d2 CAD Consulting,LLC <br /> CCWRE <br /> EXHIBIT G <br /> WATER INFORMATION <br /> Local surface water features are shown on Exhibit B, Index Map, Exhibit C-2,Pre-Mining Map and Exhibit <br /> F-1, Reclamation Plan Map. The Big Thompson River runs along the eastern edge of the permit <br /> boundary. The Hillsborough Ditch runs approximately 1,200 feet south of the site. <br /> Final discharge of excess water recovered and clarified from de-watering of Cell 4 is discharged to the <br /> Big Thompson River via the settling pond adjacent to the river. This discharge will stop upon completion <br /> of mining of Cell 4. This discharge is permitted through Colorado Department of Public Health and <br /> Environment,Water Quality Control Division: Permit No. COG501572. A copy of this permit is included <br /> with Exhibit M. <br /> Mining Cells 1, 2, and 3 have created groundwater fed ponds with a total of 12.2 acres of current <br /> exposed water surface as shown in the table below. Cell 4 is currently being mined and dewatered. A <br /> total of 30.5 acres of exposed water surface is allowed under Well Permit Number 67817. Conditions 5 <br /> and 6 allow for use of up to 105.28 acre-ft of ground water: the use of ground water in addition to <br /> dewatering is limited to 76.86 acre-feet (ac-ft) of evaporative loss, 2.95 ac-ft of water lost with mined <br /> product, 7.06 ac-ft of water used for dust suppression, and 18.41 ac-ft used in concrete production. A <br /> copy of Well Permit 67817 is included with Exhibit M. <br /> At final reclamation,consumptive use of water will continue through dust suppression in the plant area <br /> and on internal haul roads,through evaporative loss from the remaining exposed mining cells,as well as <br /> water used for concrete production and material processing. All of these consumptive uses have been <br /> augmented in Water Court Case 2009CW105. A copy of 2009CW105 has been included with Exhibit M. <br /> 2009CW105 Section 35.1 allows for 25.5 acre-ft of water for mining and production, and Section 35.2 <br /> allows for 166 acre-ft of evaporative loss from exposed water surfaces,with total exposed surface area <br /> of 65 acres. <br /> At the time of final reclamation, it is anticipated the exposed surface areas of the final pond <br /> configurations will be as follows: <br /> TABLE G - POND FINAL WATER SURFACE AREAS <br /> Pond Designation Exposed Water Surface Area(acres) <br /> Cell 1 3.02 <br /> Cell 2 2+/-(currently being filled) <br /> Cell 3 5.7 <br /> Cell 4 31.79(ultimate) <br /> Farm Pond 4.0 <br /> Total 46.6 <br /> There is one monitoring well within the permit boundary and two monitoring wells located south of the <br /> permit area. The location of the wells is shown on Exhibit C-1. A copy of the well readings is included <br /> with this Exhibit. Well readings are taken quarterly, and there will be no change with the revised <br /> reclamation plan. <br /> APPLICATION FOR AMENDMENT TO LOVELAND READY MIX CONCRETE,INC <br /> REGULAR 112 PERMIT NO.M-2001-022 GREEN/CROISSANT SAND AND GRAVEL MINE <br /> August,2016 12 OF 39 <br />
