The regulations set standards for the hazardous waste management facilities that treat, store, and dispose of hazardous waste. Read the label. Flammable wastes can create fires under certain conditions. Examples include liquids such as solvents that readily catch fire, and friction-sensitive substances. Corrosive wastes include those that are acidic and those that are capable of corroding metal such as tanks, containers, drums, and barrels.
Reactive wastes are unstable under normal conditions.
Toxic wastes are harmful or fatal when ingested or absorbed. When toxic wastes are disposed of on land, contaminated liquid may drain from the waste and pollute groundwater. Toxicity is identified through a laboratory procedure called the Extraction Procedure Toxicity test. DEQ must also identify the extent of contamination, the associated risks, and alternatives for managing the site, as well as evaluate feasibility and cost. Occasionally, there is an imminent threat requiring an immediate response to dealing with contamination to remove or stabilize the threat.
