Draft Toxicological Review of Inorganic Arsenic: In Support of 
the Summary Information on the Integrated Risk Information System 
(IRIS)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of public comment period.

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

SUMMARY: EPA is announcing a 60-day public comment period for the 2010 
draft document titled, ``Toxicological Review of Inorganic Arsenic: In 
Support of the Summary Information on the Integrated Risk Information 
System (IRIS)'' (EPA/635/R-10/001). The draft document was prepared by 
the National Center for Environmental Assessment (NCEA) within the 
EPA's Office of Research and Development (ORD). The Toxicological 
Review of Inorganic Arsenic was submitted to the EPA's Science Advisory 
Board (SAB) for external peer review in 2005. The SAB completed its 
review and submitted its final report to the EPA Administrator in June 
2007 (see EPA-SAB-07-008 at www.epa.gov/sab). EPA revised the 
Toxicological Review in response to the SAB comments. A detailed 
account of the SAB (2007) recommendations and EPA's response is 
provided in Appendix A of the 2010 draft Toxicological Review of 
Inorganic Arsenic.
    EPA has now submitted the 2010 draft Toxicological Review to the 
SAB for a focused peer review of EPA's responses to key SAB (2007) 
recommendations. EPA is also seeking a focused review by the public on 
EPA's interpretation and implementation of key SAB (2007) external peer 
review recommendations. The public comment period and SAB review are 
separate processes that provide opportunities for all interested 
parties to comment on the document. SAB's peer review meeting will be 
announced in a separate Federal Register notice. EPA intends to forward 
the public comments that are submitted in accordance with this notice 
to the SAB peer review panel prior to the meeting for their 
consideration. However, because of the timing of the SAB's peer review 
meeting, EPA can

[[Page 7478]]

only guarantee that those comments submitted by March 26, 2010, in 
response to this Federal Register notice will be provided to the SAB 
panel prior to the SAB meeting. Comments received after March 26 will 
still be provided to the SAB panel and will inform the Agency's 
revision of the draft assessment, but EPA cannot guarantee that the 
panel will have them prior to the peer review meeting. In addition, EPA 
cannot grant any requests for an extension of the comment period 
because of the scheduled SAB peer review meeting. When finalizing the 
Toxicological Review of Inorganic Arsenic, EPA intends to consider any 
public comments that EPA receives in accordance with this notice.
    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 February 19, 2010, and ends 
April 20, 2010. Comments should be in writing and must be received by 
EPA by April 20, 2010.
    EPA can only guarantee that those comments submitted by March 26, 
2010, in response to this Federal Register notice will be provided to 
the SAB panel prior to the SAB meeting. Comments received after March 
26 will still be provided to the SAB panel and will inform the Agency's 
revision of the draft assessment, but EPA cannot guarantee that the 
panel will have them prior to the peer review meeting.

Support of the Summary Information on the Integrated Risk Information 
System (IRIS)'' is available primarily via the Internet on the NCEA

SUPPLEMENTARY INFORMATION:

I. Information About IRIS

    IRIS is a human health assessment program that evaluates 
quantitative and qualitative risk information on effects that may 
result from exposure to specific 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. The IRIS database contains information for more 
than 540 chemical substances that can be used to support the first two 
steps (hazard identification and dose-response evaluation) of the risk 
assessment process. When supported by available data, IRIS provides 
oral reference doses (RfDs) and inhalation reference concentrations 
(RfCs) for chronic noncancer health effects, and oral slope factors and 
inhalation unit risks for carcinogenic effects. Combined with specific 
exposure information, government and private entities use IRIS 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.
