CERTIFICATION <br />On January 12, 1993 I reviewed the as-built survey of the 001 <br />Explosives Storage Area Pond to determine its compliance with CMLRD <br />Rule 4.05.6(3)(d) requiring that this pond be fitted with two <br />separate spillways separated by an elevation difference of at least <br />one foot. <br />I am a registered Professional Engineer in the State of Colorado <br />and am experienced in the design and supervision of earthen <br />construction. I have reviewed the certified survey of this <br />structure performed by Peter Epp (Colorado P.L.S. No. 14815) on <br />December 22, 1992. I have also reviewed the previous as-built <br />certification by Jerry E. Snider (Colorado P.E. No. 17570) dated <br />April 14, 1986. In addition to the above, I have discussed the <br />modification made in 1992 with Juan. P. Garcia who supervised the <br />actual modification. This modification to bring this structure in <br />compliance with CMLRD Rule 4.05.6(3)(d) was to add a 6" CMP at an <br />elevation 1' below the original 18" CMP spillway. The 6" CMP is <br />now the primary spillway and the 18" CMP is now the emergency <br />spillway. <br />I hereby certify this modification as bringing this structure into <br />compliance with CMLRD Rule 4.05.6(3)(d). <br />_ ~i~/ <br />Robert G.
