Ll <br />Brake Shavings Evaluation - Update <br />Sears Auto Centers m Sacramento, California ierracon <br />January 17, 2012 w Terracon Project No. 80117000 <br />California Code of Regulations, Title 22 §66261.24 — Characteristics of Toxicity as non- <br />hazardous equivalent waste. <br />Findings <br />The findings of this investigation are as follows: <br />Based on the laboratory analytical results, the composite brake shaving <br />samples exhibited various CAM -17 metals concentrations above the <br />laboratory reporting limit: barium, chromium, cobalt, copper, lead, mercury, <br />molybdenum, nickel, vanadium, and zinc. As the detected concentrations of <br />the metals are 10 times the STLC limits, the samples were analyzed for <br />STLC CAM -17 metals to evaluate if the waste stream could be classified as <br />California hazardous waste. <br />Based on the laboratory analytical results, the STLC analytical results <br />reported the following four metals concentrations above the laboratory <br />reporting limit: antimony, barium, chromium, and zinc. The results were <br />compared to California hazardous waste STLC limits. The metals detected in <br />the samples were below the applicable STLC limits, except for total chromium <br />in ARD -1 and SUNR-1. It should be noted that the concentration of total <br />chromium is the sum of the concentration of Cr -III and Cr -VI, and the state <br />STLC level for Cr -III is 560 mg/L. <br />Therefore, in accordance with the state regulations to help evaluate the <br />applicable STLC limits, the total chromium from ARD -1 and SUNR-1 were <br />further classified into Cr -III and Cr -VI. The analytical results for Cr -VI for <br />samples from ARD -1 and SUNR-1 were not detected above the laboratory <br />reporting limit. Therefore, in accordance with the Cr -III STLC Interpretation, <br />RG document #56, dated August 19, 1993, the detected Cr -III concentrations <br />in the samples are below the STLC limits of 560 mg/L. <br />Based on the STLC analysis for the samples collected from ARD -1 and <br />SUNR-1, accompanied with the total chromium concentration of these <br />samples, which were 20 times the TCLP limits, the samples were analyzed <br />for TCLP Chromium to evaluate if the waste stream could be classified as <br />RCRA hazardous waste. The TCLP total chromium concentrations for <br />samples ARD -1 and SUNR-1 are not detected above the laboratory reporting <br />limit. <br />4 <br />
