SUPPLEMENTARY INFORMATION : 
I. Introduction 
In a notice published in the Federal 
Register of December 13, 2018 (83 FR 
64045), we announced that we filed a color additive petition (CAP 9C0314) submitted by Impossible Foods, Inc., c/o Exponent, Inc., 1150 Connecticut Avenue NW, Suite 1100, Washington, DC 20036. The petition proposed to amend the color additive regulations in part 73 (21 CFR part 73), ‘‘Listing of Color Additives Exempt from Certification’’ to provide for the safe use of soy leghemoglobin as a color additive in ground beef analogue products such that the amount of soy leghemoglobin protein does not exceed 0.8 percent by weight of the uncooked ground beef analogue product. For the purposes of this final rule, the term ‘‘ground beef analogue products’’ refers to plant-based or other non-animal derived ground beef-like food products. The petition describes soy leghemoglobin protein as the principal reddish brown coloring component of a stabilized mixture, referred to as soy leghemoglobin preparation. We are establishing soy leghemoglobin as the common or usual name for this color additive and note 
VerDate Sep<11>2014 16:12 Jul 31, 2019 Jkt 247001 PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 E:\FR\FM\01AUR1.SGM 01AUR1jspears on DSK3GMQ082PROD with RULES37574 Federal Register / Vol. 84, No. 148 / Thursday, August 1, 2019 / Rules and Regulations 
that the terms ‘‘soy leghemoglobin’’ and 
‘‘soy leghemoglobin preparation’’ are used interchangeably when referring to the name of the color additive in this final rule and in our review memoranda (Refs. 1 and 2). 
II. Background 
The color additive that is the subject 
of this petition is the stabilized product 
of controlled fermentation of a non- pathogenic and non-toxicogenic strain of the yeast, Pichia pastoris (P. pastoris), genetically engineered to express soy leghemoglobin protein, the principal coloring component. Soy leghemoglobin gets its name from its source, the soybean root; it is a hemeprotein present in the nitrogen-fixing root nodules of leguminous plants. The color additive is manufactured by construction of the P. pastoris production strain, expression of 
soy leghemoglobin protein via fermentation, followed by concentration and stabilization of the expressed protein. Based on information in the petition, soy leghemoglobin preparation contains not more than 9 percent soy leghemoglobin protein, minor quantities of P. pastoris yeast proteins, and 
optional stabilizers sodium chloride and sodium ascorbate. The color additive is stored either as a frozen liquid or in a spray dried form. FDA concurs with the petitioner that the genetic modifications made to generate the non-toxigenic and non-pathogenic production strain are well-characterized and the production process conforms to good manufacturing practice (Ref. 1). In addition to specification limits for lead, arsenic, mercury, and cadmium, we are requiring a specification for the minimum purity of soy leghemoglobin protein as a percent of the total protein in the color additive. 
We have previously considered the 
safety of soy leghemoglobin preparation as the result of a submission from Impossible Foods who made its own determination, to which we had no questions, that the use of soy leghemoglobin preparation to optimize flavor in ground beef analogue products intended to be cooked is generally recognized as safe (GRAS). Under section 201(s) of the Federal Food, Drug, 
and Cosmetic Act (FD&C Act) (21 U.S.C. 321(s)), a substance is GRAS if it is generally recognized, among experts qualified by scientific training and experience to evaluate its safety, as having been adequately shown through scientific procedures (or, in the case of a substance used in food before January 1, 1958, through either scientific procedures or experience based on common use in food) to be safe under the conditions of its intended use. Under section 201(s) of the FD&C Act, 
a substance that is GRAS for a particular use in food is not a food additive and may lawfully be utilized for that use without our review and approval. There is no GRAS exemption, however, to the definition of a color additive in section 201(t) of the FD&C Act. Therefore, we must approve the use of a color additive in food before it is marketed; otherwise, the food containing the color additive is adulterated under section 402(c) of the FD&C Act (21 U.S.C. 342(c)). 
A firm may voluntarily submit to FDA 
information supporting the firm’s own conclusion that a substance is GRAS for its intended use in food through our GRAS notification program (see 81 FR 54960 (August 17, 2016)). Through this program, a GRAS notification (GRN) was submitted on behalf of Impossible Foods on October 3, 2017 (GRN 737). This GRN informed FDA that Impossible Foods concluded that the use of soy leghemoglobin preparation to deliver up to 0.8 percent soy leghemoglobin protein by weight in the final food was GRAS for optimizing flavor in ground beef analogue products intended to be cooked. Based on our evaluation of the information provided in GRN 737, as well as other available information, we issued a letter on July 23, 2018, to Impossible Foods stating that we had no questions regarding its conclusion that soy leghemoglobin preparation is GRAS for its intended conditions of use. 
Importantly, in our response letter to 
Impossible Foods, we stated that because soy leghemoglobin preparation is reddish-brown, its use may constitute a color additive use under section 201(t)(1) of the FD&C Act and FDA’s implementing regulations in 21 CFR part 70. In the case of the soy leghemoglobin preparation, the reddish color imparted to the uncooked ground beef analogue product is lost when the product is heated, and the soy leghemoglobin protein responsible for imparting the reddish color in the food is denatured by the cooking process. Impossible Foods’ GRAS conclusion in GRN 737 was for the use of soy leghemoglobin preparation to optimize flavor in ground beef analogue products intended to be cooked. When soy leghemoglobin preparation is used in ground beef analogue products sold directly to consumers in an uncooked form, the reddish color imparted by the soy leghemoglobin preparation gives the appearance of uncooked ground beef to the ground beef analogue product. This specific use of soy leghemoglobin preparation to impart a reddish color to 
a food is important to the appearance and marketability of the food. Therefore, FDA determined that this use of soy leghemoglobin preparation requires premarket approval as a color additive (see § 70.3(g) (21 CFR 70.3(g))). 
III. Safety Evaluation 
Under section 721(b)(4) of the FD&C 
Act (21 U.S.C. 379e(b)(4)), a color 
additive may not be listed for a proposed use unless the data and information available to FDA establish that the color additive is safe for that use. Our color additive regulations at § 70.3(i) define ‘‘safe’’ to mean that there is convincing evidence establishing with reasonable certainty that no harm will result from the intended use of the color additive. 
As part of our safety evaluation to 
establish with reasonable certainty that a color additive is not harmful under its intended conditions of use, we consider the additive’s manufacturing and stability; the projected human dietary exposure to the additive and any impurities resulting from the petitioned use of the additive; the additive’s toxicological data; and other relevant information (such as published literature) available to us. 
IV. Safety of Petitioned Use of the Color 
Additive 
A. Exposure Estimate 
Soy leghemoglobin preparation is 
composed mainly of soy leghemoglobin 
protein, minor quantities of P. pastoris proteins, water, fat, carbohydrates, and any stabilizers that are used. During our safety review of this petition (CAP 9C0314), we evaluated the petitioner’s dietary exposure estimates for the soy leghemoglobin preparation and for the soy leghemoglobin protein component of the preparation. To estimate dietary exposure, the petitioner used nationwide ground beef consumption data collected from 2003 to 2014 as part of the National Health and Nutrition Examination Survey and assumed a 1- to-1 substitution of conventional ground beef with ground beef analogue product containing soy leghemoglobin preparation at its maximum use level. The petitioner estimated the dietary exposure to soy leghemoglobin preparation for the U.S. population (aged 2 years or more) to be 3,556 milligrams/person/day (mg/p/d) at the mean and 7,911 mg/p/d at the 90th percentile. For soy leghemoglobin protein only, the estimated dietary exposure for the U.S population was 320 mg/p/d at the mean and 712 mg/p/ d at the 90th percentile. FDA confirmed the petitioner’s exposure estimates for soy leghemoglobin protein and soy leghemoglobin preparation and notes 
VerDate Sep<11>2014 16:12 Jul 31, 2019 Jkt 247001 PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 E:\FR\FM\01AUR1.SGM 01AUR1jspears on DSK3GMQ082PROD with RULES37575 Federal Register / Vol. 84, No. 148 / Thursday, August 1, 2019 / Rules and Regulations 
that the estimates assume that all 
conventional ground beef and ground beef-containing foods are replaced with ground beef analogue product (Ref. 1). FDA estimated the dietary exposure to total protein (soy leghemoglobin protein plus P. pastoris proteins) from the 
petitioned use of the color additive to be 871 mg/p/d (Ref. 1). We also considered U.S. consumers’ dietary exposure to iron from the petitioned use of the color additive and determined that no significant change in exposure to dietary iron would occur since the amount of iron from the petitioned use of soy leghemoglobin in ground beef analogue products is similar to the amount of iron found in traditional ground beef (Ref. 1). 
B. Toxicological Considerations 
To establish that soy leghemoglobin is 
safe for use as a color additive that 
provides up to 0.8 percent soy leghemoglobin protein in ground beef analogue products, the petitioner used a weight-of-evidence approach based on: (1) The history of consumption of soy, soy leghemoglobin protein, and P. pastoris; (2) the safety of P. pastoris as 
a production strain; (3) 14-day and 28- day feeding studies with soy leghemoglobin preparation in rats; (4) mutagenicity and genotoxicity studies of soy leghemoglobin preparation; and (5) an allergenicity assessment of soy leghemoglobin and P. pastoris proteins in the soy leghemoglobin preparation. 
Based on our review of this petition 
(CAP 9C0314), we conclude that the proteins in the soy leghemoglobin preparation are well defined, non-toxic, and that the contribution of total proteins (soy leghemoglobin protein plus P. pastoris proteins) from the 
petitioned use of the color additive to total daily dietary protein would be only 1.7 percent, assuming a daily dietary intake of 50 grams of protein per person per day (Ref. 2). Regarding the P. 
pastoris strain developed by the 
petitioner for the production of soy leghemoglobin preparation, we conclude that it is non-toxicogenic and non-pathogenic. We evaluated the results from the 14-day dose range finding study and two 28-day toxicity studies in rats fed soy leghemoglobin preparation and conclude that they did not show any toxicologically relevant effects. We also determined that the mutagenicity and genotoxicity studies provided in the petition showed no evidence of mutagenic activity or increased chromosomal aberrations in cells exposed to soy leghemoglobin preparation. 
To address the allergenicity potential 
of soy leghemoglobin preparation, the petition provided results from a study on the digestibility of soy 
leghemoglobin preparation, bioinformatic analyses of soy leghemoglobin protein and of P. pastoris proteins identified in the soy leghemoglobin preparation, and a memorandum from an expert in the field of food allergies on the potential allergenicity of soy leghemoglobin. We conclude that soy leghemoglobin and P. pastoris proteins in the soy 
leghemoglobin preparation are readily digested at acidic pH conditions found in the stomach and denatured at normal cooking temperatures. We also agree with the petitioner that the totality of evidence supports the conclusion that soy leghemoglobin protein and P. pastoris proteins present in soy 
leghemoglobin preparation do not pose risks of allergenicity when consumed, 
even for people who are allergic to foods containing soybean protein (Ref. 2). 
V. Conclusion 
Based on the data and information in 
the petition and other available relevant 
information, we conclude that the petitioned use of soy leghemoglobin as a color additive in ground beef analogue products is safe, provided the amount of soy leghemoglobin protein does not exceed 0.8 percent by weight of the uncooked product. We further conclude that this color additive will achieve its intended technical effect and is suitable for the petitioned use. Therefore, we are amending the color additive regulations in part 73 to provide for the safe use of this color additive as set forth in this document. In addition, based on the factors in 21 CFR 71.20(b), we conclude that batch certification of soy leghemoglobin is not necessary to protect the public health. 
VI. Public Disclosure 
In accordance with § 71.15(a) (21 CFR 
71.15(a)), 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 
ADDRESSES ). As provided in § 71.15(b), 
we will delete from the documents any materials that are not available for public disclosure. 
VII. Analysis of Environmental Impact 
As stated in the December 13, 2018, 
Federal Register notice of filing, the 
petitioner claimed that this action is categorically excluded under § 25.32(k) (21 CFR 25.32(k)) because soy leghemoglobin would be added directly to food and is intended to remain in the food through ingestion by consumers and is not intended to replace macronutrients in food. We further stated that if FDA determines a 
categorical exclusion applies, neither an environmental assessment nor an environmental impact statement is required. We have not received any new information or comments regarding this claim of categorical exclusion. We have considered the petitioner’s claim of categorical exclusion and have determined that this action is categorically excluded under § 25.32(k). Therefore, neither an environmental assessment nor an environmental impact statement is required. 
VIII. 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. 
IX. Section 301(ll) of the FD&C Act 
Our review of this petition was 
limited to section 721 of the FD&C Act. 
This final rule is not a statement regarding compliance with other 
sections of the FD&C Act. For example, 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 exemptions in section 301(ll)(1) to (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 this color additive. Accordingly, this final rule should not be construed to be a statement that a food containing this color additive, 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 color additive final rules that pertain to food and therefore should not be construed to be a statement of the likelihood that section 301(ll) of the FD&C Act applies. 
X. Objections 
This rule is effective as shown in the 
DATES section, except as to any 
provisions that may be stayed by the 
filing of proper objections. If you will be adversely affected by one or more provisions of this regulation, you may file with the Dockets Management Staff (see

SUPPLEMENTARY INFORMATION : 
Background 
Section 508 authorizes the Access 
Board to establish standards for technical and functional performance criteria to ensure that information technologies are accessible to and usable by persons with disabilities. The Department published its initial rules implementing Section 508 of the Rehabilitation Act of 1973, 29 U.S.C. 794d (Section 508), in 2016. 81 FR 32645. 
In January of 2017, the Access Board 
published a ‘‘refresh’’ of its existing standards and guidelines for information and communication technology (ICT) covered by Section 508 of the Rehabilitation Act or Section 255 of the Communications Act. The rule jointly updated and reorganized the Section 508 standards and Section 255 guidelines to advance accessibility, facilitate compliance, and harmonize the requirements with other standards in the United States and abroad. 82 FR 5832. Federal agencies, however, need only comply with the revised 508 standards (codified at 38 CFR 1194.1 and Appendices A, C, and D), whereas the revised Section 255 guidelines apply exclusively to telecommunications equipment manufacturers. 
Proposed Rule and Comments 
On December 13, 2018, the 
Department published its proposed rule 
to implement the refreshed Section 508 standards. 83 FR 64046. The Department received five comments in response to the proposed rule, all supportive. Four of the five commenters asserted that the burden or impact on
