Letter to Jay Jones -3- November 29 1995 <br /> event of a spill. <br /> 7. In section 4. 1. 1.2 of the EPP application, it is stated that lime <br /> and sulfuric acid used in the water treatment process would be <br /> removed from the site as soon as they were no longer required in the <br /> water treatment process, it is likely, however, that perpetual water <br /> treatment in some form will be required. This likelihood is <br /> recognized in section 8 of the original Climax Mine Reclamation <br /> Permit application. In section 10.21 (section 10 is the reclamation <br /> plan section) of the original permit application, it is stated that <br /> all buildings, facilities, etc. , will be dismantled. It is further <br /> stated that mine shafts will be plugged according to post-mining <br /> water control needs. Continuing treatment and discharge of mine <br /> water, tailing seep water, waste dump seep water, etc. will result <br /> in the need to maintain numerous surface facilities that would not <br /> necessarily be in accord with the approved post-mining land uses. <br /> Please describe and illustrate the surface facilities that will <br /> remain at the mine site in order to continue treatment and discharge <br /> of contaminated water once the site is reclaimed, including <br /> information on long-term sludge handling and disposal. <br /> 8. In general, the Materials Containment Plan and Spill Prevention, <br /> Containment and Countermeasure Plan submitted as Appendix B of the <br /> EPP application meets the minimum requirements for an Emergency <br /> Response Plan specified in Rule 8. 3.2 of the Mineral Rules and <br /> Regulations. Please designate two key response individuals that can <br /> be contacted on a 24-hour basis. Also, please list the contents of <br /> the spill kits discussed in the EPP. <br /> 9. Additional information is needed to satisfy the requirements of Rule <br /> 6.5 - Geotechnical Stability Exhibit - of the Mineral Rules and <br /> Regulations, including: <br /> (a) Provide a demonstration of slope stability for the reclaimed <br /> configurations of the waste rock dumps approved in the Reclamation <br /> Permit, including an assessment of the factor of safety against <br /> failure. This assessment must consider the potential affects of <br /> pore pressures within the dumps on bulk stability. <br /> (b) In the current Reclamation Permit, open pit slope <br /> configurations are approved to be approximately 1:1 overall, with <br /> near vertical bench angles, in portions of the pit developed in more <br /> competent rock east of the Mosquito Fault, and angle of repose <br /> slopes (approximately 1.5: 1) are approved for portions of the pit <br /> that are developed in Paleozoic, sedimentary rock west of the <br /> Mosquito Fault, or where subsidence and sloughing has occurred. <br /> Since pit bench deterioration and sloughing are an accepted <br /> component of the approved reclamation plan, the Division is only <br /> concerned with the deep-seated or bulk stability of the pit walls. <br /> Please provide a discussion of the bulk stability of the pit slopes <br />
