OPINION
AND
ORDER OF THE
BOARD
(by C.
A.
Manning):
On September
3,
1992, the Board added to its rules
a list of
263 toxic air contaminants which may pose a significant risk to
human health,
as mandated by Section 9.5(c)
of the Environmental
Protection Act
(Act).
(415 ILCS 5/9.5(c)
(1992))(In Re:
Air
Toxic Contaminants List (September
3,
1992) R90-1(A)
135 PCB
583).
The Air Toxics rulemaking was initiated by a proposal
filed by the Illinois Environmental Protection Agency (Agency) on
January
2,
1990.1
Due to the nature of some of the questions
arising during the public hearing and comment periods in docket
R90-l(A)
Toxic Air Contaminants List,
the Board deferred action
on some issues, to Dockets R90-l(B),
(C),
and
(D).
Today the
Board is addressing only Docket R90-1(D),
In Re:
Toxic Air
Contaminants List, Styrene.
On June
4,
1992, the Board authorized submittal of a revised
set of rules to the Joint Committee on Administrative Rules
(JCAR)
for second notice review.
These rules were considered by
JCAR at its July 14 and August
11,
1992, meetings.
JCAR issued
an objection to the listing of one chemical, styrene.
(16 Ill.
Reg.
13372, August 28,
1992.)
In response to the objection, by
separate action in RES 92-1, the Board deleted styrene from the
list,
and opened R90-1, Docket D in order to further consider
styrene.
This
is discussed in detail
in the Board’s resolution
and order In Re:
Toxic Air Contaminants List (September
3,
1991)
RES 92—1,
R90—1(A)
and R90—1(D),
135 PCB 625.
On October
1,
1992,
the Board
issued an order requesting
public comments
in this matter.
The Board received three

(15
Ill. Reg. 14969).
The Board proposed these rules for second notice
in its opinion and order of June
4,
1992.

the Board adopted a final notice opinion and order in this matter.
(16 Ill.

comments
(PC.
#68,
69,
and 70)2 in response to this request.
On
November
19,
1992,
the Board issued an order establishing a two
week period in which interested parties could respond to the
comments.
On December
3,
1992,
the Board extended the response
period by two weeks until December 30,
1992.
The Board received
one response.
Discussion
The Board today has two options.
It may either proceed with
the listing of styrene by initiating a first notice publication
of the proposed rule in the Illinois Register or not proceed with
the listing of styrene and dismiss this docket.
In order to
determine the appropriate course of action in this matter, the
Board must consider two issues:
1.
Are the data on the mutagenicity of styrene submitted by
the Styrene Information and Research Center
(SIRC)
persuasive enough to override the determination by the
International Agency for Research on Cancer
(IARC)
that
styrene should be considered a potential human health
threat?
2.
If SIRC’s data are accepted, are the effects produced by
styrene, as documented in the exhibits
in the record, such
that the statutory definition of a Toxic Air Contaminant
(TAC)
does not apply?3
The Board will consider these issues in light of the information
contained in the docket
(A)
record and the public comments and
responses received on the issue of styrene.
On July 14,
1992,
SIRC filed comments to JCAR that assert
that:
SIRC’s numerous submissions to the Board
include a review by SIRC of all the animal,
human,
inutagenic, and genotoxic studies
2The
public
comments
were
numbered
consecutively
with
following
those filed
in the other subdockets.
3The statutory definition of TAC
is found at Section 9.5(c)
of the Act.
Section 9.5(c)
states, that the toxic air
contaminant list published under this subsection shall include,
“any air contaminant which may cause or significantly contribute
to an increase in mortality or an increase in serious
irreversible or incapacitating reversible illness,
or may pose a
significant threat to human health or the environment.”
(See
Also,
35 Ill.
Adm. Code 232.200)
3
relied on by
IARC.
In addition SIRC
submitted reviews of the animal,
human,
and
mutagenic/genotoxic literature for styrene
prepared by leading experts.
These
submissions, which we believe were never
considered by the Board or IEPA,
demonstrate
that styrene does not merit classification as
a carcinogen and does not, therefore,
meet
the statutory definition of a TAC.
(7/14/92
Comments of SIRC before JCAR at 4.)
However,
in PC.
#68 the Agency urges the Board to proceed
with the listing of styrene.
The Agency asserts that styrene is
a 2B carcinogen and should be listed.
The Agency’s comments
explain that its determination is based at least in part on
IARC’s determination that styrene is carcinogenic.
The Agency
also states in PC.
#68 that it does not feel that SIRC has
rebutted IARC’s determination.
The Agency in PC.
#68 contends that:
SIRC has submitted information concerning
styrene which the Agency believes represents
a biased opinion of SIRC scientists.
SIRC
re-reviewed the same studies utilized by IARC
when IARC concluded that styrene is
carcinogenic.
The resulting analysis
presented by SIRC does not rebut the decision
by
IARC.
The Agency has examined SIRC’s
submissions and has found nothing to clearly
refute the IARC conclusion.
SIRC has
presented nothing new.
Based on this, the
Agency maintains that,
since styrene falls
within the accepted listing criteria, styrene
should be listed.
(PC. #68 at 4.)
The Agency also states that,
“the Agency
is not in a position to
dispute the judgement of an internationally recognized carcinogen
listing source such as IARC”
(PC.
#68 at
4)
and notes that,
“styrene is listed as a Hazardous Air Pollutant in the Clean Air
Act at 42 U.S.C.
§7412.”
(Id.),
a fact also acknowledged by SIRC
(7/14/92 SIRC before JCAR at 1).
In its most recent comment
(PC. #69)
SIRC states that it
believes that it has submitted sufficient evidence to demonstrate
that styrene
is not a carcinogen.
It is SIRC’s position that the
genotoxicity data about styrene does not provide a clear basis to
conclude that styrene should be classified as a carcinogen.
SIRC
also comments that its purpose is to reiterate its position which
it feels has been made clear
in its previous comments.
Specifically,
SIRC refers to SIRC exhibit #1 attachments A—G,
SIRC exhibits
#2-5,
PC. #29 and PC.
#54.
The Board notes that in
4
addition to SIRC’s testimony and exhibits submitted at the
Board’s September
6,
and 7,
1990,
hearings, the Board has on file
prefiled testimony from the following dates:
August
24,
1990,
March 11,
1991,
and December 24,
1991,
submitted by SIRC.
Additionally, the Board notes that on December 31,
1991,
SIRC
submitted questions to the Board directed to the Agency.
The following is a list of SIRC exhibit #1 attachments A-G
submitted as prefiled testimony in support of SIRC’s position
that styrene should not be listed:

The Board has examined the data provided by SIRC and has not
found it to be persuasive.
Three of the five referenced
publications sponsored by SIRC lack external verification or peer
5
review.
Of the remaining two, there is no indication when and
where one was published and the other is
a draft document of the
USEPA’s Science Advisory Board Drinking Water Committee.
There
is also no indication that any of these latter documents have
been subject to verification or an external peer review.
Although this “grey literature” arguably contains valid
scientific conclusions, the Board asserts that it has not been
subject to a rigorous enough review to overturn the conclusions
of an international agency that specializes in reviewing studies
on carcinogenicity,
mutagenicity, and genotoxicity.
The Board
also notes that although SIRC states that these reports were
prepared by “leading experts”, there
is little in the record to
apprise the Board of these experts’ qualifications.
In addition to the comments discussed above,
the Board
received two other filings regarding styrene.
Both filings
support the Board’s conclusion that styrene should be listed.
The first comment received was a collective comment from the
Sierra Club along with the Coalition for Consumer Rights and the
Chicago Lung Association (Sierra Club et al.)
(PC. #70).
Sierra
Club et al. commented that it is their belief that the literature
demonstrates the serious chronic toxicity effects of styrene
exposure.
Thus, they argue, regardless of styrene’s
carcinogenicity effects,
it should be listed because of its
chronic toxicity.
(PC. #70 at 3.)
On December
18,
1992,
the Agency filed a response to the
comments of Sierra Club et al..4
In the response, the Agency
states that it “maintains its position that styrene be listed
based on the classification of the International Agency for
Research on Cancer”.
(jçj. at 1.)
The Agency also states that it
has not performed an independent analysis of the toxicity of
styrene because there is sufficient evidence supporting the
listing of styrene as a carcinogen.
(Id at 2.)
CONCLUSION
The Board has reviewed the data and testimony in the record,
the public comments,
and the responses to the public comments.
Based on its review,
the Board today proposes for first notice
publication an order that would add the chemical styrene to the
list of toxic air contaminants at 35
Ill.
Adm. Code 232.Appendix
A.
The Board notes that once this notice
is published in the
Illinois Register,
interested parties will have forty-five days
to file comments on the proposed amendment.
The Board does not
intend to conduct another hearing in this matter unless a hearing
is requested pursuant to Section 5—40
of the Illinois
4No public comment number was given to this document.
