Lochhead <br />Execulrve Duetlor <br />Michael B Lang <br />Division Direcmr <br />Re: Eckman Park, -81-071, and Foidel Creek, C-82-056, Quarterly Pond <br />Inspection Reports. <br />Dan, You asked me to comment on Eckman's and Foidel quarterly pond Inspection Reports <br />in respect to Rule 4.05.6(13). I do have a couple problems with the reports that I will <br />discuss with mine personnel next week while I am in the field. <br />The first discrepancy I noted was Pond A at Eckman. The "lowest hole" elevation is <br />recorded to be 6934.5 ft. while the water level is reported to be 6933.6 ft. Only problem is, i 6 <br />the report states that a discharge of 1.121 cfs is occurring. I will discuss this with the 'C~ P <br />inspector, Tavis Rogers. <br />On both Eckman Park pond D, and Foidel Creek treatment facility there was a notation of <br />burrows on the inside of the embankment. No detail to what elevation the burrows are, <br />extent or size was provided. If there are burrows on the inside of the embankment, this <br />could be a potential problem unless they are above potential water levels (above the <br />emergency spillway discharge). I will ask the operator to include more information on this <br />item. <br />Also, on Pond A, I believe it is an MSHA pond (< 10 acre.ft. or embankment > 20 ft. high) <br />We have not been provided a copy of an MSHA report or proof of filing of the report as <br />per Rule 4.05.6(13)(b). D ~ <t ~• !/1311~-- <br />I would also like additional information included on Pond B. It is unclear from the <br />submitted report_where the spillway discharge level is. w<<l fx.. ~.r+; f.'..r ~ NR .-w;tt ~~ <br />se;4~ ,,,.,y 9.,~,.~ <br />I will inquire into theses items. I can discuss these with you further when I return from the <br />field. <br />
