How does a hazardous waste differ from non-hazardous waste under RCRA?

• A. Hazardous waste is defined by its color; non-hazardous is not.
• B. Hazardous waste is regulated only by state rules.
• C. Hazardous waste is regulated under Subtitle C with stricter handling, storage, and disposal requirements; non-hazardous waste is not subject to those rules.
• D. Hazardous waste is regulated under Subtitle D only.

Answer: (C)

Understanding how RCRA treats wastes helps clarify the difference. Hazardous waste is defined and regulated under Subtitle C, which imposes strict cradle-to-grave management of the waste. This means identifying and classifying the waste, tracking its movement with a manifest, and applying stringent requirements for handling, storage time limits, treatment standards, and disposal, along with emergency preparedness and worker training. Non-hazardous waste does not fall under these Subtitle C rules, so it isn’t subject to those same strict federal requirements; it’s typically regulated under state programs or under Subtitle D as municipal or non-hazardous solid waste. The other options miss the essence: color isn’t a basis for regulation, and hazardous rules aren’t limited to state rules or to Subtitle D.
