site for three to four weeks in July, 1997. They are interested in <br /> accomplishing erosion control work, watershed protection and <br /> restoration work as well as tree planting. A detailed project <br /> proposal will be submitted to AmeriCorps by March 28, 1997. <br /> AREAS OF CONCERN <br /> There are a number of items which the Division and the Attorney <br /> General will need to keep track of as 1997 progresses. <br /> Spring Runoff 97 <br /> The snowpack within the Crystal River drainage basin, as with most <br /> of Colorado, was above average at the beginning of 1997. The <br /> potential exists for an above average spring runoff to occur. As <br /> is usual at Coal Basin, this could present many different problems, <br /> not the least of which would be failures of the old Refuse Pile <br /> east of Dutch Creek and south of the warehouse area. Little, if <br /> anything, can be done to avoid such an occurrence at this time. <br /> However, monitoring and post failure remediation to ensure that <br /> damming of Dutch or Coal Creeks does not occur may be necessary. <br /> Flume Failure <br /> The flume was observed periodically throughout the spring, summer <br /> and fall of 1996. The repair of the base of the flume accomplished <br /> in 1995 appeared to be successful. No further deterioration of the <br /> base of the flume was observed. No changes to the underside of the <br /> flume, where it is exposed for the last fifteen feet or so, were <br /> observed. Neither was significant deterioration of the flume <br /> foundation, about forty feet below the crest of the flume, <br /> observed. However, as discussed in previous reports, these areas <br /> have not appeared to be structurally sound for quite some time. A <br /> significant runoff event could contribute toward deterioration of <br /> the flume, causing its failure. The last fifteen feet of the flume <br /> and the foundation will need to be regularly observed in case signs <br /> of imminent failure can be detected during the spring and early <br /> summer. It is thought that little, if anything, can be done to <br /> prevent a failure. Mitigation of the impacts of a failure could be <br /> undertaken dependent upon the impacts of a collapse of the flume. <br /> An engineering analyses would be required in this circumstance. <br /> Ponds <br /> One sediment pond (the 009 pond) is located half way up the Old <br /> Refuse Pile at the top of the old belt line. This pond drains into <br /> the so called grey water pond located opposite Dutch Creek from the <br /> office. The discharge structure at this pond has a tendency to <br /> become blocked by organic debris, thus creating the potential of an <br /> overtop. Water discharging from the top of the pond will likely <br /> 22 <br />
