<br /> <br />The leak detection system should also be measured. Frequ ncy of <br />measurement should depend on the quantity of fluid avails le. <br />Measurement should include an accurate account of the amo nt of fluid in <br />the leak detection system. <br />8. A. Douchane's 11-point Response to J. Pendleton's April 5, 199 Letter <br />c. Appendix IV. <br />-5- <br /> <br />Apr.i'. ~q, r;aZ <br />Mr. Shutt says the water in the ponds is recycled at 100 gpm and <br />therefore it will take 21 days to recycle. However, we v~ere told that <br />the pumps in the collection pond recycle at 350 gpm. Doels this mean it <br />will take 3 times as long to complete the experiments. Afire we looking at <br />six Z1-day cycles as opposed to two 21 day cycles? Thisneeds <br />clarification. <br />Item 2 under modus operandi says a screw conveyor will beiinstalled when, <br />in fact, the operation is dumping the material in by hand.. <br />d. Appendix V. <br />a <br />b <br />c <br />Item 1. <br />The attached work schedule for Tailings Area Security covers only January <br />and February. <br />Douchane says the free cyanide levels have dropped below ~0 ppm in the <br />tailings ponds, but the results are in dispute. I can't 'ee how a <br />security fence around the tailings dam would protect anyo e from <br />anything. This must be a misprint. I cannot support sus ending the <br />wildlife security around the ponds until we are certain o the free <br />cyanide levels and know more about the synergistic effectp of cyanide <br />compounds and WAD copper. <br />Item 3. <br />I support establishing the Practical Quantitation Limits fPQL) and <br />Method Detection Limits (MDL> for each of the sample type6 as recommended <br />by Adrian Smith. <br />I support testing for fewer components in the monthly sam ling than are <br />now tested. However, given all of the other material tha we need to <br />digest, I see no need to consider this immediately. I do not support <br />analyzing only for copper as the key indicator. We have een assured <br />that copper exists only in a small portion of the ore bod and that it <br />will be mined out fairly soon. What happens when copper s no longer a <br />problem? BMG will need to analyze more than cyanide and Topper. <br />Item 6. <br />This item fail; to commit to providing a plan for interce ling, <br />Containing, ans ~eme;~ating impactea ground water, surf ac water and Soil <br />as require:' .. .`n ~~~ "~`:n': letter. <br />
