SUPPLEMENTARY INFORMATION: In the Federal Register of January 20, 1999
(64 FR 3099) (FRL-6053-5), 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 of 1996 (FQPA) (Pub. L. 104-
170 announcing the filing of a pesticide petition (PP 5F4554) for
tolerance by Zeneca Ag. Products, 1800 Concord Pike, P. O. Box 15458,
Wilmington, DE 19850-5458. This notice included a summary of the
petition prepared by Zeneca Ag Products, the registrant. There were no
comments received in response to the notice of filing.
The petition requested that 40 CFR 180.489 be amended by
establishing a tolerance for residues of the herbicide sulfosate, in or
on wheat bran at 2.5 parts per million (ppm) (of which no more than
0.75 ppm is trimethylsulfonium (TMS)), wheat grain at 0.75 ppm (of
which no more than 0.25 ppm is TMS), wheat forage at 35 ppm (of which
no more than 30 ppm is TMS), wheat hay at 85 ppm (of which no more than
80 ppm is TMS), wheat shorts at 1.5 ppm (of which no more than 0.5 ppm
is TMS), wheat straw at 1.0 ppm (of which no more than 0.5 ppm is TMS),
the pome fruit group at 0.05 ppm; in cattle, goat, hog, sheep, and
horse liver at 0.5 ppm, in cattle, goat, hog, sheep, and horse meat by-
products, except liver at 2.5 ppm; to increase the tolerance in cattle,
goat, hog, sheep, and horse meat from 0.2 to 0.4 ppm and in milk from
0.2 to 0.5 ppm.
In the Federal Register of September 11, 1998 (63 FR 48597) (FRL-
6026-6), EPA issued a final rule for establishment of tolerances for
sulfosate on corn, soybean eggs, milk, cattle, goat, hog, sheep, and
horse commodities. Sulfosate residues, at the above levels, resulting
from consumption of wheat, pome fruit, meat, milk, poultry, and eggs
were included in the dietary and risk assessments conducted to
establish these tolerances.

I. Background and Statutory Findings

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(b)(2)(A)(ii) 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)
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 and a complete description of
the risk assessment process, see the final rule on Bifenthrin Pesticide
Tolerances (62 FR 62961, November 26, 1997) (FRL-5754-7).

II. Aggregate Risk Assessment and Determination of Safety

Consistent with 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 sulfosate
and to make a determination on aggregate exposure, consistent with
section 408(b)(2), for a tolerance for residues of sulfosate on wheat
bran at 2.5 parts per million (ppm) (of which no more than 0.75 ppm is
trimethylsulfonium (TMS)), wheat grain at 0.75 ppm (of which no more
than 0.25 ppm is TMS), wheat forage at 35 ppm (of which no more than 30
ppm is TMS), wheat hay at 85 ppm (of which no more than 80 ppm is TMS),
wheat shorts at 1.5 ppm (of which no more than 0.5 ppm is TMS), wheat
straw at

[[Page 22803]]

1.0 ppm (of which no more than 0.5 ppm is TMS), the pome fruit group at
0.05 ppm; in cattle, goat, hog, sheep, and horse liver at 0.5 ppm, in
cattle, goat, hog, sheep, and horse meat by-products, except liver at
2.5 ppm; to increase the tolerance in cattle, goat, hog, sheep, and
horse meat from 0.2 to 0.4 ppm and in milk from 0.2 to 0.5 ppm. EPA's
assessment of the dietary 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. The nature of the toxic effects caused by sulfosate are
discussed in Unit II. A. of the Federal Register notice of September
11, 1998 (63 FR 48597). Please note that this unit included a
typographical error. In the discussion of the feeding carcinogenicity
study in mice, ``79'' should have been ``7.9'' in the following phrase:
``In addition, there was increased incidence of white matter
degeneration in the lumbar region of the spinal cord (males only) (2,
3, 4, 4, 79% response, controls to high dose)...''

B. Toxicological Endpoints

The toxicological endpoints for sulfosate are discussed in Unit II.
B. of the Federal Register notice of September 11, 1998 (63 FR 48597).

C. Exposures and Risks

The exposures and risks due to consumption of sulfosate, including
residues in wheat and pome fruit, are discussed in Unit II. C. of the
Federal Register notice of September 11, 1998 (63 FR 48597).

D. Aggregate Risks and Determination of Safety for U.S. Population

The aggregate risks and determination of safety for the U.S.
population resulting from use of sulfosate are discussed in Unit II. D.
of the Federal Register notice of September 11, 1998 (63 FR 48597).

E. Aggregate Risks and Determination of Safety for Infants and Children

The aggregate risks and determination of safety for infants and
children resulting from use of sulfosate are discussed in Unit II. E.
of the Federal Register notice of September 11, 1998 (63 FR 48597).

III. Other Considerations

A. Metabolism In Plants and Animals

The nature of the residues in plants and animals is understood. EPA
has determined that the tolerance expression for sulfosate must include
both of the parent ions.

B. Analytical Enforcement Methodology

Analytical enforcement methodology for sulfosate is discussed in
Unit III. B. of the Federal Register notice of September 11, 1998 (63
FR 48597).

C. Magnitude of Residues

The crop field trial data are adequate to support these tolerances.

D. International Residue Limits

There are no Codex, Canadian or Mexican tolerances or maximum
residue limits for residues of sulfosate in the subject crops.
Therefore, a compatibility issue is not relevant to the proposed
tolerances.

E. Rotational Crop Restrictions

EPA has previously reviewed two confined rotational crop studies
for sulfosate and concluded that rotational crop restrictions were not
required.

IV. Conclusion

Therefore, the tolerances are established for residues of sulfosate
on wheat bran at 2.5 parts per million (ppm) (of which no more than
0.75 ppm is trimethylsulfonium (TMS)), wheat grain at 0.75 ppm (of
which no more than 0.25 ppm is TMS), wheat forage at 35 ppm (of which
no more than 30 ppm is TMS), wheat hay at 85 ppm (of which no more than
80 ppm is TMS), wheat shorts at 1.5 ppm (of which no more than 0.5 ppm
is TMS), wheat straw at 1.0 ppm (of which no more than 0.5 ppm is TMS),
the pome fruit group at 0.05 ppm; in cattle, goat, hog, sheep, and
horse liver at 0.5 ppm, in cattle, goat, hog, sheep, and horse meat by-
products, except liver at 2.5 ppm. Further, the tolerances are
increased tolerance in cattle, goat, hog, sheep, and horse meat from
0.2 to 0.4 ppm and in milk from 0.2 to 0.5 ppm.

V. Objections and Hearing Requests

The new FFDCA section 408(g) provides essentially the same process
for persons to ``object'' to a tolerance regulation as was provided in
the old section 408 and in section 409. However, the period for filing
objections is 60 days, rather than 30 days. EPA currently has
procedural regulations which govern the submission of objections and
hearing requests. These regulations will require some modification to
reflect the new law. However, until those modifications can be made,
EPA will continue to use those procedural regulations with appropriate
adjustments to reflect the new law.
Any person may, by June 28, 1999, file written objections to any
aspect of this regulation and may also request a hearing on those
objections. Objections and hearing requests must be filed with the
Hearing Clerk, at the address given under the ``ADDRESSES'' section (40
CFR 178.20). A copy of the objections and/or hearing requests filed
with the Hearing Clerk should be submitted to the OPP docket for this
regulation. The objections submitted must specify the provisions of the
regulation deemed objectionable and the grounds for the objections (40
CFR 178.25). Each objection must be accompanied by the fee prescribed
by 40 CFR 180.33(i). EPA is authorized to waive any fee requirement
``when in the judgement of the Administrator such a waiver or refund is
equitable and not contrary to the purpose of this subsection.'' For
additional information regarding tolerance objection fee waivers,
contact James Tompkins, Registration Division (7505C), Office of
Pesticide Programs, Environmental Protection Agency, 401 M St., SW.,
Washington, DC 20460. Office location, telephone number, and e-mail
address: Rm. 239, Crystal Mall #2, 1921 Jefferson Davis Hwy.,
Arlington, VA, (703) 305-5697, tompkins.jim@epa.gov. Requests for
waiver of tolerance objection fees should be sent to James Hollins,
Information Resources and Services Division (7502C), Office of
Pesticide Programs, Environmental Protection Agency, 401 M St., SW.,
Washington, DC 20460.
If a hearing is requested, the objections must include a statement
of the factual issues on which a hearing is requested, the requestor's
contentions on such issues, and a summary of any evidence relied upon
by the requestor (40 CFR 178.27). A request for a hearing will be
granted if the Administrator determines that the material submitted
shows the following: There is genuine and substantial issue of fact;
there is a reasonable possibility that available evidence identified by
the requestor would, if established, resolve one or more of such issues
in favor of the requestor, taking into account uncontested claims or
facts to the contrary; and resolution of the factual issues in the
manner sought by the requestor would be adequate to justify the action
requested (40 CFR 178.32). Information submitted in connection with an
objection or hearing request may be claimed confidential by marking

[[Page 22804]]

any part or all of that information as CBI. Information so marked will
not be disclosed except in accordance with procedures set forth in 40
CFR part 2. A copy of the information that does not contain CBI must be
submitted for inclusion in the public record. Information not marked
confidential may be disclosed publicly by EPA without prior notice.

VI. Public Record and Electronic Submissions

EPA has established a record for this regulation under docket
control number [OPP-300849] (including any comments and data submitted
electronically). A public version of this record, including printed,
paper versions of electronic comments, which does not include any
information claimed as CBI, is available for inspection from 8:30 a.m.
to 4 p.m., Monday through Friday, excluding legal holidays. The public
record is located in Room 119 of the Public Information and Records
Integrity Branch, Information Resources and Services Division (7502C),
Office of Pesticide Programs, Environmental Protection Agency, Crystal
Mall #2, 1921 Jefferson Davis Hwy., Arlington, VA.
Objections and hearing requests may be sent by e-mail directly to
EPA at:
opp-docket@epa.gov.

E-mailed objections and hearing requests must be submitted as an
ASCII file avoiding the use of special characters and any form of
encryption.
The official record for this regulation, as well as the public
version, as described in this unit will be kept in paper form.
Accordingly, EPA will transfer any copies of objections and hearing
requests received electronically into printed, paper form as they are
received and will place the paper copies in the official record which
will also include all comments submitted directly in writing. The
official record is the paper record maintained at the Virginia address
in ``ADDRESSES'' at the beginning of this document.

VII. Regulatory Assessment Requirements

A. Certain Acts and Executive Orders

This final rule establishes a tolerance under section 408(d) of the
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). 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) (Pub. L. 104-4). Nor does
it require any prior consultation as specficed by Executive Order
12875, entitled Enhancing the Intergovernmental Partnership (58 FR
58093, October 28, 1993), or special considerations as required by
Executive Order 12898, entitled Federal Actions to Address
Environmental Justice in Minority Populations and Low-Income
Populations (59 FR 7629, February 16, 1994), or require OMB review in
accordance with Executive Order 13045, entitled Protection of Children
from Environmental Health Risks and Safety Risks (62 FR 19885, April
23, 1997).
In addition, since tolerances and exemptions that are established
on the basis of a petition under FFDCA section 408(d), such as the
[tolerance/exemption] 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. Nevertheless, the Agency
previously assessed whether establishing tolerances, exemptions from
tolerances, raising tolerance levels or expanding exemptions might
adversely impact small entities and concluded, as a generic matter,
that there is no adverse economic impact. The factual basis for the
Agency's generic certification for tolerance actions published on May
4, 1981 (46 FR 24950), and was provided to the Chief Counsel for
Advocacy of the Small Business Administration.

B. Executive Order 12875

Under Executive Order 12875, entitled Enhancing the
Intergovernmental Partnership (58 FR 58093, October 28, 1993), EPA may
not issue a regulation that is not required by statute and that creates
a mandate upon a State, local or tribal government, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by those governments. If the mandate is unfunded, EPA
must provide to OMB a description of the extent of EPA's prior
consultation with representatives of affected State, local, and tribal
governments, the nature of their concerns, copies of any written
communications from the governments, and a statement supporting the
need to issue the regulation. In addition, Executive Order 12875
requires EPA to develop an effective process permitting elected
officials and other representatives of State, local, and tribal
governments ``to provide meaningful and timely input in the development
of regulatory proposals containing significant unfunded mandates.''
Today's rule does not create an unfunded Federal mandate on State,
local, or tribal governments. The rule does not impose any enforceable
duties on these entities. Accordingly, the requirements of section 1(a)
of Executive Order 12875 do not apply to this rule.

C. Executive Order 13084

Under Executive Order 13084, entitled Consultation and Coordination
with Indian Tribal Governments (63 FR 27655, May 19, 1998), EPA may not
issue a regulation that is not required by statute, that significantly
or uniquely affects the communities of Indian tribal governments, and
that imposes substantial direct compliance costs on those communities,
unless the Federal government provides the funds necessary to pay the
direct compliance costs incurred by the tribal governments. If the
mandate is unfunded, EPA must provide OMB, in a separately identified
section of the preamble to the rule, a description of the extent of
EPA's prior consultation with representatives of affected tribal
governments, a summary of the nature of their concerns, and a statement
supporting the need to issue the regulation. In addition, Executive
Order 13084 requires EPA to develop an effective process permitting
elected officials and other representatives of Indian tribal
governments ``to provide meaningful and timely input in the development
of regulatory policies on matters that significantly or uniquely affect
their communities.''
Today's rule does not significantly or uniquely affect the
communities of Indian tribal governments. This action does not involve
or impose any requirements that affect Indian tribes. Accordingly, the
requirements of section 3(b) of Executive Order 13084 do not apply to
this rule.

VIII. Submission to Congress and the Comptroller General

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the Agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and 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

[[Page 22805]]

the Comptroller General of the United States prior to publication of
the rule in the Federal Register. This rule is not a ``major rule'' as
defined by 5 U.S.C. 804(2).
