Response

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of EPA's response to a 
petition it received under section 21 of the Toxic Substances Control 
Act (TSCA). The petition was received from an individual on November 
19, 2009. The petitioner requested EPA to ``establish regulations 
prohibiting the use and distribution in commerce of Hevea brasiliensis 
baled natural-rubber for the manufacture of tires, wherein said rubber 
fails to satisfy The American Society for Testing Materials method ASTM 
D1076-06 (Category 5).'' The petition states: ``Implementation of an 
EPA regulation that guides tire

[[Page 7587]]

manufacturers to use Hevea brasiliensis baled natural-rubber that 
satisfies ASTM D1076-06 (Category 5) may affect the incidence of Hevea 
brasiliensis natural-rubber allergies and allergy induced autism.'' 
After careful consideration, EPA has denied the TSCA section 21 
petition for the reasons discussed in this notice.

II. Background

A. What Action was Requested Under this TSCA Section 21 Petition?

    On November 19, 2009, an individual filed a petition with EPA to 
``establish regulations prohibiting the use and distribution in 
commerce of Hevea brasiliensis baled natural-rubber for the manufacture 
of tires, wherein said rubber fails to satisfy The American Society for 
Testing Materials method ASTM D1076-06 (Category 5),'' because 
``Implementation of an EPA regulation that guides tire manufacturers to 
use Hevea brasiliensis baled natural-rubber that satisfies ASTM D1076-
06 (Category 5) may affect the incidence of Hevea brasiliensis natural-
rubber allergies and allergy induced autism'' (Refs. 1 and 2).
    This petition is similar to a previous petition that the same 
individual filed with EPA in March 2008 requesting that EPA ``establish 
regulations prohibiting the use and distribution in commerce of Hevea 
brasiliensis [italics added] natural rubber latex adhesives having a 
total protein content greater than 200 micrograms per [gram] dry weight 
of latex based on the American Society for Testing and Materials method 
ASTM D1076-06 (Category 4).'' EPA denied the petition in June 2008 
(Ref. 3).

B. What Support Does the Petitioner Offer for this Request?

    1. Exhibit A is a Portable Document Format (PDF) of a webpage from 
the website of the Journal of Allergy and Clinical Immunology (http://
www.jacionline.org/article/S0091-6749(95)70156-7/abstract), dated 
November 13, 2009, providing an abstract of an article entitled ``Latex 
Allergen in Respirable Particulate Air Pollution'' (Ref. 1). Exhibit A 
is offered to support the petition's statements that ``tires contain 
... Hevea brasiliensis baled natural-rubber,'' ``Hev-b 
proteins1 are extractable from tire natural-rubber dust,'' 
``urban air samples have been shown to contain irregular inhalable-
black particulates from airborne tire natural-rubber dust,'' and ``the 
impact of the particles should be considered in the issue of morbidity 
and mortality rates associated with respiratory diseases and air 
pollution.'' For purposes of reviewing the petition, EPA obtained a 
full copy of the article (Ref. 8).
---------------------------------------------------------------------------

    \1\ The petition refers to antigenic proteins from Hevea 
brasiliensis as ``Hev-b proteins.''
---------------------------------------------------------------------------

    2. Exhibit B is a PDF of a webpage from the website of NOVA Science 
Publishers, Inc., (http://www.novapublishers.com/catalog/advanced_
search_result.php?keywords=allergies+and+autism&x=13+y=9) dated 
November 13, 2009, which advertises, and includes an abstract of, a 
publication written by the petitioner entitled ``Allergies and Autism'' 
(Ref. 1, Exhibit B) is offered to support the petitioner's statements 
that ``Hev-b proteins affect the incidence of hyper-adaptive immunity 
and atypical neurological development in allergy sensitive children,'' 
and ``repeated exposure to the Hev-b proteins from Hevea brasiliensis 
baled natural-rubber has been shown to cause an increased incidence of 
allergies.'' According to NOVA Science Publishers, Inc., ``Allergies 
and Autism'' is scheduled to be published in the first quarter of 2010. 
At EPA's request, the petitioner provided EPA with a copy of his 
publication, which ``explores how certain proteins induce hyper 
adaptive-immunity affecting Autism Spectrum Disorders'' (Ref. 4).
    3. Exhibit C is a PDF of a photograph labeled ``VYTEX-BALE.'' 
Exhibit C is offered to support the petitioner's statement that ``ultra 
low-protein Hevea

[[Page 7588]]

brasiliensis baled natural-rubber is available commercially'' (Ref. 1).

C. What are the Legal Standards Regarding TSCA Section 21 Petitions and 
TSCA Section 6 Rules?

    Section 21(b)(1) of TSCA requires that the petition ``set forth the 
facts which it is claimed establish that it is necessary'' to issue the 
rule or order requested. 15 U.S.C. 2620(b)(1). Thus, TSCA section 21 
implicitly incorporates the statutory standards that are required to 
issue the requested rule or order. In addition, TSCA section 21 
establishes standards that a court must use to decide whether to order 
EPA to initiate rulemaking in the event of a lawsuit after denial of a 
TSCA section 21 petition. 15 U.S.C. 2620(b)(4)(B).
    The petition asks EPA to ``establish regulations prohibiting the 
use and distribution in commerce of Hevea brasiliensis baled natural-
rubber for the manufacture of tires, wherein said rubber fails to 
satisfy The American Society for Testing Materials method ASTM D1076-06 
(Category 5),'' but does not state under which provision of TSCA the 
regulation should be issued. Only TSCA section 6, however, appears to 
be applicable, because it authorizes the promulgation of regulations on 
chemical substances and mixtures to the extent necessary to protect 
adequately against unreasonable risk, including prohibiting the 
manufacture or distribution in commerce of a chemical substance for a 
particular use. Accordingly, EPA has relied on the standards in TSCA 
section 21 and section 6 to evaluate this petition.
    In order to promulgate a rule under TSCA section 6, the EPA 
Administrator must find that ``there is a reasonable basis to conclude 
that the manufacture, processing, distribution in commerce, use, or 
disposal of a chemical substance or mixture . . . presents or will 
present an unreasonable risk of injury to health or the environment.'' 
15 U.S.C. 2605(a). This finding cannot be made considering risk alone. 
In promulgating any rule under TSCA section 6(a), the statute requires 
that the EPA Administrator consider:
     The effects of such substance or mixture on health and the 
magnitude of the exposure of human beings to such substance or mixture.
     The effects of such substance or mixture on the 
environment and the magnitude of the exposure of the environment to 
such substance or mixture.
     The benefits of such substance or mixture for various uses 
and the availability of substitutes for such uses.
     The reasonably ascertainable economic consequences of the 
rule, after consideration of the effect on the national economy, small 
business, technological innovation, the environment, and public health. 
15 U.S.C. 2605(c)(1).
    Furthermore, the control measure adopted is to be the ``least 
burdensome requirement'' that adequately protects against the 
unreasonable risk. 15 U.S.C. 2605(a).
    Section 21(b)(4)(B) of TSCA provides the standard for judicial 
review should EPA deny a request for rulemaking under TSCA section 
6(a): ``If the petitioner demonstrates to the satisfaction of the court 
by a preponderance of the evidence that ... there is a reasonable basis 
to conclude that the issuance of such a rule or order is necessary to 
protect health or the environment against an unreasonable risk of 
injury to health or the environment,'' the court shall order the EPA 
Administrator to initiate the requested action. 15 U.S.C. 
2620(b)(4)(B).

III. Disposition of the TSCA Section 21 Petition

A. What is EPA's Response?

    After careful consideration, EPA has denied the petition. A copy of 
the Agency's response, which consists of a letter to the petitioner, is 
available in the docket for this TSCA section 21 petition.

B. What is EPA's Reason for this Response?

    The petition asks EPA to ``establish regulations prohibiting the 
use and distribution in commerce of Hevea brasiliensis baled natural-
rubber for the manufacture of tires, wherein said rubber fails to 
satisfy The American Society for Testing Materials method ASTM D1076-06 
(Category 5),'' because ``Implementation of an EPA regulation that 
guides tire manufacturers to use Hevea brasiliensis baled natural-
rubber that satisfies ASTM D1076-06 (Category 5) may affect the 
incidence of Hevea brasiliensis natural-rubber allergies and allergy 
induced autism.'' According to the petition, ASTM D1076-06 (Category 5) 
``defines Hevea brasiliensis natural-rubber latex having total protein 
content less than 200 [micro]g/dm\2\ and an antigenic Hev-b protein 
content less than 10 [micro]g/dm\2\'' (Ref. 1).
    However, there is at present no ASTM D1076-06 (Category 5). ASTM 
refers to ASTM International (formerly the American Society for Testing 
Materials), which is a voluntary organization that develops consensus 
technical standards for materials, products, systems, and services. See 
http://www.astm.org, ASTM D 1076-06, ``Standard Specification for 
Rubber-Concentrated, Ammonia Preserved, Creamed, and Centrifuged 
Natural Latex,'' is a specification that ``covers requirements for 
first grade concentrated natural rubber latex'' in only four 
categories. An ASTM D1076-06 (Category 5) does not yet exist. See 
http://engineers.ihs.com/document/abstract/SKGGJBAAAAAAAAAA, last 
visited December 9, 2009.
    For the following reasons, the petition does not set forth facts 
sufficient to establish that it is necessary to issue a rule that 
prohibits the use and distribution in commerce of Hevea brasiliensis 
baled natural rubber for the manufacture of tires that has a ``total 
protein content less than 200 [micro]g/dm\2\ and an antigenic Hev-b 
protein content less than 10 [micro]g/dm\2\'' (Ref. 1) in order to 
protect human health or the environment against unreasonable risk of 
injury.
    First, the petitioner has not presented or identified any direct 
evidence that Hevea brasiliensis natural rubber antigens, or any other 
antigens, cause, induce, or affect autism. Based on the evidence 
provided by the petitioner (Exhibit B and the petitioner's publication 
entitled ``Allergies and Autism'') and evidence otherwise available to 
EPA, this idea is an unproven hypothesis (Refs. 1, 5, and 6). In 
``Allergies and Autism,'' the petitioner states that ``[a]llergy 
induced Autism is an area of research wherein immune responses to 
certain environmental proteins, and foodstuff proteins, may affect the 
development and intensity of atypical behaviors within the Autism 
Spectrum.'' Thus, the petitioner recognizes that the allergy-induced-
autism proposition remains indefinite and unproven. Moreover, reviewing 
different paths of research, the petitioner repeatedly characterizes 
``allergy induced autism'' as a ``hypothesis.'' The petitioner also 
asserts that ``research has shown that allergy may play a role in the 
pathogenesis of Autism,'' and cited a study that purported to find ``a 
significant positive association between autistic severity and the 
frequency of allergic manifestations.'' However, the cited study does 
not directly test the allergy-induced-Autism hypothesis, notes that the 
causes of autism are ``an area of significant controversy,'' and only 
concludes that the ``significant positive association between these 
manifestations and important disease characteristics ... may shed light 
on the possible causal role of allergy in some

[[Page 7589]]

autistic children'' (Ref. 5). A recent consensus report published in 
Pediatrics, the official peer-reviewed journal of the American Academy 
of Pediatrics, concludes that a direct cause-and-effect relationship 
between immune dysfunction and Autism Spectrum Disorders has yet to be 
proven (Ref. 6). Based on its controversial nature, the allergy-
induced-Autism hypothesis and the supporting evidence are insufficient 
to sustain a finding of unreasonable risk required to support a 
regulation under TSCA section 6.
    In addition, as noted in the Federal Register notice (Ref. 3) 
denying the petitioner's previous petition, Hevea brasiliensis natural 
rubber latex allergies have already been the subject of considerable 
Federal Government evaluation. For example, the Consumer Protect Safety 
Commission concluded that the incidence of natural rubber latex allergy 
in the general population was very low (below 1%), that many consumer 
products contain natural rubber latex, and that ``in spite of the 
prevalence of [natural rubber latex] in consumer products, there are 
few documented cases of reactions to [natural rubber latex]-containing 
consumer products,'' most of which involved medical devices. See EPA's 
response to the petitioner's previous petition for a more detailed 
discussion (Ref. 3).
    Second, the petition fails to demonstrate that there is a 
sufficient level of exposure to Hevea brasiliensis antigenic 
proteins2 from the use of Hevea brasiliensis baled natural 
rubber in tires to cause adverse effects from this exposure. Available 
data are ambiguous and do not support the position that the general 
population is subject to widespread exposure to natural rubber latex 
proteins from tires. EPA obtained the full article referenced in 
Exhibit A and considered it in light of this petition (Ref. 7). In the 
study, particulates were collected and analyzed from ambient air 
samples from the Denver metropolitan area. The size of the particles 
was determined using optical microscopy, and it was reported that a 
significant portion (58.5%) was in the respirable range. The particles 
were also characterized using chemical solubility tests and mass 
spectrometry. The authors of the study hypothesized that the particles 
represent abraded tire fragments and concluded that their hypothesis 
was supported by the mass spectroscopic, physical, and chemical data. 
In the study, the authors also demonstrated that Hevea brasiliensis 
antigenic proteins can be extracted from rubber tire fragments. The 
authors speculated that airborne tire fragments ``could contribute, 
through direct and indirect mechanisms, to the increase in both latex 
sensitization and asthma,'' but did not investigate the hypothesis or 
demonstrate that airborne tire fragments directly or indirectly 
contribute to an increase in, or have any impact on, latex 
sensitization and asthma. Moreover, the study only showed that Hevea 
brasiliensis antigenic proteins could be extracted from rubber tire 
fragments, not from particles that were collected from air samples.
---------------------------------------------------------------------------

    \2\ ASTM D1076-06 uses the term ``Hevea antigenic protein'' to 
refer to antigenic proteins in natural rubber and its products as 
measured by test method ASTM D6499. EPA uses Hevea brasiliensis 
antigenic proteins throughout this notice to refer to any antigenic 
proteins from Hevea brasiliensis and not just those measured by test 
method ASTM D6499.
---------------------------------------------------------------------------

    ``Allergies and Autism'' describes a study that reports the 
presence of extractable Hevea brasiliensis antigenic proteins in 
ambient samples of sedimented freeway dust and airborne particulate 
matter from two locations within the Los Angeles basin (Ref. 8). 
However, in a subsequent study examining paved road dust and 
atmospheric particulate matter for allergen exposure in three sites 
within the greater Los Angeles area, the same authors reported no Hevea 
brasiliensis antigenic proteins were detected in paved road dust 
samples (Ref. 9). The authors concluded that the different results 
could be explained by ``differences in driving conditions and sampling 
locations for the roadways examined in each of the two studies.'' The 
authors also reported that material collected from guardrails contained 
about 75% rubber particles, but paved road dust collected from the 
center two-thirds of straight sections of city surface streets did not 
contain rubber particles.
    EPA identified another study that investigated whether exposure to 
road traffic in a large city in Germany (Dresden) is associated with 
allergic sensitization to latex in children (Ref. 10). In this study, 
immunoglobulin E (IgE) levels against Hevea brasiliensis antigenic 
proteins and a panel of common aeroallergens were measured in 2,505 
children, ages 5-11, and an analysis was conducted to determine whether 
there was any correlation between latex sensitization and exposure to 
road traffic as measured by parental self-reporting, traffic counts, 
and measurements of benzene. The authors concluded that their data 
suggest exposure to road traffic is not associated with allergic 
sensitization to latex in children.
    Finally, a letter published in Epidemiology, the official, peer-
reviewed journal of the International Society of Environmental 
Epidemiology, reported that ``[o]btaining solid natural rubber (NR) out 
of latex,'' unlike ``production and use of dipped latex products'' used 
in personal products and medical devices, ``involves intensive heating, 
which destroys many, [though] not all, proteins,'' and that, ``[i]n the 
rubber manufacturing industry, exposure to inhalable NR particles can 
be orders of magnitude higher ..., without producing any evidence of 
latex allergies,'' and concluded that, ``[b]ased on these results[,] an 
association between heavy traffic and sensitization to NRL in the 
general population seems to be unlikely'' (Ref. 11). This letter is 
consistent with comments submitted by the Rubber Manufacturers 
Association in response to the petitioner's previous petition to ban 
antigenic natural rubber latex adhesives. According to the Rubber 
Manufacturers Association, natural rubber latex ``proteins in dry 
rubber products [including tires] are largely denatured, diluted, and 
immobilized to a far greater extent than in products formed from liquid 
latex'' and ``most dry rubber products that have been tested have had 
no detectable levels of latex allergens'' (Ref. 12).
    Third, the petition provides little information on the specific 
factors listed in TSCA section 6(c) that must be considered for a TSCA 
section 6 rulemaking. See Unit II.C.
    For example, the petition provides little specific information on 
the magnitude of exposure of human beings or the environment. Exhibit A 
concludes that Hevea brasiliensis latex antigens are extractible from 
rubber tire fragments, which are abundant in urban air samples, but 
provides little factual information on the magnitude of exposure of 
human beings to the Hevea brasiliensis antigenic proteins from the tire 
fragments. See discussion in Unit II.B.1. concerning natural rubber 
latex proteins in tire particles, as referenced in Exhibit B (Ref. 4).
    The petition provides little factual information on the reasonably 
ascertainable economic consequences of prohibiting the use and 
distribution in commerce of Hevea brasiliensis baled natural-rubber in 
tires that does not have a ``total protein content less than 200 
[micro]g/dm\2\ and an antigenic Hev-b protein content less than 10 
[micro]g/dm\2\.'' In ``Allergies and Autism,'' for example, the 
petitioner recounts who are the major natural rubber latex consuming 
and producing countries, the percentage of natural rubber latex 
consumed today, and rates of natural latex consumption in the past 43 
years. However, this information fails to offer specific factual

[[Page 7590]]

information on the ``reasonably ascertainable economic consequences'' 
that would occur as a result of enacting the proposed regulation (Ref. 
4).
    The petition states that ``proteins inherent in Hevea brasiliensis 
baled natural-rubber can be substantially eliminated'' and that ``ultra 
low-protein natural-rubber latex (e.g., Vytex-NRL) that can be used to 
make Hevea brasiliensis baled natural-rubber that satisfies ASTM D 
1076-06 (Category 5)'' is available, but provides little other 
information on the availability and suitability of substitutes. In 
``Allergies and Autism,'' the petitioner reports that non-Hevea 
brasiliensis latex does not provide a suitable substitute. According to 
the petitioner: ``Efforts have been made to commercialize alternative 
latex having inherently lower antigenic protein content (i.e., guayule 
rubber latex and the Russian dandelion), but such materials are 
reported to be higher in cost and presently are available only in 
limited quantities'' and ``both of these materials have their own 
unique set of proteins with potential allergenic behavior not yet 
clearly understood.'' With respect to Vytex, the petitioner reports 
that it ``can be used for making surgical and examination gloves, 
condoms, foam, tubing, breather bags, balloons, adhesives as well as 
many other natural-latex based products across a wide range of 
industries'' (Ref. 4). Vytex does not appear to be a viable substitute 
for use in tires, however, at this time. Vytex was developed and is 
produced by the Vystar Corp. According to the Vystar Corp. website, 
Vytex is Vystar Corp.'s first commercial product and is presently used 
only in Envy condoms, which were introduced commercially only in 
October of 2009. In addition, Vystar Corp.'s webpage focuses on Vytex's 
suitability for the specialty use of medical devices. See http://
www.vytex.com, last visited January 11, 2010.
    Nor does the petition provide evidence showing that prohibiting the 
use of ``Hevea brasiliensis baled natural-rubber'' that does not have a 
``total protein content less than 200 [micro]g/dm\2\ and an antigenic 
Hev-b protein content less than 10 [micro]g/dm\2\'' in the manufacture 
of tires would be the least burdensome requirement to address the 
potential risks the petition identifies.
    Finally, the petition has not demonstrated that a regulation 
prohibiting the use of ``Hevea brasiliensis baled natural-rubber'' that 
does not have a ``total protein content less than 200 [micro]g/dm\2\ 
and an antigenic Hev-b protein content less than 10 [micro]g/dm\2\'' in 
the manufacture of tires is likely to be successful in reducing the 
incidence of latex allergy or autism.
