On November 16, 2016, EPA proposed to add a nonylphenol ethoxylates (NPEs) category to the list of toxic chemicals subject to reporting under section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA) and section 6607 of the Pollution Prevention Act (PPA). EPA proposed to add this chemical category to the EPCRA section 313 list because EPA believes NPEs meet the EPCRA section 313(d)(2)(C) toxicity criteria. Specifically, EPA believes that longer chain NPEs can break down in the environment to short-chain NPEs and nonylphenol, both of which are highly toxic to aquatic organisms. Based on a review of the available production and use information, members of the NPEs category are expected to be manufactured, processed, or otherwise used in quantities that would exceed EPCRA section 313 reporting threshold.
