• Green/Croissant Sand and Gravel M~esponse to Adequacy Review May 30, 2001 Page 8 6.4.7 EXHIBIT F -Reclamation Plan Mao 13. As noted in Item 1, the Applicant has committed to avoiding operations within 200' of structures until it has obtained either a Structure Agreement or engineering analysis, per DMG Rules (see also item 21, below). The Reclamation Plan Map shows the maximum extent of permitting, which Exhibit S will temporarily modify. 6.4.7 EXHIBIT G -Water Information 14. On March 26, 2001, a Temporary Substitute Supply Plan was submitted to the Office of the State Engineer on behalf of Loveland Ready Mix. This permit for the Green/Croissant Sand and Gravel Mine initiates the permitting process with the State Engineer. Well owners to 600' beyond the permit boundary were researched prior to submittal of permit applications to both the State Engineer and Division of Minerals and Geology. All related groundwater permits will be forwarded to the DMG. 15. As stated in the 112 application report, recovery of the sand and gravel deposit at the Green/Croissant property will require mining through an alluvial aquifer. Well records for this area indicate that the normal groundwater levels are between 4 and 6 feet below ground surface in the vicinity of the site. Boring logs indicate a uniform water surface, with any variation in neighboring well records accounted for by climatic variations in reporting years. 16. Exhibit G acknowledges that the proposed operation will directly affect surface and groundwater systems. Pursuant to Rule 6.4.7, Exhibit G commits to permitting surface water discharge through the Colorado Department of Public Health and Environment, and permitting of groundwater impacts through the Office of the State Engineer (Division of Water Resources). The 112 application also describes the general method for water quality control, to involve the use of an on-site pond system for settling, clarification, and recharge. 17. The Applicant/Operator will commit to implementation of a monitoring program for static water levels in at least three points in the immediate vicinity of the proposed mine. This monitoring program will be initiated prior to commencement of mining activities, allowing for a reasonable amount of time to collect baseline data. We suggest that the DMG condition the 112 permit in this case on its review and approval of monitoring well locations and a plan describing the sampling methods and objectives for the monitoring program.
