SUPPLEMENTARY INFORMATION:

This document reopens the public comment period established in the Federal Register of February 3, 2010 (75 FR 5546) (FRL-8796-7). In that document, EPA proposed a SNUR for the chemical substance identified generically as multi-walled carbon nanotubes as identified in Premanufacture Notice (PMN) P-08-199. EPA received several comments in response to the proposed SNUR. EPA will address those comments when it issues the final SNUR. One commenter noted that neither the proposed rule nor the docket contained specific carbon nanotube data or data supporting the nature of the dermal concern for carbon nanotubes. That commenter stated it was not possible to assess the Agency's evaluation and determination under § 721.170(b)(3)(ii) based on the current record. Another commenter noted that EPA's subsequent reviews and concerns for carbon nanotubes have expanded and that the proposed SNUR should reflect those updated data. EPA has added additional explanation and references of its health and environmental concerns for carbon nanotubes to the public docket for consideration. EPA is hereby reopening the comment period for 30 days to allow for any public comments in response to this additional data.

To submit comments, or access the docket, please follow the detailed instructions as provided under ADDRESSES in the February 3, 2010 Federal Register document. If you have questions, consult the technical person listed under FOR FURTHER INFORMATION CONTACT.
