Mixed Waste – Hazardous Waste Radioactive Waste NUCP 2311

Mixed Waste Waste that contains both radioactive and hazardous components. Dual regulatory framework – Hazardous: Resource Conservation and Recovery Act (RCRA) Environmental Protection Agency (EPA) OR Authorized States – Radioactive: Atomic Energy Act US Nuclear Regulatory Commission (NRC) OR NRC Agreement States OR US Department of Energy (self regulating) RCRA takes precedence over the AEA when the policies are inconsistent.

What is Hazardous Waste?

Definition – Solid Waste

Waste

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:solid wastes 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.

WHAT IS A HAZARDOUS WASTE? Hazardous by EPA Listing* Under the Resource Conservation and Recovery Act (RCRA), and defined in 40 CFR 261 (Code of Federal Regulations), a solid waste that, because of quantity, concentration, or physical, chemical, or infectious characteristics: (a) causes or significantly increases mortality or serious irreversible or incapacitating reversible illness, or (b) poses a substantial present or potential hazard to human health or the environment when improperly managed. About 400 wastes are listed. EPA also regulates certain materials mixed with hazardous waste regardless of the percentage, and those derived from hazardous waste. Examples of derivatives are: sludges, residues, or ashes. *State and local regulations may also apply

WHAT IS A HAZARDOUS WASTE? Hazardous by Characteristic* Toxic Poisons, mutagens, carcinogens, controlled substances, dyes, stains, mercury and other heavy metals.. Reactive Sulfides, cyanides, explosives, substances that react violently with air, water and/or produce toxic gas or vapors Corrosive Strong acids, strong bases, peroxides. Ignitable Liquids – acetone, toluene, most solvents; Gasses - hydrogen, methane, ethylene; Solids - aluminum powder, nitrocellulose. Oxidizer Diethyl ether, inorganic peroxides, nitrate compounds. Silver Containing Photo fixer, developer, x-ray film. *Including paper and rags used to clean spills.

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 – (“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).
