Title 40Chapter ISubchapter RPart 721Subpart E → §721.10630


Title 40: Protection of Environment
PART 721—SIGNIFICANT NEW USES OF CHEMICAL SUBSTANCES
Subpart E—Significant New Uses for Specific Chemical Substances


§721.10630   Amino acid, carboxyalkyl, alkylsulfonate, alkali salt (generic).

(a) Chemical substances and significant new uses subject to reporting. (1) The chemical substances identified generically as amino acid, carboxyalkyl, alkylsulfonate, alkali salts (PMNs P-11-619 and P-11-620) are subject to reporting under this section for the significant new uses described in paragraph (a)(2) of this section.

(2) The significant new uses are:

(i) Release to water. Requirements as specified in §721.90(a)(4), (b)(4), and (c)(4) (where N = 770 parts per billion (ppb) for the aggregate of the PMN substances, P-11-619 and P-11-620). When calculating the surface water concentrations according to the instructions in §721.90(a)(4), (b)(4), and (c)(4), the statement that the amount of the substances that will be released will be calculated before the substances enter control technology does not apply. Instead, if the waste stream containing the substances will be treated before release, then the amount of the substances reasonably likely to be removed from the waste stream by such treatment may be subtracted in calculating the number of kilograms released. No more than 90 percent removal efficiency may be attributed to such treatment.

(ii) [Reserved]

(b) Specific requirements. The provisions of subpart A of this part apply to this section except as modified by this paragraph.

(1) Recordkeeping. Recordkeeping requirements as specified in §721.125(a), (b), (c), and (k) are applicable to manufacturers, importers, and processors of this substance.

(2) Limitations or revocation of certain notification requirements. The provisions of §721.185 apply to this section.
