To date, there have ~,vi~W <br />been no significant discrepancies in monitoring results and the <br />MLRD has not expressed any previous concerns.. With due <br />consideration of the concerns expressed relative to the <br />hydrologic monitoring program, Kerr has reviewed monitoring <br />locations and is recommending specific plan revisions to address <br />these concerns. <br />The current monitoring program, which was approved as a revision <br />to the original permit in 1984, reflects a phased approach, with <br />expansion of the monitoring network keyed to progressive mining <br />advance. <br />Current Phase I monitoring activities include all existing wells <br />south of the county road. Kerr proposes that the Phase I <br />program be modified to include only those monitoring wells on <br />the west limb of the Johnny Moore syncline in the immediate area <br />~ of existing Pit 1 and 720 Pit disturbance areas. <br />There are several wells on the eastern limb of the syncline <br />which have been monitored throughout the period of active mining <br />operations. During this extended period, there has been no <br />evidence of any mining related impacts for any of these wells. <br />Therefore, Kerr proposes that the fallowing wells be eliminated <br />Ifrom the monitoring program: <br />~~( ~ DH-6 79-27 79-36 AI-2 <br />{~ _ 79-26 79-32 AI-1 <br />Table 62, Kerr Mine Area Monitor Well Inventory, and the Mine <br />Area Surface Water Hydrology Map, (Map 16a), have been revised <br />to reflect the change and are included with this response <br />submittal for replacement in the original permit document. <br />I For remaining wells included in the current Phase I and proposed <br />Phase II monitoring programs, Kerr recommends a joint MLRD/Kerr <br />inspection during the spring or summer of 1990 to assess the <br />11 <br />
