Susan Burgmaier -2- September 24, 2014 <br />and revise the appropriate text pages and maps for consistency. <br />BRL: Culvert G -1 has been removed from the permit application. Please see revised <br />Map -20, and Map 15 -1. <br />4. Revised pages Exh -8 -32ii through Exh -8 -32ix will replace existing pages Exh -8- <br />32ii through Exh -8 -32vi. The currently approved permit application has a blank page <br />Exh -32ii (referring reader to G -2, G -3, and G -4 designs on page Exh -8 -254, approved <br />with TR -84) and the designs for Culverts B3, B12, C8, and C7 are on pages Exh- 8 -32iii <br />— Exh -8 -32vi. Please repaginate the proposed pages for Culverts C -22, C -23, C -24, <br />and K2 so that the design information for the aforementioned G, B and C culverts <br />is not removed from the permit application package. <br />BRL: The pages have been repaginated for Culverts C -22, 23, 24 and K3. Please see <br />revised pages EXH -8 -32ix - EXH- 8- 32xxvii, Exh. 8 -29 & 31, and page Exh. 8 -741ii. <br />Since the designation for Culvert C -22 was re -used with this revision, and now adds <br />flow to Ditch C -18, the summary page (Exh. 8 -74ii) for ditch C18 had to be revised. <br />Therefore, pages Exh. 8 -29 & 31 had to be updated as well. <br />5. Revised pages Exh -8 -32i through Exh -8- 32viii: The page between Exh -8 -32vi <br />and Exh -8- 32viii is labeled Exh -8 -vii. Please revise the page number to read "Exh -8- <br />32vii ". <br />BRL: Old page Exh -8 -32 -vii, which was the design for Culvert C -22 is now begins <br />on page EXH. 8 -32ix and the error has been corrected. <br />6. While reviewing the updated design information for Culvert C -13, we were unable <br />to locate design information for Culverts C4 and C5. It appears that the design <br />information for these culverts may have been inadvertently removed from the permit <br />application in a prior revision. Please indicate the location in the permit application <br />package for the designs of Culverts C4 and C5, or resubmit the design <br />information for reincorporation in the permit application package. <br />BRL: Before wide spread use of SedCad, unless a culvert had a drainage area, it was <br />sized using a nomograph in accordance with the handbook of Steel Drainage & <br />Highway construction as discussed on page 2.05 -28 in the permit. Therefore, many of <br />the culverts do not have a detailed design associated with them. However, as we <br />proceed with permit revisions, updating of the culverts as needed with SedCad is a <br />reasonable request in bringing the permit up to current design standards. Please see <br />designs for Culverts C4 & C5 on pages Exh. 8 -32 vii & viii. <br />7. Revised page 8 -29 includes a listing, and revised Map 15 -2 includes a <br />designation, for new ditch D -C25. There does not appear to be any design information <br />provided for this new structure. Please provide design details for ditch D -C25, or <br />identify the location of the design information in the currently approved permit <br />
