I understand that you may use this same <br />analysis for that application, but it is confusing to have that in the heading. This is a separate (albeit related) <br />issue. <br />Why is there only one analysis when you have two ponds? Please explain why this makes sense to combine the <br />two analyses into one. <br />I need more information on where on the maps you measured length and slope to calculate the LS factor. <br />Can you elaborate on how you obtained the cover percentage (for C factors) from the IME studies? <br />Thank you, <br />Rob <br />Rob Zuber, P.E. <br />Environmental Protection Specialist II <br />Coat Regulatory Program <br />COLORADO <br />Division of Reclamation, <br />Mining and Safety <br />Department of Natural Resources <br />P 303.866.3567, extension 8113 1 F 303.832.8106 <br />1313 Sherman Street, Room 215, Denver, CO 80203 <br />rob.zuberCstate.co.us I http: / /mining. state. co. us <br />https: / /mail.google.com /mail /u /0 / ?ui= 2 &ik= e29129fcb5& view =pt& search = inbox& th= l4880533b744aa35 &siml= 14880533b744aa35 1/1 <br />
