ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 180
[EPA-HQ-OPP-2006-0205; FRL-8113-8]

Halosulfuron-methyl; Pesticide Tolerance

AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation establishes tolerances for residues of
halosulfuron-methyl in or on the commodities alfalfa, forage at 1.0
parts per million (ppm) and alfalfa, hay at 2.0 ppm. Gowan Company
requested these tolerances under the Federal Food, Drug, and Cosmetic
Act (FFDCA), as amended by the Food Quality Protection Act of 1996
(FQPA). The Agency is also correcting the tolerance expression for 40
CFR 180.479(a)(1) with this regulation. The tolerance expression is
being corrected because the metabolites were inadvertently deleted from
the most recent edition of 40 CFR 180.479.

DATES: This regulation is effective February 28, 2007. Objections and
requests for hearings must be received on or before April 30, 2007, and
must be filed in accordance with the instructions provided in 40 CFR
part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Background and Statutory Findings

    In the Federal Register of December 20, 2006 (71 FR 76321) (FRL-
8104-4), 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
2F2469) by Gowan Company, P. O. Box 5569, Yuma, AZ 85366. The petition
requested that 40 CFR 180.479(a)(2) be amended by establishing a
tolerance for residues of the herbicide halosulfuron methyl, methyl 5-
[(4, 6-dimethoxy-2-pyrimidinyl)amino]
carbonylaminosulfonyl-3-chloro-1-
methyl-1H-pyrazole-4-carboxylate in or on the raw agricultural
commodities alfalfa, forage at 1.0 ppm and alfalfa, hay at 2.0 ppm. The
Agency also proposed that the tolerance expression for 40 CFR
180.479(a)(1) be corrected to read ``Tolerances are established for
residues of the herbicide halosulfuron-methyl, methyl 5-[(4,6-
dimethoxy-2-pyrimidiny)amino]
carbonylaminosulfonyl-3-chloro-1-methyl-
1H-pyrazole-4-caboxylate, and its metabolites determined as 3-chloro-1-
methyl-5-sulfamoylpyrazole-4-carboxylic acid, expressed as
halosulfuron-methyl equivalents in or on the raw agricultural
commodities listed in the table in this unit.'' That notice referenced
a summary of the petition prepared by Gowan Company, the registrant
that has been included in the public docket. There were no comments
received in response to the notice of filing.
    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....''
    EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. For further discussion of the
regulatory requirements of section 408 of FFDCA and a complete
description of the risk assessment process, see 
http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm.

III. Aggregate Risk Assessment and Determination of Safety

    Consistent with 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, consistent with section
408(b)(2) of FFDCA, for a tolerance for residues of halosulfuron-methyl
the commodities alfalfa, forage at 1.0 ppm and alfalfa, hay at 2.0 ppm.
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 toxic effects caused by halosulfuron-methyl 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 0002 (pages 16-20) in docket ID
number EPA-HQ-OPP-2006-0205.

B. Toxicological Endpoints

    For hazards that have a threshold below which there is no
appreciable risk, the dose at which the NOAEL from the toxicology study
identified as appropriate for use in risk assessment is used to
estimate the toxicological level of concern (LOC). However, the LOAEL
is sometimes used for risk assessment if no NOAEL was achieved in the
toxicology study selected. An uncertainty factor (UF) is applied to
reflect 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.
    The linear default risk methodology (Q*) is the primary method
currently used by the Agency to quantify non-threshold hazards such as
cancer. The Q* approach assumes that any amount of exposure will lead
to some degree of cancer risk, estimates risk in terms of the
probability of occurrence of additional cancer cases. More information
can be found on the general principles EPA uses in risk
characterization at http://www.epa.gov/pesticides/health/human.htm.
    A summary of the toxicological endpoints for halosulfuron-methyl
used for human risk assessment can be found at http://www.regulations.gov.
in document 0002 (pages 34-35) in docket ID number EPA-HQ-OPP-2006-0205.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. Tolerances have been
established (40 CFR 180.479) for the residues of halosulfuron-methyl,
in or on a variety of raw agricultural commodities. Tolerances have
been established for halosulfuron-methyl and its metabolites determined
as 3-chlore-1-methyl-5-sulfamoylpyrazole-4-carboxylic acid, expressed
as halosulfuron-methyl equivalents in or on meat by products of cattle,
goat, hog, horse, and sheep. Risk assessments were conducted by EPA to
assess dietary exposures from halosulfuron-methyl 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.
    In conducting the acute dietary exposure assessment EPA used the
Dietary Exposure Evaluation Model software with the Food Commodity
Intake Database (DEEM-FCID\TM\), which incorporates food consumption
data as reported by respondents in the U.S. Department of Agriculture
(USDA) 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by

[[Page 8925]]

Individuals (CSFII), and accumulated exposure to the chemical for each
commodity. The following assumptions were made for the chronic exposure
assessments: Tolerance level residues and 100 percent crop treated
(PCT) for all existing and proposed uses. Percent crop treated or
anticipated residues were not used.
    The acute dietary exposure estimates are provided for females 13-50
years old only. The existing data showed no indication that
halosulfuron-methyl could cause adverse effects in the general
population based upon a single dose. Thus there is no concern for acute
dietary exposure to the general population.
    ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the DEEM-FCID\TM\, which incorporates food
consumption data as reported by respondents in the USDA 1994-1996 and
1998 Nationwide CSFII, and accumulated exposure to the chemical for
each commodity. The following assumptions were made for the chronic
exposure assessments: A chronic dietary analysis for halosulfuron-
methyl was conducted using tolerance level residues and 100 PCT for all
existing and proposed uses. Percent crop treated or anticipated
residues were not used.
    iii. Cancer. Halosulfuron-methyl is classified as a ``not likely''
human carcinogen based on a lack of evidence of carcinogenicity in male
and female mice and rats following long-term dietary administration.
Therefore, halosulfuron-methyl is not expected to pose a cancer risk
for humans.
    2. Dietary exposure from drinking water. The Agency lacks
sufficient monitoring exposure data to complete a comprehensive dietary
exposure analysis and risk assessment for halosulfuron-methyl in
drinking water. Because the Agency does not have comprehensive
monitoring data, drinking water concentration estimates are made by
reliance on simulation or modeling taking into account data on the
physical characteristics of halosulfuron-methyl. Further information
regarding EPA drinking water models used in pesticide exposure
assessment can be found at http://www.epa.gov/oppefed1/models/water/index.
    Based on the FQPA Index Reservoir Screening Tool (FIRST) and
screening concentration in ground water (SCI-GROW) models, the
estimated environmental concentrations (EECs) of halosulfuron-methyl
for acute exposures are estimated to be 105 parts per billion (ppb) for
surface water and 0.065 ppb for ground water. The EECs for chronic
exposures are estimated to be 105 ppb for surface water and 0.065 ppb
for ground water.
    Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model (DEEM-FCID). For acute and
chronic dietary risk assessment, the annual average concentration of
105 ppb was used to access 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).
    Halosulfuron-methyl is currently registered for use on the
following residential non-dietary sites: Application to commercial and
residential turf and on other non-crop sites including airports,
cemeteries, fallow areas, golf courses, landscaped areas, public
recreation areas, residential property, roadsides, school grounds, sod
or turf seed farms, sports fields, and landscaped areas with
established woody ornamentals. Application may be by commercial
applicator or homeowner. Residential handlers may receive short-term
dermal and inhalation exposure to halosulfuron-methyl when mixing,
loading, and applying the formulations. Adults and children may be
exposed to halosulfuron-methyl residues through dermal contact with
turf during postapplicaton activities. A residential exposure and risk
assessment was previously conducted for these exposure scenarios.
Combined margins of exposure (MOEs) for adults' and children's dermal
exposure and toddlers' incidental exposure from all residential
activities are greater than the Agency's LOC of 100, and therefore are
not of concern. These risk assessments are fully discussed in Unit
III.E.3. of a final rule published in the Federal Register of September
20, 2002 (67 FR 59182) (FRL-7200-8).
    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.''
    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 halosulfuron-methyl and
any other substances and halosulfuron-methyl 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
halosulfuron-methyl 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 the policy statements
released by EPA's Office of Pesticide Programs concerning common
mechanism determinations and procedures for cumulating effects from
substances found to have a common mechanism on EPA's website at 
http://www.epa.gov/pesticides/cumulative.

D. Safety Factor for Infants and Children

    1.In general. Section 408 of 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 based on reliable data 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
MOE analysis or through using uncertainty (safety) factors in
calculating a dose level that poses no appreciable risk to humans. In
applying this provision, EPA either retains the default value of 10X
when reliable data do not support the choice of a different factor, or,
if reliable data are available, EPA uses a different additional safety
factor (SF) value based on the use of traditional UFs and/or special
FQPA SFs, as appropriate.
    2. Prenatal and postnatal sensitivity. There is no evidence of
increased susceptibility of young rats in the reproduction study with
halosulfuron-methyl. Although there is qualitative evidence of
increased susceptibility in the prenatal developmental studies in rats
and rabbits, the Agency did not identify any residual uncertainties
after establishing toxicity endpoints and traditional UFs to be used in
the risk assessment of halosulfuron-methyl.
    3. Conclusion. EPA determined that the 10X SF to protect infants
and children should be removed. The FQPA factor is reduced to 1X based
on the following findings.
    i. The toxicity database for halosulfuron-methyl is complete.
Although EPA previously required

[[Page 8926]]

submission of a developmental neurotoxicity, that requirement has been
waived based on a review of the entire database including recently
submitted acute and subchronic neurotoxicity studies. This review
showed that there was no evidence of clinical signs of neurotoxicity,
brain weights changes, or neuropathology in the subchronic (including
the neurotoxicity study) or chronic studies in rats, mice, or dogs. The
acute neurotoxicity study showed some minor, transient functional
observational battery (FOB) effects on day 0 (none statistically
significant) at the limit dose with no effects persisting past day 0.
There were not effects on brain weights or neuropathology. The observed
FOB effects are not considered attributable to a direct neurotoxic
response as they are minor, transient and occurred at the limit dose.
    ii. There is no evidence of increased susceptibility of young rats
in the reproduction study with halosulfuron-methyl. Although there is
qualitative evidence of increased susceptibility in the prenatal
developmental studies in rats and rabbits, the Agency did not identify
any residual uncertainties after establishing toxicity endpoints and
traditional UFs to be used in the risk assessment of halosulfuron-
methyl. The degree of concern for pre and/or postnatal toxicity is low.
    iii. 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. Conservative ground water and
surface water modeling estimates were used in the risk assessments.
Agency Residential standard operational proceedures (SOPs) are used to
assess post-application exposure to children as well as incidental oral
exposure of toddlers. These assessments will not underestimate the
exposure and risks posed by halosulfuron-methyl.

E. Aggregate Risks and Determination of Safety

    1. Acute risk. The acute aggregate risk assessment is provided for
females 13-50 years old only. The existing data showed no indication
that halosulfuron-methyl could cause adverse effects in the general
population based upon a single dose. Thus there is no concern for acute
dietary exposure to the general population. Using the exposure
assumptions discussed in this Unit III.C. for acute exposure, the acute
dietary exposure from food and water to halosulfuron-methy will occupy
1.0% of the acute Population Adjusted Dose (aPAD) for females 13 years
and older. EPA does not expect the acute aggregate exposure to exceed
100% of the aPAD.
    2. Chronic risk. Using the exposure assumptions described in Unit
III.C. for chronic exposure, EPA has concluded that exposure to
halosulfuron-methyl from food and water will utilize 3.0% of the
chronic Population Adjusted Dose (cPAD) for the U.S. population, 8.0 of
the cPAD for all infants (< 1 year old), and 4.0% of the cPAD for
children 1-2 years old and children 3-5 years old. Based the use
pattern, chronic residential exposure to residues of halosulfuron-
methyl is not expected. EPA does not expect the aggregate exposure to
exceed 100% of the cPAD.
    3. Short-term risk. Short-term aggregate exposure takes into
account residential exposure plus chronic exposure to food and water
(considered to be a background exposure level).
    Halosulfuron-methyl is currently registered for use that could
result in short-term residential exposure and the Agency has determined
that it is appropriate to aggregate chronic food and water and short-
term exposures for halosulfuron-methyl.
    A short-term risk assessment is required for adults because there
is a residential handler exposure scenario. In addition, a short-term
risk assessment is required for infants and children because there is a
residential post-application exposure scenario for infants and children.
    Using the exposure assumptions described in Unit III.C. for short-
term exposures, EPA has concluded that food and residential exposures
aggregated result in aggregate MOEs ranging from 2,400 to 4,400. The
MOE for the U.S. population is 4,300. The most highly exposed subgroup
was all infants (less than 1 year old with an MOE of 2,400. These
aggregate MOEs do not exceed the Agency's LOC for aggregate exposure to
food and residential uses. EPA does not expect short-term aggregate
exposure to exceed the Agency's LOC.
    4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account residential exposure plus chronic exposure to food
and water (considered to be a background exposure level).
    Halosulfuron-methyl is currently registered for use(s) that could
result in intermediate-term residential exposure and the Agency has
determined that it is appropriate to aggregate chronic food and water
and intermediate-term exposures for halosulfuron methyl.
    An intermediate-term risk assessment is required for adults because
there is a residential handler exposure scenario. In addition, an
intermediate-term risk assessment is required for infants and children
because there is a residential post-application exposure scenario for
infants and children.
    As an additional protective measure, residential handler exposures
were included in the intermediate-term aggregate risk assessment,
although residential exposure over the intermediate-term (more than 30
days) is unlikely.
    Using the exposure assumptions described is Unit III.E. for
intermediate-term exposures; EPA has concluded that food and
residential exposures aggregated result in aggregate MOEs ranged from
480 to 560. The MOEs for the U.S. population is 480. The most highly
exposed children's subgroup was all infants (less than 1 year old) with
a MOE of 560. These aggregate MOEs do not exceed the Agency's LOC for
aggregate exposure to food and residential uses. EPA does not expect
intermediate-term aggregate exposure to exceed the Agency's LOC.
    5. Aggregate cancer risk for U.S. population. Halosulfuron-methyl
is classified as ``not likely to be carcinogenic to humans'' based on
the lack of evidence for carcinogenicity in mice and rats following
long-term dietary administration. Therefore halosulfuron-methyl is not
expected to pose a cancer risk for 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 and to infants and children from aggregate
exposure to halosulfuron-methyl residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (gas chromatography with a
nitrogen specific detector) 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 currently no established Codex, Canadian, or Mexican maximum
residue levels (MRLs) for halosulfuron-methyl in or on alfalfa, forage or
alfalfa, hay. International harmonization is therefore not an issue.

V. Conclusion

    Therefore, the tolerance is established for residues of
halosulfuron methyl, methyl 5-[(4, 6-dimethoxy-2-pyrimidinyl)amino]

[[Page 8927]]

carbonylaminosulfonyl-3-chloro-1-methyl-1H-pyrazole-4-carboxylate in or
on the raw agricultural commodities alfalfa, forage at 1.0 ppm and
alfalfa, hay at 2.0 ppm (40 CFR 180.479(a)(2)). The Agency is also
correcting the tolerance expression for 40 CFR 180.479(a)(1) to read
``Tolerances are established for residues of the herbicide
halosulfuron-methyl, methyl 5-[(4,6-dimethoxy-2-pyrimidiny)amino]
carbonylaminosulfonyl-3-chloro-1-methyl-1H-pyrazole-4-caboxylate, and
its metabolites determined as 3-chloro-1-methyl-5-sulfamoylpyrazole-4-
carboxylic acid, expressed as halosulfuron-methyl equivalent, in or on
the raw agricultural commodities listed in the table in this unit.''

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 due to its lack of
significance, 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). 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., or 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). 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); or OMB review or any Agency action under Executive
Order 13045, entitled Protection of Children from Environmental Health
Risks and Safety Risks (62 FR 19885, April 23, 1997). 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). 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. In addition, the Agency has determined that this
action will not have a substantial direct effect on States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government, as specified in Executive Order 13132, entitled
Federalism(64 FR 43255, August 10, 1999). Executive Order 13132
requires EPA to develop an accountable process to ensure ``meaningful
and timely input by State and local officials in the development of
regulatory policies that have federalism implications.'' ``Policies
that have federalism implications'' is defined in the Executive order
to include regulations that have ``substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government.'' This final rule directly regulates
growers, food processors, food handlers, and food retailers, not
States. This action does not alter the relationships or distribution of
power and responsibilities established by Congress in the preemption
provisions of section 408(n)(4) of FFDCA. For these same reasons, the
Agency has determined that this rule does not have any ``tribal
implications'' as described in Executive Order 13175, entitled
Consultation and Coordination with Indian Tribal Governments (59 FR 22951,
November 6, 2000). Executive Order 13175, requires EPA to
develop an accountable process to ensure ``meaningful and timely input
by tribal officials in the development of regulatory policies that have
tribal implications.'' ``Policies that have tribal implications'' is
defined in the Executive order to include regulations that have
``substantial direct effects on one or more Indian tribes, on the
relationship between the Federal Government and the Indian tribes, or
on the distribution of power and responsibilities between the Federal
Government and Indian tribes.'' This rule will not have substantial
direct effects on tribal governments, on the relationship between the
Federal Government and Indian tribes, or on the distribution of power
and responsibilities between the Federal Government and Indian tribes,
as specified in Executive Order 13175. Thus, Executive Order 13175 does
not apply to this rule.

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).
