AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

This regulation establishes exemptions from the requirement of a tolerance for residues of amylopectin, acid-hydrolyzed, 1-octenylbutanedioate (CAS Reg. No. 113894-85-2) and for amylopectin, hydrogen 1-octadecenylbutanedioate (CAS Reg. No. 125109-81-1) when used in antimicrobial formulations (food-contact surface sanitizing solutions) under 40 CFR 180.940(a), and when used in accordance with good agricultural or manufacturing practice under 40 CFR 180.950. The petitioner, Lewis & Harrison, LLC, on behalf of Alco Chemical, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA), requesting an exemption from the requirement of a tolerance. This Start Printed Page 53722regulation eliminates the need to establish a maximum permissible level for residues of amylopectin, acid-hydrolyzed, 1-octenylbutanedioate and amylopectin, hydrogen 1-octadecenylbutanedioate.

II. Background and Statutory Findings

In the Federal Register of December 20, 2006 (71 FR 76321) (FRL-8104-4), EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 346a, as amended by FQPA (Public Law 104-170), announcing the filing of a pesticide petition (PP 6E7083) by Lewis & Harrison, LLC, on behalf of Alco Chemical, 122 C St., NW., Suite 740, Washington, DC 20001. The petition requested that 40 CFR 180.940(a) and 40 CFR 180.950 be amended by establishing exemptions from the requirement of a tolerance for residues of amylopectin, acid-hydrolyzed, 1-octenylbutanedioate (CAS Reg. No. 113894-85-2) and amylopectin, hydrogen 1-octadecenylbutanedioate (CAS Reg. No. 125109-81-1) when used in antimicrobial formulations (food-contact surface sanitizing solutions) under 40 CFR 180.940(a) and when used in accordance with good agricultural or manufacturing practice under 40 CFR 180.950. That notice included a summary of the petition prepared by the petitioner. There were no comments received in response to the notice of filing. For ease of reading in this document amylopectin, acid-hydrolyzed, 1-octenylbutanedioate (CAS Reg. No. 113894-85-2) and amylopectin, hydrogen 1-octadecenylbutanedioate (CAS Reg. No. 125109-81-1) are referred to as starch octenylsuccinates.

Section 408(b)(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.” Start Printed Page 53723Section 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 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. The nature of the toxic effects caused by starch octenylsuccinates are discussed in this unit.

The following provides a brief summary of the risk assessment and conclusions for the Agency's review of starch octenylsuccinates. The Agency's full decision document for this action is available in EPA's Electronic Docket at http://www.regulations.gov, under docket number EPA-HQ-OPP-2006-0791.

The toxicity database is sufficient for starch octenylsuccinates. In terms of hazard, there are low concerns (practically non-toxic). In subchronic and chronic toxicity feeding studies in rats, the results show that the compound does not produce compound-related effects at dietary concentrations as high as 30% of the diet (equivalent to 15 gram/kilogram/day (g/kg/day)). While no neurotoxicity studies where submitted, neurotoxicity was not observed in the dietary studies at concentrations as high as 30% (15 g/day) of the test material. The compound does not suggest increased toxicity in young rats and all the mutagenicity testing results were negative. The metabolism data showed that with oral dosing in dogs,14 C-octenylsuccinate was absorbed and eliminated via the urine and feces. The major route of elimination was via urine (62-72% of the administered radioactivity). No developmental toxicity studies are available in the data base. However, in the dietary study conducted in rats fed octenylsuccinate modified starch during gestation through post-natal day 90 at doses up to 30% (15 g/day), there was no systemic toxicity in female rats and their offspring.

Furthermore, it should be noted that starch octenylsuccinate anhydride is currently permitted by the U.S. Food and Drug Administration (FDA) as a direct food additive under 21 CFR 172.892.

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).

For dietary exposures, application of starch octenylsuccinates to food (including crops, meats, and fish) as inert ingredients in pesticide products is not expected to result in significant human exposure to starch octenylsuccinates residues considering their rapid biodegradation in soil and water and lack of persistence in the environment. For the same reason, significant drinking water exposures from the use of these chemicals as inert ingredients in pesticide formulations are not anticipated.

In evaluating the potential for exposure from the use of starch octenylsuccinates in residential pesticide products, inhalation exposures are not anticipated since the compounds are not likely to volatize and are not expected to be absorbed via inhalation due to their large particle size. It is expected that dermal exposure is the primary route of exposure; however, based on their molecular weight, these chemicals are not likely to be absorbed via the dermal route. Therefore, there is no concern for dermal exposure.

Starch octenylsuccinates are widely used in a variety of consumer products. An aggregate assessment for starch octenylsuccinates was not conducted because the exposures to the chemicals by non-pesticide consumer products are not likely to result in significant residues of concern. Furthermore, starch octenylsuccinates are used as food additives and are normal constituents of the human diet.

V. Cumulative Effects

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.” Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, EPA has not made a common mechanism of toxicity finding as to starch octenylsuccinates and any other substances and, these materials do not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has not assumed that starch octenylsuccinates 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 the policy statements released by EPA's Office of Pesticide Programs concerning common mechanism determinations and procedures for cumulating effects from substances found to have a common mechanism on EPA's website at http://www.epa.gov/​pesticides/​cumulative/​.

VI. Safety Factor for Infants and Children

Section 408 of the FFDCA 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 on toxicity and exposure unless EPA determines that a different margin of safety will be safe for infants and children. Margins of safety are incorporated into EPA risk assessments either directly through use of a MOE analysis or through using uncertainty (safety) factors in calculating a dose level that poses no appreciable risk to humans. The toxicity database is sufficient for starch octenylsuccinates and potential exposure is adequately characterized given the low toxicity of starch octenylsuccinates. In terms of hazard, there are low concerns (practically non-toxic) and no residual Start Printed Page 53724uncertainties regarding prenatal and/or postnatal toxicity. No developmental toxicity studies are available in the data base. However, in the dietary study conducted in rats fed octenylsuccinate modified starch during gestation through post-natal day 90 at doses up to 30% (15 g/day), there was no systemic toxicity in female rats and their offspring. Based on lack of any systemic toxicity at doses up to 15 g/day in rats, lack of any apparent developmental effects, and lack of any systemic toxicity in weanlings at doses up to 15 g/day, EPA concluded that there is no evidence of increased susceptibility to infants and children. Given the low toxicity of starch octenylsuccinates, a safety factor analysis has not been used to assess risk. For similar reasons, including the lack of any concern regarding increased sensitivity in the young, the additional 10X FQPA safety factor for protection of infants and children is not necessary.

VII. Determination of Safety

The toxicity database is sufficient for the risk assessment of starch octenylsuccinates as specified. In terms of hazard, there are low concerns (practically non-toxic). The toxicity database does not indicate susceptibility in fetuses, thus there is no concern at this time for increased sensitivity to infants and children to starch octenylsuccinates when used as ingredients in pesticide formulations.

Dietary (food and drinking water) exposures of concern are not anticipated from the use of starch octenylsuccinate as inert ingredients in pesticide and non-pesticide products, considering their rapid biodegradation in soil and water and lack of persistence in the environment. Inhalation and dermal exposures of concern from the use of these chemicals as inert ingredients in pesticide products in residential settings are not anticipated because these compounds are not likely to volatize and are not expected to be absorbed due to their large particle size.

Considering their low toxicity (practically non-toxic), ready biodegradation in soil and water, and lack of persistence in the environment, it is unlikely that dietary and residential exposures of concern would result from the use of starch octenylsuccinates as ingredients in pesticides. An aggregate assessment for starch octenylsuccinates was not conducted because the exposures to the chemicals by non-pesticide consumer products are not likely to result in significant residues of concern.

Based on this information, EPA concludes that starch octenylsuccinates do not pose a risk to the general population, or to infants and children, under reasonably foreseeable circumstances. Therefore, EPA finds that the exemptions from the requirement of a tolerance for amylopectin, acid-hydrolyzed, 1-octenylbutanedioate (CAS Reg. No. 113894-85-2) and for amylopectin, hydrogen 1-octadecenylbutanedioate (CAS Reg. No. 125109-81-1) when used in antimicrobial formulations (food-contact surface sanitizing solutions) under 40 CFR 180.940(a), and when used in accordance with good agricultural or manufacturing practice under 40 CFR 180.950 will be safe under section 408(c) of FFDCA and is granting the requested tolerance exemptions.

VIII. Other Considerations

A. Analytical Method

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 Tolerances

The Agency is not aware of any country requiring a tolerance for amylopectin, acid-hydrolyzed, 1-octenylbutanedioate (CAS Reg. No. 113894-85-2) and for amylopectin, hydrogen 1-octadecenylbutanedioate (CAS Reg. No. 125109-81-1) nor have any CODEX Maximum Residue Levels (MRLs) been established for any food crops at this time.

IX. 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, 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) (Public Law 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).

X. 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).
