Louis Head <br />Page 2 <br />February 11, 2016 <br />28. Ditch D61 along the haul road to the RDA was found to be smaller than the specification in the <br />PAP. Table 20 indicates that this ditch should be 9 feet wide and 1.8 feet deep. The actual ditch <br />is approximately 6 feet wide and 1 foot deep where it was measured. NECC needs to determine <br />if the table should be updated (based on modeling) or if the ditch needs to be enlarged to meet the <br />specification. <br />29. Near the RDA entrance from the highway, Map 13 shows a culvert that does not exist; also in this <br />area of the map ditch D67 should be extended to the west to accurately show what is on the <br />ground. <br />Please feel free to contact me with any questions or comments. <br />Regards, <br />Robert D. Zuber, P.E. <br />Environmental Protection Specialist II <br />Cc: Ron Thompson (via e-mail) <br />
