• either the mine or loadout areas and physical separation between <br />Southfield's ongoing mining operations and the Trinidad Sandstone by <br />approximately 300 to 400 feet of relatively impermeable siltstones and <br />shales effective precludes any potential mining related impacts on this <br />unit. Mining and related activities are expected to result in some <br />localized impacts on groundwater flows and levels. However, EFCI's <br />operations will not result in disturbance or direct impacts to any <br />groundwater recharge areas. Groundwater recharge mechanisms in the mine <br />and loadout areas are not well understood. However, it is believed that <br />recharge occurs in outcrop areas to the east of the mine area or along the <br />Wet Mountain fault and at the margins of adjacent upturned sedimentary <br />units. Since no direct impacts on recharge areas will occur and impacts <br />on recharge mechanisms will be localized and temporary as described in <br />Section 2.05.6, Mitigation of Surface Coal Mining Operation Impacts, no <br />specific measures are necessary to protect or restore groundwater recharge <br />capacity. <br />• 4.05.13 SURFACE AND GROUNDWATER MONITORING <br />The groundwater monitoring program described in Section 2.05.6, Mitigation <br />of Surface Coal Mining Operation Impacts, provides relevant information <br />on groundwater levels, recharge and discharge rates and water quality. <br />The monitoring plan insures a frequency and distribution of groundwater <br />data collection adequate to identify and document trends and fluctuations <br />in the quantity and quality of groundwater and the overall effects of <br />mining on the hydrologic balance. The groundwater monitoring data and <br />resulting evaluations will be used to identify any potential problems on <br />a timely basis and develop any necessary mitigation measures. <br />The proposed surface water monitoring plan together with the monitoring <br />required for NPDES permits is described in Section 2.05.b, Mitigation of <br />Surface Coal Mining Operation Impacts. This plan provides for measurement <br />and recording of the quantity and quality of all discharges from the <br />permit area. The frequency, density and accuracy of monitoring will allow <br /> <br />4.05-25 <br />
