II. Petition for Tolerance
In the Federal Register of April 8, 2009 (74 FR 15971) (FRL- 8407-4), 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 9F7523) by IR-4, 500 College Rd. East, Suite 201 W, Princeton, NJ 08540. The petition requested that 40 CFR 180.439 be amended by establishing a tolerance for residues of the herbicide thifensulfuron methyl, (methyl-3-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl) amino] carbonyl] amino] sulfonyl]-2-thiophenecarboxylate), in or on safflower, seed at 0.05 parts per million (ppm). That notice referenced a summary of the petition prepared on behalf of IR-4 by E.I. DuPont de Nemours, 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.
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 tolerance for residues of thifensulfuron methyl on safflower seed at 0.05ppm. EPA's assessment of exposures and risks associated with thifensulfuron methyl 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.
Thifensulfuron methyl has mild to low acute toxicity when administered via the oral, inhalation and dermal routes of exposure. It has moderate to low toxicity with respect to eye and skin irritation and is not a dermal sensitizer. Most findings in the submitted studies related to decreases in body weights, body weight gains, or organ weights (a reflection of the lower body weights compared with control weights). There were increased liver weights in male dogs and increased thyroid/parathyroid weights in female dogs. There were no gross or histopathological changes reported in any of the studies.
In the rat developmental study, there were no maternal effects at the highest dose tested (HDT). The rabbit developmental study showed a decrease in maternal body weights at the HDT. There were no developmental effects at the HDT. In the 2-generation rat reproduction study there were no parental, reproductive or offspring effects. There was an increase in quantitative susceptibility in the rat developmental study, based on decreased mean fetal body weights, and an increase in the incidence of small renal papillae (only at the highest dose level).
Thifensulfuron methyl is classified as “not likely to be carcinogenic to humans,” based on acceptable chronic/carcinogenicity studies in rats and mice at doses that are considered to be adequate, and not excessive for the determination of carcinogenic potential. The available mutagenicity studies in vivo and in vitro show that thifensulfuron methyl is neither mutagenic nor clastogenic.
Neurotoxicity was not observed in the submitted guideline studies. There were Start Printed Page 19274no acute or subchronic neurotoxicity studies available for review. There were also no immunotoxicity studies submitted for review. Immunotoxicity was observed as a decrease in spleen weight in the subchronic rat study. However, this effect was only noted in males, and only at the mid-level dose of 177 mg/kg. The lack of response at the high-level dose, the occurrence in a single sex, the availability of a clear NOAEL, and the absence of immunotoxic effects in the remainder of the database reduce EPA’s concern for immunotoxicity.
Specific information on the studies received and the nature of the adverse effects caused by thifensulfuron methyl 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 “Thifensulfuron Methyl. Human Health Risk Assessment for the Proposed Food/Feed Use of the Herbicide (Associated with Regional Section 3 Registration) on Safflower,” pp. 9-10 in docket ID number EPA-HQ-OPP-2009-0134.
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 thifensulfuron methyl used for human risk assessment is shown in the table of this unit.
|Exposure/Scenario||Point of Departure and Uncertainty/Safety Factors||RfD, PAD, LOC for Risk Assessment||Study and Toxicological Effects|
|Acute dietary (Females 13 - 50 years of age)||NOAEL = 159 milligrams/kilograms/day (mg/kg/day) UFA = 10x UFH = 10x FQPA SF = 1x||Acute RfD = 1.59 mg/kg/day aPAD = 1.59 mg/kg/day||Developmental Oral Toxicity-Rat. LOAEL = 725 mg/kg/day based on decreased mean body weight and increased incidence of small renal papillae|
|Acute dietary (General population including infants and children)||Not applicable.||There were no single dose effects appropriate for acute exposure assessment for the general population.|
|Chronic dietary (All populations)||NOAEL= 4.3 mg/kg/day UFA =10x UFH = 10x FQPA SF 1x||Chronic RfD = 0.043 mg/kg/day cPAD = 0.043mg/kg/day||Carcinogenicity oral toxicity in mice. LOAEL = 128 mg/kg/day based on decreased body weight and body weight gain.|
|Cancer (Oral)||Not likely to be a human carcinogen, based on the lack of evidence of carcinogenicity in rats and mice.|
|UFA = extrapolation from animal to human (interspecies). UFH = potential variation in sensitivity among members of the human population (intraspecies). UFL = use of a LOAEL to extrapolate a NOAEL. UFS = use of a short-term study for long-term risk assessment. UFDB = to account for the absence of data or other data deficiency. FQPA SF = Food Quality Protection Act Safety Factor. PAD = population adjusted dose (a = acute, c = chronic). RfD = reference dose. MOE = margin of exposure. LOC = level of concern.|
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary exposure to thifensulfuron methyl, EPA considered exposure under the petitioned-for tolerance as well as all existing thifensulfuron methyl tolerances in 40 CFR 180.439. EPA assessed dietary exposures from thifensulfuron methyl 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. No such effect was identified for thifensulfuron methyl for the general population. However, EPA identified potential acute effects (decreased mean body weight, and increased incidence of small renal papillae) from pre-natal exposure and thus is assessing exposure and risk for the population subgroup, females 13 - 49 years old.
In estimating acute dietary exposure, EPA used food consumption information from the United States Department of Agriculture (USDA) 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII). As to residue levels in food, EPA used tolerance-level residues, DEEM default processing factors for all processed commodities and assumed 100 percent crop treated (PCT) for all commodities covered by existing or proposed tolerances.
ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA 1994-1996 and 1998 CSFII. As to residue levels in food, EPA used tolerance-level residues, DEEM default processing factors for all processed commodities and assumed 100 PCT for all commodities covered by existing or proposed tolerances.Start Printed Page 19275
iii. Cancer. Based on the data summarized in Unit III.A., EPA has classified thifensulfuron methyl as “not likely to be carcinogenic to humans”. Therefore, a quantitative exposure assessment to evaluate cancer risk is unnecessary.
iv. Anticipated residue and PCT information. EPA did not use anticipated residue or PCT information in the dietary assessment for thifensulfuron methyl. Tolerance level residues and 100 PCT were assumed for all food commodities.
2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for thifensulfuron methyl in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of thifensulfuron methyl. 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 First Index Reservoir Screening Tool (FIRST) and Screening Concentration in Ground Water (SCI-GROW) models, the estimated drinking water concentrations (EDWCs) of thifensulfuron methyl for acute exposures are estimated to be 4.429 parts per billion (ppb) for surface water and 0.0972 ppb for ground water and for chronic exposures for non-cancer assessments are estimated to be 1.5 ppb for surface water and .0972 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 4.429 ppb was used to assess the contribution to drinking water. For chronic dietary risk assessment, the water concentration of value 1.5 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). Thifensulfuron methyl is 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 has not found thifensulfuron methyl to share a common mechanism of toxicity with any other substances, and thifensulfuron methyl does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that thifensulfuron methyl 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
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. The prenatal and postnatal toxicology database for thifensulfuron methyl includes rat and rabbit prenatal developmental toxicity studies and a 2-generation reproduction toxicity study in rats. There was evidence of increased quantitative susceptibility in the rat developmental toxicity study. At the HDT, decreased mean fetal weights, and an increase in incidence of small renal papillae were observed in the absence of maternal toxicity. There was no indication of pre- or post-natal susceptibility in the rabbit developmental or rat reproduction studies.
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 thifensulfuron methyl is complete except for immunotoxicity, acute neurotoxicity and subchronic neurotoxicity testing. Recent changes to 40 CFR part 158 make acute and subchronic neurotoxicity testing (OPPTS Guideline 870.6200) and immunotoxicity testing (OPPTS Guideline 870.7800) required for pesticide registration; however, the existing data are sufficient for endpoint selection for exposure/risk assessment scenarios, and for evaluation of the requirements under the FQPA.
Neurotoxicity was not observed in any of the studies up to the HDT, nor is there any expectation of neurotoxicity based on the mechanism of action. Furthermore, the toxicity database for thifensulfuron methyl does not indicate that the immune system is the primary target organ. Immunotoxicity was observed as a decrease in spleen weight in the subchronic rat study. However, this effect was only noted in males, and only at the mid-level dose of 177 mg/kg. The lack of response in the high-level dose, the occurrence in a single sex, the availability of a clear NOAEL, and the absence of immunotoxic effects in the remainder of the database reduces EPA’s concern for immunotoxicity. The overall weight of evidence suggests that thifensulfuron methyl does not directly target the immune system, and this finding (decrease in spleen weight) may be due to secondary effects of a primary toxicity. Therefore, the Agency does not believe that conducting the acute and subchronic neurotoxicity, and the immunotoxicity studies will result in a lower point of departure than the currently selected endpoints for overall risk assessment, and therefore, a database uncertainty factor is not needed to account for the lack of these studies.
ii. There is no indication that thifensulfuron methyl is a neurotoxic chemical and there is no need for a developmental neurotoxicity study or additional UFs to account for neurotoxicity.
iii. There is evidence that thifensulfuron methyl results in increased susceptibility in in utero rats in the prenatal developmental studies and in young rats in the 2-generation reproduction study; therefore, a degree of concern analysis was performed to determine the level of concern for the effects observed when considered in the context of all available toxicity data and to identify any residual concerns after establishing toxicity endpoints and traditional UF’s to be used in the thifensulfuron methyl risk assessment. In considering the overall toxicity profile and the endpoints and doses selected for the thifensulfuron methyl risk assessment, EPA characterized the degree of concern for the susceptibility observed in the rat developmental and Start Printed Page 192762-generation reproductive studies as low and determined that there are no residual uncertainties for prenatal and/or postnatal toxicity because:
a. The only missing toxicity data for thifensulfuron methyl are the newly required neurotoxicity and immunotoxicity studies; however, no additional UF is needed in the absence of these studies because there is no evidence to indicate that thifensulfuron methyl targets the nervous system or the immune system. Further, EPA has concluded a developmental neurotoxicity study is not required.
b. There are clear NOAELs and LOAELs for the developmental and offspring effects noted in the rat developmental toxicity and in the 2-generation reproduction toxicity studies and the doses and endpoints have been selected from these studies for risk assessment for the relevant exposed populations, ie., pregnant females and children.
iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on conservative assumptions, including 100 PCT and tolerance-level residues. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to thifensulfuron methyl in drinking water. These assessments will not underestimate the exposure and risks posed by thifensulfuron methyl.
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. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food and water to thifensulfuron methyl will occupy less than 1% of the aPAD for females (ages 13 - 49), the population subgroup receiving the greatest exposure.
2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to thifensulfuron methyl from food and water will utilize 1% of the cPAD for children (ages 3 - 5), the population subgroup receiving the greatest exposure. There are no residential uses for thifensulfuron methyl.
3. Short and intermediate-term risk. Short and intermediate-term aggregate exposure takes into account residential exposure plus chronic exposure to food and water (considered to be a background exposure level).
A short and intermediate-term adverse effect was identified; however, thifensulfuron methyl is not registered for any use patterns that would result in short or intermediate-term residential exposure. Short and intermediate-term risk is assessed based on short and intermediate-term residential exposure plus chronic dietary exposure. Because there is no short or intermediate-term residential exposure and chronic dietary exposure has already been assessed under the appropriately protective cPAD (which is at least as protective as the point of departure used to assess short and intermediate-term risk), no further assessment of short or intermediate-term risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating short and intermediate-term risk for thifensulfuron methyl.
4. Aggregate cancer risk for U.S. population. Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, thifensulfuron methyl is not expected to pose a cancer risk to humans.
5. 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 thifensulfuron methyl residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
The following adequate enforcement methodology is available to enforce the tolerance expression: Two High Pressure Liquid Chromatography (HPLC) photo-conductivity detection methods. The methods 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: email@example.com.
B. International Residue Limits
There are no CODEX, Canadian or Mexican maximum residue limits (MRLs) established for residues of thifensulfuron methyl on safflower.
C. Revisions to Petitioned-For Tolerances
EPA revised the tolerance expression in paragraph (a) to clarify:
1. That, as provided in FFDCA section 408(a)(3), the tolerance covers metabolites and degradates of thifensulfuron methyl not specifically mentioned; and
2. That compliance with the specified tolerance levels is to be determined by measuring only the specific compounds mentioned in the tolerance expression.
Therefore, a tolerance is established for residues of thifensulfuron methyl (methyl-3-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl) amino] carbonyl] amino] sulfonyl]-2-thiophenecarboxylate), in or on safflower, seed at 0.05 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 and responsibilities established by Start Printed Page 19277Congress 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).Start List of Subjects
