<br />NOV C-95-007 <br />2 <br />C~1 <br />3. Runoff conveyed by road ditch HRD-A2 was originally discharged into Pond 006. <br />C~rrrently, HRD-A2 bypasses Pond 006 and its flow added to HRD-MES which is <br />eventually discharged to 006 Gulch through culvert ME-5. Total distance of road <br />drainage conveyed to culvert ME-5 appears to be approximately two miles at an <br />average grade of 3.5%. The haul road drainage system has been modified which <br />has contributed to the excessive quantities of sediment that are being delivered to <br />006 Gulch through culvert ME-5. The current road drainage configuration is not <br />functioning in accordance with the Rules and Regulations, a TR is required. <br />Please contact me if you have any questions or require additional information. <br />Sincerely, <br />/~-~~~~ ~~~' <br />Wallace H.
