Section 383 of the Energy Policy and Conservation Act of 1975 (``EPCA'') directs the Federal Trade Commission (``FTC'' or ``Commission'') to promulgate a rule prescribing test procedures and labeling standards for recycled oil. The Commission is required to prescribe the rule within 90 days after the National Institute of Standards and Technology (``NIST'') reports to the Commission test procedures to determine the substantial equivalency of processed used oil with new oil distributed for a particular end use. On July 27, 1995, NIST reported the relevant test procedures for engine oil, and on August 28, 1995, the Commission published a notice of proposed rulemaking seeking written comment on its proposed labeling standards. In this notice, the Commission announces its final rule.
