Sec. 766.38  Reporting on precursor chemical substances.

    (a) Identification of precursor chemical substances. Precursor 
chemical substances are produced under conditions that will not yield 
HDDs and HDFs, but their molecular structure is conducive to HDD/HDF 
formation under favorable reaction conditions when they are used to 
produce other chemicals or products. The following precursor chemical 
substances are identified by Chemical Abstract Service (CAS) number and 
name.

    (b) Persons required to report. All persons who manufacture or 
import a chemical product produced using any of the chemical substances 
listed in paragraph (a) of this section as feedstocks or intermediates 
must report no later than September 29, 1987. Small manufacturers and 
those manufacturers and importers who produce the precursor chemical 
substances in quantities of 100 kilograms or less per year only for 
research and development purposes are not required to report under this 
section
    (c) Data to be reported. Manufacturers and importers of chemical 
products made from precursor chemical substances identified in paragraph 
(a) of this section must report process and reaction condition data on 
Part II of EPA Form 7710-51 for each chemical product. A separate EPA 
Form 7710-51 must be submitted for each chemical product reported, and 
the precursor chemical substance used must be identified. All forms must 
be submitted to EPA no later than September 29, 1987.
