02-22369. Lactic acid, ethyl ester and Lactic acid, n-butyl ester; Exemptions from the Requirement of a Tolerance

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

This regulation establishes two exemptions from the requirement of a tolerance for residues of lactic acid, ethyl ester and lactic acid, n-butyl ester when used in pesticide formulations. PURAC America, Inc. submitted two petitions to EPA under the Federal Food, Drug, and Cosmetic Act, as amended by the Food Quality Protection Act of 1996, requesting these exemptions from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of lactic acid, ethyl ester and lactic acid, n-butyl ester.

DATES:

This regulation is effective September 3, 2002. Objections and requests for hearings, identified by docket ID number OPP-2002-0217, must be received on or before November 4, 2002.

ADDRESSES:

Written objections and hearing requests may be submitted by mail, in person, or by courier. Please follow the detailed instructions for each method as provided in Unit VIII. of the SUPPLEMENTARY INFORMATION. To ensure proper receipt by EPA, your objections and hearing requests must identify docket ID number OPP-2002-0217 in the subject line on the first page of your response.

II. Background and Statutory Findings

In the Federal Register of April 12, 2000 (65 FR 19759) (FRL-6498-8), EPA issued a notice pursuant to section 408 of 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 pesticide tolerance petitions (PP 5E4510 and 5E4515) by PURAC America, Inc., Barclay Boulevard, Lincolnshire Corporate Center, Lincolnshire, IL 60069. This notice included a summary of the petitions prepared by the petitioner PURAC. There were no comments received in response to the notice of filing.

The petitions requested that 40 CFR 180.1001(c) and (e) be amended by establishing an exemption from the requirement of a tolerance for residues of ethyl lactate (CAS Reg. No. 97-64-3), also known as lactic acid, ethyl ester, and butyl lactate (CAS Reg. No. 138-22-7), also known as lactic acid, n-butyl ester.

Section 408(b)(2)(A)(i) of the 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) 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) 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 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. Human Health Assessment

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. The nature of the toxic effects caused by lactic acid, ethyl ester and lactic acid, n-butyl ester are discussed in this unit.

A. Toxicological Profile (Agency-Reviewed Studies) for Lactic Acid, Ethyl Ester (Ethyl Lactate)

1. Acute oral toxicity in the rat. Groups of five young adult outbred rats/sex were given a single oral dose of 2,000 milligrams/kilogram (mg/kg). All animals survived the 14-day observation period. No significant treatment-related effects on body weight were observed during the study, and gross necropsies of animals sacrificed after 14 days revealed no observable abnormalities. The lethal dose (LD₅₀) is greater than 2,000 mg/kg (males; females).

2. Dermal developmental toxicity in the rat. Lactic acid, ethyl ester was administered percutaneously to 25 rats/dose at dose levels of 0 (sham), 517, 1,551, or 3,619 mg/kg/day for 6 hours/day on days 6-15 of gestation. No systemic toxicity was noted at any dose level. Body weights, body weight gains, feed consumption, mortality, clinical signs of toxicity, and cesarean section parameters were unaffected by treatment. There were no treatment-related effects found on caesarean section examinations of the dams or external, visceral, or skeletal examinations of the fetuses. Both the maternal and developmental no observed adverse effect level (NOAEL) was 3,619 mg/kg/day, the highest dose tested. The lowest observed adverse effect level (LOAEL) was not determined, but would be greater than 3,619 mg/kg/day.

3. Inhalation studies. Three inhalation studies using lactic acid, ethyl ester were also submitted. However, the Agency was not able to use this information since the aerodynamic particle sizes (the mass median aerodynamic diameter (MMAD) and distribution of measurements) and the time required to reach equilibrium of the generated aerosols were not provided.

B. Toxicological Profile (Agency-Reviewed Studies) for Lactic Acid, n-Butyl Ester (Butyl Lactate)

1. Acute oral toxicity in the rat. Groups of five young adult outbred rats/sex were given a single oral dose of 2,000 mg/kg. All animals survived the 14-day observation period. No treatment-related effect on body weight was observed during the study and gross necropsies of animals sacrificed after 14 days revealed no observable abnormalities. The LD₅₀ is greater than 2,000 mg/kg (males; females)

2. Acute inhalation toxicity in the rat. Groups of five young adult outbred rats/sex were given a whole body exposure to n-butyl-S-(-)- lactate vapor at 5.14 milligrams/liter (mg/L) (greater than 2X limit concentration) for 4 hours. All animals survived the 4-hour exposure period and 14-day observation periods. Moderately decreased breathing frequencies, wet fur (nose/head), were observed in 10/10 animals during and just following exposure. Effects subsided from all animals by day 1. No treatment-related effects on body weight were observed during the study, and gross necropsy after 14 days revealed no abnormalities. The lethal concentration (LC₅₀) is greater than 5.14 mg/L.

C. Structure Activity Relationship Assessment

For lactic acid, ethyl ester and lactic acid, n-butyl ester], toxicity was assessed, in part, by a process called structure-activity relationship (SAR). In this process, the chemical's structural similarity to other chemicals (for which data are available) is used to determine toxicity. For human health, this process, can be used to assess absorption and metabolism, mutagenicity, carcinogenicity, developmental and reproductive effects, neurotoxicity, systemic effects, immunotoxicity, and sensitization and irritation. This is a qualitative assessment using terms such as good, not likely, poor, moderate, or high.

For lactic acid, ethyl ester and lactic acid, n-butyl ester the SAR assessment determined that the chemical was not structurally related to any known carcinogens or developmental/reproductive toxicants. The following human exposures were examined as part of the analysis: inhalation, dermal, exposures to the eyes, and drinking water. For both chemicals, absorption is expected to be good (well-absorbed) for all routes based on analog data. It was noted that ester hydrolysis would be expected to release the corresponding alcohol. Both chemicals would be expected to be irritating to mucous membranes, and there is the possibility of irritation to the lungs and eyes. For both lactic acid, ethyl ester and lactic acid, n-butyl ester, the overall rating for human health is low concern.

The SAR did note a concern for solvent neurotoxicity, i.e., neurotoxic effects that can occur due to high and/or prolonged dermal and inhalation exposures to organic solvents. According to the SAR, the greatest concerns for both ethyl and butyl lactate, based on their structural chemistry and chemical class, are concerns for possible solvent neurotoxicity and irritation to mucous membranes, lungs and eyes. It should be noted that the inclusion of the phrase concerns for solvent-type neurotoxicity in the SAR assessment does not necessarily indicate chemical-specific concerns. By including this statement those performing the assessment are acknowledging that the chemical is a member of a class of chemicals that can exhibit solvent neurotoxicity.

D. Findings of the FAO/WHO Expert Committee on Food Additives

Ethyl lactate has been examined at several meetings of the (United Nations Food and Agriculture Organization/World Health Organization) FAO/WHO Joint Expert Committee on Food Additives (JECFA). At the last meeting, the absorption and metabolism of ethyl lactate was extensively studied. There has long been evidence that in mammals simple esters such as ethyl lactate readily undergo hydrolysis, yielding the alcohol and acid from which the ester was formed. In the case of ethyl lactate, this would be ethyl alcohol (ethanol) and lactic acid. The human metabolism of ethanol is well understood: it is oxidized to carbon dioxide and water. The metabolism of lactic acid is also understood: it is an intermediate in human metabolism of glucose. The Committee determined that recent in vivo and in vitro studies indicated that ethyl-L-lactate was hydrolysed to ethyl alcohol and lactic acid mainly prior to absorption. Based on this understanding of the metabolism of ethyl lactate, the Committee also determined that it was not necessary to specify an estimate of acceptable daily intake.

E. Conclusions

The SAR assessments did not identify any concerns for carcinogenicity or developmental toxicity for either of these lactate esters. In fact, both lactic acid, ethyl ester and lactic acid, n-butyl ester were judged to be of low concern. The only concerns identified were for possible solvent neurotoxicity and irritation to mucous membranes, lungs and eyes. These identified concerns are for the dermal and inhalation exposure routes and are addressed through the use of protective equipment such as gloves and respirators, not through establishment of tolerance exemptions.

The lactic acid, ethyl ester dermal developmental toxicity study indicates low toxicity to both the mother and the developing fetus. Both the developmental and maternal NOAELs (3,619 mg/kg/day) are the highest dose tested. Given the structural similarities of the two chemicals, the Agency believes that the developmental toxicity study can be bridged to lactic acid, n-butyl ester.

The JECFA monograph deemed lactic acid, ethyl ester to be of such low concern that the acceptable daily intake is not specified. A consideration in this decision was the understanding that hydrolysis would occur in the human body thus yielding ethanol and lactic acid. The same hydrolysis would occur for lactic acid, n-butyl ester but would yield butanol and lactic acid. Butanol is also metabolized in the human body butanol is oxidized to butyraldehyde, which is oxidized to butyric acid, which is then metabolized via the fatty acid and tricarboxylic acid pathways. Thus, the human body has a known pathway to metabolize lactic acid, ethyl ester and lactic acid, n-butyl ester, and their metabolites.

IV. 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 indoor uses).

For lactic acid, ethyl ester and lactic acid, n-butyl ester a qualitative assessment for all pathways of human exposure (food, drinking water, and residential) is appropriate given the SARs which judged lactic acid, ethyl ester and lactic acid, n-butyl ester to be of low concern and the body's ability to metabolize lactic acid, ethyl ester and lactic acid, n-butyl ester, and their metabolites.

V. Cumulative Effects

Section 408(b)(2)(D)(v) 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. Lactic acid, ethyl ester and lactic acid, n-butyl ester are structurally related; however, both are lower toxicity chemicals; therefore, the resultant risks separately and/or combined should also be low. EPA does not have, at this time, available data to determine whether lactic acid, ethyl ester and lactic acid, n-butyl ester have a common mechanism of toxicity with other substances or how to include these pesticide chemicals in a cumulative risk assessment.

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

Based on the available date, the SAR assessment indicating low concern, and information on the metabolism of lactic acid, ethyl ester and lactic acid, n-butyl ester, EPA concludes that lactic acid, ethyl ester and lactic acid, n-butyl ester do not pose a dietary risk under reasonably foreseeable circumstances. Accordingly, EPA finds that there is a reasonable certainty that no harm will result to the general population, and to infants and children from aggregate exposure to lactic acid, ethyl ester and lactic acid, n-butyl ester. For both lactic acid, ethyl ester and lactic acid, n-butyl ester, due to the expected low oral toxicity, a safety factor analysis has not been used to assess the risk. For the same reasons and especially considering the developmental toxicity NOAEL, the additional tenfold safety factor for the protection of infants and children is unnecessary.

VII. 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 occurring 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 lactic acid, ethyl ester and lactic acid, n-butyl ester 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 Tolerances

There are no existing tolerances or tolerance exemptions for ethyl and butyl lactate.

D. International Tolerances

The Agency is not aware of any country requiring a tolerance for lactic acid, ethyl ester and lactic acid, n-butyl ester nor have any CODEX Maximum Residue Levels (MRLs) been established for any food crops at this time.

E. List 4A Classification

It has been determined that lactic acid, ethyl ester and lactic acid, n-butyl ester are to be classified as List 4A inert ingredients. Thus, the tolerance exemptions will be established in 40 CFR 180.950 instead of 40 CFR 180.1001(c) and (e) as requested by the petitioner PURAC.

VIII. Conclusions

Based on the information in the record, summarized in this preamble, EPA concludes that there is a reasonable certainty of no harm from aggregate exposure to residues of lactic acid, ethyl ester and lactic acid, n-butyl ester. Accordingly, EPA finds that exempting lactic acid, ethyl ester and lactic acid, n-butyl ester from the requirement of a tolerance will be safe.

IX. Objections and Hearing Requests

Under section 408(g) of the FFDCA, as amended by the FQPA, any person may file an objection to any aspect of this regulation and may also request a hearing on those objections. The EPA procedural regulations which govern the submission of objections and requests for hearings appear in 40 CFR part 178. Although the procedures in those regulations require some modification to reflect the amendments made to the FFDCA by the FQPA of 1996, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) provides essentially the same process for persons to “object ” to a regulation for an exemption from the requirement of a tolerance issued by EPA under new section 408(d), as was provided in the old FFDCA sections 408 and 409. However, the period for filing objections is now 60 days, rather than 30 days.

B. When Will the Agency Grant a Request for a Hearing?

A request for a hearing will be granted if the Administrator determines that the material submitted shows the following: There is a genuine and substantial issue of fact; there is a reasonable possibility that available evidence identified by the requestor would, if established resolve one or more of such issues in favor of the requestor, taking into account uncontested claims or facts to the contrary; and resolution of the factual issues(s) in the manner sought by the requestor would be adequate to justify the action requested (40 CFR 178.32).

X. Regulatory Assessment Requirements

This final rule establishes an exemption from the tolerance requirement 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 rule has been exempted from review under Executive Order 12866 due to its lack of significance, this 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 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., 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). 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. 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 final 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 FFDCA section 408(n)(4). For these same reasons, the Agency has determined that this 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 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 rule.

XI. Submission to Congress and the Comptroller General

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, 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).
