This section also provides separate inventory forms for nonhazardous and hazardous industrial wastes generated at your facility.Key ConceptsIn many countries, facilities are required to submit information regarding the type and amount of waste generated (see regulatory summary Tab 2). Even when not required by law, it is a best practice to maintain an inventory of all the wastes produced. In addition to piling an inventory of each hazardous waste generated, it is important to document how each waste is managed onsite. The primary focus of this work plan is on wastes that pose a substantial threat to human health or the environment if improperly managed. Throughout this work plan, these wastes will be referred to as hazardous As hazardous wastes generally are regulated more stringently than nonhazardous wastes, it is important that you determine whether each waste generated is hazardous or nonhazardous and document the basis for each determination.Unless otherwise prohibited by a regulatory agency, hazardous waste determinations may be performed by applying your knowledge of the waste based on the materials or processes used. In situations where you do not possess sufficient knowledge to determine whether a waste is hazardous, you should collect a representative sample of the waste and submit it for laboratory analysis. In some countries, the methods for laboratory analysis may need to be approved by the national environmental agency. Furthermore, hazardous waste determinations should be repeated whenever process changes are made that might significantly alter the hazardous nature of the waste.If you are not sure whether a waste is hazardous, but suspect that it might be, you should manage it as hazardous waste until analytical data is obtained that confirms the waste is not hazardous. This is a best practice because (1) a hazardous waste may be considered to be hazardous at the point of generation, not when laboratory data confirm that it is hazardous and (2) whatever risk the waste poses begins when it is first produced, not when you eventually determine the hazard is present. 1 The term hazardous waste, as it is used in this work plan, refers to a waste that, because of its quantity, concentration, or physical, chemical, or infectious characteristics, is subject to controls imposed by a regulatory agency. The regulatory agency in your country may use the term “toxic waste”, “dangerous waste”, “special waste”, or another term instead of the term hazardous waste.9 / 167InstructionsPart 1 Plant ProfilePlant profiles and process maps are tools used to identify every step of a process, from the beginning to the end of and operation, and to track where wastes are generated throughout a process. If available, insert a Plant Profile or Process Map behind this Tab. If a plant profile or process map is not available, create an action item in Tab 12 to collect this information. Process maps can be constructed by identifying the original inputs of each process and tracking those inputs to the end of a process (the map should include chemicals added, solid wastes generated, etc.). Plant profiles should indicate the waste stream generation points. This Tab should also be used to reference the location of the following plant diagrams:? Any diagram prepared for the contingency plan and emergency procedures,? Design drawings for waste management units (landfills, waste piles, etc.), and ? Waste management system flow diagrams.Part 2 General DirectionsIf other than kilograms, please indicate the measurement units used when you plete the quantity section of the following forms. Also, please use the waste management codes in Table 1 to indicate how the wastes are managed onsite. Sample copies of all forms are behind Appendix A. 1. Complete Forms 11 and 12, Waste Inventory Summaries, for all wastes managed at the facility. Use Form 11 for hazardous wastes and Form 12 for nonhazardous wastes. Complete Form 13, Waste Profile Sheet, for each waste on the Waste Inventory. Include any obsolete or unwanted chemicals identified during the chemical sweep in the Waste Inventory. Refer to Tab 3 of the Chemical Management Work Plan for details on conducting a chemical sweep.2. The information piled to develop the Waste Inventory and Profile Sheets can also be used in your Pollution Prevention Program (see the Pollution Prevention Work Plan).3. Follow your national or local requirements to determine whether wastes managed at the facility are hazardous wastes (see Tab 2).4. For each waste (hazardous and nonhazardous), use Form 13 contained within this Tab, to document the basis for your hazard determination. This is especially important if you classify a waste based on your knowledge rather than testing. The Chemical Identification and Tracking Form provided in Tab 5 of the Chemical Management Work Plan may be useful for the classification of chemical wastes.5. If your knowledge of the waste is not sufficient to properly classify the waste, you should prepare an action item in Tab 12 to have the waste analyzed for the physical and chemical properties you suspect it may have. Keep a file that contains all supporting analytical data for each waste stream.6. Assign a code to each waste managed at the facility (hazardous and nonhazardous). In many countries, waste codes are provided by the national environmental agency. In addition, waste stream categories are provided in the Basel Convention (see Appendix D of this work plan). If these options do not apply, use the following system to assign a plantspecific code to each waste stream.Model Waste Code System: Three letter plant code (to be assigned by your Business), “HW” or “NW”, for hazardous or nonhazardous wastes, and Three digit number.7.
