Assuming 4 percent moisture content by weight as suggested by the State Engineer's <br />Office, the total annual depletion due to water retained in product is 8.83 acre-feet. <br />In addition, water use at the site will include dust control. From previous experience, in <br />mining operations similar to this one, a reasonable estimation of 2.0 acre-feet per year <br />was used in determining the total consumptive use of the mining operation. <br />The total annual consumptive uses associated with the mining operations are as follows: <br />Evaporation (acre-feet) 40.39 <br />Moistre Retained in Product (acre-feet) 8.83 <br />Dust Control (acre-reel) 2.00 ~ <br />Total (acre-feet) 51.22 <br />Water Rights <br />Replacement water will be provided under Aggregate Industries' South Platte Combined <br />Replacement Plan which has been accepted and approved by the State Engineer's Office. <br />The plan will be amended to include this site. Sources of water include historic <br />consumptive use credits from the Fulton Ditch, water from the City of Westminster, and <br />other water currently available to Aggregate under lease agreements. Under the <br />Combined Replacement Pian, replacements are made to the South Platte River at various <br />locations including the ivleiro Wastewater Treatment Plant outfall structure located <br />upstream of the property. Transit loss associated with the replacement water sources is <br />assumed to be 0.25% per mile. Sources of water currently available to Aggregate are <br />described as follows: <br />• 0.28 cfs of fully consumable water every day of the year delivered in <br />perpetuity at the confluence of Clear Creek and the South Platte River <br />in Adams County, Colorado. <br />• In addition to the amounts identified in the above paragraph, an <br />additional 0.17 cfs of fully consumable water every day from October <br />2 until June 30 delivered in perpetuity at the confluence of Clear Creek <br />and the South Platte River in Adams County Colorado. <br />• Water attributable to Aggregate's ownership of Fulton Ditch shares. <br />• A lease with Silver Heights Water and Sanitation Distract for fully <br />consumable wastewater delivered at' the Plum Creek Wastewater <br />Treatment Plant. <br />• Fully consumable water from the Certenniai Water and Sanitation <br />District delivered at Little D_ry Creek or Plum Creek, from McLellan <br />Reservoir, or from Centermial's Ylarcy Gulch Wastewater Treatment <br />Plant. <br />3 <br />
