<br />present along some of the property and permit boundaries. These are considered permanent or man-made <br />structures and should be shown on the map. The maintenance of these fences during mining and/or their <br />reconstruction after minine will be discussed further in section 6.4.19. <br />Finally, the type of vegetation covering the affected lands is required to be shown on this map. This <br />information can probably be transferred from the NRCS range site descriptions included under Exhibit J. <br />6.4.4 EXHIBIT D- Mining Plan <br />The mining plan is adequate with the exception of a couple of areas that will require clarification and or <br />additional detail. The primary concern is the topsoil/overburden stripping and replacement plan. It <br />appears that [here is little distinction made between topsoil and overburden with respect [o stripping, <br />stockpiling, and replacement. In fact, the terms seem to be interchanged frequently, however, the soils <br />information provided with [he application seems [o indicate that there is a distinctive boundary between <br />the two with an adequate amount of topsoil available for use during reclamation. Please clarify that the <br />topsoil will be stripped and stockpiled separately from [he overburden and indicate the approximate <br />volume or stripping depth of each material or justify not separating topsoil from the rest of the overburden <br />and clarify those material handling procedures. Also, please identify a quick growing, temporary seed mix <br />that will be used to stabilize any overburden or topsoil stockpiles that will remain in place for more than <br />one year. In addition, as stated under Exhibit L, more detail needs to be provided with respect to the <br />mining sequence within each phase. This is needed for clarity of understanding the mining sequence and <br />to more accurately calculate the financial warranty. <br />6.4.5 EXHIBIT E- Reclamation Plan <br />The reclamation plan is adequate with a couple of exceptions. As discussed in the mining plan, the <br />topsoil removal and replacement is somewhat unclear. Please provide a range of topsoil salvage and <br />replacement depths that reFlects the amount of in-situ topsoil present (IE; 6-] 2 inches). The plan also <br />discusses replacement of 3H:1 V slopes, however, the reclamation plan map does not clearly illustrate <br />where these slopes will be. [t appears that they will be located along the north and south boundaries where <br />the permit adjoins other property. Please clarify the location of the sloped areas. <br />The final item concerns the control of noxious weeds on the site. During the pre-operational inspection, <br />no noxious weeds were observed on the site, however, gravel operations are ideal habitats for the potential <br />establishment and spread of noxious weeds. With this in mind, and in order to comply with Rule <br />3.1.10(6), the application should include a noxious weed management plan which includes a trigger <br />mechanism for implementing control measures based on the observance of any listed noxious weeds. <br />Particular attention should be given to topsoil and overburden stockpiles and freshly reclaimed areas, <br />however, all areas of the mine should be monitored [o avoid transporting weed seeds off site in the event it <br />becomes established anywhere on the mining site. You should be able to contact the local weed control <br />district or cooperative extension service to obtain help in preparing a plan.
