CQUalex <br /> Date: April 27, 1999 <br /> To: Qualex HSE Coordinators <br /> From: Michael Stark, Corporate HSE Specialist <br /> Subject: Analysis of Processor Filters <br /> We recently submitted spent film and paper processor filters to be analyzed by certified <br /> labs in two different locations to ensure that the filters were not classifiable as hazardous <br /> wastes and therefore not disposable as solid waste. <br /> The federal Toxic Characteristic Leaching Procedure (TCLP)was performed on used C- <br /> 41 film processing fixer fitters and used RA 100 paper processing bleach-fix filters from <br /> our plants in Washington State and Connecticut. All tests produced leachable silver <br /> concentrations of less than 5 mg/L, which is the concentration at which the material <br /> would be regulated as a hazardous waste. <br /> The Chehalis, WA plant results also show the analysis performed on a treatment system <br /> TMT filter, which also showed leachable silver at less than 5mg/L. <br /> Please file this data so that it may be made available to interested parties. <br />
