The National Toxicology Program (NTP) Center for the Evaluation 
of Risks to Human Reproduction (CERHR): Availability of Draft Expert 
Panel Reports on Ethylene Glycol and Propylene Glycol, Request for 
Public Comment, and Expert Panel Meeting Planned


    Summary: The NTP CERHR announces:
    1. The availability of the draft expert panel reports on ethylene 
glycol and propylene glycol and solicits written public comments on the 
reports January 23, 2003.
    2. An expert panel meeting on February 11-13, 2003, at the Holiday 
Inn Old Town Select, Alexandria, Virginia and invites the public to 
present oral comments at this meeting.
    Questions about the draft expert panel reports, submission of 
public comments, and the expert panel meeting should be directed to Dr. 
Michael Shelby, CERHR director (contact information below).


Draft Expert Panel Reports on Ethylene Glycol and Propylene Glycol 
Available


    The CERHR announces the availability of draft expert panel reports 
on ethylene glycol (CASRN 107-21-1) and propylene glycol (CASRN 57-55-
6). Most ethylene glycol is used as a chemical intermediate in the 
production of polyester compounds. There is widespread public exposure 
to ethylene glycol due to its use as automotive antifreeze and as a de-
icer for aircraft. The toxicology database on ethylene glycol includes 
recent mechanistic data and occupational exposure information. 
Propylene glycol, similar in structure to ethylene glycol, is used as 
an antifreeze and de-icing solution and in various paints and coatings. 
Propylene glycol is approved for use in foods, drugs, and cosmetics.
    Each draft expert panel report has the following sections:


1.0 Chemistry, Use, and Human Exposure
2.0 General Toxicological and Biological Effects
3.0 Developmental Toxicity Data
4.0 Reproductive Toxicity Data
5.0 Summary, Conclusions, and Critical Data Needs (to be written at 
expert panel meeting)


    Sections 1-4 will be available to the public by December 4, 2003, 
and can be obtained electronically on the CERHR web site (http://cerhr.niehs.nih.gov
) or in hard copy by contacting Dr. Michael Shelby, 
Director CERHR (NIEHS, 79

Request for Written Comments on Draft Expert Panel Reports


    The CERHR invites written public comments on sections 1-4 of the 
draft expert panel reports on ethylene glycol and propylene glycol. 
Comments can be submitted in hard copy or electronic format and must be 
received by the CERHR by January 23, 2003. These comments will be 
distributed to the expert panel and CERHR staff for consideration in 
revising the draft reports and in preparing for the expert panel 
meeting. They will be posted on the CERHR website prior to the expert 
panel meeting. These comments should be sent to Dr. Michael Shelby at 
the address provided above. Persons submitting written comments are 
asked to include their name and contact information (affiliation, 
mailing address, telephone and facsimile numbers, e-mail, and 
sponsoring organization, if any).


Expert Panel Meeting Planned


    The CERHR will hold an expert panel meeting February 11-13, 2002, 
at the Holiday Inn Old Town Select, 480 King Street, Alexandria, VA 
22314 (telephone: 703-549-6080, facsimile: 684-6508). The CERHR will 
ask the expert panel to review the scientific evidence regarding the 
potential reproductive and/or developmental toxicity associated with 
exposure to ethylene glycol and to propylene glycol. The expert panel 
will review and revise the draft expert panel reports and reach 
conclusions regarding whether exposure to ethylene glycol or propylene 
glycol is a hazard to human development or reproduction. The expert 
panel will also identify data gaps and research needs.
    This meeting is open to the public and attendance is limited only 
by the available meeting room space. The meeting will begin at 8:30 
a.m. each day. On February 11 and 12 it is anticipated that a lunch 
break will occur from noon-1 p.m. and that the meeting will adjourn 5-6 
p.m. The meeting is expected to adjourn by noon on February 13; 
however, adjournment may occur earlier or later depending upon the time 
needed by the expert panel to complete its work. Anticipated agenda 
topics for each day are listed below. Following the expert panel 
meeting and completion of the expert panel reports, the CERHR will post 
the reports on its website and solicit public comment through a Federal 
Register notice.

Background Information About the CERHR


    The NTP established the NTP CERHR in June 1998 (63 FR 68782, 
December 14, 1998). The CERHR is a publicly accessible resource for 
information about adverse reproductive and/or developmental health 
effects associated with exposure to environmental and/or occupational 
exposures. Expert panels conduct scientific evaluations of agents 
selected by the CERHR in public forums.
    The CERHR invites the nomination of agents for review or scientists 
for its expert registry. Information about CERHR and the nomination 
process can be obtained from its homepage (http://cerhr.niehs.nih.gov) 
or by contacting Dr. Shelby (contact information provided above). The 
CERHR selects chemicals for evaluation based upon several factors 
including production volume, extent of human exposure, public concern, 
and published evidence of reproductive or developmental toxicity.
    CERHR follows a formal, multi-step process for review and 
evaluation of selected chemicals. The formal evaluation process was 
published in the Federal Register notice July 16, 2001 (66 FR 37047-48) 
and is available on the CERHR website under ``About CERHR'' or in 
printed copy from the CERHR.
