Proposed Significant New Use Rule for Multi-walled Carbon 
Nanotubes; Reopening of Comment Period

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; reopening of comment period.

-----------------------------------------------------------------------

SUMMARY: EPA issued a proposed rule in the Federal Register of February 
3, 2010, concerning a proposed significant new use rule (SNUR) for the 
chemical substance identified generically as multi-walled carbon 
nanotubes (P-08-199). In order to address public comments, EPA is 
adding information to the docket and reopening the comment period. This 
document reopens the comment period for 30 days.

DATES: Comments, identified by docket identification (ID) number EPA-
HQ-OPPT-2009-0686, must be received on or before August 27, 2010.

ADDRESSES: Follow the detailed instructions as provided under ADDRESSES 
in the Federal Register document of February 3, 2010.

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 Sec.  
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.
