Hickenlooper Governor Mike King Executive Director Dick Wolfe, P.E. Director /State Engineer Division of Reclamation, This letter is in response to your application of May 9, 2011 requestie water supply plan ( "SWSP ") for a sand and gravel pit, known as the Eagle Pit (also referred to as the Chambers Pit), to be operated by Lafarge West, Inc. ( "Lafarge" or "Applicant ") in accordance with § 37 -90- 137(11), C.R.S. The Applicant shall be responsible for compliance with this SWSP, but the State Engineer's Office may also pursue the landowner, for eventual compliance. The mine is permitted with the Division of Reclamation, Mining, and Safety under File No. M -80 -136. The $257 fee has been accepted with receipt no. 3650239. The Eagle Pit is located in the NE 1/4 of Section 6, Township 5 South, Range 84 West of the 6 P.M. and it currently operates pursuant to a change of water right and underground water right that were decreed on June 12, 1990 in consolidated Case Nos. 81CW94 and 81CW291. Lafarge proposes to expand mining and water uses beyond the decreed amounts outlined in consolidated Case Nos. 81 CW94 and 81 CW291 and will also expose groundwater as a result of the mining operation. This SWSP will replace depletions incurred by the expansion only. This SWSP will work in conjunction with the above referenced change of water right and underground water right to replace depletions from exposed groundwater, dewatering, and operational uses. Groundwater was not previously exposed at this site. Lafarge anticipates exposing groundwater in the form of a dewatering trench. The projected length of time to expose groundwater is approximately 10 years. In accordance with the letter dated April 30, 2010 (copy attached) from the Colorado Division of Reclamation, Mining, and Safety ( "DRMS "), all sand and gravel mining operators must comply with the requirements of the Colorado Reclamation Act and the Mineral Rules Office of the State Engineer 1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303 - 866 -3581 • Fax: 303 - 866 -3589 www.water.state.co.us
