The measured levels <br />of activity were less than test accuracy for four of the eight tests for <br />filtered brine, four of the eight tests for unfiltered brine, and two of <br />the eight tests for the suspended solids. <br /> <br />Hazardous Waste Analysis <br /> <br />An aliquot of the suspended solids on the Millipore filters was analyzed <br />by Williams Brothers Laboratories for the eight elements specified in the <br />EPA Hazardous Haste Extraction Procedure Toxicity Tests. A copy of the <br />results are attached. <br /> <br />Concen tr a tions <br />considerably <br />removed by <br />wastes. <br /> <br />for each of the eight elements were <br />below the EPA limits. Therefore, the solids <br />filtration are expected to be classified as <br /> <br />very low and <br />which will be <br />non-hazardous <br /> <br />Disposal <br /> <br />The quantity of dry solids to be removed from the brine will be about 250 <br />pounds per month. It is concluded that a hazardous waste management <br />facility will not be required for disposal of these small quantities of <br />filtered suspended solids. <br /> <br />Sincerely yours, <br />Cl . <br />. ..J: <br />.- -!,.' ~ <br />,C<7 '.,...<1' ./1. . <br />" ... 1'. >.~ (J!,...... <br />/.~;......
