II. Petition for Tolerance

    In the Federal Register of February 28, 2007 (72 FR 9000) (FRL-
8115-5), 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 
6F7161) by Bayer CropScience LLC, 2 T.W. Alexander Dr.,

[[Page 72623]]

Research Triangle Park, NC 27709. The petition requested that 40 CFR 
180.473 be amended by establishing a tolerance for combined residues of 
the herbicide, glufosinate-ammonium and its metabolites expressed as 
butanoic acid, 2-amino-4-(hydroxymethylphosphinyl)-, monoammonium salt, 
2-acetamido-4-methylphosphinico-butanoic acid and 3-methylphosphinico-
propionic acid (expressed as glufosinate free acid equivalents), in or 
on raw agricultural commodities grain aspirated fractions at 25.0 parts 
per million (ppm); non- transgenic canola, meal at 1.1 ppm; non-
transgenic canola, seed at 0.4 ppm; non- transgenic field corn, forage 
at 4.0 ppm; non- transgenic field corn, grain at 0.2 ppm; non- 
transgenic field corn, stover at 6.0 ppm; non- transgenic soybean, at 
2.0 ppm; non-transgenic soybean, hulls at 5.0 ppm. That notice 
referenced a summary of the petition prepared by Bayer CropScience LLC, 
the registrant, which is available to the public in the docket, http://www.regulations.gov
.

     In the Federal Register of June 27, 2007 (72 FR 35237) (FRL-8133-
4), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 
U.S.C. 346a(d)(3), announcing the amendment to existing tolerances by 
filing of a pesticide petition (PP 6F7161) by Bayer CropScience LLC, 2 
T.W. Alexander Dr., Research Triangle Park, NC 27709. The petition 
proposes to amend the tolerances in 40 CFR 180.473(a) to eliminate the 
reference to transgenic crops tolerant to glufosinate ammonium in 
Sec. 180.473(a)(2) such that the crop tolerances listed under 
Sec. 180.473 (a) General, support uses in all of the crops listed to 
include both conventional and transgenic crops and to delete 
Sec. 180.473 (a)(1) and (a)(2). This notice clarifies the initial 
notice of filing published in the Federal Register of February 28, 2007 
(72 FR 9000) (FRL-8115-5). The tolerances for glufosinate-ammonium and 
its metabolites listed for the commodities under both paragraphs (a)(1) 
and paragraph (a)(2) are proposed to be placed in Sec. 180.473 (a) 
General to read as follows: Tolerances are established for residues of 
glufosinate-ammonium (butanoic acid, 2-amino-4-
(hydroxymethylphosphinyl)-monoammonium salt) and its metabolites 
expressed as butanoic acid, 2-amino-4-(hydroxymethylphosphinyl)-, 
monoammonium salt, 2-acetamido-4-methylphosphinico-butanoic acid and 3-
methylphosphinico-propionic acid expressed as glufosinate free acid 
equivalents in or on the raw agricultural commodities: Almond, hulls at 
0.50 ppm; apple at 0.05 ppm; grain aspirated fractions at 25.0 ppm; 
banana at 0.30 ppm; banana, pulp at 0.20 ppm; beet, sugar, molasses at 
5.0 ppm; beet, sugar, roots at 0.9 ppm; beet, sugar, tops at 1.5 ppm;

at 0.40 ppm; sheep, meat at 0.15 ppm; sheep, meat byproducts at 6.0 
ppm; soybean at 2.0 ppm and soybean, hulls at 5.0 ppm.
    Comments were received on the notices of filing. EPA's response to 
these comments is discussed in Unit IV.C.
    Bayer's petition asks EPA to consolidate subsections (a)(1) and 
(a)(2) of 40 CFR 180.473 which contains tolerances for glufosinate on 
various non-transgenic crops and transgenic crops, respectively, and 
remove the restriction as to transgenic crops. In part this petition is 
related to Bayer's application to EPA to amend its glufosinate 
registration under the Federal Insecticide, Fungicide, and Rodenticide 
Act (FIFRA) to allow pre-plant burn down application to both transgenic 
and non-transgenic field corn, canola, and soybean. Glufosinate is 
currently registered foliar uses on the transgenic forms of these 
crops. The proposed registration amendment would not alter existing 
seasonal application amount limitations. There are currently no FFDCA 
tolerances for glufosinate on non-transgenic field corn, canola, and 
soybean but FFDCA tolerances are in place for the foliar use on the 
transgenic form of these crops. Consolidating subsections (a)(1) and 
(a)(2) and removing the transgenic restriction would address the lack 
of tolerances for non-transgenic field corn, canola, and soybean.
    EPA initially concluded that two tolerance expressions were 
appropriate for plants: non-transgenic (40 CFR 180.473 (a)(1)) with 
glufosinate ammonium and 3-methylphosphinico-propionic acid and 
transgenic crops (40 CFR 180.473 (a)(2)) with glufosinate ammonium, N-
acetyl-glufosinate, and 3-methylphosphinico-propionic acid. Subsequent 
to this decision, based upon a petition from Bayer, EPA modified the 
tolerance expressions in subsections (a)(1) and (a)(2) so that they are 
identical for transgenic and non-transgenic crops. 68 FR 55833 
(September 29, 2003). This modification was done because EPA concluded 
that a single tolerance expression for both transgenic crops and non-
transgenic crops (i.e. glufosinate ammonium, N-acetyl-glufosinate, and 
3-methylphosphinico-propionic acid) was appropriate for the following 
reasons: 1) Enforcement laboratories do not know if a sample is derived 
from transgenic or non-transgenic crop and 2) the enforcement method 
quantifies glufosinate ammonium and N-acetyl-glufosinate together (both 
are devitalized to the same compound). As a result of the decision, the 
tolerance expression for 40 CFR 180.473 (a)(1) was altered to include 
N-acetyl-glufosinate; however, the tolerances in 40 CFR 180.473 (a)(2) 
remains. EPA has determined that consolidating the existing glufosinate 
tolerances in subsections (a)(1) and (a)(2) and removing the transgenic 
crop restriction, where applicable, is safe and is appropriate. 
Tolerance levels will not need to be increased with the addition of a 
pre-plant burn down use because the same seasonal amount limitations 
are being retained. Given that foliar applications would result in 
higher residue levels than pre-plant burn down, allocation of a portion 
of the permitted application to the pre-plant burn down use will not 
increase the residue level that could be present.

III. Aggregate Risk Assessment and Determination of Safty

    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

[[Page 72624]]

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 
FFDCA by the Food Quality Protection Act (FQPA) of 1996.
    Consistent with FFDCA section 408(b)(2)(D), and the factors 
specified in FFDCA section 408(b)(2)(D), 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 proposal to 
place all the commodities listed in 180.473 (a)(1) and 180.473 (a)(2) 
together in paragraph 180.473(a) based on the rationale for having a 
single tolerance expression is appropriate. Tolerance levels for 
combined residues of glufosinate-ammonium are unchanged. EPA's 
assessment of exposures and risks associated with establishing the 
tolerance 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. Specific information on the studies received and the nature 
of the adverse effects caused by glufosinate-ammonium as well as the 
no-observed-adverse-effect-level (NOAEL) and the lowest-observed-
adverse-effect-level (LOAEL) from the toxicity studies.
    Specific information on the studies received and the nature of the 
toxic effects caused by glufosinate ammonium as well as the no-
observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-
effect-level (LOAEL) from the toxicity studies are discussed in the 
final rule published in the Federal Register of September 29, 2003 (68 
FR 55833) (FRL-7327-9).

B. Toxicological Endpoints

    For hazards that have a threshold below which there is no 
appreciable risk, the toxicological level of concern (LOC) is derived 
from 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) is 
sometimes used for risk assessment. Uncertainty/safety factors (UFs) 
are used in conjunction with the LOC 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 
risks by comparing aggregate 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 LOC by all 
applicable UFs. Short-term, intermediate-term, and long-term risks are 
evaluated by comparing aggregate exposure to the LOC to ensure that the 
margin of exposure (MOE) called for by the product of all applicable 
UFs is not exceeded.
    For non-threshold risks, the Agency assumes that any amount of 
exposure will lead to some degree of risk and estimates risk in terms 
of the probability of occurrence of additional adverse cases. 
Generally, cancer risks are considered non-threshold. 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/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm
.

    A summary of the toxicological endpoints for glufosinate ammonium 
used for human risk assessment is discussed in Unit III.B. of the final 
rule published in the Federal Register of September 29, 2003 (68 FR 
55833) (FRL-7327-9).

C. Exposure Assessment

    EPA concludes that the tolerance levels for combined residues of 
Glufosinate-ammonium are unchanged. The exposure assumptions discussed 
in the final rule published in the Federal Register of September 29, 
2003 (68 FR 55833) (FRL-7327-9) remain the same.

D. Safety Factor for Infants and Children

    A summary of the safety factor for infants and children for 
glufosinate ammonium is discussed in Unit III.D. of the final rule 
published in the Federal Register of September 29, 2003 (68 FR 55833) 
(FRL-7327-9)

E. Aggregate Risks and Determination of Safety

    Safety is assessed for acute and chronic risks by comparing 
aggregate exposure to the pesticide to the aPAD and cPAD. The aPAD and 
cPAD are calculated by dividing the LOC by all applicable UFs. For 
linear cancer risks, EPA calculates the probability of additional 
cancer cases given aggregate exposure. Short-term, intermediate-term, 
and long-term risks are evaluated by comparing aggregate exposure to 
the LOC to ensure that the MOE called for by the product of all 
applicable UFs is not exceeded.
    Consistent with FFDCA section 408(b)(2)(D), and the factors 
specified in section 408(b)(2)(D), 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 revision in 
the tolerance expressions for combined residues of glufosinate-ammonium 
and its metabolites. EPA's assessment of exposures and risks associated 
with establishing the tolerance are discussed in the Federal Register 
of September 29, 2003 (68 FR 55833) (FRL-7327-9).
     Accordingly EPA concludes that there is a reasonable certainty 
that no harm will result to the general population and to infants and 
children from aggregate exposure to glufosinate-ammonium residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology gas chromatography 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

    Since tolerances levels remain the same and since there are no new 
tolerances established, harmonization with CODEX, Canada or Mexico's 
MRLs is impacted.

C. Response to Comments

    Public comments were received from B. Sachau who objected to the 
proposed tolerances because of the amounts of pesticides already 
consumed and carried by the American population. She further indicated 
that testing conducted on animals have absolutely no validity and are 
cruel to the test animals. B. Sachau's comments contained no scientific 
data or evidence to rebut the Agency's conclusion that there is a 
reasonable certainty that no harm will result from aggregate exposure 
to glufosinate ammonium, including all anticipated dietary exposures 
and all other exposures for which there is reliable information. EPA

[[Page 72625]]

has responded to B. Sachau's generalized comments on numerous previous 
occasions. (January 7, 2005, 70 FR 1349) (October 29, 2004, 69 FR 
63083).

V. Conclusion

    Therefore, the tolerance regulation for the combined residues of 
glufosinate-ammonium and its metabolites expressed as butanoic acid, 2-
amino-4-(hydroxymethylphosphinyl)-, monoammonium salt, 2-acetamido-4-
methylphosphinico-butanoic acid and 3-methylphosphinico-propionic acid 
(expressed as glufosinate free acid equivalents), are revised by 
placing all the commodities listed Sec. 180.473 (a)(1) and (a)(2) 
together in Sec. 180.473 (a).

VI. Statutory and Executive Order Reviews

    This final rule establishes a tolerance 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 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).
