Ms. Sira Sartori January 4, 2010 Page 4 6. Approval of this plan is for the purposes as stated herein. Any additional uses of this water must first be approved by this office. Any future additional historic consumptive use credit given (e.g., agricultural water transfer) for this site must consider all previous credits given. 7. All pumping for dust control shall be measured in a manner acceptable to the division engineer. 8. All releases of replacement water must be sufficient to cover all out of priority depletions and be made under the direction and/or approval of the water commissioner. The replacement may be aggregated to maximize beneficial use. The water commissioner and/or division engineer shall determine the rate and timing of an aggregated release. 9. The applicant shall maintain daily records of all diversions, replacements, and the amount of water used for each particular purpose. The applicant shall provide a report of these records to the division engineer and the water commissioners on a monthly basis on a form approved by them. The accounting must be submitted within thirty (30) calendar days of the end of the month for which the accounting is being made. In addition, the applicant shall submit a report from each entity making replacements using fully consumable effluent; for this plan, that entity is the City of Fort Lupton. The report shall include an accounting of all wastewater plant water effluent controlled by each entity, showing the total volume of water under its control at the various wastewater treatment plants, and the amount committed to each of the recipients of the water. 10. The replacement water, which is the subject of this plan cannot be sold or leased to any other entity. As a condition of subsequent renewals of this substitute water supply plan, the replacement water must be appurtenant to this site until a plan for augmentation is obtained. A copy of this approval letter should be recorded with the county clerk and recorder. All replacement water must be concurrent with depletions in quantity, timing, and locations. 11. The Applicant shall perform an inspection and provide verification for all parcels of dried up land used to generate: augmentation credits during the term of this SWSP. The final verification of dry up will be in the form of an affidavit signed by an individual having personal knowledge of the dry up for the entire irrigation season for each parcel of land used in this SWSP. The Applicant shall provide all affidavit(s) to the division engineer by November 15, 2011 in order that the final determination of augmentation credits for the irrigation season can be made along with mapping showing any revisions to the dry up acreage. The Applicant shall modify accounting to reflect that the credit from any dried-up fields containing alfalfa or native grass was assessed in the following manner: (a) For fields deep tilled or chemically treated to successfully kill alfalfa or native grass, 100% credit will be given for consumptive use as otherwise computed under the conditions of this approval. (b) For fields not deep tilled or chemically treated to successfully kill alfalfa or native grass, records of monthly monitoring of depth to ground water at existing irrigation wells or existing or new monitoring wells or piezometers within %-mile of each alfalfa or native grass field must be maintained. Credits will be reduced according to the following table when depth to ground water is less than the depth assumed to provide no significant contribution to native grass or alfalfa growth. Measurements taken at the start of each month will determine the necessary reduction in credit to be applied during the following month. The applicant may use another methodology upon review and approval by the State Engineer and Division Engineer.
