Applegate Group, Inc. 1499 West 120 Avenue, Suite 200 Denver, Colorado 80234 -2759 Re: 2010 Substitute Water Supply Plan (WDID 0302524) Loloff Pit, Division of Reclamation Mining and Safety No. M -85 -112 SE' /4 NW' /4, Section 4, T5N, R65W, 6" PM Water Division 1, Water District 3 Period of Approval: January 1, 2010 to December 31, 2010 Contact phone number for Mr. Jared Dains: 303 - 452 -6611 Dear Mr. Dains: DEC -. n C 6 We have reviewed your letter of November 17, 2009 requesting renewal of the above referenced substitute water supply plan ( "SWSP ") to replace depletions that result from mining activities. This site was previously covered under the combined SWSP for Aggregate Industries ("Al" or "Applicant ") however in 2007 the site went back to the landowner, Loloff Construction, Inc. The required fee of $257 has been received (receipt no. 3643495). SWSP Operations The Loloff Pit (WDID 0303012) is located in the SE1 /4 of the NW1 /4 of Section 4, Township 5 North, Range 65 West in Weld County. This SWSP will make replacements to the Poudre River for 2010 and accounts for lagged depletions from past and proposed mining operations at the Loloff Pit. As identified in the previous plan, the site was supposed to be dewatered from March through October period and the dewatering pumps will be turned off during the winter. months (November through February) at which time the mined area will fill with water. Due to poor economic conditions and the additional net depletions at this site as the result of the filling the pit, the pit operator did not dewater or mine as planned. Instead the ponds remain full during the entire year and no mining occurred. The operator does not anticipate that the site will be dewatered or mined below the water table in 2010, so the depletions at the site during the period of this SWSP will result only from evaporation and dust control. The replacement sources proposed for this operation include water leased from the Platte River Power Authority and Graham Drainage Ditch Company. Depletions The current exposed ground water at the Loloff Pit site is 7.2 acres, which is estimated to remain the same during the period of this SWSP. The estimated consumptive uses at the site during this plan period are: 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
