         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 766_DIBENZO-PARA-DIOXINS/DIBENZOFURANS--Table of Contents
 
       Subpart B_Specific Chemical Testing/Reporting Requirements
 
Sec. 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.

    (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.
