' EXHIBIT C, Section (b): You have stated that there is no substantial amount of suil suitable for support of plants available at the site but the NRCS Report supplied with the application estimates 3 inches of "fair" topsoil is al least available For the Ryan Park unit ~n ~ Please indicate your awareness of the availability of this topsoil and your commitment to salvaee ~.,,~,I~~k'~ ,~,.tt"~~~ and stockpile such topsoil where possible. If the salvaged topsoil is not to be utilized in reclamation within ~/v "~~Sr one growing season, please also commit to stabilize the stockpiled material and describe how that r~tt'~ V stabilization will be managed. EXHIBIT C. Section (c): You have stated that there is no waste rock at the site but have not indicated if there is overburden. Your minine plan map, however, indicates an overburden stockpile and Exhibit D, Section (I) (a) states that [here is some overburden at the site. ~Y Please estimate [he amount of overburden to be removed during the operation as separate from topsoil. (This estimate should have some relationship to the thickness range of distributed overburden requested for Exhibit D, Section (I) (a) below.) EXHIBIT C, Section (i) and Section (I): You have indicated that storm water runoff from the permit area will be directed toward the highway culvert west of the pit. You have not indicated how the x0~" effect of the disturbance associated with operation on the quality of that runofFand therefore on the quality .,A"~ of surface water in the area will be minimized. In other words, you have not described what will be done to NN minimize the amount of sediment carried off site by that runoff. Please indicate by what means you intend to minimize the effects of the operation on the quality of surface water in [he area resulting from sediment laden storm water leaving [he site. EXHIBIT C, Section (k): You have stated that no refuse or acid or toxic producing materials will be exposed during your mining operation. Sectior, (k), however, requires you to indicate how you will handle such materials if you expose them not whether or not you expect to expose [hem. The Division is 0~ particularly concerned in this regard because your mining and reclamation plan maps indicate an old landfill is present within your permit area. Please indicate how refuse or acid or toxic producing materials will be handled and disposed of if exposed during the mining operation. EXHIBIT D, Section (I) (a): You have stated that less than 12 inches of overburden will be replaced at the exvaction areas upon termination of excavation but no minimum amount of material is O~ estimated. Please estimate the range of overburden thickness that will be replaced. EXHIBIT D, Section (c) (i): Although you stated earlier that there is no topsoil to be salvaged at the site, the NRCS report indicates there is some. (See discussion under Exhibit C, Section (b) above.) You have now stated in this Exhibit that in the event there is insufficient depth of topsoil available, some will be brought in and distributed. You have not specified what constitutes an insufficient depth of topsoil and, in Q~ such case, how much will be brought in for use in reclamation. Please indicate what depth of topsoil is to be considered insufficient for reclamation purposes and, in such case, what thickness of topsoil will be imported and distributed EXHIBIT D, Section (c) (iv): You have stated that seed may be broadcast as well as planted by Qy drill. You have not indicated if a different rate of seeding will be employed for the areas where the seed is to be broadcast rather than drilled in. ~/ Please commit to double the seedine rate for the areas to be broadcast seeded. ~7
