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