  1. A facility plans to thermally treat hazardous waste in a boiler to recover energy. Under what conditions is this considered legitimate recycling rather than sham recycling?

    Answer: The waste must have a heating value of at least 5,000 BTU/lb and be used as a fuel in a boiler

    EPA's legitimacy criteria require, among other things, that hazardous waste burned for energy recovery have a meaningful heating value (≥5,000 BTU/lb) and be used as a fuel.

  2. Which type of hazardous waste storage unit requires secondary containment, leak detection, and a liner under 40 CFR Part 264 Subpart J?

    Answer: Surface impoundment

    Surface impoundments under 40 CFR 264 Subpart K must have double liners, a leachate collection system, and groundwater monitoring.

  3. What is the regulatory status of hazardous waste that has been delisted by EPA?

    Answer: It is no longer subject to RCRA Subtitle C regulation for the specific waste from the specific facility

    A delisted waste is no longer considered hazardous under RCRA for that specific waste stream from that specific facility, removing it from Subtitle C regulation.

  4. Under TSCA Section 6, EPA required phased elimination of polychlorinated biphenyls (PCBs). What is the general disposal standard for PCB concentrations ≥500 ppm?

    Answer: Incineration in an approved incinerator or high-efficiency boiler

    PCBs at concentrations ≥500 ppm must be incinerated in an EPA-approved incinerator or approved high-efficiency boiler under 40 CFR 761.

  5. A TSDF's closure plan must address all of the following EXCEPT:

    Answer: Annual financial audits submitted to EPA

    Closure plans must address waste disposition, decontamination, and financial assurance, but do not require annual financial audits to EPA during closure.

  6. Which RCRA concept determines whether contaminated environmental media (soil, groundwater) at a TSDF is subject to RCRA Subtitle C hazardous waste regulation?

    Answer: Contained-in policy

    The contained-in policy states that environmental media is not itself a listed waste but is subject to RCRA if it 'contains' a listed hazardous waste.

  7. Under RCRA, what post-closure care period is typically required for hazardous waste landfills after final closure?

    Answer: 30 years

    RCRA requires a minimum 30-year post-closure care period for hazardous waste landfills, during which groundwater monitoring, maintenance, and reporting must continue.
