Official Definitions (EPA Website) • Hazardous Waste • A subset of solid wastes that pose substantial or potential threats to public health or the environment and meet any of the following criteria identified 40 CFR 260 and 261: • is specifically listed as a hazardous waste by EPA • exhibits one or more of the characteristics of hazardous waste (ignitability, corrosivity, reactivity, and/or toxicity); • is generated by the treatment of hazardous waste; or is contained in a hazardous waste. http://www.epa.gov/radiation/mixed-waste/mw_pg5.htm
EPA Hazardous Wastes Listed Hazardous Waste: • “F”- listed • nonspecific sources, spent solvents • “K”- listed • specific industries • “P”-listed • acutely hazardous • “U”- listed • unused off-spec Characteristic Hazardous Waste • Ignitability: hazardous because they may ignite, e.g., EPA Haz. No. D001 organic solvents, oxidizers • Corrosivity: liquids like strong acids and bases (D002) • Reactivity: solids that react violently, e.g., picric acid, peroxides, elemental sodium (D003) • Toxicity: based on toxic properties, 8 metals and 32 organic compounds, like As,Hg, PB, Ba,Ag, benzene, chloroform, vinyl chloride.(D004-D0043)
Hazardous Waste Determination • The EPA lists some 400 hazardous wastes. The descriptions are found in 40 CFR Part 261, subpart 261, Sections 261.31-33. • (“F” list, “K” list, “P” list, and “U” list). • Wastes may also be hazardous if they display any of four characteristics: • Ignitability • Corrosiveness • Reactivity • Toxicity (TCLP regulatory levels).
