New Reporting Tools, Chemicals and Deadlines

TRI or SARA 313 reporting provides the general public with detailed information on nearly 650 chemicals, including their disposal or other releases by local facilities. U.S. EPA has created new assistance tools and training materials for facilities to determine if they meet the threshold requirement for reporting TRI data under Section 313 of EPCRA.

  • Online Threshold Screening Tool:
    • This new threshold screening tool is being made available solely as a reference tool to help determine whether your facility is legally obligated to report TRI data to U.S. EPA. The Tool provides an interactive environment that will guide a facility through the calculations for industry sector, employee and chemical thresholds.
  • Reporting Training Materials:
    • Basic and advanced TRI training slides and modules are now available to assist facilities who must submit TRI reports for reporting year 2010.

If your facility does meet a threshold for reporting TRI data to U.S. EPA, reporting forms for reporting year 2010 are now available on the U.S. EPA TRI website. Reports are to be submitted by July 1st, 2011.

Also, 16 new chemicals have been added to the list of TRI chemicals; however, companies will not have to report on them until July 2012.

  • Chemical Names:
    • 1-Amino-2,4-dibromoanthraquinone
    • Phenolphthalein
    • 2,2-bis(Bromomethyl)-1,3-propanediol
    • Tetrafluoroethylene
