ditches/ponds in the locations where direct discharge to an existing adjacent irrigation lateral is <br /> not available to ensure that stabilized groundwater levels are maintained. They will discharge <br /> dewatering flows into existing adjacent irrigation laterals where possible to limit the disturbance <br /> to the surrounding land. A slurry wall liner is proposed around the individual phase and will likely <br /> be installed prior to mining starting. <br /> To summarize the mitigation process, as each phase of mining/dewatering occurs, IHC Scott, Inc. <br /> will monitor the groundwater levels adjacent to mine as each phase progresses. If groundwater <br /> levels drop to a level that prevents an adjacent well from performing acceptably, according to that <br /> well's owner, IHC Scott, Inc. will either implement a groundwater recharge ditch/pond near the <br /> well in order to raise the groundwater level in the vicinity of the well and hence return it's operation <br /> to acceptable standards, or will negotiate an agreement with that well owner to replace the well <br /> or provide replacement water via other means until the mining and reclamation activities are <br /> concluded but it is not anticipated that any groundwater levels will drop since the slurry wall will <br /> be installed prior to exposing groundwater. <br /> Groundwater wells that are not owned by IHC Scott, Inc. (Table G-1)are potentially located within <br /> 600 feet of the mining limits. The exact physical location of these wells will be determined during <br /> the SWSP and well permit application processes. If wells are found to be within 600 feet of the <br /> mining limits, IHC Scott, Inc. will either obtain a well waiver from the owner of the well, or provide <br /> an agreement with the well owner that IHC Scott, Inc. will mitigate any material damage to the <br /> well that is directly attributable to the mining and reclamation of the site. <br /> All other wells within 600 feet of the mining limits are either owned by IHC Scott, Inc., or are <br /> monitoring wells therefore groundwater impacts to these wells do not need to be addressed. <br /> See the attached Piezometer Location Map, and Piezometer Data Summary, which show the <br /> locations of monitoring wells around the perimeter of the site that IHC Scott, Inc. has either <br /> installed or has access to, and the groundwater level data that has been collected for each well. <br /> ' IHC Scott,Inc. <br /> UT Consulting,Inc.
