Doulou OCT 2 91991 <br /> Pae tic Fasergy <br /> 6OSS East Washington Boulevard ENVIRONMENTAL HEALTH <br /> Eighth Floor PERMIT/SERVICES <br /> C.=erre, CA 90040 <br /> SUBJECT; s===7 of Analytical TCLP Data and Comparison to Toxicity <br /> Gharactudstic Regulatory Levels <br /> Dear Mr. Donlou: <br /> Roy F. Weston, Inc. MBSTOn, is pleased to submit this summary of analytical data and <br /> comparison to toxicity characteristic regulatory levels for the "Plant Condensate" sample <br /> collected at Pacific Energy's Stockton Landfill Power Station. As requested, WBSTON has <br /> compared the results of the Toxicity Characteristic Leachate Procedure (TCLP) atsalysis <br /> with both Federal and State regislatory leve as described below. The results reported for <br /> the Plant Condensate sample show that the concentration 1br no regulated substance exceeds <br /> the Federal or State levels for toxicity characteristics. <br /> The Federal Toxicity Cbaracteristic Final'Rule was promulgated by EPA in the Federal <br /> Regfstar on March 20, 1990. The rine revised existing toxicity cbameteristfcs used by EPA <br /> to identify hazardous waste to be regulated under Subtitle C of the Resource Cotswvation <br /> and Recovery Act (RCRA). The tonicity characteristic is one of Four eberaotatietioe used <br /> by EPA to classify hazardous waste. A wasrto is hazardous if analysis of the TCLP extract <br /> contains concentrations greater than or equal to the levels listed for regulated substanoes. <br /> For TCLP analysis. of a liquid waste containing less than O.SOA undissolved solids by wefght, <br /> the method requfivs filtration of the waste through a 0.6 to 0.8 �= glans t'ltar, The filtrate <br /> would be the TCLP extract. <br /> In the State of California,, a waste is hazardous if the concentration for Perdmat and <br /> Dioaccumulative Subetaaca4 exrad Threshold Limit Concentrations as defined in Section <br /> 66699 of Title 22 of the California Code of Regulations (CCR). The Soluble Threshold <br /> Limit Coaceatration (STLQ is determined by performing the Waste Extmctian Test(RET) <br /> in Section 66670 of Title 22. Tho WET method for liquid sample#containing lose than O.S% <br /> undissolved solids by weight states that the sample will not be subject to the WET procedure <br /> and shall be analyzed directly for the aubstar listed in Section 66699. <br /> ie�o�atsS,Tt� <br />
