Start Preamble

AGENCY:

Food and Drug Administration, HHS.

ACTION:

Final rule.

SUMMARY:

The Food and Drug Administration (FDA) is amending the food additive regulations to provide for the safe use of methyltin-2-mercaptoethyloleate sulfide used alone or in combination with several optional substances as a heat stabilizer for use in rigid poly(vinyl chloride) (PVC) and rigid vinyl chloride copolymers intended for use in the manufacture of pipes and pipe fittings that will contact water in food processing plants. This action is in response to a petition filed by Morton International, Inc.

DATES:

This rule is effective March 23, 2000. Submit written objections and requests for a hearing by April 24, 2000.

ADDRESSES:

Submit written objections to the Dockets Management Branch (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852.

SUPPLEMENTARY INFORMATION:

In a notice published in the Federal Register of October 21, 1994 (59 FR 53193), FDA announced that a food additive petition (FAP 4B4430) had been filed by Morton International, Inc., 2000 West St., Cincinnati, OH 45215. The petition proposed to amend the food additive regulations in § 178.2010 Antioxidants and/or stabilizers for polymers (21 CFR 178.2010) to provide for the safe use of methyltin-2-mercaptoethyloleate sulfide mixtures as heat stabilizers for use in PVC pipes intended for transporting water for food contact.

Subsequent to the filing of the petition, FDA determined that methyltin-2-mercaptoethyloleate sulfide is a complex mixture. In addition, FDA determined that the petition also proposed that methyltin-2-mercaptoethyloleate sulfide may be used in combination with certain optional substances. Therefore, in a notice published in the Federal Register of September 7, 1999 (64 FR 48655), FDA announced that it was amending the filing notice of October 21, 1994, to indicate that the petitioner requests that the food additive regulations be amended to provide for the safe use of methyltin-2-mercaptoethyloleate sulfide as a heat stabilizer for use in rigid PVC and rigid vinyl chloride copolymers, complying with §§ 177.1950 and 177.1980 (21 CFR 177.1950 and 177.1980), respectively, intended for use in the manufacture of pipes and pipe fittings that will contact water in food processing plants. For these purposes, methyltin-2-mercaptoethyloleate sulfide is defined as one or more of the following:

1. 9-Octadecenoic acid (Z)-, 2-mercaptoethyl ester, reaction products with dichlorodimethylstannane, sodium sulfide, and trichloromethylstannane (CAS Reg. No. 68442-12-6); or

2. Fatty acids, tall oil, 2-mercaptoethyl esters, reaction products with dichlorodimethylstannane, 2-mercaptoethyl decanoate, 2-mercaptoethyl octanoate, sodium sulfide, and trichloromethylstannane (CAS Reg. No. 151436-98-5); or

3. Fatty acids, tall oil, 2-mercaptoethyl esters, reaction products with dichlorodimethylstannane, sodium sulfide, and trichloromethylstannane (CAS Reg. No. 201687-57-2).

In addition, FDA announced in the September 7, 1999, notice that it was amending the filing notice of October 21, 1994, to indicate that the petitioner requested that the food additive regulations be amended to provide for the safe use of methyltin-2-mercaptoethyloleate sulfide as a heat stabilizer for use in rigid PVC and rigid vinyl chloride copolymers, complying with §§ 177.1950 and 177.1980, respectively, intended for use in the manufacture of pipes and pipe fittings that will contact water in food processing plants, in combination with the following optional substances:

1. 2-Mercaptoethyl oleate (CAS Reg. No. 59118-78-4), or 2-mercaptoethyl tallate (CAS Reg. No. 68440-24-4), or 2-mercaptoethyl octanoate (CAS Reg. No. 57813-59-9), or 2-mercaptoethyl decanoate (CAS Reg. No. 68928-33-6), alone or in combination;

2. 2-Mercaptoethanol (CAS Reg. No. 60-24-2);

3. Mineral oil (CAS Reg. No. 8012-95-1); or

4. Butylated hydroxytoluene (CAS Reg. No. 128-37-0).

FDA has evaluated the data in the petition and other relevant material. Based on this information, the agency concludes that: (1) The proposed use of the additive is safe, (2) the additive will achieve its intended technical effect, and (3) the regulations in 21 CFR 178.2010 should be amended as set forth below.

In accordance with § 171.1(h) (21 CFR 171.1(h)), the petition and the documents that FDA considered and relied upon in reaching its decision to approve the petition are available for inspection at the Center for Food Safety and Applied Nutrition by appointment with the information contact person listed above. As provided in § 171.1(h), the agency will delete from the documents any materials that are not available for public disclosure before making the documents available for inspection.

The agency has previously considered the environmental effects of this rule as announced in the notice of filing for FAP 4B4430 (64 FR 48655). No new information or comments have been received that would affect the agency's previous determination that there is no significant impact on the human environment and that an environmental impact statement is not required.

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.

Any person who will be adversely affected by this regulation may at any time file with the Dockets Management Branch (address above) written objections by April 24, 2000. Each objection shall be separately numbered, and each numbered objection shall specify with particularity the provisions of the regulation to which objection is made and the grounds for the objection. Each numbered objection on which a hearing is requested shall specifically so state. Failure to request a hearing for any particular objection shall constitute a waiver of the right to a hearing on that objection. Each numbered objection for which a hearing is requested shall include a detailed description and analysis of the specific factual information intended to be presented in support of the objection in the event that a hearing is held. Failure to include such a description and analysis for any particular objection shall constitute a waiver of the right to a hearing on the objection. Three copies of all documents shall be submitted and shall be identified 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 Dockets Management Branch between 9 a.m. and 4 p.m., Monday through Friday.
