**N-(n-octyl)-2-pyrrolidone; 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 N-(n-octyl)-2- pyrrolidone (CAS Reg. No. 2687–94–7) when used as an inert ingredient(solvent) in formulations of pyraflufenethyl herbicide at a maximum concentration of 20% weight. Wagner Regulatory Associates on behalf of Nichino America, Inc. 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 maximumpermissible level for residues of N-(noctyl)-2-pyrrolidone.

**DATES :**  This regulation is effective February 26, 2014. Objections and requests for hearings must be received on or before April 28, 2014, and must

II. Petition for Exemption

In the Federal Register of February 27, 2013 (78 FR 13295) (FRL–9380–2), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 346a, announcing the filing of a pesticide petition (IN–10541) by Nichino America, Inc. 4550 New Linden Hill Road, Suite 501, Wilmington, DE 19808. The petition requested that 40 CFR 180.1130 be amended by establishing an exemption from the requirement of a tolerance for residues of N-(n-octyl)-2- pyrrolidone (CAS Reg. No. 2687–94–7) when used as an inert ingredient(solvent) in formulations of pyraflufenethyl herbicide at a maximum concentration of 20% weight. That document referenced a summary of the petition prepared by Wagner Regulatory Associates, Inc. 7217 Lancaster Pike, Suite A, P.O. Box 640, Hockessin, Delaware 19707, the petitioner, which is available in the docket, http:// www.regulations.gov. There were no comments received in response to the notice of filing.

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 FFDCA section 408(c)(2)(A), 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 N-(n-octyl)-2- pyrrolidone including exposure resulting from the exemption established by this action. EPA’s assessment of exposures and risks associated with N-(n-octyl)-2- pyrrolidone 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. Specific
information on the studies received and
the nature of the adverse effects caused by N-(n-octyl)-2-pyrrolidone as well as
the no-observed-adverse-effect-level(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the toxicity studies are discussed in this

unit.

Based on the results of acute toxicity studies in rats, N-(n-octyl)-2-pyrrolidone is classified as having low acute toxicity
via the oral and dermal routes of exposure. It is a dermal irritant and a
dermal sensitizer.

In mammals, the primary target is the liver. In subchronic feeding studies in rats and dogs, N-(n-octyl)-2-pyrrolidone generally caused increases in both absolute and relative liver weights along with reduction in body weight gain/food consumption and changes in hematological and biochemical parameters. No chronic toxicity study is
available.

In a developmental toxicity study in rats with N-(n-octyl)-2-pyrrolidone,
there was no evidence of increased susceptibility in fetuses as toxic effects were observed only at the highest dose tested, 800 milligrams/kilograms/day (mg/kg/day), in which dams exhibited ruffled fur, ventral recumbency, somnolence, apathy, dyspnea and
comatose state. Other adverse effects
observed were a reduction in food consumption and slight body weight loss during the first days of dosing and reduced corrected body weight gain. Developmental effects such as reduced body weight and delay in skeletal ossification were observed only in the presence of maternal toxicity. No reproductive toxicity, immunotoxicity or neurotoxicity data are available for N- (n-octyl)-2-pyrrolidone,

There were three genotoxicity studies available in the database for N-(n-octyl)- 2-pyrrolidone. An Ames test, a mouse


### 10680 Federal Register / Vol. 79, No. 38 / Wednesday, February 26, 2014 / Rules and Regulations

lymphoma assay and a mouse micronucleus test all showed negative results for genotoxicity of N-(n-octyl)-2- pyrrolidone.

No carcinogenicity studies were available in the database for N-(n-octyl)- 2-pyrrolidone. The Agency used a qualitative structure activity relationship (SAR) database, DEREK11,
to determine if there were structural alerts for potential carcinogenicity for N-(n-octyl)-2-pyrrolidone. No structural alerts for carcinogenicity were identified for N-(n-octyl)-2-pyrrolidone. In the absence of any structural alerts and lack of mutagenicity concerns, N-(n-octyl)-2- pyrrolidone is not expected to be carcinogenic.

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.

A summary of the toxicological endpoints for N-(n-octyl)-2-pyrrolidone used for human risk assessment is given
below:

1. Acute dietary (all populations).
There were no adverse effects observed attributable to a single dose for the general population (including infants and children) or females 13–49 years of

age.

2. Chronic dietary (all populations). The chronic population adjusted dose (cPAD) was established based on the NOAEL (30 mg/kg/day) from a 90-day oral toxicity study in dogs. The adverse effects seen in this study were several statistically significant changes in hematology and clinical chemistry parameters and statistically significant
dose-related increases in both absolute and relative liver weights at the LOAEL of 90 mg/kg/day. A Food Quality Protection Act (FQPA) safety factor/ database uncertainty factor of 3X is utilized for dietary risk assessment.

3. Dermal, short-term (1–30 days). The level of concern (LOC) for short-term dermal exposure is a Margin of Exposure (MOE) of 300 between estimated human exposure and the NOAEL (30 mg/kg/day) from the 90-day oral toxicity study in dogs. An FQPA safety factor/database uncertainty factor of 3X is utilized for dermal, short-term,

assessment.

4. Inhalation, short-term (1–30 days).The level of concern (LOC) for shortterm inhalation exposure is a MOE of 300 between estimated human exposure and the NOAEL (30 mg/kg/day) from the 90-day oral toxicity study in dogs. An FQPA safety factor/database uncertainty
factor of 3X for the short-term inhalation

assessment.

Quantification of cancer risk is not appropriate since there are no concerns for cancer based on SAR analysis of N- (n-octyl)-2-pyrrolidone.

C. Exposure Assessment

1. Dietary exposure from food and feed uses. In evaluating dietary exposure to N-(n-octyl)-2-pyrrolidone, EPA considered exposure under the proposed exemption from the requirement of a tolerance. EPAassessed dietary exposures from N-(noctyl)-2-pyrrolidone in food as follows:

In conducting the chronic dietary exposure assessment using the Dietary Exposure Evaluation Model/Food Commodity Intake Database (DEEM– FCID) TM , Version 3.16, EPA used food consumption information from the U.S. Department of Agriculture’s National
Health and Nutrition Examination Survey, What we eat in America, (NHANES/WWEIA). This dietary survey
was conducted from 2003 to 2008. As to residue levels in food, no residue data were submitted for N-(n-octyl)-2- pyrrolidone. In the absence of specific residue data, EPA has developed an approach which uses surrogate information to derive upper bound exposure estimates for the subject inert ingredient. Upper bound exposure estimates are based on the highest tolerance for a given commodity from a list of high-use insecticides, herbicides, and fungicides. A complete description of the general approach taken to assess inert ingredient risks in the absence of
residue data is contained in the memorandum entitled ‘‘Alkyl Amines Polyalkoxylates (Cluster 4): Acute and Chronic Aggregate (Food and Drinking Water) Dietary Exposure and Risk Assessments for the Inerts.’’ (D361707, S. Piper, 2/25/09) and can be found at http://www.regulations.gov in docket ID number EPA–HQ–OPP–2008–0738.

In the case of N-(n-octyl)-2- pyrrolidone, EPA made specific adjustments to the dietary exposure
assessment to account for the use limitations of N-(n-octyl)-2-pyrrolidone as an inert ingredient in cotton defoliant formulations containing thidiazuron and diuron as active ingredients as well as the proposed use as an inert ingredient in formulations of pyraflufen ethyl herbicide at a maximum concentration of 20% weight.

2. Dietary exposure from drinking

water. For the purpose of the screening level dietary risk assessment to support this request for an exemption from therequirement of a tolerance for N-(noctyl)-2-pyrrolidone, a conservative drinking water concentration value of 100 parts per billion (ppb) based on screening level modeling was used to assess the contribution to drinking water for the chronic dietary risk assessments for parent compound. These values were directly entered into the dietary exposure model.

3. From non-dietary exposure. The term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure (e.g., textiles (clothing and diapers), carpets, swimming pools, and hard surface disinfection on walls, floors, tables).

The proposed use of N-(n-octyl)-2- pyrrolidone is as an inert ingredient in pyraflufen ethyl formulations which have uses resulting in potential residential exposures. A screening level residential exposure and risk
assessment was conducted based on the use pattern and application rates of pyraflufen ethyl products.

EPA assessed residential exposure using the following assumptions: All residential exposures are considered
short-term in duration. The residential
handler assessment included short-term exposures via the dermal and inhalation routes from treating golf courses, ornamental turf lawns, road sides, parksand sports fields. In terms of postapplication exposure, there is the potential for dermal post-application exposure for individuals as result of being in an environment that has been previously treated with N-(n-octyl)-2- pyrrolidone. Short-term dermal exposures were assessed for adults,


### 10681 Federal Register / Vol. 79, No. 38 / Wednesday, February 26, 2014 / Rules and Regulations

children 1–2 and adult/child golfer. The scenarios used in the aggregate
assessment were those that resulted in the highest exposures.

4. 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 N-(n-octyl)-2- pyrrolidone to share a common mechanism of toxicity with any other substances, and N-(n-octyl)-2- pyrrolidone does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that N-(n-octyl)-2-pyrrolidone
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 Web site at http:// www.epa.gov/pesticides/cumulative.

D. Safety Factor for Infants and
Children

1. In general. 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 FQPA Safety Factor (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.

2. Prenatal and postnatal sensitivity. No evidence of increased susceptibility was seen in the developmental toxicity study on N-(n-octyl)-2-pyrrolidone. The maternal and developmental toxicity NOAEL was 200 mg/kg bw/day based on reduced body weight gain in dams and mean fetal body weight and delay
in skeletal ossification at the LOAEL of 800 mg/kg bw/day. No reproductive toxicity study is available N-(n-octyl)-2- pyrrolidone.

3. Conclusion. EPA has determined that reliable data show the safety of
infants and children would be adequately protected if the FQPA SF were reduced to 3X for all scenarios. That decision is based on the following findings:

i. The toxicity database for N-(noctyl)-2-pyrrolidone consists of 90-day oral toxicity studies in rats and dogs, several mutagenicity studies and a developmental toxicity study. While there are no reproductive, neurotoxicityand chronic toxicity studies for N-(noctyl)-2-pyrrolidone, there is no evidence of effects on reproductive parameters or of any effects suggestive of neurotoxicity from the available subchronic studies. Additionally, the most sensitive endpoint selected seen in the 90-day dog oral toxicity study is based on hematological and clinical chemistry parameters; increases in both absolute and relative liver weights; and reduction in body weight gain/food consumption—effects which are not expected to be progressive and for which the resultant exposure assessment is likely to be protective of chronic effects and characterize toxicity potential of N-(n-octyl)-2-pyrrolidone. Although additional data are unlikely to indicate more sensitive effects, EPA has retained a FQPA factor of 3X as a database uncertainty factor. No inhalation toxicity studies were available in the database; however, the only potential inhalation exposure to N- (n-octyl)-2-pyrrolidone is to pesticide applicators, and, even assuming that such exposure has some relevance to decisions on the FQPA safety factor, the inhalation exposure to N-(n-octyl)-2- pyrrolidone is negligible in comparison to exposure under other pathways. In these circumstances, neither retention or removal of the FQPA safety factor would have a meaningful impact on
assessment of risk from inhalation

exposure.

ii. No evidence of immunotoxicity
was observed in the available database. Slight change in the clinical pathological parameters (decreases in albumin/globulin ratio and globulin levels) were not considered as an indication of an immunotoxic response since no effects on blood lymphocytes and no adverse findings in the spleen and thymus. Therefore, an immunotoxicity study is not required.

iii. There are no residual uncertainties identified in the exposure databases. As described earlier, EPA used worst case assumptions for the dietary food exposure assessment. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to N-(n-octyl)- 2-pyrrolidone in drinking water. EPA used similarly conservative assumptions to assess residential post application exposure of children as well as incidental oral exposure of children
1–2. These assessments will not underestimate the exposure and risks posed by N-(n-octyl)-2-pyrrolidone.

E. Aggregate Risks and Determination of Safety

EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate PODs to ensure that an adequate MOE

exists.

1. Acute risk. An acute aggregate risk
assessment takes into account acute exposure estimates from dietary consumption of food and drinking water. No adverse effect resulting from a single oral exposure was identified and no acute dietary endpoint was selected. Therefore, N-(n-octyl)-2- pyrrolidone is not expected to pose an
acute risk.

2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to N-(n-octyl)-2- pyrrolidone from food and water will utilize 59.37% of the cPAD for children 1–2 years old, the population group receiving the greatest exposure. The chronic dietary exposure estimates for the total U.S. population was 14.31%.

3. Short-term risk. Short-term aggregate exposure takes into account short-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). N-(n-octyl)-2- pyrrolidone is currently used as an inert ingredient in pesticide products that are registered for uses that could result in short-term residential exposure, and the Agency has determined that it is appropriate to aggregate chronic exposure through food and water withshort-term residential exposures to N-(noctyl)-2-pyrrolidone.

Using the exposure assumptions
described in this unit for short-term exposures, EPA has concluded the combined short-term food, water, and residential exposures result in aggregate MOEs of 1,122 for adults and 291 for
children 1–2. EPA’s level of concern for N-(n-octyl)-2-pyrrolidone is a MOE of 300 or below, however these MOEs are not of concern based on the highly conservative assumptions made regarding residential and dietary exposures to N-(n-octyl)-2-pyrrolidone.


### 10682 Federal Register / Vol. 79, No. 38 / Wednesday, February 26, 2014 / Rules and Regulations

4. Intermediate-term risk. Intermediate-term residential aggregate exposure takes into account intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Pyraflufen ethyl is not currently registered for uses that could
result in intermediate-term residential exposure so an intermediate term risk assessment for N-(n-octyl)-2-pyrrolidone was not performed. There are also no
intermediate-term adverse effects identified and therefore N-(n-octyl)-2- pyrrolidone is not expected to pose an
intermediate-term risk.

5. Aggregate cancer risk for U.S. population. N-(n-octyl)-2-pyrolidone is not expected to be carcinogenic.

6. Determination of safety. Based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to the general population or to infants and children from aggregate exposure to N-(n-octyl)- 2-pyrrolidone residues.

V. Other Considerations

A. Analytical Enforcement Methodology

An analytical method is not required for enforcement purposes since the Agency is not establishing a numerical tolerance for residues of N-(n-octyl)-2- pyrrolidone in or on any food commodities. EPA is establishing a limitation on the amount of N-(n-octyl)- 2-pyrrolidone that may be used in pesticide formulations.

The limitation will be enforced through the pesticide registration process under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), 7 U.S.C. 136 et seq. EPA will not register any pesticide for sale or distribution containing pyraflufen ethyl as an active ingredient with concentrations of N-(n-octyl)-2- pyrrolidone exceeding 20% by weight of the pesticide formulation.

B. International Residue Limits

In making its tolerance decisions, EPA
seeks to harmonize U.S. tolerances with
international standards whenever possible, consistent with U.S. food safety standards and agricultural practices. EPA considers the
international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). The Codex Alimentarius is a joint United Nation Food and Agriculture Organization/World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing
from the Codex level. The Codex has not established a MRL for N-(n-octyl)-2- pyrrolidone.

VI. Conclusions

Therefore, an exemption from the requirement of a tolerance is established under 40 CFR 180.1130 for N-(n-octyl)- 2-pyrrolidone (CAS Reg. No. 2687–94– 7) when used as an inert ingredient(solvent) in formulations of pyraflufenethyl herbicide at a maximum concentration of 20% by weight.

VII. Statutory and Executive Order

Reviews

This final rule 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 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 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 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 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 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) (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 of 1995 (NTTAA) (15 U.S.C. 272 note).

VIII. Congressional Review Act

II. Background

In the Federal Register of July 25, 2012 (77 FR 43562) (FRL–9353–6), the EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance petition (PP 2F8014) by Vestaron Corporation, 4717 Campus Drive, Ste. 1200, Kalamazoo, MI 49008. The petition requested that 40 CFR part 180 be amended by establishing an exemption from the requirement of a tolerance for residues of GS-omega/ kappa-Hxtx-Hv1a. That document referenced a summary of the petition prepared by the petitioner Vestaron Corporation, which is available in the docket, http://www.regulations.gov. Nocomments to the petition for GS-UACTX-Hv1a-SEQ2 tolerance exemption
were received. A correction for the name of the active ingredient was published in the Federal Register of December 18, 2013 (78 FR 76589) (FRL– 9904–17). The active ingredient,previously known as GS-U-ACTX-Hv1aSEQ2, was revised to GS-omega/kappaHxtx-Hv1a, based on acceptable nomenclature for naming peptide toxins from spiders.
