Final Rule: Addition of 12 Chemicals to the Toxics Release Inventory
On this page:
Rule Summary
In November 2022, EPA finalized a rule adding 12 chemicals to the list of toxic chemicals subject to Toxics Release Inventory (TRI) reporting requirements. Available data show these chemicals have moderately high to high human health toxicity and/or are highly toxic to aquatic organisms. EPA has classified one of the chemicals as a persistent, bioaccumulative, and toxic (PBT) chemical and designated it as a chemical of special concern with a 100-pound reporting threshold: 1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[g]-2-benzopyran, or HHCB. This rule provides communities with important information about how these chemicals are being managed in their communities.
The chemicals now subject to TRI reporting requirements are:
• Dibutyltin dichloride; 683-18-1
• 1,3-Dichloro-2-propanol; 96-23-1
• Formamide; 75-12-7
• 1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[g]-2-benzopyran; 1222-05-5
• N-Hydroxyethylethylenediamine; 111-41-1
• Nitrilotriacetic acid trisodium salt; 5064-31-3
• p-(1,1,3,3-Tetramethylbutyl)phenol; 140-66-9
• 1,2,3-Trichlorobenzene; 87-61-6
• Triglycidyl isocyanurate; 2451-62-9
• Tris(2-chloroethyl) phosphate; 115-96-8
• Tris(1,3-dichloro-2-propyl) phosphate; 13674-87-8
• Tris(dimethylphenol) phosphate; 25155-23-1
Rule History
On May 6, 2014, EPA received a petition from the Toxics Use Reduction Institute (TURI) requesting that EPA add 25 chemicals to the TRI list of chemicals under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA).
In response to the petition, EPA added 12 of the 25 chemicals to the TRI chemical list. In separate, unrelated actions, three of the 25 chemicals (1-bromopropane, nonylphenol, and 1,2,5,6,9,10-hexabromocyclododecane) were previously added to the TRI chemical list. Of the remaining 10 chemicals, EPA determined that the available data for nine chemicals were not sufficient for EPA to find that the chemicals meet the EPCRA §313 listing criteria for human health or ecological effects. Regarding the final chemical, EPA did not add octabromodiphenyl ether, as EPA's production volume screen indicated that no TRI reporting forms would be filed for this chemical.
