Ewing Gravel Mine Substitute Water Supply Plan Page 5 of 7 <br /> March 25, 2024 <br /> 4. Computation of evaporation under this SWSP was reduced during the ice-covered period. <br /> However, for the purpose of this SWSP, the Applicant shall replace the net evaporative depletions <br /> from the exposed groundwater surface area that occurred during the assumed ice-covered period <br /> (the months of December and January) for any time that the pit is not completely covered by ice. <br /> 5. The total amount of water consumed from water lost with mined product must not exceed 48.2 <br /> acre-feet. The total amount of water used for dust control at the site must not exceed 4.8 <br /> acre-feet and the total amount of water used for slurry wall construction at the site must not <br /> exceed 10.5 acre-feet. The total water pumped for dewatering must not exceed 2,025 acre-feet. <br /> All pumping for these uses must be metered and tracked by the operator, and be included on <br /> submitted accounting. <br /> 6. Total consumption at the site must not exceed the aforementioned amounts unless an amendment <br /> is made to this SWSP. <br /> 7. Approval of this SWSP is for the purposes as stated herein. Any additional uses of this water must <br /> first be approved by this office. <br /> 8. All releases of replacement water must be sufficient to cover all out-of-priority depletions in <br /> time, place, and amount and must be made under the direction and/or the approval of the Water <br /> Commissioner. The release of replacement water may be aggregated to maximize beneficial use, <br /> subject to approval by the Division Engineer or Water Commissioner. The Water Commissioner <br /> and/or the Division Engineer shall determine the rate and timing of an aggregated release. <br /> 9. The Applicant must replace all out-of-priority depletions resulting from operation under this SWSP, <br /> including those lagged depletions that occur to the stream after the expiration date of this SWSP. <br /> 10. The Applicant shall provide daily accounting (including, but not limited to diversions, depletions, <br /> replacement sources, ice cover, and river calls) on a monthly basis. The accounting must be <br /> uploaded to the CDSS Online Reporting Tool within 30 days of the end of the month for which the <br /> accounting applies (https://dwr.state.co.us/Tools/reporting). Instructions for using the tool are <br /> available on the Division of Water Resources website on the "Services" —> "Data St Information" <br /> page under the heading of "Online Data Submittal". Accounting and reporting procedures are <br /> subject to approval and modification by the Division Engineer. Accounting forms need to identify <br /> the WDID number for each structure operating under this SWSP. NOTE: Monthly accounting, even <br /> during the winter non-irrigation season, is required. <br /> In addition, the Applicant shall verify that the City of Aurora (WDID 0602503) includes in their <br /> monthly accounting, a report on the reusable water released to provide replacement for this <br /> SWSP. It is the Applicant's responsibility to ensure the City releases the leased water in the <br /> correct time, place, and amount. <br /> 11. The name, address, and phone number of a contact person who will be responsible for the <br /> operation and accounting of this SWSP must be provided on the accounting forms to the Division <br /> Engineer and Water Commissioner. <br />
