                    **Federal Register**
                     of July 14, 2006 (71 FR 40103) (FRL-8058-8), 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 4F6889) by E.I. Dupont de Nemours and Company, Inc., Laurel Run Plaza, P. O. Box 80038, Wilmington, DE 19880-0038. The petition requested that 40 CFR 180.439(a) be amended by establishing tolerances 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 grain sorghum (forage, grain, stover) and rice (grain and straw) at 0.05 parts per million (ppm). That notice referenced a summary of the petition prepared by E.I. DuPont de Nemours and Company, Inc, the registrant, that has been included in the public docket. A comment was received in response to the notice of filing from B. Sachau, 15 Elm Street, Florham Park, NJ 07932. The comment and EPA's response is discussed in Unit IV.C.4. During the course of the review the Agency decided to update the commodity listings to agree with current terminology. The commodities are listed as rice, grain; rice, straw; sorghum, grain, forage; sorghum, grain, grain; and sorghum, grain, stover. 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....” EPA performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. For further discussion of the regulatory requirements of section 408 of the FFDCA and a complete description of the risk assessment process, see 
                    *http://www.epa.gov/​fedrgstr/​EPA-PEST/​1997/​November/​Day-26/​p30948.htm*. III. Aggregate Risk Assessment and Determination of Safety Consistent with 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, consistent with section 408(b)(2) of FFDCA, for tolerances for residues of thifensulfuron methyl, (methyl-3-[[[[(4-methoxy-6-methyl-1,3,5,-triazin-2-yl)amino]carbonyl]amino]sulfonyl]-2-thiophenecarboxylate, on rice, grain at 0.05 part per million (ppm); rice, straw at 0.05 ppm; sorghum, grain, forage at 0.05 ppm; sorghum, grain, grain at 0.05 ppm and sorghum, grain, stover at 0.05 ppm. EPA's assessment of exposures and risks associated with establishing the 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. Specific information on the studies received and the nature of the toxic 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 in Unit III.A. of the final rule published in the 
                    **Federal Register**
                     of September 17, 2004 (69 FR 55975)(FRL-7679-). B. Toxicological Endpoints For hazards that have a threshold below which there is no appreciable risk, the dose at which no adverse effects are observed (the NOAEL) from the toxicology study identified as appropriate for use in risk assessment is used to estimate the toxicological level of concern (LOC). However, the lowest dose at which adverse effects of concern are identified (the LOAEL) is sometimes used for risk assessment if no NOAEL 
                    ( print page 13181)
                    was achieved in the toxicology study selected. An uncertainty factor (UF) is applied to reflect 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. The linear default risk methodology (Q*) is the primary method currently used by the Agency to quantify non-threshold hazards such as cancer. The Q* approach assumes that any amount of exposure will lead to some degree of cancer risk, estimates risk in terms of the probability of occurrence of additional cancer cases. More information can be found on the general principles EPA uses in risk characterization at 
                    *http://www.epa.gov/​pesticides/​health/​human.htm*.

 1. 
                    *Dietary exposure from food and feed uses*. Tolerances have been established (40 CFR 180.439) for the residues of thifensulfuron methyl, in or on a variety of raw agricultural commodities. No tolerances for meat, milk, poultry and egg are established. Risk assessments were conducted by EPA to assess 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. The acute dietary analysis was performed for the population subgroup Females 13-49 only. This subgroup is the only one for which an acute dietary endpoint was identified. In conducting the acute dietary exposure assessment EPA used the Dietary Exposure Evaluation Model software with the Food Commodity Intakes Database (DEEM-FCIDTM
                    ), which incorporates food consumption data as reported by respondents in the USDA 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII), and accumulated exposure to the chemical for each commodity. The following assumptions were made for the acute exposure assessments: Tolerance level residues and 100% crop treated (PCT). No empirical processing factors were used. A DEEM (Version 7.81) default processing factor was used for corn syrup. Anticipated residues or estimates of PCT were not used. ii. 
                    *Chronic exposure*
                    . In conducting the chronic dietary exposure assessment EPA used the DEEM-FCIDTM
                    , which incorporates food consumption data as reported by respondents in the USDA 1994-1996 and 1998 Nationwide CSFII, and accumulated exposure to the chemical for each commodity. The following assumptions were made for the chronic exposure assessments: Tolerance level residues and 100 PCT. No empirical processing factors were used. A DEEM (Version 7.81) default processing factor was used for corn syrup. Anticipated residues or estimates of PCT were not used. iii. 
                    *Cancer*. Thifensulfuron methyl is classified as “not likely to be carcinogenic to humans” based on acceptable chronic/carcinogenic studies in rats and mice. Therefore, a cancer exposure assessment was not performed. 2. 
                    *Dietary exposure from drinking water*. The Agency lacks sufficient monitoring exposure data to complete a comprehensive dietary exposure analysis and risk assessment for thifensulfuron methyl in drinking water. Because the Agency does not have comprehensive monitoring data, drinking water concentration estimates are made by reliance on simulation or modeling taking into account data on the physical characteristics of thifensulfuron methyl. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at 
                    *http://www.epa.gov/​oppefed/​models/​water/​index.htm*. Based on the FQPA Index Reservior 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 3.9 parts per billion (ppb) for surface water and 0.27 ppb for ground water. The EDWCs for chronic exposures are estimated to be 1.5 ppb for surface water and 0.27 ppb for ground water. Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model (DEEM-FCID). For the acute dietary risk assessment the annual average concentration in surface water of 3.9 ppb was used. For the chronic dietary risk assessment the annual average concentration in surface water of 1.5 ppb was used. 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, 
                    ( print page 13182)
                    indoor pest control, termiticides, and flea and tick control on pets). Thifensulfuron methyl is not registered for use on any sites that would result in residential exposure. 4. 
                    *Cumulative effects from substances with a common mechanism of toxicity*. Section 408(b)(2)(D)(v) of the 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.” Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, EPA has not made a common mechanism of toxicity finding as to thifensulfuron methyl and 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 not assumed that thifensulfuron methyl has 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 the policy statements released by EPA's Office of Pesticide Programs concerning common mechanism determinations and procedures for cumulating effects from substances found to have a common mechanism on EPA's website at 
                    *http://www.epa.gov/​pesticides/​cumulative*. D. Safety Factor for Infants and Children 1. 
                    *In general*. Section 408 of FFDCA provides that EPA shall apply an additional tenfold 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 data base on toxicity and exposure unless EPA determines based on reliable data that a different margin of safety will be safe for infants and children. Margins of safety are incorporated into EPA risk assessments either directly through use of a MOE analysis or through using uncertainty (safety) factors in calculating a dose level that poses no appreciable risk to humans. In applying this provision, EPA either retains the default value of 10X when reliable data do not support the choice of a different factor, or, if reliable data are available, EPA uses a different additional safety factor value based on the use of traditional uncertainty factors and/or special FQPA safety factors, as appropriate. 2. 
                    *Prenatal and postnatal sensitivity*. There is no evidence in the developmental study in rabbits and two generation reproduction study in rats of increased quantitative or qualitative susceptibility of the offspring after 
                    *in utero*
                     or post-natal exposure to thifensulfuron methyl. The acceptable developmental toxicity in rats revealed increased quantitative susceptibility of the fetus after 
                    *in utero*
                     exposure. Nonetheless there are no residual uncertainties for pre and post natal toxicity because the fetal toxicity seen in the developmental rat study has been well-characterized and the NOAEL relied upon to calculate the chronic RfD is more than an order of magnitude lower than the NOAEL from the developmental rat study. 3. 
                    *Conclusion*. EPA has determined that reliable data show that it would be safe for infants and children to reduce the FQPA safety factor to 1X. That decision is based on the following findings: i. The toxicity database for thifensulfuron methyl is complete. Although the impact of thifensulfuron methyl on the nervous system has not been specifically evaluated in neurotoxicity studies, available toxicology studies in four species (rat, mouse, dog, and rabbit) do not indicate a neurotoxic mode of action for this chemical and there are no concerns from potential developmental neurotoxicity. Therefore, a developmental neurotoxicity is not required for thifensulfuron methyl. ii. As discussed in above Unit III.D.2., there are no concerns or residual uncertainties for pre and/post natal toxicity. iii. There are no residual uncertainties identified in the exposure databases. The dietary food assessments were performed based on 100 PCT and tolerance level residues. Conservative ground water and surface water modeling estimates were used in the risk assessments. These assessments will not underestimate the exposure and risks posed by thifensulfuron methyl. E. Aggregate Risks and Determination of Safety 1. 
                    *Acute risk*. The acute aggregate risk assessment is provided for females 13-50 years old only. The existing data showed no indication that thifensulfuron methyl could cause adverse effects in the general population based upon a single dose. Thus there is no concern for acute dietary exposure to the general population. Using the exposure assumptions discussed in Unit III.C. for acute exposure, the acute dietary exposure from food and water to thifensulfuron methyl will occupy 0.03% of the aPAD at the 95% percentile of exposure for females 13 years and older. EPA does not expect the aggregate exposure to exceed 100% of the aPAD, 2. 
                    *Chronic risk*. Using the exposure assumptions described in Unit III.C. for chronic exposure, EPA has concluded that exposure to thifensulfuron methyl from food and water will utilize <1 % of the cPAD for the U.S. population, <1% of the cPAD for all infants less than 1 year old, and <1% of the cPAD for children 3-5 years old. There are no residential uses for thifensulfuron methyl that result in chronic residential exposure to thifensulfuron methyl. EPA does not expect the aggregate exposure to exceed 100% of the cPAD. 3. 
                    *Short-term risk*. Short-term aggregate exposure takes into account residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Thifensulfuron methyl is not registered for use on any sites that would result in residential exposure. Therefore, the aggregate risk is the sum of the risk from food and water, which does not exceed the Agency's LOC. 4. 
                    *Intermediate-term risk*. Intermediate-term aggregate exposure takes into account residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Thifensulfuron methyl is not registered for use on any sites that would result in residential exposure. Therefore, the aggregate risk is the sum of the risk from food and water, which does not exceed the Agency's LOC. 5. 
                    *Aggregate cancer risk for U.S. population*. Thifensulfuron methyl is classified “as not likely to be a human carcinogen.” Therefore, EPA does not expect thifensulfuron methyl will pose a cancer risk to humans. 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 and to infants and children from aggregate exposure to thifensulfuron methyl residues. IV. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology (including high performance liquid chromatography (HPLC) with photo-conductivity detection and liquid chromatography with detection via electrospray mass spectroscopy) are available to enforce the tolerance

                    *residuemethods@epa.gov*. B. International Residue Limits There are no established or proposed Codex Maximum Residue Levels (MRLs) for residues of thifensulfuron methyl. Canadian and Mexican MRLs have been established for residues of thifensulfuron methyl for several crops. However no MRLs have been established for sorghum, grain, forage; sorghum, grain, grain; sorghum, grain, stover; rice, grain; or rice, straw. C. Response to Comments A comment for thifensulfuron methyl was received from Ms. B. Sachau, 15 Elm Street, Florham Park, NJ 07932. Ms. Sachau stated that any residue of this product in food was dangerous and questioned the availability of testing for this chemical in combination with thousands of other chemicals used in America today. EPA generally does not require companies to conduct studies to evaluate the potential for synergistic effects from exposure to combinations of chemical exposure. Such testing rarely shows any kind of interaction (synergistic or antagonistic), and there are a nearly infinite number of possible combinations, making the cost of indiscriminate testing prohibitively high. Because synergism does not occur often, the scientific community believes that exposure to multiple chemicals is best assessed by looking at the effects caused by each chemical individually. The only exception to that is when people are exposed to multiple chemicals that share a common mechanism of toxicity. Then the effects of exposure to multiple chemicals are expected to be additive, adjusted for the relative toxicity of different chemicals. This is done through Agency cumulative risk assessments which are discussed in Unit III.C.4. of this document. Ms. Sachau did not submit any scientific evidence that supported a revision of Agency conclusions. Based on the Agency risk assessments discussed in Unit III.E. of this document the Agency has concluded that there is a reasonable certainty that no harm will result to the general population and to infants and children from aggregate exposure to thifensulfuron residues. Ms. Sachau did not submit any scientific evidence that supported a revision of Agency conclusions. V. Conclusion Therefore, the tolerances are established for residues of thifensulfuron methyl, (methyl-3-[[[[(4-methoxy-6-methyl-1,3,5,-triazin-2-yl)amino]carbonyl]amino]sulfonyl]-2-thiophenecarboxylate,on rice, grain at 0.05 part per million (ppm); rice, straw at 0.05 ppm; sorghum, grain, forage at 0.05 ppm; sorghum, grain, grain at 0.05 ppm and sorghum, grain, stover at 0.05 ppm. VI. 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 rule has been exempted from review under Executive Order 12866 due to its lack of significance, this rule is not subject to Executive Order 13211, 
                    *Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use*
                     (66 FR 28355, May 22, 2001). 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.*, or 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). 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); or OMB review or any Agency action under Executive Order 13045, entitled 
                    *Protection of Children from Environmental Health Risks and Safety Risks*
                     (62 FR 19885, April 23, 1997). 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). 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. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled 
                    *Federalism*
                    (64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.” This final rule directly regulates growers, food processors, food handlers and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of FFDCA. For these same reasons, the Agency has determined that this rule does not have any “tribal implications” as described in Executive Order 13175, entitled 
                    *Consultation and Coordination with Indian Tribal Governments*
                     (65 FR 67249, November 6, 2000). Executive Order 13175, requires EPA to develop an accountable process to ensure “meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.” “Policies that have tribal implications” is defined in the Executive order to include regulations that have “substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and the Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.” This rule will not have substantial direct effects on tribal governments, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this rule. VII. Congressional Review Act The Congressional Review Act, 5 U.S.C. 801 
                    *et seq.*, as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the 
                    ( print page 13184)
                    agency promulgating the rule must submit a rule report, which includes a copy of the rule, 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). List of Subjects in 40 CFR Part 180 Environmental protection
