Acrylic Graft Copolymer, Polyester Block Copolymer and Polyester
Random Copolymer; Tolerance Exemption

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This regulation establishes an exemption from the requirement
of a tolerance for residues of the polymers methyl methacrylate-
methacrylic acid-monomethoxypolyethylene glycol methacrylate copolymer
minimum number average molecular weight (in amu) 2,730, also known as
acrylic graft copolymer; 12-hydroxystearic acid-polyethylene glycol
copolymer minimum number average molecular weight (in amu) 3,690, also
known as polyester block copolymer; and polyethylene glycol-
polyisobutenyl anhydride-tall oil fatty acid copolymer also known as
polyester random copolymer minimum number average molecular weight (in
amu) 2,960, in pesticide formulations applied to growing crops or to
raw agricultural commodities after harvest, or animals. Uniqema,
formerly ICI Surfactants, 3411 Silverside Road, Box 8340 Wilmington, DE
19803, submitted petitions to EPA under the Federal Food, Drug, and
Cosmetic Act, as amended by the Food Quality Protection Act of 1996
requesting exemptions from the requirement of a tolerance for these
copolymers. This regulation eliminates the need to establish a maximum
permissible level for residues of these polymers.

DATES: This regulation is effective February 23, 2000. Objections and
requests for hearings, identified by docket control number OPP-300970,
must be received by EPA on or before April 24, 2000.

ADDRESSES: Written objections and hearing requests may be submitted by
mail, in person, or by courier. Please follow the detailed instructions
for each method as provided in Unit XI. of the SUPPLEMENTARY
INFORMATION. To ensure proper receipt by EPA, your objections and
hearing requests must identify docket control number OPP-300970 in the

II. Background and Statutory Findings

    In the Federal Register of March 17, 1999 (64 FR 13192) (FRL-6066-
7), EPA issued a notice pursuant to section 408 of the Federal Food,
Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a, as amended by the Food
Quality Protection Act (FQPA) (Public Law 104-170) announcing the
filing of pesticide tolerance petitions (PP 8E4987, 8E4988, and 8E4989
) by Uniqema, formerly ICI Surfactants, 3411 Silverside Road, Box 8340
Wilmington, DE 19803. This notice included a summary of the petitions
prepared by the petitioner. There were no comments received in response
to the notice of filing.
    Pesticide petitions 8E4987, 8E4988 and 8E4989 requested that 40 CFR
180.1001(c) be amended by revising the existing tolerance exemptions
for methyl methacrylate-methacrylic acid-monomethoxypolyethylene glycol
methacrylate copolymer (CAS Reg. No. 119724-54-8); 12-hydroxystearic
acid-polyethylene glycol copolymer (CAS Reg. No. 70142-34-6) and
polyethylene glycol-polyisobutenyl anhydride-tall oil fatty acid
copolymer (CAS Reg. No. 68650-28-2), and that 40 CFR 180.1001(e) be
amended by establishing an exemption from the requirement of a
tolerance for residues of these copolymers.
    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) 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) 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 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. The definition of a polymer is given in 40 CFR 723.250(b). The
following exclusion criteria for identifying these low risk polymers
are described in 40 CFR 723.250(d).
    1. The polymers, acrylic graft copolymer; polyester block copolymer
and polyester random copolymer are not cationic polymers nor are they
reasonably anticipated to become cationic polymers in a natural aquatic
environment.
    2. The polymers contain as an integral part of their composition
the atomic elements carbon, hydrogen, and oxygen.
    3. The polymers do not contain as an integral part of their
composition, except as impurities, any element other than those listed
in 40 CFR 723.250(d)(2)(ii).
    4. The polymers are neither designed nor can they be reasonably
anticipated to substantially degrade, decompose, or depolymerize.
    5. The polymers are manufactured or imported from monomers and/or
reactants that are already included on the TSCA Chemical Substance
Inventory or manufactured under an applicable TSCA section 5 exemption.
    6. The polymers are not water absorbing polymers with number
average molecular weights (MW) greater than or equal to 10,000 daltons.
Additionally, the polymers, acrylic graft copolymer; polyester block
copolymer and polyester random copolymer, also meet as required the
following exemption criteria specified in 40 CFR 723.250(e).
    7. The polymer's number average molecular weights (MW) of 2,730,
3,690, and 2,960, respectively are greater than 1,000 and less than
10,000 daltons. The polymers contain less than 10% oligomeric material
below MW 500 and less than 25% oligomeric material below MW 1,000, and
the polymers do not contain any reactive functional groups.
    Thus, the polymers acrylic graft copolymer; polyester block
copolymer and polyester random copolymer meet all the criteria to be
considered low risk polymers under 40 CFR 723.250. Based on their
conformance to the above

[[Page 8869]]

criteria, no mammalian toxicity is anticipated from dietary,
inhalation, or dermal exposure to acrylic graft copolymer; polyester
block copolymer and polyester random copolymer.

V. Aggregate Exposures

    For the purposes of assessing potential exposure under these
exemptions, EPA considered that acrylic graft copolymer; polyester
block copolymer and polyester random copolymer 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
MWs of acrylic graft copolymer; polyester block copolymer and polyester
random copolymer are 2,730, 3,690 and 2,960 daltons, respectively.
Generally, polymers the size of these would be poorly absorbed through
the intact gastrointestinal tract or through intact human skin. Since
acrylic graft copolymer; polyester block copolymer and polyester random
copolymer 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. Since the Agency has
determined that there is a reasonable certainty that no harm will
result from aggregate exposure to acrylic graft copolymer; polyester
block copolymer or polyester random copolymer a tolerance is not
necessary.

VI. Cumulative Effects

    Section 408 (b)(2)(D)(v) of 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 acrylic graft copolymer;
polyester block copolymer or polyester random copolymer share a common
mechanism of toxicity with any other chemicals. However, acrylic graft
copolymer; polyester block copolymer and polyester random copolymer
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
acrylic graft copolymer; polyester block copolymer or polyester random
copolymer.

VIII. Determination of Safety for Infants and Children

    FFDCA section 408 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 acrylic graft copolymer; polyester block
copolymer and polyester random copolymer, 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 acrylic graft copolymer;
polyester block copolymer or polyester random copolymer are endocrine
disruptors.

B. Existing Exemptions from a Tolerance

    Currently in 40 CFR 180.1001(c) methyl methacrylate-methacrylic
acid-monomethoxypolyethylene glycol methacrylate copolymer minium
number average molecular weight (in amu) 18,000; 12-hydroxystearic
acid-polyethylene glycol copolymer (CAS Number 70142-34-6) minium
number average molecular weight (in amu) 5,000; and polyethylene
glycol-polyisobutenyl anhydride-tall oil fatty acid copolymer minium
number average molecular weight (in amu) 5,000 are all exempt from the
requirement of a tolerance when used as a surfactant, dispersing agent,
suspending agent, or related adjuvants.

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
acrylic graft copolymer; polyester block copolymer or polyester random
copolymer nor have any CODEX Maximum Residue Levels (MRLs) been
established for any food crops at this time.

X. Conclusion

    Accordingly, EPA finds that exempting methyl methacrylate-
methacrylic acid-monomethoxypolyethylene glycol methacrylate copolymer
(CAS Reg. No. 119724-54-8) minium number average molecular weight (in
amu) 2,730; 12-hydroxystearic acid-polyethylene glycol copolymer (CAS
Reg. No. 70142-34-6); and polyethylene glycol-polyisobutenyl anhydride-
tall oil fatty acid copolymer (CAS Reg. No. 68650-28-2) 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 of 1996, EPA will continue to use those
procedures, with appropriate adjustments, until the necessary
modifications can be made. The new section 408(g) 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), as was provided in the old FFDCA sections 408 and 409.
However, the period for filing objections is now 60 days, rather than
30 days.

encryption. Copies of electronic objections and hearing requests will
also be accepted on disks in WordPerfect 6.1/8.0 file format 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. Regulatory Assessment Requirements

    This final rule establishes exemptions from the tolerance
requirement under FFDCA section 408(d) in response to petitions
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). 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
prior consultation as specified by Executive Order 13084, entitled
Consultation and Coordination with Indian Tribal Governments (63 FR
27655, May 19, 1998); special considerations as required by Executive
Order 12898, entitled Federal Actions to Address Environmental Justice
in Minority Populations and Low-Income Populations (59 FR 7629,
February 16, 1994); or require 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 FFDCA section 408(d), 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 FFDCA section 408(n)(4).

XIII. Submission to Congress and the Comptroller General

    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

[[Page 8871]]

``major rule'' as defined by 5 U.S.C. 804(2).
