Hickenlooper Governor Mike King Executive Director Dick Wolfe, P.E. Director /State Engineer This letter is in response to your application of June 20, 2011 on behalf of Broken Arrow Investments, LLC ( "Broken Arrow" or "Applicant ") requesting to amend the substitute water supply plan ( "SWSP ") for a sand and gravel pit operated by Applicant in accordance with § 37 -90- 137(11), C.R.S. The request also sought to extend the expiration date through December 31, 2012 to be consistent with lease period for the City of Greeley effluent. The Applicant shall be responsible for compliance with this SWSP. The required fee of $257 for the SWSP has been paid (receipt no. 3650869). The previous SWSP approval for the Derr Pit was approved for the period of October 1, 2010 through December 31, 2011 (or September 30, 2012 if extended pursuant to condition no. 1 of the SWSP). This SWSP amends and supersedes the prior approval for the period beginning June 20, 2011. SWSP Operations This SWSP seeks to replace depletions resulting from mining at the Derr Pit. The Derr Pit is located in the SW1 /4 of the NE1 /4 and the SE1 /4 of the NE1 /4 of Section 4, Township 5 North, Range 65 West of the 6 P. M. in Weld County. Broken Arrow plans to mine the Derr Pit for the next 15 to 18 years in phases. The dry mining of Phase 1 began in early 2010. During Phase 1 no dewatering occurred since all mining occurred above the groundwater table. As part of Phase 2 the operator plans to begin dewatering of the site. In order to facility dewatering a 2,007 foot long and 5 feet wide dewatering trench will be constructed along with a 0.52 acre dewatering pond. Depletions that result from the proposed dry- mining operation during Phase 2 include evaporation, dust control, and water lost in the mined product. The source of replacement water is fully consumable effluent leased from the City of Greeley.
