Mary R. Halstead, P.E. September 23, 2008 Page 3 of 5 feet (3.25 acre-feet of evaporative depletions and 0.15 acre-feet of mining depletions). Jackson Lake Reservoir is located 30 miles upstream of Chartier Pit; therefore transit losses of 0.5% per mile were included in the depletion calculation. CDOW is proposing an aggregate release of the Jackson Lake Reservoir water during the irrigation season to replace irrigation season depletions. The release of replacement water from Jackson Lake Reservoir may be aggregated to maximize beneficial use; however, the rate and timing of an aggregated release shall be determined by the water commissioner and/or division engineer. The winter season depletions were estimated at 3.55 acre-feet. Replacement of depletions for the.2008-2009 non-irrigation season will be made by a one-year lease with the Fort Morgan Water Company, LTD ("Fort Morgan") using recharge accretion credits attributable to the Fort Morgan Reservoir and Irrigation Company augmentation plan decreed in case no. W-2692. Accretions generated by Fort Morgan are assumed to accrue to the South Platte River in the Brush area. A copy of the Fort Morgan lease was provided to this office on July 7, 2008 and is attached to this letter. CDOW is also proposing an aggregate release of all winter season replacements in January and/or February 2009, to maximize beneficial use; however the rate and timing of an aggregated release shall be determined by the water commissioner and/or division engineer. Conditions of Approval This SWSP is hereby approved pursuant to C.R.S. § 37-92-308(4), subject to the conditions stated below: 1. This SWSP shall be valid for the period of July 7, 2008 through June 30, 2009, unless otherwise revoked, modified, or superseded by decree. Additional SWSPs are required until a court decreed plan for augmentation is obtained for the proposed uses. Should an additional SWSP be requested, the provisions of C.R.S. § 37-92-308(4)(b) shall apply. The statutory fee of $300 will be required pursuant to C.R.S. § 37-92-308(8). Any request for an additional SWSP must be submitted to this office no later than February 28, 2009. 2. Approval of this SWSP is for the purposes stated herein and depletions are limited to the structures identified in case no. 2006CW229. Additional structures and/or additional uses for the water that is the subject of this SWSP will be allowed only if a new SWSP is approved for those additional wellsluses and such additional wells/uses are identified in case no. 2006CW229. Should a new SWSP be requested, the provisions of C.R.S. § 37- 92-308(4)(6) shall apply. The statutory fee of $300 will be required pursuant to C.R.S. § 37- 92-308(8). 3. Well permit no. 58561-F was issued for a maximum of 5.4 acres of exposed pond surface area; however 6.2 acres are reported to be currently exposed. The Applicant is therefore required to obtain a new well permit for the Chartier Pit in accordance with C.R.S. § 37-90-137(2) and this SWSP for the exposed surface area of the pond and product moisture loss from the mined material. A new application is required to be submitted within 60 days of the approval date of this SWSP. The provisions of C.R.S. § 37-90- 137(2) prohibit the issuance of a permit for a well to be located within 600 feet of any existing well, unless the State Engineer finds that circumstances so warrant after a hearing held in accordance with the procedural rules in 2CCR402-5. This hearing may be waived if you are able to obtain statements from the owners of all wells within 600 feet, verifying that they have no objection to your use of the proposed well.
