2-Methyl-1,3-propanediol; 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 2-methyl-1,3-propanediol (CAS Reg. No.
2163-42-0) when used as an inert ingredient component of food contact
sanitizing solutions applied to all food contact surfaces in public
eating places, dairy-processing equipment, and food-processing
equipment and utensils. Lyondell Chemical Company 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 2-methyl-1,3-propanediol.
DATES: This regulation is effective August 1, 2012. Objections and
requests for hearings must be received on or before October 1, 2012,
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. Petition for Exemption
In the Federal Register of May 2, 2012 (77 FR 25954) (FRL-9346-1),
EPA issued a notice pursuant to FFDCA section 408, 21 U.S.C. 346a,
announcing the filing of a pesticide petition (PP 1E7946) by Lyondell
Chemical Company, 1221 McKinney Street, Houston, Texas 77010. The
petition requested that 40 CFR 180.940(a) be amended by establishing an
exemption from the requirement of a tolerance for residues of 2-methyl-
1,3-propanediol (CAS Reg. No. 2163-42-0) when used as a component of
food contact sanitizing solutions applied to all food contact surfaces
in public eating places, dairy-processing equipment, and food-
processing equipment and utensils. That notice referenced a summary of
the petition prepared by Lyondell Chemical Company, 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
[[Page 45496]]
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 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 2-methyl-1,3-propanediol
including exposure resulting from the exemption established by this
action. EPA's assessment of exposures and risks associated with 2-
methyl-1,3-propanediol 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. Specific information on the studies received and the nature
of the adverse effects caused by 2-methyl-1,3-propanediol 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 August 20, 2010 (75
FR 51388) (FRL-8838-3).
B. Toxicological Points of Departure/Levels of Concern
There was no hazard identified in repeat dose toxicity and
reproductive/developmental studies with 2-methyl-1,3-propanediol at the
limit dose of 1,000 milligram/kilogram/day (mg/kg/day) to either
parental animals or their offspring. Thus, due to its low potential
hazard and lack of a hazard endpoint, the Agency has determined that a
quantitative risk assessment using safety factors applied to a point of
departure protective of an identified hazard endpoint is not
appropriate for 2-methyl-1,3-propanediol.
2-Methyl-1,3-propanediol was not mutagenic in an in vitro
chromosome aberration test, bacterial gene mutation test, and mammalian
cell gene mutation assay and based on the available information, it is
not anticipated to be carcinogenic. Specific information on the studies
received and the nature of the adverse effects caused by 2-methyl-1,3-
propanediol are discussed in the final rule published in the Federal
Register of August 20, 2010 (75 FR 51388) and can be found at http://www.regulations.gov in the document ``Decision Document for Petition
Number 2E6484; 2-methyl-1,3-propanediol [CAS Reg No. 2163-42-0],
requesting the establishment of an inert ingredient exemption from the
requirement of a tolerance'' in docket ID number EPA-HQ-OPP-2002-0185.
C. Exposure Assessment
No hazard endpoint of concern was identified for the acute and
chronic dietary assessment (food and drinking water), or for the short,
intermediate, and long term residential assessments (via all exposure
routes), therefore, acute and chronic dietary and short-, intermediate-
, and long-term residential exposure assessments were not performed.
D. 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 2-methyl-1,3-propanediol to share a common
mechanism of toxicity with any other substances, and 2-methyl-1,3-
propanediol does not appear to produce a toxic metabolite produced by
other substances. For the purposes of this tolerance action, therefore,
EPA has assumed that 2-methyl-1,3-propanediol 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.
E. Safety Factor for Infants and Children
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 Safety Factor (FQPA SF). In applying this provision, EPA either
retains the default value of 10X, or uses a different
[[Page 45497]]
additional safety factor when reliable data available to EPA support
the choice of a different factor.
The toxicity database for 2-methyl-1,3-propanediol is adequate for
FQPA assessment and the potential exposure is adequately characterized
given the low toxicity of the chemical. No hazard was identified and
there is no residual uncertainty regarding prenatal and/or postnatal
toxicity. No acute or subchronic neurotoxicity studies are available,
but there were no clinical signs of neurotoxicity or any systemic
toxicity observed in the available database at doses up to 1,000 mg/kg/
day. No developmental or reproductive effects were seen in the
available studies at doses up to and including 1,000 mg/kg/day.
Based on this information, there is no concern, at this time, for
increased sensitivity to infants and children to 2-methyl-1,3-
propanediol when used as a component of food contact sanitizing
solutions applied to all food contact surfaces and a safety factor
analysis has not been used to assess risk. For the same reason, EPA has
determined that an additional safety factor is not needed to protect
the safety of infants and children.
F. Aggregate Risks and Determination of Safety
Given the lack of concern for hazard posed by 2-methyl-1,3-
propanediol, EPA concludes that there are no dietary or aggregate
dietary/non-dietary risks of concern as a result of exposure to 2-
methyl-1,3-propnaediol in food and water or from residential exposure.
Residues of concern are not anticipated for dietary exposure (food and
drinking water) or for residential exposure from the use of 2-methyl-
1,3-propanediol as an inert ingredient in pesticide products. As
discussed in this unit, EPA expects aggregate exposure to 2-methyl-1,3-
propanediol to pose no appreciable dietary risk given that the data
show a lack of any systemic toxicity or adverse developmental/
reproductive effects at doses up to 1,000 mg/kg/day.
Taking into consideration all available information on 2-methyl-
1,3-propanediol, EPA has determined that there is a reasonable
certainty that no harm to any population subgroup will result from
aggregate exposure to 2-methyl-1,3-propanediol under reasonable
foreseeable circumstances. Therefore, the establishment of an exemption
from tolerance under 40 CFR 180.940(a) for residues of 2-methyl-1,3-
propanediol when used as a component of food contact sanitizing
solutions applied to all food contact surface in public eating places,
dairy-processing equipment, and food-processing equipment and utensils,
is safe under FFDCA section 408.
V. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
the Agency is establishing an exemption from the requirement of a
tolerance without any numerical limitation.
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 Nation 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 not established a MRL for 2-methyl-1,3-propanediol.
VI. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established under 40 CFR 180.940(a) for residues of 2-methyl-1,3-
propanediol (CAS Reg. No. 2163-42-0) when used as a component of food
contact sanitizing solutions applied to all food contact surfaces in
public eating places, dairy-processing equipment, and food-processing
equipment and utensils.
VII. Statutory and Executive Order Reviews
This final rule establishes 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 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).
VIII. 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
[[Page 45498]]
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).
