EPA issued a draft memorandum for public comment that communicates EPA's approach on when and how to consider potential adverse climate change impacts in the PCB approval process under the Toxic Substances Control Act. This memorandum would clarify that, for PCB cleanup, storage, and disposal approvals, our determination of no unreasonable risk is to be inclusive of not only current but future conditions at sites and facilities vulnerable to potential adverse climate change impacts. We identify measures that strengthen the resilience of PCB cleanup, storage, and disposal controls to climate change impacts, ensuring the protection of human health and the environment over time. EPA welcomes comment on the memorandum through 26 January 2024.?
