ABSTRACT
Used oil is considered to be a waste product because it has served its original intended purpose and must be discarded. The notice presents supplemented information gathered by the EPA and provided to the EPA by individuals commenting on previous notices on the listing of used oil and used oil management standards. The EPA intends to amend 40 CFR Section 261.32 by adding four waste streams from the reprocessing and rerefining of used oil to the list of hazardous wastes from specific sources. The EPA noted its intention to include these residuals in the definition of used oil in its November 29, 1985, proposal to list used oil as hazardous. The wastes from the reprocessing and rerefining of used oil include process residuals from the gravitational or mechanical separation of solids, water, and oil; spent polishing media used to finish used oil; distillation bottoms; and treatment residues from primary wastewater treatment.
