Table 8.1. Waste Types(a) (continued)
Solid waste, not specifically excluded from regulation under 40 CFR
261.4 (EPA, 1994a), or delisted by petition, that is, either a listed
hazardous waste (see 40 CFR 261.30 - 261.33) or waste exhibiting
Any other hazardous waste not specifically regulated under
TSCA or RCRA, which may be regulated by a State of Local
authority. An example of such waste is used oil.
Hazardous chemical wastes, both liquid and solid, containing more
than 50 parts per million of polychlorinated byphenyls.
Definitions from DOE/S-0101, U.S. DOE Annual Report on Waste Generation and Waste Minimization
Progress, 1991-1992, February 1994 (DOE, 1994o).
In addition to being classified by type, as discussed above, wastes are classified by
treatability group, depending on the treatment the waste receives. The common
treatability groups are defined in Table 8.2. These are reported in each site's annual
waste management report.
Table 8.2. Treatability Groups
Contact-handled LLW: exposure rate of 200 mR/h or less on contact
Remote-handled LLW: exposure rate greater than 200 mR/h on contact
Contact-handled TRU: exposure rate of 200 mR/h or less on contact
Remote-handled TRU: exposure rate greater than 200 mR/h on contact
Mixed Waste (MLLW and MTRU)
Treatable mixed waste has an existing treatment that will eliminate or encapsulate (TCLP) the
hazardous constituents of the mixed waste, rendering it LLW or TRU. Treatable includes
treatment of mixed waste that results in volume reduction.
Non-treatable: no treatment exists
Plutonium facilities generate mostly contact-handled TRU waste (even though they
may do much of the handling and processing within glove boxes for contamination
control). The most common treatment will be compaction although some facilities
have incinerators available.
