Rernediation and Monitoring Measures for <br /> NEWMONT <br /> Cyanide Spillsi Releases <br /> Sustainability and External Relations <br /> i) In the event of a release of cyanide solution beyond an engineered containment <br /> structure, the Process Manager or control room will be notified and will take <br /> immediate measures to stop the release. <br /> ii) If necessary, emergency berms or dikes will be constructed to contain the release <br /> until necessary equipment and personnel can be mobilized to clean up. <br /> iii) Personnel and community safety is always the first priority. In case of a leak or <br /> release during off loading, the transfer driver will shut system down and notify <br /> operator of area to call appropriate personnel and equipment. <br /> iv) In case of an uncontained seepage, notification to foreman, general foreman or <br /> manager will be made. Employees using a gas monitor and appropriate PPE will <br /> control seepage. If employees are unable to contain the seepage, rescue <br /> personnel will be brought in for control. <br /> d) Releases during fires and explosions: <br /> (i) Do not use straight streams. <br /> (ii) Use water spray, fog or alcohol resistant foam to extinguish fire and to reduce <br /> vapors. <br /> (iii) Control/contain fire water runoff for later disposal. <br /> f)/g Overtopping of Leaching Impoundment(Process Ponds)/Power Outages: <br /> (i) During a severe emergency (power outages, pump failures, etc.), if the operator <br /> determines there is a possibility that any of the leaching impoundment could <br /> overtop, management personnel will be notified and heavy equipment and <br /> personnel will be mobilized to construct an emergency berm adjacent to the area <br /> to contain the release. <br /> (ii) Process solutions contained in a temporary emergency containment basin will be <br /> pumped back to the process following the emergency. <br /> (iii) Cyanide-contaminated soils will be removed and disposed of on the heap leach <br /> pad or tailings impoundment. If necessary, soils would also be neutralized. <br /> j) Run-off from Heap Leach Pads: <br /> i) In the event that runoff is observed from the leach pads, management personnel will <br /> be notified and heavy equipment and personnel will be mobilized to construct an <br /> emergency berm area adjacent to the area to contain the release. <br /> ii) Process solutions contained in a temporary emergency containment basin will be <br /> pumped back to the process following the emergency. <br /> iii) Cyanide-contaminated soils will be removed and disposed of on the heap leach pad <br /> or tailings impoundment. If necessary, soils would also be neutralized. <br /> ------------------------------------------------------------7----------------------------------------------------------------------------------------------------------------------- -------- -------------------------------------------------- <br /> Department THIS DOCUMENT IS UNCONTROLLED IN HARDCOPY FORMAT Doc I&NA-CCV-SER-SOP 2196 <br /> SER Date of This Issue: 9/28/2017 Date of Next Review 9/28/2020 Page 3 of 10 <br />
