Applegate <br />roue, Ina. <br />July 3, 2008 <br />Mr. Gary DeWitt <br />Colorado Department of Transportation <br />Region Four Materials <br />3971 W. Service Road <br />Evans, CO 80645 <br />CEIVE® <br />JUL 18 2008 <br />Division of Reclamation, <br />Mining and Safety <br />RE: Connell Resources, Inc. Mining Permit Application for SerFer Pit <br />Dear Mr. DeWitt: <br />We are in receipt of your letter dated April 9, 2008 regarding Connell Resources, Inc. Mining <br />Permit Application for SerFer Pit (M-2008-006). In addition to the letter dated April 9, 2008, <br />representatives met with you and Joe A. Intermill, Jr. at the proposed mining site on May 7, <br />2008 to discuss site specific concerns from CDOT. Below are our responses to comments. <br />® It states on page six of the application that de-watering trenches will be excavated <br />around the entire perimeter of the disturbed area. Is this the entire 45+ acre site, <br />the 30 acre mining site, or the no more than 15 acres that will be disturbed for <br />mining at anyone time? Page 11 says the trenches will be constructed around <br />--half of the perimeter of-the-pit- Could-we have a clarification- on-this-natter?- - <br />According to the mining plan, no more than 15 acres will be exposed at <br />any one time. The dewatering trenches will only be required for active <br />mining within the exposed area. Furthermore, reclamation will be <br />performed concurrently with mining resulting in the removal of the idle <br />trench sections in order to install the clay liner. <br />We assume these trenches be located in the area to be mined and not in the set <br />back areas between the mined area and affected area boundaries. <br />The trenches will be located within the boundaries of the approved mining <br />permit and in the vicinity of active mining. <br />0 What will be the back slope of these trenches? Steep back slopes left for an <br />extended period of time could cause caving back into the set back areas and <br />reduce their width. <br />1499 West 120th Avenue,.
