Flow from the Wadge Coal to the lv'olf • <br />Creek Coai is indicated near the nose of the Tow Creek anticline. <br />This situation is reversed on the east limb of the anticline. <br />Peabod_v's revised potentiometric surface map should be further <br />evaluated to reflect the location of springs and seeps in and near <br />the Permit area. The potentiometric surface should reflect the <br />avaiiable data, not topographic contours. Areas which are <br />unsaturated should be indicated as such on the mad. The <br />potentiometric map should be periodically updated as spoils <br />monitoring wells are drilled and data becomes available. <br />'ESPOh+SE: <br />Discussions with C."L RD on September 30th clarified Peabody's assumptions <br />in developing the potentiometric surface map. It was agreed that based <br />~n tie available data and assumptions, the potentiometric and water <br />radio surfaces :;euid not require inooification. <br />N11 known springs ana spoils springs have been included on Exhibit 7-2A. • <br />areas cf ,-.inimal saturation in ste spoils are discussed in Tab 7, <br />Section VII B.2.a. <br />In the discussion in Tab 7, Section VII B.2.a., Peabody has committed to <br />updating E hi bit ;-tA periodically as part of the annual hydroloe}~ data <br />reports. <br />COi iMEPlT: <br />3. Peabody intends to install a series of monitoring wells to define <br />ground ~.vater flow in the spoils. Placement of the wells is <br />generally acceptable. The monitoring pronram could be improved b~ <br />nlacinp a spoils ~vei1 near 18500E, "g500S and by adding <br />piezometers, or v:e11s, to determine the differential heads of the <br />tJo]f Creek Coal and :•!adge Coal at this location. <br />RESPONSE: ~ i <br />Based on agreements reached :rith Ch1LRD cn September '0th, Peabody has <br />deleted the proposed higher uperadient spoils wells and has concentrated <br />16 <br />
