time . The sludge removed was deposited in "Failings Pond No. 3 <br /> until ice build-up reduced the pond freeboard to the point where <br /> additional sludge could not be added. Tailings Pond No. 4 was <br /> then used for deposition during the remainder of the cleaning <br /> process. No adverse effects on water duality were noticed as a <br /> result , and a comparative analysis (DPTA extract) of Tailings <br /> Pond No. 4 slimes and AT sludge was done (see Appendix ) for <br /> metals and ABP. Metal analysis was similar to the tailings <br /> slimes and the ABP was positive , which should actually buffer the <br /> ABP of the tailings . <br /> The rock dump for waste material (:mentioned in the 1987 Annual <br /> Report) was not completed , as not enough waste material will be <br /> removed from the mine in the near future to justify its expense . <br /> Activities planned for 1989 are: <br /> (1 ) to continue Pond cleaning on an as-needed basis to maintain <br /> solid settling capacity; <br /> (2) to do site clean-up work; <br /> (3) to install a settling pond piping system that will allow <br /> pond cleaning without disrupting water quality and to reduce <br /> turbulence at the pond inlets; <br /> (4) to install a seepage catchment line to better monitor the <br /> effect of the waste dump on water duality. <br /> Terry Tunnel Area - Plate No. 2 <br /> All trash accumulated at the site was cleaned up and removed from <br /> the site. <br /> The 2 , 000-gallon diesel tank mentioned in the last annual report <br /> was removed from the site as it was no longer needed because a <br /> pumping system was installed underground to service the upper <br /> levels . <br /> The No. 1 settling pond was thoroughly excavated with an <br /> excavator and an impermeable layer was placed and compacted to <br /> stop pond seepage . The sludge excavated was hauled by dump truck <br /> to Tailings Pond No. 3 . Settling Pond No. 2 was partially <br /> cleaned with the mudcat and 80-barrel tankers . The No. 2 pond <br /> was not thoroughly cleaned because the weather was too cold to <br /> compact an impermeable layer and the pond would lea}: if cleaned <br /> completely. The sludge previously deposited in pits at the site <br /> was excavated with an excavator and hauled with dump trucks to <br /> Tailings Pond No. 3 . This was done in agreement with the MLRD <br /> that disposal at the site was not covered under the Permit. <br /> The weir for measuring discharge volume was reset to accurately <br /> measure flow at the site. <br /> - 2 - <br />
