710.46—Chemical substances for which information is not required.
The following groups or categories of chemical substances are exempted from some or all of the reporting requirements of this subpart, with the following exception: A chemical substance described in paragraph (a)(1), (a)(2), or (a)(4), or (b) of this section is not exempted from any of the reporting requirements of this subpart if that substance is the subject of a rule proposed or promulgated under section 4, 5(a)(2), 5(b)(4), or 6 of the Act, or is the subject of an order issued under section 5(e) or 5(f) of the Act, or is the subject of relief that has been granted under a civil action under section 5 or 7 of the Act.
(a) Full exemptions.
The following categories of chemical substances are exempted from the reporting requirements of this subpart.
(1) Polymers.
(i)
Any chemical substance described with the word fragments “*polym*”, “*alkyd”, or “*oxylated” in the Chemical Abstracts Service Index or Preferred Nomenclature in the Chemical Substance Identities section of the Master Inventory File, where the asterisk (*) indicates that any sets of characters may precede, or follow, the character string defined.
(ii)
Any chemical substance which is identified in the Master Inventory File as siloxane and silicone, silsesquioxane, a protein (albumin, casein, gelatin, gluten, hemoglobin), an enzyme, a polysaccharide (starch, cellulose, gum), rubber, or lignin.
(iii)
This exclusion does not apply to a polymeric substance that has been hydrolyzed, depolymerized, or otherwise chemically modified, except in cases where the intended product of this reaction is totally polymeric in structure.
(2) Microorganisms.
Any combination of chemical substances that is a living organism, and that meets the definition of “microorganism” at § 725.3 of this chapter. Any chemical substance produced from a living microorganism is reportable under this subpart unless otherwise excluded.
(3) Naturally occurring chemical substances.
Any naturally occurring chemical substance, as described in § 710.4(b). The applicability of this exclusion is determined in each case by the specific activities of the person who manufactures the substance in question. Some chemical substances can be manufactured both as described in § 710.4(b) and by means other than those described in § 710.4(b). If a person described in § 710.48 manufactures a chemical substance by means other than those described in § 710.4(b), the person must report regardless of whether the substance also could have been produced as described in § 710.4(b). Any chemical substance that is produced from such a naturally occurring chemical substance described in § 710.4(b) is reportable unless otherwise excluded.
(4) Certain forms of natural gas.
Chemical substances with the following Chemical Abstract Service (CAS) Registry Numbers: CAS No. 64741-48-6, Natural gas (petroleum), raw liquid mix; CAS No. 68919-39-1, Natural gas condensates; CAS No. 8006-61-9, Gasoline natural; CAS No. 68425-31-0, Gasoline (natural gas), natural; CAS No. 8006-14-2, Natural gas; and CAS No. 68410-63-9, Natural gas, dried.
(b) Partial exemptions.
The following groups of chemical substances are partially exempted from the reporting requirements of this subpart (i.e., the information described in § 710.52(c)(4) need not be reported for these substances). Such chemical substances are not excluded from the other reporting requirements under this subpart. A chemical substance described in paragraph (b)(3) of this section qualifies for a partial reporting exemption during the 2006 submission period; in subsequent submission periods, the chemical substances described in paragraph (b)(3) of this section will be subject to full reporting under this subpart (i.e., all of the information described in this subpart must be reported), unless otherwise exempted.
(1) Petroleum process streams.
