Aggregate Industries South Platte Combined SWSP January 30, 2019 Plan IDs 3614, 4773, 3624, 4772, 4616, 3437, 3376, 3650, 3668, and 5475 Page 18 of 21 13.The Division Engineer, or his designated representative, will administer all such water transported in the South Platte River or its tributaries under this SWSP, including water for replacement of depletions, past intervening headgates to ensure that such water is not intercepted or otherwise diminished in quantity by diversion, use or other interference by intervening water rights and to assure that such water remains available and suitable for Applicant’s uses under this SWSP, except when any intervening headgate is diverting the entire flow of (“sweeping”) the river. In the event that delivery past headgates which sweep the river requires the installation of a bypass structure or the use of an existing bypass structure by agreement with a third-party, Applicant is responsible for either installing a new bypass structure with a continuous recording measuring device(s) as approved by the Water Commissioner or securing an agreement with a third-party to use an existing bypass structure and providing such information and agreement to the Division Engineer. 14.The Division of Water Resources will not be responsible for any enforcement or administration of third party agreements that are not included in a decree of the water court. 15.The name, address, and phone number of a contact person who will be responsible for the operation and accounting of this plan must be provided to the Water Commissioner(s) and the Division Engineer. 16.Subject to prior approval by the division engineer, the Applicant may lease or purchase additional replacement water as identified in this SWSP request. Such additional sources of replacement water may only be used in this SWSP if the Applicant complies with the attached Division One Administration Protocol “Use of Replacement Sources Not Specifically Identified in an SWSP or Augmentation Plan”. 17.The Applicant shall perform an inspection and provide verification that the land associated with the changed water rights in this SWSP has been removed from irrigation during the term of this SWSP. Verification of dry-up must be in the form of an affidavit signed by an individual with personal knowledge of the dry-up for the entire irrigation season for each parcel of land associated with each change of water right in this SWSP. In accordance with the attached “Administration Protocol - Dry-Up of Irrigated Land”, by October 31, 2019, the Applicant shall provide an affidavit to the water commissioner and division engineer that confirms dry-up during the 2019 irrigation season. A GIS shapefile outlining the dry-up must accompany each affidavit and be emailed to DNR_Div1Accounting@state.co.us. The shapefile shall include the pending court case number, the WDID of the plan, a delineation of the dried-up land, the acreage of dry-up, and any accompanying metadata. In addition, the datum must be NAD83 and the UTM projection must be Zone 13. If a shapefile of the acreage was provided previously and the proposed dry-up acreage has remained the same, the notice can reference the previously provided shapefile, rather than providing it again. If the actual dry-up does not match the land proposed for dry-up in the spring, a revised GIS shape file must be submitted with the affidavit in the fall. 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)
