On November 28, 2016, the USEPA published a final rule that adds a HBCD category to the TRI list of reportable chemicals. The HBCD category includes two CASRNs:

  • 3194-55-6 (1,2,5,6,9,10-HBCD) and
  • 25637-99-4 (HBCD).

Since the HBCD category meets the TRI criteria for a persistent bioaccumulative toxic (PBT) chemical, USEPA established a reporting threshold of 100 lbs for the category.

The rule was effective November 30, 2016, and applies to the 2017 reporting year with the first reports due by July 1, 2018.

Toxic Release Inventory reports for calendar year 2016 are due by July 1, 2017
