mentions that, as one of several options , Peabody proposes to utilize <br /> water removed from the respective ponds (dewatering) for "sprinkler <br /> irrigation on the reclamation areas to increase soil moisture". Peabody <br /> recognizes the apparent contradiction, and the following discussion <br /> hopefully will provide clarification. <br /> Dewatering technique No. 4 is one of several options presented in the <br /> aforementioned Appendices . Any pond dewatering at Nucla , regardless of <br /> the technique used, is anticipated only when remedial construction <br /> activities are necessary. <br /> Peabody requests maintaining dewatering technique No. 4 as an <br /> alternative dewatering method. The technique, if used, would involve <br /> redistributing pond water on either pre- or post-law reclamation <br /> upwatershed of the dewatered pond only if the pond water could not meet <br /> effluent limitations using other methods. This would be a relatively <br /> short "irrigation" period with water to be applied to coarse textured <br /> graded spoils containing established vegetation. Implementation of <br /> Technique No. 4 would not cause problems with "weaning" the vegetation <br /> from this "irrigation" as would be expected from a longer term scheduled <br /> irrigation program oriented towards establishment and initial <br /> development of a vegetation stand. <br /> Ground Water Hydrology - (Steve Renner memo, January 16, 1987) <br /> Comment 1. <br /> RESPONSE: <br /> Peabody has revised the second paragraph on page 7-49 of the Nucla Permit <br /> Revision No. 1. The revised text provides a more accurate description of <br /> field conditions . <br /> Comment 2. <br /> RESPONSE: <br /> Peabody intends to consult the Division prior to initiating any proposed <br /> spoils aquifer monitoring in the future. Meanwhile, Peabody has revised <br /> the portion of text discussing spoils aquifer monitoring on Page 7-62 of <br /> the permit revision, providing the Division with discussion on the scope <br /> and purpose of this proposed monitoring. <br /> 4 <br />
