Mr. Todd Williams Page 3 <br /> G.L. SWSP <br /> June 27, 2014 <br /> depletions that result from mining related exposure of ground water. The DRMS letter identifies <br /> four approaches to satisfy this requirement. In accordance with approach no. 1 and 3, you have <br /> obtained a bond for $116,700 through DRMS which may be used for backfilling the exposed <br /> ground water in the unlikely event that the mining operator abandons the site. <br /> Please note that the approval of this substitute water supply plan does not relieve the <br /> Applicant and/or the landowner of the requirement to obtain a water court decree approving a <br /> permanent plan for augmentation or mitigation to ensure the permanent replacement of all <br /> depletions, including long-term evaporation losses and lagged depletions after gravel mining <br /> has ceased. The Applicant has demonstrated that the backfilling of the site will continue, thus <br /> an augmentation plan with the Division 1 Water Court to cover long-term evaporation losses at <br /> the G. L. Pit site is not required at this time. <br /> Conditions of Approval <br /> I hereby approve the proposed substitute water supply plan in accordance with §37-90- <br /> 137(11), C.R.S., subject to the following conditions: <br /> 1. This plan is approved with the effective date of June 1, 2014 through May 31, 2015 unless <br /> otherwise revoked or modified. If the groundwater pond has not been completely <br /> backfilled and lagged depletions to the stream system have not ceased by the plan's <br /> expiration date, a renewal request must be submitted to this office with the statutory fee <br /> (currently $257) no later than April 15, 2015. <br /> 2. Well permit no. 42334-F was obtained for the current use and exposed pond surface <br /> area of the gravel pit, in accordance with §37-90-137(2) and (11), C.R.S. Applicant shall <br /> operate the gravel pit in accordance with the conditions of approval of permit no. <br /> 42334-F. <br /> 3. The total surface area of exposed groundwater must not exceed 1.16 acres resulting in <br /> 2.91 acre-feet of evaporative loss. Should the total consumption at the pit exceed this <br /> amount, the Applicant is required to file an amendment with this office. <br /> 4. Approval of this plan is for the purpose as stated herein. Any additional uses for which <br /> the water may be used must first be approved by this office. <br /> 5. All releases of replacement water must be sufficient to cover all out-of-priority depletions <br /> in time, place, and amount and must be made under the direction and/or the approval of <br /> the water commissioner. The release of replacement water may be aggregated to <br /> maximize beneficial use. The water commissioner and/or the division engineer shall <br /> determine the rate and timing of an aggregated release. <br /> 6. The replacement water that is the subject of this plan cannot be sold or leased to any <br /> other entity. As a condition of subsequent renewals of this substitute water supply plan, <br /> the replacement water must be appurtenant to this site until the groundwater pond has <br /> been completely backfilled and the lagged depletions to the stream system have ceased. <br /> 7. The name, address, and phone number of the contact person who will be responsible for <br /> the operation and accounting of this plan must be provided on the accounting forms <br /> submitted to the division engineer and the water commissioner. <br /> 8. Adequate accounting of depletions and replacement must be provided to the division <br /> engineer in Greeley (Div1Accountinga-state.co.us) and the water commissioner (Mark <br /> Simpson at Mark.Sim psonastate.co.us) on a monthly basis. Accounting forms are <br /> subject to modification and approval by the division engineer. Submitted accounting shall <br />
