Hazardous Waste

The purpose of the Hazardous Waste Program is to ensure that all hazardous wastes are properly handled, recycled, treated, stored, and disposed to prevent potential harm to human health and the environment.

Hazardous wastes are any used or discarded materials or manufacturing by-products in any form (liquid, solid, sludge, gaseous) that exhibit the characteristics of hazardous wastes. The four characteristics of hazardous waste are Ignitability, Reactivity, Corrosivity, and Toxicity. Additionally, if a waste is listed under State or Federal regulations, then it is considered a hazardous waste.
