On April 30, 2020, in a Federal Register Notice (FRN), the Environmental Protection Agency (EPA) proposed significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for three chemicals. This would require notifying the EPA at least 90 days before beginning any manufacturing or processing for the SNUR. Comments on the proposed SNURs are due May 30, 2021.
The affected chemicals are:
- Heptanal, 6-hydroxy-2,6-dimethyl-;
- Glycine, reaction products with sodium O-iso-Pr carbonodithioate, sodium salts; and
- Alkanedioic acid, polymer with tri-alkyl-isocyanatocarbomonocycle, dialkylglycols, ester with 2,3-dihydroxypropyl alkyl ester, 2-hydroxyethyl methacrylate-blocked (generic).
In a second FRN, the EPA issued SNURs for two chemicals and one microorganism. The rule will be effective on June 29, 2021.
The affected substances are:
- 1-Propanaminium, N-(carboxymethyl)-N,N-dimethyl-3-[(3,5,5-trimethyl1-oxohexyl)amino]-, inner salt;
- 2-propenoic acid, 2-methyl-, (2-oxo-1,3-dioxolan-4-yl)methyl ester; and
- Trichoderma reesei (generic).
