[NVIRONMENT, INC. ~ PAGE 3 <br />JULY 22, $Q01 ~ ~ - <br />source. The monthly recap sheet and Table D2 -column 5 will be {teed to calculate the <br />amount of water needed based on the amount of lake sued aeet< that exists in any given <br />month. <br />Tables A2 thnt C2 are based on this information, <br />I. Nu more Uri 2a acres of take :uea will exist during dewatering operations. <br />2. Burlington-Wellington Ditch shares will be used as irrigation season makeup water <br />temporazily until Denver Water Department takes over the mine after 2006. <br />3 From the Little Burlington ditch to the river is 2.25 miles: <br />4. FRICO shares from Stanley Lake will be used as make up water during the non- <br />irrigation season temporarily until Denver water takes over the mine after 2006. <br />Water will be delivered via Big Dry Creek that enters the river 5 miles north of this <br />mine. Copies of the FRICO shares are attached for you; file. <br />5. The distance from Stanley Lake to mouth of Big Dry Creek and South Platte River <br />is 22.5 miles. <br />6. Transportation loss factor used is 0.2546 per mile <br />Table A2 is the recap sheet for this mine where the unit numbers are multiplied by 25 <br />acres to get ac-inches. Column 5 then sums columns 2, 3, 8c 4 tq show total evaporation <br />losses. Columns 5 Bc 6 are from Table F2, and column 7 sums 5 8c 6 and converts to acre-ft. <br />It has data from Table B2, from Table C2, from Table D2 and from Exhibit 1. The last <br />column of this tables shows the amount of water delivered each month to the river. <br />Our plan is to operate the mine under Scenario Two, accounting for actual Take area <br />and makeup water supply using the monthly recap sheet. If dewatering stops then your office <br />would be contacted and advised that the source of makeup water has shifted from Suburban's <br />water sources to Denver Water Department water. Thanks for your help and please call me if <br />you have any questions. <br />Sincerely, <br />Environment, Inc <br />~~.~ ~ <br />Stevan L.
