Small Quantity Generator
Determining Small Quantity Generators
The law says that a small quantity generator is one that generates less than 1,000 kilograms of hazardous waste in a calendar month. RCRA Title 40 Code of the Federal Register (CFR), Part 261 contains lists specifying wastes that are regulated and characteristics for identifying non-listed hazardous wastes.
The unlisted hazardous wastes may be identified as one if it exhibits any of the four characteristics of a hazardous waste:
- Ignitability: The waste material (solid, gas, or liquid) must have a flash point of less than 140°F and/or be an aqueous solution with an alcohol content of greater than or equal to 24%. Examples are solvents, paint thinners, and oxidizers.
- Corrosivity: The waste material must be a liquid and have a pH of less than 2.0 or greater than 12.5. Examples are acids and caustics.
- Reactivity: The waste material is reactive to water, shock, heat, and pressure, and undergoes a rapid violent chemical reaction. Examples are perchlorates, peroxides, and cyanides.
- Toxicity Characteristics (TC): This category includes eight heavy metals and thirty-one organic chemicals including ten pesticides. Waste in this category need only contain very small amounts of arsenic, lead, mercury, or one of the other heavy metals, or organics such as benzene, trichloroethylene, per chloroethylene, vinyl chloride, methyl ethyl keytone, or one of the ten pesticides.
