Chapter 5 - Managing Hazardous Waste
Materials are classified as hazardous waste based on the manner in which they are disposed and the hazards their disposal will present to human health and safety, as well as potential environmental damage. For a chemical to become a hazardous waste, it must first meet the regulatory definition of "Solid Waste".
The Environmental Protection Agency (EPA) defines a Solid Waste as any “garbage, refuse, sludge and other discarded material” including:
- Contained gaseous materials
resulting from industrial, commercial, mining, and agricultural operations.
The definition of Solid Waste has more to do with the disposition of the material, rather than the physical state of the material.
