Hickenlooper Governor Mike King December 5, 2011 Executive Director Dick Wolfe, P.E. Director /State Engineer RE: Substitute Water Supply Plan for DeBeque Pit DRMS #M -81 -058 ✓ Sections 8 & 9, T9S, R97W, 6th P.M. Water Division 5, Water District 72, Mesa County Approval Period: May 17, 2010 through April 30, 2012 Contact Phone Number for Mr. McLean: 303 - 651 -1468 Dear Mr. McLean: We have reviewed your March 30, 2010 and March 1, 2011 letters . requesting renewal of the substitute water supply plan ( "SWSP ") for the DeBeque Pit on behalf of Kirkland Construction, RLLP ( "Kirkland" or "Applicant "), in accordance with § 37 -90- 137(11), C.R.S. The required fee of $257 for the renewal request has been submitted (receipt nos. 3645225 and 3649317). The original plan was approved on June 3, 2003 and it was most recently renewed on April 28, 2008. SWSP Operations This SWSP seeks to replace depletions resulting from mining operations at the DeBeque Pit. The depletions that result from the mining operations are evaporation from exposed ground water, water lost in the mined product, and water used for dust suppression. The mine is located in. Mesa County in the SE1 /4 of Section 8, and the SW1 /4 of Section 9, Township 9 South, Range 97 West of the 6 P.M. After mining operations are completed, the site will be reclaimed as an unlined ground water pond with a surface area not to exceed 11.6 acres and with a net depletion of 27.62 acre -feet during the April through October call period. Currently there are 3.6 acres of ground water exposed at the site. Evaporation losses from the 3.6 acres of exposed ground .water are replaced by a plan for augmentation that was decreed in case no. 2005CW076. This SWSP will replace depletions that result from the on- going mining operation and the exposure of additional ground water (in addition to the 3.6 acres previously exposed). The existing 3.6 acre pond will be contiguous with the added pond area. The proposed sources of replacement water for this pit are 38.7 acre -feet of historical net stream depletions during April through October from the dry-up of 19.1 acres of land historically irrigated with 6.1 shares of the Larkin Irrigation Company ( "Larkin Ditch "). The post mining depletions will also be covered by the dedication of the 6.1 shares in the Larkin Ditch. 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. The DRMS letter identifies four approaches to satisfy this requirement. The 4 approach requires Office of the State Engineer 1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303 - 866 -3581 • Fax: 303- 866 -3589 www.Water.stale.co.us RECEIVED DEC 07 2011 Division of Reclamation, Mining & Safety
