The required fee of $217 for the renewal of this substitute <br />supply plan has been submitted. The original supply plan was approved on January 27, 1998. <br />The original supply plan accounted for 6.93 acre-feet per year to be used for dust <br />suppression and anywhere from 27.82 to 33.88 acre-feet per year of water lost in mining <br />product. The proposed supply plan is to continue to replace depletions to the pit caused by the <br />removal of wafer in the mining product and water used for dust suppression. The plan <br />estimates that 27.2 acre-feet per year will be lost in mining product and 4.0 acre-feet per year <br />will be lost in dust suppression. The plan also replaces depletions caused by the pumping of <br />well permit no. 19808-R. The water from this well is used for concrete production at the site <br />and the total use will be 12.8 acre-feet per year. Well permit no. 19808-R is permitted and <br />decreed for irrigation. <br />The exposed surface area at the site is 18.3 acres. The Howe Pit had 26.6 acres that <br />were exposed prior to 1981. Since the pre-1981 acreage at the site exceeds the current <br />exposed acreage, no evaporative losses require augmentation. <br />The source of replacement water is 25 Fulton Ditch shares, which were historically used <br />on the site, during the summer. Winter replacements will be supplied from a lease of reusable <br />effluent from the City of Greeley in the amount of 19.7 acre-feet. The 25 shares of Fulton Ditch <br />water represent 97.5 acre-feet of water available at the headgate. Conveyance losses and <br />consumptive use of ten percent and 50 percent respectively are determined in Water Court <br />Case No. 82CW393. <br />A monthly breakdown of depletions and replacements is shown in the attached Table <br />No. 4 that was submitted with your report. <br />I hereby approve this substitute water supply plan, in accordance with Section 37-80- <br />120, C.R.S., (1991), subject to the following conditions' <br />' <br />;fi <br />,~ <br />:a. <br />i~ ~, <br />~' Y:' Y <br />~ .. <br />:;::z a <br />1K• <br />~;( <br />~: <br />~~ <br />."y <br />:;,. <br />$~ . <br />.a <br />H~ <br />,u~ <br />
