Mr. Thomas A. Schriever Division of Minerals & Geology December 6, 1993 Page 2 NO. 3 PERMANENT AND MANMADE STRUCTURES The applicant has shown on Exhibit C, (Pre-mining/Mining Plan) that a 200 foot setback has been provided for all structures on the periphery of mining site. These adjacent structures, such as residences, Atchison Topeka and Santa Fe Railroad tracks, and Southeast Colorado Power transmission lines will not be damaged. The relocation of internal electric distribution lines for well pumps owned by Colorado Power will be at the owner's expense. A permission letter from the SE Colorado Power is forthcoming. Irrigation ditches, wells, and internal farm roads, all owned by the present owners, will be relocated at their expense. Since the farming operation will be a continuous operation along with the mining for this site, all relocated internal electric lines will be in continuous use to maintain irrigation water wells. Therefore, we suggest that plans and costs for relocation of these facilities is not necessary. Please see attached letter to Southeast Power for additional data (Attachment B). NO. 4 SEDIMENT CONTROUSTORMWATER The statement made relative to zero discharge is correct. The attached processing plant site plan shows the dimensions of the water recycle ponds and the location of stormwater discharge and siltation ponds. We are aware the stormwater management plan applied for will be incorporated into the mining and reclamation plans for this site. Note that no anticipated changes are expected for tF~e 112 application by implementing the SWMP plan. See attached SWMP and stormwater Discharge Permit applications to the Colorado Department of Health (Attachment C). N0.5 TOPSOIL V`Je concur with the Division of Minerals and Geology that proposed cropland areas should have a minimum of 18 to 24 inches of topsoil and the owner agrees to this. We also concur that approximately 220 acres will be returned to shoreline and wildlife habitat and 515 acres to cropland as shown on the Reclamation Plan (Exhibit ~. As requested, the owners will agree to use no topsoil for backfill.
