Where appropriate, runoff, sediment yield, and flow velocity calculations <br />are provided to quantify the limited nature of hydrologic impacts. <br />Attached to this transmittal is a Summary of Revisions/Additions providing placement <br />instructions for the revised materials. <br />Please review the accompanying transmittal and feel free to contact me with any <br />questions or comments. We look forward to your timely response. <br />Sincerely yours, <br /> <br />Allen S. Weaver <br />cc: Randy Acre <br />Brad Doores <br />Jerry Nettleton <br />
