Projections of mixed waste generation during the next few years indicate that the inventory will increase to about 250,000 m3. This does not include the waste that will require treatment as a result of remediation of closed sites under the Comprehensive Environmental Response, Compensation, and Liability ~ The measure of waste by volume rather than weight is industry practice.

. These codes cover acidic aqueous liquids, pond and other sludges, waste solvents, discarded equipment, discarded protective clothing, paint wastes, used air filters, discarded chemicals, lead shielding, contaminated soil, debris, and many other categories.

Inorganic Sludges Waste water treatment sludges, pond sludges, off-gas treatment sludges, plating waste sludges, and reprocessing sludges constitute this group. OtherInorganic Waste This group includes paint waste (paint chips and solids, paint sludges)

regulations, much of EM's waste inventory has been declared hazardous based on the processes that produced it, or other historical knowledge, but actual analyses are generally not available. Data from MWIR-1995 show that more than 80% of the inventory has been declared hazardous because it is suspected to be contaminated with waste solvents, electroplating and metal treating wastes, or waste from leachate treatment (DOE, 199Sa)

FINDINGS, DISCUSSION, AND RECOMMENDATIONS The committee found that EM's mixed waste inventory is sufficiently characterized that conceptual design of treatment processes and waste form selection can proceed. However, the inventory is insufficiently characterized for detailed engineering design of treatment processes or process optimization.

and international regulatory agencies for many years (IAEA, 19961. EPA is proposing a new risk-based "Hazardous Waste Identification Rule" that would allow waste containing only small amounts of hazardous waste to be removed from its system for regulating hazardous wastes.

MWFA appears to have reasonably good descriptive knowledge about the waste types (e.g., paint waste or pond sludges, and fair knowledge about its radioactivity characteristics (e.g., nucTides present and radiation levels) , but MWFA is lacking specific analytical knowledge about the hazardous chemical content of the waste.

Both characterization and technology development efforts should be pursued. Neither detailed characterization nor robust technology provides the total answer to treatment of the EM inventory.
