Coal and underburden. Water level monitoring conducted at these three <br /> wells since installation indicates that the three units in the vicinity <br /> of Mining Areas 2 and 3 are dry. Additionally, mining in Areas 2 and 3 <br /> will only occur to depths of 20 to 30 feet. Because of these factors , <br /> Peabody does not feel that there will be any potential for measurable <br /> resaturation of the spoil in these mining areas. Peabody will continue <br /> to monitor Wells GW-N23, GW-N24 and GWN25 for any indication of <br /> resaturation. <br /> Comment 5. <br /> RESPONSE: <br /> Peabody has developed a generic well completion schematic that reflects <br /> the characteristics of all proposed spoils monitoring wells at Nucla. <br /> Information on materials used for the casing, gravel pack and grout, as <br /> well as general specifications on annular spacing, screen openings and <br /> casing diameter have been provided on the schematic. The generic <br /> well completion schematic for the proposed spoils monitoring wells has <br /> been inserted in the Nucla Permit Revision as Figure 7-49a (page 7-136a) <br /> and in the Nucla 1986 AHR as Figure 16a (page 72a) . Also, small portions <br /> of text pertinent to the generic well completion schematic have been <br /> revised. These text revisions can be found on Page 7-131 of the Vucld <br /> Permit Revision, and Page 67 of the 1986 Nucla AHR. <br /> Comment 6. <br /> RESPONSE: <br /> Peabody has revised Exhibit 1 of the 1986 AHR for Nucla and Exhibit 7-8 of <br /> the Permit Revision to correct discrepancies concerning completion <br /> information on Wells GW-N11 and GW-N9. No text revisions in either the <br /> 1986 Nucla AHR or the Nucla Permit Revision No. 1 were necessary. <br /> Comment 7. <br /> RESPONSE: <br /> Peabody agrees with the Division 's suggestion that monitoring Well GW-N1 <br /> for water quality on an annual basis would be beneficial for determining <br /> the long term accuracy of Peabody's statements in the Permit Revision <br /> regarding probable hydrologic consequences. Beginning in 1987, Peabody <br /> will monitor GW-NI for the same list of water quality parameters <br /> 6 <br />
