( "Coulson" or "Applicant') in accordance with Section §37- 90- 137(11), C.R.S. The Applicant shall be responsible for compliance with this plan. The required fee of $257 for the substitute water supply plan has been submitted (receipt no. 3653131A). Plant Operation This plan seeks to replace depletions resulting from mining at the Gardels Gravel Pit ( "Gardels Pit "�. Gardels Pit is located in the N1J2 of Section 19, Township 5 North, Range 68 West of the 6 P.M. Mining at this site began in 2004 and by 2006 was completed, The site is currently undergoing final reclamation. The west cell has been lined and was approved as a lined reservoir (WDID 0403396) by the State Engineers Office through a letter dated October 4, 2012. Approximately 9.39 acres of exposed ground water remain within the DRMS permit boundary. There are no ground water areas within the DRMS permit boundary that were exposed prior to January 1, 1981, This SWSP only covers the evaporative losses from the exposed ground water associated with the Gardels Pit. 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 and Regulations for the protection of water resources. The April 30, 2010 letter from DRMS requires that you provide information to DRMS to demonstrate you can replace long term injurious stream depletions that result from mining related exposure of ground water, In accordance with approach nos, 1 and 3, you have indicated that a bond has been obtained for $291,800 through the Division of Reclamation, Mining, and Safety ("DRMS ") for lining of the pit thus ensuring that depletions from groundwater evaporation do not occur in the unforeseen event, or events, that would lead to the abandonment of the Pit. Information has not been submitted to our office to verify that this bond is sufficient to cover the cost of lining or Office of the State Engineer 1313 Sherman Street, Suite 818 • Denver, 0080203 • Phone: 303 -866 -3581 • Fax: 303 - 866 -3589 www.watenstate,co.us
