Recent Changes to the SARA Title III TRI (Toxic Release Inventory)

Written By General

Think you are ready to file your Toxic Release Inventory (TRI), aka Form R, reports just the same as you did last year? Hold on a minute. While you might not have an issue doing this, make sure to check the TRI Chemical List for any changes before you press submit. The Environmental Protection Agency (EPA) is making major changes to the list over the next two years.

The EPA makes changes to the TRI chemical list on a periodic basis though EPA-initiated review and the chemical petitions process.

Recent TRI Chemical List ChangesUnder the automatic listing provisions of the 2020 National Defense Authorization Act: Four PFAS were added for reporting year 2022. Reporting forms on these chemicals are due July 1, 2023, for 2022 data if TRI reporting thresholds are met. Nine PFAS were added for reporting year 2023. Reporting forms on these chemicals are due July 1, 2024, for 2023 data if TRI reporting thresholds are met. See Addition of Certain PFAS to the TRI by the National Defense Authorization Act for more information. In November 2022, EPA added 12 chemicals in response to a petition submitted under Section 313(e) of EPCRA. Reporting forms on these chemicals are due July 1, 2024, for 2023 data if TRI reporting thresholds are met.

For the Cliff’s Notes version from our technical expert (and skip the clicking)…Or easier still…just call us to help!

For the 2022 reporting year, due by July 1, 2023, the EPA has added four Per- and Polyfluorinated Substances (PFAS) to the EPCRA Section 313 reportable chemical list:

CAS RN                Chemical name

375-73-5             Perfluorobutane sulfonic acid (de minimis 0.1%)

29420-49-3         Potassium perfluorobutane sulfonate

65104-45-2         2-Propenoic acid, 2-methyl-, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-heneicosafluorododecyl ester, polymer with 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10- heptadecafluorodecyl 2-methyl-2-propenoate, methyl 2-methyl-2-propenoate, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,14- pentacosafluorotetradecyl 2-methyl-2-propenoate and 3,3,4,4,5,5,6,6,7,7,8,8,8- tridecafluorooctyl 2-methyl-2-propenoate

203743-03-7 2-  Propenoic acid, 2-methyl-, hexadecyl ester, polymers with 2-hydroxyethyl methacrylate, γ-ω-perfluoro-C10-16-alkyl acrylate and stearyl methacrylate

Note that the de minimis value for each of these PFAS is 1% unless otherwise noted above. The manufacturing, processing, and otherwise use reporting threshold is 100 pounds for each of the PFAS listed above.

Please also note that the PFAS chemical names and CasRNs are listed on separate tables from the remainder of reportable chemicals on the List of Lists.

For the 2023 reporting year, due by July 1, 2024, the EPA automatically added in 9 PFAS to the EPCRA Section 313 reportable chemical list:

  • 375-22-4. Perfluorobutanoic acid

  • 2218-54-4 Sodium perfluorobutanoate

  • 2966-54-3 Potassium heptafluorobutanoate

  • 10495-86-0 Ammonium perfluorobutanoate

  • 45048-62-2. Perfluorobutanoate

  • 2728655-42-1 Alcohols, C8-16, γ-ω-perfluoro, reaction products with 1,6-diisocyanatohexane, glycidol and stearyl alc.

  • 2738952-61-7 Acetamide, N-[3-(dimethylamino)propyl]-, 2-[(γ-ω-perfluoro-C4-20-alkyl)thio] derivs.

  • 2742694-36-4 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

  • 2744262-09-5 Acetic acid, 2-[(γ-ω-perfluoro-C4-20-alkyl)thio] derivs., 2-hydroxypropyl esters

The EPA has also added the following 12 chemicals to the EPCRA Section 313 list beginning reporting year 2023, in response to a petition filed by the Toxics Use Reduction Institute:

  • 683-18-1dibutyltin dichloride

  • 96-23-11,3-dichloro-2-propanol75-12-7formamide

  • 1222-05-51,3,4,6,7,8-Hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[g]-2-benzopyran;*111-41-1n-hydroxyethylethylenediamine

  • 5064-31-3nitrilotriacetic acid trisodium salt140-66-9p-(1,1,3,3-Tetramethylbutyl) phenol87-61-61,2,3-trichlorobenzene

  • 2451-62-9triglycidyl isocyanurate115-96-8tris(2-chloroethyl) phosphate13674-87-8tris(1,3-dichloro-2-propyl) phosphate

  • 25155-23-1tris(dimethylphenol) phosphate

*classified as a Persistent Bioaccumulative, and Toxic (PBT) chemical with a 100 pound reporting threshold
