The site contains four slurry walled areas, designated as cells A through D. Together these four cells are planned to eventually be connected via pipelines, by others, and become Shores Lake (WDID 0503900) as adjudicated in case no. 2000CW83. Cells A, B, C, and D were initially dewatered and dry mined. A slurry wall was constructed around cells A and B and lining for these cells was approved on January 11, 2007. A slurry wall was also constructed around cell C and lining was approved on December 7, 2009. A slurry wall was constructed around cell D and was approved on October 8, 2013. The only remaining area to be mined at the site is the area known as the Burch property. A substitute water supply plan ( "SWSP ") for the Shores Pit was submitted to the State Engineer's Office ( "SEO ") on December 17, 2014 and this SWSP is pending evaluation. The SEO has no objection to the request for financial warranty reduction for the Shores Pit, provided the Applicant will continue to operate the remaining area to be mined at the site in accordance to an approved SWSP or approved plan for augmentation. The applicant may contact the State Engineer's Office with any questions. 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 F 303.866.3585 www.water.state.co.us —C 0 * 1876
