Ms. Angela Aldred November 25, 2015 Page 3 of 5 agreed to provide 2.90 acre-feet of fully consumable recharge credits from its Excelsior Recharge Ponds during the period of April 2016 through March 2017 if needed." The State and Division Engineers have reviewed the plan and the adequacy of each source of water provided for use as augmentation water, including, where necessary, the historical consumptive use of each water right, and return flows from diversion of waters imported into the Arkansas River Basin or other fully consumable waters proposed for use as augmentation water. CONDITIONS OF APPROVAL This SWSP is hereby approved pursuant to Section 37-90-137(11), C.R.S., subject to the following conditions: 1. This current plan shall be valid April 1, 2015 through March 31, 2016, unless otherwise revoked or modified.

In accordance with the letter dated April 30, 2010 from the DRMS and as requested herein, explanation and/or documentation must be provided with the next SWSP renewal request which demonstrates that a financial warranty sufficient to cover the cost of installing a clay liner or slurry wall that meets the Division of Water Resources requirements for preventing ground water exposure has been filed specifically for Phase (- Parcel 4 of the mine site. 3. As requested herein, explanation and/or documentation must be provided the next SWSP renewal request for the distance to stream and the distance to no -flow boundary parameters utilized in the Glover lagging analysis. 4. Active mining or dust control shall not occur at the site under this SWSP. Should the operator desire to resume mining or provide water for dust control at the site, a new SWSP must be obtained. 5. The mined cell must be maintained in a de -watered state to the extent that the exposed water surface area does not exceed a total of 3.5 acres including all ponds, collection areas, dewatering trenches, and return trenches. If the actual water surface exposure exceeds 3.5 acres, the additional evaporative depletion must be accounted for and replaced under a new SWSP obtained by the Applicant. 6. The consumption associated with this mining operation is limited to evaporation not to exceed a total of 9.18 acre-feet in lagged depletions during the 2015 - 2016 plan year. 7. AGUA/Stonewall Springs agree to replace out -of -priority depletions to senior surface water rights in Colorado and depletions to usable Stateline flows occurring after the expiration date of the plan (March 31, 2016) that are caused by diversions of ground water during the 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 F 303.866.3589 www.water.state.co.us 1
