On March 5, 2021, the U.S. Environmental Protection Agency (EPA) announced that “[i]n support of the Biden-Harris Administration’s commitment to making evidence-based decisions to protect human health, U.S. Environmental Protection Agency (EPA) is taking an important step by proposing the cancellation of the registration of pentachlorophenol.” Pentachlorophenol, a well-recognized wood preservative in use for decades, is registered under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). According to EPA, it is used primarily on utility poles. For more information on the cancellation of pentachlorophenol, please read the full memorandum.
