Mr. Stephen Buechner, P.E. December 8, 2016 <br /> Page 4 of 6 <br /> July 3, 2017. <br /> 2. Well permit no. 78822-F was obtained for the current use and exposed pond surface area of <br /> the gravel pit in accordance with 537-90-137(2) and (11), C.R.S. <br /> 3. The total surface area of the groundwater exposed at the Parkdale Project site must not <br /> exceed those amounts listed in Column 2 of Table 1. The net annual evaporative loss must not <br /> exceed 13.19 acre-feet during this SWSP period. <br /> 4. The annual amount of water used at the operation shall not exceed 8.8 acre-feet for dust <br /> control and the total product mined shall not exceed 540,700 tons (387,500 tons of washed <br /> aggregate and 153,200 tons of unwashed material) resulting in 13.66 acre-feet of water lost <br /> with the product. <br /> 5. Total consumption at the Parkdale Project site must not exceed the aforementioned <br /> amounts unless a new SWSP is obtained. <br /> 6. Water used for gravel washing ponds that does not infiltrate within 24 hours may require a <br /> new SWSP to include additional acres of exposed surface area subject to evaporation that <br /> will require additional replacement under the plan. Field visits by the Water Commissioner <br /> will be made to confirm that 3.4 acres of evaporative surface area is appropriate for settling <br /> ponds and the gravel washing pond under this plan. <br /> 7. Approval of this plan is for the purposes as stated herein. Any additional uses of this water <br /> must first be approved by this office. <br /> 8. All pumping for product washing and dust control Shall be measured in compliance with the <br /> Amended Rules Governing the Measurement of Tributary Ground Water Diversions Located in <br /> the Arkansas River Basin. <br /> 9. The Applicant shall provide daily accounting (including, but not limited to diversions, <br /> depletions, replacement sources, and river calls) on a monthly basis. The accounting must <br /> be emailed to the Division Engineer (augmentation.coordinator@state.co.us) and the Water <br /> Commissioner (Joshua.Kasper®state.co.us) with the subject line "Parkdale Project Gravel <br /> Pit SWSP". Said accounting must be received by the W of the month following the month <br /> being reported. The name, mailing address, and phone number of the contact person who is <br /> responsible for operation and accounting of this plan must be provided on the accounting <br /> forms. <br /> 10.Approval of this SWSP does not relieve the Applicant and/or the landowner of the <br /> requirement to obtain a Water Court decree approving a permanent plan for augmentation <br /> or mitigation to ensure the permanent replacement of all depletions, including long-term <br /> evaporation losses and tagged depletions after gravel mining operations have ceased. If <br /> reclamation of the mine site will produce a permanent water surface exposing groundwater <br /> to evaporation, an application for a plan for augmentation must be filed with the Division 2 <br /> Water Court at least three (3) years prior to the completion of mining, to include, but not <br /> be limited to, long-term evaporation losses and lagged depletions. If a lined pond results <br /> after reclamation, replacement of lagged depletions from mining and dewatering shall <br /> continue until there is no longer an effect on stream flow. <br /> %F�coy <br /> Office of the State Engineer <br /> ` 9 ie <br /> 1313 Sherman Street,Room 821,Denver,CO 80203 P 303.866.3581 yf <br /> www.water.state.coms *�, ( <br />
