          - [FRL-8957-6; Docket ID No. EPA-HQ-ORD-2009-0348]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Notice of Public Comment Period and Listening Session.

# SUMMARY:

                        EPA is announcing a public comment period and a public listening session for the external review draft document titled, “Toxicological Review of cis- and trans-1,2-Dichloroethylene: In Support of Summary Information on the Integrated Risk Information System (IRIS)” (EPA/635/R-09/006). 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 external peer-review workshop, 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. EPA intends to forward the public comments that are submitted in accordance with this notice to the external 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 October 19, 2009, 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, to develop 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 external peer review meeting. EPA welcomes the scientific and technical 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 assessment in response to the independent external peer review and the public comments. All presentations will become part of the official public record.                              ( print page 48734)    

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.

# DATES:

The public comment period begins September 24, 2009, and ends November 23, 2009. Technical comments should be in writing and must be received by EPA by November 23, 2009.

                        The listening session on the draft IRIS health assessment for cis- and trans-1,2-dichloroethylene will be held on October 19, 2009, beginning at 9:00 a.m. and ending at 4:00 p.m., Eastern Daylight Time. If you want to make a presentation at the listening session, you should register by October 12, 2009, 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.,*                         lap top 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 October 12, 2009, 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. All comments must be submitted to the docket, but comments received after the public comment period closes will not be submitted to the external peer reviewers.

# SUPPLEMENTARY INFORMATION:

## 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.
