§ 372.65

Chemicals and chemical categories to which this part applies.

The requirements of this part apply to the chemicals and chemical categories listed in this section. This section contains six listings. Paragraph (a) of this section is an alphabetical order listing of those chemicals that have an associated Chemical Abstracts Service (CAS) Registry number. Paragraph (b) of this section contains a CAS number order list of the same chemicals listed in paragraph (a) of this section. Paragraph (c) of this section contains the chemical categories for which reporting is required. These chemical categories are listed in alphabetical order and do not have CAS numbers. Paragraph (d) of this section is an alphabetical order listing of the per- and polyfluoroalkyl substances and their associated CAS Registry number. Paragraph (e) of this ( print page 81811) section contains a CAS number order list of the same chemicals listed in paragraph (d) of this section. Each listing identifies the effective date for reporting under § 372.30. Paragraph (f) of this section is an alphabetical order listing of the per- and polyfluoroalkyl substances chemical categories for which reporting is required. Per- and polyfluoroalkyl substances automatically added to the list of chemicals for which reporting is required pursuant to the Fiscal Year 2020 National Defense Authorization Act, section 7321(c), shall be incorporated as chemical categories to include the acid and associated salts, acyl/sulfonyl halides, and anhydride of that acid if added pursuant to a published final toxicity value that provides toxicity values for an acid and associated salts and/or acyl/sulfonyl halides and/or anhydride.
