II. Petition for Tolerance

    In the Federal Register of September 28, 2007 (72 FR 55204) (FRL-
8147-1), 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 
7F7243) by Valent U.S.A. Corporation, 1600 Riviera Avenue, Suite 200, 
Walnut Creek, CA 94596. The petition requested that 40 CFR 180.568 be 
amended by establishing tolerances for residues of the herbicide 
flumioxazin, 2-[7-fluoro-3,4-dihydro-3-oxo-4-(2-propynyl)-2H-1,4-
benzoxazin-6-yl]-4,5,6,7-tetrahydro-1H-isoindole-1,3(2H)-dione, in or 
on corn, field grain; corn, field forage; and corn, field stover at 
0.02 parts per million (ppm). That notice referenced a summary of the 
petition prepared by Valent U.S.A. Corporation, the registrant, which 
is available to the public in the docket, http://www.regulations.gov. 
There were no comments received in response to the notice of filing.

III. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a 
tolerance (the legal limit for a pesticide chemical residue in or on a 
food) only if EPA determines that the tolerance is ``safe.'' Section 
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the pesticide chemical residue, including all anticipated dietary 
exposures and all other exposures for which there is reliable 
information.'' This includes exposure through drinking water and in 
residential settings, but does not include occupational exposure. 
Section 408(b)(2)(C) of FFDCA requires EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance and to ``ensure that there 
is a reasonable certainty that no harm will result to infants and 
children from aggregate exposure to the pesticide chemical 
residue....''
    Consistent with section 408(b)(2)(D) of FFDCA, and the factors 
specified in section 408(b)(2)(D) of FFDCA, EPA has reviewed the 
available scientific data and other relevant information in support of 
this action. EPA has sufficient data to assess the hazards of and to 
make a determination on aggregate exposure for the petitioned-for 
tolerances for residues of flumioxazin on corn, field grain; corn, 
field forage; and corn, field stover at 0.02 ppm. EPA's assessment of 
exposures and risks associated with establishing 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.
    Flumioxazin has mild or no acute toxicity when administered orally, 
dermally, or by inhalation. It has little or no toxicity with regard to 
eye irritation or skin irritation and is not a dermal sensitizer. 
Subchronic and chronic toxicity studies demonstrated that the target 
organs of flumioxazin are the liver, spleen and cardiovascular system. 
Developmental effects were observed in developmental rat studies. These 
effects were fetal cardiovascular anomalies (especially ventricular 
septal defects). Flumioxazin has been classified as a ``Not Likely 
Human Carcinogen,'' based on the lack of carcinogenicity in a 2-year 
rat study, an 18-month mouse study, and a battery of mutagenic studies.
    Specific information on the studies received and the nature of the 
adverse effects caused by flumioxazin as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at http://
www.regulations.gov in document ``Flumioxazin; Human Health Risk 
Assessment for the Proposed Food Use on Field Corn,'' at page 39 in 
docket ID number EPA-HQ-OPP-2007-0871.

B. 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 NOAEL in the toxicology study 
identified as appropriate for use in risk assessment. However, if a 
NOAEL cannot be determined, 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-
term, intermediate-term, 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 flumioxazin used for 
human risk assessment can be found at http://www.regulations.gov in 
document ``Flumioxazin; Human Health Risk Assessment for the Proposed 
Food Use on Field Corn,'' at page 23 in docket ID number EPA-HQ-OPP-
2007-0871.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to flumioxazin, EPA considered exposure under the petitioned-
for tolerances as well as all existing flumioxazin tolerances in (40 
CFR 180.568). EPA assessed dietary exposures from flumioxazin in food 
as follows:
    i. Acute exposure. Quantitative acute dietary exposure and risk 
assessments are performed for a food-use pesticide, if a toxicological 
study has indicated the possibility of an effect of concern occurring 
as a result of a 1-day or single exposure. No such effect was 
identified for the general population. However, EPA identified 
potential acute effects, e.g., cardiovascular effects in offspring, for 
the population subgroup, females 13

[[Page 39249]]

to 49 years. In estimating acute dietary exposure, EPA used food 
consumption information from the U.S. Department of Agriculture (USDA) 
1994-1996 Nationwide Continuing Surveys of Food Intake by Individuals 
(CSFII). As to residue levels in food, EPA assumed all foods for which 
there are tolerances (current and proposed) were treated (100% crop 
treated assumption) and contain tolerance-level residues. Percent crop 
treated (PCT) and/or anticipated residues were not used in the acute 
risk assessment.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the USDA 1994-1996 
CSFII. As to residue levels in food, EPA assumed all foods for which 
there are tolerances (current and proposed) were treated (100 PCT 
assumption) and contain tolerance-level residues. Percent crop treated 
(PCT) and/or anticipated residues were not used in the risk assessment.
    iii. Cancer. The Agency has determined that flumioxazin is ``not 
likely to be a human carcinogen'' based on the lack of carcinogenicity 
in a 2-rat study, an 18 month mouse study, and a battery of mutagenic 
studies. Therefore, a quantitative exposure assessment to evaluate 
cancer risk is unnecessary.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for flumioxazin and its degradates, 482-HA and APF, in 
drinking water. These simulation models take into account data on the 
physical, chemical, and fate/transport characteristics of flumioxazin 
and its degradates. Further information regarding EPA drinking water 
models used in pesticide exposure assessment can be found at http://
www.epa.gov/oppefed1/models/water/index.htm.
    Based on the First Index Reservoir Screening Tool (FIRST), and 
Screening Concentration in Ground Water (SCI-GROW) models, the 
estimated drinking water concentrations (EDWCs) of flumioxazin for 
acute exposures are estimated to be 34 parts per billion (ppb) for 
surface water and 48 ppb for ground water.
    The EDWCs for chronic exposures for non-cancer assessments are 
estimated to be 18 ppb for surface water and 48 ppb for ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For acute dietary risk 
assessment, the water concentration value of 48 ppb was used to assess 
the contribution to drinking water. For chronic dietary risk 
assessment, the water concentration of value 48 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).
    Flumioxazin is not registered for any specific use patterns that 
would result in residential exposure.
    4. Cumulative effects from substances with a common mechanism of 
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when 
considering whether to establish, modify, or revoke a tolerance, the 
Agency consider ``available information'' concerning the cumulative 
effects of a particular pesticide's residues and ``other substances 
that have a common mechanism of toxicity.''
    EPA has not found flumioxazin to share a common mechanism of 
toxicity with any other substances, and flumioxazin does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
flumioxazin does not have a common mechanism of toxicity with other 
substances. For information regarding EPA's efforts to determine which 
chemicals have a common mechanism of toxicity and to evaluate the 
cumulative effects of such chemicals, see EPA's website at http://
www.epa.gov/pesticides/cumulative.

D. Safety Factor for Infants and Children

    1. In general. Section 408(b)(2)(c) of FFDCA provides that EPA 
shall apply an additional tenfold (10X) margin of safety for infants 
and children in the case of threshold effects to account for prenatal 
and postnatal toxicity and the completeness of the database on toxicity 
and exposure unless EPA determines based on reliable data that a 
different margin of safety will be safe for infants and children. This 
additional margin of safety is commonly referred to as the FQPA safety 
factor (SF). In applying this provision, EPA either retains the default 
value of 10X, or uses a different additional safety factor when 
reliable data available to EPA support the choice of a different 
factor.
    2. Prenatal and postnatal sensitivity. The pre-natal and post-natal 
toxicity database for flumioxazin includes the rat and rabbit 
developmental toxicity studies and the 2-generation reproduction 
toxicity study in rats. There is evidence of quantitative 
susceptibility following oral and dermal exposures to rats. Following 
in utero exposures, developmental effects (cardiovascular anomalies) 
were seen in the absence of maternal toxicity. There is no evidence 
(quantitative or qualitative) of susceptibility following in utero oral 
exposure in rabbits. No developmental toxicity was seen at the highest 
dose tested (3x the Limit-Dose). There is quantitative evidence of 
susceptibility in the multi-generation reproduction study where effects 
in offspring were seen at doses lower than those which induced effects 
in parental animals.
    Although increased pre-natal and post-natal quantitative 
susceptibility was seen in rats, the Agency concluded that there is a 
low concern and no residual uncertainties for pre-natal and/or post-
natal toxicity effects of flumioxazin because:
    i. Developmental toxicity (including cardiovascular abnormalities) 
NOAELs and LOAELs from pre-natal exposure are well characterized after 
oral and dermal exposure,
    ii. The off-spring toxicity NOAEL and LOAEL from post-natal 
exposure are well characterized,
    iii. The dose selected for risk assessment is protective of all 
potential effects.
    3. Conclusion. EPA has determined that reliable data show the 
safety of infants and children would be adequately protected if the 
FQPA SF were reduced to 1X. That decision is based on the following 
findings:
    i. The toxicity database for flumioxazin is complete.
    ii. There is no indication that flumioxazin is a neurotoxic 
chemical and there is no need for a developmental neurotoxicity study 
or additional UFs to account for neurotoxicity.
    iii. Although there is quantitative evidence of increased 
susceptibility in the pre-natal developmental studies and post-natal 
multi-generation study in rats, EPA did not identify any residual 
uncertainties after establishing toxicity endpoints and traditional UFs 
to be used in the risk assessment of flumioxazin. The degree of concern 
for pre-natal and/or post-natal toxicity is low.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100 PCT and tolerance-level residues for all commodities. EPA made 
conservative (protective) assumptions in the ground water and surface 
water modeling used to assess exposure to flumioxazin in drinking 
water. EPA used similarly conservative assumptions to assess post 
application exposure of children as well

[[Page 39250]]

as incidental oral exposure of toddlers. These assessments will not 
underestimate the exposure and risks posed by flumioxazin.

E. 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-term, intermediate-term, 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. Using the exposure assumptions discussed in this 
unit for acute exposure, the acute dietary exposure from food and water 
to flumioxazin will occupy 8% of the aPAD for (females 13 to 49) the 
population group receiving the greatest exposure.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
flumioxazin from food and water will utilize 19% of the cPAD for 
(Infants less than 1 year old) the population group receiving the 
greatest exposure. There are no residential uses for flumioxazin.
    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).
    Flumioxazin is not registered for any use patterns that would 
result in residential exposure. Therefore, the short-term aggregate 
risk is the sum of the risk from exposure to flumioxazin 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 residential exposure plus chronic 
exposure to food and water (considered to be a background exposure 
level).
    Flumioxazin 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 flumioxazin through food and water, which has already been 
addressed, and will not be greater than the chronic aggregate risk.
    5. Determination of safety. Based on these risk assessments, EPA 
concludes that there is a reasonable certainty that no harm will result 
to the general population, or to infants and children from aggregate 
exposure to flumioxazin residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (gas chromatography/nitrogen- 
phosphorus detection) is available to enforce the tolerance expression. 
The method may be requested from: Chief, Analytical Chemistry Branch, 
Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; 
telephone number: (410) 305-2905; e-mail address: 
residuemethods@epa.gov.

B. International Residue Limits

    There are no established or proposed Canadian, Mexican or Codex 
maximum residue levels (MRLs) for residues of flumioxazin in plant 
commodities subject to this action.

V. Conclusion

    Therefore, tolerances are established for residues of flumioxazin, 
2-[7-fluoro-3,4-dihydro-3-oxo-4-(2-propynyl)-2H-1,4-benzoxazin-6-yl]-
4,5,6,7-tetrahydro-1H-isoindole-1,3(2H)-dione, in or on corn, field 
grain; corn, field forage; and corn, field stover at 0.02 ppm.

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances under section 408(d) of 
FFDCA in response to a petition submitted to the Agency. The Office of 
Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled Regulatory Planning and 
Review (58 FR 51735, October 4, 1993). Because this final rule has been 
exempted from review under Executive Order 12866, this final rule is 
not subject to Executive Order 13211, Actions Concerning Regulations 
That Significantly Affect Energy Supply, Distribution, or Use (66 FR 
28355, May 22, 2001) or Executive Order 13045, entitled Protection of 
Children from Environmental Health Risks and Safety Risks (62 FR 19885, 
April 23, 1997). This final rule does not contain any information 
collections subject to OMB approval under the Paperwork Reduction Act 
(PRA), 44 U.S.C. 3501 et seq., nor does it require any special 
considerations under Executive Order 12898, entitled Federal Actions to 
Address Environmental Justice in Minority Populations and Low-Income 
Populations (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis 
of a petition under section 408(d) of FFDCA, such as the tolerance in 
this final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.) do not apply.
    This final rule directly regulates growers, food processors, food 
handlers, and food retailers, not States or tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by 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).

[[Page 39251]]

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).
