MERCURY Target The D009 category means the waste exhibits a TCLP mercury leachability of greater than 0.20 mg/L. Treatment using standard mercury absorbents is generally accepted, provided the total mercury concentration within this waste is below 260 mg/L. If mercury concentrations are above 260 mg/L, however, EPA regulations currently specify that mercury must also be removed from the waste, using retorting or incineration to support mercury recycling. The waste in the V-9 tank was far above this limit of 260 mg/kg. Inorganic Mercury Untreated Waste Concentration mg/kg 15,700 Table 1. Mercury concentration for untreated waste in V-9 tank.

Therefore, these processes were not deemed acceptable for general use at that time, leaving only incineration or retorting available as acceptable processes.[3] While the existing LDR treatment requirement for radioactively contaminated D009 waste containing greater than 260 mg/kg of total mercury was RMERC or IMERC, the EPA also stated that neither technology was appropriate to apply to radioactively contaminated waste like the V-9 wastes. The agency’s reasoning was that the recovered mercury still would be radioactively contaminated. Since there is no known use for the recovered radioactively contaminated mercury, these technologies were considered inappro- *F001-listed contaminants Table 2.
