On December 3, 1990, PHS-EHD received sample results of samples taken on <br /> May 1, 1990 by LMT of their water borne sludge waste stream. LMT was <br /> hoping to self-certify this waste as non hazardous. <br /> The results of LMT's testing are: <br /> 1. On May 1, 1990, LMT submitted a water borne sludge sample to Cal <br /> Water labs for Soluble Threshold Limit Concentration (STLC)of metals <br /> and ignitability, corrosivity, and reactivity analysis. The results are as <br /> follows: <br /> Sample Results <br /> Ignitability 212°F <br /> Corrosivity 5.5 pH <br /> Reactivity Not reactive <br /> STLC Metals None detected over allowable <br /> levels <br /> 2. A water borne sludge sample was submitted to MEC Analytical Systems <br /> Bioassay Laboratory in Tiburon, California on July 10, 1990 for Fish <br /> Bioassay analysis. The results are as follows: <br /> Fish Bioassay Concentration 250% M/L 750% M/L <br /> Fat Head Minnows Surviving <br /> On the basis of the results, LMT self certified the waterborne sludge as non- <br /> hazardous. The dewatered sludge is presently being transported to Harney <br /> Lane Landfill, Lodi, CA. <br /> 3. On March 11, 1991, LMT submitted a sample of the Air Dry Room Paint <br /> dust sweepings to Weston Labs for Toxicity Characteristic Leaching <br /> Procedure (TLCP) analysis of cadmium (cd) and selenium (se). Results <br /> follow: <br /> Tests <br /> Sample ID TCLP <br /> Air Dry Paint Dust Cd Se <br /> .25mg/l ND* <br /> *Note: Selenium is not detectable ND at 0.50 mg/I the reporting limit was <br /> raised due to interference. The interfering substance is not identified. <br /> 3 <br />
