Attachment B. Input Types The law specifies four different types of inputs of hazardous substances: 1. Inventory at the facility at the beginning of the accounting period: Report the quantity of each substance that is on-site on January 1 in purchased or manufactured condition. This does not include the quantity of a substance that is For each considered waste waiting for treatment or disposal (see input type 2). substance, this amount should be the same as the amount reported in Output Type 11 (inventory at the facility at the end of the accounting period) for the previous year. 2. Waste stored at the facility at the beginning of the accounting period: Report the quantity of the substance that is on-site on January 1 that is waste. This is the portion of the substance that has been used in a manufacturing process and is For each substance, this amount should be waiting for treatment or disposal. the same as the amount reported in Output Type 4 (waste stored at the facility at the end of the accounting period) for the previous year. 3. Quantity produced at the facility: Report the total quantity of the substance produced by chemical processes on-site during the calendar year. The total quantity includes material prepared in a production process whether as a final product or as an isolated intermediate, and quantities generated as waste that were not stored on-site on January 1 (Input #2). The quantities produced as transient, non-isolated intermediates should not be reported. 4. Quantity brought to the facility: Report the total quantity of the substance brought into the facility from all off-site suppliers, including other facility locations and divisions of your own company, during the calendar year. Output Types The law specifies 11 different types of outputs of hazardous substances: 1. See Appendix F, processes: Chemically altered, or consumed, means Questions 50 and 52 altered in manufacturing processes must be accounted since they represent a reduction of the quantity present. Reportable substances generated during chemical alteration of another substance must be reported as inputs of type 3 in the section above. Transient intermediates, those compounds that are produced and then fully consumed in a continuous process, even if on the list of reportable hazardous substances, are not reportable. Businesses may choose average yields of reactions performed at the facility for the purposes of calculating quantities chemically altered, and apportioning the product to other output types, e.g., between product and waste. - 17-
