6.4.21(15)Construction Schedule Information <br /> No less than 30 days prior to commencement of GMR milling,the FTSF and ancillary structures will be <br /> constructed. The structures ancillary to the FTSF include the stormwater diversion channel that diverts <br /> stormwater from running into the FTSF area, FTSF monitoring wells and the contact water pond. <br /> 6.4.21(16)Quality Assurance and Quality Control(QAQC) <br /> Mill development will be supervised by licensed engineers and contractors. A licensed professional <br /> engineer who specializes in mine facility development will be on site during construction and will <br /> conduct inspections. Mill and mine development will occur with engineering oversight that will ensure <br /> the mine and facility, including the mill, are constructed in accordance with approved designs and <br /> specifications. The engineer will prepare a certified report for the installation of the contact water <br /> pond, FTSF underdrain, stormwater detention pond, mill and diversion ditches. <br /> 6.4.21(17) Plant Growth Medium <br /> Suitable plant growth medium is present within the proposed affected area. Plant growth medium will <br /> be salvaged from the mill facility and the footprint of the FTSF prior to installation of the underdrain. <br /> Because the mill site is located at the toe of a mountain range, ample plant growth medium is present in <br /> the canyons and ravines. Information regarding plant growth medium to be used is in Exhibit I: Soils <br /> Information. <br /> 6.4.21(18)Wildlife Protection <br /> Colorado Natural Heritage Program and Colorado Parks and Wildlife provided wildlife information and <br /> harm prevention guidance. The reports are provided in Exhibit H and Appendix G. <br /> The mill site is primarily native undisturbed wildlife habitat that may be frequented by hikers and off <br /> road vehicle enthusiasts albeit as trespassers since the proposed affected area is privately owned <br /> property. Other than historic mountain trails and internal dirt roads,the proposed mill site is <br /> undisturbed. <br /> Public lands owned by BLM, USFS and SLB surround the proposed permit area with the exception of a <br /> portion of the east and northeast boundary. The area is known for mule deer and bighorn sheep to the <br /> north and northwest. Whereas raptor nesting and other transitory wildlife might be present, raptor <br /> nesting sites are not present in the Project area. The area was surveyed by Raquel Wertsbaugh, CPW <br /> representative,for Townsend big-eared bats in January 2013. No bats were encountered and the <br /> attractive abandoned adits will be permanently sealed to prevent habitation. <br /> The CNHP identified the Grape Creek Water Gap as a high biodiversity area. This area is more than two <br /> miles west of the proposed affected area boundary. The Bott's Pocket gopher was identified as the only <br /> rare and/or imperiled mammal in the vicinity. It was observed in Township 18 South, Range 70 West, <br /> beyond the boundary of the proposed mine. <br /> Wildlife protection measures will begin with an affected area boundary wildlife fence. The contact <br /> water pond is located in what will be a very active area of the surface facility. In addition to the <br /> perimeter fence, 24 hour/7 days a week site activity will discourage mule deer from being present on <br /> the site. As mentioned above in Section 6.4.21(14), based on geochemistry analysis of tailings, the <br /> 78 <br />
