II. Background

A. What action is the Agency taking?

EPA is proposing to establish an exemption from the requirement of a tolerance for residues of the antimicrobial pesticides dipropylene glycol and triethylene glycol on food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils. EPA is proposing this exemption to cover residues of dipropylene glycol and triethylene glycol that may be found in food as a result of the use of these antimicrobials on food-contact surfaces.

As noted in the December 2017, Propylene Glycol, Dipropylene Glycol and Triethylene Glycol Interim Registration Review Decision (“Glycol Interim Decision”) (available at http://www.regulations.gov in docket ID numbers EPA-HQ-OPP-2013-0219 and EPA-HQ-OPP-2013-0218), dipropylene glycol and triethylene glycol are registered for use as disinfectants on food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils. As a result of that use, residues of dipropylene glycol and triethylene glycol may be found in food that comes into contact with treated surfaces.

According to the Agency's 2016 Antimicrobial Use Site Index (https://www.epa.gov/​pesticide-registration/​antimicrobial-pesticide-use-site-index), EPA categorizes that use as an “indirect food use.” 40 CFR 158W requires a tolerance or exemption for direct and indirect food uses. Historically, EPA did not require a tolerance or tolerance exemption for the registered uses of dipropylene glycol and triethylene glycol because the labels required a potable water rinse after application. EPA's scientific assumption had been that if an antimicrobial pesticide use required a potable water rinse on the label, residues of the pesticide would be rinsed away. With no residues available to transfer to foods coming into contact with the treated food surface, the use was considered nonfood, and no tolerance or tolerance exemption was needed. That presumption of no available residues for transfer is no longer supportable because available data now suggests that a potable water rinse may not be 100% efficient in removing residues; therefore, the Agency no longer considers a use to be “nonfood” just because the label requires a potable water rinse. Absent information supporting a conclusion that no residues would be available for transfer to food from the use, a tolerance or tolerance exemption is required. As of this time, the Agency has not received any information supporting a conclusion that residues of dipropylene glycol and triethylene glycol would not be available for transfer to food after application to food surfaces.

B. What is the Agency's authority for taking this action?

A “tolerance” represents the maximum level for residues of pesticide chemicals legally allowed in or on raw agricultural commodities and processed foods. Section 408 of FFDCA, 21 U.S.C. 346(a), authorizes the establishment of tolerances, exemptions from tolerance requirements, modifications in tolerances, and revocation of tolerances for residues of pesticide chemicals in or on raw agricultural commodities and processed foods. Without a tolerance or exemption, food containing pesticide residues are considered unsafe and therefore “adulterated” under FFDCA section 402(a), 21 U.S.C. 342(a). Such food may not be distributed in interstate commerce, 21 U.S.C. 331(a).

Section 408(e)(1)(B) of the FFDCA authorizes EPA to issue an exemption from the requirement of a tolerance on its own initiative. 21 U.S.C. 346a(e)(1)(B). It is under section 408(e) of the FFDCA that EPA is proposing to establish the exemption in this rulemaking. The standard for establishing an exemption is found in section 408(c)(2)(A) of the FFDCA and is discussed below. 21 U.S.C. 346a(c)(2)(A).

III. Aggregate Risk Assessment and Determination of Safety

Section 408(c)(2)(A)(i) of 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(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. Section 408(c)(2)(B) requires EPA to take into account, among other things, the considerations set forth in section 408(b)(2)(C) and (D). Specifically, 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 . . . .”

Consistent with FFDCA section 408(b)(2)(D), 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 to support the establishment of exemptions from the requirement of a tolerance for residues of dipropylene glycol and triethylene glycol.

As noted in the Glycol Interim Decision, there is no evidence of adverse effects for dipropylene and triethylene glycol in the toxicity database; therefore, EPA did not identify any toxicological endpoints of concern for assessing risk. Although the current uses have the potential to result in exposure to residues of dipropylene and triethylene glycol in or on food, including uses of these chemicals as inert ingredients, the low order of toxicity and low application rates from the current uses of these chemicals support a conclusion that exemptions from the requirement of a tolerance for these pesticide chemicals when used in antimicrobial formulations on food-contact surfaces in public eating places, on dairy-processing equipment, and on food-processing equipment and utensils would be safe. Based on the low order of toxicity and low exposure levels, EPA concludes that there is a reasonable certainty that no harm will result to the U.S. population, including all subpopulation groups, from aggregate exposure to dipropylene glycol or triethylene glycol. For further information, the Glycol Interim Decision can be found at https://www.regulations.gov in docket identification numbers EPA-HQ-OPP-2013-0218 (propylene and dipropylene glycol) and EPA-HQ-OPP-2013-0219 (triethylene glycol).

IV. Analytical Enforcement Methodology

An analytical method for residue is not needed. Due to the lack of risk, EPA is establishing exemptions without limits for dipropylene glycol and triethylene glycol; therefore, measuring residues of dipropylene glycol and triethylene glycol is not necessary.

V. Conclusion

Therefore, EPA is proposing to establish an exemption from the requirement of a tolerance for residues of dipropylene glycol and triethylene glycol when used in antimicrobial formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils.

IV. Statutory and Executive Order Reviews

In this document, EPA is proposing to establish exemptions from the requirement of a tolerance under FFDCA section 408(e). 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, entitled “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001), nor is it subject to Executive Order 13771, entitled “Reducing Regulations and Controlling Regulatory Costs” (82 FR 9339, February 3, 2017). 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 (UMRA) (2 U.S.C. 1501 et seq.). Nor does it require any special considerations as required by 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 other Agency action under Executive Order 13045, entitled “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997). This proposed rule 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 (NTTAA) (15 U.S.C. 272 note).

Pursuant to the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), the Agency previously assessed whether establishment of tolerances, exemptions from tolerances, raising of tolerance levels, expansion of exemptions, or revocations might significantly impact a substantial number of small entities and concluded that, as a general matter, these actions do not impose a significant economic impact on a substantial number of small entities. These analyses for tolerance establishments and modifications, and for tolerance revocations were published in the Federal Register of May 4, 1981 (46 FR 24950) and December 17, 1997 (62 FR 66020) (FRL-5753-1), respectively, and were provided to the Chief Counsel for Advocacy of the Small Business Administration. Taking into account this analysis, and available information concerning the pesticides listed in this proposed rule, the Agency hereby certifies that this proposed rule will not have a significant negative economic impact on a substantial number of small entities. Furthermore, for the pesticides named in this proposed rule, the Agency knows of no extraordinary circumstances that exist as to the present proposed rule that would change EPA's previous analysis. Any comments about the Agency's determination should be submitted to the EPA along with comments on the proposed rule and will be addressed prior to issuing a final rule.

In addition, the Agency has determined that this proposed rule 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 proposed rule 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 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 9, 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.
