In order to make replacements for the <br />additional uses at the site, United has amended one of the original leases with the CRWCD. <br />Depletions <br />The water uses at the Gypsum Ranch Pit as described in Case No. 2002CW211 include <br />industrial uses for sand and gravel washing, dust control, concrete production, pond <br />evaporation, truck and equipment washing, and domestic uses. During the requested plan <br />period, the depletions that will be replaced by this SWSP are limited to additional water use for <br />aggregate production and dust control at the site. You have estimated the additional water use <br />for aggregate production and dust control to be approximately 10.0 acre-feet above the decreed <br />volumes identified in the augmentation plan in Case No. 2002CW211. The volume of depletions <br />specified in Case No. 2002CW211 and the estimated volume of depletions for the additional <br />water uses are summarized in the table below: <br />Uses <br />Decreed Amount <br />(acre-feet) <br />Additional Water in the <br />SWSP acre-feet <br />Total <br />(acre-feet) <br />Aggregate Production <br />5.8 associated with <br />200,000 tons <br />1.5 associated with <br />100,000 tons <br />7.4 associated with <br />300,000 tons <br />Dust Control <br />6.5 <br />8.5 <br />15.0 <br />Concrete Production <br />11 <br />0 <br />11 <br />Truck Washing <br />0.70 <br />0.7 <br />Pond Evaporation <br />13.4 <br />0 <br />13.4 <br />Domestic <br />0.05 <br />0 <br />0.05 <br />Total <br />37.55 <br />10.0 <br />47.6 <br />The attached Table 1 provides a monthly breakdown of the depletions. The depletions <br />described in Case No. 2002CW211 total 37.5 acre-feet per year; the additional depletions for <br />aggregate production and dust control are estimated to be 1.5 acre-feet per year and 8.5 acre- <br />feet per year, respectively. The total additional water use to be replaced under this SWSP is <br />10.0 acre-feet/year. <br />Replacements <br />The Gypsum Ranch Pit will continue to use the historical consumptive use credits from <br />the dry -up of historically irrigated lands under the C M Stremme and Gates Ditch during the <br />irrigation season, as decreed in Case No. 2002CW211. The amounts of the C M Stremme and <br />Gates Ditch priorities that have been dedicated to the existing augmentation plan in Case No. <br />2002CW211 are listed in the table below: <br />Case <br />Priority <br />Appropriation <br />Adjudication <br />in Case No. <br />2002CW211 <br />Number <br />Number <br />Date <br />Date(cfs) <br />=DecreedAmount <br />CA 385 <br />142 <br />06/05/1886 <br />_05/31/1891 <br />03/05/1901 <br />..436 <br />0.436 <br />CA 385 <br />160 <br />03/05/1901 <br />0.17 <br />0.093 <br />0.093 <br />
