Title 40: Protection of Environment
PART 766—DIBENZO-PARA-DIOXINS/DIBENZOFURANS
Subpart B—Specific Chemical Testing/Reporting Requirements


§766.25   Chemical substances for testing.

(a) Listing of chemical substances. Chemical substances required to be tested for HDDs/HDFs under this rule are listed in this section. The listing is by Chemical Abstracts Service (CAS) Number and common name.

Note: For purposes of guidance only, EPA lists the chemical substances subject to testing under this part in two classes—those known to be manufactured or imported between January 1, 1984, and promulgation of this part, and those not known to be manufactured or imported at the time of promulgation of this part.

(1) Chemicals substances known to be manufactured between January 1, 1984 and date of promulgation of this part.

CAS No. Chemical name
79-94-7Tetrabromobisphenol-A.
118-75-22,3,5,6-Tetrachloro-2,5-cyclohexadiene-1,4-dione.
118-79-62,4,6-Tribromophenol.
120-83-22,4-Dichlorophenol.
1163-19-5Decabromodiphenyloxide.
4162-45-2Tetrabromobisphenol-A-bisethoxylate.
21850-44-2Tetrabromobisphenol-A-bis-2,3-dibromopropyl ether.
25327-89-3Allyl ether of tetrabromobisphenol-A.

37853-59-11,2-Bis(tribromophenoxy)-ethane.
55205-38-4Tetrabromobisphenol-A diacrylate.

(2) Chemicals not known to be manufactured between January 1, 1984 and the date of promulgation of this part.

CAS No. Chemical name
79-95-8Tetrachlorobisphenol-A.
87-10-53,4′,5-Tribromosalicylanilide.
87-65-02,6-Dichlorophenol.
95-77-23,4-Dichlorophenol.
95-95-42,4,5-Trichlorophenol.
99-28-52,6-Dibromo-4-nitrophenol.

320-72-93,5-Dichlorosalicyclic acid.
488-47-1Tetrabromocatechol.
576-24-92,3-Dichlorophenol.
583-78-82,5-Dichlorophenol.
608-71-9Pentabromophenol.
615-58-72,4-Dibromophenol.
933-75-52,3,6-Trichlorophenol.
1940-42-74-Bromo-2,5-dichlorophenol.
2577-72-23,5-Dibromosalicylanilide.
3772-94-9Pentachlorophenyl laurate.
37853-61-5Bismethylether of tetrabromobisphenol-A.
   Alkylamine tetrachlorophenate.
   Tetrabromobisphenol-B.

(b) Grade to be tested. If the same process is used to manufacture all grades of the same chemical substance, only one grade need be tested. The grade to be tested must be the grade subject to the most intense heat and alkalinity for the longest duration of time, manufactured under each different process. If the heat, alkalinity and duration of reaction do not differ for various grades, the test substance must be the grade of chemical substance with the highest volume of sales.
