The proposed contsinment sreas meet the <br />requirements of Rule 1.05.2(3) in that (s) the drsinsge will meet <br />effluent limitations and (b) (i) the drsinsge sres is small and is <br />not mi;ced with underground mine caster discharges. <br />The enclosed calculation sheets show that the contsinment cress can <br />adequately contain the runoff from s 10-year 27-hour storm with out <br />discharging. The contsinment sreas will impound sufficient volume <br />to retain storm runoff, sediment storage snd freeboard. The <br />contsinment pond is constructed below grade, therefore meeting all <br />bank stabilization needs. The total contributing watershed east of <br />the refuse belt is 0.51 acres snd 0.66 acres for the contsinment <br />ayes west of the refuse belt. <br />The sediment snd Surface Water Control Plsn for the Esst Portsl <br />(Map 13) has been revised to show the location of the two <br />contsinment sreas in question. <br />If you have any questions or need additional information do not <br />hesitate to contact this office. <br />Sincerely, <br />~~~ <br />Robert J.
