Materials and spare pipe used to repair the lines are stored at the <br />treatment facility as well as at various locations along the service road to insure <br />prompt repair. The storage capacity of the Palisade facility is 5 million gallons. <br />Considering that Ute Water can service approximately 45,000 water users for <br />18 to 20 hours on 6 million gallons reserve, the Town of Palisade can supply <br />the less than 5,000 Palisade water users for a much longer time period than is <br />required to repair the water supply line and bring the treatment facility back into <br />service. Based on this information, material damage or diminution of <br />foreseeable use of the Palisade pipelines will not occur. <br />Worst case predictions for subsidence affects on the~3451<V~Colorado•Ute= <br />transmission line are given inRAppendix~20=5: Current projections for mining in <br />the area of this line involve mining 70 ft.

The depth of cover will <br />range from 1500 ft. to 2300 ft. and the mining height will range from 5 to 7 <br />feet. The worst case scenario for room and pillar mining in tables 3 and 5 of <br />this appendix assumes 76% extraction, 1200 to 2400 ft. of cover and an 8 ft. <br />mining height. In this worst case at 1500 ft., vertical subsidence would be 1.07 <br />ft., tilt would be 20.8 minutes or 0.71 ft. fora 117 ft. tower and the maximum <br />diagonal displacement of the base would be 0.14 feet.
