WWL spent the next several hours locating and marking the other manholes along the <br /> retort pipeline. All of the manholes located on Logan Wash Road are buried under the road. A metal <br /> detector was used to identify manhole locations. MH-14 was uncovered by hand excavating, opened <br /> and checked for the presence of sediment and sludge. Good,unrestricted flow was observed at MH-14 <br /> (this was at approximately 1:00 PM). By the time the remaining manholes were located at 3:30 PM, <br /> retort water was flowing freely to the Lower Manhole (NIFI-2) and the Evaporation Pond Facility. <br /> Because flow was re-established to the Pond,no further investigations or maintenance were conducted. <br /> WWL will submit the results of the soil sample analytical data, once received from the laboratory. At <br /> that time,the need for soil remediation will be evaluated. <br /> Should you have any questions,please contact me at(970)242-0170. <br /> Sincerely, <br /> / Nl� 2X2Z-- k <br /> Bruce D.
