-11- <br />• an emergency response plan to ensure that the drainage or whatever is <br />protected. Where you're going is that it does overlap or meet up against some <br />other agencies which also have some requirements for emergency response. What <br />we have done is -- you know we are restricted with respect to any solution <br />that may escape the site and what is necessary to neutralize that solution but <br />the companies, typically, since they have a response on their other programs, <br />have come forth with a more comprehensive plan. So that's what's happened on <br />that. <br />MR. RENNER: Regarding the buttress, the buttress along the south wall of <br />the West Pit, we added a proposal during the last Board meeting to install <br />this buttress if it is necessary to~maintain the long term integrity of the <br />south wall after mining operations are completed. At the time of the Board <br />meeting we had not had a' chance to evaluate the technical aspects of the <br />buttress. We since have had the chance to do so. We have forwarded to the <br />Company some concerns and comments which we have had and received replies to <br />• those. <br />Essentially, the buttress is a waste rock dump adjacent to the south wall <br />and, actually leaning up against the south wall. It's function its to hold the <br />wall in place after mining. It's approximately 900 feet in length and will, <br />as I said, ensure the long term stability of this structure. It will extend <br />from the pit bottom to about the area of the Santa Fe conglomerate and <br />alluvial material contact. It will be about 140 feet tall and wiill be divided <br />into two slopes. The upper slope will be about 60 feet tall and will be <br />about38 degrees overall slope. There will be some intervening flat areas and <br />benches created during the construction of this facility. <br />The lower 80 feet would be constructed to a 3 to 1, or 18 degrees slope. <br />This lower portion will be topsoiled with eighteen inches and revegetated <br />according to the reclamation plan we have in hand. The upper slope would also <br />be broadcast seeded and would be randomly planted with pinon juniper type <br />vegetation. The idea being to create a talus slope type environment in this <br />area. <br /> <br />
