Lupton, Co. 80621 (main) 303-857-1754 (fax) 303-857-2933 May 22, 2007 Eric Wilkinson, General Manager Northern Colorado Water Conservancy District 220 Water Avenue Berthoud, CO 80513 Dear Eric, John and I would like to thank you for meeting with us Tuesday May 15, 2007. We appreciate the opportunity of sharing Northern Colorado Constructors, Inc. plans for their gravel mining operation and discussing what impact this may have on the South Platte Supply Canal (Sandhill Canal) that is on the south edge of the mining operation. IAs per our discussion, I am enclosing several documents for your review: 1.) Overall mining plan map 2.) Ground water and wells study for NCC Pit No. 1 3.) Monitoring recordings since Jan. 31, 2007 4.) Slope stability analyses (JACesare &Associates) 5.) Recent photographs of standing water in the canal (2) 6.) Drawing elevation of canal, recharge ditch and mining operation 7.) Slope Stability report (J&T Consulting) 8.) Soils Report from Terracon We are currently mining in phase 5 at the pit. We will finish this phase in approximately 3 months. At that time, we would be ready to start the installation of the clay liner along that part of the south pit boundry. Phase 11, which is directly east of phase 5, is not scheduled to be mined for approximately 3 years. The Ground Water and Wells report and accompanying cone of depression titE;Ian{ r c i91 s` ' r t - f s ".reuln+ . .}. ,r„• bl a. 1 :1 Cidnp r,ij 3 gn,iicantly to [tic next tew day-, , .'ir[ eet to begirt flowing • 1000 gpm into the recharge ditch. It is our expectation that the water table will come up from where it currently is and maintain the level during our mining of the gravel to within the 70 feet offset from the top of North Ditch Bank. Also enclosed you will find a drawing of the elevation at the bottom of the Sandhill canal and the elevation at the bottom of the recharge ditch. The drawing also shows the current elevations of the water table in monitoring well No. 4 and the distance from the top of the north bank of the canal to the center of the recharge ditch and the distance to the edge of our mining limits. There are two recent photographs enclosed. The first one taken May 11, 2007 and the second one taken May 21, 2007. They were from the same place and indicate that the water level currently in the ditch has changed very little in the past 10 days. We would ask that you consider the information presented and propose that NCC furnish you with our well monitoring reports from No. 3 and No. 4 monitoring wells. If the ground water remains at or higher than presently exists, it would suggest that no water is seeping from the Sandhill Canal. After the mining is complete in phase 5, NCC will install the clay liner for the permanent remedy. When mining begins in Phase 11, NCC would follow the same procedure and with the installation of the clay liner across the south end of phase 11, the entire south end of the gravel pit would be sealed. If there are any questions, please call me at (303) 857-1857. We look forward to hearing from you on this matter.
