<br />Battle Mountain Gold <br />NOPV Abatement Requirements <br />page 2 <br /> <br />BMG will be permitted to operate the processing plant, inciudiing the <br />introduction of unprocessed ore, until the projected tailings quality has <br />been achieved. At that point in time BMG will cease operation, of the <br />plant pending approval to recommence operation by the Division,. <br />Monitoring of cyanide levels within the tailings slurry and liquid shall <br />continue to verify the anticipated decay of cyanide levels following the <br />cessation of the detoxification program, until cessation is ap roved by <br />the Division. <br />The introduction of chemical compounds into the processing circuit to <br />affect an immediate remedy of the tailings cyanide problem cou d <br />potentially create additional problems by amending the chemica <br />constituency of the tailings. The Division cautions BMG that rrt will be <br />held responsible for any unanticipated results of its remedialactions. <br />(5) Leak Detection System Effluent Containment: <br />In the event that Cyanide is identified within the tailings im oundment <br />liner leak detection system effluent, BMG shall design and imp ement a <br />pump and pipeline system to return all effluent to the tailing <br />impoundment for containment. <br />(6> Cyanide Interception, Containment and Remedial Plan; <br />If Cyanide is identified within the leak detection system unde item (5) <br />above, BMG shall develop and submit an interception, containme t and <br />remedial plan for impacted ground water, surface water and soi This <br />plan shall be submitted to the Division for review and approva within <br />ten days following detection of Cyanide in the leak detection system. <br />(7) Amendment of Ore Processing Methodology: <br />BMG's preliminary suspicions of altered metallic ore content, nd the <br />coincidental failure of the designed processing cyanide recove y circuit, <br />are indications that the ore processing methodology currently eing <br />applied by BMG may require significant modification. If BMG d termines <br />it necessary to modify its ore processing methodology, BMG shall submit <br />appropriate permit revision applications to the Division. App opeiate <br />permit amendments, supported by comprehensive analytical resul s and <br />design evaluations, shall be submitted by BMG to the Division or review <br />and approval no later than 45 days following completion of the cyanide <br />detoxification of the tailings areas contents, described in ite (4) <br />above. <br />
