Explanation
PCBs were widely used in electrical transformers, capacitors, hydraulic fluids, and some building materials (caulk, paint) until banned under TSCA in 1979 due to toxicity. In Nevada, PCBs may be present in older commercial and industrial buildings, particularly in electrical equipment rooms. PCB disposal and cleanup is regulated by the EPA. Commercial property buyers conducting due diligence should include PCB assessment in their environmental review for pre-1979 industrial/commercial properties.
