Hazardous Waste Management System - Identification and Listing of Hazardous Waste - Toxicity Characteristic - Hydrocarbon Recovery Operations - Federal Register Notice, February 1, 1991
On October 5, 1990 (55 FR 40834), the Agency promulgated an interim final rule extending the compliance date of the Toxicity Characteristic until January 25, 1991 for groundwater that is reinjected or reinfiltrated during existing hydrocarbon recovery operations at petroleum refineries, marketing terminals, and bulk plants. Today's action further extends this compliance date until March 25, 1991, in order to allow the Agency sufficient time to fully evaluate comments received on this issue.
