Today's direct final rule eliminates errors and clarifies ambiguities in the used oil management standards. Specifically, this rule clarifies when used oil contaminated with polychlorinated biphenyls (PCBs) is regulated under the used oil management standards and when it is not, that the requirements applicable to releases of used oil apply in States that are not authorized for the RCRA base program, that mixtures of conditionally exempt small quantity generator (CESQG) wastes and used oil are subject to the used oil management standards irrespective of how that mixture is to be recycled, and that the initial marketer of used oil that meets the used oil fuel specification need only keep a record of a shipment of used oil to the facility to which the initial marketer delivers the used oil. Today's rule also amends three incorrect references to the pre-1992 used oil specifications in the provisions which address hazardous waste fuel produced from, or oil reclaimed from, oil bearing hazardous wastes from petroleum refining operations. The U.S. Environmental Protection Agency (EPA) is issuing this regulation as a direct final rule. In the Proposed Rules section of today's Federal Register, EPA is proposing identical amendments and soliciting public comment on them.
