2012-17145. 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 [e-mail]; 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: 8601P), Office of Research and Development, U.S. Environmental Protection Agency, Washington, DC 20460; telephone: [phone], facsimile: [phone]; or email: [e-mail].

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.
