Residential soils
Residential soils require removal and on-site disposal of surface soil with PCB concentrations greater than or equal to 1 mg/kg, and removal and off-site disposal of subsurface soil with PCB concentrations greater than 10 mg/kg.
High-activity properties
For high-activity special use properties, the EPA requires removal and on-site disposal of surface soil with PCB concentrations greater than or equal to 1 mg/kg, and removal and off-site disposal of subsurface soil with PCB concentrations greater than or equal to 10 mg/kg.
Low-activity properties
For low-activity special use properties, work includes the removal and off-site disposal of surface soil with PCB concentrations greater than or equal to 1 mg/kg and removal of 97 mg/kg at the subsurface.
Soil management
Long-term management is needed for properties with PCBs greater than or equal to 1 mg/kg, for properties with PCB soil concentrations greater than or equal to 1 mg/kg that aren't suitable for removal, and for properties that may have PCBs under a structure.
