• Page 2 July 23, 2003 <br />10. Peter Wayland M.S. Geologist has signed 6chibit F -Reclamation Plan Map. <br />6.4.7 EXHIBR G -Water Information <br />11. Coulson would like to choose option D) whereas a temporary substitute supply plan and <br />associated well permit will be in place prior to mining below the water table. It is not anticipated <br />that the well permit will be approved prior to the decision date for this application and therefore <br />the applicant would request that the well permit be a wndition of approval. . <br />12. There are no wells within 600ft of the proposed excavation. <br />13. Approximately 2 acre ft of water per year will be used for dust control and washing materials. <br />14. Operational water will come from pumped groundwater-that will be augmented with the <br />temporary substitute supply plan <br />15. Flow meters will be installed upstream and downstream of the pit site to determine historic <br />ditch foss. If pumping affects the ditch flows, water will be pumped back into the ditch. The <br />details of this operation will be included in the temporary substitute supply plan. <br />6.4.12 EXHIBIT L -Reclamation Costs <br />16. The revised plan divides the project into two phases. Phase I will occur east of the gas pipeline <br />and Phase II west of the gas pipeline. <br />17. F~chibit L has been revised to reflect 2ft topsoil replacement <br />18. Dewatering cost in exhibit L accounts for worst case scenario <br />6.4.19 EXHIBIT S -Permanent Man-made Structures <br />19. The permit area has been adjusted to occur greater than 200 ft from the Hillsborough Ditch. An <br />agreement with Kaneb pipeline could not be reached and therefore a revised Geotechniral <br />slope stability analysis has been performed. The results of the analysis show a 40ft setback <br />measured from toe of slope is adequate to protect the pipeline regardless of pit wall slope. <br />20. Additional permanent man-made structures within 200 ft including an old building in severe <br />disrepair and irrigation laterals used only by the Stroh farm are on Coulson property and are <br />owned by Coulson. <br />Additional Comment from Mr. Sorenson <br />Please see response td Exhibit S <br />I hope we have addressed the adequacy review comments completely. <br />Sincerely, <br />I~ "~~ ~l,ti,~~ <br />Peter Wayland <br />President <br />
