II. Petition for Tolerance

In the Federal Register of June 13, 2008 (73 FR 33817) (FRL-8367- 3), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21

U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 8F7334) by the Gowan Company, 370 South Main St., Yuma, AZ 85364. The petition requested that 40 CFR 180.314 be amended by establishing tolerances for residues of the herbicide triallate, (S-2,3,4- trichloroallyl diisopropylthiocarbamate), in or on Bermudagrass hay at 0.2 parts per million (ppm). That notice referenced a summary of the petition prepared by Gowan Company, the registrant, which is available to the public in the docket, http://www.regulations.gov. There were no comments received in response to the notice of filing.

The Gowan Company has requested an amendment to a Section 3 registration under the Federal Insecticide, Fungicide, and Rodenticide

Act (FIFRA) to register a new use on Bermuda grass for grass grown for seed or hay. The petitioner has requested a tolerance for Bermuda grass, hay to support registration of the new use. This petition was filed in conjunction with Gowan's requested amendment to its FIFRA registration.

Based upon review of the data supporting the petition, EPA has determined that the correct commodity name and numerical value for the tolerance proposed in this petition is Bermudagrass, hay at 0.3 ppm.

EPA has also assigned the proposed tolerance in this petition to paragraph 40 CFR 180.314(a), is correcting the tolerance expression to read: ``Tolerances are established for residues of the herbicide (S- 2,3,4-trichloroallyl diisopropylthiocarbamate) and its metabolite 2,3,3-trichloroprop-2-enesulfonic acid (TCPSA) in or on the following food commodity Bermudagrass, hay at 0.3 ppm.'' The reasons for these changes are explained in Unit IV.D.

III. Aggregate Risk Assessment and Determination of Safety

Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish 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....''

Consistent with section 408(b)(2)(D) of FFDCA, and the factors specified in section 408(b)(2)(D) of FFDCA, 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 the petitioned-for tolerances for residues of triallate and its metabolite TCPSA in/on bermudagrass, hay at 0.3 ppm. EPA's assessment of exposures and risks associated with establishing tolerances follows.

A. Toxicological Profile

EPA has evaluated the available toxicity data and considered its 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.

Triallate has a low order of acute toxicity via oral, dermal, and inhalation routes. Triallate is neurotoxic in rats

Page 29960

based on the acute neurotoxicity study, the subchronic neurotoxicity study, the rat multi-generation reproduction study, and the developmental neurotoxicity study. In subchronic studies in rats, the major target organ appears to be the kidney. Following chronic exposure, systemic toxicity in dogs is limited to an increase in liver weight in both sexes, increases in serum alkaline phosphatase in both sexes, and increases in hemosiderm in the spleen. Toxicity in mice included increased absolute liver weight, increased incidence of altered foci of the liver and hematopoiesis in the spleen. In rats, systemic toxicity was manifested as decreased survival in both sexes, decreased body weight and increased adrenal weight in males. In high dose males from the chronic toxicity/carcinogenicity study, the only treatment-related finding at interim sacrifice was linear papillary mineralization. The only treatment-related effect noted in male Syrian hamsters was decreased serum triglycerides.

There was no increased susceptibility to the offspring of rats following in utero exposure in the prenatal developmental toxicity study in rats, the 2-generation reproduction study in rats, or the developmental neurotoxicity study in rats. However, there is evidence of increased susceptibility in the prenatal developmental toxicity study in rabbits. Triallate has been classified as a possible human carcinogen based on hepatocelluar carcinomas in male mice, with a positive trend and borderline significance in female mice and increased incidence of renal tubular cell adenomas in rats. A linear low-dose approach is used to quantify cancer risk to humans. The existing toxicological data for triallate do not show any significant effects on immunological organs or functions.

The Agency has determined that only triallate and its metabolite

TCPSA should be regulated and assessed for dietary exposure in plant commodities. The Agency decided to regulate on the TCPSA metabolite because it is present at more than 10% of the total radioactive residue

(TRR) in the plant metabolism studies, and in the absence of toxicological data for this metabolite, the same toxicity as the parent compound, triallate is assumed.

Specific information on the studies received and the nature of the adverse effects caused by triallate and its metabolite TCPSA 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://www.regulations.gov in document Triallate: Risk Assessment for

Proposed New Use of Triallate as Pre-Emergence Herbicide for Bermuda grass, Case # 824883, pages 32-42 in docket ID number EPA-HQ-OPP-2008- 0386 identified as document EPA-HQ-OPP-2008-0386-0003.

B. Toxicological Endpoints

For hazards that have a threshold below which there is no appreciable risk, a toxicological point of departure (POD) is identified as the basis for derivation of reference values for risk assessment. The POD may be defined as the highest dose at which no adverse effects are observed (the NOAEL) in the toxicology study identified as appropriate for use in risk assessment. However, if a

NOAEL cannot be determined, the lowest dose at which adverse effects of concern are identified (the LOAEL) or a Benchmark Dose (BMD) approach is sometimes used for risk assessment. Uncertainty/safety factors (UFs) are used in conjunction with the POD to take into account uncertainties inherent in the extrapolation from laboratory animal data to humans and in the variations in sensitivity among members of the human population as well as other unknowns. Safety is assessed for acute and chronic dietary risks by comparing aggregate food and water exposure to the pesticide to the acute population adjusted dose (aPAD) and chronic population adjusted dose (cPAD). The aPAD and cPAD are calculated by dividing the POD by all applicable UFs. Aggregate short-, intermediate-

, and chronic-term risks are evaluated by comparing food, water, and residential exposure to the POD to ensure that the margin of exposure

(MOE) called for by the product of all applicable UFs is not exceeded.

This latter value is referred to as the Level of Concern (LOC).

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 greater than that 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 triallate and TCPSA used for human risk assessment can be found at http:// www.regulations.gov in document Triallate: Risk Assessment for Proposed

New Use of Triallate as Pre-Emergence Herbicide for Bermuda grass, Case

# 824883, pages 32-42 in docket ID number EPA-HQ-OPP-2008-0386 identified as document EPA-HQ-OPP-2008-0386-0003.

C. Exposure Assessment 1. Dietary exposure from food and feed uses. In evaluating dietary exposure to triallate and its metabolite TCPSA, EPA considered exposure under the petitioned-for tolerances as well as all existing triallate tolerances in 40 CFR 180.314. EPA assessed dietary exposures from triallate and TCPSA in food as follows: i. Acute exposure. Quantitative acute dietary exposure and risk assessments are performed for a food-use pesticide, if a toxicological study has indicated the possibility of an effect of concern occurring as a result of a 1-day or single exposure.

In estimating acute dietary exposure, EPA used food consumption information from the United States Department of Agriculture (USDA) insert 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII). As to residue levels in food, EPA used field trial data, empirical processing factors and 100 percent crop treated

(PCT) for all commodities. Anticipated residues (AR) were used. All commodities with the exception of succulent peas were blended commodities; therefore, average field trial values were used for these commodities. The acute AR for succulent peas is the highest field trial residue. PCT data were not used. ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA insert 1994-1996 and 1998 CSFII. As to residue levels in food, EPA used field trial data, empirical processing factors and 100 PCT for all commodities. AR were used. All commodities with the exception of succulent peas were blended commodities; therefore, average field trial values were used for these commodities. The chronic AR for succulent peas is the average field trial residue. PCT data were not used. iii. Cancer. To assess cancer risk, EPA used the same assessment as for chronic exposure. iv. Anticipated residue information. Section 08(b)(2)(E) of FFDCA authorizes EPA to use available data and information on the anticipated residue levels of pesticide residues in food and the actual levels of pesticide residues that have been measured in food. If EPA relies on such information, EPA must require pursuant to FFDCA section 408(f)(1) that data be provided 5 years after the tolerance is established, modified, or left in effect, demonstrating that the levels in food are not above the

Page 29961

levels anticipated. For the present action, EPA will issue such data call-ins as are required by FFDCA section 408(b)(2)(E) and authorized under FFDCA section 408(f)(1). Data will be required to be submitted no later than 5 years from the date of issuance of these tolerances. 2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for triallate and TCPSA in drinking water. These simulation models take into account data on the physical, chemical, and fate/ transport characteristics of triallate and TCSPA. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www.epa.gov/oppefed1/models/water/ index.htm.

Based on the Pesticide Root Zone Model /Exposure Analysis Modeling

System (PRZM/EXAMS) and Screening Concentration in Ground Water (SCI-

GROW) models, the estimated drinking water concentrations (EDWCs) of triallate and TCPSA for acute exposures are estimated to be 9.45 parts per billion (ppb) for surface water and 0.21 ppb for ground water.

The estimated EDWCs of triallate and TCPSA for chronic exposures for non-cancer assessments are estimated to be 1.26 ppb for surface water and 0.21 ppb for ground water.

The estimated EDWCs of triallate and TCPSA for chronic exposures for cancer assessments are estimated to be 1.26 ppb for surface water and 0.21 ppb for ground water.

Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model.

For acute dietary risk assessment, the water concentration value of 9.45 ppb was used to assess the contribution to drinking water.

For chronic dietary risk assessment, the water concentration of value 1.26 ppb was used to assess the contribution to drinking water.

For cancer dietary risk assessment, the water concentration of value 1.26 ppb was used to assess the contribution to drinking water. 3. From non-dietary exposure. The term ``residential exposure'' is used in this document to refer to non-occupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets).

Triallate and its metabolite TCPSA are not registered for any specific use patterns that would result in residential exposure. 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 found in 2001 that although studies suggest that the thiocarbamate pesticides (including triallate) share a common metabolic profile and a common toxic effect (neuropathology of the sciatic nerve), insufficient information exists to establish a common mechanism of toxicity for this effect. For the purposes of this tolerance action, therefore, EPA has assumed that triallate does not have a common mechanism of toxicity with other substances. For more information regarding the common mechanism determination for triallate and the other thiocarbamate pesticides see http://www.epa.gov/oppsrrd/ cumulative/thiocarbamate.pdf.

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. A Degree of Concern analysis was performed for triallate and TCPSA because the rabbit developmental study provided evidence of increased susceptibility in the fetus. The purpose of the Degree of Concern analysis was: i. To determine the level of concern for the effects observed when considered in the context of all available toxicity data; and ii. Identify any residual uncertainties after establishing toxicity endpoints and traditional uncertainty factors to be used in the risk assessment.

In the case of triallate and TCPSA, there was no increased susceptibility to the offspring of rats following in utero exposure in the prenatal developmental toxicity study in rats, in the 2-generation reproduction study in rats, or in the developmental neurotoxicity study in rats. However there was evidence of increased susceptibility in the prenatal developmental toxicity study in rabbits. Fetal effects include decreased body weight and increased skeletal variations at 15 mg/kg/ day. However, the rabbit developmental study identified a NOAEL of 5 mg/kg/day for fetal effects, and this NOAEL was selected as the point of departure for the acute dietary risk assessment. The point of departure for chronic dietary exposure (2.5 mg/kg/day) is lower than the NOAEL for fetal effects (observed at 15 mg/kg/day) and is protective of this endpoint, thus there are no residual concerns. 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 1X. That decision is based on the following findings: i. The toxicity database for triallate and its metabolite is adequate for addressing the sensitivity of infant and children to triallate exposure. The toxicity database for triallate is complete with the exception of an immunotoxicity study. The existing subchronic and chronic studies did not indicate that the immune system will be affected by triallate based on hematology, lymphoid organ weights, and histopathology measurements. The effects seen in the chronic study in dogs and the chronic toxicity study in mice in the spleen are related to hematology, but not related to immunotoxicity--they're just manifested in the spleen as well as in other organs. They do not increase concern for immunotoxicity in any way. Thus, the residual concerns for immunotoxicity are low. ii. No quantitative or qualitative increased susceptibility was demonstrated in the fetuses in the prenatal developmental study in rats following in utero exposure, in the offspring in the developmental neurotoxicity study in rats, as well as in the offspring in the 2- generational reproduction study in rats following in utero and/or postnatal exposure to triallate. iii. Although there was some increased susceptibility in the rabbit developmental toxicity study (where the developmental NOAEL of 5 mg/kg/ day was lower than the maternal NOAEL of 15 mg/kg/day), the dose response for this effect has been adequately characterized (see discussion in Unit III.D.2) and the fetal NOAEL was selected as a point of departure for the acute dietary risk assessment. The point

Page 29962

of departure for the chronic dietary assessment (2.5 mg/kg/day) is lower than the NOAEL for fetal effects (observed at 15 mg/kg/day).

Thus, these assessments are protective of potential adverse effects. iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100 PCT, and reliable data from field trial studies and food processing studies. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to triallate and TCPSA in drinking water. There are no residential uses for triallate, therefore no residential exposure is expected from the use of triallate. These assessments will not underestimate the exposure and risks posed by triallate and its metabolite TCPSA.

E. Aggregate Risks and Determination of Safety

EPA determines whether acute and chronic pesticide exposures are safe by comparing aggregate exposure estimates to the aPAD and cPAD.

The aPAD and cPAD represent the highest safe exposures, taking into account all appropriate SFs. EPA calculates the aPAD and cPAD by dividing the POD by all applicable UFs. For linear cancer risks, EPA calculates the probability of additional cancer cases 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 POD to ensure that the MOE called for by the product of all applicable UFs is not exceeded. 1. Acute risk. An acute aggregate risk assessment takes into account exposure estimates from acute dietary consumption of food and drinking water. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food and water to triallate and TCPSA will occupy -\7\ for food and drinking water, which is less than the range of 1 in 1 million

(1 X 10-\6\), the EPA level of concern. 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 residues of triallate and its metabolite TCPSA.

IV. Other Considerations

A. Analytical Enforcement Methodology

Two analytical methods are available for enforcement of tolerances.

They include the current PAM VOL. II method (gas chromatography with electron capture detection (GC/ECD) designated as method A and another

GC/ECD method (designated as Method RES-099-96, Version 2) which may be requested from: Chief, Analytical Chemistry Branch, Environmental

Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905; e-mail address: residuemethods@epa.gov.

B. International Residue Limits

There are no Canadian, Mexican or Codex MRLs established for triallate and its metabolite TCPSA for Bermudagrass, hay, the tolerance established by this rule. Therefore, there are no issues regarding compatibility with respect to the tolerance established for bermudagrass, hay in this rule.

C. Revisions to Petitioned-For Tolerances

Based on residue trial data submitted to the Agency, EPA determined that the proposed tolerance of 0.2 ppm for Bermudagrass, hay was to low. The residue trail data support the establishment of a tolerance of 0.3 ppm on Bermudagrass, hay expressed in the terms of triallate and its metabolite TCPSA.

V. Conclusion

Therefore, tolerances are established for residues of triallate, S- 2,3,4-trichloroallyl diisopropylthiocarbamate and its metabolite 2,3,3- trichloroprop-2-enesulfonic acid (TCPSA), in or on the following food commodity: Bermudagrass, hay at 0.3 ppm.

VI. Statutory and Executive Order Reviews

This final rule establishes tolerances 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 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

Page 29963

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).

VII. 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).
