SUPPLEMENTARY INFORMATION:

I. Background

In a notice published in the Federal Register of August 10, 2010 (75 FR 48353), we announced that the U.S.P., 12601 Twinbrook Pkwy., Rockville, MD 20852, had filed a food additive petition. The petition proposed that select food additive regulations in parts 172, 173, 178, and 180 (21 CFR parts 172, 173, 178, and 180), which incorporate by reference food-grade specifications from prior editions of the FCC, be amended to incorporate by reference food-grade specifications from FCC 7.

The FCC is a compendium of specification monographs for substances used as food ingredients. The Committee on Food Chemicals Codex of the Food and Nutrition Board, Institute of Medicine (IOM) of the National Academies published the first through fifth editions of the FCC. In 2006, U.S.P. acquired the rights to the FCC, and subsequently published the sixth, seventh, and eighth editions. Specifications and methods published in the FCC have been incorporated by reference in various sections of 21 CFR parts 73, 170, 172, 173, 178, 180, and 184.

Since acquiring rights to the FCC, U.S.P. has developed and continues to develop standards for food ingredients through public participation with a goal of biennial publication of the FCC. Draft monographs and data are provided by food ingredient manufacturers, users, and suppliers and are published for public review and comment on U.S.P.'s Web site. U.S.P. scientists and its Food Ingredients Expert Committee review these data and, if necessary, conduct laboratory tests. Once approved by the Food Ingredients Expert Committee, new or updated monographs are published in the next edition or Supplement to the FCC.

The petitioner initially requested amendments to 39 existing references to older editions of the FCC in parts 172, 173, 178, and 180 to incorporate by reference the specifications contained in FCC 7. The petitioner explained that of the regulations it has requested to be updated, 15 regulations refer to the third edition of the FCC (FCC III, published in 1981); 18 regulations refer to the fourth edition of the FCC (FCC IV, published in 1996); 4 regulations refer to the fifth edition of the FCC (FCC V, published in 2004); and 2 regulations refer to the sixth edition of the FCC (FCC 6, published in 2008). (The IOM used roman numerals when referring to editions of the FCC, e.g., FCC III and FCC V. U.S.P. uses numbers rather than roman numerals to refer to the editions of FCC that it has published, e.g., FCC 6 and FCC 7.) In most cases, the references to the FCC in the regulations are to an entire FCC monograph. Some references, however, only refer to part of an FCC monograph, i.e., a single specification, or to an FCC analytical method.

After discussions with us in July 2011, the petitioner subsequently narrowed its petition to exclude six regulations ((§§ 172.172.723(b)(3), 172.833(b)(4), 172.846(b), 172.858(a), 180.25(b), and 180.30(a)). The current regulation for epoxidized soybean oil (§ 172.723(b)(3)) includes a limit of 10 milligrams per kilogram (mg/kg) for heavy metals (as lead (Pb)), as determined by Method II of the “Heavy Metals Test” in FCC IV. FCC 7, however, does not include a monograph for epoxidized soybean oil and does not include the “Heavy Metals Test” as a general test in the appendices of FCC 7. Accordingly, § 172.723(b)(3) has been excluded from the petition. U.S.P. has excluded the remaining five regulations (§§ 172.833(b)(4), 172.846(b), 172.858(a), 180.25(b), and 180.30(a)) based on its need to further investigate the bases for such updates.

The petitioner cited several reasons for updating the references to older editions of the FCC to specifications and analytical methodologies contained in FCC 7. First, previous editions of the FCC are no longer readily available to industry or the public, since U.S.P. does not maintain and therefore cannot provide copies of monographs from FCC III, IV, or V to industry or the public. (Under 5 U.S.C. 552(a) and 1 CFR 51.7(a)(4), a publication that is to be incorporated by reference must be “reasonably available” to and capable of being used by persons affected by the publication.) Second, the petitioner maintained that updating the references to older editions of the FCC to FCC 7 may avoid confusion, inconsistency, and lack of uniformity in the quality of food additives and ingredients manufactured and sold. Third, the petitioner noted that, in many cases, the editions of the FCC prior to FCC 7 may employ outdated analytical methodologies and equipment that do not reflect current scientific practices, and which may be difficult to obtain.

We note that, subsequent to our analysis of FCC 7, the U.S.P. published the eighth edition of the FCC (FCC 8) in March 2012. Initiating a review of FCC 8 at this time would delay issuance of this final rule. To avoid a delay in updating the references to the FCC in our food additive regulations, we are proceeding with issuing this final rule to incorporate by reference FCC 7. The specific food additive regulations explain how to obtain copies of FCC 7. As appropriate, we will provide further updates to our food additive regulations to reflect more recent versions of the FCC.

II. Evaluation of Amendments to Parts 172, 173, 178, and 180

We compared the specifications and analytical methods in the versions of the FCC currently referenced in the regulations to the specifications and analytical methods in FCC 7 (Ref. 1). In addition, we note that some general changes were made to FCC monographs published in or after FCC IV that remain in FCC 7. One change is that the older FCC monographs discussed in this document that contain a specification limit for heavy metals (as Pb) were updated in FCC V to remove this specification, and, when appropriate, to replace it with an individual specification limit for each relevant heavy metal. Many FCC 7 monographs have also adopted lower lead limit specifications compared to earlier FCC editions, to reduce lead in food. Furthermore, if an earlier edition of the FCC contained a specification limit for arsenic, that specification has been removed unless the monograph met one of the following criteria: (1) The ingredient or additive is a high-volume consumption item (greater than 25 million pounds per year), (2) the ingredient or additive is derived from a natural (mineral) source where arsenic may be an intrinsic contaminant, and/or (3) there is reason to believe that arsenic constitutes a significant part of the total heavy metals content (Ref. 1).

An FCC monograph typically consists of a description of the substance, its functional use, the recommended specifications for the substance, and testing methodology. In many cases, there are minor differences between the description or functional use of a substance provided in FCC 7 compared to the description or functional use of a substance provided in earlier editions of the FCC and the CFR. However, FCC 7 provides the description and functional use of a substance specified in a monograph for informational purposes, e.g., to help industry understand the possible functions of the ingredients, rather than as a required standard. Other differences (e.g., solvent or instrument changes) between the specifications and analytical methods in the version of the FCC currently referenced in the regulations and the specifications and analytical methods in FCC 7 are discussed further in the FDA Memoranda from D. Folmer to M. Honigfort (Refs. 1 through 3).

After review of each proposed amendment, we are updating the regulations shown in table 1 to incorporate FCC 7 by reference. We note that the safety of these additives has been previously considered and there are no safety concerns with the proposed changes to incorporate by reference the specifications and analytical methodologies contained in FCC 7. We are also amending § 178.1005 to incorporate by reference the specifications for “Acidity,” “Chloride” and “Other requirements” for Hydrogen Peroxide Concentrate in the United States Pharmacopeia, 36th Revision (2013). This updates the reference to the United States Pharmacopeia XX (1980) already cited in § 178.1005. We compared the United States Pharmacopeia XX (1980) monograph for Hydrogen Peroxide Concentrate to the United States Pharmacopeia, 36th Revision (2013) monograph for Hydrogen Peroxide Concentrate and determined that this update is safe and appropriate (Ref. 4).

The petitioner also requested amending § 173.115(b)(3) (Alpha-acetolactate decarboxylase (α-ALDC) enzyme preparation derived from a recombinant Bacillus subtilis). The current regulation requires that the enzyme preparation should meet the general and additional requirements for enzyme preparations found in FCC IV. FCC 7 specifically includes α-ALDC in the list of enzyme preparations, but does not contain an assay method specific to α-ALDC. We are not amending § 173.115(b)(3) at this time to incorporate by reference the specifications in FCC 7 because the assay method for α-ALDC has been omitted from FCC 7.

Additionally, on our own initiative, we are amending certain provisions in parts 172, 173, 178, and 180 to update the address at which copies of FCC 7 can be examined. In most cases, the existing regulations refer to an FDA address at “5100 Paint Branch Pkwy., College Park, MD 20740.” However, in 2013, we consolidated our library holdings at our main library at 10903 New Hampshire Ave., Silver Spring, MD 20993. Therefore, we are amending various provisions to reflect the current FDA address at which copies of FCC 7 can be examined.

III. Conclusion

We reviewed data in the petition and other relevant material and conclude that the proposed amendments to the regulations listed in table 1 to incorporate by reference food-grade specifications and analytical methodologies from FCC 7, as discussed in Section II of this document, are safe and appropriate. Therefore, we are amending parts 172, 173, 178, and 180 as set forth in this document.

IV. Public Availability of Documents

In accordance with § 171.1(h) (21 CFR 171.1(h)), the petition and the documents that we considered and relied upon in reaching our decision to approve the petition will be made available for public disclosure (see FOR FURTHER INFORMATION CONTACT). As provided in § 171.1(h), we will delete from the documents any materials that are not available for public disclosure.

V. Environmental Impact

Under part H in § 171.1(c), either an environmental assessment under 21 CFR 25.40 or a claim of categorical exclusion under § 25.30 (21 CFR 25.30) or § 25.32 (21 CFR 25.32) is required to be submitted with a food additive petition. As initially filed by U.S.P., the petition contained a claim of categorical exclusion under § 25.30(i), which applies to corrections and technical changes in regulations. We reviewed the petitioner's claim of categorical exclusion and stated in our original filing notice of August 10, 2010, that we agreed that, under § 25.30(i), the proposed action was of a type that would not individually or cumulatively have a significant effect on the human environment and therefore that neither an environmental assessment nor an environmental impact statement would be required.

However, upon further review, we decided that as a group, the actions being requested are neither corrections nor technical changes and therefore the categorical exclusion in § 25.30(i) would not be applicable. Accordingly we announced, in an amended filing notice published in the Federal Register of January 18, 2012 (77 FR 2492), that U.S.P. had submitted an environmental assessment for the petition in lieu of a claim of categorical exclusion and that we would review the potential environmental impact of the petition. We placed the petitioner's environmental assessment on display in the Division of Dockets Management for public review and comment.

We have carefully reviewed the environmental assessment and considered the potential environmental effects of this action. We have concluded that the action will not have a significant impact on the human environment, and that an environmental impact statement is not required. Our finding of no significant impact and the evidence supporting that finding, contained in the environmental assessment, may be seen in the Division of Dockets Management (see ADDRESSES) between 9 a.m. and 4 p.m., Monday through Friday.

VI. Paperwork Reduction Act of 1995

This final rule contains no collection of information. Therefore, clearance by the Office of Management and Budget under the Paperwork Reduction Act of 1995 is not required.

VII. Objections

If you will be adversely affected by one or more provisions of this regulation, you may file with the Division of Dockets Management (see ADDRESSES) either electronic or written objections. You must separately number each objection, and within each numbered objection you must specify with particularity the provision(s) to which you object and the grounds for your objection. Within each numbered objection, you must specifically state whether you are requesting a hearing on the particular provision that you specify in that numbered objection. If you do not request a hearing for any particular objection, you waive the right to a hearing on that objection. If you request a hearing, your objection must include a detailed description and analysis of the specific factual information you intend to present in support of the objection in the event that a hearing is held. If you do not include such a description and analysis for any particular objection, you waive the right to a hearing on the objection. It is only necessary to send one set of documents. Identify documents with the docket number found in brackets in the heading of this document. Any objections received in response to the regulation may be seen in the Division of Dockets Management between 9 a.m. and 4 p.m., Monday through Friday, and will be posted to the docket at http://www.regulations.gov.

VIII. Section 301(ll) of the Federal Food, Drug, and Cosmetic Act

Our review of this petition was limited to section 409 of the Federal Food, Drug, and Cosmetic Act (the FD&C Act) (21 U.S.C. 348). This final rule is not a statement regarding compliance with other sections of the FD&C Act. For example, the Food and Drug Administration Amendments Act of 2007, which was signed into law on September 27, 2007, amended the FD&C Act to, among other things, add section 301(ll) of the FD&C Act (21 U.S.C. 331(ll)). Section 301(ll) of the FD&C Act prohibits the introduction or delivery for introduction into interstate commerce of any food that contains a drug approved under section 505 of the FD&C Act (21 U.S.C. 355), a biological product licensed under section 351 of the Public Health Service Act (42 U.S.C. 262), or a drug or biological product for which substantial clinical investigations have been instituted and their existence has been made public, unless one of the exceptions in section 301(ll)(1) to (ll)(4) of the FD&C Act applies. In our review of this petition, we did not consider whether section 301(ll) of the FD&C Act or any of its exemptions apply to food containing these additives. Accordingly, this final rule should not be construed to be a statement that a food containing these additives, if introduced or delivered for introduction into interstate commerce, would not violate section 301(ll) of the FD&C Act. Furthermore, this language is included in all food additive final rules and therefore should not be construed to be a statement of the likelihood that section 301(ll) of the FD&C Act applies.
