PCBs in Building Materials

Remediation Waste from PCB Cleanups

  • Am I required to comply with greener cleanup practices for my cleanup site?

    EPA encourages the compliance with greener cleanup practices for all cleanup projects, and includes adherence to the ASTM Standard Guide to Greener Cleanups as a condition of its cleanup approvals.

    Greener cleanup is the practice of incorporating options that minimize the environmental impacts of cleanup actions in order to incorporate practices that maximize environmental and human benefit. Region’s 10 Clean & Green Policy supports greener cleanup by promoting sustainable technologies and practices in our cleanup programs in order to conserve energy and help our citizens save money.

PCBs in Used Oil

  • What do I do if my oil is contaminated with PCBs?

    If used oil is contaminated with PCBs at a concentration greater than or equal to 50 ppm at the point of generation, the used oil is regulated for disposal.

    If any PCBs at a concentration of 50 ppm or greater have been added to the container or equipment, then the total container contents must be considered as having a PCB concentration of 50 ppm or greater for purposes of complying with the disposal requirements of this part.

    Used oil that contains PCBs with an original source concentration of 50 ppm or greater must be must be disposed at an incinerator, a high efficiency boiler, a chemical waste landfill, or alternate destruction method pursuant to 40 CFR section 761.60. See list of commercially permitted PCB disposal companies.

    Manifest, storage, and record keeping must be followed for authorized disposal. You are responsible for ensuring full compliance with the regulations for Manufacturing, Processing, Distribution in Commerce, and Use of PCBs and PCB Items (40 CFR section 761.20).

Disposal and Storage of PCB Waste

  • Who may use the generic "40 CFR PART 761" ID number?

    40 CFR section 761.205(c)(1) and (c)(2) explain that generators of PCB waste do not need to notify EPA and receive a unique EPA ID unless their PCB waste activities include:

    • Using, owning, servicing or processing PCBs or PCB Items only if they own or operate a PCB storage facility subject to the storage requirements of 761.65 (b) or (c).

    Generators exempted from notifying EPA under 761.206(c)(2) can use the generic ID "40 CFR PART 761" on manifests, records and reports, unless the generator elects to use an EPA ID previously assigned to them under RCRA by EPA or a state.
