Page 6of10 <br />... A staff gage will be installed on or adjacent to the riser pope of Pond 007 identifying <br />the water level (7373.3 ft.) adequate to retain a 10 year 24 -hour storm without <br />discharging over the emergency spillway. This elevation was arrived at through a review <br />of the Pond 007 as -built stage volume curve dated 5131185 in Exhibit 19. The crest invert <br />emergency spillway volume is 9.2 acre feet and the 10yr 24 -hr runoff volume is 6.6 acres <br />feet, resulting in an allowable permanent storage and sediment volume of 2.6 acre feet. <br />n. Given the nomenclature difficulties surrounding development waste disposal areas, and <br />the uncertainty surrounding the permitting of future piles, it may be prudent to change <br />the wording in the paragraph that reads: <br />All materials removed through the cleaning or excavation of sediment and/or treatment <br />ponds will be disposed of at the development wastes pile <br />to read: <br />All materials removed through the cleaning or excavation of sediment and/or treatment <br />ponds will be disposed of as development waste <br />o. Table 20 — Ditch Data. It would be preferable if the table were to start on a new page <br />and fill as few pages as possible. The header row should be repeated on each new page. <br />Several cells are marked with an asterisk, the explanation of which should be restored. <br />The depth header should be qualified with the statement that it includes freeboard. <br />p. Table 21— Culvert Data. As above, it would be preferable if the table were to start on a <br />new page and fill as few pages as possible. The header row should be repeated on each <br />new page. Some of the in -text indicators for numbered footnotes have been deleted and <br />should be restored; those that remain should be restored to super - script. Where culverts <br />have been removed, the table rows should be deleted. <br />q. Table 22 — Culvert Sizing Nomograph. Although the "table" may be more of a figure <br />than a table, it is described as a table, and should therefore be restored to its place in the <br />text. <br />r. Table 2' ) — Sediment Pond Dimensions. The in -text indicators for numbered footnotes <br />should be restored to super- script. <br />s. Pond 001 —Emergency Spillway Design. One of the design criteria has been deleted — <br />why was this? <br />t. On page 2.05 -31 there are some typographical errors: <br />the Division has approved the probably hydrologic consequences... <br />the Division's review of THE OPERATOR's plans... <br />u. Section 2.053(4) — Topsoil: This section will need to be re -written in order to satisfy <br />the requirements of MT6 (26). Redundant or out -of -date text should be deleted and the <br />remaining text should be revised to provide as concise a description as possible of how <br />topsoil is to be managed at the mine. In the text, every existing topsoil pile should be <br />identified with a name and a description of where it is — at present "Topsoil pile no. 2" <br />is mentioned in the text, but its location is not described; Map 11, sheet 3 has a labeled <br />"Topsoil pile" in the soil storage area to the west of pond 1; Map 13 has an area labeled <br />"Topsoil Stockpile 42" between the river and the highway and west of the refuse <br />conveyor (which does not exist on the ground). Further, an estimate of the quantity of <br />
