R'~ Ai!G~ I GIVI~10~1 <br />We are writing this letter to confirm Julian Mitchell's verbal <br />conversation with you today regarding Blue Ribbon's efforts with <br />respect to abatement of the violation which requires us to re- <br />establish positive drainage on the portal bench on or before <br />April 13, 1984. As Julian reminded you, the bench repair to <br />re-establish positive drainage was originally accomplished on <br />March 29, 1984. You will recall that we showed you "before" and <br />"after" repair slides to confirm what we had completed by that date. <br />Unfortunately, additional movement has occurred since March 29th. <br />That movement has been significant enough to again require addi- <br />tional grade work to maintain drainage which you require. <br />We have employed a contractor to do dozer work to create that <br />positive grade from roughly the area where the coal screen is <br />usually installed to the catch basin near the outer edge of <br />mine bench. The dozer was on site at the time w <br />i. e., 3:45 p.m. The dozer work of filling the 1 <br />outer mine bench and establishing a positive gra <br />The contractor's dozer will be kept at the mine <br />bench will be re-examined at 7:00 a. m. tomorrow, <br />work is required. <br />e wrote this <br />ow areas in <br />the <br />letter, <br />the <br />de was just completed. <br />overnight, and the <br />in case additional <br />Management for Blue Ribbon has assigned complete re-assessment, <br />and a related engineering survey and study is under way to examine <br />options which may be more successful with relieving the stability <br />concerns on the mine bench. When this assessment is complete, we <br />would like to discuss mine bench stability with MLR at some length. <br />Very truly yours, <br />~" V lJl~-~ <br />William S.
