                    **Federal Register**
                     of March 24, 2010 (75 FR 14154-14157) (FRL-8815-6), 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 9F7644) by Monsanto Company, 1300 I St., NW., Suite 450 East, Washington, DC 20052. The petition requested that 40 CFR part 180 be amended by replacing the established tolerances for residues of the herbicide, glyphosate, in or on sweet corn, grain with the following: Corn, sweet, kernel plus cob with husk removed at a tolerance level of 3.0 parts per million (ppm) and corn, sweet, forage at a tolerance level of 9.0 ppm. The petition also requested a reduction in the established tolerance for residues of glyphosate and its metabolite (
                    *N-*
                    acetyl-glyphosate) in or poultry meat from 4.0 ppm to 0.1 ppm, as they believe the tolerance level was inadvertently increased when the poultry tolerances were moved from 40 CFR 180.364 (a)(1) to (a)(2). There were no comments received in response to the notice of filing. Based upon review of the data supporting the petition, EPA is revising the requested actions in several respects. EPA has concluded that a tolerance for residues of glyphosate in or on corn, sweet, kernel plus cob with husk removed should be set at 3.5 ppm, not 3.0 ppm. Since the proposed forage tolerance is less than the currently established tolerance for this commodity, EPA has concluded that a revision to the currently established forage tolerance is unnecessary. EPA is also modifying the tolerance expression for 40 CFR 180.364(a)(1) and (a)(2) to clarify the coverage of the tolerance and the compounds to be measured in determining compliance with tolerance levels. The reasons for these changes are explained in Unit IV.C. 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 glyphosate including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with glyphosate 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. Glyphosate is of low acute toxicity following oral, dermal, and inhalation exposure. It is a mild eye irritant, slight skin irritant, and is not a dermal sensitizer in guinea pigs. Inhalation risk assessments are not required based on the low toxicity of the formulation products (toxicity category III or IV) and the physical characteristics of the technical product. An acute dose and endpoint for assessing acute risk have not been selected for any population subgroups because no effect that could be attributed to a single exposure (dose) was observed in oral toxicity studies including the developmental toxicity studies in rats and rabbits. A chronic feeding/carcinogenicity study in rats found no systemic effects in any of the parameters examined (body weight, food consumption, clinical signs, mortality, clinical pathology, organ weights, and histopathology). In a second chronic feeding/carcinogenicity study in rats tested at higher dietary levels, a lowest-observed-adverse-effect level (LOAEL) was identified at 940-milligrams/kilograms/day (mg/kg/day) & 1,183-mg/kg/day (male/female) based on decreased body-weight gains in females and increased incidence of cataracts and lens abnormalities, decreased urinary pH, increased absolute liver weight, and increased relative liver weight/brain weight in males. No evidence of carcinogenicity was found in rats or mice. In a chronic toxicity study in dogs, no systemic effects were found. Acceptable developmental toxicity studies in the rat and rabbit are available, as is an acceptable 2-generation reproduction study in the rat. No significant reproductive and developmental toxic effects were found. A focal tubular dilation of the kidneys was observed in a 3-generation reproductive study on rats at the 30-mg/kg/day high dose treatment level (HDTL), however a 2-generational reproductive study on rats did not observe the same effect at the 1,500-mg/kg/day HDTL, nor were any adverse reproductive effects observed at any dose level. EPA concluded that the focal tubular dilation of the kidneys at the 30-mg/kg/day level was a spurious rather than a glyphosate-related effect. In a prenatal developmental toxicity study in rats, maternal (systemic) effects observed included mortality, increased clinical signs, and reduced body-weight gain at the HDTL (3,500-mg/kg/day). Developmental (fetal) effects were observed only in the high-dose group 
                    ( print page 19703)
                    and included decreases in total implantations/dam and nonviable fetuses/dam, increased number of litters and fetuses with unossified sternebrae, and decreased mean fetal body weights. In a prenatal developmental toxicity study in rabbits, maternal (systemic) effects observed included mortality and clinical signs of toxicity at the HDTL (350-mg/kg/day). In the rabbits, developmental toxicity was not observed at any dose. On the basis of developmental studies in rats and rabbits and reproductive findings in rats, glyphosate exhibited no evidence of increased susceptibility of offspring. Neurotoxicity has not been observed in any of the acute, subchronic, chronic, developmental, or reproductive studies performed with glyphosate. Specific information on the studies received and the nature of the adverse effects caused by glyphosate 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

Human-Health Risk Assessment,” pp. 26-27 in docket ID number EPA-HQ-OPP-2009-0988. 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 (LOC) 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 the NOAEL 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) (a = acute c = chronic) 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 glyphosate used for human risk assessment is shown in Table 1 of this unit.

 C. Exposure Assessment 1. 
                    *Dietary exposure from food and feed uses.*
                     In evaluating dietary exposure to glyphosate, EPA considered exposure under the petitioned-for tolerances as well as all existing glyphosate tolerances in 40 CFR 180.364. EPA assessed dietary exposures from glyphosate 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.
                    ( print page 19704) No such effects were identified in the toxicological studies for glyphosate; therefore, a quantitative acute dietary exposure assessment is unnecessary. ii. 
                    *Chronic exposure.*
                     In conducting the chronic dietary exposure assessment EPA used the food consumption data from the United States Department of Agriculture Continuing Survey of Food Intake by Individuals (USDA CSFII) (1994-1996 and 1998). The chronic analysis assumed tolerance-level residues, 100 percent crop treated (PCT), and Dietary Exposure Evaluation Model (DEEM (version 7.81)) default processing factors and incorporated glyphosate drinking water monitoring data. iii.
                    *Cancer.*
                     Based on the data summarized in Unit III.A., EPA has concluded that glyphosate does not pose a cancer risk to humans. Therefore, a dietary exposure assessment for the purpose of assessing cancer risk is unnecessary. 2. 
                    *Dietary exposure from drinking water.*
                     The Agency used monitoring data from the United States Geological Survey (USGS) National Water-Quality Assessment Program (NAWQA) to calculate drinking water exposure. For chronic dietary risk assessment, the water concentration of value 13.5 parts per million (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). The sweet corn use is not anticipated to result in residential exposure. However, residential exposure is anticipated from the registered broadcast and spot treatment to residential lawns, gardens, and recreational areas including parks and golf courses. Based on the registered residential use patterns, there is a potential for short-term and intermediate-term dermal and inhalation exposures to homeowners who mix and apply products containing glyphosate. Since short- and intermediate-term dermal and inhalation endpoints were not selected, no residential handler/applicator exposure assessment was conducted. Post-application dermal and inhalation exposure assessments were not conducted since short- and intermediate-term dermal and inhalation endpoints were not selected. Based on registered use patterns, toddlers may have short-term post-application incidental oral exposure from hand-to-mouth, object to mouth, and soil ingestion behavior on treated lawns and swimmers may have short-term post-application incidental oral exposures from treated surface water. Exposures and risks from these scenarios were assessed because an applicable endpoint was identified. Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found at 
                    *http://www.epa.gov/​pesticides/​trac/​science/​trac6a05.pdf.* 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 glyphosate to share a common mechanism of toxicity with any other substances, and glyphosate does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that glyphosate 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 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.*
                     There is no quantitative or qualitative evidence of increased susceptibility of rats or rabbit fetuses to 
                    *in utero*
                     exposure in developmental studies. A focal tubular dilation of the kidneys was observed in a 3-generation reproductive study on rats at the 30-mg/kg/day HDTL, however a 2-generational reproductive study on rats did not observe the same effect at the 1,500-mg/kg/day HDTL, nor were any adverse reproductive effects observed at any dose level. A clear NOAEL was established and the chronic reference dose was set at a level well below (~17-fold) this effect. Therefore, the endpoints selected for risk assessment are protective of the effects seen in the 3-generation rat reproduction study. There are no residual uncertainties for pre- or postnatal toxicity. 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 is complete with the exception of recently-required studies on acute and subchronic neuorotoxicity and immunotoxicity. There is no evidence of neurotoxicity in any of the toxicology studies. Accordingly, although an acute and subchronic neurotoxicity studies are now required as part of new data requirements, EPA does not believe that conducting these studies will result in a lower POD than that currently used for overall risk assessment, and therefore, a database uncertainty factor is not needed to account for lack of these studies. ii. The toxicology database for glyphosate does not show any evidence of treatment-related effects on the immune system. The overall weight of evidence suggests that this chemical does not directly target the immune system. Accordingly, although an immunotoxicity study is required as a part of the new data requirements in the 40 CFR part 158 for conventional pesticide registration, EPA does not believe that conducting a functional immunotoxicity study will result in a lower POD than that currently use for overall risk assessment, and therefore, a data base uncertainty factor is not needed to account for lack of this study. iii. There is no quantitative or qualitative evidence of increased susceptibility of rats or rabbit fetuses to 
                    *in utero*
                     exposure in developmental studies. iv. The dietary exposure analysis of exposure to glyphosate in food is conservative as it assumed tolerance level residues and 100 PCT. EPA made conservative (protective) assumptions in the water modeling used to assess exposure to glyphosate in drinking water. EPA used similarly conservative assumptions to assess postapplication exposure of children as well as incidental oral exposure of toddlers. 
                    ( print page 19705)
                    These assessments will not underestimate the exposure and risks posed by glyphosate. 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 aPAD and 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, glyphosate 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 glyphosate from food and water will utilize 12% of the cPAD for children 1-2 years old, the population group receiving the greatest exposure. Based on the explanation in Unit III.C.3., regarding residential use patterns, chronic residential exposure to residues of glyphosate is not expected. 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). Glyphosate is currently 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 with short-term residential exposures to glyphosate. Short-term incidental oral exposure may occur to young children (swimmer and turf non-dietary ingestion) and adults (swimmers). For young children, short-term aggregate exposure includes chronic dietary (food and water) and incidental oral ingestion exposure resulting from the turf use (highest exposure of all possible scenarios). For adults, short-term aggregate exposure includes chronic dietary exposure (food and water) and incidental oral ingestion exposure resulting from the aquatic use (highest exposure of all possible scenarios). See Table 6.0.1 in the document titled “Glyphosate. Section 3 Registration for Application of the Potassium Salt of Glyphosate to Glyphosate-Tolerant Sweet Corn. Human-Health Risk Assessment” in docket ID number EPA-HQ-OPP-2009-0988 for a summary of the short-term aggregate exposures and risk estimates (the populations included represent those with the highest dietary exposures). For glyphosate, the LOC is for MOEs below 100. Since the aggregate MOEs are ≥720, short-term aggregate exposure to glyphosate does not pose a risk of concern. 4. 
                    *Intermediate-term risk.*
                     Since the short-/intermediate-term incidental oral endpoints are identical, the short-term risk assessments are protective of intermediate-term exposure. 5. 
                    *Aggregate cancer risk for U.S. population.*
                     Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, glyphosate is not expected to 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, or to infants and children from aggregate exposure to glyphosate residues. IV. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology (high-performance liquid chromatography (HPLC) equipped with a fluorescence detector method; LOQ = 0.05 ppm) is available to enforce the tolerance expression. 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 U.N. 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 any MRLs for sweet corn commodities; however, it has established an MRL for residues of glyphosate, per se, in/on poultry, meat at 0.05 ppm. The U.S. tolerance of 0.10 ppm for poultry, meat is necessarily higher than the Codex MRL to account for residues of both gyphosate and its metabolite N-acetyl glyphosate. N-acetyl glyphosate is found in genetically modified (GMO) glyphosate-resistant commodities, including corn and soybeans; that are used as feed items for poultry in the U.S. Therefore, it is included in the U.S. tolerance expression for poultry but not the Codex expression, accounting for the difference in the established MRLs. C. Revisions to Petitioned-For Tolerances EPA has concluded that a tolerance for residues of glyphosate in or on corn, sweet, kernel plus cob with husk removed at 3.5 ppm is needed because the highest residue from the field trials was 3.1 ppm. Since the proposed forage tolerance (9 ppm) is less than the currently established tolerance for this commodity (100 ppm), EPA has concluded that a revision to the currently established tolerance is unnecessary. Finally, EPA is revising the tolerance expressions in 40 CFR 180.364(a)(1) and 40 CFR 180.364(a)(2) to clarify the chemical moieties that are covered by the tolerances and specify clearly how compliance with the tolerances is to be measured. V. Conclusion Therefore this regulation changes the established tolerance for residues of glyphosate in or on corn, sweet, grain (at 0.1 ppm) to 3.5 ppm for residues of glyphosate in or on corn, sweet, kernel plus cob with the husk removed. This regulation reduces the established tolerance for residues of glyphosate and 
                    *N-*
                    acetyl-glyphosate in or on poultry, meat from 4.0 ppm to 0.10 ppm. This regulation also changes the tolerance expression for 40 CFR 180.364(a)(1) and (a)(2). 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 
                    ( print page 19706)
                    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 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) (Pub. L. 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). List of Subjects in 40 CFR Part 180 Environmental protection
