Solid waste, not specifically excluded from regulation under 40 CFR 261.4 (EPA,

RCRA (USC,

1976a) Regulated

CFR 261.30 - 261.33) or waste exhibiting hazardous characteristics.

8.1.2 Treatability Groups

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

LLW

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

TRU

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
