Page 5 Cont. <br /> be collected from the excavated area in the following <br /> manner: <br /> One composite sample representing each of three berms, i.e. , <br /> one composite sample for the north berm, one for the south, <br /> and one for the eastern berm. Note: composite samples should <br /> consist of a minimum of three discrete samples collected at <br /> differing locations between the toe of the berm (pond bottom) <br /> and the top of the berm excavation (high water level) . <br /> Two composite samples representing the eastern portion of the <br /> pond bottom: one for the southeast quadrant and the other <br /> for the northeast quadrant. The two composite samples should, <br /> at a minimum, consist of three discrete samples collected at <br /> different locations in the respective quadrant. <br /> The North Area trench must also be sampled. One composite <br /> sample consisting of a minimum of three discrete samples <br /> collected at different locations within the trench area shall <br /> be collected and submitted for analysis. <br /> Upon completion of the Phase 2 , excavation activity in the <br /> western portion of the pond, confirmation sampling of the <br /> berms and pond bottom as described above shall be completed. <br /> Sampling locations will be the north, south and west berms, <br /> and the pond bottom. The pond bottom samples will be collect- <br /> ed from the northwest and southwest quadrants. <br /> Note: Adequate portions of the discrete samples used to <br /> formulate the composite samples shall be retained until re- <br /> view of the laboratory report has been completed by the re- <br /> gulatory agencies. " <br /> MCTC response: <br /> These sampling procedures will be incorporated into the <br /> closure construction contract documents. <br /> We look forward to working with the agencies in completing the <br /> closure of the impoundment. If you have any questions or comments <br /> regarding these responses or the planned closure activities, please <br /> contact me at ( 913 ) 362-1818 . <br /> Sincerely, <br /> E MARLEY COOLING TOWER CO. <br /> David W.
