Mr. Bob Siegrist - 2 - November 25, 1985 <br />man-made structures or show us a written agreement with each of the <br />owners of these structures that any potential damage to the structure <br />as a result of your mining activities will be compensated for by your <br />company. The permit ammendment application cannot be approved by the <br />Board unless and until this is accomplished. <br />2. Please clarify your plans for stockpiling non-topsoil overburden that <br />is not immediately used in reclamation. It should be made clear where <br />you plan to stockpile this material. It should also be clear that you <br />plan to stockpile it separately from topsoil stockpiles and plant it <br />for stabilization purposes (as you plan to do with stockpiled topsoil). <br />Exhibit E <br />1. I am concerned with the proximity of the planned lakes to <br />U.S. Highway 85. Some settling of the lake shore areas could occur, <br />~~l t' and a mere 10' buffer between the sloping area of the lake (planned at <br />2H:1V immediately adjacent to the highway) and the highway may not give <br />SQC ~'"~7' adequate long-term stability protection to that highway. Please <br />Q~M,;SS~~"' discuss this issue and consider increasing the distance between the <br />P planned lake shore and the highway. I am sure that this will also be a <br />concern of the Colorado Division of Highways when you discuss the <br />stability of the highway in order to respond to my question 1 under <br />Exhibits C and D, above. <br />2. Please justify your reasons for leaving the two-acre sand bar area <br />between the lakes. If this area is to provide swimming access to the <br />lakes once development occurs, the slopes of the lake in this area must <br />X be no steeper than 5H:1V (". throughout the area proposed for <br />swimming, ..." as per Rule 6.1(f)). Please clarify your justification <br />for your plans for this sand bar and your sloping of any planned <br />cur uyo~s? swimming area. In this regard, given development of the lake shore for <br />biy~v u" -') housing, will not other areas also be developed for swimming? <br />3. I note that an average of 9" of topsoil is planned to be used in <br />reclamation. This depth utilizes only about one-half of the available <br />topsoil, with the balance to be sold. Please justify why only 9" of <br />topsoil is adequate for reclamation when as much as 18" is available. <br />In anycase, no topsoil should be sold unless enough has already been <br />stockpiled to accomplish the reclamation of all disturbed areas with <br />the agreed-upon depth of topsoil, whatever that depth turns out to be. <br />Please respond to this entire issue. <br />Exhibit G <br />1. Please clarify your plans for the disposal of waste water from the <br />gravel washing operation. Presumably this water will always go into <br />an area of one of the two lakes that has not yet undergone final <br />reclamation (even when the gravel in an area is still being mined <br />dry). Please clarify your plans in this regard. <br />X 2. Please clarify the depth to the lake surface in final reclamation. <br />
