What’s New for Toxic Release Inventory reporting? 

Each year, industrial facilities must submit their Toxic Release Inventory (TRI) data to the United States Environmental Protection Agency (USEPA). The deadline for Reporting Year (RY) 2023 is July 1, 2024. There have been some changes to company and chemical reporting requirements for RY2023 of which anyone who prepares TRI reporting forms should be aware. The changes, as described on the USEPA’s Reporting for TRI Facilities webpage (Reporting for TRI Facilities), are provided below. 

Miscellaneous Changes1 

  • “TRI facilities must report their foreign parent company, if applicable, in the following data elements: 
    • Part I, Section 5.3: Foreign parent company
    • Part I, Section 5.4: Dun & Bradstreet (D&B) number of foreign parent company
  • The de minimis levels for four chemicals have been changed from 1.0% to 0.1% since these chemicals have been classified as carcinogens by the International Agency for Research on Cancer:
    • I. Direct Blue 218 (CAS 28407-37-6)
    • 1,1,1-Trichloroethane (CAS 71-55-6)
    • Diphenylamine (CAS 122-39-4)
    • N-Methylolacrylamide (CAS 924-42-5)”

Chemical List Changes 

  • Facilities must report on nine new per- and polyfluoroalkyl substances (PFAS) and 2,3
    • The new PFAS for RY2023 includes:
      • Acetamide, N-[3-(dimethylamino)propyl]-, 2-[(γ-ω-perfluoro-C4-20-alkyl)thio] derivs. (CAS 2738952-61-7)
      • Acetic acid, 2-[(γ-ω-perfluoro-C4-20-alkyl)thio] derivs., 2-hydroxypropyl esters (CAS 2744262-09-5)
      • Acetamide, N-(2-aminoethyl)-, 2-[(γ-ω-perfluoro-C4-20-alkyl)thio] derivs., polymers with N1,N1-dimethyl-1,3-propanediamine, epichlorohydrin and ethylenediamine, oxidized (CAS 2742694-36-4)
      • Alcohols, C8-16, γ-ω-perfluoro, reaction products with 1,6-diisocyanatohexane, glycidol and stearyl alc. (CAS 2728655-42-1)
      • Ammonium perfluorobutanoate (CAS 10495860)
      • Perfluorobutanoate (CAS 45048-62-2)
      • Perfluorobutanoic acid (CAS 375-22-4)
      • Potassium heptafluorobutanoate (CAS 2966543)
      • Sodium perfluorobutanoate (CAS 2218-54-4)
    • The 12 new chemicals for RY2023 include:
      • Dibutyltin dichloride (CAS 683-18-1)
      • 1,3-Dichloro-2-propanol (CAS 96-23-1)
      • Formamide (CAS 75-12-7)
      • 1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[g]-2-benzopyran (CAS 1222-05-5) 
      • N-Hydr xyethylethylenediamine (CAS 111-41-1)
      • Nitrilotriacetic acid trisodium salt (CAS 5064313)
      • p-(1,1,3,3-Tetramethylbutyl)phenol (CAS 140669)
      • 1,2,3-Trichlorobenzene (CAS 87-61-6)
      • Triglycidyl isocyanurate (CAS 2451-62-9)
      • Tris(2-chloroethyl) phosphate (CAS 115-96-8)
      • Tris(1,3-dichloro-2-propyl) phosphate (CAS 13674-87-8)
      • Tris(dimethylphenol) phosphate (CAS 25155231)

Anticipated Changes for RY2024 

Looking ahead, reporting on seven additional PFAS chemicals will be required in RY20242 (196 total PFAS are reportable), and the de minimis levels for RY2024 will be changing from 1.0 percent to 0.1 percent for the following chemicals: 

  • Some cobalt compounds (N096): soluble cobalt (II) salts, cobalt (II) oxide
  • Some antimony (7440-36-0) and antimony compounds (N010): trivalent antimony

Additionally, for RY2024, all PFAS will be designated as “chemicals of special concern,” and the de minimis exemption, Form A Certification, and range reporting will be no longer available for PFAS TRI reporting.2 PFAS have been used to formulate some firefighting foams (e.g., aqueous film forming foam [AFFF]) that have been stored and used at facilities for fire suppression, fire training, and flammable vapor suppression. Use of a fire suppression system for system testing, for training, or to suppress a fire as part of an emergency response would constitute otherwise use of the TRI-listed chemicals in the firefighting foam.
