Notice of public comment period.
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 Start Printed Page 7478only 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.

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.

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.
