are required to be completed by the DRMS per rule <br /> 7.4.2(2): <br /> (a) Foundation inspection -corresponds to Lines 4 & 7 of Table 7. <br /> (b) Earthen construction inspection-corresponds to line 3 of Table 7. <br /> (c) Seep inspection—NA, no seeps discovered. <br /> (d) Structural instability—corresponds to line 17 of Table 7. <br /> (e) Under-drains inspection—NA, no underdroins will be installed. <br /> (f) Liner installation—NA, no liner will be installed. <br /> (g) Leak detection—NA, no lead detection system to be installed. <br /> (h) Protective armor—NA, no protective armor is to be installed. <br /> 26. Page 6 of the revision asserts that if DRMS is not able to make an inspection,the Operator <br /> can contract an independent reviewer. If the Operator chooses to utilize independent <br /> review,a request must be made,in writing that clearly addresses all requirements of Rule <br /> 9 1 P a g e <br />
