Styrene- Maleic Anhydride Ethyl Amine 

Salt Copolymer; Exemption From the 

Requirement of a Tolerance 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: This regulation establishes an 

exemption from the requirement of a 

tolerance for residues of styrene- maleic 

anhydride ethyl amine salt copolymer 

when used as an inert ingredient in a 

pesticide chemical formulation. S.A. 

Ajinomoto Omnichem N.V., submitted a 

petition to EPA under the Federal Food, 

Drug, and Cosmetic Act (FFDCA), 

requesting an exemption from the 

requirement of a tolerance. This 

regulation eliminates the need to 

establish a maximum permissible level 

for residues of styrene- maleic 

anhydride ethyl amine salt copolymer 

on food or feed commodities when used 

in accordance with these exemptions. 

DATES: This regulation is effective 

September 21, 2021. Objections and 

requests for hearings must be received 

on or before November 22, 2021, and 

must be filed in accordance with the 

instructions provided in 40 CFR part 

178 (see also Unit I.C. of the 

SUPPLEMENTARY INFORMATION).

II. Background and Statutory Findings 

In the Federal Register of March 22, 

2021 (86 FR 15162) (FRL–10021–44), 

EPA issued a document pursuant to 

FFDCA section 408, 21 U.S.C. 346a, 

announcing the receipt of a pesticide 

petition (PP IN–11408) by Wagner 

Regulatory Associates, Inc., on behalf of, 

S.A. Ajinomoto Omnichem N.V., 

Cooppallaan, 91 B–9230, Wetteren, 

Belgium. The petition requested that 40 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 86, No. 180 / Tuesday, September 21, 2021 / Rules and Regulations 52417 

CFR 180.960 be amended by 

establishing an exemption from the 

requirement of a tolerance for residues 

of styrene- maleic anhydride ethyl 

amine salt copolymer. That document 

included a summary of the petition 

prepared by the petitioner and solicited 

comments on the petitioner’s request. 

The Agency did not receive any 

comments in response to the notice of 

filing. 

Section 408(c)(2)(A)(i) of 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 exemption is ‘‘safe.’’ 

Section 408(c)(2)(A)(ii) of 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 

use in residential settings but does not 

include occupational exposure. Section 

408(b)(2)(C) of 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. Risk Assessment and Statutory 

Findings 

EPA establishes exemptions from the 

requirement of a tolerance only in those 

cases where it can be shown 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 FFDCA section 

408(b)(2)(D), 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 expected to 

present minimal or no risk. 

The definition of a polymer is given 

in 40 CFR 723.250(b) and the exclusion 

criteria for identifying these low-risk 

polymers are described in 40 CFR 

723.250(d). Styrene- maleic anhydride 

ethyl amine salt copolymer conforms to 

the definition of a polymer given in 40 

CFR 723.250(b) and meets the following 

criteria that are used to identify low-risk 

polymers. 

1. The polymer is not a cationic 

polymer nor is it reasonably anticipated 

to become a cationic polymer in a 

natural aquatic environment. 

2. The polymer does contain as an 

integral part of its composition at least 

two of the atomic elements carbon, 

hydrogen, nitrogen, oxygen, silicon, and 

sulfur. 

3. The polymer 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. The polymer is neither designed 

nor can it be reasonably anticipated to 

substantially degrade, decompose, or 

depolymerize. 

5. The polymer 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. The polymer is not a water 

absorbing polymer with a number 

average molecular weight (MW) greater 

than or equal to 10,000 daltons. 

7. The polymer does not contain 

certain perfluoroalkyl moieties 

consisting of a CF3¥ or longer chain 

length as listed in 40 CFR 723.250(d)(6). 

Additionally, the polymer also meets 

as required the following exemption 

criteria specified in 40 CFR 723.250(e). 

8. The polymer’s number average MW 

of 1,700 is greater than 1,000 and less 

than 10,000 daltons. The polymer 

contains less than 10% oligomeric 

material below MW 500 and less than 

25% oligomeric material below MW 

1,000, and the polymer does not contain 

any reactive functional groups. 

Thus, styrene- maleic anhydride ethyl 

amine salt copolymer meets the criteria 

for a polymer to be considered low risk 

under 40 CFR 723.250. Based on its 

conformance to the criteria in this unit, 

no mammalian toxicity is anticipated 

from dietary, inhalation, or dermal 

exposure to styrene- maleic anhydride 

ethyl amine salt copolymer. 

IV. Aggregate Exposures 

For the purposes of assessing 

potential exposure under this 

exemption, EPA considered that 

styrene- maleic anhydride ethyl amine 

salt 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 MW of styrene- maleic 

anhydride ethyl amine salt copolymer is 

1,700 daltons. Generally, a polymer of 

this size would be poorly absorbed 

through the intact gastrointestinal tract 

or through intact human skin. Since 

styrene- maleic anhydride ethyl amine 

salt copolymer conforms 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. 

V. Cumulative Effects From Substances 

With a Common Mechanism of Toxicity 

Section 408(b)(2)(D)(v) of FFDCA 

requires that, when considering whether 

to establish, modify, or revoke a 

tolerance, the Agency consider 

‘‘available information’’ concerning the 

cumulative effects of a particular 

pesticide’s residues and ‘‘other 

substances that have a common 

mechanism of toxicity.’’ 

EPA has not found styrene- maleic 

anhydride ethyl amine salt copolymer to 

share a common mechanism of toxicity 

with any other substances, and styrenemaleic anhydride ethyl amine salt 

copolymer does not appear to produce 

a toxic metabolite produced by other 

substances. For the purposes of this 

tolerance action, therefore, EPA has 

assumed that styrene- maleic anhydride 

ethyl amine salt copolymer does not 

have a common mechanism of toxicity 

with other substances. For information 

regarding EPA’s efforts to determine 

which chemicals have a common 

mechanism of toxicity and to evaluate 

the cumulative effects of such 

chemicals, see EPA’s website at http:// 

www.epa.gov/pesticides/cumulative. 

VI. Additional Safety Factor for the 

Protection of Infants and Children 

Section 408(b)(2)(C) of FFDCA 

provides that EPA shall apply an 

additional tenfold margin of safety for 

infants and children in the case of 


lotter on DSK11XQN23PROD with RULES1
52418 Federal Register / Vol. 86, No. 180 / Tuesday, September 21, 2021 / Rules and Regulations 

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 styrene- maleic anhydride 

ethyl amine salt copolymer, EPA has not 

used a safety factor analysis to assess 

the risk. For the same reasons the 

additional tenfold safety factor is 

unnecessary. 

VII. Determination of Safety 

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, including infants and 

children, from aggregate exposure to 

residues of styrene- maleic anhydride 

ethyl amine salt copolymer. 

VIII. 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. 

IX. Conclusion 

Accordingly, EPA finds that 

exempting residues of styrene- maleic 

anhydride ethyl amine salt copolymer 

from the requirement of a tolerance will 

be safe. 

X. Statutory and Executive Order 

Reviews 

This action establishes a tolerance 

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). Because this action 

has been exempted from review under 

Executive Order 12866, this action is 

not subject to Executive Order 13211, 

entitled ‘‘Actions Concerning 

Regulations That Significantly Affect 

Energy Supply, Distribution, or Use’’ (66 

FR 28355, May 22, 2001) or Executive 

Order 13045, entitled ‘‘Protection of 

Children from Environmental Health 

Risks and Safety Risks’’ (62 FR 19885, 

April 23, 1997). This action does not 

contain any information collections 

subject to OMB approval under the 

Paperwork Reduction Act (PRA) (44 

U.S.C. 3501 et seq.), 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). 

Since tolerances and exemptions that 

are established on the basis of a petition 

under FFDCA section 408(d), such as 

the tolerance 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. 

This action directly regulates growers, 

food processors, food handlers, and food 

retailers, not States or Tribes, nor does 

this action alter the relationships or 

distribution of power and 

responsibilities established by Congress 

in the preemption provisions of FFDCA 

section 408(n)(4). As such, the Agency 

has determined that this action will not 

have a substantial direct effect on States 

or Tribal Governments, on the 

relationship between the National 

Government and the States or Tribal 

Governments, or on the distribution of 

power and responsibilities among the 

various levels of government or between 

the Federal Government and Indian 

Tribes. Thus, the Agency has 

determined that Executive Order 13132, 

entitled ‘‘Federalism’’ (64 FR 43255, 

August 10, 1999) and Executive Order 

13175, entitled ‘‘Consultation and 

Coordination with Indian Tribal 

Governments’’ (65 FR 67249, November 

9, 2000) do not apply to this action. In 

addition, this action does not impose 

any enforceable duty or contain any 

unfunded mandate as described under 

Title II of the Unfunded Mandates 

Reform Act (UMRA) (2 U.S.C. 1501 et 

seq.). 

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 

(NTTAA) (15 U.S.C. 272 note). 

XI. Congressional Review Act 

Pursuant to the Congressional Review 

Act (5 U.S.C. 801 et seq.), 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 the rule in the Federal 

Register. This action is not a ‘‘major 

rule’’ as defined by 5 U.S.C. 804(2).
