Draft Toxicological Review of Libby Amphibole Asbestos: In 
Support of the Summary Information on the Integrated Risk Information 
System (IRIS)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of public comment period and listening session.

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

SUMMARY: EPA is announcing a 60-day public comment period and a public 
listening session for the external review draft human health assessment 
titled ``Toxicological Review of Libby Amphibole Asbestos: In Support 
of Summary Information on the Integrated Risk Information System 
(IRIS)'' (EPA/635/R-11/002A). The draft assessment was prepared by 
staff in both EPA's Region 8 Office (Colorado, Montana, North Dakota, 
South Dakota, Utah, Wyoming, and 27 tribal nations), and the National 
Center for Environmental Assessment (NCEA) within the EPA Office of 
Research and Development (ORD). EPA is releasing the draft assessment 
for the purposes of public comment and peer review. 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. When finalizing the draft document, 
EPA intends to consider any public comments that EPA receives in 
accordance with this notice. The public comments submitted in 
accordance with this notice will be made available to the peer review 
panel.
    The draft document is also being provided to EPA's Science Advisory 
Board (SAB), a body established under the Federal Advisory Committee 
Act, for independent external peer review. The public comment period 
and the EPA Science Advisory Board (SAB) peer-review, which will be 
scheduled at a later date and announced in the Federal Register, are 
separate processes that provide opportunities for all interested 
parties to comment on the document.
    EPA is also announcing a listening session to be held on October 6, 
2011 during the public comment period for this draft assessment. The 
purpose of the listening session is to allow all interested parties to 
present scientific and technical comments on draft IRIS health 
assessments to EPA and other interested parties attending the listening 
session. EPA welcomes the scientific and technical comments that will 
be provided to the Agency by the listening session participants. The 
comments will be considered by the Agency as it revises the draft 
assessment after the independent external peer review. If listening 
session participants would like EPA to share their comments with the 
external peer reviewers, they should also submit written comments 
during the public comment period using the detailed and established 
procedures described in the SUPPLEMENTARY INFORMATION section of this 
notice.

DATES: The public comment period begins August 25, 2011, and ends 
October 24, 2011. Technical comments should be in writing and must be 
received by EPA by October 24, 2011.
    The listening session on the draft IRIS health assessment for Libby 
Amphibole Asbestos will be held in Arlington, VA, on October 6, 2011, 
beginning at 1 p.m. and ending at 5 p.m., Eastern Daylight Time, or 
when the last presentation has been completed. If you would like to 
make a presentation at the listening session, you should register by 
September 29, 2011. To attend the listening session, register by

presentation should be no more than 30 minutes. If, however, there are 
more requests for presentations than the allotted time allows, then the 
time limit for each presentation will be adjusted. A copy of the agenda 
for the listening session will be available at the meeting. If no 
speakers have registered by September 29, 2011, the listening session 
will be cancelled and EPA will notify those registered of the 
cancellation.
    Listening session participants who would like EPA to share their 
comments with the external peer reviewers should also submit written 
comments to the docket during the public comment period using the 
detailed and established procedures described in the SUPPLEMENTARY 
INFORMATION section of this notice. Comments submitted to the docket

SUPPLEMENTARY INFORMATION: 

I. Information About IRIS

    EPA's Integrated Risk Information System (IRIS) provides 
information about over 540 chemicals to which the public may be exposed 
from releases to air, water, and land and through the use and disposal 
of chemicals. IRIS assessments provide a scientific foundation for 
decisions to protect public health across EPA's programs and regions 
under an array of environmental laws. The IRIS database is publicly 
available online at http://www.epa.gov/iris and is used by state and 
local governments, environmental specialists, healthcare professionals, 
and international institutions to characterize the potential health 
effects of contaminant exposure. Over the past 2 years, EPA has 
strengthened and streamlined the IRIS program, improving transparency 
and increasing the number of final assessments added to the database. 
Continually improving the IRIS program is an ongoing priority for the 
Agency.

II. How To Submit Technical Comments to the Docket at http://www.regulations.gov

[[Page 53127]]

time permits. It is EPA's policy to include all comments it receives in 
the public docket without change and to make the comments available 
online at http://www.regulations.gov, including any personal 
information provided, unless a comment includes information claimed to 
be Confidential Business Information (CBI) or other information whose 
disclosure is restricted by statute. Do not submit information that you 
consider to be CBI or otherwise protected through http://www.regulations.gov or e-mail. The http://www.regulations.gov Web site

your comment. If you send an e-mail comment directly to EPA without 
going through http://www.regulations.gov, your e-mail 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 
submit an electronic comment, EPA recommends that you include your name 
and other contact information in the body of your comment and with any 
disk or CD-ROM you submit. If EPA cannot read your comment due to 
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. For additional information about EPA's public 
docket visit the EPA Docket Center homepage at http://www.epa.gov/epahome/dockets.htm.
    Docket: All documents in the docket are listed in the http://www.regulations.gov index. Although listed in the index, some 
information is not publicly available, e.g., CBI or other information 
whose disclosure is restricted by statute. Certain other material, such 
as copyrighted material, will be publicly available only in hard copy. 
Publicly available docket materials are available either electronically 
in http://www.regulations.gov or in hard copy at the OEI Docket in the 
EPA Headquarters Docket Center.
