This leads to the creation of negligible amounts of the only PFAS arrowhead substance - trifluoroacetic acid (TFA).5 The respective TFA amounts result in de minimis increases in overall TFA environmental concentrations by comparison with pre-existing TFA levels. 6 7 In this respect, highly qualified independent assessments by UNEP panels have repeatedly concluded that "The current low concentration of trifluoroacetic acid (TFA) produced by the degradation of several hydrofluorocarbons (HFCs) and hydrofluoroolefins (HFOs), is currently judged not to pose a risk to human health or to the environment." 8 and that "available evidence indicates that this breakdown product [TFA] is of minimal risk to human health".9 1 See the list of acronyms and abbreviations (aligned with the Proposal) in Annex I below. 2 1-Propene, 1,3,3,3-tetrafluoro-, EC no: 471-480-0, CAS no.: 1645-83-6, Mol. formula: C3H2F4 3 (1E)-1-chloro-3,3,3-trifluoroprop-1-ene, EC no.: 700-486-0, CAS no.: 102687-65-0, Mol. formula: C3H2ClF3 4 On 22 March 2023, ECHA published the PFAS REACH Annex XV Restriction Report in the Registry of restriction intentions until outcome and started the 1st Annex XV report consultation with a final deadline for comments on 25 September 2023. 5 See SI Table 3 (pages 312-313) and sections SI 4.3.2, SI 4.3.2 (pages 317-318) of the Environmental Effects of Stratospheric Ozone Depletion, UV Radiation, and Interactions with Climate Change, EEAP 2022 Assessment Report. 6 According to the conclusions in Chapter 6, section 3.8 of the Environmental Effects of Stratospheric Ozone Depletion, UV Radiation, and Interactions with Climate Change, EEAP 2022 Assessment Report, respective "releases will add to the existing load of TFA in the environment but predicted amounts are well below the threshold for concern with respect to human and environmental health." 7 See also detailed EFCTC position paper on the topic Published evidence supports very low yield of TFA from most HFOs and HCFOs. 8 Page 9, Environmental effects of stratospheric ozone depletion, UV radiation, and interactions with climate change: UNEP Environmental Effects Assessment Panel, Update 2020 9 Pages 8-9, Summary Update 2021 for Policymakers, UNEP Environmental Effects Assessment Panel 2 The most recent UNEP EEAP 2022 Assessment Report also concludes that "based on projected future use of these precursors of TFA [incl.

Our analysis was prompted by a recent suggestion that uoropolymers should be considered as polymers of low concern (PLC). (3) According to the Organization for Economic Cooperation and Development (OECD), "polymers of low concern are those deemed to have insignicant environmental and human health impacts." (6) The PLC status of a material leads to exemptions for manufacturers from requirements under the legal chemicals management frameworks in some jurisdictions. (7) In recognition of the potential risks posed by PFAS-related polymers, the U.S.
