Toxics Release Inventory (TRI) Chemicals Reporting Change

At Wenck, we make it our duty to stay current on the latest technical details, regulations, and movements across all our market areas. As your partner and advocate, we are behind the scenes, managing the risk for you with economic efficiency in mind.

With a passion for air, water, waste, land/natural resources, and infrastructure, we utilize our discrete expertise to ensure your organization is operational and thriving. For this reason, Wenck would like to notify you of the following active regulatory changes that could affect your facility if you are subject to the Environmental Protection Agency (EPA) Toxic Release Inventory (TRI) reporting (commonly referred to as “SARA 313”) for Reporting Year 2017: 

1) New TRI Chemical Category: Hexabromocyclododecane (HBCD) Category Added 
2) 2017 TRI North American Industry Classification System (NAICS) Codes Adopted
3) 1-Bromopropane Added to the TRI List of Reportable Chemicals
4) De Minimis Levels for Several Chemicals Updated

The de minimis levels for several chemicals have been changed from 1.0% to 0.1% since these chemicals are now classified as OSHA carcinogens due to assessments by the International Agency for Research on Cancer and the National Toxicology Program Report on Carcinogens ( These chemicals, along with their Chemical Abstract Numbers (CAS), include:

• Cumene (98-82-8)
• Diazinon (333-41-5)
• 1,2-Dichloropropane (78-87-5)
• Malathion (121-75-5)
• Methyl Isobutyl Ketone (108-10-1)
• Parathion (56-38-2)
• Sodium Pentachlorophenate (131-52-2)
• 1,1,1,2-Tetrachloroethane (630-20-6)
• 1,1,2,2-Tetrachloroethane (79-34-5)

Reporting criteria factors in industry (manufacturing, mining, power and utilities) and are based on a facility’s NAICS code, the number of full-time employees (10 or more), as well as manufacturing, processing, and/or otherwise using quantities above threshold levels of specific TRI-listed chemicals per year. Federal facilities are required to report if they meet the employee and chemical use thresholds regardless of their NAICS code.
