The EPA on Friday, Sept. 18, 2009, promulgated significant new use rules (SNURs) for 12 chemical substances which were the subject of premanufacture notices (PMNs). Two of these chemical substances are subject to TSCA section 5(e) consent orders issued by the agency.

The chemicals are as follows (CAS numbers noted where available):

1. Benzeneethanol,halo-,halocycloalkyl-,hydrazinealkyl-(generic)
2. 2-Pentanone, 3,5-dichloro-(CAS number: 58371-98-5)
3. 1-Docosanamine, N,N-dimethyl- (CAS number: 21542-96-1)
4. Poly(oxy-1,2-ethanediyl), .alpha.-[(13Z)-1-oxo-13-docosen-1-yl]-.omega.-[[(13Z)-1-oxo-13-docosen-1-yl]oxy]- (CAS number: 56565-72-1)
5. Substituted silyl methacrylate (generic).
6. 1,3 Dioxolane-4-butanol, 2-ethenyl- (CAS number: 2421-08-1)
7. Chloro fluoro alkane (generic).
8. Benzenecarboximidamide, N-hydroxy-4-nitro- (CAS number: 1613-86-1)
9. Carbonotrithioic acid, bis(phenylmethyl) ester (CAS number: 26504-29-0)
10. 1,3-Cyclohexanedione, 2-[2-chloro-4-(methylsulfonyl)-3-[(2,2,2-trifluoroethoxy)methyl]benzoyl]-, ion(1-), potassium salt (1:1) (CAS number: 1121649-70-4)
11. Tetrafluoro nitrotoluene (generic)
12. Cesium tungsten oxide (CAS number: 52350-17-1)

This action requires persons who intend to manufacture, import, or process any of these 12 chemical substances for an activity that is designated as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The agency said in the Federal Register that the required notification will provide agency personnel with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.

The effective date of this rule is Nov. 17, 2009 without further notice, unless the agency receives written adverse or critical comments, or notice of intent to submit adverse or critical comments before Oct. 19, 2009.
