One shows the TCLP results for Solvair still residue. <br /> Another shows the TCLP results for he filter elements from a Solvair system. Also attached are the aquatic toxicity test <br /> results from used filter elements obt ined from a Solvair system and the aquatic toxicity test results for two samples of Solvair still <br /> residue. These samples were obtai ed from Solvair systems processing commercial drycleaning. In reviewing the attached files I <br /> noticed that only the first page of the report for the filter cartridge components were scanned. I will have the remaining pages <br /> scanned and forwarded to you tomo row. <br /> Please note that the filter elements re comprised of metal structural components, pleated paper used to trap insoluble materials, <br /> and activated granular carbon. The ample of paper submitted for analysis included two samples of paper taken from different <br /> sections of the paper element of on cartridge. Likewise, the sample of carbon submitted for analysis was comprised of three <br /> aliquots taken from different areas ir the carbon chamber of one cartridge. Each sample was analyzed independently of the <br /> others. Consequently, the results are reported as if each component represented the entire cartridge. This in turn resulted in <br /> artifically high numbers. The estima ed weight percent represented by the paper and carbon in a single spent filter element are <br /> 54% and 30%, respectively. <br /> These results suggest that the Solve it still residue will not currently meet the requirements of the California non-hazardous waste <br /> characteristics. For the filter elements, however, the results suggest that the spent filter cartridges are non-hazardous. <br /> Please feel free to contact me if you have any questions, concerns, or comments regarding this information. <br /> Best regards, <br /> Tim Racette <br /> Vice President- Research and Dew lopment <br /> Solvair LLC <br /> 184 Shuman Blvd. <br /> Suite 420 <br /> Naperville, IL 60563 <br /> P: 630 416 6221 <br /> 10/20/2008 <br />
