2. A solid waste is evaluated for the characteristic of toxicity using the Toxicity Characteristic Leaching Procedure (TCLP) test. If any constituent of a waste is greater than the "regulatory level" for that chemical, as found per TCLP testing, the waste is a hazardous waste under RCRA. (18% - 6 points each) a. Where in the federal regulations (CFR) do you find the requirements for the toxicity characteristic? Be as specific as you can. C.F.R. b. The extract from the sample of waste is tested and contains 75.0 mg/liter of Barium and 2.0 mg/liter of Chromium. These are both metals. Is this a hazardous waste under RCRA because of the toxicity characteristic? Answer yes or no, AND indicate for each of these chemicals whether it is above or below its regulatory level. C. Another substance is tested under TCLP, and the extract from the sample of waste is tested and contains 2.0 mg/liter of tetrachloroethylene and 1.0 mg/liter of vinyl chloride Is this a hazardous waste under the toxicity characteristic? Answer yes or no, AND indicate for each of these chemicals whether it is above or below its regulatory level
