The pretreated water is subsequently passed <br /> through the existing ion exchange water treatment plant to reduce remaining <br /> wood treating chemicals in conformance with the requirements of the NPDES <br /> permit. The recovered wood treating chemicals (copper and chromium) will <br /> be reused in the wood treating process. <br /> The sludge generated from the pretreatment process will contain low <br /> concentrations of arsenic and be discharged to the existing Sludge Drying <br /> Beds. The sludge will continue to be sampled and analyzed for hazardous <br /> constituents and disposed of at an approved disposal site. <br /> If you have any questions regarding this information, please do not <br /> hesitate to contact me (913-339-7046) . <br /> Very truly yours, <br /> BLACK & VEATCH <br /> Thomas A.
