[en] Volume 2 is an integral part of the Office of Environmental Managements (EM's) Waste Management Programmatic Environmental Impact Statement (WM PEIS), which portrays the impacts of EM's waste management activities at each of the 17 major DOE sites evaluated in the WM PEIS. Impacts are displayed for each of the 17 major sites in tabular form as a complement to the impact discussions in waste-type Chapters 6 through 10. The chapters present background information on each waste type, volume data, existing capacities for managing the wastes, and assumptions used in the waste-type analysis. Readers should refer to these chapters and to Chapter 5, ''Impact Analysis Methodologies,'' for a more thorough discussion of the methodologies, assumptions and definitions associated with these impacts. A synopsis of key definitions and assumptions is also presented at the rear of this introductory section
