N0~ yuv Ant [h~yy~,~l~ oak a'f ~7(.~U <br />Re: MDW Area <br />#1) Why is there no design for the fill structure [Rules 4.10.1(1)/ <br />4.09.1(2) and 2.05.3(8)(a)(i)(E)]? (Note that without a design there is no <br />way to comply with Rule 4.09.1(11)(b), which requires the mine operator <br />to submit a certification from a qualified registered engineer that attests <br />to the fact that #the fill has been constructed as specified in tLhe design <br />approved by the Division. #) ~iYe L~rf ~1 5(~~s ~ p~ 1R ~3 Ko~ddhf ~~-ZT. <br />#2) Where are the mine operator#s inspection reports that address the <br />specific construction tasks identified in Rule 4.09.1(11)(a)?
