observations during the inspection and a hand level survey of the depth of the sumps, <br />the sumps have excess capacity plus the following design capacity: <br /> Water Sediment Total <br />East Sump - A-F 0.80 N/A 0.80 <br />West Sump - A-F 0.32 N/A 0.32 <br />The sewage lagoons located at the unit train loadout consist of an aeration lagoon and <br />a series of three non-discharging lagoons. During the inspection, the first lagoon was <br />dry and the second and third lagoons (cells 3 & 4) contained some water. The capacity <br />of the lagoons is not considered important and is therefore not presented. The lagoons <br />are inactive. The embankment on all of the lagoons needs to be graded to smooth out <br />erosional features. Plans are to delay maintenance of the embankments until the <br />sewage treatment system is re-activated. <br />To the best of my knowledge and belief and except as noted above, the impoundments <br />have been maintained as designed~Rd~i~ accordance with the approved plan and <br />applicable regulations. ~s~p4d,o c~<<'~,, <br />eo o- r ~,° <br />~f ,~ ~ z os <br />Jai7~s~. to~Y `° N3 Date <br />-4- <br />
