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 document titled, “Development of a Relative Potency Factor (RPF) Approach for Polycyclic Aromatic Hydrocarbon (PAH) Mixtures” (EPA/635/R-08/012A). 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 EPA Science Advisory Board (SAB) peer review meeting, 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. Start Printed Page 8938EPA 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. 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 April 7, 2010, 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, for developing 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 peer review meeting. EPA welcomes the 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 document in response to the independent SAB peer review and the public comments. All presentations submitted to EPA according to the instructions below 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.
The public comment period begins February 26, 2010, and ends April 27, 2010. Comments should be in writing and must be received by EPA by April 27, 2010.
The listening session on the draft document for PAH mixtures will be held on April 7, 2010, beginning at 9 a.m. and ending at 4 p.m., Eastern Standard Time. If you would like to attend the listening session, you should register by March 31, 2010. If you would like to make a presentation at the listening session, you should register by March 31, 2010, 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., laptop computer 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 March 31, 2010, 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.

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.
