Mr. Richard Raines Page 7 <br />Middle Poudre Combined Plan -Lafarge West, Inc. January 26, 2007 <br />11. All parcels of dried up land used to generate augmentation credits will be inspected <br />during the irrigation season to verify dry-up. The final verification of dry up will be in the <br />form of an affidavit signed by an individual having personal knowledge of the dry up for <br />this year's entire irrigation season for each parcel of land used in this SWSP. All <br />affidavits must be provided to the division engineer by November 15, 2007 in order that <br />the final determination of augmentation credits for the irrigation season can be made <br />along with mapping showing any revisions to the dry up acreage. Credit from any dry-up <br />fields containing alfalfa or native grass will be assessed in the following manner: <br />(a) For fields deep tilled or chemically treated to successfully kill alfalfa or native <br />grass, 100% credit will be given for consumptive use as otherwise computed <br />under the conditions of this approval. <br />(b) For fields not deep tilled or chemically treated to successfully kill alfalfa, records <br />of monthly monitoring of depth to groundwater at existing irrigation wells or <br />existing or new monitoring wells or piezometers within'/<-mile of each alfalfa or <br />native grass field must be maintained. Credits will be reduced according to the. <br />following table when depth to groundwater is less than the depth assumed to <br />provide no significant contribution to alfalfa growth. Measurements taken at the <br />start of each month will determine the necessary reduction in credit to be applied <br />during the following month. The applicant may use another methodology upon <br />review and approval by the State Engineer and Division Engineer, <br />Depth to Ground <br />t <br />W <br />F Percent Reduction in CU Credit' <br />ater ( <br />ee <br />) <br />Native Grass <br />Alfalfa <br />1 85% 100% <br />2 50% 90% <br />3 30% 75% <br />4 20% 50% <br />5 15% 35% <br />6 10% 20% <br />7 5% 15% <br />8 0% 10% <br />1. Adapted from EVAPOTRANSPIRATION AND AGRONOMIC RESPONSES IN FORMERLY <br />IRRIGATED MOUNTAIN MEADOWS,Soufh Park, Colorado, March 1, 1990; Revised September 1, 1991 <br />12. This substitute water supply plan may be revoked or modified at any time should it be <br />determined that injury to other vested water rights has or will occur as a result of this <br />plan. Should this supply plan expire without renewal or be revoked prior to adjudication of <br />a permanent plan for augmentation, all use of ground water must cease immediately. <br />13. Lafarge, West, Inc. filed for a plan for augmentation for the Port of Entry Pit site in case <br />no. 2004CW 111 and filed for a plan for augmentation for the Wetzel Pit site in case no. <br />2002CW205. Lafarge is required to operate the Port of Entry Pit site and the Wetzel Pit <br />site under an SWSP until such time as a decree is entered in case nos. 2004CW111 and <br />2002CW205. If reclamation of the mines at the Three Bells Pit, Kyger Pit, and Greeley <br />35`h Avenue Pit sites produces a permanent water surface exposing groundwater to <br />evaporation, an application for a plan for augmentation must be filed with the Division 1 <br />Water Court at least three years prior to the completion of mining to include, but not be <br />limited to, long-term evaporation losses. If a lined pond results after reclamation, <br />
