<br /> <br />it will not leave the soil liner uncovered awaiting test <br />results. Therefore, the soil liner will be constructed without <br />ensuring a 10-6 permeability. In order to protect against <br />cyanide releases to the environment, the secondary liner should <br />be constructed of a synthetic geomembrane as suggested by MLRD. <br />B. The HDPE Liner Must Be Anchored And Repaired As <br />Necessary. <br />MLRD suggested that the 60 mil HDPE liner must be <br />anchored in Point No. 30. Not only must the HDPE liner be <br />anchored, but a quality assurance and quality program must be <br />instituted, not only when the liner is installed, but <br />periodically throughout the life of the heap leach to ensure that <br />the HDPE liner is not breached or torn by the earth moving <br />equipment. <br />C. The <br />rclaim With A <br />MLRD's Point No. 37 requested additional information <br />regarding whether the secondary recovery leak detection system <br />and riser pipe for secondary recovery and leak detection sumps <br />will be underlying the entire heap leach or whether these will be <br />centralized within certain areas. Battle Mountain responded the <br />secondary recovery system will only address three areas: the <br />leach pad leak detection sump, the barren pond leak detection <br />-15- <br />
