At the above web page, EPA posted a number of documents regarding the CCL5 and PFAS health effects, including the draft SAB reports that are the subject of the July meeting (the links to the draft SAB reports are located at the bottom of the page).

CCL5 – the draft CCL5 was published for public comment in July 2021 and included 66 chemicals, three chemical groups (PFAS, cyanotoxins and disinfection byproducts) and 12 microbial constituents (including virus, bacteria and protozoa). The final CCL5 is expected to be published during 2022. Once the final CCL5 has been published, EPA has five years to make a determination whether to regulate at least five constituents from the list.

PFAS – EPA plans to publish proposed Maximum Contaminant Levels (MCLs) for PFOA and PFOS during fall 2022 and publish final MCLs during fall 2023.
