PVRE Pit#1 <br /> 10)Has"Jack's Lane"been constructed?If so, please provide a description of this road and a picture of this road <br /> and indicate if the road wil I be improved to support the mining operation. Based on the definition of"Affected <br /> Land" in Rule 1.1(3),roads must be included as affected land unless the road existed prior to the date on which a <br /> permit application was made to the Office and which was constructed for purposes unrelated to the proposed mining <br /> operation and which will not be substantially upgraded to support the mining operation. Also, per Rule 6.3.3(g), new <br /> or improved roads must be included as part of the permitted acreage. If the road does not exist, it must be <br /> included in permit acreage, and given that the proposed permit area is already 9.9 acres including this road would <br /> require the applicant to withdraw this 110 Limited Impact Operation application and submit a 112 application or <br /> reduce the proposed permit area below the 10 acre Limited Impact Operation threshold. <br /> Jack's Lane is a new road which will service Platte Valley Industrial Park,a new subdivision which is <br /> currently being proposed by Platte Valley Real Estate LLC and is under review by Logan County. We would <br /> argue that the primary function of this roadway is to serve the new industrial lots being created in the Platte <br /> Valley Industrial Park subdivision. It will be in place and serve that function for many years above and <br /> beyond the life of this pit.A copy of the subdivision plat is attached. The gravel pit operation will simply be <br /> using a roadway built for the industrial property owners. The subdivision roadway has not been included in <br /> the 9.9 acres at this time. <br /> Exhibit 6.3.4, Exhibit D—Reclamation Plan <br /> 11)Per Rule 6.3.4(1)(a),please specify at what point in the mining plan the overburden and topsoil will be replaced <br /> in relation to ongoing extraction. <br /> Our assumption is that the final pit will fill with water. When mining reaches the outside edges of the four <br /> sides,topsoil and overburden will be replaced around the outer fringes of the pit. <br /> 12) Similar to item No. 6 above, please revise the topsoil replacement depth based on the revised soils information <br /> discussed in item No. 4 above. <br /> The topsoil depths on the corrected soil types could extend up to 14-17 inches. We are committed to replace <br /> an equal depth around the perimeter of the pit in all areas not under water during reclamation. <br /> 13)Please revise the reclamation plan to indicate that the pit slopes will be graded to a 3:1 horizontal to vertical <br /> ratio at least five feet above to ten feet below the water line if water will fill the pit excavation and that all other <br /> slopes will be no greater than a 2:1 slope per Rule 3.1.5(7)and Rule 6.3.4(1)(d). <br /> The revised reclamation plan should reflect that the pit slopes will be graded to a 311:1V slope at least five <br /> feet above to ten feet below the water line if water fills the excavation. All other slopes will be no greater than <br /> a 2:1 slopes. <br /> 14)Please indicate at what point in the mining plan when the site will be seeded per Rule 6.3.4(1)(c)(ii). <br /> Seeding will occur on each of the four sides following replacement of overburden and topsoil and preparation <br /> of the soil. This will occur after mining has ceased from that side of the pit. <br /> 3 <br />
