2.05 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND ACTIVITIES -- <br />MINIMUM REQUIREMENTS FOR OPERATION AND RECLAMATION PLANS. <br />2.05.6 Mitigation of Surface Coal Mining Operation Impacts. (Cont'd.) <br />(3) (b) (ii) (Cont'd.) <br />The operator believes that periodic reevaluation of the groundwater monitoring program is <br />necessary and will report to the Division monitoring results and projected changes to the monitoring <br />program in the "Annual Hydrology, Subsidence, and Mine Inflow Report". The "Annual Hydrology, <br />Subsidence, and Mine Inflow Report" will be submitted to the Division by April 30 of each year. <br />Groundwater monitoring specified in Tables 3 and 4B of Volume 4 will continue until cessation of <br />operations and /or approval of the Division. <br />Post Reclamation Monitoring <br />When regrading and backfilling of the east mine site is complete, nine piezometers will be installed <br />in the backfilled wedges to monitor groundwater saturation. The piezometers will be installed where <br />shown on Map 6A -5D. One piezometer will be located in the fill wedge above the crushing and <br />screening level. Two piezometers will be located in the fill wedge above the shop level. One <br />piezometer will be located in the fill wedge above the parking level and two piezometers will be <br />located in the fill wedge above the office level. Three piezometers will be located in the fill wedge <br />above the fan level. The piezometers will be installed throughout the entire thickness of the fill <br />wedges. The piezometers will be monitored quarterly through the first two years following <br />backfilling and annually in June thereafter for the duration of the reclamation liability period or until <br />cessation of monitoring is approved by the Division. If unacceptable saturation occurs within any of <br />the fill wedges, remedial measures would be developed and implemented by the operator. A typical <br />piezometer well completion diagram is presented in Volume 6A, the Phase II Study, Geo -Hyro <br />Consulting, Plate 6. <br />PR -04 -124- 06/10 <br />Ffrzoveb <br />//13// / <br />
