40 CFR Part 180

[EPA-HQ-OPP-2011-0736; FRL-9905-44]

D-mannose; Exemption From the Requirement of a Tolerance

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This regulation establishes an exemption from the requirement 
of a tolerance for residues of D-mannose (CAS Reg. No. 3458-28-4) when 
used as an inert ingredient (sequestrant, binder, or filler) in 
pesticide formulations applied pre-harvest to growing crops. ISK 
Biosciences Corporation submitted a petition to EPA under the Federal 
Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an 
exemption from the requirement of a tolerance. This regulation 
eliminates the need to establish a maximum permissible level for 
residues of D-mannose.

DATES: This regulation is effective February 7, 2014. Objections and 
requests for hearings must be received on or before April 8, 2014, and 
must be filed in accordance with the instructions provided in 40 CFR 
part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

ADDRESSES: The docket for this action, identified by docket 
identification (ID) number EPA-HQ-OPP-2011-0736, is available at http://www.regulations.gov or at the Office of Pesticide Programs

II. Petition for Exemption

    In the Federal Register of October 5, 2011 (76 FR 61647) (FRL-8890-
5), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 
346a, announcing the filing of a pesticide petition (PP 1E7903) by ISK 
Biosciences Corporation, 7470 Auburn Road, Suite A, Concord, OH 44077. 
The petition requested that 40 CFR 180.920 be amended by establishing 
an exemption from the requirement of a tolerance for residues of D-
mannose (CAS Reg. No. 3458-28-4) when used as an inert ingredient 
(sequestrant, binder or filler) in pesticide formulations applied 
preharvest to growing crops. That document referenced a summary of the 
petition prepared by ISK Biosciences Corporation, the petitioner, which 
is available in the docket, http://www.regulations.gov. There were no 
comments received in response to the notice of filing.

III. Inert Ingredient Definition

    Inert ingredients are all ingredients that are not active 
ingredients as defined in 40 CFR 153.125 and include, but are not 
limited to, the following types of ingredients (except when they have a 
pesticidal efficacy of their own): Solvents such as alcohols and 
hydrocarbons; surfactants such as polyoxyethylene polymers and fatty 
acids; carriers such as clay and diatomaceous earth; thickeners such as 
carrageenan and modified cellulose; wetting, spreading, and dispersing 
agents; propellants in aerosol dispensers; microencapsulating agents; 
and emulsifiers. The term ``inert'' is not intended to imply 
nontoxicity; the ingredient may or may not be chemically active. 
Generally, EPA has exempted inert ingredients from the requirement of a 
tolerance based on the low toxicity of the individual inert 
ingredients.

IV. Aggregate Risk Assessment and Determination of Safety

    Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an 
exemption from the requirement for 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 establishes exemptions from the requirement of a tolerance only 
in those cases where it can be clearly demonstrated that the risks from 
aggregate exposure to pesticide chemical residues under reasonably 
foreseeable circumstances will pose no appreciable risks to human 
health. In order to determine the risks from aggregate exposure to 
pesticide inert ingredients, the Agency considers the toxicity of the 
inert in conjunction with possible exposure to residues of the inert 
ingredient through food, drinking water, and through other exposures 
that

[[Page 7403]]

occur as a result of pesticide use in residential settings. If EPA is 
able to determine that a finite tolerance is not necessary to ensure 
that there is a reasonable certainty that no harm will result from 
aggregate exposure to the inert ingredient, an exemption from the 
requirement of a tolerance may be established.
    Consistent with FFDCA section 408(c)(2)(A), and the factors 
specified in FFDCA section 408(c)(2)(B), 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 D-mannose including exposure 
resulting from the exemption established by this action. EPA's 
assessment of exposures and risks associated with D-mannose follows.

A. Toxicological Profile

    EPA has evaluated the available toxicity data and considered their 
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. EPA's conclusions about the toxicity and effects of D-mannose 
are presented in this unit.
    D-mannose is a naturally occurring simple sugar (molecular formula 
C6H12O6) and is a normal constituent 
of the human diet. It is found as the free sugar in peaches, apples, 
and oranges. D-mannose occurs in the tissues of the heart, spleen, 
lung, kidney, brain, muscle, liver, and intestine of humans and other 
mammalian species as well as being present in circulating blood of 
humans at concentrations of around 1 mg/dl.
    Moreover, D-mannose is an important component of various human 
metabolic processes. When present in the human body, D-mannose is 
involved in an extensive series of metabolic transformations being 
ultimately incorporated into glycoproteins and glycolipids or formed 
into the sugar fucose which is then incorporated in glycoproteins. The 
resultant glycoproteins and glycolipids are essential to the 
maintenance of cellular integrity and to cell generation.
    D-mannose is a six carbon simple sugar (hexose) that is an epimer 
of D-glucose, having the same chemical structure but differing only in 
the three dimensional orientation of one hydroxyl group. All hexoses, 
including D-glucose and D-mannose, play significant roles in human 
metabolism, including cellular respiration and energy production. Based 
on the essentiality of these substances and the efficient modes of 
metabolism, there are no concerns for toxicity at normal dietary 
levels.

B. Toxicological Points of Departure/Levels of Concern

    D-mannose is a naturally occurring simple sugar and is a normal 
constituent of the human body. No toxicological endpoint of concern has 
been identified.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to D-mannose, EPA considered likely exposure from the use of 
D-mannose as an inert ingredient in pesticides applied to growing 
crops. Since no toxicological endpoint of concern has been identified 
and since the metabolic processes involving D-mannose are well 
understood, the Agency has determined that a quantitative dietary 
exposure assessment is not necessary. While dietary exposure may result 
from the use of D-mannose as an inert ingredient in pesticide 
formulations applied to growing crops, the amount of D-mannose 
contained in pesticide formulations and applied to growing crops would 
be at levels far below its natural occurance in foods and endogenous 
production in the human body.
    2. Dietary exposure from drinking water. Dietary exposure from 
drinking water to D-mannose can occur by drinking water that has been 
contaminated by run-off from a pesticide treated area. Since an 
endpoint for risk assessment was not identified, a quantitative dietary 
exposure assessment from drinking water for D-mannose was not 
conducted.
    3. From non-dietary exposure. The term ``residential exposure'' is 
used in this document to refer to non-occupational, non-dietary 
exposure (e.g., textiles (clothing and diapers), carpets, swimming 
pools, and hard surface disinfection on walls, floors, tables). There 
are no pesticide products containing D-mannose 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 D-mannose to share a common mechanism of toxicity 
with any other substances, and D-mannose does not appear to produce a 
toxic metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has assumed that D-mannose 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

    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.
    Because of the non-toxic nature of D-mannose, there are no 
threshold effects, which would trigger the application of section 
408(b)(2)(C).

E. Aggregate Risks and Determination of Safety

    Taking into consideration all available information on D-mannose, 
EPA has determined that there is a reasonable certainty that no harm to 
any population subgroup, including infants and children, will result 
from aggregate exposure to D-mannose under reasonable foreseeable 
circumstances. Therefore, the establishment of an exemption from 
tolerance under 40 CFR 180.920 for residues of D-mannose when used as 
an inert ingredient (sequestrant, binder, or filler) in pesticide 
formulations applied preharvest to growing crops is safe under FFDCA 
section 408.

V. Analytical Enforcement Methodology

    An analytical method is not required for enforcement purposes since 
the Agency is not establishing a numerical level limiting the amount of 
residues that cannot be exceeded.

VI. Conclusions

    Therefore, an exemption from the requirement of a tolerance is 
established under 40 CFR 180.920 for D-mannose (CAS Reg. No. 3458-28-4) 
when used as

[[Page 7404]]

an inert ingredient (sequestrant, binder, or filler) in pesticide 
formulations applied preharvest to growing crops.

VII. Statutory and Executive Order Reviews

    This final rule establishes an exemption from the requirement of a 
tolerance 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 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.
    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) (2 U.S.C. 1501 et seq.).
    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) (15 U.S.C. 272 note).

VIII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
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 
the rule in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).
