<br />Battle Mountain Gold <br />NOPV Abatement Requirements <br />page 4 <br />analytical results from samples collected from well M-9 have nit detected <br />any Cyanide occurrence. <br />The Division directs BMG to reevaluate its approved program fo ground <br />water monitoring, sampling and analysis for the tailings dispo al area. <br />At a minimum the Division believes that an expanded monitoring program, <br />including additional ground water monitoring wells, should be implemented <br />to ensure continuous penetration of the ground water table. F rther, the <br />Division believes that all tailings area monitoring facilities should be <br />sampled monthly and the analytical results reported expeditiously to the <br />Division. This evaluation report shall be submitted to the Di ision as a <br />technical revision prior to May 29, 1992. <br />Further, BMG shall develop and submit a tailings effluent leak ge <br />interception, containment and treatment plan, to be implemented in the <br />event of contaminant migration from the tailings area. This c tingency <br />response plan should specify methods to remedy contamination of ground <br />water, surface water and soil. This plan shall be submitted to the <br />Division as a technical revision prior to June 15, 1992. <br />Status: Satisfied - BMG has committed to development of remedial plan <br />in letter of April 16, 1992. <br />- The requirements for monitoring plan modif'cation <br />were only advanced by the Division on April 21, 1992. <br />- BMG verbally committed to modify the monitoring plan <br />on April 22, 1992. <br />Deadlines: Submit evaluation report of existing tailings area round <br />water monitoring plan with proposed modifications t the <br />Division by May 29, 1992, as a technical revision. <br />Submit contingency leakage response plan to the Div~sion by <br />June 15, 1992, as a technical revision . <br />(7) Modification of Ore Processing Methodology: <br />BMG's preliminary suspicions of altered metallic ore content, a d the <br />coincidental failure of the designed processing cyanide recover circuit, <br />are indications that the ore processing methodology currently b ing <br />applied by BMG may require significant modification. If BMG de ermines <br />it necessary to modify its ore processing methodology, BMG shal submit <br />appropriate applications to the Division. Appropriate permit <br />modifications, supported by comprehensive analytical results an design <br />evaluations, shall be submitted by BMG to the Division for revi w and <br />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 />
