ENVIRONMENTAL PROTECTION AGENCY
[FRL-9279-5; Docket ID No. EPA-HQ-ORD-2007-0664]
Integrated Risk Information System (IRIS); Announcement of
Availability of Literature Searches for IRIS Assessments
AGENCY: Environmental Protection Agency.
ACTION: Announcement of availability of literature searches for IRIS
assessments; request for information.
-----------------------------------------------------------------------
SUMMARY: The U.S. Environmental Protection Agency (EPA) is announcing
the availability of literature searches for cobalt (CASRN 7440-48-4)
and inorganic cobalt compounds, vanadium pentoxide (CASRN 1314-62-1),
vinyl acetate (CASRN 108-05-4), and Libby Amphibole asbestos. EPA is
requesting scientific information on health effects that may result
from exposure to these chemical substances. 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 substances
included herein as well as any other compounds 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-2007-0664, online at http://www.regulations.gov (EPA's preferred method); by e-mail to
ord.docket@epa.gov; mailed to Office of Environmental Information (OEI)
Docket (Mail Code: 2822T), 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 Karen Hammerstrom, IRIS Program Deputy Director, National
Center for Environmental Assessment, (mail code: 8601D), Office of
Research and Development, U.S. Environmental Protection Agency,
Washington, DC 20460; telephone: (703) 347-8642, facsimile: (703) 347-
8689; or e-mail: FRNquestions@epa.gov.

inquiries to hotline.iris@epa.gov.
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
[[Page 13403]]
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 assessments 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 additional literature
searches 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. Literature searches are now available for cobalt
(CAS No. 7440-48-4) and inorganic cobalt compounds, vanadium pentoxide
(CASRN 1314-62-1), vinyl aceate (108-05-4), and Libby Amphibole
asbestos at http://www.epa.gov/iris under ``IRIS Agenda and Literature
Searches.'' The literature search for Libby Amphibole asbestos
encompasses publicly available and peer reviewed literature that is
specific to Libby Amphibole asbestos. EPA would appreciate receiving
scientific information from the public that is specific to Libby
Amphibole asbestos, rather than general asbestos, in an effort to
support the development of an IRIS human health assessment specific for
Libby Amphibole asbestos (CASRN 1332-21-4). Instructions on how to
submit information are provided below under General Information.
