TB followed by a number indicates a chemical or group <br />TB of chemicals appearing on one or more of the Federal lists of <br />reportable substances cited in the Charter Amendment, but without <br />CAS numbers. The TB designator simply takes the place of a <br />CAS number for these chemicals. <br />See Appendix F, <br />Compounds and Mixtures Questions 18 -23 <br />When hazardous substances occur in compounds or mixtures with other and 49 <br />substances, facilities are required to report only the weight of actual <br />hazardous substances. The Safety Data Sheet (SDS) may give the percentage of hazardous <br />substances contained in a mixture or compound, and the weight of each can then be calculated. <br />Otherwise, businesses are expected to use their best engineering judgment and to document it for <br />purposes of audits. <br />Unidentified Chemicals <br />Often a company will know that a substance is reportable because it See Appendix F, <br />Question 25 <br />possesses one of the characteristics of hazardous waste as defined in 40 <br />CFR Part 261, but the company will not know the identity of the <br />chemical (usually because it is a trade secret of the supplier). These chemicals should be reported <br />in the appropriate generic category (C1 through C7). <br />Occasionally, a chemical will be listed on an SDS under a generic name and, instead of a CAS <br />number, a phrase such as "SARA 313 Reportable" is used. When specific chemical identity <br />information is not available, but you have information indicating that a substance is reportable, <br />provision is made to report the chemical in a generic category with the chemical identifier SG in <br />lieu of a CAS number. <br />For example, the generic name "chlorinated aromatic" is listed as an ingredient /component on <br />the SDS. If your facility uses 20,000 pounds of a solvent that contains 80% "chlorinated <br />aromatic," you know that you have used 16,000 pounds of a reportable hazardous substance. <br />You would report the substance as SARA Generic, which appears on the City's list of reportable <br />substances along with the chemical identifier SG. <br />Radioactive Materials <br />Companies must report the identity of radioactive materials for which they have inputs above 1 <br />gram (0.0022 pounds), and must report the amount of input for radioactive substances whose <br />input exceeds 2.2 pounds. Materials accounting, including all four inputs and all 11 outputs, is <br />not required for radioactive substances. <br />Exception: Sealed source radioactive materials, as defined by OAR 333 -100- 055(71), contained <br />in smoke detectors, survey equipment, and small laboratory testing equipment, are not required <br />to be reported. <br />Articles <br />For purposes of reporting under this program, the Toxics Board has See Appendix F, <br />defined "article" as: a solid manufactured item which remains solid Questions 1 -17 <br />14 <br />
