There’s now an extension of time allotted for comments on glymes.

In July, the US Environmental Protection Agency (EPA) issued a proposed rule in the Federal Register concerning a proposed significant new use rule (SNUR) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for 14 glymes.

EPA’s list of 14 glymes is here for view or download, in an article written by one of the preeminent Professional Chemical Engineers in the field, Kal Kawar.  The article is called “The Worst of Glymes” (who says chemists can’t be funny?).  This list is easier to read than anything on the EPA site.

Since publication of the proposed rule, EPA has received a request for additional time to submit comments. Now, EPA will extend the comment period for 30 days, from September 12, 2011 to October 12, 2011.

Deadlines for comment: Comments, identified by docket identification (ID) number EPA–HQ–OPPT–2009–0767, must be received on or before October 12, 2011.

In the Federal Register of July 12, 2011 (76 FR 40850) (FRL–8877–8), EPA proposed a SNUR for 14 glymes, designated proposed significant new uses for the 14 glymes, and asked for public comment on several topics. EPA requested comment on whether any of the chemical substances included in the identified glyme category are sufficiently dissimilar from the rest such that they should be removed from the category, or whether any additional chemical substances are sufficiently similar such that they should be added to the category. Comments were also requested on whether any of the additional unconfirmed uses listed in the proposed rule are actual ongoing uses in a consumer product, and whether there are any other ongoing uses in a consumer product of the other chemicals listed in the SNUR.
