Water Division 1, Water District 3, Weld County Approval Period: April 1, 2011 through March 31, 2012 Contact Phone Number for Ms. Hatcher.• 970-223-3706 Dear Ms. Hatcher: We have reviewed your letter dated February 11, 2011, requesting renewal of the above referenced substitute water supply plan to cover depletions caused by an existing mining operation. The required fee of $257.00 for the renewal of this substitute supply plan has been submitted (receipt no. 3649126). The original supply plan was approved on March 25, 1994 and it was most recently renewed on August 24, 2010 for operations through March 31, 2011. Plan Operation This plan seeks to replace depletions resulting from the mining operation at the Geisert gravel pit (permit no. 50425-F, WDID 0303030), operated by Weld County ("County"). The County operates this site to produce aggregate for road base and public works construction projects. Depletions from the mining operation during this SWSP period will result from evaporation from the exposed ground water, water lost with the mined product, and water removed by the "first fill". No dewatering is provided or sought under this plan. The proposed replacement source is fully consumable water leased from the City of Greeley ("Greeley"). 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. If the information you are providing to DRMS is included under the approaches numbered 1 - 3, a copy of that information needs to also be provided to this office (the Division of Water Resources). If the information you are providing to DRMS is pursuant to approach no. 4, you REGEMD Office of fette Engineer 1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303-866-3581 • Fax: 303-866-3589 AR 0 7 2 011 http://water.state.co.us Division of i-eGkanation, Mining and 34etY
