• Susan Burgmaier -3- January 28, 2014 <br />no interest in removing it at this time. Please see revised Maps 15 -2, 21 -2 and 20. <br />The disturbed area boundary increased by 5.0 acres with the approval of TR -89, please see the <br />revised disturbed area boundary on Map 18. Since topsoil distribution will not change with TR- <br />91, Map -32 will be revised under revision TR -98. <br />A ditch segment was removed from the access road north of the D- Bench. The segment was <br />un -named but presumably part of Ditch C -12. No revisions to the summary sheet for C -12 are <br />necessary since runoff will still enter the lower segment of the ditch. <br />A water bar is shown north and east of Ditch D -4 on Maps 15 -2 and 21 -1, but was not shown on <br />Map -20. Please see revised Map -20. The hydrology summary shown on page Exh. 8 -62 for <br />Ditch D -4 was reviewed and it is sized appropriately to accept runoff from the flow diverted by <br />the water bar. <br />Reconstruction of the East Diversion ditch was approved with TR -89, and, the ditch has been <br />recently constructed, but with a slightly more gentle grade. Please see revised designs on <br />pages App. B -60 and 60i, and the ditch summary sheet, page App. B -2. <br />Please feel free to contact me if you have any questions. <br />Sincerely, <br />lLtiflrn •r ri Q4- s,�p' <br />Tamme Bishop, P.E. <br />Project Engineer <br />Revised Pages: <br />Volume II: Maps 15 -2, <br />Volume III: Pages Exh. <br />Volume IX: Pages App. <br />Volume XI: Pages App. <br />15 -3, 18, 20, 21 -2, 21 -3, <br />8 -29, 31, 32, 60, 61 & 62 <br />B -2, 60 & 60i <br />B -2 & 78, 78i <br />Cc: Bill Bear, Bowie Resources, LLC (electronically) <br />Paonia Public Library <br />Bureau of Land Management (electronically) <br />US Forest Service (electronically) <br />
