Nelson Mining Resource SWSP November 12, 2013 Page 5 of 6 to the abandonment of the Pit. Future SWSPs for this site will not authorize any additional use of ground water until the Applicant provides documentation that a bond sufficient to cover lining or backfilling of the pit has been obtained. 13. The Applicant shall perform an inspection 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 the entire irrigation season for each parcel of land used in this SWSP. In accordance with the attached protocol for dry-up of irrigated land, the Applicant shall provide a written notification to the water commissioner and division engineer by April 1, 2014 identifying the lands to be dried up for the 2014 irrigation season. By October 15, 2014 the Applicant shall provide an affidavit to the water commissioner and division engineer that identifies and confirms the lands that were dried up during the 2014 irrigation season in order that the final determination of augmentation credits for the irrigation season can be made along with mapping showing any revisions to the dried -up acreage. A GIS shapefile must be emailed to Div1Accounting(a-),state.co.us for each dry-up notification and affidavit. The shapefile shall include the pending case number, the WDID of the plan, the acreage of dry-up, and any accompanying metadata. In addition, the datum must NAD83 and the UTM projection must be Zone 13 North. 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. (b) For fields not deep tilled or chemically treated to successfully kill alfalfa, records of monthly monitoring of depth to groundwater at existing irrigation wells or existing or new monitoring wells or piezometers'within' /4 -mile of each alfalfa or native grass field must be maintained. Credits will be reduced according to the following table when depth to groundwater is less than the depth assumed to provide no significant contribution to alfalfa growth. Measurements taken at the start of each month will determine the necessary reduction in credit to be applied during the following month. The applicant may use another methodo ogy upon review and ap roval by the State Engineer and Division Engineer.
