Draft Toxicological Review of Hydrogen Cyanide and Cyanide Salts: 
In Support of the Summary Information in 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 public comment period and a public 
listening session for the external review draft document titled, 
``Toxicological Review of Hydrogen Cyanide and Cyanide Salts: In 
Support of Summary Information on the Integrated Risk Information 
System (IRIS)'' (EPA/635/R-08/016). The draft document was prepared by 
the National Center for Environmental Assessment (NCEA) within the 
EPA's Office of Research and Development (ORD). The public comment 
period and the external peer-review workshop, 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 intends to forward the public comments 
that are submitted in accordance with this notice to the external peer-
review panel prior to the meeting for their consideration. When 
finalizing the draft document, EPA intends to consider any public 
comments that EPA receives in accordance with this notice.
    EPA is also announcing a listening session to be held on October 
27, 2009, during the public comment period for this draft document. 
This listening session is a step in EPA's revised IRIS process, 
announced on May 21, 2009, to develop human health assessments for 
inclusion in the IRIS database. 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 during the public comment period and before the external peer 
review meeting. 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 in response to the independent external peer review and the 
public comments. All presentations will become part of the official 
public record.
    EPA is releasing this draft document solely for the purpose of pre-
dissemination peer review under applicable information quality 
guidelines. This document has not been formally disseminated by EPA. It 
does not represent and should not be construed to represent any Agency 
policy or determination.

DATES: The public comment period begins September 23, 2009, and ends 
November 23, 2009. Technical comments should be in writing and must be 
received by EPA by November 23, 2009.
    The listening session on the draft IRIS health assessment for 
Hydrogen Cyanide and Cyanide Salts will be held on October 27, 2009, 
beginning at 9 a.m. and ending at 4 p.m., Eastern Daylight Time. If you 
want to make a presentation at the listening session, you should 
register by October 20, 2009, indicate that you wish to make oral 
comments at the session, and indicate the length of your presentation. 
When you register, please indicate if you will need audio-visual aid 
(e.g., lap top and slide projector). In general, each 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 October 20, 2009, the listening session will be cancelled 
and EPA will notify those registered of the cancellation.
    Listening session participants who want EPA to share their comments 
with the external peer reviewers 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. Comments submitted to the docket prior to the end of the public 
comment period will be submitted to the external peer reviewers and 
considered by EPA in the disposition of public comments. All comments 
must be submitted to the docket, but comments received after the public 
comment period closes will not be submitted to the external peer 
reviewers.

ADDRESSES: The draft ``Toxicological Review of Hydrogen Cyanide and 
Cyanide Salts: In Support of Summary Information on the Integrated Risk 
Information System (IRIS)'' is available primarily via the Internet on 
the NCEA home page under the Recent Additions and Publications menus at

SUPPLEMENTARY INFORMATION: 

I. Information About IRIS

    IRIS is a database that contains potential adverse human health 
effects information that may result from chronic (or lifetime) exposure 
to specific chemical substances found in the environment. The database 
(available on the Internet at http://www.epa.gov/iris) contains 
qualitative and quantitative health effects information for more than 
540 chemical substances that may be used to support the first two steps 
(hazard identification and dose-response evaluation) of a risk 
assessment process. When supported by available data, the database 
provides oral reference doses (RfDs) and inhalation reference 
concentrations (RfCs) for chronic health effects, and oral slope 
factors and inhalation unit risks for carcinogenic effects. Combined 
with specific exposure information, government and private entities can 
use IRIS data to help characterize public health risks of chemical 
substances in a site-specific situation and thereby support risk 
management decisions designed to protect public health.
