Sodium 1,4-Dialkyl Sulfosuccinates; 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 sodium 1,4-dialkyl sulfosuccinates 
including sodium 1,4-dihexyl sulfosuccinate (CAS Reg. No. 3006-15-3); 
sodium 1,4-diisobutyl sulfosuccinate (CAS Reg. No. 127-39-9); and 
sodium 1,4-dipentyl sulfosuccinate (CAS Reg. No. 922-80-5) when used as 
an inert ingredient in pesticide formulations for pre-harvest and post-
harvest uses, as well as, for application to animals under 40 CFR 
180.910 and 40 CFR 180.930, respectively. The Joint Inerts Task Force 
(JITF), Cluster Support Team 13 submitted a petition to EPA under the 
Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment 
of an exemption from the requirement of a tolerance. This regulation 
eliminates the need to establish a maximum permissible level for 
residues of the sodium 1,4-dialkyl sulfosuccinates.

DATES: This regulation is effective June 16, 2010. Objections and 
requests for hearings must be received on or before August 16, 2010, 
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. Petition for Exemption

    In the Federal Register of March 19, 2010 (75 FR 13277) (FRL-8813-
2), EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 
346a, announcing the filing of a pesticide petition (PP 9E7647) by the 
Joint Inerts Task Force, Cluster Support Team 13, EPA Company Number 
84949, c/o CropLife America, 1156 15th St., NW., Suite 400, Washington, 
DC 20005. The petition requested that 40 CFR 180.910 and 40 CFR 180.930 
be amended by establishing exemptions from the requirement of a 
tolerances for residues of sodium 1,4-dialkyl sulfosuccinates including 
sodium 1,4-dihexyl sulfosuccinate (CAS Reg. No. 3006-15-3); sodium 1,4-
diisobutyl sulfosuccinate (CAS Reg. No. 127-39-9); and sodium 1,4-
dipentyl sulfosuccinate (CAS Reg. No. 922-80-5) when used as inert 
ingredients in pesticide formulations for pre-harvest and post-harvest 
uses, as well as, for application to animals. For ease of reading this 
document the sodium 1,4-dialkyl sulfosuccinates will be referred to as 
SDSS. That notice referenced a summary of the petition prepared by the 
Joint Inerts Task Force (JITF), Cluster Support Team Number 13 (CST 
13), the petitioner, which is available in the docket, http://
www.regulations.gov. No comments were received in the docket. However, 
the Agency received one comment by e-mail. The comment was received 
from a private citizen who opposed the authorization to sell any 
pesticide that leaves a residue on food. The Agency understands the 
commenter's concerns and recognizes that some individuals believe that 
no residue of pesticides should be allowed. However, under the existing 
legal framework provided by section 408 of the FFDCA EPA is authorized 
to establish pesticide tolerances or exemptions where persons seeking 
such tolerances or exemptions have demonstrated that the pesticide 
meets the safety standard imposed by that statute.
    EPA previously published a final rule to establish a tolerance for 
SDSS under 40 CFR 180.920 in the Federal Register of July 8, 2009 (74 
FR 32433) (FRL-8423-3). That final rule established a tolerance 
exemption for SDSS when used as an inert ingredient in pesticide 
formulations applied to growing crops only.

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. Aggregate Risk Assessment and Determination of Safety

    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 tolerance is ``safe.'' Section 408(b)(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 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 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....''
    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(c)(2)(A) of FFDCA, and the factors 
specified in FFDCA section 408(c)(2)(B), EPA has reviewed the available 
scientific data and other relevant information in support of this 
action. EPA has sufficient data to assess the hazards of and to make a 
determination on aggregate exposure for SDSS including exposure 
resulting from the exemption established by this action. EPA's 
assessment of exposures and risks associated with SDSS follows.

A. Toxicological Profile

    EPA has evaluated the available toxicity data and considered their 
validity, completeness, and reliability as well as the relationship of 
the results of the studies 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.
    SDSS have moderate to low acute oral toxicity and low dermal acute 
toxicity. There was no hazard identified in a combined repeat dose rat 
reproductive/developmental screening study at the limit dose of 1,000 
milligrams/kilogram/day (mg/kg/day) to either parental animals or their 
offspring. There is no concern for neurotoxicity, immunotoxicity or 
carcinogenicity for SDSS.
    Specific information on the studies received and the nature of any 
observed effects caused by SDSS as well as the no-observed-adverse-
effect-level (NOAEL) and the lowest-observed-adverse-effect-level 
(LOAEL) from the toxicity studies can be found at http://

[[Page 34047]]

www.regulations.gov in the document ``Sodium 1,4-Dialkyl 
Sulfosuccinates (JITF CST 13 Inert Ingredients). Human Health Risk 
Assessment to Support Proposed Exemption from the Requirement of a 
Tolerance When Used as Inert Ingredients in Pesticide Formulations'' 
pages 6-8 in docket ID number EPA-HQ-OPP-2008-0739.

B. Toxicological Points of Departure/Levels of Concern

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological points of departure (POD) and levels of 
concern to use in evaluating the risk posed by human exposure to the 
pesticide. For hazards that have a threshold below which there is no 
appreciable risk, the toxicological POD is used as the basis for 
derivation of reference values for risk assessment. PODs are developed 
based on a careful analysis of the doses in each toxicological study to 
determine the dose at which no adverse effects are observed (the NOAEL) 
and the lowest dose at which adverse effects of concern are identified 
(the LOAEL). Uncertainty/safety factors are used in conjunction with 
the POD to calculate a safe exposure level - generally referred to as a 
population-adjusted dose (PAD) or a reference dose (RfD) - and a safe 
margin of exposure (MOE). For non-threshold risks, the Agency assumes 
that any amount of exposure will lead to some degree of risk. Thus, the 
Agency estimates risk in terms of the probability of an occurrence of 
the adverse effect expected in a lifetime. For more information on the 
general principles EPA uses in risk characterization and a complete 
description of the risk assessment process, see http://www.epa.gov/
pesticides/factsheets/riskassess.htm.
    There was no hazard identified in a combined repeated dose toxicity 
study with the reproduction/developmental toxicity screening test in 
rats with SDSS at the limit dose of 1,000 mg/kg/day to either parental 
animals or their offspring. Thus, due to their low potential hazard and 
lack of a hazard endpoint, the Agency has determined that a 
quantitative risk assessment using safety factors applied to a POD 
protective of an identified hazard endpoint is not appropriate.
    No mutagenicity, genotoxicity, or chronic toxicity data have been 
located for any of the SDSS. However, no structural alerts for 
genotoxicity or carcinogenicity were identified in a qualitative 
structure activity relationship (SAR) database, DEREK Version 11. In 
addition, data for similar compounds showed they are not mutagenic or 
carcinogenic. The primary alcohol mammalian metabolites of SDSS have 
been shown to be negative in the in vitro Ames test. Furthermore, a 
structurally similar compound that is also used as an inert ingredient, 
sodium dioctyl sulfosuccinate (CAS Reg. No. 577-11-7) was not 
mutagenic, or carcinogenic in a chronic rat study or a tumor promotion 
study. Based on the above, SDSS are not expected to be carcinogenic.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses and drinking water. 
Since an endpoint for risk assessment was not identified, an exposure 
assessment for SDSS was not conducted. Any possible dietary exposure of 
SDSS from their use as inert ingredients in pesticide products would be 
through consumption of food to which pesticide products containing SDSS 
have been applied and through drinking water (from runoff).
    2. From non-dietary exposure. The term ``residential exposure'' is 
used in this document to refer to non-occupational, non-dietary 
exposure (e.g., textiles (clothing and diapers), carpets, swimming 
pools, and hard surface disinfection on walls, floors, tables).
     Since an endpoint for risk assessment was not identified, a 
quantitative residential exposure assessment for SDSS was not 
conducted. Residential exposures to SDSS may occur as a result of the 
use of pesticide products containing SDSS as inert ingredients (such as 
antimicrobial hard surface cleaners) as well as from other, 
nonpesticidal, residential use products containing SDSS.
    3. 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 SDSS to share a common mechanism of toxicity 
with any other substances, and SDSS does not appear to produce a toxic 
metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has assumed that SDSS 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.

D. Safety Factor for Infants and Children

    Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an 
additional tenfold (10X) 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 database on toxicity and exposure 
unless EPA determines based on reliable data that a different margin of 
safety will be safe for infants and children. This additional margin of 
safety is commonly referred to as the Food Quality Protection Act 
Safety Factor (FQPA SF). In applying this provision, EPA either retains 
the default value of 10X, or uses a different additional safety factor 
when reliable data available to EPA support the choice of a different 
factor.
    The toxicity database for SDSS is adequate for FQPA assessment and 
the potential exposure is adequately characterized given the low 
toxicity of the chemical. There was no hazard identified in a combined 
repeat dose rat reproductive/developmental screening study at the limit 
dose of 1,000 mg/kg/day to either parental animals or their offspring. 
There is no concern for neurotoxicity, immunotoxicity or 
carcinogenicity for SDSS.
    Based on this information, there is no concern, at this time, for 
increased sensitivity to infants and children to SDSS when used as 
inert ingredients in pesticide formulations for pre-harvest and post-
harvest uses, as well as for application to animals, therefore a safety 
factor analysis has not been used to assess risk. For the same reason, 
EPA has determined that an additional safety factor is not needed to 
protect the safety of infants and children.

E. Aggregate Risks and Determination of Safety

     Given the lack of concern for hazard posed by SDSS, EPA concludes 
that there are no dietary or aggregate dietary/non-dietary risks of 
concern as a result of exposure to SDSS in food and water or from 
residential exposure.
    Taking into consideration all available information on SDSS, EPA 
has determined that there is a reasonable certainty that no harm to any 
population subgroup will result from aggregate exposure to SDSS under 
reasonable foreseeable circumstances. Therefore, the establishment of 
an exemption from tolerance under 40 CFR 180.910 and 40 CFR 180.930 for 
residues of sodium 1,4-dialkyl sulfosuccinates including sodium 1,4-
dihexyl sulfosuccinate (CAS

[[Page 34048]]

Reg. No. 3006-15-3); sodium 1,4-diisobutyl sulfosuccinate (CAS Reg. No. 
127-39-9); and sodium 1,4-dipentyl sulfosuccinate (CAS Reg. No. 922-80-
5) when used as an inert ingredient in pesticide formulations for pre-
harvest and post-harvest uses, as well as, for application to animals, 
is safe under FFDCA section 408.

V. Other Considerations

A. 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.

B. International Residue Limits

    The Agency is not aware of any country requiring a tolerance for 
SDSS nor have any CODEX Maximum Residue Levels been established for any 
food crops at this time.

VI. Conclusions

     Therefore, an exemption from the requirement of a tolerance is 
established under 40 CFR 180.910 and 40 CFR 180.930 for sodium 1,4-
dialkyl sulfosuccinates including sodium 1,4-dihexyl sulfosuccinate 
(CAS Reg. No. 3006-15-3); sodium 1,4-diisobutyl sulfosuccinate (CAS 
Reg. No. 127-39-9); and sodium 1,4-dipentyl sulfosuccinate (CAS Reg. 
No. 922-80-5) when used as an inert ingredient in pesticide 
formulations for pre-harvest and post-harvest uses, as well as, for 
application to animals.

VII. Statutory and Executive Order Reviews

    This final rule establishes a tolerance under section 408(d) of 
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 final rule has been 
exempted from review under Executive Order 12866, this final rule 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 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., 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 section 408(d) of FFDCA, such as the exemptions 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 final rule 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 section 408(n)(4) of FFDCA. 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 final rule. In addition, 
this final rule does not 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).
    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).

VIII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report 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 final rule in the Federal 
Register. This final rule is not a ``major rule'' as defined by 5 
U.S.C. 804(2).
