<br />June 28, 1995 Page 5 <br />Sediment Pond Inspection Reports <br />Requirements <br />* Rule 4.05.6(13) requires that the sediment ponds be inspected on <br />a quarterly basis for structural weakness, erosion, and other <br />hazardous condition. In addition, the report should include the <br />level of sediment in the pond. <br />Compliance and Adeouacy Ouestions <br />* The pond inspection reports are done on a quarterly basis as <br />required and general information about the pond is provided as <br />required. However, a specific level of sediment is not included in <br />the report; only general information regarding where sediment has <br />accumulated and a recommendation to clean the pond is included. I <br />assume that the pond designs specify a maximum sediment elevation. <br />While the general information provided in the report regarding <br />sediment in the pond is useful, the inspection report should <br />reference the maximum elevation identified in the pond design. <br />Question: In future pond inspection reports, EFCI should <br />identify the amount of sediment in the pond compared to the <br />maximum sediment elevation specified in the pond design. <br />Question: It appears that a majority of the time, the <br />engineer's recommendations regarding pond maintenance is <br />disregarded because the same recommendation appears in more <br />than one report. EFCI should comment. <br />This concludes my review of the quarterly pond and refuse pile <br />inspection reports. Please let me know if you need more <br />information or would like me to follow up this memo to you with a <br />letter to the operator. Please let me know if you have any <br />questions. <br />CEJ/014REP01 <br />
