Lewicki & Associates C -2010 -089 / TR -04 / PAR -2 09 -Sep -2013 Page 2 of 3 DBMS 09109: The majority of items were updated with the response, as requested. However, the title of Appendix 2.05.3(4) -6 should be, "Pond NHN- 001 As- Built" and Appendix 2.05.3(4) -7 should be titled, "NHN -001 Ditches As- Built ". Please revise these two titles in the TOC. 2, DBMS 07/22: New Appendix 2.05.3(4) -7 has been provided with this application. The Division notes that throughout this Appendix, nomenclature used to identify the ditches is inconsistent with that used in the Arcadis design report of Appendix 2.05.3(4) -1. In the Arcadis design, and throughout the approved permit text and maps, the ditches are named "NHN -001 West" and "NHN -00I East ". The new text and maps refer instead to "Pond 001 Ditches" or "Pond NHN -00I Ditches ". Please modify the various texts and maps submitted with this application to be consistent with the nomenclature already established for these features. DRMS 09/09: The names were changed in some instances, but not in all. Please refer to the attached photocopies for specific locations that remain to be corrected. 3. DRMS 07122: The new Appendix provides an analysis of the ditches that were constructed. However, the narrative does not refer back to the original approved design, and fails to describe why significant modifications to the ditch geometry (triangular versus trapezoidal) were instituted during construction. DRMS 09/09: Some discussion was provided about the selection of a triangular design. However, the text still does not provide a reference to the approved design. Please insert a reference to Appendix 2.05.3(4) -I of the permit, which is where the approved ditch designs are found. 4. DRMS 07122: The as -built designs refer to segments of ditch having been lined with 3" and 6" riprap. During numerous site inspections, Division personnel have not observed that riprap of any size has been used to armor the NHN -001 East and West collection ditches. Please revise the application to accurately portray and evaluate the armoring system used for certain segments of these ditches. DRMS 09109: Appendix 2.05.3(4) -7 text (page 1) was expanded to address the materials used in armoring specific sections of the NHN -001 ditches. This item is resolved 5. DRMS 07/22: Map 2.05.3(4) -8 illustrates typical cross sections of the ditches, but neither this map nor the narrative provides the required depth and width for the ditches and half - culvert. Please incorporate width and depth information, by ditch segment, into the permit. DBMS 09/09: The Channel Properties section of Table 2.05.3(4) -7 -2 was updated, as requested, to include information on the channel depth and width. The information provided appears to have been mathematically derived from the required channel capacity section of the table, and it is not clear whether the dimensions were actually measured in the field. Since this Appendix is intended to provide as -built information, it
