Illustrative List of Long-Chain Perfluoroalkyl Carboxylate (LCPFAC) Chemical Substances

EPA is providing the following illustrative list of chemicals as guidance on the LCPFAC category definition described in 40 

CFR 721.10536(b)(1). Table 1 provides examples of chemical substances for each of the five LCPFAC category definition

subgroups. Table 2 provides all of LCPFAC chemical substances that meet the category definition and are recorded in the 

EPA’s Substance Registry System (SRS). However, note that this is not a definitive or exhaustive list of the LCPFAC 

chemical substances described in 40 CFR 721.10536(b)(1). The chemical substances covered by 40 CFR 721.10536 are 

those that meet the chemical formula provided in the regulation.
