Notice of Extension of Public Comment Period on the Draft IRIS 
Carcinogenicity Assessment for Ethylene Oxide and Addition of Ethylene 
Oxide to October IRIS Bimonthly Meeting Agenda

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Extension of Public Comment Period to October 11, 
2013, and Addition of Ethylene Oxide to October IRIS Bimonthly Meeting 


SUMMARY: EPA is announcing an extension of the public comment period 
for the IRIS external review draft carcinogenicity assessment titled, 
``Evaluation of the Inhalation Carcinogenicity of Ethylene Oxide'' 
(EPA/635/R-13/128a and EPA/635/R-13/128b) and the draft peer review 
charge questions. The original Federal Register notice announcing the 
public comment period was published on July 23, 2013. We are extending 
the deadline for this public comment period from September 5, 2013, to 
October 11, 2013, at the request of the American Chemistry Council and 
the Ethylene Oxide Sterilization Association, Inc. The draft assessment 
was prepared by the National Center for Environmental Assessment (NCEA) 
within the EPA Office of Research and Development (ORD). This draft 
assessment is not final as described in EPA's information quality 
guidelines, and it does not represent and should not be construed to 
represent Agency policy or views.
    Discussion of the draft IRIS carcinogenicity assessment for 
ethylene oxide will be included on the agenda of the IRIS bimonthly 
public meeting to be held on October 23-24, 2013, at EPA offices in 
Arlington, Virginia. Information on this meeting, including meeting 
location, time, registration, and participation procedures will be

ADDRESSES: The draft ``Evaluation of the Inhalation Carcinogenicity of 
Ethylene Oxide'' is available primarily via the Internet on the NCEA 
home page under the Recent Additions and Publications menus at http://www.epa.gov/ncea. A limited number of paper copies are available from 
the Information Management Team, NCEA; telephone: 703-347-8561;

I. Information About IRIS

    EPA's IRIS Program is a human health assessment program that 
evaluates quantitative and qualitative risk information on effects that 
may result from exposure to chemical substances found in the 
environment. Through the IRIS Program, EPA provides the highest quality 
science-based human health assessments to support the Agency's 
regulatory activities and decisions to protect public health. The IRIS 
database contains information for more than 500 chemical substances 
that can be used to support the first two steps (hazard identification 
and dose-response evaluation) of the human health risk assessment 
process. When supported by available data, IRIS provides health effects 
information and toxicity values for health effects (including cancer 
and effects other than cancer). Government and others combine IRIS 
toxicity values with exposure information to characterize public health 
risks of chemical substances; this information is then used to support 
risk management decisions designed to protect public health.

II. Extension of Comment Period

    The EPA is extending the deadline for submitting comments on the 
draft ``Evaluation of the Inhalation Carcinogenicity of Ethylene 
Oxide'' and on the draft peer review charge questions to October 11, 
2013. The original deadline for comments was September 5, 2013. The 
EPA's decision responds to requests to extend the comment deadline. The 
EPA believes that this extension will assist in providing an adequate 
amount of additional time for the public to review the drafts and to 
provide written comments.

III. Bimonthly Public Meeting

    In addition to the extension to the public comment period announced 
in this notice, the draft assessment will be discussed at the first 
IRIS bimonthly public meeting scheduled for October 23-24, 2013. 
Information on this meeting, including meeting location, time, 
registration, and participation procedures will be available at the 
IRIS Web site (http://www.epa.gov/iris/publicmeeting/). The purpose of 
the IRIS public meeting is to allow all interested parties to present 
scientific and technical comments on the draft IRIS health assessment 
and charge questions to EPA and other interested parties attending the 

IV. Peer Review

    In addition to this public comment period, the draft assessment 
will be reviewed by the EPA's Science Advisory Board (SAB) Chemical 
Assessment Advisory Committee (CAAC) for peer review. The EPA SAB is a 
body established under the Federal Advisory Committee Act with a broad 
mandate to advise the Agency on scientific matters. The public comment 
period and bimonthly public meeting announced in this notice are 
separate processes from the SAB/CAAC peer review. The SAB will schedule 
one or more public peer-review meetings which will be announced in a 
separate Federal Register Notice at a later date.
