Holcim South Platte Combined SWSP June 18, 2024 Plan IDs 3614, 4773, 3624, 4772, 4616, 3437, 3376, 3650, 3668, 5475, 5829, i± 6243 Page 23 of 26 20. The Applicant shall perform an inspection of the dried up parcels, submit a Dry-Up Report - Verified Statement of that inspection, and provide a zipped GIS shapefile of the dried-up land as follows: • The Applicant's inspection of dry-up must be submitted on the Dry-Up Report - Verified Statement form by June 30, 2024 indicating planned dry-up and then again in the fall after the irrigation season confirming the planned dry-up was accomplished. A pdf map of each parcel shall be attached to that report. The Dry-Up Report - Verified Statement form is available for download from the Division of Water Resources' website at: https://drive.eooete.com/drive/folders/1TFOatNt6f5ftaOXz n1 iAGCe4xusRN2 (Water Administration Documents / South Platte River Basin Forms). The Dry-Up Report - Verified Statement must be signed by an individual with personal knowledge of the dry-up for the entire irrigation season for each parcel of land associated with the change of water right in this SWSP. The Dry-up Report - Verified Statement submitted on May 5, 2023 included inaccurate information regarding the CAMAS parcel and must be revised. The revised Dry-Up Report - Verified Statement must also include photos taken during a site visit. These revisions were approved in on June 30, 2023. • GIS shapefiles in a file format *.zip outlining the dry-up shall also be submitted at the same time as the Dry-Up Report. The GIS files must include any accompanying attribute data and the datum must be NAD83 and the UTM projection must be Zone 13N. • Submittals shall be made by May 31, 2024 for planned dry-up and by October 31, 2024 for dry-up confirmation. Submittals shall be made through the CDSS Online Reporting Tool (https://dwr.state.co.us/Portal/?ReturnUrt=/Tools/Reporting). Instructions for using the tool are available under Services / Data and Information in the Online Data Submittal Section. Two new Reporting Submittal Tool elements will be created for this SWSP: (1) Dry-up shapefile and (2) Dry-up Report - Verified Statement. For additional assistance, with Online Reporting Submittals, contact Dawn Ewing in the Division 1 office at dnr div1accountine@state.co.us. 21. The historical consumptive use attributed to the changed surface water right(s) under this SWSP shall not include groundwater contributions. As a result, the historical consumptive use ("HCU") credit calculated for the subject water right(s) to be changed by this SWSP shall be reduced by any ongoing sub-irrigation from groundwater. In order to ensure the required dry-up conditions exist during the approval period of this SWSP, and to ensure no sub-irrigation from groundwater is occurring, the Applicant shall provide records of monthly monitoring of depth to groundwater for all land associated with the change of water right(s) in this SWSP. Information regarding depth to groundwater may be provided using existing irrigation wells, existing or new monitoring wells, or piezometers located on the dried-up fields. The Applicant may utilize wells or piezometers located within 1/4 mile of each field provided that the Applicant can demonstrate the depth to groundwater information available off-site is representative of the depth to groundwater on the dried-up land. The Applicant shall modify its accounting to reduce the amount of the calculated HCU that may be claimed in this SWSP according to the table below. 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 methodology upon review and prior approval by the state engineer and division engineer. (Construction of monitoring holes/wells, or piezometers
