Availability of the Systematic Review Protocol for the PFDA, 
PFNA, PFHxA, PFHxS, and PFBA IRIS Assessments

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of public comment period.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is announcing a 45-
day

[[Page 60394]]

public comment period associated with release of the Systematic Review 
Protocol for the perfluorodecanoic acid (PFDA), perfluorononanoic acid 
(PFNA), perfluorohexanoic acid (PFHxA), perfluorohexanesulfonate 
(PFHxS), and perfluorobutanoic acid (PFBA) Integrated Risk Information 
System (IRIS) assessments. This protocol document presents the methods 
for conducting the systematic reviews and dose response analyses for 
these assessments as well as summarizes the Agency's problem 
formulation activities. Public input will help to inform the subsequent 
development of draft assessments for these per- and polyfluoroalkyl 
substances (PFAS) chemicals.

DATES: The 45-day public comment period begins November 8, 2019 and 
ends December 23, 2019. Comments must be received on or before December 
23, 2019.

ADDRESSES: The Systematic Review Protocol for perfluorodecanoic acid 
(PFDA), perfluorononanoic acid (PFNA), perfluorohexanoic acid (PFHxA), 
perfluorohexanesulfonate (PFHxS), and perfluorobutanoic acid (PFBA) 
assessments will be available via the internet on the IRIS website at 
https://www.epa.gov/iris/iris-recent-additions and in the public docket 
at http://www.regulations.gov, Docket ID No. EPA-HQ-ORD-2019-0275. 
Information on these chemicals is provided in the SUPPLEMENTARY 
INFORMATION section of this notice.

SUPPLEMENTARY INFORMATION: 

I. Information on PFAS and Systematic Review Protocols

    Per- and polyfluoroalkyl substances (PFAS) are a large class of 
man-made chemicals widely used in consumer products and industrial 
processes. The basic structure of PFAS consists of a carbon chain 
surrounded by fluorine atoms, with different chemicals possessing 
different end groups. The five toxicity assessments being developed 
according to the scope and methods outlined in this protocol build upon 
several other PFAS assessments that have already been developed, and 
represent only one component of the broader PFAS action plan underway 
at the U.S. EPA (https://www.epa.gov/pfas/epas-pfas-action-plan).
    This protocol document presents the methods for conducting the 
systematic reviews and dose response analyses for assessments of 
perfluorodecanoic acid (PFDA), perfluorononanoic acid (PFNA), 
perfluorohexanoic acid (PFHxA), perfluorohexanesulfonate (PFHxS), and 
perfluorobutanoic acid (PFBA). This includes a summary of why these 
specific PFAS chemicals were prioritized for evaluation, description of 
the objectives and specific aims of the assessments, draft PECO 
(Populations, Exposures, Comparators, and Outcomes) criteria, and 
identification of key areas of scientific complexity. Public input 
received on the protocol is considered during preparation of the draft 
assessments and any adjustments made to the protocol will be reflected 
in an updated version released in conjunction with the draft 
assessments.

any personal information provided, unless a comment includes 
information claimed to be Confidential Business Information (CBI) or 
other information for which disclosure is restricted by statute. Do not 
submit information through https://www.regulations.gov or email that 
you consider to be CBI or otherwise protected. The https://www.regulations.gov website is an ``anonymous access'' system, which 
means EPA will not know your identity or contact information unless you
