Notice of Availability of Draft Guidelines for Human Exposure 
Assessment: Extension of Public Comment Period

AGENCY: Environmental Protection Agency (EPA).

ACTION: Extension of public comment period.

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

SUMMARY: On January 7, 2016 the U.S. Environmental Protection Agency 
(EPA) announced the release of the external review draft of 
``Guidelines for Human Exposure Assessment'' for public review and 
comment (81 FR 774-775). With this notice EPA is announcing the 
extension of the comment period to March 22, 2016. EPA is seeking 
public comment prior to external peer review. The document will undergo 
review during an expert peer review meeting, which will be convened, 
organized, and conducted by an independent contractor. The date and 
location of the peer review meeting will be announced in a subsequent 
Federal Register notice. All comments received in the docket by the 
closing date March 22, 2016 will be shared with the peer review panel 
for their consideration. Comments received after the close of the 
comment period may be considered by EPA when it finalizes the document. 
Members of the public may obtain the draft guidance at http://www.regulations.gov; or www.epa.gov/osa/guidelines-human-exposure-assessment or from Dr. Michael Broder via the contact information 
below.

DATES: All comments received in the docket by March 22, 2016 will be 
shared with the external peer review panel for their consideration. 
Comments received beyond that time may be considered by EPA when it 
finalizes the document.

your comment. If you send an email comment directly to EPA, without 
going through http://www.regulations.gov, your email address will be 
automatically captured and included as part of the comment that is 
placed in the public docket and made available on the Internet. If you

technical difficulties and cannot contact you for clarification, EPA 
may not be able to consider your comment. Electronic files should avoid 
the use of special characters, any form of encryption, and be free of 
any defects or viruses.

SUPPLEMENTARY INFORMATION: The current guidance document for human 
exposure assessment, Guidelines for Exposure Assessment, was published 
in 1992, reflecting the state-of-the-science in the 1970s and 1980s. 
Since its publication, the field of exposure science has undergone 
significant transformation in methods and approaches, which EPA has 
incorporated into its policies and practices to better align with the 
current state-of-the-science. The 1992 guidelines are being updated to 
reflect the updated methods and approaches.

[[Page 7792]]

    The draft guidelines benefit from over two decades of experience 
with EPA assessments conducted by Agency programs under their 
respective authorities and constraints, and from input from external 
panels, including the National Academies of Sciences and EPA's Science 
Advisory Board. This draft document builds on topics covered in the 
1992 exposure guidelines including planning and scoping for an 
assessment, data acquisition and use, modeling, and considerations of 
uncertainty in exposure assessment. It also includes new material on 
planning and conducting an observational human exposure measurement 
study and considerations of lifestages and sensitive populations in 
exposure assessments. These draft guidelines present the most current 
science used in EPA exposure assessments and incorporates information 
about the Agency's current policies.

EPA Science Advisor.
