FD&C Red No. 40; 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 FD&C Red No. 40 when used as an inert 
ingredient as colorant in antimicrobial pesticide formulation in food-
contact surface sanitizer products at a maximum level in the end-use 
concentration of 20 parts per million (ppm). Diversey Inc., 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 FD&C Red No. 40.

DATES: This regulation is effective November 7, 2014. Objections and 
requests for hearings must be received on or before January 6, 2015, 
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 August 22, 2012 (77 FR 50664) (FRL-9358-
9), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 
346a, announcing the filing of a pesticide petition (PP 1E7843) by 
Diversey Inc., 8310 16th Street, Sturtevant, Wisconsin 53177. The 
petition requested that 40 CFR 180.940(a) be amended by establishing an 
exemption from the requirement of a tolerance for residues of FD&C Red 
No. 40 (CAS No. 25956-17-6) when used as an inert ingredient (colorant) 
in food-contact surface sanitizing solutions at a maximum level in the 
end-use concentration of 20 parts per million (ppm). That document 
referenced a summary of the petition prepared by Diversey Inc., the 
petitioner, which is available in the docket, EPA-HQ-OPP-2012-0572, at 
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 

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 FD&C Red No. 40 including 
exposure resulting from the exemption established by this action. EPA's 
assessment of exposures and risks associated with FD&C Red No. 40 is 
detailed in a May 9, 2014 Memorandum entitled ``Decision Document for 
Petition Number 1E7843: FD&C Red No. 40 (CAS Reg. No. 25956-17-6); 
Human Health Risk Assessment and Ecological Effects Assessment for 
Proposed Exemption from the Requirement of a Tolerance When Used as an 
Inert Ingredient in Pesticide Formulations'' which is available in the 
docket for this rule, EPA-HQ-OPP-2012-0572. A summary of that 
assessment 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 is discussed in 
this unit.
    The European Food Safety Authority (EFSA) has conducted the most 
recent (2009) full review of the toxicology of FD&C Red No. 40. This 
document relied heavily on the earlier reviews (1980), conducted by the 
Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the 
European Union Scientific Committee for Food (SCF) in 1984 and 1989. 
These evaluations of FD&C Red No. 40 included reviews of an extensive 
set of toxicological data including genotoxicity, chronic toxicity, 
carcinogenicity, reproductive and developmental toxicity and 
metabolism. The available data demonstrated that no adverse effects 
were seen in studies at limit dose levels.
    Briefly, no compound related clinical signs of toxicity were 
observed when FD&C Red No. 40 (Allura Red AC) was

[[Page 66310]]

given to rats by gavage at doses varying from 215 to 10,000 milligrams/
kilogram (mg/kg). It was not irritating to the skin of rabbits. 
Repeated dose toxicity studies were conducted in rats, dogs and pigs. 
No evidence of systemic toxicity was observed in rats fed FD&C Red No. 
40 in the diet for six weeks at doses up to 2,595 mg/kg/day. The dog 
studies (two) were determined to be too limited to derive a NOAEL. No 
compound related effects were reported in pigs given gavage dose of 
1,000 mg/kg/day for 21 days and then increased to 1,500 mg/kg/day for 
an additional 54 days.
    In chronic studies, no dye-related anomalies were noted in terms of 
survival, or gross and histopathology of major organs and the skin in 
mice treated dermally with FD&C Red No. 40 with a 5% test solution 
twice weekly for 20 months. A moderate growth depression was observed 
in both sexes of rat fed at the highest dose level of 2,595 mg/kg/day 
for 92 weeks. No compound-related effects were observed regarding 
appearance, behavior, survival, organ weights, clinical laboratory 
studies, or gross and histopathology in rats.
    FD&C Red No. 40 was evaluated for its mutagenic activity in 
adequate range of in vivo and in vitro mutagenicity assays. Overall, it 
gave a negative response for mutagenicity in in vivo and in vitro 
assays except Comet assay. EFSA Panel considered this finding in the 
light of negative carcinogenicity studies, and determined that the 
biological significance of the Comet assay results is uncertain.
    As summarized by EFSA, no evidence of carcinogenicity was observed 
in male rats at doses up to 2,595 mg/kg/day and 2,829 mg/kg/day in 
female rats; and in mice at dose levels up to 7,422 mg/kg/day in males 
and 8,304 mg/kg/day in females.
    Relevant reproductive and developmental toxicity studies are 
summarized in the EFSA document. In a multi-generation reproduction 
study in rats at a dietary levels of 0, 0.37, 0.72, 1.39 or 5.19% 
(equivalent to 0, 185, 360, 695 and 2,595 mg/kg bw/day), no treatment 
related adverse effects were observed in the parental animals. Only 
slight growth retardation was observed at the high dose levels in 
F1 and F2 pups. The NOAEL for offspring toxicity 
was 695 mg/kg/day and the LOAEL was 2,595 mg/kg/day. No reproductive or 
developmental toxicity was seen at high doses in three chronic studies 
in rats and mice in which these parameters were evaluated concurrently. 
Rats (group number not reported) were exposed up to 10% of FD&C Red No. 
40 in the diet (calculated doses of 0, 1,250, 2,500 and 5,000 mg/kg/
day). Litter mortality was increased between 22-24 days of age at a 
concentration of 10% in the diet. Significantly decreased running wheel 
activity was observed in all exposed groups. Increased open-field 
rearing was observed in the two highest dose groups. The LOAEL was 
determined to be 1,250 mg/kg/day; a NOAEL could not be determined from 
this study. No neurobehavioral effects were observed in mice 
administered 1.68% FD&C Red No. 40 via diet (equivalent to 2,400 mg/kg/
day) for 2-generations. Teratology studies in rats and rabbits showed 
no evidence of adverse effects at doses up to 200 mg/kg/day 
administered via gavage during gestation days (GD) 0-19 in rats, and at 
doses up to 700 mg/kg/day administered via gavage during GD 6-18 in 
rabbits. In rats (group number not reported) dosed with FD&C Red No. 40 
up to 0.7% in drinking water (equivalent to 939 mg/kg bw/day) during 
GDs, on GD 0-20 a significant increase in the incidence of fetuses with 
reduced ossification of the hyoid was observed at the highest dose 
level. No other fetal malformations were observed. The NOAEL from this 
study was determined to be 546 mg/kg/day.
    In rats fed 5.19% FD&C Red No. 40 in the diet, only 0.1% and 29% of 
the unmetabolized dye was found to be excreted in the urine and feces, 
respectively. Several metabolites, possibly resulting from azo-
reduction in the gastrointestinal tract (two identified as aromatic 
amines, p-cresidine sulfnic acid being the major one), were also found 
in the feces and urine. Finally, significant retention in the washed 
intestines of rat was observed, probably due to adhesion to the 
intestinal wall.

B. Toxicological Points of Departure/Levels of Concern

    Based on the low potential hazard, toxicological endpoints of 
concern have not been identified for FD&C Red No. 40. Thus, due to its 
low potential hazard and lack of 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. JEFCA and EFSA established the acceptable 
daily intake (ADI) of 0-7 mg/kg/day based on the NOAEL of 695 mg/kg/day 
derived from a reproductive toxicity study in rats, which revealed 
slight growth suppression observed mainly at the high test levels of 
2,595 mg/kg/day in F1 and F2 pups and from a 
teratogenicity study in rats which revealed lower body weights and 
growth rates at the highest dose level of 2,595 mg/kg/day but not at 
695 mg/kg bw/day. Since adverse effects in these two studies were 
observed at 2.5 times the limit dose of 1,000 mg/kg/day; EPA concluded 
that it is not warranted to conduct a quantitative risk assessment.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses and drinking water. 
Dietary exposure (food and drinking water) to FD&C Red No. 40 can occur 
following ingestion of foods with residues from food-contact surface 
sanitizing solutions for public eating places, treated dairy- and food-
processing equipment and utensils; pre- and post-harvest crop uses and 
as a direct food additives. In addition, dietary exposures to FD&C Red 
No. 40 can occur as a result of its use as a color additive in foods. 
However, EPA did not conduct a quantitative dietary exposure assessment 
since no endpoint of concern for risk assessment has been identified.
    2. 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).
    FD&C Red No. 40 is used as an inert ingredient in agricultural 
pesticide products that could result in short- and intermediate-term 
residential exposure. Residential exposure can occur via dermal and 
inhalation routes of exposure to residential applicator. Dermal and 
inhalation exposure can occur from the use of consumer products and 
foods/food additives containing FD&C Red No. 40. Since an endpoint for 
risk assessment was not identified, a quantitative residential exposure 
assessment for FD&C Red No. 40 was not conducted.
    3. 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 FD&C Red No. 40 to share a common mechanism of 
toxicity with any other substances, and FD&C Red No. 40 does not appear 
to produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that FD&C 
Red No. 40 does not have a common mechanism of toxicity

[[Page 66311]]

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 FQPA Safety 
Factor (SF). In applying this 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 
    At this time, there is no concern for potential sensitivity to 
infants and children resulting from exposures to FD&C Red No. 40. There 
is no reported quantitative or qualitative evidence of increased 
susceptibility of rat fetuses to in utero exposure to FD&C Red No. 40 
in developmental toxicity studies in rats. No quantitative or 
qualitative evidence of increased susceptibility has been reported 
following the pre/postnatal exposure to rats in 2-generation 
reproduction toxicity studies in rats. Given the lack of adverse 
toxicological effects at limit dose levels, a safety factor analysis 
has not been used to assess the risk. For these reasons the additional 
tenfold safety factor is unnecessary.

E. Aggregate Risks and Determination of Safety

    In examining aggregate exposure, EPA takes into account the 
available and reliable information concerning exposures to pesticide 
residues in food and drinking water, and non-occupational pesticide 
exposures. Dietary (food and drinking water) and non-dietary 
(residential) exposures of concern are not anticipated for FD&C Red No. 
40 because of its low toxicity based on animal studies showing toxicity 
at or above the limit dose of 1,000 mg/kg/day. Taking into 
consideration all available information on FD&C Red No. 40, 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 FD&C Red No. 40 under reasonably foreseeable 
circumstances. Therefore, the establishment of an exemption from 
tolerance under 40 CFR 180.940(a) for residues of FD&C Red No. 40 when 
used as an inert ingredient (colorant) in pesticide formulations 
applied to food contact surfaces in public eating places, dairy 
processing equipment and food processing equipment and utensils up to 
20 ppm in antimicrobial pesticide formulations 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. EPA is establishing a 
limitation on the amount of FD&C Red No. 40 that may be used in 
pesticide formulations.
    The limitation will be enforced through the pesticide registration 
process under the Federal Insecticide, Fungicide, and Rodenticide Act 
(FIFRA), 7 U.S.C. 136 et seq. EPA will not register any food-contact 
surface antimicrobial pesticide for sale or distribution with 
concentrations of FD&C Red No. 40 exceeding 20 ppm in the end use 

VI. Conclusions

    Therefore, an exemption from the requirement of a tolerance is 
established under 40 CFR 180.940(a) for FD&C Red No. 40 (CAS No. 25956-
17-6) when used as an inert ingredient (colorant) in pesticide 
formulations applied to food-contact surfaces in public eating places, 
dairy-processing equipment and food-processing equipment and utensils 
up to 20 ppm in end use formulation.

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

[[Page 66312]]

publication of the rule in the Federal Register. This action is not a 
``major rule'' as defined by 5 U.S.C. 804(2).
