Draft Toxicological Review of Dichloromethane: In Support of 
Summary Information on the Integrated Risk Information System (IRIS)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Public Comment Period and Listening Session.

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

SUMMARY: EPA is announcing a 60-day public comment period and a public 
listening session for the external review draft human health assessment 
titled, ``Toxicological Review of Dichloromethane: In Support of 
Summary Information on the Integrated Risk Information System (IRIS)'' 
(EPA/635/R-10/003). The draft assessment was prepared by the National 
Center for Environmental Assessment (NCEA) within EPA's Office of 
Research and Development (ORD). The public comment period and external 
peer review meeting, 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 assessment. 
EPA intends to forward the public comments that are submitted in 
accordance with this notice to the peer review panel prior to the 
meeting for their consideration. When finalizing the draft assessment, 
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 May 11, 
2010, during the public comment period for this draft assessment. This 
listening session is a step in EPA's revised IRIS process, announced on 
May 21, 2009, for developing 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 peer review meeting. 
EPA welcomes the 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 SAB peer review and the public comments. All presentations 
submitted to EPA according to the instructions below will become part 
of the official public record.
    EPA is releasing this draft assessment solely for the purpose of 
pre-dissemination peer review under applicable information quality 
guidelines. This assessment 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 March 31, 2010, and ends June 
1, 2010. Comments should be in writing and must be received by EPA by 
June 1, 2010.
    The listening session on the draft assessment for dichloromethane 
will be held on May 11, 2010, beginning at 9 a.m. and ending at 4 p.m., 
Eastern Daylight Time. If you would like to attend the listening 
session, you should register by May 4, 2010. If you would like to make 
a presentation at the listening session, you should register by May 4, 
2010, 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., laptop computer 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 May 4, 
2010, 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 
received will be submitted to the docket, but comments received after 
the public comment period closes will not be submitted to the external 
peer reviewers and will only be considered by EPA if time permits.

Support of Summary Information on the Integrated Risk Information 
System (IRIS)'' is available primarily via the Internet on the NCEA

SUPPLEMENTARY INFORMATION:

I. Information About IRIS

    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 and cancer assessments. 
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.
