(f) You have committed to mining in a series of two-acre stages, and limiting total disturbance (for bond amount purposes) to two acres also. Please state your understanding that no additiona] disturbance will exceed the two-acre limit in the plan, without contacting this office for revising the plan. (g) As we discussed during our phone conversation, all mining-related activities must be contained within the 9.5- acre permit azea at all times. This includes stripped brush, topsoiUoverburden piles, pitrun stockpiles, and excavation and hauling equipment being stored or operated. Please state your understanding of this. Reclamation Plan (h) The plan is to always have two acres or less to reclaim, as that is what the bond amount will be based on. It is important, therefore, to keep up with the planned reclamation, as well as not allow the site to become a dumping ground nor weed infested. Thos situations may require the bond to increase. Please state your understanding of these comments. Minin and Reclamation Maw (i) The maps in the application aze those that were originally provided, which were not revised after the permitted azea acreage was reduced to 9.5 acres. The areas indicated on the maps still measure over 10 acres, so the maps should be revised to show the slightly reduced acreage. You stated to me that the onsite access road akeady exists, so the entire 9.5 acres may be included within the gravel pit azea. (Note: The revised boundaries and other features on the new maps should be drawn correctly to scale, and the dimensions of the 9.5-acre permitted azea rectangle should also be given.) (j) When you revise the mining map, please also include these features: lines delineating the two-acre mining stages; an arrow indicating the direction of mining; and the topsoil/overburden stockpile location(s). (Note: Since there aze five stages, it may be helpful to prepaze two miming maps: one depicting the site during stage one, and another depicting a later stage.) Reclamation Cost Estimate The details of your operation have allowed an estimate of the reclamation costs. The attached pages are the various reclamation tasks that this office feels aze needed to reclaim the site at any given time during mining and before reclamation is fmished. The total is estimated to be $6,160. You will note that there are costs for the State administering a contract with an outside company hired to do the reclamation. The costs are usually higher than those that an operator would incur doing the reclamation himself, but please understand that this is customary, since in the case of a default in which an operator cannot finish the reclamation, the State must have a sufficient bond to hire a contractor. (Note: During the life of the permit, the bond may be increased to reflect additional disturbance, or decreased to reflect additional reclamation.) The fast page of the packet lists the direct costs for the tasks plus the induect costs, and the following pages show the detail of those tasks. Here is a bit of explanation of how I calculated those tasks: You stated that the 2:1 slopes would be continually maintained during mining, so I have not included any slope grading task. However, to perform the topsoiUoverburden replacement and spreading, I have utilized a 928 loader to drag some of it down the slopes, and a D7 dozer to spread the rest of it across the pit floor. The assumption was that some topsoiUoverburden will be piled along the edge of the pit above the slopes, and some of it would be piled on the pit floor. The dozer can also be used to rip the compacted areas on the floor. The 2:1 slopes aze too steep to run a seed drill on them, so the seeding was calculated by using an ATV-pulled broadcast seeder, on the slopes and the floor. The surfaces aze then dragged to incorporate the seed for better germination.
