Mr. Andy Rodriguez, P.E. Page 3 of 6 April 18, 2011 resulting from operation of the Bestway Concrete Well No. 1 (permit no. 67418-F), in accordance with the augmentation plan decreed in Division 1 Water Court case no. 2004CW224 (see Table 4). Since the City of Aurora effluent is being used as a replacement source for both SWSPs and the decreed augmentation plan, the applicant's accounting for each SWSP must specify the total amount of effluent released and the amount associated with each SWSP and the decreed plan for augmentation. The nontributary Laramie-Fox Hills aquifer water will be withdrawn by an existing well pursuant to permit no. 64750-F. Additional information regarding the well is shown below: Well Field WDID None Well Field Name None Relevant Water Right Case Number None Well WDID 0210166 Well Name Hall Irwin LFH 64750-F Relevant Well Permit 64750-F Well Location NE% NE% SE% Sec 36, TIN, R67W, 6 P.M. Aquifer Laramie-Fox Hills Allowable AF Amount 43.5 AF Maximum Pumping Rate 100 m The well is currently permitted for industrial, commercial and augmentation use. The Applicant's accounting includes the 2% relinquishment requirement for the nontributary Laramie-Fox Hills water. In addition to replacing depletions resulting from this mining operation, the Laramie-Fox Hills aquifer water will also be used by the Applicant to replace 10.84 acre-feet of depletions resulting from operations at the Parker-Dersham Resource site in accordance with the C.R.S. 37-92-308(11) SWSP approved for Hall-Irwin (see Table 4). Since the Laramie-Fox Hills water is being used as a replacement source for both plans, the applicant's accounting for each SWSP must specify the total amount of Laramie-Fox Hills water released and the amount associated with each SWSP. A monthly breakdown of depletions and replacements is shown in the attached Table 3. Conditions of Approval I approve the proposed substitute water supply plan in accordance with Section 37-90- 137(11), C.R.S., subject to the following conditions: 1. This SWSP shall be valid for the period of January 1, 2011 through December 31, 2011, unless otherwise revoked, modified, or superceded by decree. If this plan will not be made absolute by a water court action by the plan's expiration date, a renewal request must be submitted to this office with the statutory fee (currently $257) by November 15, 2011. 2. Well permit no. 66959-F (WDID 0203017) was obtained for the current use and exposed pond surface area of the gravel pit pond in accordance with §37-90-137(2) and (11), C.R.S.
