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 
    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 

DATES: The public comment period begins August 25, 2011, and ends

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
