Water Division 1, Water District 5, Weld County Approval Period: November 1, 2012 through February 28, 2013 2013, see comment #1) Contact phone number for Mr. Andy Rodriguez: 303 - 833 -1416 Dear Mr. Rodriguez: We have reviewed your letter dated August 27, 2012, requesting renewal of the above - referenced substitute water supply plan to cover depletions caused by an existing gravel mining operation, operated by Bestway Concrete & Aggregate ( "Applicant "). The required fee of $257.00 for the renewal of this substitute water supply plan has been submitted (receipt no. 3657244). The original plan was approved on May 21, 2001 and was most recently approved on January 26, 2012 for operations through October 31, 2012. Plan Operation This plan seeks to replace depletions resulting from mining operations at the Shores gravel pit. The site contains four slurry walled areas, designated cells A through D, as shown on the attached Figure 1. Together these four cells are planned to eventually be connected via pipelines, by others, and become Shores Lake (WDID 0503900) as adjudicated in 00CW0083. Cells A, B and C were initially dewatered and dry mined. A slurry wall was constructed around cells A and B and lining for these cells was approved in January 2007. A slurry wall was also constructed around cell C and was approved in December 2009. A slurry wall was constructed around cell D but has not yet been tested or approved. During the period of this plan mining will only occur in cell D. The depletions that result from mining operations at the Shores pit are evaporation, water lost in mined product, concrete batching, dust suppression and dewatering. The proposed replacement sources are 0.5 shares of the Rural Ditch and a lease with the City of Aurora. These accretions are applied to this plan against the evaporation and operational depletions at the site. 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.
