I. Information About IRIS

EPA's IRIS Program is a human health assessment program that evaluates quantitative and qualitative risk information on effects that may result from exposure to 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 and decisions to protect public health. The IRIS database contains information for more than 500 chemical substances that can be used to support the first two steps (hazard identification and dose-response evaluation) of the human health risk assessment process. When supported by available data, IRIS provides health effects information and toxicity values for health effects (including cancer and effects other than cancer). Government and others combine IRIS toxicity values with exposure information to characterize public health risks of chemical substances; this information is then used to support risk management decisions designed to protect public health and the environment.

II. Extension of Comment Period

The EPA is extending the deadline for submitting comments on the draft Toxicological Review of Benzo[a]pyrene and on the draft peer review charge questions to November 21, 2013. The original deadline for comments was October 21, 2013, as announced in the Federal Register on August 21, 2013 (78 FR 51719). This decision responds to requests to extend the comment deadline from the following organizations: American Coke and Coal Chemicals Institute, American Fuel & Petrochemical Manufacturers, American Petroleum Institute, Asphalt Institute, Association of American Railroads, and the Pavement Coatings Technology Council. The EPA believes this extension will assist in providing an adequate amount of additional time for the public to review the drafts and to provide written comments. EPA released this draft assessment and peer review charge questions for the purpose of public comment. 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.

III. Bimonthly Public Meeting

In addition to the extension of the public comment period announced in this notice, the draft assessment will be discussed at the bimonthly IRIS public meeting scheduled for December 12-13, 2013. Information on this meeting, including location, time, registration, and participation procedures, will be available on the IRIS Web site (​iris/​publicmeeting/​). The purpose of the IRIS public meeting is to allow all interested parties to present scientific and technical comments on the draft IRIS health assessment and charge questions to EPA and other interested parties attending the meeting. The public comments provided in response to this notice, and at the IRIS public meeting, will be considered by the Agency prior to submitting the draft assessment to EPA's Science Advisory Board (SAB) for peer review.

IV. Peer Review

In addition to this public comment period, the draft assessment will be sent to the SAB Chemical Assessment Advisory Committee (CAAC) for peer review. 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 bimonthly public meeting announced in this notice are separate processes from the SAB/CAAC peer review. The SAB will schedule one or more public peer review meetings, which will be announced in a separate Federal Register Notice at a later date.
