6.4.7 EXHIBIT G - Water Information <br /> 4. The last SWSP plan DRMS has on file is from 2007. Is there a more current SWSP?Please <br /> submit a copy of the most recent SWSP. <br /> No, The last SWSP that was needed is the 2007 version since the Riverside Pit is now <br /> covered by the Logan Well Users Association decree and augmentation plan. <br /> 5. Is the current SWSP adequate enough to cover the proposed exposed water in AM3 until the <br /> LWUA permit can be revised? <br /> Yes, The current decree allows for 120 acre feet of evaporation loss from 47.64 ac. <br /> of post 1981 water surface exposed. At this time the total lake surface at the <br /> Riverside Pit is 21.54 ac-ft of which 5.70 acres is pre 1981 water and 15.84 aces is <br /> post 1981 water that requires 39.90 ac-ft. Prior to opening more then 45 acres of <br /> post 1981 lake area, LWUA will be asked to add more water to the Augmentation Plan <br /> to cover the evaporative losses from the final lake sizes. <br /> 6.4.19 EXHIBIT S- Permanent Man-made Structures <br /> 7. Currently, about 850 feet of the Lowline Ditch will border the East Lake within 100 feet. In <br /> this amendment, an additional 925 feet of Lowline Ditch will border Lake Marjorie. On page 9 it <br /> states that the armoring on the east shore of the East Lake will not be extended into Lake <br /> Marjorie to protect the ditch. The reason given was that extensive work has been already done to <br /> protect the Lowline Ditch from the effects of river flooding by the ditch company. It is not clear <br /> from the AM3 application if the work completed is also adequate to protect the ditch from the <br /> effects of mining. <br /> When the City of Sterling sold this area to McAtee they retained a 50 foot wide <br /> strip along the west side of the ditch for access and room to do maintenance on the <br /> ditch if needed. McAtee then planned to have a 25 foot wide top of slope setback <br /> from the property line and another 22 feet of dredge setback where vertical mining <br /> will end. This leave a total of leaving 97 plus feet from the armoring on the inside of <br /> the ditch to the active mining limit. <br /> After reviewing the plan McAtee will commit to adding an additional 925 feet of bank <br /> armoring along the east side of the amendment area following the methods approved <br /> in the Bank Protection Plan on Page 2 under the heading titled "East lake Bank <br /> Armoring' dated 8/20/2019. The Reclamation Plan Map has been revised to show <br /> the armoring to be installed from the south point and extending along the east side <br /> Riverside Pit Adequacy Response-June 17,2022(12:1 1pm) Page 3 <br /> Permit#M-1976-056 <br />
