There are no streams, takes, reservoirs, or ponds that <br />would receive drainage directly from the proposed affected area. Water and sanitary facilities <br />complying with Boulder County Health Department Regulations wiII be provided for employees, but <br />installation of water or sewer lines will not be required. <br />Dicing the course of query operations and after the operations are concluded the effect on flora and <br />fauna will be mitigated through best management practices which are detailed in the mining plan, <br />Exhibit C, and the reclamation plan, Exhibit D, and discussed below. There are no signi&canT <br />historic or archeologic resowces that will be impacted by the quarry operation. There aze also no <br />identified critical wildlife habitats in of neaz the quarry site. There is no potential radiation hazard <br />on the site- <br />Reclamation Pian <br />The reclamation plan is detailed in the attached Exhibit D, which includes the Applicant's specific <br />responses to the Colorado Stare § l 10 Permit requirements. The proposed grading has been designed <br />in a manner to minimize the impact to the environment. Replacing overburden will be conducted on <br />an ongoing basis, where practicable, as part ofnonnal quarry operations. Estimated depths wilt vary <br />between lft and 20 ft. The stops of the proposed site currently ranges from 5% to 55% (Non- <br />Technical Soil Description, Exhibit B). Gradient used for reclaimed slopes will be 3:1 were the <br />original slopes support it. Crradients of greater than 3:1 will be used only in azeas where the original <br />slopes are in excess of 3:1, never to exceed the original slope maximum gradient of 55%. The intent <br />is to return the slopes to their approximate original gradient, and leave rock benches where they may <br />land Use & Dnrtopmmt Plonmag- Barmefs Fomratioa & Eenp(ayer Defense- Government ~ Pabkc Rdakwu <br />Phorre: 303.447.2555 4 FA.Y.~ 303.447.2635 O Cell Phoxe: 303.93!.5089 4 8=marl: adbyrneQsmartlanduse.cnm <br />
