California Waste Profile Analysis Summary for TIVIT Precipitate Representative samples of TMT precipitate were Pimephales promelas(fathead minnows). All tests analyzed by a California state-certified laboratory to had 100%survival after 96 hours of exposure to the determine whether or not TMT precipitate exceeded 750,500,and 250 mg/I test concentrations and to the the regulatory TTLC and STLC values for silver. All dilution water controls. Based on these results,the of the silver 7-ILC test results were below the aquatic 96-hour LC,is greater than the established maximum allowable silver TTLC value of 500 mg/kg threshold of 500 mg/I for fathead minnows. of waste. Similarly,all of the silver STLC test results were below the maximum allowable silver STLC value of 5 mg/1. Is the TMT precipitate a hazardous waste because it contains a listed carcinogenic substance above the regulatory threshold? Is the TMT precipitate a hazardous waste because it exhibits one or more of the following characteristics: No. • Acute Oral Toxicity; Basis for Determination: • Acute Dermal Toxicity; • Acute Inhalation Toxicity;or Section 66261.24(a)(7),Article 3,Chapter 11, • Acute Aquatic Toxicity? Division 4.5,22 CCR,contains a list of 16 carcinogenic substances. Wastes that contain any of No. these substances,in a single or combined concentration of 0.001 percent by weight are Basis for Determination: considered to exhibit the characteristic of a listed carcinogen. Regulatory levels for acute oral,acute dermal,acute inhalation,and aquatic toxicity have been established Based on process knowledge,TMT precipitate does by California and are contained in Sections not contain any of these 16 carcinogenic substances in 66261.24(a)(3)through 6626.24(a)(6),Article 3, any amount. Chapter 11,Division 4.5,22 CCR. Acute oral and dermal toxicity testing was conducted, utilizing representative samples of TMT precipitate. In the oral toxicity study,no abnormal clinical signs For Additional were evident at any time during the 14-day observation study and all animals survived to Information please call: termination of the study. Based on this study,the acute oral LD50 for TMT precipitate is greater than the established threshold of 5000 mg/kg for male rats. Similarly,in the dermal toxicity study,no abnormal clinical signs were evident at any time during the 14 day observation period and all animals survived to Kodak termination of the study. Based on these results,the acute dermal LD5n for TMT precipitate is greater than Environmental ( the established threshold of 4300 mg/kg for rabbits. Services Based on process knowledge,acute inhalation testing was not conducted because TMT precipitate is a paste- (716) 477-3194 like solid that has negligible vapor pressure and as such does not pose an inhalation hazard. In addition, Monday - Friday because its physical state is a paste-like solid,TMT precipitate will not become airborne. As a result,no feasible inhalation exposure pathway exists. 8 AM to 5 PM Eastern Time Aquatic toxicity testing was conducted by a California state-certified laboratory utilizing representative samples of TMT precipitate. The test species was August
