Director /State Engineer Re: Heit Substitute Water Supply Plan (WDID 0202598) Heit Sand and Gravel Mine, DRMS Permit No. M- 2003-016 (WDID 0203038) r, Section 13, T2N, R67W, GtP.M. Water Division 1, Water District 2, Weld County RECEIVED Approval Period: September 1, 2013 through August 31, 2014 Contact phone number for Mr. Joe Kraig: (719) 599 -8100 I/AUG 21 2013 Dear Mr. Kraig: DIVISION OF RECLAMATION MININGAND SAFETY We have received your letter dated June 28, 2013 requesting the renewal of the above referenced substitute water supply plan ( "SWSP ") to cover depletions caused by an existing gravel mining operation at the Heit Sand and Gravel Mine in accordance with § 37 -90- 137(11), C.R.S. The required fee of $257 for this SWSP renewal has been received (receipt no. 3660724). Plan Operation The Heit Sand and Gravel Mine perimeter was lined with a slurry wall in accordance with the State Engineer's Lining Criteria, and was approved by the Division Office on June 24, 2009. In accordance with paragraph 21 of the General Guidelines for Substitute Water Supply Plans for Sand and Gravel Pits, the applicant is required to provide replacement for all native ground water remaining within the lined area that is put to beneficial use except for the water removed with the mined product. The water may be removed from within the lined area and returned to the stream system through surface flow or ground water recharge without need for replacement, so long as the operator does not put the water to beneficial use. Replacement shall be made for native ground water that is lost to evaporation. For purposes of this SWSP, it is assumed that all water within the lined area is trapped native ground water. Therefore, this plan will account for depletions resulting from evaporation of exposed water within the lined area. Operational depletions at the site will consist of water used for dust control and for washing of the mined aggregate using an onsite production well. All water used from the production well must be replaced in time, place and amount including water used for washing of mined product. Total depletions for the Heit Sand and Gravel Mine during the period of this SWSP will be replaced by fully consumable water leased from the City and County of Broomfield. In accordance with the letter dated April 30, 2010 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 required 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 identified four approaches to satisfy this requirement. A surety reduction was approved on March 23, 2010 by DRMS reducing the bond by $110,614 — representing the remaining 20% of the construction bond that was posted for the slurry wall. The remaining bond of $197,280 remains in place to cover the remainder of the Mice 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
