Mr. Ed Brosseau - 3 - July 23, 1985 <br />deposition of carried sediment. The main upland ditch had minor <br />sloughing but, in general, would carry design flow. The main road into <br />the site diverts drainage toward the heap pit. It was discussed that <br />drainage needed to be controlled at this location also. See <br />Recommendation No. 2. <br />6. The heap pit liner is non-reinforced Hypalon (?). <br />needs to be reinforced. Anchoring of the liner is <br />locations and slipping and sloughing has occurred. <br />in this report, the liner is not completely instal <br />corner. It was discussed that this work should be <br />Recommendation No. 3. <br />Generally, Hypalon <br />poor in most <br />As mentioned earlier <br />led in the southeast <br />completed. See <br />7. In general, the site has not been constructed with concern for good <br />engineering practice. Maintenance was occurring at the time of this <br />inspection but was occurring inefficiently due to equipment problems. <br />Mr. Brosseau stated that the equipment will be repaired quickly in order <br />to perform required maintenance. <br />8. Expansion of the heap was briefly discussed. Mr. Brosseau stated that <br />he planned to extend the heap up the slope to the north. This slopes at <br />approximately 25 degrees. The inspector stated that a geotechnical <br />analysis would be required for this expansion. <br />9. No cyanide drums or barrels were on the site at the time of this <br />inspection. It was discussed that no further cyanide or solution should <br />be added to this system until adequately reconstructed and repaired. <br />See Recommendation No. 4. <br />10. The Division and the Board appreciate Mr. Brosseau's cooperation during <br />this inspection. See Recommendation No. 5. <br />RECOMMENDATIONS: <br />1. Take additional soil samples to determine if cyanide levels are <br />decreasing. Samples should be taken by July 20, 1985. Results should <br />be submitted to the Division as soon as possible after results are <br />received. <br />2. Grade and/or berm the area above the agglomerator and berm the southeast <br />corner of the heap pit berm to divert drainage away from the heap leach <br />pit site. This work should be accomplished prior to July 20, 1985. <br />
