In the second paragraph on page 2 of Section 2.04.7, WFC states that completion diagrams for nine new monitoring wells are contained in Appendix 2.04.7 -1. Actually only "typical" completion diagrams were provided, one for each of three monitoring zones. Please correct the statement on page 2 as follows: "Typical completion diagrams one each for the overburden, coal zone, and underburden well completion monitoring zones are provided in Figure 1 of Appendix 2.04.7 -1."

The application should contain the specific well completion information for each of the nine new monitoring wells. Table 1 in Appendix 2.04.7 -1 is titled "Proposed Ground Water Monitoring Hole Locations and Depths" and contains "Estimated Monitoring Hole Depths ". This table should be replaced since the wells have been drilled and constructed. Please add a well completion information table to Appendix 2.04.7 -1 that at a minimum contains the following information for each monitoring well: well identification/location, formation monitored, total depth, well casing type and diameter, ground elevation, casing stickup or measuring point elevation, and slotted interval.
