maximum vertical settling predicted at this site was less than 20 inches. The worst possible subsidence consequences <br />anticipated included the potential for wire spans associated with the facility to become unacceptably stressed or <br />broken. This did not occur. <br />Telephone Service <br />Telephone service lines parallel the county road and were not significantly impacted by TCC's mining operation. In <br />the event a line was severed a repair crew could be mobilized to perform the required repairs and reestablish phone <br />service. This was not needed as the mining did not disturb the line. No monitoring was done on the telephone line. <br />Ground Water Hydrology <br />The impacts previously predicted for the Foidel Creek Mine will apply to the Southwest Mining District. Two springs <br />exist in the Southwest Mining District and are monitored to determine impacts. One of the springs saw no impacts, <br />while the lower spring has dried up. <br />EASTERN MINING DISTRICT <br />A review of recent aerial photographs and a limited field inspection were utilized to identify the structures and <br />renewable resources located within the Eastern Mining District. These are shown on Map 2313, Structures and <br />Renewable Resources. The various land uses are shown on Map 3, Land Use. The subsidence impacts for the <br />various structures are presented in Exhibit 7E, Prediction of Subsidence, Eastern Expansion to the Foidel Creek <br />Mine. Please note that the impacts shown for Fish Creek are presented with the understanding that this is <br />informational and will be resubmitted at the time Fish Creek will be undermined and subsided.
