Answer: Hazardous waste includes acutely hazardous waste, extremely hazardous waste, non-RCRA hazardous waste, RCRA hazardous waste, special waste, and universal waste. PCB wastes are regulated as non-RCRA hazardous waste when PCB concentrations are ≥ 5 ppm in liquids and ≥ 50 ppm in non-liquid wastes.
