POND CAPACITY - ACRE FEET <br />Water <br />Sediment <br />Total <br />3.82 <br />0.18 <br />4.00 <br />BOWIE RESOURCES, LLC <br />SEDIMENT POND F CERTIFICATION <br />In accordance with Rule 4.05.9(14), impoundments shall be inspected during <br />construction and upon completion of construction by a qualified registered professional <br />engineer or other qualified specialist under the direction of a professional engineer. <br />This certification is for the expansion of Pond F as associated with approved technical <br />revision no. 72. <br />The expansion of the pond was completed in early June, 2012, and verified with a field <br />and topographic survey in July, 2012. I have a wide variety of experience in the design <br />and construction of earth fill embankments and impoundments. Nothing was observed <br />during the inspection that would indicate the pond has a potential for failure. There was <br />no appearance of erosion, instability, structural weakness or other hazardous <br />conditions. There are no required monitoring procedures or instrumentation other than <br />quarterly and yearly inspections. There are no aspects which might affect stability and <br />there is no required maintenance. There was no water impounded during the <br />inspection. <br />The sediment pond was, with minor exceptions, constructed in accordance with the <br />approved plan during June, 2012. The design of the sediment pond is shown on Figure <br />3, Volume IX. The as -built capacity of the pond is as follows: <br />The minor exceptions mentioned above are associated with how the pond was <br />constructed. During construction a I.. •,:,� • k segment was encountered on the <br />southern edge of the planned e -.- r`. 'sir ,•ond. Therefore, the pond is slightly <br />smaller than the pond design ° ''i ' 4 �r ; '� , but large enough to handle the <br />projected water and sedimen ol_ s. �`e% <br />���•.t ,,.,, fi r; , 6 1- t v% <br />Ta ��' K. tov ' . op Date <br />Co 4. is , , Prof '.l'.:: I Engineer <br />� � , Q' ..... <br />o. 43402 <br />
