This plan was <br />submitted pursuant to C.R.S. 37 -90- 137(11). The fee of $1,593 for the substitute water <br />supply plan has been received (receipt no. 3666998). <br />Plan Operation <br />The Sandy Acres Pit is located on E -470's property in the SE1 /4 of Section 26, Township <br />1 South, Range 67 West of the 6th P.M. The mining operations at the Sandy Acres Pit resulted in <br />the creation of an unlined pond, as shown on the attached Figure 1. The Sandy Acres Pit is no <br />longer an active mining site and there are no plans for future mining. E -470 purchased the <br />property containing the Sandy Acres Pit in 2000 in conjunction with the construction of the E- <br />470 highway. This SWSP seeks to replace the evaporation depletions from the Sandy Acres Pit <br />using water leased from the Central Colorado Water Conservancy District ( "Central "). <br />Note, that the approval of this substitute water supply plan does not relieve the <br />Applicant and /or landowner of the requirement to obtain a Water Court decree <br />approving a permanent plan for augmentation or mitigation to ensure the permanent <br />replacement of all depletions, including long -term evaporation losses and lagged <br />depletions after gravel mining operations have ceased. The Applicant indicated that the <br />Sandy Acres Pit reclamation plan was amended on September 3, 2014 from unlined <br />ground water pond to backfilling the site. Therefore in order to eliminate the <br />evaporation depletions associated with the pit, E -470 will backfill the pit with inert <br />material from the Brannan Sand and Gravel Company ( "Brannan ") Pit 29 (DRMS M1980- <br />183). By the next renewal request of this SWSP the Applicant or its successor in <br />Office of the State Engineer <br />1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303 - 866 -3581 • Fax: 303 - 866 -3589 <br />www.water.state.co.us <br />
