On March 15, 2017, the U.S. Environmental Protection Agency (EPA) announced it would be extending the comment period on the Toxic Substances Control Act (TSCA) Inventory Notification (Active-Inactive) proposed rule issued on January 13, 2017.  On March 16, 2017, however, EPA rescinded this extension, stating it was issued in error, but did state that it would “make every effort to consider comments received outside of the formal comment period, if provided by March 24, 2017.”  EPA is accepting comments in Docket ID EPA-HQ-OPPT-2016-0426 on the www.regulations.gov website.  More information on this proposed rule is available in memorandum EPA Proposes Requirements for TSCA Inventory Notification (Active-Inactive).
