PCBs (Polychlorinated Biphenyls)

It's important to clarify that used oil generators typically wouldn't intentionally process PCB-containing materials. PCBs (Polychlorinated Biphenyls) are hazardous and strictly regulated due to their environmental persistence and potential health risks. Here's why:

  • PCB Ban: The manufacture, sale, and use of PCBs were banned in the United States in 1979 due to environmental and health concerns.

  • Legacy Equipment: PCBs were historically used in various electrical equipment like transformers and capacitors. Used oil generators might have such legacy equipment on their sites, but they wouldn't be using PCBs themselves.

Common PCB-Containing Equipment (Potential Source of Contamination):

  • Transformers: Older electrical transformers often contained PCB fluids for cooling and insulation. Leaks from these transformers could introduce PCBs into used oil.

  • Capacitors: Some older capacitors used PCBs as dielectric fluid. Leaks or improper disposal of these capacitors could pose a contamination risk.

Regulations and Safeguards:

  • Used oil generators are required by law to manage their used oil properly to prevent contamination and environmental hazards. This includes following regulations for storage, handling, and disposal of used oil.

  • Facilities with PCB-containing equipment have specific regulations regarding maintenance, leak detection, and proper disposal of the equipment at the end of its lifespan.

Important Points:

  • Used oil generators should be aware of potential PCB risks associated with legacy equipment on their sites and take appropriate precautions to prevent contamination.
