We have three types of outputs for the substances in this compound: shipped as product, shipped as waste (residue cleaned from equipment), and emitted to air. What is the best way to estimate percentages for each output type? r1 fl. t II ANSWER: If you know that a portion of a listed hazardous substance (HS) remains with the product as shipped, provide your best estimate of the percentage of the HS in the product and multiply that by the estimated total pounds of product. Estimate the pounds of waste that were generated and the percentage of the listed HS in the total waste. Multi- ply to estimate the pounds ofHS in the waste. Any remainder HS input is assumed to be emitted to the air. , 1 i r-i Total Inputs = Output shipped as product + Output shipped as waste + Output as air emISSIon . l 21. QUESTION: Suppose we have a mixture containing substances that are not on the list of hazardous substances and the mixture does not meet the definition of a characteristic chemical, yet some of its individual components may be corrosive. If these components do not separate during the manufacturing process, would the corrosive component( s) be considered characteristic? " , ANSWER: No. Characteristic substances in a non-characteristic mixture are not report- able as long as they remain in the mixture -- and the mixture remains non-characteristic -- throughout their life cycle in Eugene. 22. QUESTION: Do we have to double-report chemicals under this act? For example, suppose a mixture is corrosive, and one of the components is reportable. How should the mixture be reported? How would this be reported if the same corrosive substance is also reportable? ANSWER: Double-reporting is explicitly discouraged. In the case of a listed reportable substance that is part of a characteristic mixture, report the listed substance as a specific hazardous chemical. If you do not know whether the remainder of the mixture is corrosive, then the remainder need not be reported. If the remainder is corrosive, but its ingredients are unknown, then the remainder should be reported in the generic "corrosive" characteristic substance category. 23. QUESTION: Some chemicals are included onthe chemical list as a specific isomer and are also included on the list as mixed isomers. For example, o-xylene is on the list, and so is xylene (mixed isomers). How should these types of substances be reported? ANSWER: To avoid double counting, the reporting business will have the option of reporting a substance as either the mixed isomers or as the specific isomer. F-7
