ALBERT FRET AND SONS, INC. WORTHING SUBDIVISION CASE # 55-76-ZP INTRODUCTION This amendment is to Adams County Case Number 55-76-ZP, a Condi- tional Use Permit for mining sand and gravel. This amendment will not change the intended final use as a private lake area. Below we have addressed the compatibility questions in the Zoning Resolution and explained the request. we filed a Technical Revision with the Divi- sion of Minerals and Geology to allow for dewatering and received the approval on November 28, 2000. The information has been incorporated in this amendment. This packet contains information on our proposed minor changes to the operations and reclamation plan. These changes make the county permit consistent with the state permit as it has evolved over the last twenty-two years. Our request is quite simple, and we go into the details later in this document to support our request. First, we need to dewater the lake area to more efficiently operate it. Dewatering will allow us access to the bottom of the lake where we can find out whether addi- tional gravel lies under a shale layer similar to what we have found in other operation along the South Platte River. Second, some shale will be used during the construction E-470 to fill areas of the ROW from SH 85 to the river. Some of the shale will be used to fill the northeast corner of this site so it is at the same grade as Brighton Road. Since dewatering opens the lake of evaluation in may be feasi- ble to construct a water storage reservoir by lining the banks, build a slurry wall around it or a combination of both. If during dewatering we find it is feasible to make a reservoir we will have the necessary engineering work done and begin construction. Please refer to the Mining Plan and Reclamation Plan sections of this submittal for the details on how the project will be developed. Because we will not have an exact idea of how much material is left in the mined area until dewatering is complete we are not able to develop a firm time schedule at this time. Once we have the lake dewatered we can analyze those variables and either continue to mine the new reserves and construct the liner or complete mining, shale removal, grade the slopes into the lake and let the lake refill with water. The dewatering is the most important part of this permit change. We have included the detailed analysis of its impact on surrounding properties, prepared for our Mined Land Reclamation Board permit. The analysis of this finding starts on page 11 under the Water heading. The following list contains the necessary permits, permit numbers, their status and comments to dewater the mine. D.M.G.
