Hazardous Waste in Idaho

Hazardous waste has properties that make it dangerous or potentially harmful to human health or the environment. Hazardous wastes can be liquids, solids, contained gases, or sludges. The wastes can be by-products of manufacturing processes, discarded commercial products, or unused chemicals such as cleaning fluids or pesticides. Businesses that generate waste must determine if their wastes are hazardous.

Hazardous waste is regulated under the Resource Conservation and Recovery Act (RCRA) Subtitle C. Idaho incorporates these regulations into the “Rules and Standards for Hazardous Waste” (IDAPA 58.01.05).

DEQ ensures compliance by inspecting businesses that generate hazardous waste and, if necessary, taking enforcement action. DEQ also assists businesses through compliance assistance, education, and outreach.
