This action responds to public comment on two proposals (57 FR 7636, March 3, 1992, and 57 FR 21450, May 20, 1992) to modify EPA's hazardous waste identification rules under the Resource Conservation and Recovery Act (RCRA).
Because of the large number of comments received by the Agency and the need to evaluate all of the technical information provided by the public, EPA is today removing the April 28, 1993 expiration date from its reinstatement of the "mixture" and "derived-from" rules published on March 3, 1992 (see 57 FR 7628).
This action will assure continuity of the existing national hazardous waste program while EPA determines the most appropriate approach for modification of the rules.
