Lawrence & Ottenhoff <br />1011 - 11 t° Avenue <br />Greeley, CO 80631 <br />Re: Western Muturai Ditch - S&H Mine <br />Deat 1<:irrt: <br />I hav: reviewed the information packet provided to Frank Praeer, Esq. This packet contains the <br />appli~:tttion to the Division of Minerals and Geology (DMG), S&H's proposed mining plan and <br />reclamation plan, in addition to numerous letters of correspondence between S&H's consultant, <br />the I: AdG and several state agencies. I noted that the DMG has been very diligent in identifying <br />issue; and requiring S&H to address these issues. May of the issues that I initially identified as <br />area; of concern for Western Mutua! were identified and subsequently addressed by S&H. The <br />following aze items that I feel that were not adequately addressed by S&H and may impact <br />ease; n~;nts owned by Western Mutual. <br />The proposed mining plan does not provide for a detailed description of the 1 acre de- <br />watering proposed by S&H. Western Mutual owns numerous alluvial wells on.the west, <br />side of the South Platte River which may be impacted by any de-watering on the S&H <br />site. Western Mutua] should required S&H to present a detailed de-watering plan that <br />includes: <br />1, the exact location of the proposed de-watering pits, <br />b, be limited tp no more then one de-watering pit during any water yeaz, (this is <br />implied in the Leonazd Rice report in that only one small pit was analyzed) <br />c, identify the exact location of the dischazge of water from the de-watering <br />operation, <br />d. the de-watering will result in substantial seepage loss to the Western Mutual ditch <br />which S&H has not proposed to replace, <br />d. and provide Western Mutual with an application for an NPDES permit and allow <br />for Western Mutual to be active in the development of the terms and conditions of <br />LEAF ENGINEERING <br />Hydrology~Hydrauiics' Water Resources' Water Quality <br />E:LLe.i \\Vestern MuNalV.awrence Western Mu[ual Injury Letter.sspd <br />
