Nicosulfuron; Pesticide Tolerances for Emergency Exemptions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation establishes 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. This action is in 
response to EPA granting crisis exemptions to the Texas Department of 
Agriculture and the Oklahoma Department of Agriculture under section 18 
of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) 
authorizing use of the pesticide on Bermudagrass, forage and 
Bermudagrass, hay. This regulation establishes maximum permissible 
levels for residues of nicosulfuron in Bermudagrass and hay. The time-
limited tolerances expire and are revoked on December 31, 2011.

DATES: This regulation is effective February 24, 2010. Objections and

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

[[Page 8258]]

considered 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.

[[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 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.

VI. Conclusion

    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).
