2-Propenoic Acid, Sodium Salt, Polymer with 2-Propenamide; 
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 2-propenoic acid, sodium salt, polymer 
with 2-propenamide (which is also known as acrylamide-sodium acrylate 
coplymer); when used as an inert ingredient (a carrier) in pesticide 
formulations that are applied to growing crops or raw agricultural 
commodities after harvest. Stockhausen, Inc., 2401 Doyle Street, 
Greensboro, NC 27406 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 an exemption from the 
requirement of a tolerance. This regulation eliminates the need to 
establish a maximum permissible level for residues of 2-propenoic acid, 
sodium salt, polymer with 2-propenamide.

DATES: This regulation is effective August 15, 2001. Objections and 
requests for hearings, identified by docket control number OPP-301158, 
must be received by EPA on or before October 15, 2001.

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 VIII. of the SUPPLEMENTARY 
INFORMATION. To ensure proper receipt by EPA, your objections and 
hearing requests must identify docket control number OPP-301158 in the 
subject line on the first page of your response.

II. Background and Statutory Findings

    In the Federal Register of May 9, 2001 (66 FR 23695) (FRL-6780-8), 
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 1E6281) by Stockhausen, Inc., 2401 Doyle 
Street, Greensboro, NC 27406. This 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 180.1001(c) be amended by 
establishing an exemption from the requirement of a tolerance for 
residues of 2-propenoic acid, sodium salt, polymer with 2-propenamide; 
CAS Reg. No. 25987-30-8.
    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

[[Page 42763]]

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 polymer, 2-propenoic acid, sodium salt, polymer with 2-
propenamide is not a cationic polymer nor is it reasonably anticipated 
to become a cationic polymer in a natural aquatic environment.
    2. 2-Propenoic acid, sodium salt, polymer with 2-propenamide does 
contain as an integral part of its composition the atomic elements 
carbon, hydrogen, and oxygen.
    3. 2-Propenoic acid, sodium salt, polymer with 2-propenamide does 
not contain as an integral part of its composition, except as 
impurities, any element other than those listed in 40 CFR 
723.250(d)(2)(ii).
    4. 2-Propenoic acid, sodium salt, polymer with 2-propenamide is 
neither designed nor can it be reasonably anticipated to substantially 
degrade, decompose, or depolymerize.
    5. 2-Propenoic acid, sodium salt, polymer with 2-propenamide is 
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. 2-Propenoic acid, sodium salt, polymer with 2-propenamide is not 
a water absorbing polymer with a number average molecular weight (MW) 
greater than or equal to 10,000 daltons.
    Additionally, the polymer, 2-propenoic acid, sodium salt, polymer 
with 2-propenamide, also meets as required the following exemption 
criteria specified in 40 CFR 723.250(e).
    7. The polymer's number average MW of 18,000 daltons is greater 
than 10,000 daltons. The polymer contains less than 2% oligomeric 
material below MW 500 and less than 5% oligomeric material below MW 
1,000.
    Thus, 2-propenoic acid, sodium salt, polymer with 2-propenamide 
meets all the criteria for a polymer to be considered low risk under 40 
CFR 723.250. Based on its conformance to the above criteria, no 
mammalian toxicity is anticipated from dietary, inhalation, or dermal 
exposure to 2-propenoic acid, sodium salt, polymer with 2-propenamide.

V. Aggregate Exposures

    For the purposes of assessing potential exposure under this 
exemption, EPA considered that 2-propenoic acid, sodium salt, polymer 
with 2-propenamide 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 MW of 2-propenoic 
acid, sodium salt, polymer with 2-propenamide is 18,000 daltons. 
Generally, a polymer of this size would be poorly absorbed through the 
intact gastrointestinal tract or through intact human skin. Since 2-
propenoic acid, sodium salt, polymer with 2-propenamide 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 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 2-propenoic acid, sodium 
salt, polymer with 2-propenamide share a common mechanism of toxicity 
with any other chemicals. However, 2-propenoic acid, sodium salt, 
polymer with 2-propenamide 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 2-
propenoic acid, sodium salt, polymer with 2-propenamide.

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 safety will be safe for infants and children. Due to the 
expected low toxicity of 2-propenoic acid, sodium salt, polymer with 2-
propenamide, 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 2-propenoic acid, sodium salt, 
polymer with 2-propenamide is an endocrine disruptor.

B. Existing Exemptions from a Tolerance

    There are no other exemptions from the requirement of a tolerance.

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 2-
propenoic acid, sodium salt, polymer with 2-propenamide 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 2-propenoic acid, 
sodium salt, polymer with 2-propenamide 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.

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

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 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 an exemption from the tolerance 
requirement under FFDCA section 408(d) 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). 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 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).

[[Page 42765]]

    For these same reasons, the Agency has determined that this rule 
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. 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 
``major rule'' as defined by 5 U.S.C. 804(2).
