Integrated Risk Information System (IRIS); Announcement of 
Availability of Literature Searches for IRIS Assessments

AGENCY: Environmental Protection Agency.

ACTION: Notice of availability of a literature search for 
benzo(a)pyrene; request for information.

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

SUMMARY: The U.S. Environmental Protection Agency (EPA) is announcing 
the availability of a literature search for benzo(a)pyrene (CASRN 50-
32-8). EPA is also requesting scientific information on health effects 
that may result from exposure to this chemical substance. EPA's 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.

DATES: EPA will accept information related to the specific substance 
included herein as well as any other compound being assessed by the 
IRIS Program. Please submit any information in accordance with the 
instructions provided below.

ADDRESSES: Please submit relevant scientific information identified by 
docket ID number EPA-HQ-ORD-2012-0523, online at www.regulations.gov 
(EPA's preferred method); by email to Docket_ORD@epa.gov; mailed to 
Office of Environmental Information (OEI) Docket (Mail Code: 28221T), 
U.S. Environmental Protection Agency, 1200 Pennsylvania Ave. NW., 
Washington, DC 20460-0001; or by hand delivery or courier to EPA Docket 
Center, EPA West, Room 3334, 1301 Constitution Ave. NW., Washington, 
DC, between 8:30 a.m. and 4:30 p.m. Monday through Friday, excluding 
legal holidays. Information on a disk or CD-ROM should be formatted in 
Word or as an ASCII file, avoiding the use of special characters and 
any form of encryption, and may be mailed to the mailing address above.

FOR FURTHER INFORMATION CONTACT: For information on the IRIS program, 
contact Joseph DeSantis, Senior Advisor for Logistical Support, IRIS 
Division, National Center for Environmental Assessment, (mail code:

SUPPLEMENTARY INFORMATION:

Background

    EPA's 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 as well as assessments of 
potential carcinogenic effects resulting from chronic exposure. 
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.
    This data call-in is a step in the IRIS process. As literature 
searches are completed, the results will be posted on the IRIS Web site 
(http://www.epa.gov/iris). The public is invited to review the 
literature search results and submit additional information to EPA.

Request for Public Involvement in IRIS Assessments

    EPA is soliciting public involvement in assessments on the IRIS 
agenda. While EPA conducts a thorough literature search for each 
chemical substance, there may be unpublished studies or other primary 
technical sources that are not available through the open literature. 
EPA would appreciate receiving scientific information from the public 
during the information gathering stage for the assessment listed in 
this notice or any other assessments on the IRIS agenda. Interested 
persons may provide scientific analyses, studies, and other pertinent 
scientific information. While EPA is primarily soliciting information 
on new assessments, the public may submit information on any chemical 
substance at any time.
    EPA is announcing the availability of an additional literature 
search on the IRIS Web site (www.epa.gov/iris). The public is invited 
to review the literature search results and submit additional 
information to EPA. A literature search is now available for 
benzo(a)pyrene (CASRN 50-32-8) at www.epa.gov/iris under ``IRIS Agenda 
and Literature Searches.'' Additional literature searches will be 
posted as they are completed. Availability will be announced in the 
Federal Register. Instructions on how to submit information are 
provided below under General Information.
