2011-7465. Sodium Ferric Ethylenediaminetetraacetate; 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 sodium ferric ethylenediaminetetraacetate (EDTA) in or on all food commodities when applied as a molluscicide and used in accordance with good agricultural practices. W. Neudorff GmbH KG submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of sodium ferric EDTA under the FFDCA.

DATES:

This regulation is effective March 30, 2011. Objections and requests for hearings must be received on or before May 31, 2011, 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 September 30, 2010 (75 FR 60452) (FRL-8837-2), 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 tolerance petition (PP 9F7668) by W. Neudorff GmbH KG, An der Mühle 3, Postfach 1209, 31860 Emmerthal, Germany (c/o Walter G. Talarek, P.C., 1008 Riva Ridge Dr., Great Falls, VA 22066-1620). The petition requested that 40 CFR part 180 be amended by establishing an exemption from the requirement of a tolerance for residues of sodium ferric EDTA. This notice referenced a summary of the petition prepared by the petitioner, W. Neudorff GmbH KG, which is available in the docket, http://www.regulations.gov. There were no comments received in response to the notice of filing.

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 exemption is “safe.” Section 408(c)(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. Pursuant to section 408(c)(2)(B) of FFDCA, in establishing or maintaining in effect an exemption from the requirement of a tolerance, EPA must take into account the factors set forth in section 408(b)(2)(C) of FFDCA, which require 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.” Additionally, section 408(b)(2)(D) of FFDCA requires that 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 performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. First, EPA determines the toxicity of pesticides. Second, EPA examines exposure to the pesticide through food, drinking water, and through other exposures that occur as a result of pesticide use in residential settings.

III. Toxicological Profile

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 and considered its validity, completeness, and reliability and the relationship of this information 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.

A. Overview of Sodium Ferric EDTA

The pesticidal active ingredient, sodium ferric EDTA, is a molluscicide that has historically been used to control terrestrial slugs and snails in agriculture and on ornamental landscaping. The compound is comprised of iron in a sodium chelate. This chelate forms a soluble, complex molecule with iron ions, inactivating the ions so that they cannot normally react with other elements or ions to produce precipitates or scale. In this form, the iron is more bioavailable than in other mineral sources (Ref. 1). Bioavailability of iron is an essential quality of sodium ferric EDTA as the iron in this compound is responsible for controlling slugs and snails. That is, when slugs or snails ingest sodium ferric EDTA, the iron in the compound interacts with hemocyanin, a copper-based respiratory protein common to the blood of mollusks and responsible for their oxygen transport. This interaction with hemocyanin causes suffocation and eventually results in the death of slugs and snails. Iron does not have this interaction, however, in organisms that do not use hemocyanin for oxygen transport (e.g., mammals).

Iron is a necessary nutrient for all mammals and other vertebrates because it is a component of hemoglobin, the oxygen transport protein found in red blood cells of vertebrates. It is the most abundant element on Earth and, as such, can be found in most soil and water. It is an essential nutrient listed as Generally Recognized as Safe (GRAS) by the Food and Drug Administration (FDA) for direct addition to food (21 CFR 184.1375) and is added to commonly consumed, fortified foods such as enriched flour, bread, pasta, and grains. Sodium Ferric EDTA is allowed as a direct food additive by the FDA and is used as a source of iron for nutritional fortification in foods such as powdered meal replacements, flavored milk, and fruit-flavored beverages (Ref. 2), as well as soy, fish, teriyaki, and hoisin sauces (Ref. 3). The compound is also a common constituent of many cosmetic products and, despite being present at much higher concentrations than those found in sodium ferric EDTA end-use pesticide products used for control of slugs and snails, has an extensive history of safe use as an agricultural fertilizer.

In 2008, EPA registered the first sodium ferric EDTA-containing product for control of slugs and snails. EPA assessed the risks to human health and concluded that, when sodium ferric EDTA was used in accordance with widespread and commonly recognized practices, no unreasonable adverse effects on the environment were expected (Ref. 4). At the time of this initial sodium ferric EDTA registration, the applicant did not petition EPA to establish a tolerance or tolerance exemption because all uses were non-food. On December 6, 2009, however, EPA was petitioned by W. Neudorff GmbH KG to establish an exemption from the requirement of a tolerance for residues of sodium ferric EDTA in or on all food commodities. Accordingly, EPA has completed a risk assessment of mammalian toxicology data submitted in support of this request. The overall conclusions from these data are described in Unit III.B., while more in-depth synopses of the study results can be found in the risk assessment and Biopesticides Registration Action Document provided as references in Unit IX. (Refs. 5 and 6).

B. Biochemical Pesticide Human Health Assessment Data Requirements

1. Acute toxicity. Tier I acute toxicity studies of technical grade sodium ferric EDTA (Slugkil MP, containing 71.42% sodium ferric EDTA) showed that the active ingredient is a Toxicity Category III (slightly toxic) compound via the oral and dermal routes of exposure, a Toxicity Category III (slightly irritating) compound via the dermal and eye routes of exposure, and a Toxicity Category IV (practically nontoxic) compound for inhalation exposure. Moreover, sodium ferric EDTA is not a dermal sensitizer. Given the results of these studies, no additional toxicity (i.e., Tiers II or III) or residue data are required to support food uses of this biochemical active ingredient. These acute toxicity studies confirm sodium ferric EDTA's low toxicity profile.

i. The acute oral median lethal dose (LD₅₀) for sodium ferric EDTA in rats was greater than 2,000 milligrams per kilogram (mg/kg) and confirmed low toxicity through oral exposure (Master Record Identification Number (MRID No.) 47942507). Sodium Ferric EDTA is classified as Toxicity Category III for acute oral toxicity.

ii. The acute dermal LD₅₀ for sodium ferric EDTA in rats was greater than 2,000 mg/kg, which confirmed low dermal toxicity (MRID No. 47942508). Sodium Ferric EDTA is classified as Toxicity Category III for acute dermal toxicity.

iii. The acute inhalation median lethal concentration (LC₅₀) for sodium ferric EDTA in rats was greater than 2.75 milligrams per liter (mg/L) and showed practically no inhalation toxicity (MRID No. 47942512). Sodium Ferric EDTA is classified as Toxicity Category IV for acute inhalation toxicity.

iv. A primary eye irritation study showed that exposure to sodium ferric EDTA will cause temporary, mild eye irritation (MRID No. 47942509). Accordingly, EPA has determined that sodium ferric EDTA is Toxicity Category III for primary eye irritation.

v. A primary dermal irritation study showed that exposure to sodium ferric EDTA is slightly irritating (MRID No. 47942510) and a skin sensitization study showed that sodium ferric EDTA is not a sensitizer to the skin (MRID No. 47942511). Accordingly, EPA has determined that sodium ferric EDTA is Toxicity Category III for dermal irritation.

2. Subchronic toxicity.—i. Submission of 90-day oral toxicity data was waived by EPA because the acute oral toxicity study demonstrated sodium ferric EDTA's low toxicity (LD₅₀ >2,000 .mg/kg). In their waiver rationale, the petitioner also cited information from EPA's 2008 sodium ferric EDTA Biopesticides Registration Action Document (BRAD):

No references for feeding studies using sodium ferric EDTA were located in the published literature. Rats fed low mineral diets with or without calcium disodium EDTA for four months had reduced weight gain, but their general condition was comparable to that of controls (Ref. 7). Rats fed 1%, 5%, or 10% disodium salt of EDTA for 90 days had significantly lower food consumption and weight gain than controls (Ref. 8). Hematology was comparable among all groups, except that prothrombin time was increased in the 10% group. The only significant necropsy finding was pale livers in the 10% group.

Mice fed 3,750 or 7,500 ppm trisodium EDTA for 103 weeks had no treatment-related clinical signs, and gross and microscopic pathology were unremarkable (Ref. 9). A companion study conducted by NCI using rats produced the same results (Ref. 9). In a 12-month feeding study using dogs, Oser et al (1963) found no significant changes in hematology or urinalysis parameters, and no abnormal gross or microscopic findings in groups receiving up to 250 mg/kg body weight/day of calcium disodium EDTA (Ref. 10).

The information cited above refers to feeding studies using sodium EDTA and calcium disodium EDTA. The Agency has assessed the toxicity profile of these and other EDTA salts (Refs. 11 and 12), and concluded that they are closely related. This information sufficed for the assessment of toxicological risk characterization of sodium ferric EDTA.

Additionally, iron is an essential nutrient listed as GRAS by the FDA, and both iron and sodium ferric EDTA are allowed as direct food additives to increase the nutritional content of food and food supplements. Sodium Ferric EDTA is also used in agriculture as a fertilizer. Given all of this information, EPA concluded that no subchronic oral toxicity is expected when this compound is used in accordance with good agricultural practices.

ii. Submission of 90-day dermal toxicity data was waived by EPA because acute guideline studies demonstrated that sodium ferric EDTA has low dermal toxicity (LD₅₀ >2,000 mg/kg), is a slight dermal irritant, and is not a dermal sensitizer. Repeated dermal exposure, under conditions of product use at a concentration that could be toxic, is not anticipated.

iii. Submission of 90-day inhalation data was waived by EPA because the acute inhalation toxicity study demonstrated sodium ferric EDTA's lack of toxicity (Toxicity Category IV). Repeated inhalation exposure, under conditions of product use at a concentration that could be toxic, is not anticipated.

3. Developmental toxicity and mutagenicity. Acceptable waiver requests were submitted to address the data requirements for Developmental toxicity and Mutagenicity (OPPTS 870.3700). The Agency concluded that humans are regularly exposed to iron found abundantly in nature and from the use of sodium ferric EDTA as fertilizer. No negative effects of sodium ferric EDTA have been reported because of its low toxicity and low water solubility, which decreases its absorption in the intestine. Moreover, the active ingredient is not a mutagen nor is it related to any known classes of mutagens. After considering the aforementioned information and the extensive history of use of sodium ferric EDTA in agriculture and food without deleterious effects, EPA waived the requirement to submit developmental toxicity and mutagenicity data.

IV. Aggregate Exposures

In examining aggregate exposure, section 408 of FFDCA directs EPA to consider available information concerning exposures from the pesticide residue in food and all other non-occupational exposures, including drinking water from ground water or surface water and exposure through pesticide use in gardens, lawns, or buildings (residential and other indoor uses).

A. Dietary Exposure

1. Food. The primary route of sodium ferric EDTA exposure to the general population will be through consumption of food; however, there is no reason to expect that practical use of sodium ferric EDTA, in accordance with good agricultural practices, will constitute any significant hazard.

Sodium Ferric EDTA is comprised of iron in a sodium chelate. Iron is abundant in nature, an essential nutrient, and listed as GRAS for direct addition to food (21 CFR 184.1375). Sodium Ferric EDTA is regarded as safe for use as a dietary supplement to increase iron bioavailability and prevent iron deficiency. In humans, iron is an essential nutrient that is vital to the processes by which cells generate energy. It is available to animals from food derived from other animals and plants.

When sodium ferric EDTA is ingested, the chelate holds the iron in the stomach until pH rises in the upper small intestine. As pH rises, the strength of the complex progressively diminishes, allowing exchange with other metals and iron for absorption. Iron dissociates from the EDTA moiety and is released in the duodenum prior to absorption. Only a very small fraction of the sodium ferric EDTA complex (less than 1%) is absorbed intact. Intact EDTA metal complexes are rapidly excreted; they do not accumulate or undergo biotransformation (Ref. 13).

European Food Safety Authority Panel on Food Additives and Nutrient Sources added to Food (2010) concluded that, when sodium ferric EDTA is used in food supplements at levels that provide 22.3 milligrams (mg) of iron/day for adults and 11.1 mg of iron/day for children, the use of sodium ferric EDTA as a source of iron in foods is of no safety concern as long as it does not lead to an exposure of EDTA above 1.9 mg/kg/day.

Exposure to EDTA and salts of EDTA already occurs through certain FDA-approved uses as food additives, in sanitizing solutions, and in pharmaceutical products, or through their use in soaps, shampoos, or cosmetics. EDTA has also been administered safely under medical supervision as treatment for heavy metal poisoning. The results of toxicity testing and information found in public literature indicate that there is no risk to human health from residues of sodium ferric EDTA in food crops. Furthermore, residues from the formulations in agricultural use sites (certified limits <4% by weight) and residential use sites (<1% of typical formulations) are not likely to exceed levels currently consumed in commonly eaten foods. In addition, the use of EDTA and EDTA salts in pesticide products is expected to result in much lower exposure than the FDA-regulated use of these compounds, as well as lower exposure than their use in pharmaceuticals or cosmetic products.

The concentration of iron needed for good plant growth is below the concentration needed by animals for good cellular functioning. In agriculture, iron sodium chelate is used as micronutrient fertilizer at much higher concentrations than those present in sodium ferric EDTA-containing pesticide products, which are labeled for maximum application rates of below 25 mg of sodium ferric EDTA per square foot. The use of sodium ferric EDTA in pesticides is expected to result in much lower exposure than through its use in plant fertilizers, pharmaceutical products, or cosmetic products. Based on review and evaluation of available information, EPA concludes that there is a reasonable certainty of no harm from residues of sodium ferric EDTA when applied as a molluscicide and used in accordance with good agricultural practices.

2. Drinking water exposure. No significant drinking water exposure or residues are expected to result from the use of sodium ferric EDTA as a molluscicide. The active ingredient is intended for use directly on food commodities or the soil around crops and is not to be applied directly to water. If used in accordance with EPA-approved labeling and good agricultural practices, sodium ferric EDTA is not likely to accumulate in drinking water. Overall, exposures from residues in drinking water are unlikely and are not expected to pose a quantifiable risk due to environmental fate of sodium ferric EDTA and lack of residues of toxicological concerns.

B. Other Non-Occupational Exposure

The potential for non-dietary exposure of the general population, including infants and children, is limited based on the use patterns of sodium ferric EDTA. The end use products containing sodium ferric EDTA are granules or pellets that do not produce any dust and are applied directly to the ground. Therefore, it is unlikely that there will be any dermal or inhalation exposure when the product is applied according to the label use directions. Furthermore, sodium ferric EDTA was demonstrated to be practically non-toxic (Toxicity Category IV) to rats in an acute dermal toxicity guideline study (MRID 45848104) and practically non-toxic (Toxicity Category IV) to rats in an acute inhalation toxicity guideline study (MRID 45848105). Non-dietary exposures are not expected to pose any quantifiable risk to the general population.

V. 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 sodium ferric EDTA to share a common mechanism of toxicity with any other substances, and sodium ferric EDTA does not appear to produce a toxic metabolite as its mode of action against the target pests. For the purposes of this tolerance action, therefore, EPA has assumed that sodium ferric EDTA 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.

VI. Determination of Safety for U.S. Population, Infants and Children

FFDCA section 408(b)(2)(C) provides that EPA shall assess the available information about consumption patterns among infants and children, special susceptibility of infants and children to pesticide chemical residues, and the cumulative effects on infants and children of the residues and other substances with a common mechanism of toxicity. In addition, FFDCA section 408(b)(2)(C) 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 unless EPA determines that a different margin of safety will be safe for infants and children. Margins of exposure (safety), which are often referred to as uncertainty factors, are incorporated into EPA risk assessments either directly or through the use of a margin of exposure analysis, or by using uncertainty (safety) factors in calculating a dose level that poses no appreciable risk.

Based on the results of the toxicological data discussed in Unit III.B., as well as all other available information, EPA concludes that there is a reasonable certainty that no harm will result to the U.S. population, including infants and children, from aggregate exposure to the residues of sodium ferric EDTA. This includes all anticipated dietary exposures and all other exposures for which there is reliable information. EPA has arrived at this conclusion based on the low level of toxicity of the compound, the minimal exposure from application/use of sodium ferric EDTA as a molluscicide, and the already widespread exposure through use as a fertilizer and food additive without any reported adverse effects on human health. Thus, there are no threshold effects of concern and, as a result, an additional margin of safety is not necessary.

VII. 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 Nations 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 sodium ferric EDTA.

VIII. Conclusions

EPA concludes that there is a reasonable certainty that no harm will result to the U.S. population, including infants and children, from aggregate exposure to residues of sodium ferric EDTA. Therefore, an exemption is established for residues of sodium ferric EDTA in or on all food commodities when applied as a molluscicide and used in accordance with good agricultural practices.

X. 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 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 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.

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 section 408(n)(4) of FFDCA. 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).

XI. 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).
