EXHIBIT F - Reclamation Plan Map (Rule 6.4.6): <br /> Please include the previously mentioned flood control structures on the reclamation <br /> map as appropriate. <br /> Exhibit F Reclamation Plan Map (s) had been updated to include the grading <br /> and revetment areas of the flood control structures. Additionally, and as <br /> described above, plan and profile drawing have been added as Exhibits F <br /> Sheets 4-11. <br /> The permittee will need to acknowledge the following: <br /> DRMS will require a minimum of 5 quarters of groundwater level monitoring data <br /> (preferably collected monthly from wells identified as OW-1 through OW-9 and EW- <br /> 1, 2 and 3 on the reclamation map) to establish " background" water levels in the <br /> vicinity prior to the commencement of dewatering at the site. DRMS will also require <br /> well construction information for all monitoring wells. The permittee will also need to <br /> commit to monthly monitoring of these locations during mining operations, not just <br /> prior to mining and following reclamation as specified in the application. <br /> Pre-mining water levels (minimum of 5 quarters) should be evaluated to determine <br /> the most appropriate well specific "trigger levels" for any proposed mitigation activity <br /> (increased monitoring, modification to pumping, French drains, etc.). When <br /> sufficient data has been collected to establish defensible well specific "trigger <br /> levels", the trigger level data and possible mitigation options for exceedances shall <br /> be submitted by the permittee to DRMS in the form of a Technical Revision for <br /> approval. <br /> The permittee hereby acknowledges that DRMS will require 5 quarters of <br /> groundwater monitoring data collected monthly from Wells OW-1 through OW- <br /> 9 and EW wells 1-3 establish "background"water levels in the vicinity prior to <br /> the commencement of dewatering at the site. In addition, the permittee shall <br /> submit submittal of well construction information and will commit to monthly <br /> monitoring of water levels during mining as well as prior to and following <br /> mining. The permittee requests the DRMS allow the commencement of <br /> dewatering in Cell 1 without 5 prior quarters of water level monitoring. As an <br /> assurance that groundwater mounding will be mitigated, an underdrain <br /> upstream of the proposed clay liner has been specified for Cell 1. The design <br /> and engineering of the underdrain is given in the revised 6.4.7 Exhibit G- <br /> Water Information and includes plan and profile drawing in Exhibit G-Sheets <br /> 1-3 Underdrain. <br /> For the remaining Cells, the permittee agrees to performing monthly water <br /> level monitoring in the proposed wells OW 1- OW-7 and existing Wells EW 1 - <br /> EW-3. The 2 wells for Cell 1 have been removed and the proposed wells have <br /> been renumbered beginning with OW-1 south of Cell 2. <br /> J . <br /> W �l Weiland Inc -_-____ _ - ----------------- <br /> Environmenral Engineering <br />
