Transformers that contained PCBs but have subsequently been drained and refilled with a non-PCB dielectric fluid that contains residual PCB concentrations of 50 mg or more of PCBs per kilogram of the fluid.
Commercially formulated PCB liquids drained from PCB equipment or electrical equipment, or PCBs/solvent mixtures obtained through the flushing and rinsing of such equipment.
All other liquid wastes, including solvents and waste oils, which may be described as secondary fuels, that contain 50 mg or more of PCBs per kilogram of the liquid.
Any soil or other loose materials, including absorbents, that contain 50 mg or more of PCBs per kilogram of the solid.
