Hickenlooper <br />Governor <br />Mike King <br />Executive Director <br />Dick Wolfe, P.E. <br />Director /State Engineer <br />RECEIVED <br />/MAY U 12015 <br />-TV: DIVISION OF RECLAMATION, <br />MINING AND SAFETY <br />We have reviewed your letter dated February 13, 2015 and updated letter of April 1, 2015 in <br />which you request renewal of the above referenced substitute water supply plan ( "SWSP ") on behalf of <br />Connell Resources, Inc. ( "Applicant ") in accordance with 5 37 -90- 137(11), C.R.S. to cover depletions <br />caused by gravel mining operations at the SerFer Pit (DRMS Permit No. M- 2008 -006). The required <br />renewal fee of $257 has been submitted (receipt no. 3668458). The original SWSP was approved on July <br />2, 2008 for operations beginning August 1, 2008, and was most recently renewed on April 21, 2014 for <br />operations through March 31, 2015. <br />SWSP Operations <br />This SWSP seeks to replace depletions resulting from mining operations at the SerFer Pit. <br />Mining operations at the SerFer Pit began in January 2011 and ended in 2014, with reclamation of the <br />pit beginning in late 2014 and continuing into early 2015. Construction of an impermeable clay liner <br />at the site is complete and a 90 -day leak test of the liner began on February 9, 2015. The Applicant <br />plans to start de- watering inside the lined area as part of the leak test on April 6, 2015 and intends <br />to keep the site in a dewatered state for the duration of the leak test. As part of the lining of the <br />pit, the dewatering sump was filled in and the settling ponds between the sump and the Poudre River <br />will be filled in prior to April 1, 2015. Therefore, it is anticipated that there will be no exposed <br />ground water remaining at the site after April 2015. Depletions wilt consist of evaporative and <br />operational depletions occurring during this plan period, and lagged depletions due to past mining <br />and the cessation of dewatering operations at the site. The proposed replacement source is excess <br />credits resulting from a recharge project at the Timnath- Connell Pit (M- 1999 -050, WDID 0303018). <br />Depletions <br />Depletions at the SerFer Pit will consist of evaporation of exposed ground water, water <br />removed in the mined product, and water used for dust control purposes during this plan period, and <br />lagged depletions due to past mining and dewatering operations at the site. <br />Currently there are approximately 7.0 acres of ground water exposed at the site within the <br />lined area. After dewatering begins on April 6, the amount of exposed ground water will gradually <br />decline to zero. For the purposes of this SWSP, you have assumed that 7.0 acres will be exposed for <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 />
