Ready Mix Concrete Substitute Water Supply Plan Page 7 of 9 November 24, 2020 3. The total surface area of the groundwater exposed at the Morton-Holton Lakes site must not exceed 17.5 acres in October 2020, 18.3 acres for November through December 2020, and 23 acres for 2021. The surface area must not exceed 11 acres for Stage 1 for this SWSP period; 5 acres for October through December 2020 and 10 acres for 2021 for Stage 2; 0.2 acres for Stage 4 for this SWSP period; 0.2 acres for October 2020 and 1 acre for 2021 for Stage 5; 0.5 acres for October through December 2020 and 0.2 acres for 2021 for Stage 613; and 0.5 acres for Stage 6C/6D for this SWSP period. Should the total surface area exposed exceed those amounts, an amendment request shall be promptly filed with this office. 4. The water used for dust control at the Morton-Holton Lakes site shall not exceed 18.8 acre-feet and the total product mined at the Morton-Holton Lakes shall not exceed 1,873,300 tons, which results in 29.8 acre-feet of water lost from washing and mined product. The total amount associated with the additional fill of Stage 2 shall not exceed 75 acre-feet and the total amount used for Stage 4 reservoir construction shall not exceed 61.6 acre-feet. 5. Total consumption at the Morton-Holton Lakes site must not exceed these aforementioned amounts unless an amendment is made to this SWSP. 6. Approval of this SWSP is for the purposes as stated herein. This office must first approve any additional uses for the water. 7. All pumping for dust control shall be measured in a manner acceptable to the Division Engineer. 8. The replacement water that is the subject of this SWSP cannot be sold or leased to any other entity. As a condition of subsequent renewals of this SWSP, the replacement water must be appurtenant to this site until a plan for augmentation is obtained. All replacement water must be concurrent with depletions in quantity, timing, and locations. 9. Adequate accounting of depletions and replacements must be provided to the Division Engineer in Greeley (Div1AccountingCstate.co.us) and the Water Commissioners (Jorge Vidal at Jorge.Vidat@state.co.us and Brent Schantz at Brent.SchantzCstate.co.us) on a monthly basis. All amounts shall be in acre-feet. All submitted accounting must conform to the Administration Protocol "Augmentation Plan Accounting- Division One, South Platte River" (attached). In addition, the Applicant shall verify that the entity making replacements has included the Applicant on their accounting and submitted their accounting to the division office and the Water Commissioner; for this SWSP, that entity is the City of Aurora. 10. Conveyance loss for delivery of augmentation water to the point of depletion on the South Platte River is subject to assessment and modification as determined by the Division Engineer. 11. The Division Engineer, or their 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.
