Notice of public comment period and listening session.
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 1,2,3-, 1,2,4-, and 1,3,5-Trimethylbenzene: In Support of Summary Information on the Integrated Risk Information System (IRIS)” (EPA/635/R-11/012A). The draft assessment was prepared by the National Center for Environmental Assessment (NCEA) within the EPA Office of Research and Development (ORD). EPA is releasing this 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.
EPA's Science Advisory Board (SAB) will convene an expert panel for independent external peer review of the draft assessment. The EPA SAB is a body established under the Federal Advisory Committee Act with a broad mandate to advise the Agency on scientific matters. The public comment period and the SAB peer review are separate processes that provide opportunities for all interested parties to comment on the document. The SAB will schedule one or more public peer review meetings, which will be announced in the Federal Register at a later date.
EPA is also announcing a listening session to be held on Wednesday, August 1, 2012, during the public comment period. The purpose of the listening session is to allow all interested parties to present scientific and technical comments on the draft IRIS health assessment 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.
The public comment period begins, June 29, 2012, and ends August 28, 2012. Technical comments should be in writing and must be received by EPA by August 28, 2012.
The listening session on the draft IRIS health assessment for 1,2,3-, 1,2,4-, and 1,3,5-Trimethylbenzene (TMB) will be held on August 1, 2012, beginning at 9 a.m. and ending at 4 p.m., Eastern 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 July 25, 2012, following the detailed instructions below under SUPPLEMENTARY INFORMATION.
The draft “Toxicological Review of 1,2,3-, 1,2,4-, and 1,3,5-Trimethylbenzene: 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 http://www.epa.gov/ncea.

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, IRIS data are used by government and private entities to help characterize public health risks of chemical substances in site-specific situations and thereby support risk management decisions designed to protect public health.
II. How To Register for the Listening Session
To attend the August 1, 2012, listening session, register by July 25, 2012, by sending an email to IRISListeningSession@epa.gov (subject line: TMB Listening Session); by calling Christine Ross at 703-347-8592; or by faxing a registration request to 703-347-8689.

A copy of the agenda for the listening session will be available at the meeting.
