6 <br /> approved the operator' s conditional use permit. Mr. Munzert <br /> said four letters of objection were received on November 23 , <br /> 1993 , but were withdrawn after the company held further <br /> discussions with the objectors. <br /> Mr. Munzert stated that, prior to mining, topsoil and <br /> vegetation would be removed from areas of disturbance and that <br /> usable topsoil would be stockpiled, and sediment controls <br /> would be constructed where necessary to prevent erosion of <br /> disturbed areas. He said that a haul road overpass would be <br /> constructed over Highway 67; diversion ditches would be <br /> constructed to divert all precipitation away from the pit and <br /> that the leach pad would be designed for a 100-year, 24-hour <br /> runoff event. Mr. Munzert discuss the propsed operation in <br /> detail. <br /> Mr. Munzert stated that after the completion of mining a drop <br /> bench would be excavated around the perimeter of the pit, <br /> access would be provided for wildlife, and the perimeter would <br /> be fenced. He said that the waste dump outslope would be <br /> graded to specifications and that the top of the waste dump <br /> would be scarified, topsoiled and seeded and that bushes and <br /> trees would be planted in some areas. Mr. Munzert stated that <br /> the leach pad would be rinsed until the effluent water meets <br /> water quality standards and then the slopes would be graded to <br /> proper specifications, topsoiled and seeded. He said that all <br /> buildings would be demolished. <br /> Mr. Hardaway stated that the operator was in the process of <br /> negotiating a resolution of the issue involving land access <br /> with American Rare Minerals (ARM) . <br /> Mr. Hardaway said the operator performed test blasting in the <br /> area, in order to determine an equation for the protection of <br /> sensitive structures and to answer the questions posed by the <br /> OSM representative. Mr. Hardaway stated that they did not <br /> detect surface vibrations during the tests. He said that the <br /> operator would conduct blast monitoring around the facility, <br /> and that permanent test stations would be placed in the Town <br /> of Victor. <br /> Mr. Hardaway said that during their experience with another <br /> operation where open cut and underground mining were conducted <br /> simultaneously, no underground workings were affected by <br /> blasting. He stated that their operation would not produce <br /> flooding of underground workings, due to blasting. Mr. <br /> Hardaway stated that the Carlton Tunnel is the lowest and main <br /> drainage tunnel on the site and that its average flow has not <br /> changed other than annual, seasonal fluctuations. He said <br /> they had also inspected the Moffat Tunnel and found it to be <br /> dry on one occasion. <br />
