estimated at 0.38 acres. Journey Ventures, LLC plans to keep the site dewatered throughout <br />the life of the mine. <br />Evaporation data was taken from NOAA Technical Report NWS 33, Evaporation Atlas for the 48 <br />Contiguous United States. The annual gross evaporation was determined to be 45 inches for <br />this location. Monthly evaporation percentages are established by guidelines set by the State <br />Engineer's Office. To determine precipitation, data from the National Weather Service for <br />Greeley, CO (053553) (1967-2007) was used. The long-term average precipitation at the <br />Journey Ventures Pit is estimated at 14.04 inches. Effective precipitation is calculated as 70% of <br />the total precipitation. The net evaporation is the difference between gross annual evaporation <br />and effective precipitation. The resulting net evaporation is 2.93 feet. <br />The maximum evaporative loss from the 0.38 acres is 1.11 ac-ft. <br />Operational Loss <br />The average annual production from the Journey Ventures Pit site is estimated at 250,000 tons. <br />Using 4% moisture content, the total associated consumptive use for water retained in the <br />material mined is 7.4 ac-ft. <br />Dust control use is 10,000 gal/day, 6 days/week, 4 weeks/month for 10 months of the year. This <br />equates to 7.4 ac-ft. <br />Maximum annual operational loss is estimated to be 14.8 ac-ft for Phases 3-11. <br />Consumptive Use <br />The maximum annual consumptive use at this site during the mining operation is estimated to <br />be 15.91 ac-ft for Phases 3-11. <br />Replacement Water <br />The replacement of consumptive uses at the site is will be accounted for in a substitute water <br />supply plan (SWSP) approved by the State Engineer. The SWSP will be obtained prior to any <br />mining activities occurring that expose groundwater. <br />Surroundinq Water Rights <br />Figure Exhibit G-1 shows the permitted wells within 600 feet of the mining limits. The well <br />information and locations were obtained from the Division of Water Resources online mapping <br />well permit locator. This well and water rights information was cross checked with the State's <br />CDSS. Between the sources, all permitted and decreed wells are included. Table Exhibit G-1 <br />below is a corresponding list of wells as numbered in Figure Exhibit G-1. <br />Journey Ventures, LLC <br />J&T Consulting, Inc.
