In the Schedule to <br />Notice of Violation, the State identified four steps necessary to abate the violation <br />(remedial action), including: <br />A. Drain water from standing water pond by pump into pond 008. <br />B. Drain water as much as physically possible from the low areas at the top <br />of the pile by installing dewatering ditches that drain toward the west <br />"Reno Mattress" ditch on the front of the pile, leading to pond 008. <br />C. Provide, per 4.09.1(11)a, a certified report by a qualified registered <br />engineer that, in addition to requirements of 4.09.1(11), describes whether <br />the dirt and rock material being added to the pile is allowable under the <br />approved plan. <br />D. If the material is not allowable, then remove it from the pile. <br />In a meeting held May 3, 1993 at MLRD we were requested to complete the report <br />identified in item C above and to provide our opinion of the acceptability of "dirt and rock" <br />which has been incorporated into the pile from a geotechnical perspective. This letter <br />describes the scope of work completed as part of our subsequent evaluation and <br />presents our opinion whether the RDA is being constructed in substantial accordance <br />with the approved mine plan. <br />1571 WEST 12TH Av ENUE DENVER, COLORAD08020~ (303)8250777 <br />
