II. Summary of Petitioned-For Tolerance

    In the Federal Register of July 20, 2011 (76 FR 43231) (FRL-8880-
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 
0F7800) by BASF Corporation, P.O. Box 13528, Research Triangle Park, NC 
27709. The petition requested that EPA amend 40 CFR part 180 by raising 
tolerances for residues of the fungicide dimethomorph, in or on 
brassica, head and stem, subgroup 5A from 2.0 ppm to 5.0 ppm; brassica, 
leafy greens, subgroup 5B from 20.0 ppm to 30.0 ppm; green onion, 
subgroup 3B from 2.0 ppm to 11.0 ppm. The petition also requested that 
40 CFR part 180 be amended by establishing a tolerance for the residues 
of the fungicide dimethomorph, in or on vegetable, leafy at 16 ppm (PP 
0F7816). The notice

[[Page 26463]]

referenced a summary of the petition prepared by BASF Corporation, the 
registrant, which is available in the docket, http://www.regulations.gov. There were no comments received in response to the 
notice of filing.
    In the Federal Register of October 27, 2010 (75 FR 66092) (FRL-
8848-3), 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 
0F7751) by BASF Corporation, P.O. Box 13528, Research Triangle Park, NC 
27709. The petition requested that EPA establish a tolerance for 
residues of the fungicide dimethomorph, in or on grape at 3.5 ppm. The 
notice referenced a summary of the petition prepared by BASF 
Corporation, the registrant, which is available in the docket, http://www.regulations.gov. One comment was received on the notice of filing. 
EPA's response to these comments is discussed in Unit IV.C.
    Based upon review of the data supporting the petitions, EPA has 
revised the proposed tolerance level and commodity definition for 
vegetable, bulb, group 3 and removed the established tolerance for the 
regional registration for grape. Tolerances for the national 
registration for grape and onion, bulb subgroup 3-07A were lowered. 
Tolerances for brassica, head and stem, subgroup 5A; brassica, leafy 
greens, subgroup 5B; vegetable, leafy except brassica, group 4; onion, 
green, subgroup 3-07B were raised. Tolerances for grape, raisin were 
established for domestic registrations and were also raised. EPA is 
also establishing rotational crop tolerances for wheat, forage; wheat, 
hay; and wheat, straw. EPA has made various changes to the commodity 
definitions and tolerance levels sought in the petition and also is 
establishing rotational crop tolerances. The reason 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 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 dimethomorph including exposure 
resulting from the tolerances established by this action. EPA's 
assessment of exposures and risks associated with dimethomorph 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.
    Dimethomorph has low acute toxicity via the oral and dermal routes 
of exposure. Chronic risk is regulated based on effects seen in body 
weight decrements and liver effects in the female rat. There was no 
evidence of increased incidence of any neoplasms at the limit dose 
tested in carcinogenicity studies tested in rats and mice. Dimethomorph 
is classified as ``not likely'' to be a human carcinogen based on the 
lack of evidence of carcinogenicity in carcinogenicity studies in rats 
and mice. The available data for dimethomorph does not show evidence of 
neurotoxicity. There is a subchronic neurotoxicity study available 
which demonstrated no neurotoxic effects in the study. In addition, 
neither the subchronic nor chronic toxicity studies in rats or dogs, 
nor the developmental toxicity studies indicated that the nervous 
system was affected by treatment with dimethomorph.
    Specific information on the studies received and the nature of the 
adverse effects caused by dimethomorph 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 ``Dimethomorph: Human Health Risk 
Assessment to Support Amended Use on Grapes, Bulb Vegetables, Leafy 
Brassica Vegetables, and Leafy Vegetables,'' pp. 35-38 in docket ID 
number EPA-HQ-OPP-2011-0388.

B. Toxicological Points of Departure/Levels of Concern

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological points of departure (POD) and levels of 
concern to use in evaluating the risk posed by human exposure to the 
pesticide. For hazards that have a threshold below which there is no 
appreciable risk, the toxicological POD is used as the basis for 
derivation of reference values for risk assessment. PODs are developed 
based on a careful analysis of the doses in each toxicological study to 
determine the dose at which no adverse effects are observed (the NOAEL) 
and the lowest dose at which adverse effects of concern are identified 
(the LOAEL). Uncertainty/safety factors are used in conjunction with 
the POD to calculate a safe exposure level--generally referred to as a 
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe 
margin of exposure (MOE). 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 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 dimethomorph used for 
human risk assessment is shown in the Table this unit.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to dimethomorph, EPA considered exposure under the petitioned-
for tolerances as well as all existing dimethomorph tolerances in 40 
CFR 180.493. EPA assessed dietary exposures from dimethomorph 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 toxic effects 
attributable to a single dose were observed in the toxicological 
studies for dimethomorph; therefore, a quantitative acute dietary 
exposure assessment is unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the USDA 1994-1996 
and 1998 CSFII. As to residue levels in food, EPA assumed tolerance-
level residues and 100 percent crop treated (PCT). Dietary Evaluation 
Exposure Model (DEEM) default processing factors were used.
    iii. Cancer. Based on the data summarized in Unit III.A., 
dimethomorph has been classified as ``not likely'' to be a human 
carcinogen. EPA has concluded that dimethomorph does not pose a cancer 
risk to humans. Therefore, a dietary exposure assessment for the 
purpose of assessing cancer risk is unnecessary.
    iv. Anticipated residue and PCT information. EPA did not use 
anticipated residue and/or PCT information in the dietary assessment 
for dimethomorph. Tolerance level residues and/or 100 PCT were assumed 
for all food commodities.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for dimethomorph in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of dimethomorph. 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 dimethomorph for 
acute exposures are estimated to be 81.1 parts per billion (ppb) for 
surface water and 0.264 ppb for ground water.
    For chronic exposures for non-cancer assessments are estimated to 
be 24.7 ppb for surface water and 0.264 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 24.7 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). Dimethomorph 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 dimethomorph to share a common mechanism of 
toxicity with any other substances, and dimethomorph does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
dimethomorph 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 Web site 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 Food Quality 
Protection Act (FQPA) Safety Factor (SF). In applying this

[[Page 26465]]

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 available data did not 
provide evidence of any increased susceptibility in the offspring in 
either of the two developmental toxicity studies or in the 2-generation 
reproduction study. In either of these two studies toxicity was not 
seen in the offspring occurring at doses lower than in the parent in 
any of the studies. Additionally, the effects seen in the young were 
qualitatively similar to those in the parents.
    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 dimethomorph is complete.
    ii. There is no indication that dimethomorph is a neurotoxic 
chemical and there is no need for a developmental neurotoxicity study 
or additional UFs to account for neurotoxicity.
    iii. There is no evidence that dimethomorph results in increased 
susceptibility in in utero rats or rabbits in the prenatal 
developmental studies or in young rats in the 2-generation reproduction 
study.
    iv. There are no residual uncertainties identified in the exposure 
databases. The unrefined chronic dietary risk assessment used tolerance 
level residues, included modeled drinking water estimates, assumed 100 
PCT, and incorporated DEEM default processing factors. EPA made 
conservative (protective) assumptions in the ground and surface water 
modeling used to assess exposure to dimethomorph in drinking water. 
These assessments will not underestimate the exposure and risks posed 
by dimethomorph.

E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic dietary pesticide 
exposures are safe by comparing aggregate exposure estimates to the 
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA 
calculates the lifetime probability of acquiring cancer 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 appropriate PODs to ensure that an 
adequate MOE exists.
    1. Acute risk. An acute aggregate risk assessment takes into 
account acute exposure estimates from dietary consumption of food and 
drinking water. No adverse effect resulting from a single oral exposure 
was identified and no acute dietary endpoint was selected. Therefore, 
dimethomorph is not expected to pose an acute risk.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
dimethomorph from food and water will utilize 27% of the cPAD for 
children 1-2 years old the population group receiving the greatest 
exposure. There are no residential uses for dimethomorph and thus 
residential exposure to residues of dimethomorph is not expected.
    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). Dimethomorph 
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 dimethomorph 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). Dimethomorph 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 dimethomorph through food and water, which has already been 
addressed, and will not be greater than the chronic aggregate risk.
    5. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, dimethomorph is not expected to pose a cancer risk to humans.
    6. 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 dimethomorph residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    FAMS-002-04 which utilizes high pressure liquid chromatography with 
ultraviolet detection (HPLC/UV) 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; email address: 
residuemethods@epa.gov.

B. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S. 
tolerances with international standards whenever possible, consistent 
with U.S. food safety standards and agricultural practices. EPA 
considers the international maximum residue limits (MRLs) established 
by the Codex Alimentarius Commission (Codex), as required by FFDCA 
section 408(b)(4). The Codex Alimentarius is a joint United Nations 
Food and Agriculture Organization/World Health Organization food 
standards program, and it is recognized as an international food safety 
standards-setting organization in trade agreements to which the United 
States is a party. EPA may establish a tolerance that is different from 
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain 
the reasons for departing from the Codex level.
    The Codex has established MRLs for dimethomorph in or on grape at 2 
ppm; and grape, raisin at 5 ppm. These MRLs are different than the 
tolerances being established for dimethomorph in this action because 
the MRLs are based on residue data derived from Europe.

C. Response to Comments

    One comment was received from a private citizen (in reference to 
tolerance petition 0F7751) who encouraged the Agency to continue to 
reduce the risk to human health and the environment from pesticide 
usage. The Agency recognizes that some individuals believe that 
pesticide use should not be permitted. However, under the existing 
legal framework provided by section 408 of the Federal Food, Drug and 
Cosmetic Act (FFDCA), EPA is authorized to establish pesticide 
tolerances or exemptions where persons seeking such tolerances or 
exemptions have demonstrated that the pesticide meets the safety 
standard imposed by the statute.

D. Revisions to Petitioned-For Tolerances

    The crop group regulations (40 CFR 180.41) were recently amended 
pertaining to Crop Group 3--Bulb Vegetables, and the revised Crop group 
is designated Crop group 3-07 Bulb Vegetable. The revised crop group 
now contains two subgroups: Bulb, subgroup

[[Page 26466]]

3-07A and onion, green, subgroup 3-07B. Because BASF proposed to modify 
its existing Crop Group 3 tolerance by adding a revised green onion 
tolerance, EPA has determined it is appropriate to establish both 
onion, bulb subgroup 3-07A and onion, green, subgroup 3-07B tolerances 
rather than a Crop Group 3 tolerance and a green onion tolerance. Based 
on analysis of residue levels from crop field trail data and tolerance 
calculation procedures, EPA is setting the onion, bulb subgroup 3-07A 
tolerance at 0.6 ppm and the onion, green, subgroup 3-07B tolerance at 
15 ppm. EPA is removing the existing Crop Group 3 tolerance.
    Additionally, based on analysis of residue levels from crop field 
trail data and tolerance calculation procedures, EPA is raising 
tolerance levels for grape, raisin; brassica, head and stem, subgroup 
5A; brassica, leafy greens, subgroup 5B; and vegetable, leafy, except 
brassica, group 4. For the same reason, EPA is lowering the tolerance 
for grape. Additionally, because the Agency is amending the BASF 
registration to allow use on grapes in the U.S., EPA is removing the 
footnote in the tolerance stating that such a registration does not 
exist.
    Subsequent to the filing of the petition, the petitioner requested 
that the Agency establish tolerances in cereal grain commodities 
(forage, hay and straw) that are rotated to fields following use 
dimethomorph on commodities covered by the tolerances established in 
this action. The Agency determined that rotated crop tolerances would 
be appropriate for wheat, forage; wheat, hay; and wheat, straw.

V. Conclusion

    Therefore, amended tolerances are established for residues of 
dimethomorph, in or on brassica, head and stem, subgroup 5A at 6.0 ppm; 
brassica, leafy greens, subgroup 5B at 30.0 ppm; onion, bulb subgroup 
3-07A at 0.6 ppm; onion, green, subgroup 3-07B at 15.0 ppm; grape at 
3.0 ppm; and grape, raisin at 7.0 ppm. A tolerance is established for 
residues of dimethomorph, in or on vegetable, leafy except brassica, 
group 4 at 30.0 ppm. This regulation also establishes tolerances for 
the indirect or inadvertent residues of dimethomorph, in or on wheat, 
forage at 0.15 ppm; wheat hay at 0.15 ppm and wheat, straw at 0.4 ppm. 
Furthermore, this regulation removes established tolerances on 
vegetable, bulb, group 3 and footnote pertaining the lack of a 
registration for use on grapes.

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances under FFDCA section 408(d) 
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 FFDCA section 408(d), 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 FFDCA section 408(n)(4). 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) (Pub. L. 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).
