ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 180
[OPP-2003-0079; FRL-7297-8]
Modified Acrylic Polymers; Revision of Tolerance Exemption
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation revises an existing exemption from the
requirement of a tolerance for modified acrylic polymers when used as
an inert ingredient in a pesticide chemical formulation, including
antimicrobial pesticide chemical formulations if such is used in
accordance with good agricultural or manufacturing practices. Alco
Chemical submitted a petition to EPA under the Federal Food, Drug, and
Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of
1996 (FQPA) requesting the revisions to the existing exemption from the
requirement of a tolerance. This regulation eliminates the need to
establish a maximum permissible level for residues of modified acrylic
polymers.
DATES: This regulation is effective April 2, 2003. Objections and
requests for hearings, identified by docket ID number OPP-2003-0079,
must be received on or before June 2, 2003.
ADDRESSES: Written objections and hearing requests may be submitted
electronically, by mail, or through hand delivery/courier. Follow the
detailed instructions as provided in Unit XI. of the SUPPLEMENTARY
INFORMATION.

II. Background and Statutory Findings
In the Federal Register of January 14, 2003 (68 FR 1846) (FRL-7286-
5), EPA issued a notice pursuant to section 408 of the FFDCA, 21 U.S.C.
346a, as amended by the FQPA (Public Law 104-170), announcing the
filing of a pesticide petition (PP 3E6539) by Alco Chemical, 909
Mueller Drive, Chattanooga, TN 37406-0401. That notice included a
summary of the petition prepared by the petitioner. There were no
comments received in response to the notice of filing.
The petition requested that 40 CFR 180.960 be amended by revising
the existing exemption from the requirement of a tolerance for acrylic
polymers composed of one or more of the following monomers: Acrylic
acid, methyl acrylate, ethyl acrylate, butyl acrylate, hydroxyethyl
acrylate, hydroxypropyl acrylate, hydroxybutyl acrylate, carboxyethyl
acrylate, methacrylic acid, methyl methacrylate, ethyl methacrylate,
butyl methacrylate, isobutyl methacyrlate, hydroxyethyl methacrylate,
hydroxypropyl methacrylate, hydroxybutyl methacrylate, lauryl
methacrylate, and stearyl methacrylate with none and/or one or more of
the following monomers: Acrylamide, N-methyl acrylamide, N-
octylacrylamide, maleic anhydride, maleic acid, monoethyl maleate,
diethyl maleate, monooctyl maleate, dioctyl maleate, and their
corresponding sodium, potassium, ammonium, isopropylamine,
triethylamine, monoethanolamine, and/or triethanolamine salts; the
resulting polymer having a minimum number average molecular weight (in
amu), 1,200 by including N,N-dimethyl acrylamide as one of the
monomers. No CAS Reg. No. is associated with this tolerance exemption.
Section 408(c)(2)(A)(i) of the FFDCA allows EPA to establish an
exemption from the requirement for a tolerance (the legal limit for a
pesticide chemical residue in or on a food) only if EPA determines that
the tolerance is ``safe.'' Section 408(c)(2)(A)(ii) of the FFDCA
defines ``safe'' to mean that ``there is a reasonable certainty that no
harm will result from aggregate exposure to the pesticide chemical
residue, including all anticipated dietary exposures and all other
exposures for which there is reliable information.'' This includes
exposure through drinking water and in residential settings, but does
not include occupational exposure. Section 408(b)(2)(C) of the FFDCA
requires EPA to give special consideration to exposure of infants and
children to the pesticide chemical residue in establishing an exemption
from the requirement of a tolerance and to ``ensure that there is a
reasonable certainty that no harm will result to infants and children
from aggregate exposure to the pesticide chemical residue. . .'' and
specifies factors EPA is to consider in establishing an exemption.
III. Inert Ingredient Definition
Inert ingredients are all ingredients that are not active
ingredients as defined in 40 CFR 153.125 and include, but are not
limited to, the following types of ingredients (except when they have a
pesticidal efficacy of their own): Solvents such as alcohols and
hydrocarbons; surfactants such as polyoxyethylene polymers and fatty
acids; carriers such as clay and diatomaceous earth; thickeners such as
carrageenan and modified cellulose; wetting, spreading, and dispersing
agents; propellants in aerosol dispensers; microencapsulating agents;
and emulsifiers. The term ``inert'' is not intended to imply
nontoxicity; the ingredient may or may not be chemically active.
Generally, EPA has exempted inert ingredients from the requirement of a
tolerance based on the low toxicity of the individual inert
ingredients.
IV. Risk Assessment and Statutory Findings
EPA establishes exemptions from the requirement of a tolerance only
in those cases where it can be clearly demonstrated that the risks from
aggregate exposure to pesticide chemical residues under reasonably
foreseeable circumstances will pose no appreciable risks to human
health. In order to determine the risks from aggregate exposure to
pesticide inert ingredients, the Agency considers the toxicity of the
inert in conjunction with possible exposure to residues of the inert
ingredient through food, drinking water, and through other exposures
that occur as a result of pesticide use in residential settings. If EPA
is able to determine that a finite tolerance is not necessary to ensure
that there is a reasonable certainty that no harm will result from
aggregate exposure to the inert ingredient, an exemption from the
requirement of a tolerance may be established.
Consistent with section 408(b)(2)(D) of the FFDCA, EPA has reviewed
the available scientific data and other relevant information in support
of this action and considered its validity, completeness and
reliability and the relationship of this information to human risk. EPA
has also considered available information concerning the variability of
the sensitivities of major identifiable subgroups of consumers,
including infants and children. In the case of certain chemical
substances that are defined as polymers, the Agency has established a
set of criteria to identify categories of polymers that should present
minimal or no risk (see 40 CFR 723.250). Acrylic polymers composed of
one or more of the following monomers: Acrylic acid, methyl acrylate,
ethyl acrylate, butyl acrylate, hydroxyethyl acrylate, hydroxypropyl
acrylate, hydroxybutyl acrylate, carboxyethyl acrylate, methacrylic
acid, methyl methacrylate, ethyl methacrylate, butyl methacrylate,
isobutyl methacyrlate, hydroxyethyl methacrylate, hydroxypropyl
methacrylate, hydroxybutyl methacrylate, lauryl methacrylate, and
stearyl methacrylate
[[Page 15965]]
with none and/or one or more of the following monomers: Acrylamide, N-
methyl acrylamide, N-octylacrylamide, maleic anhydride, maleic acid,
monoethyl maleate, diethyl maleate, monooctyl maleate, dioctyl maleate,
and their corresponding sodium, potassium, ammonium, isopropylamine,
triethylamine, monoethanolamine, and/or triethanolamine salts; the
resulting polymer having a minimum number average molecular weight (in
amu), 1,200 (also referred to as modified acrylic polymers) were
previously determined to meet the set of criteria identifying
categories of polymers that should present minimal or no risk (66 FR
53720; October 24, 2001).
These criteria of 40 CFR 723.250 would continue to be met with the
addition of N,N-dimethyl acrylamide as one of the acrylic polymer
monomers. Therefore, based on its conformance to the criteria for a
polymer to be considered low risk under 40 CFR 723.250, no mammalian
toxicity is anticipated from dietary, inhalation, or dermal exposure to
modified acylic polymers.
V. Aggregate Exposures
For the purposes of assessing potential exposure under this
exemption, EPA considered that modified acrylic polymers could be
present in all raw and processed agricultural commodities and drinking
water, and that non-occupational non-dietary exposure was possible. The
number average molecular weight of modified acrylic polymers is greater
than 1,200 daltons. Generally, a polymer of this size would be poorly
absorbed through the intact gastrointestinal tract or through intact
human skin. Since modified acrylic polymers conform to the criteria
that identify a low risk polymer, there are no concerns for risks
associated with any potential exposure scenarios that are reasonably
foreseeable. The Agency has determined that a tolerance is not
necessary to protect the public health.
VI. Cumulative Effects
Section 408(b)(2)(D)(v) of the FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance or
tolerance exemption, the Agency consider ``available information''
concerning the cumulative effects of a particular chemical's residues
and ``other substances that have a common mechanism of toxicity.'' The
Agency has not made any conclusions as to whether or not modified
acrylic polymers share a common mechanism of toxicity with any other
chemicals. However, modified acrylic polymers conform to the criteria
that identify a low risk polymer. Due to the expected lack of toxicity
based on the above conformance, the Agency has determined that a
cumulative risk assessment is not necessary.
VII. Determination of Safety for U.S. Population
Based on the conformance to the criteria used to identify a low
risk polymer, EPA concludes that there is a reasonable certainty of no
harm to the U.S. population from aggregate exposure to residues of
modified acrylic polymers.
VIII. Determination of Safety for Infants and Children
FFDCA section 408 of the FFDCA provides that EPA shall apply an
additional tenfold margin of safety for infants and children in the
case of threshold effects to account for prenatal and postnatal
toxicity and the completeness of the data base unless EPA concludes
that a different margin of safety will be safe for infants and
children. Due to the expected low toxicity of modified acylic polymers,
EPA has not used a safety factor analysis to assess the risk. For the
same reasons the additional tenfold safety factor is unnecessary.
IX. Other Considerations
A. Endocrine Disruptors
There is no available evidence that modified acylic polymers is an
endocrine disruptor.
B. Existing Exemptions from a Tolerance
An exemption from the requirement of a tolerance exists (see 40 CFR
180.960) for acrylic polymers composed of one or more of the following
monomers: Acrylic acid, methyl acrylate, ethyl acrylate, butyl
acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate, hydroxybutyl
acrylate, carboxyethyl acrylate, methacrylic acid, methyl methacrylate,
ethyl methacrylate, butyl methacrylate, isobutyl methacyrlate,
hydroxyethyl methacrylate, hydroxypropyl methacrylate, hydroxybutyl
methacrylate, lauryl methacrylate, and stearyl methacrylate with none
and/or one or more of the following monomers: Acrylamide, N-methyl
acrylamide, N-octylacrylamide, maleic anhydride, maleic acid, monoethyl
maleate, diethyl maleate, monooctyl maleate, dioctyl maleate, and their
corresponding sodium, potassium, ammonium, isopropylamine,
triethylamine, monoethanolamine, and/or triethanolamine salts; the
resulting polymer having a minimum number average molecular weight (in
amu), 1,200.
C. Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
the Agency is establishing an exemption from the requirement of a
tolerance without any numerical limitation.
D. International Tolerances
The Agency is not aware of any country requiring a tolerance for
modified acylic polymers nor have any CODEX Maximum Residue Levels
(MRLs) been established for any food crops at this time.
X. Conclusion
Accordingly, EPA finds that exempting residues of modified acrylic
polymers from the requirement of a tolerance will be safe.
XI. Objections and Hearing Requests
Under section 408(g) of the FFDCA, as amended by the FQPA, any
person may file an objection to any aspect of this regulation and may
also request a hearing on those objections. The EPA procedural
regulations which govern the submission of objections and requests for
hearings appear in 40 CFR part 178. Although the procedures in those
regulations require some modification to reflect the amendments made to
the FFDCA by the FQPA, EPA will continue to use those procedures, with
appropriate adjustments, until the necessary modifications can be made.
The new section 408(g) of the FFDCA provides essentially the same
process for persons to ``object'' to a regulation for an exemption from
the requirement of a tolerance issued by EPA under new section 408(d)
of the FFDCA, as was provided in the old sections 408 and 409 of the
FFDCA. However, the period for filing objections is now 60 days, rather
than 30 days.
A. What Do I Need to Do to File an Objection or Request a Hearing?
You must file your objection or request a hearing on this
regulation in accordance with the instructions provided in this unit

Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-
0001. In person or by courier, bring a copy to the location of the
PIRIB described in Unit I.B.1. You may also send an electronic copy of
your request via e-mail to: opp-docket@epa.gov. Please use an ASCII
file format and avoid the use of special characters and any form of
encryption. Copies of electronic objections and hearing requests will
also be accepted on disks in WordPerfect 6.1/8.0 or ASCII file format.
Do not include any CBI in your electronic copy. You may also submit an
electronic copy of your request at many Federal Depository Libraries.
B. When Will the Agency Grant a Request for a Hearing?
A request for a hearing will be granted if the Administrator
determines that the material submitted shows the following: There is a
genuine and substantial issue of fact; there is a reasonable
possibility that available evidence identified by the requestor would,
if established resolve one or more of such issues in favor of the
requestor, taking into account uncontested claims or facts to the
contrary; and resolution of the factual issues(s) in the manner sought
by the requestor would be adequate to justify the action requested (40
CFR 178.32).
XII. Statutory and Executive Order Reviews
This final rule establishes an exemption from the tolerance
requirement under section 408(d) of the FFDCA in response to a petition
submitted to the Agency. The Office of Management and Budget (OMB) has
exempted these types of actions from review under Executive Order
12866, entitled Regulatory Planning and Review (58 FR 51735, October 4,
1993). Because this rule has been exempted from review under Executive
Order 12866 due to its lack of significance, this rule is not subject
to Executive Order 13211, Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355,
May 22, 2001). This final rule does not contain any information
collections subject to OMB approval under the Paperwork Reduction Act
(PRA), 44 U.S.C. 3501 et seq., or impose any enforceable duty or
contain any unfunded mandate as described under Title II of the
Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 104-4). Nor
does it require any special considerations under Executive Order 12898,
entitled Federal Actions to Address Environmental Justice in Minority
Populations and Low-Income Populations (59 FR 7629, February 16, 1994);
or OMB review or any Agency action under Executive Order 13045,
entitled Protection of Children from Environmental Health Risks and
Safety Risks (62 FR 19885, April 23, 1997). This action does not
involve any technical standards that would require Agency consideration
of voluntary consensus standards pursuant to section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (NTTAA),
Public Law 104-113, section 12(d) (15 U.S.C. 272 note). Since
tolerances and exemptions that are established on the basis of a
petition under section 408(d) of the FFDCA, such as the exemption in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply. In addition, the Agency has determined that this
action will not have a substantial direct effect on States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government, as specified in Executive Order 13132, entitled Federalism
(64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to
develop an accountable process to ensure ``meaningful and timely input
by State and local officials in the development of regulatory policies
that have federalism implications.'' ``Policies that have federalism
implications'' is defined in the Executive Order to include regulations
that have ``substantial direct effects on the States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government.'' This final rule directly regulates growers, food
processors, food handlers and food retailers, not States. This action
does not alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of the FFDCA. For these same reasons, the Agency
has determined that this rule
[[Page 15967]]
does not have any ``tribal implications'' as described in Executive
Order 13175, entitled Consultation and Coordination with Indian Tribal
Governments (65 FR 67249, November 6, 2000). Executive Order 13175,
requires EPA to develop an accountable process to ensure ``meaningful
and timely input by tribal officials in the development of regulatory
policies that have tribal implications.'' ``Policies that have tribal
implications'' is defined in the Executive Order to include regulations
that have ``substantial direct effects on one or more Indian tribes, on
the relationship between the Federal Government and the Indian tribes,
or on the distribution of power and responsibilities between the
Federal Government and Indian tribes.'' This rule will not have
substantial direct effects on tribal governments, on the relationship
between the Federal Government and Indian tribes, or on the
distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified in Executive Order 13175.
Thus, Executive Order 13175 does not apply to this rule.
XIII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this rule and other
required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of this rule in the Federal Register. This rule is not a
``major rule'' as defined by 5 U.S.C. 804(2).
