Permit C-022-81 contains designs for <br />14 sedimentation ponds (Appendix B). All of the sedimentation ponds were con- <br />structed under RU' supervision and to the best of my knowledge, the ponds were <br />constructed using prudent state-of-the-art construction methods. <br />I inspected the sedimentation ponds both during construction and after con- <br />struction was completed. Where the constructed pond differed significantly <br />from the design, "as constructed" drawings were prepared and submitted to <br />the Division. To the best of my knowledge, the sedimentation ponds were <br />constructed according to the drawings referenced in Exhibit A and in accord- <br />ance with the design specifications of Appendix B permit C-022-B1. To the <br />best of my knowledge the sedimentations referenced in Exhibit A are in com- <br />pliance with U. S. ,Steel Mining Co., Somerset Mine permit C-022-B1. <br /> <br />- i - _6 ~ - _: --~ R <br />W. P. Reitze Regis ed Professional Engineer ~~~;o. 19690 <br />n:a ••~• <br />~I.
