mining operations may be dewatering an overlying perched aquifer, which <br />are relatively common within the Menefee Forntation. It is possible, <br />however, that some inflow from the Pine Gulch drainage may be occurring. <br />Continued observation and monitoring will help to determine the source of <br />this inflow. <br />To date, the amount of water being discharged to the west pond has been <br />minimal. If, however, mine dewatering causes either of the two sediment <br />ponds to discharge, National King Coal has committed to monitoring the <br />parameters listed in Table 2 within 24 hours after pond discharge at the <br />alluvium well in Hay Gulch. Thee results will he submitted to the Division <br />with the Regular quarterly monitoring submittal (4.05.1(2)). <br />Table 2 <br />Depth to Water (Ft.)

The applicant will conduct monitoring of surface water in a manner <br />approved by the Division. The monitoring plan was submitted under <br />2.05.6(3)(b)(iv) and includes the following: (4.05.13(2)). <br />Surface Water Hydrology -Rule 4.05 <br />Information on surface water hydrology can be found in Sections 2.04.7, <br />2.05.3 and 2.05.6 and Maps C-4 and C-9 of the permit application. <br />The surface Facilities of the King Coal Mine are located in a small <br />ephemeral drainage basin which is tributary to Hay.Gulch. The pernrit area <br />and underground mining extending to the south of the surface facilities and <br />underlay another small ephemeral drainage basin which is tributary to Pine <br />Gulch. Pine Gulch flows into Hay Gulch approximately 4 miles below the <br />permit area. Hay Gulch is a tributary of the La Plata River and their <br />confluence is located about 8 miles downstream (southwest) of the King <br />Coal Mine. <br />13 <br />
