monitoring, or if the miner receives a complaint from any well owner within 600 feet of the site boundary, <br /> then the miner will evaluate the cause and take action within 7 days and notify the DRMS. <br /> After the DRMS has been notified, the miner will review the data and available information and submit a <br /> report to the DRMS within 30 days. The evaluation will include discussions with the well owner who has <br /> contacted the miner regarding a concern and review of baseline data from the well and vicinity to evaluate <br /> whether changes may be due to seasonal variations, climate, mining, slurry wall lining or other factors. The <br /> report will identify the extent of potential or actual impacts associated with the changes. If the extent of <br /> groundwater changes due to mining or reclamation activities is determined to be a significant contributing <br /> factor that has or may create adverse impacts, the mining associated impacts will be addressed to the <br /> satisfaction of the DRMS. <br /> Miner will begin implementing one or more mitigation measures if mining and reclamation activity is <br /> determined to be a significant factor to groundwater changes requiring mitigation. <br /> Mitigation measures may include, but are not limited to: <br /> ➢ Placing water in a recharge pond to raise groundwater levels around the well. <br /> ➢ Constructing a local clay liner at the edge of the mine Cell (i.e. between the dewatering point and <br /> the well)in order to raise water levels on the well side of the liner and mitigate dewatering effects. <br /> ➢ Cleaning the well to improve efficiency. <br /> ➢ Providing an alternative source of water or purchasing additional water to support historic well use <br /> in terms of water quantity and quality. If needed, water quality parameters will be checked in <br /> affected wells to ensure alternative sources support historic use. <br /> ➢ Modifying a well to operate under lower groundwater conditions. This could include deepening the <br /> well or lowering pumps. All work would be done at the miner's expense with the exception of <br /> replacing equipment that was non-functional prior to mining. <br /> Groundwater Quality Monitoring Plan <br /> Since mining operations at the site will take place inside of slurry wall lined cells, except for establishing the <br /> Freshwater Pond and Siltation Pond, it is unlikely that these operations will have a negative effect on <br /> groundwater quality.To establish pre-mining groundwater quality for the site the permittee will sample MW-2 <br /> on the downgradient side of the site prior to mining. <br /> To establish that mining has had no negative affect on water quality in the area, The Operator will sample <br /> the well listed above annually during the month of January. The water quality samples will be tested for the <br /> analytes listed in Tables 1 through 4 of"The Basic Standards for Ground Water," excluding the radiological <br /> section of Table 1. RMCC will notify DRMS within 7 days of receiving a lab report that indicates any of the <br /> standards set forth in Tables 1 through 4 have been exceeded. If a lab report indicates an exceedance, a <br /> new sample will be taken to verify the exceedance and discount lab contamination. Any water quality lab <br /> results will be included in the DRMS annual report for the site. <br /> Annual groundwater testing will be conducted for the life of the mine unless the requirement has been <br /> reduced or eliminated through the Technical Revision process with the DRMS. <br /> Red Tierra Equities, LLC—Section 20 Mine—MLRB 112 Permit Application <br /> Exhibit G-5 <br />
