EPA Proposes New SNURs for 25 Chemicals

The Environmental Protection Agency is proposing new reporting requirements for 25 chemicals under significant new use rules. The proposed SNURs would require notification to EPA at least 90 days in advance of a new use by importers, manufacturers or processors, it said in a notice published in the Oct. 31 Federal Register. Importers of chemicals subject to these proposed SNURs would need to certify their compliance with the SNUR requirements should these proposed rules be finalized, EPA said. Exporters of these chemicals would become subject to export notification requirements. Comments on the proposed SNURs are due by Nov. 30. The SNURs would cover the following chemical substances:

• Quaternary ammonium salt of polyisobutene succinic acid (generic).
• 2-Propenoic acid, 2-alkyl-, 2-(dialkylamino)alkyl ester, polymer with alpha-(2-alkyl-1-oxo-2-alken-1-yl)-omega-methoxypoly(oxy-1,2-alkanediyl) (generic).
• Alkanedioic acid, polymer with cycloalkyl dimethanol, alkyl and cycloalkyl diisocyanates, dimethyl-alkanediol, dihydroxyalkanoic acid methylenebis[isocyanatocyclohexane, hydroxyethyl acrylate- and polyalkyl glycol monoalkyl ether blocked (generic)
• Poly(oxy-1,4-butanediyl), alpha-hydro-omega-hydroxy-, polymer with 1,1′-methylenebis[4-isocyanatobenzene),caprolactam-blocked.
• Tall oil pitch, fraction, sterol-low (generic).
