Risk Information System (IRIS) 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of listening session. 

SUMMARY: EPA is announcing a listening 

session to be held on October 7, 2009, 

during the public comment period for 

the external review draft document 

entitled, ‘‘Toxicological Review of Ethyl 

Tertiary Butyl Ether: In Support of 

Summary Information on the Integrated 

Risk Information System (IRIS)’’ (EPA/ 

635/R–08/019A). 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 public comments. All 

presentations will become part of the 

official public record. 

The EPA’s draft assessment and peer 

review charge are available via the 

Internet on the National Center for 

Environmental Assessment’s (NCEA) 

home page under the Recent Additions 

and Publications menus at http:// 

www.epa.gov/ncea. 

DATES: The listening session on the draft 

IRIS health assessment for Ethyl 

Tertiary Butyl Ether will be held on 

October 7, 2009, beginning at 9 a.m. and 

ending at 4 p.m., Eastern Daylight Time. 

If you want to make a presentation at 

the listening session, you should 

register by September 30, 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 audiovisual 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 September 

30, 2009, the listening session will be 

cancelled and EPA will notify those 

registered of the cancellation. 

The public comment period for 

review of this draft assessment was 

announced previously in the Federal 

Register (FR) (74 FR 42069) on August 

20, 2009. As stated in that FR notice, the 

public comment period began on 

August 20, 2009, and ends October 19, 

2009. Any technical comments 

submitted during the public comment 

period should be in writing and must be 

received by EPA by October 19, 2009, 

according to the procedures outlined 

below. Only those public comments 

submitted using the procedures 

identified in the August 20, 2009 FR 

notice by the October 19, 2009 deadline 

will be provided to the independent 

peer-review panel prior to the peerreview meeting. The date and logistics 

for the peer-review meeting will be 

announced later in a separate FR notice. 

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

be submitted to the external peer 

reviewers.

SUPPLEMENTARY INFORMATION: 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. 

This listening session is a step in 

EPA’s revised process, announced on 

May 21, 2009, for development of 

human health assessments for inclusion 

on IRIS. The updated process is posted 

on the IRIS home page at http:// 

www.epa.gov/iris.
