Mr. Andy Rodriguez, P.E. Page 3 of 6 <br /> Bestway's Brighton Combined SWSP <br /> February 10, 2016 <br /> Allowable AF Amount 43.5 AF <br /> Maximum Pumping Rate 100 gpm <br /> The well is currently permitted for industrial, commercial and augmentation use. The <br /> Applicant's accounting includes the 2% relinquishment requirement for the nontributary <br /> Laramie-Fox Hills water. <br /> The applicant has entered into a long term lease agreement with the City of Aurora <br /> ("Aurora") whereby Aurora will deliver up to 49 acre-feet of fully consumable water to the <br /> South Platte River at the confluence of the South Platte River Et Sand Creek, just north of <br /> Metro Wastewater Treatment Plant. The confluence is located approximately 20 miles <br /> upstream of the Baseline Resource site. A 0.25 percent per mile transit loss for November <br /> through March (5.0 percent overall loss) and a 0.5 percent per mile transit loss for April <br /> through October (10.0 percent overall loss) has been accounted for in the replacement <br /> schedule. The transit loss is subject to change depending upon current conditions. If transit <br /> losses will change they will be communicated by the Division Engineer via email to the <br /> Division One Call List. <br /> In addition to replacing depletions resulting from this mining operation, the City of <br /> Aurora effluent will also be used by the Applicant to replace 21.65 acre-feet of depletions <br /> resulting from operation of the Bestway Concrete Well No. 1 (aka the Litvak Well, permit no. <br /> 67418-F, WDID 0210164), in accordance with the Bestway Concrete Augmentation plan (water <br /> court case no. 2004CW224). Since the City of Aurora effluent is being used as a replacement <br /> source for this SWSP and the Litvak Well (case no. 2004CW224), the applicant's accounting for <br /> this SWSP and case no. 2004CW224 must specify the total amount of effluent released and the <br /> amount associated with this SWSP and the court case. <br /> A monthly breakdown of depletions and replacements, including the Litvak obligations, is <br /> shown on the attached Table 3. <br /> Conditions of Approval <br /> I approve the proposed substitute water supply plan in accordance with Section 37-90- <br /> 137(11), C.R.S., subject to the following conditions: <br /> 1. This SWSP shall be valid for the period of January 1, 2016 through December 31, 2016, <br /> unless otherwise revoked, modified, or superceded by decree. If this plan will not be <br /> made absolute by a water court action by the plan's expiration date, a renewal <br /> request must be submitted to this office with the statutory fee (currently $257) by <br /> November 1, 2016. <br /> 2. Well permit no. 67585-F was obtained for the current use and exposed pond surface <br /> area of the Parker-Dersham Pit, and well permit no. 66959-F was obtained for the <br /> current use and exposed pond surface area of the Baseline Pit in accordance with 537- <br /> 90-137(2) and (11), C.R.S. The Applicant is required to maintain a valid well permit for <br /> the current uses at each site. <br /> 3. Well permit no. 75087-F was obtained for dust suppression and concrete batching <br /> purposes approved under this SWSP and must remain valid for the duration of this <br /> SWSP. <br /> 4. The total surface area of the groundwater exposed at Parker-Dersham Pit site must not <br /> exceed 6.5 acres during the approval period of this SWSP resulting in an annual <br /> evaporative loss of 19.15 acre-feet. <br />
