II. Petition for Tolerance

    In the Federal Register of June 13, 2008 (73 FR 33817) (FRL-8367-
3), 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 
7F7307) by E.I. DuPont de Nemours and Company, DuPont Crop Protection, 
Laurel Run Plaza, P. O. Box 80038, Wilmington, DE 19880-0038. The 
petition requested that 40 CFR 180.364 be amended by establishing 
tolerances for combined residues of the herbicide, glyphosate, N-
(phosphonomethyl)glycine and its metabolite N-acetylglyphosate (N-
acetyl-N-(phosphonomthyl)glycine) resulting from the application of 
glyphosate, the isopropylamine salt of glyphosate, the ethanolamine 
salt of glyphosate, the ammonium salt of glyphosate, and the potassium 
salt of glyphosate to Optimum\TM\ GAT\TM\ field corn, in or on the food 
commodities field, corn, grain; field, corn, forage, aspirated grain 
fractions at levels already established alone. That notice referenced a 
summary of the petition prepared by E.I. DuPont de Nemours and Company. 
the registrant, which is available to the public in the docket, http://www.regulations.gov. Comments were received on the notice of filing. 
EPA's response to these comments is discussed in Unit IV.C. DuPont has 
requested a Section 3 registration under Federal Insecticide, 
Fungicide, and Rodenticide Act (FIFRA) for the preplant application of 
the herbicides glyphosate and pyrithiobac sodium to glyphosate tolerant 
field corn. The petitioner is also working to commercialize a 
genetically modified field corn designated as Optimum\TM\ GAT\TM\ corn. 
N-acetyl glyphosate is produced when glyphosate is applied to Optimum 
GAT corn. As a result the petitioner is requesting that the currently 
established tolerances on field corn commodities be modified 
accordingly.
    Based upon review of the data supporting the petition, EPA has 
reassigned the currently established tolerances for corn, field, grain 
at 5.0 parts per million (ppm) and corn, field, forage at 6.0 ppm in 
paragraph 40 CFR 180.364 (a)(1) to paragraph 40 CFR 180.364 (a)(2). The 
tolerance expression for paragraph (a)(2) reads ``Tolerances are 
established for the combined residues of glyphosate, N-
(phosophonomethyl)glycine and its metabolite N-acetyl-glyphosate 
(expressed as glyphosate) resulting from the application of glyphosate, 
the isopropylamine salt of glyphosate, the ethanolamine salt of 
glyphosate, the dimethylamine salt of glyphosate, the ammonium salt of 
glyphosate, and the potassium salt of glyphosate on the food 
commodities:''. The Agency is also establishing a tolerance for corn, 
field, stover at 100 ppm and assigning it to paragraph (a)(2). The 
Agency is also changing the current commodity definition for the 
currently established grain, cereal, forage, fodder and straw, group 
16, except field corn, forage in paragraph (a)(1) to read: Grain, 
cereal, forage, fodder, and straw, group 16, except field corn, forage 
and field corn, stover. The currently established tolerance for grain, 
aspirated fractions at 310 ppm in paragraph (a)(2) will remain 
unchanged. The reasons for these changes are explained in Unit IV.D.

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 combined residues of glyphosate, N-
(phosophonomethyl)glycine and its metabolite N-acetyl-glyphosate 
(expressed as glyphosate) resulting from the application of glyphosate, 
the isopropylamine salt of glyphosate, the ethanolamine salt of 
glyphosate, the dimethylamine salt of glyphosate, the ammonium salt of 
glyphosate, and the potassium salt of glyphosate on the food 
commodities: corn, field, forage at 6.0 ppm; corn, field, grain at 5.0 
ppm; corn, field , stover at 100 ppm; and for the combined residues 
glyphosate, phosophonomethyl)glycine resulting from the application of 
glyphosate, the isopropylamine salt of glyphosate, the ethanolamine 
salt of glyphosate, the dimethylamine salt of glyphosate, the ammonium 
salt of glyphosate, and the potassium salt of glyphosate on the food 
commodity grain, cereal, forage, fodder, and straw, group 16, except 
field corn, forage and field corn, stover at 100 ppm. EPA's assessment 
of exposures and risks associated with establishing tolerances follows.

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. Specific information on the studies received and the nature 
of the adverse effects caused by glyphosate per se and glyphosate and 
its metabolite N-acetyl-glyphosate as well as no-observed-effect-level 
(NOEL) and the lowest-observed-adverse-effect-level (LOAEL) from the 
toxicity studies can be found in the documents in this unit.
    The toxicological profile of glyphosate per se can be found in the 
risk

[[Page 67131]]

assessments referenced in the final rule published in the Federal 
Register of December 3, 2008 (73 FR 73586) (FRL-8385-7) which 
establishes tolerances for glyphosate and its metabolite N-acetyl-
glyphosate in or on cattle, meat byproducts and various other 
commodities and in the risk assessment referred to in the final rule 
published in the Federal Register of December 20, 2006 (71 FR 76180) 
(FRL-8105-9) which established tolerances for residues of glyphosate in 
or on noni at 0.20 ppm and various other commodities. The toxicological 
profile for the metabolite N-acetyl-glyphosate and N-acetyl 
amionomethylphosphonic acid (N-acetyl-AMPA), one of the metabolites 
formed following oral administration of N-acetyl-glyphosate can be 
found in the same rule making documents.
    Amendment of the glyphosate corn tolerances to include N-acetyl-
glyphosate in the tolerance expression does not result in changes in 
the exposure or risk estimates reported in the previous risk 
assessments for the reasons listed in this unit and discussed in the 
Agency review entitled Glyphosate and Pyrithiobac Sodium. Amended 
Section 3 Registration to Permit the Rotation to Glyphosate-Tolerant 
Field Corn and Glyphosate-Tolerant Soybean following Application to 
Glyphosate-Tolerant Cotton and Revison of the Field Corn Tolerance 
Expression. Summary of Analytical Chemistry and Residue Data., 
available at www.regulations.gov in Docket ID number EPA-HQ-OPP-2008-
0385 and identified as document EPA-HQ-OPP-2008-0385-005.
    1. The Agency has determined that N-acetyl-glyphosate has no 
greater toxicity than glyphosate and probably is of lower toxicity.
    2. The numerical value of the currently-established tolerances for 
field corn commodities, livestock and poultry commodities, and feed 
commodities will remain unchanged.
    3. The most recent dietary analysis assumed tolerance level 
residues and 100 percent crop treated.
    4. The estimate of glyphosate in drinking water is based on a 
glyphosate use involving direct application to water at 3.75 pounds 
active ingredient per acre. Use of glyphosate on glyphosate-resistant 
corn will not result in higher levels in drinking water.
    Accordingly, based on the risk assessments and findings discussed 
in the notices referenced in this unit, EPA concludes that no harm will 
result to the general population and to infants and children from 
aggregate exposure to the combined residues of glyphosate and its 
metabolite N-acetyl-glyphosate (expressed as glyphosate).

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (high performance liquid 
chromatography (HPLC) with tandem mass spectrometery (MS/MS)) 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 Codex Maximum Residue Levels (MRLS) established for 
glyphosate (sum of glyphosate and AMPA) on maize at 5 mg/kg and maize 
fodder (dry ) at 150 mg/kg. A Canadian MRL is established for 
glyphosate including the metabolite aminomethylphosphonic acid (AMPA) 
on corn at 3 mg/kg. A Mexican MRL is established for corn at 0.1 mg/kg 
for glyphosate. The glyphosate tolerances EPA is establishing in this 
action differ from the tolerance expression for the CODEX, Canadian, or 
Mexican MRLs, because of the inclusion of N-acetyl-glyphosate in the 
expression. Additionally, the EPA tolerances differ from the CODEX or 
Canadian MRLs in that the EPA tolerances do not include AMPA in the 
tolerance expression. At this time, harmonization between the U.S. 
tolerances and the CODEX, Canadian, or Mexican MRLs can not be achieved 
because the inclusion of N-acetyl-glyphosate in the EPA tolerance 
expression is necessary to support use patterns in the United States 
and because EPA has concluded that AMPA it not toxicologically 
significant and therefore, should not be included in the tolerance 
expression.

C. Response to Comments

    One commenter submitted two comments opposing the use of glyphosate 
and glyphosate resistant plants which have resulted in the increased 
use of glyphosate. The commenter also questions the effect of 
glyphosate on bee colonies. A similar comment concerning effect on bees 
was received previously and addressed in the notice published in the 
Federal Register on December 3, 2008. EPA does not regulate the effect 
of herbicide resistant plants on the environment. That function is 
handled by the United States Department of Agriculture (USDA) Animal 
and Plant Inspection Service (APHIS). The effect of herbicide resistant 
plants on the environment is not relevant to EPAs determination of 
safety of the pesticide glyphosate under section 408 of the FFDCA. The 
Agency's database on the chemical glyphosate indicates that no harm 
will result to the general population and to infants and children from 
aggregate exposure to glyphosate per se or from glyphosate and its 
metabolite N-acetyl-glyphosate as discussed in the final rules and risk 
assessments referenced in this document. The commenter did not submit 
any information to support a revision of Agency conclusions.

D. Revisions to Petitioned-For Tolerances

    Because the tolerance expression for field corn changes as a result 
of the inclusion of the metabolite N-acetyl-glyphosate into the 
expression, the Agency is deleting the currently established tolerances 
for corn, field, grain (5.0 ppm) and corn, field forage (6.0 ppm) from 
40 CFR 180.364 (a)(1) and reestablishing them in 40 CFR 180.364(a)(2) 
and establishing a tolerance for corn, field, stover at 100 ppm and 
assigning it to paragraph (a)(2). Because a separate tolerance for 
corn, field, stover is being established under paragraph (a)(2), the 
commodity definition for the currently-established grain, cereal, 
forage, fodder, and straw, group 16, except field corn, forage in 
paragraph (a)(1) is being changed to read grain, cereal, forage, fodder 
and straw, group 16, except field corn, forage and field corn, stover. 
As discussed in the final rule published in the Federal Register of 
December 3, 2008, this change to the tolerance expression for 
glyphosate as it applies to these field corn commodities will not have 
any impact on these field corn tolerances in terms of how they apply to 
glyphosate applied to non-genetically modified field corn.

V. Conclusion

    Therefore, tolerances are established for combined residues of 
glyphosate, N-(phosophonomethyl)glycine and its metabolite N-acetyl-
glyphosate (expressed as glyphosate) resulting from the application of 
glyphosate, the isopropylamine salt of glyphosate, the ethanolamine 
salt of glyphosate, the dimethylamine salt of glyphosate, the ammonium 
salt of glyphosate, and the potassium salt of glyphosate on the food 
commodities: Corn, field, forage at 6.0 ppm; corn, field, grain at 5.0 
ppm; corn, field , stover at 100 ppm; and for the combined residues 
glyphosate, phosophonomethyl)glycine resulting from the application of 
glyphosate, the

[[Page 67132]]

isopropylamine salt of glyphosate, the ethanolamine salt of glyphosate, 
the dimethylamine salt of glyphosate, the ammonium salt of glyphosate, 
and the potassium salt of glyphosate on the food commodity grain, 
cereal, forage, fodder, and straw, group 16, except field corn, forage 
and field corn, stover at 100 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, 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 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).

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).
