BOWIE RESOURCES LIMITED <br />NEW SEDIMENT POND B CERTIFICATION <br />In accordance with Rule 4.05.6(10), each sediment pond will be inspected during <br />construction under the supervision of, and certified after construction by, a qualified <br />registered professional engineer. This certification is for the construction of Sediment <br />Pond B at the Bowie No. 2 Mine which was constructed during May and June 2000. <br />The construction of the pond was supervised by the undersigned. I have a wide variety of <br />experience in the construction industry and have supervised the construction of numerous <br />sediment ponds. Lambert and Associates performed compaction tests on the pond <br />embankment beginning on May 3151 and ending on June 7'h. The results of the compaction <br />tests are enclosed. <br />Pond B is located near the entrance to the Bowie No. 2 Mine. It is located on the west <br />property line immediately south of old State Highway 133. The design of pond B is shown <br />on Map 22-B, dated 03-21-00. The design calculations for pond B are contained in Volume <br />III, Exhibit 8, page Exh-8-6. An as-built survey of the pond has not been performed. The <br />as designed pond is to contain 4.29 acre-feet of water and 0.62 acre-feet of sediment. To <br />the best of my knowledge and belief, sediment pond B was constructed in accordance with <br />the approved plan. ~~ <br />p~p R~~s <br />a~~ l~ <br />F <br />+ E, <br />p OG+ <br />o~ <br />~ <br />: <br />• ~ <br />~ <br />mes tove~ _ <br />I Engineer <br />~-%~-Od <br />Date <br />~;~ i E <br />..•• <br />
