a = <br />Documents No. 2 and 3.. Cyanide Detoxification <br />1. Based upon the current studies and testing, does it appear <br />that these processes will allow the existing tailings to be <br />detoxified to the standards established in tk~~e original <br />permit? <br />2. How will treatment of the ponds with the hydrogen peroxide <br />process reduce WAD cyanide levels of the tailings in the <br />impoundment outside of these surface ponds? How wall testing <br />of slurry and liquids outside of the surface ponds be <br />undertaken? <br />3. Some explanation of the lab QA/QC process and data sheets <br />in the ASCI Report would be helpful in interpreting the <br />results. <br />4. What means of testing, (sample locations, sa ple media, <br />lab procedure) will be used to ultimately deter~ine if the <br />tailings have been brought into compliance? <br />5. What bearing, if any, does the ASCI Report have on the <br />analytical protocols recommended by Halapaska in Dbcument No. <br />1? <br />We appreciate this opportunity to comment on the documents <br />provided. <br />If you have any questions on these comments, gleasje feel free <br />to contact our office. ~~ ~ '~ <br />Res~~tfully <br />P.G. 5021 <br />f <br />
