Draft Toxicological Review of Vinyl Chloride and IRIS Summary for
Vinyl Chloride
AGENCY: Environmental Protection Agency.
ACTION: Notice of peer-review panel workshop and public comment period.
-----------------------------------------------------------------------
SUMMARY: The U.S. Environmental Protection Agency (EPA) is announcing
an external peer-review workshop to review the external review draft
document titled, Toxicological Review of Vinyl Chloride (NCEA-S-0619)
and the companion draft IRIS [Integrated Risk Information System]
Summary for Vinyl Chloride. The EPA is also announcing a 30-day public
comment period for the draft Toxicological Review. The peer-review
workshop will be organized, convened, and conducted by the Syracuse
Research Corporation, an EPA contractor for this external scientific
peer review. The documents were prepared by the EPA's National Center
for Environmental Assessment-Washington Office (NCEA-W) within the
Office of Research and Development. NCEA will consider the peer-review
advice and public comment submissions in revising the Toxicological
Review. While EPA is not soliciting public comments on the draft IRIS
Summary, any comments on the draft Toxicological Review received prior
to the end of the public comment period also will be considered in
revising the IRIS Summary.
DATES: The peer-review panel workshop will begin on Wednesday, June 2,
1999, at 9:00 a.m. and end at 5:30 p.m. Members of the public may
attend as observers, and there will be a limited time for comments from
the public in the afternoon. The 30-day public comment period begins
May 21, 1999, and ends June 21, 1999.
ADDRESSES: The external peer-review panel workshop will be held at the
Sheraton Crystal City Hotel, 1800 Jefferson Davis Highway, Arlington,
Virginia. The Syracuse Research Corporation, an EPA contractor, is
organizing, convening, and conducting the peer-review workshop. To
attend the workshop, register by May 27, 1999, by calling Tara Childs,

served basis. There will be a limited time for comments from the public
during the afternoon of the workshop. Please let the Syracuse Research
Corporation know if you wish to make comments.

SUPPLEMENTARY INFORMATION: The Toxicological Review of Vinyl Chloride
will provide the scientific basis for classifying the weight-of-
evidence for the carcinogenicity of vinyl chloride, deriving cancer
potency estimates for both the inhalation and oral route and deriving
an oral reference dose (RfD) and inhalation reference concentration
(RfC) for the noncancer health risk from exposure to vinyl chloride.
An earlier draft of the Toxicological Review was peer-reviewed at a
workshop in June 1997 and has been revised based on comments received.
This is the second peer-review workshop and the first public comment
period for this document.
The IRIS Summary for Vinyl Chloride is formulated from the contents
of the Toxicological Review and is included to provide interested
parties with the proposed changes to the Agency's Integrated Risk
Information System (IRIS). While EPA is not soliciting comments on the
IRIS Summary, any comments on the draft Toxicological Review received
during the public comment period also will be considered in revising
IRIS the Summary.
Dated: May 18, 1999.
