According <br />to TR 15 and the 1991 Annual Reclamation Report, <br />the above-mentioned ponds were to be surveyed this <br />year. A review of previously submitted data <br />indicates that surveys are not warranted this year. <br />The enclosed summary was extracted from annual <br />reclamation reports and TR 15. Tab 7, Appendix 7- <br />11A presents detailed information on anticipated <br />sediment volumes. The results of the surveys <br />performed to date indicate that sediment delivery <br />rates were overestimated in the design. <br />Peabody requests that the above-mentioned ponds be <br />surveyed in 1993 for sediment. At that time, a re- <br />evaluation will be made regarding frequency of <br />future surveys. <br />Sincerely, <br />. ~`ti'Y CJ. C<J.~,.~~' <br />Gary W.
