  1. Under RCRA, what characteristic makes a material a 'hazardous waste' due to its ability to ignite at relatively low temperatures?

    Answer: Ignitability

    Ignitability is one of four RCRA hazardous waste characteristics, defined by a flash point below 140°F (60°C) for liquids, among other criteria.

  2. What is the threshold planning quantity (TPQ) concept under EPCRA Section 302?

    Answer: The amount of an extremely hazardous substance above which a facility must notify state and local emergency planners

    Under EPCRA Section 302, facilities storing extremely hazardous substances above their TPQ must notify State Emergency Response Commissions and Local Emergency Planning Committees.

  3. What DEQ-regulated document must facilities submit annually to report hazardous chemical inventories above certain thresholds?

    Answer: Tier I or Tier II chemical inventory report

    EPCRA Sections 311–312 require facilities to submit Tier I or Tier II reports annually to state and local emergency planning entities if they store hazardous chemicals above reporting thresholds.

  4. Which designation identifies the most strictly regulated hazardous wastes under RCRA because of their demonstrated harm to human health or the environment?

    Answer: Listed wastes (F, K, P, U lists)

    Listed wastes—designated by the F, K, P, and U lists—are specific hazardous wastes that EPA has determined pose substantial risk, subjecting them to the most stringent RCRA controls.

  5. What is the 'cradle-to-grave' principle in hazardous waste management?

    Answer: Generators, transporters, and disposers all share legal responsibility for hazardous waste from generation to final disposal

    The cradle-to-grave principle holds that generators, transporters, and treatment/storage/disposal facilities all retain legal responsibility for hazardous waste throughout its entire lifecycle.

  6. What is a Safety Data Sheet (SDS) and what role does it play in DEQ chemical regulations?

    Answer: A document providing hazard, handling, and emergency response information for a chemical substance

    An SDS (formerly MSDS) provides comprehensive information about a chemical's hazards, safe handling procedures, and emergency response measures, required under OSHA's Hazard Communication Standard and referenced in many DEQ programs.
