City of Boulder:January 27, 2016. PLAN FOR AliGMENTATION 9. Structures to be Augmented: The Geisert Pit Cell I was created as part of the mining operations on the property and exposes groundwater to the atmosphere. This augmentation plan will replace the evaporative depletions associated with this cell. Geisert Pit Cell 1 is located in the Northeast '/4 of Section 31, Township 6 North, Range 65 West of the 6`h P.M. Weld County, Colorado, with a combined surface area of 8.9 acres. However, 2.3 acres of surface area resulted from pre-1981 mining activities. Therefore, Applicant intends to replace depletions from a surface aria of 6.6 acres. The total exposed surface area will be limited to no more than 8.9 acres. The estimated depletions from Cell 1 to be replaced by Applicant are 19.3 acre feet per year. If at any point, Weld County changes the number of surface acres of exposed groundwater from Cell 1, then their replacement obligation may be correspondingly reduced hereunder upon filing a notice with the Court and the objectors of the fact it has reduced the number of surface acres of exposed groundwater and of the new depletion amount which shall be determined based on the methodology decreed herein based on the number of surface acres still exposed. The Court retains continuing jurisdiction to review any objection to such notice. If any person wishes to object to the proposed reduction in the replacement obligation, that person shall file a written objection with the Court within thirty- five (35)days of receipt of the notice. The Applicant shall have the initial burden of proof to show that the proposed reduction will not injure vested water rights or decreed conditional rights. If no objection is filed, then Weld County may reduce its replacement obligation in the manner stated in the Notice without further action by the Court. If an objection is so filed, the Applicant may not reduce its replacement obligation until the Court determines whether, and under what terms and conditions necessary to prevent injury to vested water rights and decreed conditional rights, the reduction may be made. 10. Method for Determination of Depletions. The Integrated Decision Support Group's Alluvial Water Accounting System model (IDSAWAS), Version 1.5.77, was used to estimate depletions to the Cache la Poudre River associated with the evaporative depletions from the Geisert Pit Cell 1. The calculated amount of water to be replaced is 19.3 acre feet per year distributed monthly as shown below in Table 1. Total evaporative depletions were determined by multiplying the monthly unit evaporation rates in Table 2 below by the acreage of exposed water surface area.
