          - 40 CFR Part 721
          - [EPA-HQ-OPPT-2011-0976; FRL-9922-45]
          - RIN 2070-AJ91

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule; extension of comment period.

# SUMMARY:

                        EPA issued a proposed rule in the                         **Federal Register**                         of January 15, 2015, concerning 2,4-toluene diisocyanate, 2,6-toluene diisocyanate, toluene diisocyanate unspecified isomers (these three chemical substances are hereafter referred to as toluene diisocyanates or TDI) and related compounds. This document extends the comment period for 45 days, from March 16, 2015, to April 30, 2015. The comment period is being extended because EPA received comments asserting that there may be significant implications for the supply chain and it is critical that interested stakeholders have sufficient time to respond to the proposed rulemaking.                    

# DATES:

The comment period for the proposed rule published on January 15, 2015 (80 FR 2068), is extended. Comments, identified by docket identification (ID) number EPA-HQ-OPPT-2011-0976, must be received on or before April 30, 2015.

# SUPPLEMENTARY INFORMATION:

                    This document extends the public comment period established in the                     **Federal Register**                     document of January 15, 2015. In that document, EPA proposed the significant new use is any use in a consumer product, with a proposed exception for use of certain chemical substances in coatings, elastomers, adhesives, binders, and sealants that results in less than or equal to 0.1 percent by weight of TDI in a consumer product. In addition, EPA also proposed that the general SNUR exemption for persons who import or process these chemical substances as part of an article would not apply. EPA is hereby extending the comment period, which was set to end on March 16, 2015, to April 30, 2015.                

                    To submit comments, or access the docket, please follow the detailed instructions provided under                     **ADDRESSES**                     in the                     **Federal Register**                     document of January 15, 2015.
