MEMORANDUM FOR VINYL CHLORIDE PANEL Re: IRIS Update
Attached is an EPA notice announcing the initiation of a Pilot Program to develop new or updated health assessments and entries in the Integrated Risk Information System (IRIS) for 11 chemicals. As previously indicated, one of these substances is vinyl chloride. The notice provides a three-step process for the submission of information on these substances, including new health effects studies and other information that would change the information currently on IRIS.
After the information is submitted, the Pilot Program calls for both internal and external peer review followed by the preparation of final health effects summaries for the IRIS data base. When it submits relevant information on vinyl chloride, the Vinyl Chloride Panel may wish to comment as to the appropriate level of external peer review needed for vinyl chloride.
The deadline for submission of information in response to the notice is May 2, 1996.

ACTION; Notice; Announcement of IRIS Pilot Program and request for technical information on Pilot chemical substances.
SUMMARY: The Integrated Risk Information System (IRIS) is a data base of the United States Environmental Protecticm Agency (EPA) that contains EPA scientific consensus positions on potential human health effects from environmental contaminants. On February 25,1993 (58 FR 11490) EPA requested public comment to improve
SUPPLEMENTARY INFORMATION:
Background
The Integrated Risk Information System (IRIS) is an EPA data base containing Agency consensus scientific positions on potential adverse human health effects that may result horn chronic (or lifetime) exposure to environmental contaminants. IRIS currently provides heelth effects information on over 500 specific chemical substances.
IRIS contains chemical-specific

the issues concern the way consensus evaluation. IRIS information includes
the reference doee for aon-cancsr health effects resulting from oral exposure, ihe
refseiiccoQCCDtnttcfcvnoncencer health effects rosuMngfrom Inhalation exposure, and the carcinogen . assessment for both oral and inhalation
exposure. Combined with specific situational exposure assessment information, the summary health hazard
information in DUS may be used as a source in evaluating potential public health risks from environmental
contaminants. As the data base has expanded and its
use has increased over the last decade, issues have surfaced with regard to entering new information in a timely
manner, while soliciting information from a brand spectrum of outside scientists mid the public. In 1993, an EPA tmw evaluated the status of DUS and proposed options for improvement This effort was announced in a Notice in the Federal Register of February 25, 1993 (58 FR 11490). The Notice addressed the use of DUS, and avenues for public involvement and external scientific peer review of DUS summaries and supporting documents. Public involvement means opportunities for
affected or interested parties to have some level of input into DUS health hazard information, such as providing relevant health data. Public involvement can involve a broader spectrum of participants than external peer review, which refers to a critical scientific appraisal by experts outside of EPA.
The Agency and the public have continued to express support for maintaining IRIS and strengthening the process far developing consensus health information, public involvement, and peer review. This support has given rise to the new Pilot Program.

The Pilot Prograaa
As a consequence of analyzing the DUS program and considering suggestions received about DUS over the past several yean, the Agency has decided to test some improvements through a Pilot Program. The Pilot will primarily address the scientific consensus and review process that precedes DUS data base entries. EPA will develop (or update, for existing entries) all non-cancer and cancer information for the eleven Pilot substances. The PUot process will Consist ot (1) A call for technical information on the eleven substances from the public via this FR Notice.

The appropriate level of external peer review will be determined for each chemical substance. Depending upon the complexity of the scientific information and other factors, die form of the peer review will either be vie mail, forums of experts, or formal federal advisory committees.
The Pilot will also teat some improvements in IRIS entries to more fully characterize health information associated with each chemical. For example, the IRIS summaries will provide greeter elaboration of. uncertainties in the data, and our confidence in the assessment
Pilot Substances
The eleven Pilot chemical substances were chosen on the basis of the Agency's need for new or updated hazard or dose-response information, and in an effort to represent a range of technical complexity so the new process is realistically tested. Qualitative and quantitative information will be developed for non-cencer and cancer effects of all Pilot substances, hi some cases, the assessment will be developed for the first time; in others, the assessment will be reviewed in light of new information and updated in IRIS if appropriate.
The following substances will be reviewed under the Pilot Program:
NimCAS.No,
Arsenic--7440-38-2 Bentazon--25057-89-0 Beryllium--7440 41-7 Chlordane--57-74-9 Chromium (IQ)--16065-85-1

Submittal of Information
The Pilot Program is designed to provide early opportunity for public involvement. While the Agency conducts a thorough literature search for each chemical substance, there mav be other articles or unpublished studies we are not aware of. The Agency would greatly appreciate receiving scientific
Information bom tha public during the
informationgathering stage of the Pilot
Interested persons should provide
scientific comments, analyses, studies,
and other pertinent scientific
information. The moat useful
documents for EPA are unpublished
studies or other primary technical
sources that we may not otherwise
obtain through open literature searches.
Also note that if you have submitted
certain information previously, such as
in response to the 1993 FR Notice, then
there is no need to resubmit that
information. Information bom the
public is being solicited for 30 days via
this Notice.
As described in the 1993 FR Notice,
submissions will be handled in a three-
step process;
1. First, interested parties should
simply provide a list (submisscm
inventory], briefly identifying all the
information they wish to submit to the
IRIS Information Submission Desk. The
list should specify by name and CAS
(Chemical Abstract Reghtey) number the
Pilot chemical substatG^Se which the
information pertains,
the
assessment that is being addressed (e.g.,
carcinogenicity), and describe briefly
the information being submitted for
consideration. When possible,
documents should be listed in scientific
citation format, that is, authors), title,
journal, and date. A cover letter should
state that the correspondence is an IRIS
Submission, describe in general terms
the purpose of the submission, and
include names, addresses, and
telephone numbers of persons to contact
for additional information on the
submission.
2. In the second step. EPA will
compare the submission inventory to
existing files and identify the
information that should be submitted.
This step will help prevent an influx of
duplicative information. The submitter
will receive notification requesting full
submission of the selected material.
3. In the third step, the submitter
should promptly send in the
information requested by EPA.
Submittals should include a cover letter
addressing all of the points in item 1
above. In addition, persons submitting
results of new health effects studies
should include a specific explanation of
how and why the study results could
change the information in IRIS.
Submitters sending paper copies are
requested to send three copies, at least
one of which should be unbound. As
mentioned previously (see ADOAESSES),
the Agency also welcomes electronic
submittal of information in response to
Jus Notice. EPA will transfer all
correspondence received electronically
intoprinted, paperfonn as it is j and wlUpfoce^Tpqw cop*
with all Information submitted in writingto the IRIS Submission j Receipt ofinformation will be acknowledged in the manner in which it is received, that is. in writing or electronically.
Other aspects of the information submittal process are unchanged and are detailed in the 1993 FR Notice. Most importantly. Confidential Business Information (CBI) should not be submitted to the IRK Submission Desk. CBI must be submitted to the appropriate office via approved Agamy procedures for submission of CBI sscodified in the Code of Federal Regulations (40 CFR, Part 2, Subpart B). If a submitter believes that a CBI submission rrmtaine information with implications far IRIS, it should be noted in the cover letter accompanying the submission to the appropriate office;'
