II. Background and Statutory Findings

    In the Federal Register of June 1, 2005 (70 FR 31459) (FRL-7715-7), 
EPA issued a notice pursuant to section 408 of the Federal Food, Drug, 
and Cosmetic Act (FFDCA), 21 U.S.C. 346a, as amended by the Food 
Quality Protection Act (FQPA), announcing the filing of a pesticide 
petition (PP 5E6919) by the Monsanto Company. The petition requested 
that 40 CFR 180.471 be amended by the addition of tolerances for 
residues of furilazole (3-dichloroacetyl-5-(2-furanyl)-2, 2-
dimethyloxazolidine; (CAS Reg. No. 121776-33-8) on the sorghum 
commodities bran, flour, forage, grain, and stover at 0.01 parts per 
million (ppm). That notice included a summary of the petition prepared 
by the petitioner. No comments were received in response to the notice 
of filing.
    Section 408(b)(2)(A)(i) of the 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(c)(2)(A)(ii) of the 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 the 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. . . 
.'' These provisions were added to the FFDCA by the Food Quality 
Protection Act (FQPA) of 1996.

III. Risk Characterization and Conclusions

    Consistent with section 408(b)(2)(D) of the FFDCA, EPA has reviewed 
the available scientific data and other relevant information in support 
of this action and considered its validity, completeness and 
reliability and the relationship of this information 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. The nature of the toxic effects caused 
by furilazole is discussed in this unit. EPA has sufficient data to 
assess the hazards of and make a determination on aggregate exposure 
for the chemical. The following provides a brief summary of the risk 
assessment and conclusions for the Agency's review of furilazole. The 
full decision document for this action is available on EPA's Electronic 
Docket at https://www.regulations.gov/ under docket number EPA-HQ-OPP-
2007-0557.

A. Human Health

    The Agency reviewed the available information on furilazole 
submitted by the petitioner and determined that the toxicity database 
is sufficient. The toxicity studies used here were submitted for the 
establishment of tolerances of furilazole on corn commodities (Federal 
Register of April 3, 2002 (67 FR 15727) (FRL-6828-4). Laboratory 
studies in rodents show that exposure to furilazole may cause effects 
to the liver. In a 90-day oral toxicity study on rodents, the no 
observed effects level (NOAEL) was 7 milligrams/kilograms/day (mg/kg/
day) and the lowest observed effects level (LOAEL) was 34/38 mg/kg/day 
(male/female), and in a chronic toxicity study on the rat the NOAEL was 
0.26 mg/kg/day and the LOAEL was 5.05 mg/kg/day. Evidence of 
carcinogenicity was observed in rodents. For developmental toxicity, 
effects (increased number of re-sorptions; NOAEL was 10 mg/kg/day and 
the LOAEL was 75 mg/kg/day) were observed at maternally toxic doses. In 
the final rule, the Agency concluded ``no qualitative or quantitative 
evidence of increased susceptibility in the rat or rabbit fetuses 
following in-utero exposure in the developmental toxicity studies nor 
to the offspring following prenatal/postnatal exposure in the 2-
generation reproduction study.'' The Agency further concluded ``taking 
into account the lack of increased susceptibility and the completeness 
of the data on toxicity and exposure, EPA determined that the 10X 
safety factor to protect infants and children should be removed.'' 
There are no residual uncertainties regarding prenatal and/or postnatal 
toxicity.

B. Exposure Assessment

    The potential for exposure to residues of furilazole is adequately 
characterized based on the results of modeling and the crop residue 
studies. The results of the Dietary Exposure Evaluation Model (DEEM) 
model developed when tolerances for furilazole were first established 
on corn estimated that the amount of the dietary chronic population 
adjusted dose (cPAD) for the U.S. population was 1.4%, and the highest 
amount of the cPAD was 3.4% for all infants less than 1 year old. 
Estimates for potential cancer risks were also very low.
    Residue studies (crop field trials and processed) show that 
residues of furilazole on sorghum commodities were non-quantifiable 
(less than the Limit of Quantitation (LOQ) of 0.010 ppm) in all samples 
of sorghum forage, grain, and stover.
    Considering the results of the residue studies for furilazole on 
sorghum commodities and exposure modeling, the Agency concludes that 
dietary (food and drinking water) exposures of concern are not 
anticipated from the inert ingredient use of furilazole on the sorghum 
commodities forage, grain, and stover. Residential exposure is not 
expected because applications are limited to the agricultural crop 
sorghum. EPA is not aware of non-pesticide uses of furilazole, 
therefore, no further aggregate assessment is necessary.

C. Safety Factor for Infants and Children

    Section 408 of the FFDCA provides that EPA shall apply an 
additional tenfold margin of safety for infants and children in the 
case of threshold effects to account for prenatal and postnatal 
toxicity and the completeness of the database on toxicity and exposure 
unless EPA determines that a different margin of safety will be safe 
for infants and children. Margins of safety are incorporated into EPA 
risk assessments either directly through use of a margin of exposure 
analysis or through using uncertainty (safety) factors in calculating a 
dose level that poses no appreciable risk to humans. The toxicity 
database is sufficient for furilazole and

[[Page 57491]]

potential exposure is adequately characterized based on results of the 
residue studies for furilazole on sorghum commodities and exposure 
modeling. In terms of hazard, there are low concerns and no residual 
uncertainties regarding prenatal and/or postnatal toxicity. Taking into 
account the lack of increased susceptibility and the completeness of 
the data on toxicity and exposure, EPA determined that the 10X safety 
factor to protect infants and children should be removed.

D. Cumulative Exposure

    Section 408(b)(2)(D)(v) of the FFDCA requires that, when 
considering whether to establish, modify, or revoke a tolerance, the 
Agency consider ``available information'' concerning the cumulative 
effects of a particular pesticide's residues and ``other substances 
that have a common mechanism of toxicity.'' Unlike other pesticides for 
which EPA has followed a cumulative risk approach based on a common 
mechanism of toxicity, EPA has not made a common mechanism of toxicity 
finding as to furilazole and any other substances, and the chemical 
does not appear to produce a toxic metabolite produced by other 
substances. For the purposes of this tolerance action, therefore, EPA 
has not assumed that furilazole has a common mechanism of toxicity with 
other substances. For information regarding EPA's efforts to determine 
which chemicals have a common mechanism of toxicity and to evaluate the 
cumulative effects of such chemicals, see EPA's website at https://
www.epa.gov/pesticides/cumulative.

E. Other Considerations

    1. Analytical methods. Adequate enforcement methodology (capillary 
gas chromotography using electron capture detection) is available to 
enforce the tolerance exemption 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.
    2. International tolerances. The Agency is not aware of any country 
requiring a tolerance for furilazole nor have any CODEX Maximum Residue 
Levels (MRLs) been established for any food crops at this time.

F. Determination of Safety and Conclusions

    The petitioner requested tolerances for sorghum flour and bran, 
nevertheless, these tolerances are not being established. The Agency 
has determined that tolerances for these processed commodities are not 
necessary because the residue data showed that residues of furilazole 
were non-quantifiable (less than 0.010 ppm) in all samples of grain 
(RAC) and processed fractions.
    Laboratory studies in show that exposure to furilazole may cause 
effects to the liver and evidence of carcinogenicity was observed. 
Developmental effects were observed at maternally toxic doses and there 
was no qualitative or quantitative evidence of increased susceptibility 
in the rat or rabbit fetuses. Therefore, the 10X safety factor to 
protect infants and children is removed.
    The results of the DEEM model that was developed when tolerances 
for furilazole were first established estimated the amount of the 
dietary cPAD for the U.S. population was 1.4%, and the highest amount 
of the cPAD was 3.4% for all infants less than 1 year old. Estimates 
for potential cancer risks were also very low. Residue studies (crop 
field trials and processed) on sorghum commodities show that residues 
of furilazole were non-quantifiable (less than the LOQ of 0.010 ppm). 
Considering the results of the residue studies and the conservative 
exposure modeling, the Agency concludes that dietary (food and drinking 
water) exposures of concern are not anticipated from the inert 
ingredient use of furilazole on sorghum commodities. Residential 
exposure is not expected because applications are limited to the 
agricultural crop sorghum. The Agency is not aware of any non-pesticide 
uses of furilazole, therefore, no further exposure assessment is 
necessary.
    Based on the information in this preamble, EPA concludes that there 
is a reasonable certainty of no harm to the general population, 
including infants and children, from aggregate exposure to residues of 
furilazole. Accordingly, EPA finds that establishing tolerances for 
furilazole will be safe. EPA is establishing tolerances under 40 CFR 
180.471 for residues of furilazole in or on the sorghum commodities 
forage, grain, and stover at 0.01 ppm when it is used as an inert 
ingredient safener.
    In addition, the annual application rate limitation found in 40 CFR 
180.471 is being removed because it is unnecessary. The establishment 
of tolerance levels provides adequate regulation under FFDCA.

IV. 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 rule has been 
exempted from review under Executive Order 12866, this rule is not 
subject to Executive Order 13211, Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, 
May 22, 2001) 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 6, 
2000) do not apply to this rule. In addition, This 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

[[Page 57492]]

Transfer and Advancement Act of 1995 (NTTAA), Public Law 104-113, 
section 12(d) (15 U.S.C. 272 note).

V. 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).
