Mr. Peter Foster, P.E. August 29, 2014 Page 5 8. All diversions shall be measured in a manner acceptable to the division engineer. The Applicant shall install adequate measuring devices as required by the division engineer for the operation of this plan. 9. All deliveries of replacement water shall be measured in a manner acceptable to the division engineer. 10. All pumping for dust control shall be measured in a manner acceptable to the division engineer. 11. The approval of this substitute water supply plan does not relieve the Applicant and /or the landowner of the requirement to obtain a Water Court decree approving a permanent plan for augmentation or mitigation to ensure the permanent replacement of all depletions, including long -term evaporation losses and lagged depletions after gravel mining operations have ceased. If reclamation of the mine site will produce a permanent water surface exposing groundwater to evaporation, at least three years prior to the completion of the mine an application for a plan for augmentation must be filed with the Division 4 Water Court, to include, but not be limited to, long -term evaporation losses and lagged depletions. If a lined pond results after reclamation, replacement of lagged depletions from mining and dewatering shall continue until there is no longer an effect on stream flow. 12. Dewatering at this site will produce delayed depletions to the stream system. As long as the pit is continuously dewatered, the water returned to the stream system should be adequate to offset the depletions attributable to the dewatering operation. Once dewatering at the site ceases, the delayed depletions must be addressed. Accordingly, dewatering is required to continue during the term of this approval. At least three years prior to completion of dewatering, a plan must be submitted that specifies how the post pumping dewatering depletions (including refilling of the pit) will be replaced in time, place and amount. 13. The Applicant shall perform inspections and provide verification for all parcels of dried up land used to generate augmentation credits during the term of this SWSP. The final verification of dry up will be in the form of an affidavit signed by an individual having personal knowledge of the dry up for each entire irrigation season for each parcel of land used in this SWSP. By October 31, 2014, and again by October 31, 2015, the Applicant shall provide an affidavit to the water commissioner and division engineer that identifies and confirms any lands that were dried up during the 2014 and 2015 irrigation seasons in order that the final determination of augmentation credits for the irrigation seasons can be made, along with mapping showing any revisions to the dried -up acreage. The Applicant shall provide written notifications to the water commissioner and division engineer by September 15, 2014, identifying any lands dried up for the 2014 irrigation season, and by April 1, 2015, identifying any lands to be dried up for the 2015 irrigation season. The Applicant shall modify accounting to reflect that the credit from any dried up fields containing alfalfa or native grass was assessed in the following manner: (a) For fields deep tilled or chemically treated to successfully kill alfalfa or native grass, 100% credit will be given for consumptive use as otherwise computed under the conditions of this approval.
