Water Division 1, Water District 2, Weld County Approval Period: July 1, 2012 through June 30, 2014 Contact Phone Number for Mr. Rick Parsons: 303 - 667 -5067 Dear Mr. Parsons: DEPARTMENT OF NATURAL RESOURCES DIVISION OF WATER RESOURCES August 17, 2012 John W. Hickenlooper Governor Mike King Executive Director Dick Wolfe, P.E. Director /State Engineer RECEIVED AUG202012 Division of Reclamation, Mining & Safety We have received your letter of July 10, 2012, requesting approval of the above referenced substitute water supply plan ( "SWSP ") to cover depletions caused by an existing gravel mining operation. The required application fee of $1,593 for an expired SWSP has been submitted (receipt no. 3656379). The original supply plan applied for by South Platte Sand and Gravel LLC was approved on April 30, 2001 and expired on December 31, 2011. On May 21, 2012 the Division Office sent a Show Cause Order to Gilcrest Reservoir notifying them that the SWSP had expired. In response to the Show Cause Order, a new SWSP application was submitted to the State Engineer's Office on July 30, 2012. Plan Operation This plan seeks to replace depletions resulting from mining at the S &H Mine Gravel Pit ( "S &H Pit ") operated by Gilcrest Reservoir LLC ( "Applicant "). Gilcrest Reservoir assumed operational and ownership control of the mining site from Platte Sand and Gravel LLC when the Succession of Operators was approved by the Division of Mining Reclamation and Safety ( "DRMS ") on February 2, 2011. There are no current mining activities occurring at this pit and as such the only depletions covered under this SWSP are those caused by evaporation from a ground water pond that resulted from past mining operations. Should mining activities resume an amendment to this SWSP will be required. The S &H mine permit area covers approximately 750 acres and is divided into different cell mines. The two structures included in this SWSP are Sharkey's Reservoir (WDID 0203977) and Sharkey's Pond. The liner of Sharkey's Reservoir has been completed and based on a Division of Water Resources liner approval letter dated May 22, 2009, the pit has been lined to the design standard referenced in the August 1999 State Engineer Guideline for Lining Criteria for Gravel Pits. The proposed replacement source is water stored in priority within Sharkey's Reservoir. Depletions According to the information submitted, no water surface was exposed within the permit boundary prior to January 1, 1981. Sharkey's Pond currently exposes 10.8 acres of ground water. Using an annual gross evaporation of 43 inches per NOAA TR -33, and an effective precipitation of 8.66 inches per year, the Office of the State Engineer -- 'Pr S 1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303 - 866 -3581 • Fax: 303 - 866 -3589 www.water.state.co.us
