EPA Guidance

Hazardous Waste Management System; Identification and Listing of Hazardous Waste; Petroleum Processing Wastes; Exemption for Leachate from Non-Hazardous Waste Landfills: Final Rule (40 CFR Part 261). This final rule was published February 12, 1999 by the EPA Office of Solid Waste. EPA is temporarily deferring from the definition of hazardous waste landfill leachate and landfill gas condensate derived from previously disposed wastes that now meet the listing descriptions of one or more of the recently added petroleum refinery wastes (waste codes K169, K170, K171, and K172, promulgated August 6, 1998, 63 FR 42110). Pending further study of this issue, this deferral is provided to landfill leachate and gas condensate that is subject to regulation under the Clean Water Act (CWA). EPA is also stipulating that as one condition of this deferral, this leachate may not ordinarily be managed in surface impoundments or otherwise placed on the land after February 13, 2001. See final rule and support materials at http://www.epa.gov/epaoswer/hazwaste/id/petroleum/process.htm

Special Y2K Alert

Prevent Year 2000 Chemical Emergencies (EPA 550-F-99-003). This Chemical Safety Alert was issued by the U.S. EPA Office of Solid Waste and Emergency Response. Alerts are issued when EPA becomes aware of a significant hazard. This Alert raises awareness of the Y2K problem and offers strategies to address it. The paper focuses on contingency planning for unanticipated chemical releases [February 1999, 6 pages]. View or download at http://www.epa.gov/ceppo/y2k.htm.
