Simpson, P.E. <br />State Engineer <br />This letter is in response to the application submitted in August of 2003 requesting a <br />substitute water supply plan (SWSP) for a sand and gravel pit to be operated by S.W. Meadows; <br />LLC ("Applicant") in accordance with Section §37-90-137(11), C.R.S. Additional information for <br />the plan was submitted November 24, 2004, The Applicant shall be responsible for compliance <br />with this plan, but the State Engineer's Office may also pursue the landowner for eventual <br />compliance. The required fee of $1,343 for the substitute water supply plan has been paid. <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 />You have provided a monthly breakdown of the annual depletions at this site. Annually, <br />these are made up of 14.2 acre-feet of evaporative loss from 4.8 acres of water surface exposed <br />after December 31,1980, 14.7 acre-feet of water lost with 500,000 tons mined product, 15.5 <br />acre-feet consumed by hatching 150,000 cubic-yards of concrete and 1.9 acre-feet used for dust <br />suppression. <br />According to the plan, a slurry wall wil! be constructed around the perimeter of the site to <br />hydraulically disconnect the mine from the surrounding groundwater 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 />According to the plan, an existing well, permit no. 20136-R, will occasionally be used for <br />dust suppression and concrete hatching. The maximum monthly amount that will be pumped <br />from the well will not exceed the values specified in attached Table 2. <br />
