FOI Summary. 53310 Federal Register / Vol. 84, No. 194 / Monday, October 7, 2019 / Rules and Regulations II. Change of Sponsor’s Names and Addresses Medicis Dermatologics, Inc., 8125 North Hayden Rd., Scottsdale, AZ 85258 has informed FDA that it has changed its name and address to Bausch Health US, LLC, 400 Somerset Corporate Blvd., Bridgewater, NJ 08807. Accordingly, we are amending § 510.600(c) to reflect these changes. III. Technical Amendments A section describing tolerances of hetacillin residues (21 CFR 556.316) has been added to subpart B of part 556. This section cross-references the sole hetacillin product approved for use in food-producing animals, an intramammary infusion for use in lactating dairy cows (21 CFR 526.1130). This new section codifies FDA’s finding at the time of product approval that, because hetacillin is rapidly hydrolyzed to ampicillin, existing ampicillin tolerances provide appropriate tolerances for hetacillin in edible tissues of cattle (38 FR 31172, November 12, 1973). This amendment is being made to make the regulations more comprehensive. FDA is also revising the regulations to reflect the approved conditions of use of sulfaquinoxaline soluble powder as a veterinary prescription product for oral administration to cattle as a drench. Finally, we are also revising the regulations for use of monensin in medicated goat feed to reflect the approved incorporation level. These actions are being taken to improve the accuracy of the regulations. 21 CFR Parts 520, 522, 526, and 529 IV. Legal Authority This final rule is issued under section 512(i) of the Federal Food, Drug, and Cosmetic Act (the FD&C Act) (21 U.S.C. 360b(i)), which requires Federal Register publication of ‘‘notice[s] . . . effective as a regulation,’’ of the conditions of use of approved new animal drugs. This rule sets forth technical amendments to the regulations to codify recent actions on approved new animal drug applications and corrections to improve the accuracy of the regulations, and as such does not impose any burden on regulated entities. Although denominated a rule pursuant to the FD&C Act, this document does not meet the definition of ‘‘rule’’ in 5 U.S.C. 804(3)(A) because it is a ‘‘rule of particular applicability.’’ Therefore, it is not subject to the congressional review requirements in 5 U.S.C. 801–808. Likewise, this is not a rule subject to Executive Order 12866, which defines a rule as ‘‘an agency statement of general applicability and future effect, which the agency intends to have the force and effect of law, that is designed to implement, interpret, or prescribe law or policy or to describe the procedure or practice requirements of an agency.’’ List of Subjects Animal drugs. 21 CFR Part 556 Animal drugs, Foods. 21 CFR Part 558 Animal drugs, Animal feeds. Therefore, under the Federal Food, Drug, and Cosmetic Act and under authority delegated to the Commissioner of Food and Drugs, 21 CFR parts 510, 520, 522, 526, 529, 556, and 558 are amended as follows: PART 510—NEW ANIMAL DRUGS 1.

II. Change of Sponsor's Names and Addresses

    Medicis Dermatologics, Inc., 8125 North Hayden Rd., Scottsdale, AZ 
85258 has informed FDA that it has changed its name and address to 
Bausch Health US, LLC, 400 Somerset Corporate Blvd., Bridgewater, NJ 
08807. Accordingly, we are amending Sec.  510.600(c) to reflect these 
changes.

III. Technical Amendments

    A section describing tolerances of hetacillin residues (21 CFR 
556.316) has been added to subpart B of part 556. This section cross-
references the sole hetacillin product approved for use in food-
producing animals, an intramammary infusion for use in lactating dairy 
cows (21 CFR 526.1130). This new section codifies FDA's finding at the 
time of product approval that, because hetacillin is rapidly hydrolyzed 
to ampicillin, existing ampicillin tolerances provide appropriate 
tolerances for hetacillin in edible tissues of cattle (38 FR 31172, 
November 12, 1973). This amendment is being made to make the 
regulations more comprehensive.
    FDA is also revising the regulations to reflect the approved 
conditions of use of sulfaquinoxaline soluble powder as a veterinary 
prescription product for oral administration to cattle as a drench. 
Finally, we are also revising the regulations for use of monensin in 
medicated goat feed to reflect the approved incorporation level. These 
actions are being taken to improve the accuracy of the regulations.

IV. Legal Authority

    This final rule is issued under section 512(i) of the Federal Food, 
Drug, and Cosmetic Act (the FD&C Act) (21 U.S.C. 360b(i)), which 
requires Federal Register publication of ``notice[s] . . . effective as 
a regulation,'' of the conditions of use of approved new animal drugs. 
This rule sets forth technical amendments to the regulations to codify 
recent actions on approved new animal drug applications and corrections 
to improve the accuracy of the regulations, and as such does not impose 
any burden on regulated entities.
    Although denominated a rule pursuant to the FD&C Act, this document 
does not meet the definition of ``rule'' in 5 U.S.C. 804(3)(A) because 
it is a ``rule of particular applicability.'' Therefore, it is not 
subject to the congressional review requirements in 5 U.S.C. 801-808. 
Likewise, this is not a rule subject to Executive Order 12866, which 
defines a rule as ``an agency statement of general applicability and 
future effect, which the agency intends to have the force and effect of 
law, that is designed to implement, interpret, or prescribe law or 
policy or to describe the procedure or practice requirements of an 
agency.''

List of Subjects

21 CFR Part 510

    Administrative practice and procedure, Animal drugs, Labeling, 
Reporting and recordkeeping requirements.

21 CFR Parts 520, 522, 526, and 529

    Animal drugs.

21 CFR Part 556

    Animal drugs, Foods.

21 CFR Part 558

    Animal drugs, Animal feeds.

    Therefore, under the Federal Food, Drug, and Cosmetic Act and under 
authority delegated to the Commissioner of Food and Drugs, 21 CFR parts 
510, 520, 522, 526, 529, 556, and 558 are amended as follows:
