As we discussed, the water storage operator (Central <br />Colorado Water Conservation District) for the Koenig pit has repaired the slurry wall and is in the integrity testing <br />period as required by the Office of the State Engineer. We anticipate approximately at least another month will be <br />needed by the operator and the State Engineer to complete the testing and analysis of results. Upon completion of <br />the slurry wall integrity test, the State Engineer will review the data and determine whether a SWSP is needed. <br />We will send you a copy of the State Engineer's correspondence as soon as we receive it. <br />Please accept this extension request letter as a follow -up to our discussion regarding the Substitute Water Supply <br />Plan filing requirement for the Koenig Pit (M -1980 -120). <br />We thank you for your consideration in this matter. <br />If you have any questions or need additional information, please feel free to contact me or Clay Kimmi at <br />(970)304 -6496. <br />David Bauer, P.E., CFM <br />County Engineer — Development <br />Cc: Randy Ray, Central Colorado Water Conservation District <br />Joanna Williams, David Nettles, Colorado Division of Water Resources <br />K /Dave B/WaterRights /Koenig SWSP Extension Request - DRMS 12 -23 -09 <br />
