You will <br />notice that the accompanying information summarizes the methods for <br />determining the maximum amount of explosives in an eight ms period. <br />In the future, all blasting reports will accurately reflect the <br />maximum amount of explosives per eight ms period, instead of the amount of <br />explosives per row or delay. <br />Also, be advised that on November 17, 1983 we completed the <br />seeding of the topsoil area of concern during your inspection. <br />Should you have any additional questions please contact me. <br />Sincerely, <br />COLOWYO COAL COMPANY <br />CW~`w ~ .
