II. Background and Statutory Findings
EPA, on its own initiative, in accordance with sections 408(e) and 408(l)(6) of FFDCA, 21 U.S.C. 346a(e) and 346a(1)(6), is establishing time-limited tolerances for residues of the herbicide nicosulfuron, in or on Bermudagrass, forage and Bermudagrass, hay at 10 parts per million (ppm) and 25 (ppm) respectively. These time-limited tolerances expire and are revoked on December 31, 2011. EPA will publish a document in the Federal Register to remove the revoked tolerances from the Code of Federal Regulations (CFR).
Section 408(l)(6) of FFDCA requires EPA to establish a time-limited tolerance or exemption from the requirement for a tolerance for pesticide chemical residues in food that will result from the use of a pesticide under an emergency exemption granted by EPA under section 18 of FIFRA. Such tolerances can be established without providing notice or period for public comment. EPA does not intend for its actions on FIFRA section 18 related time-limited tolerances to set binding precedents for the application of section 408 of FFDCA to other tolerances and exemptions. Section 408(e) of FFDCA allows EPA to establish a tolerance or an exemption from the requirement of a tolerance on its own initiative, i.e., without having received any petition from an outside party.
Section 18 of FIFRA authorizes EPA to exempt any Federal or State agency from any provision of FIFRA, if EPA determines that “emergency conditions exist which require such exemption.” EPA has established regulations governing such emergency exemptions in 40 CFR part 166.
III. Emergency Exemption for Nicosulfuron on Bermudagrass Forage and Hay and FFDCA Tolerances
The Texas and Oklahoma Departments of Agriculture requested emergency exemptions for use of nicosulfuron on Bermudagrass and hay to control field sandbur species, and issued crisis exemptions for this use pursuant to 40 CFR part 166, subpart C of FIFRA. The states provided information indicating that sandbur species is a serious pest that commonly infests Bermudagrass and hay.
As part of its evaluation of the emergency exemption applications, EPA assessed the potential risks presented by residues of nicosulfuron in or on Bermudagrass, forage and Bermudagrass, hay. In doing so, EPA Start Printed Page 8258considered the safety standard in section 408(b)(2) of FFDCA, and EPA decided that the necessary tolerances under section 408(l)(6) of FFDCA would be consistent with the safety standard and with FIFRA section 18. Consistent with the need to move quickly on the emergency exemptions in order to address urgent non-routine situations and to ensure that the resulting food is safe and lawful, EPA is issuing these tolerances without notice and opportunity for public comment as provided in section 408(l)(6) of FFDCA. Although these time-limited tolerances expire and are revoked on December 31, 2011, under section 408(l)(5) of FFDCA, residues of the pesticide not in excess of the amounts specified in the tolerances remaining in or on Bermudagrass, forage and Bermudagrass, hay after that date will not be unlawful, provided the pesticide was applied in a manner that was lawful under FIFRA, and the residues do not exceed a level that was authorized by these time-limited tolerances at the time of that application. EPA will take action to revoke these time-limited tolerances earlier if any experience with, scientific data on, or other relevant information on this pesticide indicate that the residues are not safe.
Because these time-limited tolerances are being approved under emergency conditions, EPA has not made any decisions about whether nicosulfuron meets FIFRA's registration requirements for use on Bermudagrass, forage and Bermudagrass, hay or whether permanent tolerances for this use would be appropriate. Under these circumstances, EPA does not believe that these time-limited tolerance decisions serve as a basis for registration of nicosulfuron by a State for special local needs under FIFRA section 24(c). Nor do these tolerances serve as the basis for persons in any States other than Texas and Oklahoma to use this pesticide on the applicable crops under FIFRA section 18 absent the issuance of an emergency exemption applicable within that State. For additional information regarding the emergency exemptions for nicosulfuron, contact the Agency's Registration Division at the address provided under FOR FURTHER INFORMATION CONTACT.
IV. 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 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 expected as a result of these emergency exemption requests and the time-limited tolerances for residues of nicosulfuron [3-pyridinecarboxamide, 2-((((4,6-dimethoxypyrimidin-2-yl) aminocarbonyl) aminosulfonyl))-N,N-dimethyl] in or on Bermudagrass, forage and Bermudagrass, hay at 10 ppm and 25 ppm respectively. EPA's assessment of exposures and risks associated with establishing time-limited tolerances follows.
A. 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 nicosulfuron used for human risk assessment can be found at http://www.regulations.gov in the July 14, 2009 document “Nicosulfuron: Human Health Risk Assessment for Proposed Section 18 Use on Bermudagrass,” pages 10 and 11 of 30 in docket ID number EPA-HQ-OPP-2009-0569.
B. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary exposure to nicosulfuron, EPA considered exposure under the time-limited tolerances established by this action as well as exposures pursuant to existing tolerances in (40 CFR 180.454). EPA assessed dietary exposures from nicosulfuron in food as follows:
i. Acute exposure. No acute effects were identified in the toxicological studies for nicosulfuron; therefore, a quantitative assessment of acute dietary exposure was not conducted.
ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used tolerance level residues and 100 percent crop treated (PCT) assumptions for all registered and proposed commodities.
iii. Cancer. EPA has classified nicosulfuron as “not likely to be carcinogenic to humans” based on the lack of tumorigenic effects in rodent (rat and mice) bioassays at the limit doses and lack of mutagenic effects in the in vitro and in vivo genotoxicity assays.
iv. Anticipated residue and PCT information. EPA did not use anticipated residue and/or PCT information in the dietary assessment for nicosulfuron. Tolerance level residues and/or 100 PCT were assumed for all registered and proposed food commodities.Start Printed Page 8259
2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for nicosulfuron in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of nicosulfuron. 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) for surface water and the Screening Concentration in Ground Water (SCI-GROW) model for ground water, the estimated drinking water concentrations (EDWCs) of nicosulfuron for chronic exposures for non-cancer assessments are estimated to be 0.7 parts per billion (ppb) for surface water and 0.06 ppb for ground water.
Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model.
For chronic dietary risk assessment, the water concentration of value 0.7 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).
Nicosulfuron is not registered for any specific use patterns that would result in residential exposure. Therefore, a residential risk assessment was not conducted.
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 nicosulfuron to share a common mechanism of toxicity with any other substances, and nicosulfuron does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that nicosulfuron 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 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.
C. 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 Food Quality Protection Act (FQPA) SF. In applying this provision, EPA either retains the default value of 10X, or uses a different additional SF 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 observed following in utero nicosulfuron exposure to rats or rabbits in the prenatal developmental studies or following prenatal/postnatal exposure in young rats in the 2-generation reproduction study. The toxicity database is considered adequate and includes acceptable developmental toxicity studies in the rat and rabbit and a rat reproductive study.
There were no developmental or reproductive effects observed in rats, but in rabbits (clinical signs, decreased body weight gain during dosing, increased abortions), postimplantation loss and decreased fetal body weight were observed at the maternal toxicity LOAEL. However, these effects were only observed at maternally toxic doses.
3. Conclusion. EPA has determined that reliable data show that 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 nicosulfuron is considered adequate for purposes of assessing human health risk from this emergency exemption use. Available data suggest that nicosulfuron is poorly absorbed and that toxicity is low. Further, data suggest increased pre and/or post natal susceptibility was not observed.
ii. The toxicity database for nicosulfuron is generally complete except for more recently required neurotoxicity and immunotoxicity testing requirements.
iii. There is no evidence of neurotoxicity or immunotoxicity in the available studies.
iv. There are no residual uncertainties with regard to assessing pre-and/or postnatal toxicity.
v. There are no residential use patterns for this chemical and the exposure assessments are conservative and will not underestimate risks.
D. 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. None of the toxicology studies available for nicosulfuron indentified an adverse effect resulting from a single-oral exposure; therefore, dietary exposure presents no acute risks of concern.
2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to nicosulfuron from food and water will utilize <1% of the cPAD for (children 3-5) the population subgroup receiving the greatest exposure. There are no residential uses for nicosulfuron. As explained in the unit regarding residential use patterns, chronic residential exposure to residues of nicosulfuron is not expected, so chronic risk is a function of dietary exposure alone. Thus, the chronic aggregate exposure for the most exposed group is below EPA's level of concern.
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).
Nicosulfuron is not registered for any use patterns that would result in residential exposure. Therefore, the short-term aggregate risk is the sum of Start Printed Page 8260the risk from exposure to nicosulfuron through food and water and will not be greater than the chronic aggregate risk.
4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account intermediate-term non-dietary, non-occupational exposure plus chronic exposure to food and water (considered to be a background exposure level).
Nicosulfuron is not registered for any use patterns that would result in intermediate-term residential exposure. Therefore, the intermediate-term aggregate risk is the sum of the risk from exposure to nicosulfuron through food and water, which has already been addressed, and will not be greater than the chronic aggregate risk.
5. Aggregate cancer risk for U.S. population.There is no cancer risk associated with the proposed use. Nicosulfuron is “not likely to be carcinogenic to humans” based on lack of tumorigenic effects in rodent (rats and mice) bioassays at the limit doses and lack of mutagenic effects in the in vitro and in vivo genotoxicity studies.
6. Determination of safety. Based on these risk assessments, EPA concludes that there is reasonable certainty that no harm will result to the general population, or to infants and children, from chronic aggregate exposure to nicosulfuron residues from food and drinking water.
V. Other Considerations
A. Analytical Enforcement Methodology
An adequate enforcement methodology (Ciba-Geigy, AG-499, and High Performance Liquid Chromatography/Ultraviolet (PLC/UV) method)) is available to enforce the time-limited tolerance expression. The method was recommended for inclusion in the Pesticide Analytical Manual Vol. II (PAM II).
B. International Residue Limits
There are currently no Canadian, Mexican, or Codex maximum residue limits (MRLs) for nicosulfuron on the commodities for which tolerances are being established.
Therefore, time-limited tolerances are established for residues of the herbicide nicosulfuron, [3-pyridineccarboxamide, 2-((((4,6-dimethoxypyrimidin-2-yl) aminocarbonyl)aminosulfonyl))-N,N-dimethyl], in or on Bermudagrass, forage and Bermudagrass, hay at 10 ppm and 25 ppm respectively. These tolerances expire and are revoked on December 31, 2011.
VII. Statutory and Executive Order Reviews
This final rule establishes tolerances under sections 408(e) and 408(l)(6) 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 in accordance with sections 408(e) and 408(l)(6) of FFDCA, such as the tolerances 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) (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).
VIII. 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
