Technical Summary

Waste is any material that has insufficient value to justify further beneficial use, and thus must be managed at a cost. Wastes that contain hazardous substances, either radionuclides or toxic chemicals, are generated by many human activities. Management and disposal of these wastes must be conducted in ways that protect human health. Because hazardous wastes vary widely in their compositions and concentrations of hazardous substances and in their potential impacts on human health, the need to protect human health is met most efficiently by use of a variety of technological approaches to waste management and disposal, rather than a single approach for all wastes. 

Management and disposal of the wide variety of hazardous wastes has been aided by the development of waste classification systems. The term waste classification refers to broadly defined waste categories related, for example, to properties of waste materials, potential risks to human health that arise from waste management or disposal, or the source of the waste. Ideally, hazardous wastes in the same class should pose similar risks to human health and, thus, require similar approaches to safe management and disposal. 

NCRP emphasizes, however, that waste classification does not provide a substitute for establishing requirements on treatment and disposal of specific wastes at specific sites, requirements on remediation of contaminated sites, or decisions by regulatory authorities about the acceptability of any such activities. The acceptability of particular waste management or disposal activities must be based on site-specific assessments of risks posed by well characterized wastes. Waste classification, although useful, can only inform the process of 

Over the last several decades, separate classification systems have been developed for radioactive and hazardous chemical wastes based on a variety of considerations, the most prevalent being the source of the waste. These classification systems have served their intended purpose of facilitating development of health-protective strategies for waste management and disposal reasonably well. However, they have exhibited a number of shortcomings and undesirable ramifications, which indicate that a new approach to classification of hazardous wastes would be beneficial.

The next level of presentation is a technical summary that gives details of the risks including the system s importance measures systems, effects of data changes, and assumptions that are critical to the conclusions. It details the conduct of the analysis - especially the treatment of controversial points. The last level of presentation includes all of the details including a roadmap to the analysis so a peer can trace the calculations and repeat them for verification.

To address the need of various audiences to understand this Report at different levels of detail, the Report consists of three essentially self-contained parts a short Synopsis, an extended Technical Summary, and the main Report. The Synopsis presents a brief description of the proposed waste classification system, essentially in the form of an overview for legislators and other executive-level decision makers. The aim is to show that the system is simple in principle and concepts, and to illustrate its benefits. The Technical Summary (Section 1) presents an extended discussion of existing hazardous waste classification systems, difficulties with these systems, and the proposed classification system. The aim is to fully describe the proposed system and its rationale and benefits, but without much of the background information on technical and historical details that support the proposal. Many audiences may find that the Technical... 

Summary meets their needs. The main Report (Sections 2 to 8) presents the complete record of this work, without assuming the presence of the Technical Summary.

Under Art. 3, para. 2, of Annex I to PEPAT particular attention is paid to possible flaws in preparing the CEE by requesting a description of the methods and data used to forecast the impacts of the propo.ied activity, as well as an identification of the gaps in knowledge and uncertainties encountered in compiling the information required. This facilitates scrutiny and enquiries from both experts and non-experts, who must be informed on the name and address of the person or organization which prepared the CEE. The latter may also rely on a non-technical summary of the information provided.
