Hazardous Waste Classification
Waste is considered regulated hazardous waste if it meets any of the following:
- On the F-list (non-specific source waste) See F-List Hazardous Wastes.
- On the P-list or U-list (discarded commercial chemical products) See P & U-List Hazardous Wastes
- Exhibit any characteristic of hazardous waste as described below (ignitable, corrosive, reactive, toxic)
Waste is regulated as hazardous if it meets any of the following characteristics.
- A liquid with a flash point less than 60 degrees Centigrade
- A solid capable under normal conditions of causing fire through friction, absorption of moisture or spontaneous chemical changes
- A flammable compressed gas
- An oxidizer
- An aqueous with pH less than or equal to 2, or greater than or equal to 12.5
- A liquid that corrodes steel at a rate greater than 0.250 inches per year at 55 degrees Centigrade
- Is unstable and readily undergoes violent change without detonating
- Reacts violently with water
- Forms potentially explosive mixtures with water
- Upon mixture with water generates toxic gases, vapors or fumes
- Generates toxic gases, vapors or fumes at pH conditions between 2 and 12.5
- Capable of detonation or explosive decomposition
- Classified as a Department of Transportation explosive
Hazardous: Toxicity Characteristic
- The waste contains certain metals, pesticides or selected organics above specified levels. See List of Toxic Characteristic Wastes.
- if it is otherwise capable of causing environmental or health damage if improperly disposed (this judgment is based on knowledge of the material).
