2. DRMS 07/22: New Appendix 2.05.3(4) -7 has been provided with this application. The <br />Division notes that throughout this Appendix, nomenclature used to identify the ditches is <br />inconsistent with that used in the Arcadis design report of Appendix 2.05.3(4) -1. In the <br />Arcadis design, and throughout the approved permit text and maps, the ditches are named <br />"NHN -001 West" and "NHN -001 East ". The new text and maps refer instead to "Pond <br />001 Ditches" or "Pond NHN -001 Ditches ". Please modify the various texts and maps <br />submitted with this application to be consistent with the nomenclature already established <br />for these features. <br />DRMS 09/09: The names were changed in some instances, but not in all. Please refer <br />to the attached photocopies for specific locations that remain to be corrected. <br />Pages 2, 3, and 15 of Appendix 2.05.3(4) -7 have been revised to reflect the nomenclature of <br />the existing permit. When the pond is referred to, "Pond NHN -001 " is used, when the ditches <br />are referred to either, "NHN -001 Ditches ", "NHN -001 East ". or "NHN -001 West" are used, <br />as appropriate. Additionally, Maps 2.05.3(4) -7 and 2.05.3(4) -8 have been revised based on the <br />notes provided in the adequacy review. <br />DRMS 07/22: The new Appendix provides an analysis of the ditches that were <br />constructed. However, the narrative does not refer back to the original approved design, <br />and fails to describe why significant modifications to the ditch geometry (triangular <br />versus trapezoidal) were instituted during construction. <br />DRMS 09/09: Some discussion was provided about the selection of a triangular design. <br />However, the text still does not provide a reference to the approved design. Please insert <br />a reference to Appendix 2.05.3(4) -1 of the permit, which is where the approved ditch <br />designs are found. <br />A reference to Appendix 2.05.3(4) -1 has been added to page 1 of Appendix 2.05.3(4) -7. <br />4. This item is resolved. <br />5. DRMS 07/22: Map 2.05.3(4) -8 illustrates typical cross sections of the ditches, but <br />neither this map nor the narrative provides the required depth and width for the ditches <br />and half - culvert. Please incorporate width and depth information, by ditch segment, into <br />the permit. <br />DRMS 09/09: The Channel Properties section of Table 2.05.3(4) -7 -2 was updated, as <br />requested, to include information on the channel depth and width. The information <br />provided appears to have been mathematically derived from the required channel <br />capacity section of the table, and it is not clear whether the dimensions were actually <br />measured in the field. Since this Appendix is intended to provide as -built information, it <br />should provide widths and depths that were measured in the field. Please review, and <br />comment or revise as appropriate. <br />The channel depth and width information in Table 2.05.3(4) -7 -2 is measured based on cross <br />sections of surveys of the ditches. A note has been added to the table explaining this. <br />
