referenced in this section are P-3 and P-5, which were energy dissipator <br />ponds that entrained runoff from a steep slope. Both the slope and the ponds <br />were located above the mine operation area. Therefore, they prevented clean <br />water surface flow from reaching the reclaimed area. The two ponds have <br />been reclaimed. <br />D. Surface and Ground Water Monitoring <br />1. The applicant will conduct monitoring of ground water in a manner approved <br />by the Division. The ground water monitoring plan is as follows <br />(4.05.13(1)): <br />Monitoring wells D-lA and D-2A at the base of the refuse area are to be <br />monitored for water level, pH, electrical conductivity, and temperature. The <br />sampling frequency for the ground water monitoring wells is quarterly. <br />The No. 1 and No. 3 mine discharges, NPDES discharge points 001 and 007, <br />respectively, will also be monitored. According to the NPDES permit, <br />discharge point 001 will be monitored weekly for flow rate, pH, and oil and <br />grease, monthly for TSS and total recoverable iron, and quarterly for TDS. <br />Discharge point 007 will be monitored monthly for flow rate, pH, oil and <br />grease, TSS and total recoverable iron, and quarterly for TDS. <br />2. The applicant will conduct monitoring of surface water in a manner approved <br />by the Division. The monitoring plan was submitted under 2.05.6(3)(b)(iv) <br />and includes the following (4.05.13(2)): <br />Two sites, one upstream and one downstream of the mine area, will be <br />sampled for TDS, pH, Ca, Fe, Mn, SO,, TSS, HCO3, Cl, Mg, Na and Zn. <br />The sampling frequency for surface water is biannual. <br />E. Stream Buffer Zones <br />1. The Division approved surface or underground mining activities within 100 <br />feet or through a perennial stream or stream with a biological community. <br />This decision is based on a finding that the original stream channel will be <br />restored, water quality and quantity shall not be adversely affected, and <br />appropriate riparian vegetation will be reestablished. The buffer zone <br />variance is granted for the area where the pre-law adit between portals No. 1 <br />and 2 undermines North Thompson Creek (4.05.18(1)). <br />F. Probable Hydrologic Consequences of North Thompson Creek Mine <br />1. Ground Water <br />is <br />
