Joanna Williams March 12, 2018 Page 7 per mile during the April through September irrigation season and 0.25% per mile during the October through March non-irrigation season. Therefore, the transit loss on the Aurora lease water deliveries is projected to be 12.5% during the irrigation season and 6.25% during the non- irrigation season. The lease delivery schedule is shown in Table 3, column 2, and the associated transit loss is shown in column 3. OPERATION OF PLAN In March 2017, RMCC received approval from the Colorado Division of Reclamation, Mining, and Safety to combine the Morton and Holton Lakes mine permits under Permit No. M-2008- 082, AMO1. RMCC has posted an irrevocable letter of credit for $4,150,000 with the Division of Reclamation and Mining Safety to secure the required reclamation of the combined Morton and Holton Lakes Mine Site. Table 3 gives the projected monthly depletions and replacement supplies. As shown in column 4, the SWSP operations proposed herein are projected to result in a surplus of 9.6 ac-ft to the river. The City of Aurora lease water will provide the replacement supplies to cover the projected mining depletions, as shown in Table 3, column 2. The maximum projected transit loss associated with the City of Aurora lease water is shown in Table 3, column 3. Actual transit loss will be assessed based upon the District 2 transit loss rate and the actual location of the City of Aurora lease water deliveries. Based upon the conservative assumptions presented herein, the operation of this SWSP will likely result in a net surplus to the river every month. Individual well permits have already been obtained for Stages 1, 2, 3, 6A, 613, 3 and 4 within the Morton-Holton Lakes Mine. RMCC is concurrently submitting a well permit application to conjoin mine areas located west of the South Platte River; Permit 80046-F for Stage 3 and Permit 811558-F for Stage 4 will be maintained, while Permits 80045-F, 80374-F and 80826-F will be conjoined in a new permit that will include additional mine areas (i.e., Stages 5, 6C, 6D, 6E, and 7). The well permit application will request that the surface areas of all of the stages on the west side of the river be allowed to vary by mining stage boundary so long as all evaporative depletions and fill volumes are replaced under a valid SWSP or permanent augmentation plan. The purpose of the well permit application is to hopefully limit the necessity of obtaining a new well permit for each individual stage or anytime the surface area in a stage changes. We are not requesting that Stages 3 and 4 be included in that well permit application because Stage 3 will be completely backfilled in the near future and Stage 4 is lined and not expected to store any additional water above its currently permitted surface area of 1 acre. To prevent injury to other vested water rights, RMCC proposes to operate the SWSP for the Morton-Holton Lakes Mine from March 1, 2018 through December 31, 2018 under the following terms and conditions: � I
