Part F Coal Stockpile Pond As-Built <br /> As required by Rule 4.05.9 (14), the following report is provided to document construction <br /> information upon completion of construction. <br /> Design information for the pond is presented in Volume 18, Exhibit 7, Item 23, Part J. The as- <br /> built drawing for the Coal Stockpile Pond is provided in Figure 7-26E-1 and includes plan view, <br /> cross-sections, and spillway details. The final configuration of the pond was adjusted for the <br /> variable topsoil depths encountered during topsoil removal. <br /> The emergency spillway consists of a 2-foot deep rip rap channel with a 20-foot bottom width <br /> and side slopes near 3.OH:IV. <br /> The Coal Stockpile Pond was constructed from mid-August to the first part of September in <br /> 2017, and was regularly inspected throughout construction by a qualified registered professional <br /> engineer. The embankment was constructed with fill material that was free of any unacceptable <br /> fill material as outlined in the Exhibit 7, Item 23, Part K. Compaction, optimum moisture, and <br /> maximum dry density testing was performed in the field during construction of the embankment <br /> and the results of this testing are presented Attachment Exh. 7-2617-1. Final field density tests <br /> indicated a 95% standard or greater compaction was achieved. <br /> The final embankment has been broadcast seeded with the seed mixture outlined in Volume 15, <br /> Section 4.05.6 Sedimentation Ponds. <br /> Exhibit 7 Item 26 Page Exh. 7-23F-1 Revision Date: 6/13/17 <br /> Revision No.: TR-112 <br />
