# SUPPLEMENTARY INFORMATION:

                    There have been two previous Public Comment periods for the Perfluoroalkyls toxicological profile, one in 2009 (74 FR 36492) and 2015 (80 FR 53157). Due to the public comments                           ( print page 32666)                        received to both notices, as well as new literature, we revised the previous draft profile (including a revised Minimal Risk Level (MRL)); therefore, on June 21, 2018, ATSDR released a revised draft profile for public comment (83 FR 28849). Because the substantive revisions were limited to the MRLs Appendix, and given the public health demand for the updated toxicological profile, we opted for a 30 day comment period. ATSDR has received requests to extend the comment period for this profile. Accordingly, ATSDR is extending the comment period an additional 30 days. Comments must be submitted by August 20, 2018.
