Angela Aldred, P.E. May 21, 2012 CONDITIONS OF APPROVAL Page 3 This substitute water supply plan 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 through March 31, 2013, unless otherwise revoked or modified. 2. Active mining of the site shall not exceed 50 acres unless an amendment to this plan has been approved. 3. 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 5.5 acres including all ponds, collection areas, dewatering trenches, and return trenches. 4. If the actual water surface exposure exceeds 5.5 acres, the additional evaporative depletion must be accounted for and replaced via an amendment to this plan. Documentation of the water surface area, in the form of an aerial photo evaluation or survey by a Professional Land Surveyor, must be submitted to both the Division Office and State Engineer's Office prior to June 1, 2012. 5. The consumption associated with this mining operation is limited to evaporation, dust suppression, and water lost in product not to exceed a total of 30.24 acre -feet in lagged depletions during the 2012 plan year. All diversions for dust suppression must be metered in compliance with the "Amended Rules Governing the Measurement of Tributary Ground Water Diversions Located in the Arkansas River Basin." A totalizing flow meter must be installed and certified for accuracy by a state approved well tester no later than June 30, 2012. 6. AGUA/Fremont Paving 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, 2013) that are caused by diversions of groundwater during the life of the Plan. To guarantee that sufficient augmentation water will be provided to replace such depletions, AGUA has committed an additional 8.7 acre -feet beyond the 30.3 acre -feet required to cover depletions during the 2012 plan year, for a total of 39 acre -feet in the 2 -year lease with Fremont Paving. The 2 -year water lease between AGUA and Fremont Paving was not included with the submittal; therefore, a copy of the lease must be provided to both the Division Office and the State Engineer's Office prior to June 4, 2012. 7. Releases of water by AGUA pursuant to this plan shall be coordinated with the Division Engineer and the Augmentation Coordinator and shall equal or exceed the depletions to be replaced on a monthly basis. 8. Accounting of water in this plan, including excavated area, area of actual ground water exposure, pumping, stream depletions, and replacement water deliveries must be provided to the Water Commissioner (Peter. Kasper(@state.co.us) and Division Engineer ( Div2Ground.WaterCaD-state.co.us) on forms and at times acceptable to them. Said accounting must be received by the 10"' of the month following the month being reported. The name, mailing address, and phone number of the contact person who is responsible for operation and accounting of this plan must be provided on the accounting forms. Repeated attempts to correct issues with your reporting form have yet to be addressed. New accounting form with proper units for each column and accurate water surface area measurement must be implemented immediately.
