M. <br />Water Division 2, Water District 11 <br />Dear Mr. Maly: <br />~wo6•co~ <br />FQ~ <br />N <br />k 1876 ~ <br />Bill Owens <br />Governor <br />Russell George <br />Bcecutlve Director <br />Hal D. Simpson, P.E. <br />State Engineer <br />We have reviewed your July 28, 2004 letter on behalf of Colorado Lime Company, Inc. <br />(d/b/a Calco) requesting renewal of the substitute water supply plan for the Monarch quarry <br />pursuant to C.R.S. 37-92-308(5}. The previous substitute water supply plan was approved by <br />this office on October 14, 2003, The quarry site was previously owned by C.F. & I. Corporation, <br />which mined limestone until the 1960's. Information submitted to DMG {file no. M-2000-98) <br />indicates that quarrying could last for a period of 20 years, however, you state that the plan <br />should not last more than 5 years. Notice has been provided to those on the notification list and <br />no comments have been received from those individuals within the 30-day comment period. <br />Water needs for dust suppression and equipment washing have been and will be <br />supplied from a surface diversion on an unnamed tributary of the South Arkansas River. <br />Diversions are estimated to be 1,000 gallons per day from June through September, totaling <br />0.374 acre-foot annually, all of which is considered to be consumed. The diversions are broken <br />down as follows: <br />Month Estimated Diversions al Estimated Diversions a <br />June 30000 0.092 <br />Jul 31000 0.095 <br />Au ust 31000 0.095 <br />Se tember ~ 30000 0.092 <br />Total 122000 f 0.374 <br />The proposed source of replacement water would be 0.5 acre-feet annually of Twin <br />Lakes Water leased from the Upper Arkansas Water Conservancy District ("District") through <br />August 1, 2006, which the District has stared in North Fork Reservoir, While Twin Lakes water <br />is not 100% consumptive, 0.5 acre-foot is expected to yield 0.374 acre-feet of consumptive <br />credits. <br />
