Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to add a new section to part 180 which lists the pesticide chemicals that are exempt from the requirement of a tolerance when used in food-contact surface sanitizing solutions. The initial list of exempt pesticide chemicals in the new section is duplicated from the Food and Drug Administration's (FDA) regulations in 21 CFR 178.1010. EPA is also changing FDA's naming conventions for some of the chemical substances that were duplicated.

Until recently, FDA under the Federal Food, Drug, and Cosmetic Act (FFDCA) section 409, regulated food-contact surface sanitizing solutions. With the amendments to FFDCA by the Food Quality Protection Act (FQPA) of 1996 and by the Antimicrobial Regulation Technical Corrections Act (ARTCA) of 1998, these responsibilities have been restructured. Under FFDCA section 408, EPA will now regulate the pesticide uses of these chemical substances and FDA under FFDCA section 409 will continue to regulate any indirect food additive uses of these chemical substances.

Registrants of existing food-contact surface sanitizing solutions that contain chemical substances other than those listed in this proposed rule should identify these chemical substances and support their claim that the chemical substance is generally recognized as safe (GRAS), or permitted by FDA prior sanction, or approval, or subject to a letter of no objection in order to remain exempt from the requirement of a FFDCA section 408 tolerance.

DATES:

Comments, identified by docket ID number OPP-2003-0121, must be received on or before July 25, 2003.

Registrants should identify chemical substances not listed in this document and support their claims of GRAS, or prior sanction, or approval, or no objection of these chemical substances by submission of such information to the person listed under FOR FURTHER INFORMATION, on or before October 1, 2003.

ADDRESSES:

Comments may be submitted electronically, by mail, or through hand delivery/courier. Follow the detailed instructions as provided in Unit I. of the SUPPLEMENTARY INFORMATION.

Registrants identifying chemical substances not listed in this document and the supporting documentation for their claims of GRAS, or prior sanction, or approval, or no objection of these chemical substances for inclusion in 40 CFR 180.940 should submit the information directly to the person listed under FOR FURTHER INFORMATION. Start Printed Page 37779 Identification of a chemical substance is not a comment and should be identified as “Submission of Non-designated Prior Approved Substance.”

II. What is the Agency's Authority for Taking this Action?

This proposed rule is issued under FFDCA section 408, 21 U.S.C. 346a, as amended by FQPA (Public Law 104-170), and ARTCA (Public Law 105-324).

Section 408 of FFDCA authorizes the establishment of tolerances, exemptions from the requirement of a tolerance, modifications in tolerances, and revocation of tolerances for residues of pesticide chemicals in or on raw agricultural commodities and processed foods. Section 408(j)(2) of FFDCA provides that all regulations issued by FDA under FFDCA section 409 that stated conditions for safe use of substances that are now, post-FQPA, considered pesticide chemical residues in or on processed food or that otherwise stated the conditions under which such pesticide chemicals could be safely used, shall be deemed to be regulations issued under FFDCA section 408.

Due to the FQPA and ARTCA amendments to FFDCA, those chemical substances originally regulated by FDA under FFDCA section 409 as food-contact surface sanitizing solutions are now the responsibility of EPA. These pesticide chemical regulations are now subject to modification or revocation at EPA's initiative under FFDCA section 408(e). The Agency is proposing to duplicate the substance of FDA's food additive regulations for those chemical substances found in 21 CFR 178.1010 which are now pesticide tolerance exemptions in a format consistent with EPA's authority under section 408 in a new section, 40 CFR 180.940.

EPA's rulemaking activity will have no effect on any of the FDA regulated FFDCA section 409 food additive regulations in 21 CFR 178.1010.

III. Summary of this Action

A. Why is There an Overlap of EPA's and FDA's Regulatory Authorities?

Since EPA was created in 1970, EPA and FDA have shared authority under FFDCA over pesticide chemical residues in food. Enactment of FQPA in 1996 amended FFDCA, and shifted to EPA regulatory authority over certain pesticide residues which were previously subject to FDA authority. Prior to 1996, products used to sanitize or disinfect permanent or semi-permanent food-contact surfaces were regulated by FDA as indirect food additives under FFDCA section 409. Under the FQPA and ARTCA amendments to FFDCA, antimicrobial formulations used on permanent or semi-permanent food-contact surfaces other than food packaging are now considered “pesticide chemicals” and are regulated by EPA under FFDCA section 408.

FQPA added a provision to FFDCA to assure an orderly transition to the new regulatory system. Section 408(j)(2) of FFDCA provides that all food additive regulations issued under FFDCA section 409 prior to the enactment of FQPA for antimicrobial uses that became pesticide chemical uses subsequent to FQPA and that were not affected by ARTCA shall be deemed to be regulations issued under FFDCA section 408. Thus, FQPA converted existing food additive regulations issued by FDA under FFDCA section 409, for chemical substances that post-FQPA became pesticide chemicals, into FFDCA section Start Printed Page 37781408 pesticide chemical tolerances or tolerance exemptions. This “grandfather” provision of FFDCA section 408(j) assures that pesticide chemical residues conforming to regulations issued under the authority of FFDCA section 409 will not render food adulterated as a result of the jurisdictional shift from FDA to EPA.

In 1998, ARTCA amended the definition of “pesticide chemical” in FFDCA section 201(q) so as to exclude certain antimicrobial pesticide residues from the authority of FFDCA section 408. Consistent with FFDCA section 408(j)(4), these residues now fall within the authority of FFDCA section 409. As a result, certain uses of food-contact surface sanitizing solutions identified in FDA's regulations at 21 CFR 178.1010 remain subject to FFDCA section 409 regulations just as they did pre-FQPA, while other uses are now subject to EPA's jurisdiction under FFDCA section 408.

B. Why are these Tolerance Exemptions not Subject to Tolerance Reassessment at this Time?

Under FFDCA section 408(q), EPA is required to reassess all tolerance exemptions that were in effect on the day before the enactment of the FQPA. The tolerance exemptions for inert ingredients as well as those active ingredients not yet completed will be reassessed in accordance with EPA's schedule for tolerance reassessment published in the Federal Register of August 4, 1997 (62 FR 42019) (FRL-5734-6).

The tolerance exemptions in this proposed rule to be codified in 40 CFR 180.940 already exist as valid FFDCA section 408 regulations. FDA promulgated the food additive regulations in 21 CFR 178.1010 under the authority of FFDCA section 409 prior to the enactment of FQPA. By operation of FFDCA section 408(j)(2), those portions of 21 CFR 178.1010 that pertain to chemical substances that are pesticide chemicals post-FQPA and remain as such post-ARTCA were converted to FFDCA section 408 tolerance exemptions. EPA's duplication of these tolerance exemptions is not “establishing, modifying, or revoking a tolerance” under FFDCA section 408(b). EPA is, therefore, not required to conduct a full reassessment of these tolerance exemptions at this time.

C. Why is 40 CFR 180.940 being Created?

The Agency is duplicating in 40 CFR 180.940 only those portions of the regulations in 21 CFR 178.1010 that pertain to pesticide chemicals. This duplication will have no effect on any of FDA's regulated FFDCA section 409 food additive regulations in 21 CFR 178.1010.

In establishing food additive regulations for food-contact surface sanitizing solutions in 21 CFR 178.1010, FDA used a formulation-specific approach. Consistent with its authority under FFDCA section 409, FDA issued regulations prescribing the conditions under which food-contact surface sanitizing solutions might be safely used. FDA approved the use of each food-contact surface sanitizing solution formulation as a whole, rather than regulating each component chemical substance individually. In addition, FDA included a generic exemption for any chemical substance considered to be GRAS, and in some cases, issued letters not objecting to certain additional chemical substances in the formulations.

By contrast, FFDCA section 408 authorizes EPA to issue regulations establishing tolerances or exemptions from the requirement of a tolerance. EPA's practice has been to issue these regulations on a chemical-specific basis, whereby each ingredient in the product is the subject of a separate tolerance or exemption regulation. Food-contact surface sanitizing solutions meet the requirements of FFDCA if each ingredient has an appropriate clearance under FFDCA, either a tolerance or an exemption from the requirement of a tolerance, and any conditions on the clearance are observed.

Translating the regulatory decisions made by FDA into a comparable EPA scheme requires considerably greater work on EPA's part than merely copying those portions of the existing regulations in 21 CFR 178.1010 that pertain to pesticide chemicals directly into 40 CFR 180.940. EPA must disaggregate the formulations in 21 CFR 178.1010 that pertain to pesticide chemicals into their component ingredients. EPA must also provide a mechanism to address those ingredients not identified by name in 21 CFR 178.1010 but that were, for example, permitted by prior sanction or approval, not objected to, or generally recognized as safe. This, in fact, places a higher initial demand on EPA resources than would be required to simply copy FDA's approach. However, EPA is convinced that the long-term administrative convenience of using a consistent regulatory scheme for all pesticide chemicals subject to FFDCA section 408 outweighs the initial burdens.

FDA's formulation-specific approach is different from EPA's chemical-specific approach. Under EPA's approach, a tolerance exemption would be approved once for each particular pesticide chemical, and would not need to be repeated as new products containing that chemical substance enter the market. EPA's approval process is not complex, will allow for a wide variety of potential products, and fosters innovative formulation approaches. In addition, by listing in one place (40 CFR 180.940) all chemical substances exempted from the requirement of a tolerance when used in food-contact surface sanitizing solutions, EPA's approach will increase the transparency of its regulatory process.

This duplication will not allow any residues beyond those already permitted by 21 CFR 178.1010. EPA believes that the chemical-specific approach and FDA's formulation-specific approach are equivalent from a risk management perspective, inasmuch as each would result in the same levels of residues from these chemical substances.

As part of the duplication, EPA changed the naming conventions (chemical nomenclature), as well as combining, as appropriate, chemical substances that appear in 21 CFR 178.1010 under two or more names under a single name. The Agency has attempted to identify each of the listed chemical substances using the Chemical Abstracts Service Registry Number (CAS No.). The CAS No. provides one of the most distinct and universally accepted means of identifying chemical substances. Generally, there will be only one CAS No. per listed chemical substance; however, it is possible that more than one CAS No. may be appropriate for some chemical substances. The lack of a CAS No. will not preclude EPA from including chemical substances in 40 CFR 180.940.

The lower-concentration limits specified in 21 CFR 178.1010 are not included in 40 CFR 180.940 because of the differences between FDA's approach and EPA's approach. Although EPA establishes tolerance exemptions for use in food-contact surface sanitizing solutions under FFDCA, all pesticide products must also meet the criteria for registration under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) before being offered for sale. EPA relies on conditions imposed through the FIFRA registration process to address safety and for antimicrobial-formulated products efficacy. Accordingly, the lower limits on concentrations of pesticide chemicals, that appear in 21 CFR 178.1010 will not appear in 40 CFR 180.940. Three types of food-contact surface sanitizing Start Printed Page 37782solutions are described in 21 CFR 178.1010:

  • Those used on food-contact surfaces in public eating places.
  • Those used on dairy-processing equipment.
  • Those used on food-processing equipment and utensils.

According to FDA, food-contact surface sanitizing solutions that are acceptable for use on food-contact surfaces in public eating places can also be used on dairy-processing equipment, and on food-processing equipment and utensils. Food-contact surface sanitizing solutions that are acceptable for use on dairy equipment can also be used on food-processing equipment and utensils. EPA has separated the component ingredients by both chemical and concentration for these three types of food-contact surface sanitizing solutions, which will be included in 40 CFR 180.940.

IV. Issuance and Withdrawal of Direct Final Rule

In the Federal Register of December 3, 2002 (67 FR 71847) (FRL-6824-2), the Agency published a direct final rule to establish 40 CFR 180.940. Comments were received. In the December 3, 2002 Federal Register notice, EPA announced that it would withdraw the direct final rule if it received adverse comment, and proceed with proposed rule as provided by section 553 of the Administrative Procedure Act, 5 U.S.C. 553. Because some of the comments were of a nature that would warrant a response if made on a proposed rule, they are adverse comments that require withdrawal of the direct final rule. Accordingly, EPA withdrew the direct final rule on March 24, 2003 (68 FR 14165) (FRL-7299-4).

Several of the comments reflected some understandable confusion on the part of the commenters. While EPA's chemical-specific approach and FDA's formulation specific approach are essentially equivalent, the two approaches look and read differently. EPA disaggregated the 46 formulations in 21 CFR 178.1010 into a list of chemicals. This list of chemicals was then subdivided into three separate lists based on use categories in 21 CFR 178.1010 (i.e., food-contact surfaces in public eating places, dairy processing equipment, and food-processing equipment and utensils). The 40 CFR 180.940(a) list contains only the chemicals specified in those formulations that were designated by FDA for use in public eating places. The 40 CFR 180.940(b) list contains only the chemicals specified in those formulations that were designated by FDA for use on dairy equipment. The 40 CFR 180.940(c) list contains all chemicals because all formulations in 21 CFR 178.1010 can be used on food-processing equipment and utensils.

The maximum concentration level for each chemical was determined by evaluating the range derived from the lists in 40 CFR 180.940(a), (b), or (c). Where 21 CFR 178.1010 authorized several different sanitizing solutions each containing a particular chemical, but at different concentrations, EPA will use only the highest concentration as the upper limit, reflecting FDA's implicit determination that concentrations up to and including that limit do not compromise food safety. As an example, if three solutions authorized under 21 CFR 178.1010 for use on dairy equipment contain chemical “X” at concentrations of 150, 200, and 240 parts per million (ppm), then 240 ppm would be used as the upper limit in 40 CFR 180.940(b). If for chemical “Y,” concentrations of 150 and 200 ppm were specified, but in a third solution the concentration was not specified, then the upper limit for chemical “Y ” in 40 CFR 180.940(c) would be specified as “none.” This reflects FDA's implicit determination in regard to that third sanitizing solution that chemical “Y ” could be used in any concentration without significant risk to food safety.

In addition to the disaggregation, the Agency also in some cases used a different chemical nomenclature. CI (chemical index) names and CAS Nos. were used to the greatest extent possible. This is part of an Agency-wide effort to provide a common and consistent way to identify and represent chemical substances across the Agency. Thus, sodium hypochlorite became hypochlorous acid, sodium salt. In other instances (most commonly involving polymers or quaternary ammonium compounds), FDA approved in one solution a particular chemical that falls within a more inclusive chemical designation approved in another solution. If practicable in such instances, EPA has stated the tolerance exemption only in terms of the more inclusive chemical designation, implicitly exempting all chemical substances that fall within that designation. For example, n-alkyl (C12-C16) benzyl dimethyl ammonium chloride would be considered to be a subset of n-alkyl (C12-C18) benzyl dimethyl ammonium chloride. Another example, n-alkyl (C12-C18) benzyl dimethyl ammonium chloride (mw 351 to 380) would also be considered a subset of n-alkyl (C12-C18) benzyl dimethyl ammonium chloride. Both of the example chemicals would be accounted for under the nomenclature quaternary ammonium compounds alkyl (C12-C18) benzyl dimethyl, chlorides. For each comment questioning whether a particular chemical substance appeared in the direct final rule, the Agency was able to verify that the chemical for which the commenter expressed concern was included in 40 CFR 180.940, albeit under a different designation.

A commenter asked that instead of using the term “oxychloro species,” that sodium chlorite or chlorine dioxide should be used instead. The “generated by” language was considered to be confusing in a listing of chemical names. The Agency (as acknowledged by the commenter) used FDA's language, which is an approach which describes the process for generating the solution, not the components of the solution. If the end-products of the generation process were specific chemicals already included in the other solutions (and therefore already line-items), then the Agency used the disaggregated approach. However, for the oxychloro species generation methods described in 21 CFR 178.1010(b)(34), the chlorite, chlorate, and/or chlorine dioxide is actually an equilibrium mixture. There are no separate line-item entries for these chemicals. In fact, the upper concentration limit is specified in terms of chlorine dioxide only, thus making it difficult to separate the chemicals into line items. The Agency determined therefore to maintain the original FDA language at this time. The Agency also considered that other generation methods for oxychloro species could be submitted as part of the non-designated prior approved chemical substances, which could impact the handling of this in the future.

Several commenters asked if a specific combination of quaternary ammonium compounds expressly identified in 21 CFR 178.1010(b)(22) were included in 40 CFR 180.940. Each of the component chemicals identified in 21 CFR 178.1010(b)(22) are identified in 40 CFR 180.940 as subject to a tolerance exemption. The two components listed in 21 CFR 178.1010(b)(22) are di-n-alkyl (C8-C10) dimethylammonium chloride (mw 332 to 361) and n-alkyl (C12-C18) benzyl dimethyl ammonium chloride (mw 351 to 380). The first chemical is listed in 40 CFR 180.940 as “Quaternary ammonium compounds, di-n-alkyl (C8-C10) dimethyl ammonium chloride average molecular weight (in amu) 332 to 361.” 21 CFR 178.1010(b)(22) and 21 CFR 178.1010(c)(17) together allow a maximum end-use concentration of 400 Start Printed Page 37783ppm of the two quaternary ammonium compounds in this solution, of which this particular chemical must comprise 60%. EPA's regulation exempts this chemical substance from the requirement of a tolerance in sanitizing solutions up to 240 ppm, which is 60% of the 400 ppm authorized in the FDA regulations. The second chemical is listed in 40 CFR 180.940 as “Quaternary ammonium compounds, alkyl (C12-C18) benzyl dimethyl, chlorides.” The end use concentration as specified in 21 CFR 178.1010(b)(22) and 21 CFR 178.1010(c)(17) for this chemical would be 40% of 400 ppm or 160 ppm. Because other solutions in 21 CFR 178.1010 included chemical substances within the description “quaternary ammonium compounds, alkyl (C12-C18) benzyl dimethyl, chlorides” without molecular weight limitations and/or with higher concentration limits, the description of this chemical in 40 CFR 180.940 is more broad than that of 21 CFR 178.1010(b)(22).

Based on one comment, the Agency was made aware of a typographical error in the December 3, 2002 Federal Register notice which has been corrected in this notice of proposed rulemaking. In 40 CFR 180.940(a) the upper limit should be not 150 ppm, but 200 ppm for C12-C16 benzyl dimethyl ammonium chloride (mw 351-380). With the change in upper limit to 200 ppm, C12-C16 benzyl dimethyl ammonium chloride (mw 351 to 380) can be appropriately held under the more inclusive quaternary ammonium compounds alkyl (C12-C18) benzyl dimethyl, chlorides.

Another commenter requested that the Agency change the language describing the upper limit concentration for all quaternary ammonium compounds. The commenter has suggested the use of the phrase “when ready to use, the end-use concentration is not expected to exceed ‘X’ ppm of this active quaternary ammonium compound,” instead of the phrasing used by the Agency “when ready for use, concentration is not to exceed ‘X’ ppm of active quaternary compound.” The commenter cited the concern that state enforcement personnel would apply the limitation for a particular quaternary ammonium compound to a mixture. The Agency believes that the language it has used is clear and concise. The concentration limits specified in 40 CFR 180.940 apply only to the chemical substance described in the particular table entry. However, the 30-day comment period will allow the Agency to take further comment on this issue.

A commenter asked that the Agency not distinguish between food-contact surfaces in public eating places, dairy-processing equipment, and food processing equipment and utensils. These categories were originally created by the FDA and reflect different assumptions especially with regard to dietary exposure to sanitizer residues, and thus are an intrinsic part of FDA's risk assessments. Although EPA has the authority to reconsider FDA's risk assessments, EPA can do so only upon fully reassessing these tolerance exemptions in accordance with FFDCA section 408, as amended by FQPA. EPA is not reassessing these tolerance exemptions at this time, but instead merely duplicating FDA's previous clearances in a format consistent with EPA's authority under FFDCA section 408. EPA is required under FFDCA section 408(q)(1)(C) to complete tolerance reassessment for all pesticide chemicals by 2006, and will consider the commenter's suggestion during tolerance reassessment.

Although not raised by commenters, EPA has made three additional changes from the December 3, 2003 Federal Register notice. D&C Blue No.1 (methylene blue) is now referenced as methylene blue. Similarly, FD&C Yellow No. 5 (tartrazine) is now referenced as FD&C Yellow No. 5. A CAS No. was added to one entry (quaternary ammonium compounds, alkyl (C12-C18) benzyl dimethyl, chlorides) in 40 CFR 180.940(a).

V. Addition of Non-Designated, Prior Approved Chemical Substances

21 CFR 178.1010 allows the use of GRAS chemical substances and chemical substances “permitted by prior sanction or approval,” that are not expressly identified. These chemical substances were subject to the sanitizer formulation approval under FDA's regulation before these uses became FFDCA section 408 tolerance exemptions under FFDCA section 408(j)(2). Accordingly, many food-contact sanitizing solutions that presently are authorized for use under 21 CFR 178.1010 contain ingredients which are not identified in this direct final rule. As discussed in this unit, EPA is asking registrants to identify these other ingredients that they believe should be included in 40 CFR 180.940. EPA intends to publish a revision to 40 CFR 180.940 adding these chemical substances. In the interim, to preserve the use of food-contact surface sanitizing solutions that were cleared for use before FQPA's enactment and that contain chemical substances that are not specifically identified in 21 CFR 178.1010, EPA has decided to honor those approvals under 21 CFR 178.1010 until EPA has received and reviewed registrant's claims with respect to unspecified pesticide chemicals, as discussed in this unit.

FDA's regulations (21 CFR 178.1010(b)) allowed the addition to food-contact surface sanitizing solutions of GRAS components, and components permitted by prior sanction or approval or subject to a letter of no objection. Much of this information should be in EPA's files. The Agency will access this information. However, EPA may not have ready access to all information on all chemicals in existing food-contact surface sanitizing solution formulations which could meet these criteria. Submission of this information to EPA would also reduce the possibility of an existing food-contact surface sanitizing solution having a component that lacks a tolerance exemption under 40 CFR 180.940. Therefore, registrants who believe that components of their food-contact surface sanitizing solutions are exempted under 21 CFR 178.1010(b) should advise EPA in writing that these chemical substances (along with the CAS No.) should be included in 40 CFR 180.940. The submission of this information facilitates EPA's process for adding these chemical substances cleared under 21 CFR 178.1010(b), but not specifically listed by name, to 40 CFR 180.940. The EPA will also need any available information documenting the claim that the component is GRAS, prior sanctioned or approved, or subject to a letter of no objection.

Claims and supporting documentation should be sent to the person listed under FOR FURTHER INFORMATION CONTACT. Claims are not comments on this direct final rule and should be identified on the subject line as “Submission of Non-designated Prior Approved Chemical Substance.” If you have any questions about the many types of information that could be submitted please consult the person listed under FOR FURTHER INFORMATION CONTACT. The Agency does not anticipate that registrants will be required to submit an excessive amount of information, and, in fact, believes that most registrants will be able to submit the necessary information with minimal effort. EPA will review and evaluate the information provided. Chemical substances identified in claims received not later than October 1, 2003, may be eligible for inclusion in 40 CFR 180.940 under FFDCA section 408(j)(2). EPA anticipates publishing a notice of proposed rulemaking identifying those chemical substances shortly after that date.Start Printed Page 37784

VI. Statutory and Executive Order Reviews

This proposed rule would add a new § 180.940 to 40 CFR part 180, subpart D, which lists the pesticide chemicals that are exempt from the requirement of a tolerance when used in food-contact surface sanitizing solutions. The initial list duplicates pesticide chemicals in 40 CFR 180.940 that are active and inert ingredients listed in 21 CFR 178.1010. Since this proposed rule does not impose any new requirements, it is not subject to review by the Office of Management and Budget (OMB) 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 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).

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.

Under section 605(b) of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), the Agency hereby certifies that the creation of a new section 180.940 will not have significant negative economic impact on a substantial number of small entities. The rationale supporting this conclusion is as follows. This proposed rule does not impose any requirements, it establishes exemptions from the requirement for a tolerance. The Agency is, however, also commencing a process whereby EPA will require certain persons to identify chemical substances considered to be GRAS (which could include self-affirmed GRAS chemicals), or permitted by prior sanction or approval in existing food contact surface sanitizing solutions. The information available to the Agency indicates that fewer than 500 companies have approximately 1,300 products that could fall under this category. EPA anticipates the economic burden on small entities to be minor, since the Agency is only asking for confirmation that the chemical substances considered to be GRAS or permitted by prior sanction or approval in existing food contact surface sanitizing solutions are in fact part of an existing formulation, and information as to why the chemical is considered to be GRAS, or a copy of an FDA letter not objecting to the use of a chemical substance. By contrast, this proposed rule will be beneficial to the regulated community by increasing the number of inert ingredients for use in antimicrobial formulations and by reducing the regulatory burden on persons seeking to market new combinations of ingredients for certain hard surface sanitizing solutions. Additionally, this proposed rule will provide a more transparent listing of pesticide chemicals used in food-contact surface sanitizing solutions to the public.

According to the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., an Agency may not conduct or sponsor, and a person is not required to respond to a collection of information that requires OMB approval under the PRA, unless it has been approved by OMB and displays a currently valid OMB control number. The OMB control numbers for EPA's regulations, after initial display in the preamble of the final rule and in addition to its display on any related collection instrument, are listed in 40 CFR part 9.

This proposed rule does not impose any new information collection requirements that would require separate approval by OMB under the PRA. Under 5 CFR 1320.3(h), the request for information discussed in Unit V. is not subject to approval under the PRA, and the information collection activities related to the Agency's tolerance exemption process have already been approved by OMB under OMB control numbers 2070-0024 (EPA ICR No. 597). The annual “respondent” (petitioner) burden for the pesticide tolerance petitions program is estimated to average 1,726 hours per petition. According to the PRA, “burden” means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. For this collection, it is the time reading the regulations, planning the necessary data collection activities, conducting tests, analyzing data, generating reports and completing other Start Printed Page 37785required paperwork, and storing, filing, and maintaining the data. Send comments regarding this burden estimate or any other aspect of the collection activity, including suggestions for reducing the burden to: Director, Collection Strategies Division (2822), Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-0001. Include the OMB control number 2070-0024 in any correspondence about this collection activity, but do not submit the requested information or forms to this address.
