Well Location NE%4, NE%4, SE%4, Sec 36, Ti N, R67W, 6"' P.M. Aquifer Laramie -Fox Hills Allowable AF Amount 43.5 AF Maximum Pumping Rate 100 gpm Mr. Andy Rodriguez, P.E. Bestway's Brighton Combined SWSP December 12, 2012 Page 3 of 5 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. The applicant has entered into a long term lease agreement with the City of Aurora ( "Aurora ") whereby Aurora will deliver up to 49 acre -feet of fully consumable water to the South Platte River at the confluence of the South Platte River & Sand Creek, just north of Metro Wastewater Treatment Plant. The confluence is located approximately 20 miles upstream of the Baseline Resource site. A 0.25 percent per mile transit loss for November through March (5.0 percent overall Toss) and a 0.5 percent per mile transit loss for April through October (10.0 percent overall loss) has been accounted for in the replacement schedule. In addition to replacing depletions resulting from this mining operation, the City of Aurora effluent will also be used by the Applicant to replace 21.33 acre -feet of depletions resulting from operation of the Bestway Concrete Well No. 1 (aka the Litvak Well, permit no. 67418 -F, WDID 0210164), in accordance with the Bestway Concrete Augmentation plan (water court case no, 04CW224). Additionally, Bestway has added to this lease 24.49 acre -feet of water for the Shores SWSP (WDID 0502522) for the months of January and February 2013. Since the City of Aurora effluent is being used as a replacement source for multiple plans, the applicant's accounting for each SWSP must specify the total amount of effluent released and the amount associated with each SWSP. A monthly breakdown of depletions and replacements, including the Litvak and Shores obligations, is shown in 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SWSP shall be valid for the period of January 1, 2013 through December 31, 2013, unless otherwise revoked, modified, or superceded by decree.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, 2013. 2. Well permit no. 67585 -F was obtained for the current use and exposed pond surface area of the Parker - Dersham Pit, and well permit no. 66959 -F was obtained for the current use and exposed pond surface area of the Baseline Pit in accordance with §37 -90- 137(2) and (11), C.R.S.

Well permit no. 75087 -F was obtained for dust suppression and concrete batching purposes approved under this SWSP and must remain valid for the duration of this SWSP. 4. The total surface area of the groundwater exposed at this site must not exceed 2 acres at the Baseline Pit and 7.9 acres at the Parker - Dersham Pit during the approval period of this SWSP resulting in an annual evaporative loss of 29.15 acre -feet. 5. The annual amount of water used at the operation shall not exceed 3.24 acre -feet for dust
