Which statement best describes hazardous waste determination as it relates to munitions?

• A. Hazardous waste determination is based only on visual cues
• B. Hazardous waste determination is based on munitions type only
• C. Hazardous waste determination is optional for DoD facilities
• D. Hazardous waste determination considers multiple factors including ignitability, corrosivity, reactivity, and toxicity

Answer: (D)

Hazardous waste determination for munitions rests on applying the EPA’s waste characteristics, not on how something looks or on the munition’s type. The key idea is that a waste is considered hazardous if it exhibits one or more of four characteristics: ignitability, corrosivity, reactivity, or toxicity.

Ignitability means the waste can easily catch fire, typically tested by a flash point below a certain temperature. Corrosivity involves wastes that are very acidic or very alkaline, or that corrode containers. Reactivity covers wastes that are unstable, capable of violent reactions, or that can release dangerous gases or explode under certain conditions. Toxicity uses a leaching test to see if the waste contains certain toxic constituents (commonly metals and some organics) at levels that could contaminate groundwater or soil.

For munitions-related waste, residues from propellants, solvents, metals, and breakdown products can meet these characteristics depending on their composition and how they’re managed. That’s why hazardous waste determination must consider multiple factors rather than relying on appearance or munition type alone.

So the statement that hazardous waste determination considers multiple factors including ignitability, corrosivity, reactivity, and toxicity is the best description.
