Long <br />D~. ision Director <br />RE: Colowyo Co~, Mine - "Section 16 Fill" Response Letter <br />ermit No: C-81-019) <br />I have finally gotten enough of a respit from the Summitville <br />Fiasco to review Colowyo's response to my November 6, 1992 comment <br />letter, dated November 13, 1992. <br />Colowyo's response, prepared by Jim Kilter and Robert Trumbly, P.E. <br />appropriately rspond to my early concerns. They have appropriately <br />described their logic in field location and design of the <br />underdrain in the toe area of the Section 16 Fill. My preliminary <br />examination of Colowyo's January 22, 1993 inspection report for the <br />Section 16 Fill, ascertained that the appropriate design <br />documentation and photographic evidence is provided for the <br />underdrain construction. <br />Therefore, while its relatively mute at this late date, I recommend <br />acceptance of the November 13, 1992 supplemental submittal for the <br />Section 16 Fill adequacy response. It appears that the underdrain <br />beneath the toe area of the fill has been properly constructed and <br />certified. <br />cc: Larry Router <br />JP/7P <br />
