How is transformer oil disposal handled under environmental regulations?

Transformer oil disposal follows hazardous waste and environmental regulations that require oil testing, classification, and approved handling. PCB contaminated oil is strictly regulated and must be treated or destroyed at licensed facilities. Non PCB oil may be recycled or re refined if quality allows. Documentation, manifests, spill prevention, and certified contractors are mandatory. Improper disposal can result in severe penalties, environmental damage, and liability for asset owners.
