To conserve energy and natural resources. To reduce the amount of waste generated, including hazardous waste. To ensure that wastes are managed in an environmentally sound manner. 8  Resource Conservation and Recovery Act (RCRA), 1976 Gives EPA the authority to control hazardous waste from the "cradle-to- grave." Deals with current and future waste disposal. 9 Hazardous Waste 10  Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) SUPERFUND 1980 Designed to remedy the mistakes in hazardous waste management of the past. 11 12 13 14 15  Hazardous and Solid Waste Amendments (HSWA) Phase out land disposal of hazardous waste 1984 Comprehensive underground storage tank program Increased EPA enforcement authority 16  Superfund Amendment and Re- Authorization Act (SARA) Re-authorized $ for abandoned site clean-up 1986 OSHA to establish safety and health standards for hazardous waste operations and emergency response Three Sections (Titles I, II and III) 17  Resource Conservation and Recovery Act (RCRA) Recovery Disposal Generation Transportation Treatment “Cradle to Grave” Management of Hazardous Waste 18 Hazardous Waste Classification Is the waste a solid waste? Is the waste excluded? Is the waste listed? Does the waste display a characteristic? Is the waste a regulated mixture? 19  Hazardous Waste Characteristics Ignitability Corrosivity Reactivity Toxicity 20 Characteristics of a Waste ! Ignitable Flash point < 140oF Examples: Acetonitrile, alcohols, acetone, toluene, xylene, ether, other 21  Characteristics of a Waste ! Corrosive pH < 2.0 or pH > 12.5 Examples: Acids, glass cleaner, hydroxides, bases, drain cleaners, other 22 Characteristics of a Waste ! Reactive Unstable and may explode under certain conditions such as heat, friction or pressure Examples: Picric acid, peroxide forming chemicals, ethyl ethers, dinitro compounds, other 23 Characteristics of a waste ! Toxic Fails Toxic Characteristic Leaching Procedure (TCLP) Test Examples: Heavy metals: mercury, lead, silver, chromic acid, other 24 Hazardous Waste 25  The “Mixture Rule” A MIXTURE of a HAZARDOUS WASTE and a SOLID WASTE is hazardous if: Mixture exhibits characteristics Hazardous waste is a listed waste Hazardous Solid Waste Waste 26  Mixture Rule 40 CFR 261.3 (a) (iv) What happens if you mix a listed hazardous waste with any other solid waste? 27  Mixture rule answer The entire mixture becomes subjected to regulations as hazardous waste EXAMPLE 1 quart of spent methylene chloride (F002) + 500gallons of used oil = 500.25 gallons of hazardous waste 28 THE Absolute FOUR Things you need to stay out of trouble: Words “Hazardous Waste” Completed Waste Tag (No Abbreviations) Keep Container Closed (Except When Actively Adding) Training (Initial and Annual Refresher)  Hazardous Waste Containers Liquids – EHS provides 5-gallon carboys that DOT-approved – No lab glassware, beakers, flasks Small Containers (< 1 gallon) – Make your own - Deface previous labeling – EHS will bring packing material (boxes, absorbent) and package the wastes for transportation. Examples of HW Containers  Attach to container!!

Liquid, Solid or Gas that is a: – Listed Discarded Chemical Commercial Product (DCCP) – Listed Hazardous Waste (spent from a process/source) – Characteristic Hazardous Waste Discarded Chemical Commercial Product (DCCP)
