Environmental Protection Agency (EPA).


Proposed rule; extension of comment period.


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.


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.


Follow the detailed instructions provided under ADDRESSES in the Federal Register document of January 15, 2015 (80 FR 2068) (FRL-9915-62).
