II. Background

In the Federal Register of April 12, 2000 (65 FR 19759) (FRL-6498-8), EPA issued a notice pursuant to section 408 for the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a, as amended by the Food Quality Protection Act (FQPA) (Public Law 104-170) announcing the filing of a pesticide petition (PP 6E4705) by LignoTech USA, Inc., 100 Highway 51 South, Rothschild, WI 54474-1198. This notice included a summary of the petition prepared by the petitioner LignoTech USA, Inc. This petition requested that 40 CFR 180.1001(c) and (e) be amended by establishing an exemption from the requirement of a tolerance for residues of humic acid, sodium salt. Subsequently, the petitioner revised the petition to request the establishment of an exemption from the requirement of a tolerance for residues of humic acid, sodium salt under 40 CFR 180.1001(c) only. There were no comments received in response to the Notice of Filing. In the Federal Register of July 18, 2000 (65 FR 44469) (FRL-6595-9), the Agency established an exemption from the requirement of a tolerance for residues of humic acid, sodium salt when used as an inert ingredient (adjuvant, UV protectant) in pesticide formulations applied to growing crops and raw agricultural commodities after harvest.

In the Federal Register of March 6, 2002 (67 FR 10203) (FRL-6825-9), the Agency published a Notice of Filing to amend the above pesticide petition 6E4705 from Arctech, Inc. located at 14100 Park Meadow Drive, Chantilly, VA 20151, to amend the existing exemption from the requirement of a tolerance to include residues of humic acid, potassium salt when used as an inert ingredient in pesticide formulations applied to growing crops, raw agricultural commodities (RAC) after harvest, or to animals. The notice included a summary of the petition prepared by the petitioner, Arctech, Inc. There were no comments received in response to this Notice of Filing.

III. What Action is the Agency Taking?

EPA on its own initiative, under section 408(e) of the FFDCA, 21 U.S.C. 346a, is proposing to establish an unlimited exemption from the requirement of a tolerance for residues of humic acid, sodium salt (CAS Reg. No. 68131-04-04); humic acid, potassium salt (CAS Reg. No. 68514-28-3); and humic acid (CAS Reg. No. 1415-93-6) when used as an inert ingredient in pesticide formulations that are applied to growing crops under 40 CFR 180.1001(d).

The Agency has not issued a final rule on the petition seeking the establishment of a tolerance exemption for humic acid, potassium salt, but rather is issuing this proposed rule to amend the existing tolerance exemption for humic acid, sodium salt to also include humic acid, potassium salt; and humic acid. Based on a review and evaluation of the available data, which includes a 90-day toxicity study using humic acid, the Agency believes that the tolerance exemption should also include humic acid, not just the two salts, as requested by the petitioners. The existing tolerance exemption for humic acid, sodium salt will also be shifted from 40 CFR 180.1001(c) to 40 CFR 180.1001(d). Given that the nature of the substances considered are naturally occurring materials, and ubiquitous in the environment, but essentially, a component of soil, the Agency believes that 40 CFR 180.1001(d), i.e., application to growing crops to be more appropriate. The Agency has determined that there are no existing products containing humic acid, sodium salt having post-harvest uses. Therefore, this action will not have an effect on any currently registered pesticide product.

Section 408(b)(2)(A)(i) of the FFDCA allows EPA to establish an exemption from the requirement of 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 the 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 the FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing an exemption from the requirement of 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. . . .”

Consistent with section 408(b)(2)(D) of the FFDCA, 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, consistent with section 408(b)(2) of the FFDCA, for the establishment of an exemption from the requirement of a tolerance for humate materials. EPA's assessment of exposures and risks associated with establishing the exemption from the requirement of a tolerance follows.

IV. 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 humate materials are discussed in this unit.

Humate materials or humic substances occur naturally in the environment. They are part of the environment in which we grow our food. The use of the term humus is said to have occurred when Rome was an empire. The term has also been found in 18th century writings. Humic substances are used as soil conditioners to increase the amount of organic matter in the soil; thus, increasing the workability of the soil. They are widely regarded as being beneficial to plants.

The formation of humic substances is not completely understood. It is known that humic substances arise during the decay of organic materials, which is the reason that humic substances are often associated with coal, lignite, and mudstones. There are several theories as to possible formation pathways (lignin theory, polyphenol theory, and sugar-amine condensation). Generally, humic substances can be further subdivided into three categories: humic acids, fulvic acids, and humins. Humic acid is the major extractable component. With humates being natural substances, there is some variation in composition of the various materials.

There is some confusion as to an exact definition of humic acid. According to various information, humic acids are colloids, that behave somewhat like clays. Humic acids are macromolecules that are soluble in dilute alkali. They vary from dark brown to black in color. They are amorphous, polymeric substances with molecular weights ranging from 5,000 to 50,000. The cation exchange capacity (the total amount of exchangeable cations a soil can retain) ranges from 200 to 500 milliequivalents per 100 grams of soil at pH 7. When the cation exchange sites are mostly hydrogen, then the material is referred to as humic acid. When the predominant cation is sodium, then the material is referred to as humic acid, sodium salt. Similarly, material would be referred to as humic acid, potassium salt if the predominant cation were potassium.

A. Subchronic Toxicity

The following subchronic toxicity data (National Technical Information Service (NTIS) PB92-164946) was located through an internet search using humic as search term. An abstract is located on the National Library of Medicine Specialized Information Services (NLM/SIS). According to the abstract:

Male and female Sprague-Dawley rats were administered drinking water containing humic acids either non-disinfected or following ozonation (O3) ozonation/chlorination (O32) for 90 consecutive days. Test animals drank either of two concentration of humic acids, 0.25 and 1.0 g/L total organic carbon (TOC), while controls received phosphate-buffered, distilled water. No consistent significant treatment-related effects were observed in body weight gain, organ weights, food or water consumption, or hematological and clinical chemistry parameters. No target organs were identified from the histopathological examination of the tissues. The most significant observation, an increase in liver to body weight ratio for the male animals in the 1.0 g/LO3/CL2 humic acid group, was not observed in any other group, nor was it corroborated via any biochemical measurements or histopathological analysis.

B. Mutagenicity

An abstract discussing the mutagenicity of two coal-derived humic substances (Sulcis and South Africa, Eniricerche, Italy) was located through the NLM/SIS. Their mutagenic activity on TA98 and TA100 Salmonella typhimurium strains, both in the presence or the absence of metabolic acitivation (S9) was discussed. Both compounds showed no effect on the two strains, as observed with natural humic acid.

V. Aggregate Exposures

In examining aggregate exposure, FFDCA section 408 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 indooor uses).

EPA establishes exemptions from the requirement of tolerances only in those cases where it can be demonstrated that the risks from aggregate exposure to pesticide chemical residues under reasonable 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 tolerance may be established.

A. Dietary Exposure

1. Food. Not only are humic substances abundant in nature, but they have been used in commercial agriculture for years to condition soils. Therefore, there is likely a substantial ongoing human dietary exposure to humate materials from these sources and increased dietary exposures from the use of humate materials as an inert ingredient in pesticide formulations is expected to be minimal.

2. Drinking water exposure. Humic substances occur in abundance in nature, including soils, fresh water, and oceans. Increased drinking water exposure from the use of humate materials in pesticide formulations would not be expected.

B. Other Non-Occupational Exposure

Humic substances occur in abundance in nature, including soils that are in and around the home. The potential for an increase in the existing non-dietary exposure to the general population, including infants and children, is unlikely as these pestcide formulations containing humate materials would be used in agricultural and horticultural settings.

VI. Cumulative Effects

Section 408(b)(2)(v) of FFDCA requires that, when considering whether to establish, modify or revoke a tolerance or tolerance exemption, the Agency consider “available information” concerning the cumulative effects of particular chemical's residues and “other substances that have a common mechanism of toxicity.” The Agency has not made any conclusions as to whether or not humic acid, potassium salt shares a common mechanism of toxicity with other chemicals. However, humic acid, potasssium salt is expected to be practically non-toxic to mammals. Due to the expected lack of toxicity, a cumulative risk assessment is not necessary.

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

Humic substances are present in abundance in the soil and the environment. Humic substances have been used in commercial agriculture for years to condition soils. Based on available information on these chemically related substances, the Agency believes that humic acid; humic acid, postassium salt; and humic acid, sodium salt are practically non toxic to mammals. Due to the ubiquitous nature of these naturally occurring materials, and the high molecular weights of the humic materials, no chronic or acute effects are expected to occur. There is no available information to indicate that these naturally occurring substances are carcinogenic, mutagenic, or expected to have any effect on the immune or endocrine systems. Because of its abundance in nature and lack of toxicity, the Agency did not use the safety factor analysis in evaluating the risk posed by humate substances and did not apply an additional tenfold safety factor to protect infants and children.

Based on the information in the preamble, EPA concludes that there is a reasonable certainty of no harm from aggregate exposure to residues of humic acid; humic acid, potassium salt; and humic acid, sodium salt. Accordingly, EPA finds that exempting these humate materials from the requirement of a tolerance will be safe.

IX. Other Considerations

A. Endocrine Disruptors

FQPA requires EPA to develop a screening program to determine whether certain substances, including all pesticide chemicals (both inert and active ingredients), “may have an effect in humans that is similar to an effect produced by a naturally occuring estrogen, or such other endocrine effect....” EPA has been working with interested stakeholders to develop a screening and testing program as well as a priority setting scheme. As the Agency proceeds with implementation of this program, further testing of products containing humic acid, potassium salt for endocrine effects may be required.

B. Analytical Method(s)

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.

C. Existing Exemptions

An exemption from the requirement of a tolerance does exist for humic acid, sodium salt (40 CFR 180.1001(c)) for use as an adjuvant, UV protectant.

D. International Tolerances

The Agency is not aware of any country requiring a tolerance for humic substances nor have any CODEX Maximum Residue Levels (MRLs) been established for any food crops at this time.

X. Conclusions

Based on the information in this preamble, EPA concludes that there is a reasonable certainty of no harm from aggregate exposure to residues of humic acid; humic acid, potassium salt; and humic acid, sodium salt. Accordingly, EPA finds that exempting humate materials from the requirement of a tolerance will be safe.

XI. Statutory and Executive Order Reviews

This proposed rule establishes a consolidated and expanded exemption from the requirement for a tolerance under section 408(d) of the FFDCA. 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 proposed rule has been exempted from review under Executive Order 12866 due to its lack of significance, this proposed rule is not subject to Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001). This proposed 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) (Public Law 104-4). 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); or OMB review or any Agency action under Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997). 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). The Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.) generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule will not have a significant impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental organizations. After considering the economic impacts of today's proposed rule on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. Establishing an exemption from the requirement of a pesticide tolerance (or, expanding and consolidating a tolerance exemption, as is proposed today), is in effect, the removal of a regulatory restriction on pesticide residues in food and thus such an action will not have any negative economic impact on any entities, including small entities. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.” This proposed rule directly regulates growers, food processors, food handlers and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of the FFDCA. For these same reasons, the Agency has determined that this proposed rule does not have any “tribal implications” as described in Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 6, 2000). Executive Order 13175, requires EPA to develop an accountable process to ensure “meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.” “Policies that have tribal implications” is defined in the Executive Order to include regulations that have “substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and the Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.” This proposed rule will not have substantial direct effects on tribal governments, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this proposed rule.
