Groundwater Monitoring & Response Plan <br />well(s) during Step 3. Each step of the response and mitigation process is discussed in further <br />detail below. <br />Elam will initiate Step 1 of the response and mitigation process by contacting the affected well <br />owner(s) to request authorization to access the well(s) to obtain a water level measurement. The <br />measured water level will be used to refine the impact assessment. If the projected impact is not <br />confirmed by the refined assessment, no further actions will be taken under the response and <br />mitigation process. If the refined assessment confirms the projected impact, Elam will initiate <br />Step 2 of the response and mitigation process. <br />Operational changes will be investigated during Step 2 to mitigate the threat of impact to the <br />suspect well(s). Such changes will be evaluated with respect to long -term and short-term <br />effectiveness and may include, but are not necessarily limited to, reduction of the dewatering rate <br />or use of an infiltration trench/gallery. If the changes can be effectively implemented as a short- <br />term mitigative measure, then the changes will be implemented and maintained through the <br />remainder of the dewatering period that year. If the changes can be effectively implemented as a <br />long -term mitigative measure, the changes will become part of the long -term mine plan for the <br />pit. If the operational changes cannot be effectively implemented as an effective long -term <br />solution for mitigation of the impact, Elam will initiate Step 3 of the response and mitigation <br />process. <br />Step 3 of the response and mitigation process will be initiated by contacting the affected well <br />owner(s) to discuss the potential impact and the options for mitigation of the threat. Potential <br />options for mitigation of the threat would be developed based on model predictions, groundwater <br />monitoring observations, and well information. <br />Mitigative measure options at the affected well(s) may include 1) lowering the existing well <br />pump, 2) deepening the well and subsequently lowering the pump, or 3) drilling a new deeper <br />well to replace the existing impacted well. If implementation of the selected measure requires the <br />existing well be taken offline, Elam will supply the residence with a temporary mobile potable <br />water supply until the existing or new well is returned to normal operation. To ensure immediate <br />delivery of a temporary water supply, Elam will establish a relationship with a local water <br />supplier prior to the start of mining operations at the Pit.
