RECEIVED <br />Water Division 1, Water District 2, Weld County <br />Approval Period: September 1, 2007 through August 31, 2008 ~EP 14 2001 <br />Contact information for Mr. Andrew Rodriguez: 303-833-1416 ~~~~~~~~~ ~~ ,~~~lamation, <br />Mining and Safety <br />Dear Mr. Rodriquez: <br />This letter is in response to the July 3, 2007 request for a substitute water supply plan <br />("SWSP") for a sand and gravel pit to be operated by S.W. Meadows, LLC ("Applicant") in <br />accordance with Section §37-90-137(11), C.R.S. The Applicant shall be responsible for <br />compliance with this plan, but the State Engineers Office may also pursue the landowner for <br />eventual compliance. The required fee of $257 for the substitute water supply plan renewal has <br />been paid. <br />Plan Operation <br />According to the plan, a slurry wall will be constructed around the perimeter of the site to <br />hydraulically disconnect the mine from the surrounding ground water system. Once the slurry <br />wall is constructed the site will be dewatered and the area will be dry mined. For purposes of this <br />SWSP it is conservatively assumed that the slurry wall will be ineffective. Therefore, depletions <br />accruing to the South Platte River will be replaced as if the slurry wall did not exist. <br />The applicant has posted a bond through the Division of Reclamation Mining and Safety <br />permit for $1,050,152, for reclamation of the site including completion of the slurry wall. <br />Mining at the site will result in depletions from evaporation, water lost in mined product, <br />concrete hatching and dust control. The depletions will be replaced by fully consumable water <br />leased from the City of Broomfield. <br />Depletions <br />The anticipated net annual depletions for this plan is 46.3 acre-feet for operation at a site <br />with up to 4.8 acres of water surface exposed after December 31,1980. <br />
