<br />also continue with the approved quarterly full suite <br />analysis for all sites. Copper will be analyzed on a bi- <br />weekly basis until a reduction in sampling frequency is <br />approved. <br />Results of the monitoring will be submitted to the <br />Division accompanied by a summary letter report within <br />three days following receipt of the analyses. <br />(4) TailinQS Cyanide Detoxification: <br />BMG shall develop and submit a plan for cyanide <br />cation of the entire slurry and liquid content <br />tailings impoundment as soon as possible for r~ <br />approval by the Division. This plan shall be sub <br />a technical revision application. This applicat <br />include a schedule for implementation. Following <br />of this technical revision, BMG shall imple <br />treatment method in accordance with the plan. Ap; <br />frequency and distribution of monitoring of the <br />and plant circuit shall be proposed within the ap; <br />and subsequently conducted to verify the proc <br />success of the remedial treatment. Monitoring <br />covered by an appropriate cover letter report <br />submitted to the Division weekly during the detox <br />program. <br />Discussion: <br />Response is attached as "Exhibit E". <br />(5) Leak Detection System Effluent Containment: <br />ietoxifi- <br />s of the <br />:view and <br />Witted as <br />lon shall <br />approval <br />vent the <br />~ropriate <br />tailings <br />ilication <br />ress and <br />results, <br />shall be <br />fication <br />In the event that fluid is intercepted by the tailings <br />impoundment liner leak detection system, BMG sha 1 design <br />and implement an automated system to mini ize the <br />development of hydraulic back pressure within the leak <br />detection system. This system is intended to r duce the <br />likelihood of compromising the secondary cl y liner <br />intercepting and withdrawing leakage. <br />In the event that cyanide is detected within ~he leak <br />detection system effluent, BMG shall design and mplement <br />a containment system to return all effluent to the <br />tailings impoundment in order to prevent impact to the <br />environment. <br />Discussion• <br />The tailings impoundment is a sub-areal thin laye# deposi- <br />tion type impoundment. The tailing deposition; area is <br />drained into a collection pond. The drain fo~ces the <br />
