PCB-contaminated Oils Are Oils (usually Transformer Oils, Hydraulic Oils, Or Insulating Oils) That Contain Polychlorinated Biphenyls (PCBs) Above Trace Levels.
PCBs Are persistent Organic Pollutants (POPs), Toxic, And Environmentally Hazardous.
Even Low Concentrations Can Be Heavily Regulated.
Regulations Vary, But Typical Thresholds Include:
| PCB Content (ppm) | Classification / Regulatory Status |
|---|---|
| < 50 Ppm | Generally Considered “non-PCB” Or De Minimis, May Be Handled With Standard Oil Disposal Regulations. |
| 50–499 Ppm | “Low-level PCB Contamination” – Regulated, Disposal And Transport Restrictions Apply. |
| ≥ 500 Ppm | “PCB Oil” – Highly Regulated; Disposal Via Approved Incineration Or Chemical Treatment. |
| ≥ 50,000 Ppm (5%) | Highly Toxic, Often Referred To As “pure PCB” Oil. |
