Covered facilities must send Toxics Release Inventory (TRI) reports to the Environmental Protection Agency (EPA) and their designated state agency by the first of July each year for activities that took place during the preceding calendar year. These reports represent EPA’s TRI, a national compilation of toxic chemical release and waste management information, which is made available to the public.

Basic reporting requirements

For each toxic chemical known by the owner or operator to be manufactured (including imported), processed, or otherwise used in excess of an applicable threshold quantity in 372.25, .27, .28, or .29 at its covered facility for a calendar year, the owner or operator must submit to EPA and to the designated state agency in the state which the facility is located the following completed forms in accordance with the instructions in 40 CFR 372 Subpart E:

• EPA Form R (EPA Form 9350-1),
• EPA Form R Schedule 1 (EPA Form 9350-3) for the dioxin and dioxin-like compounds category, and
• EPA Form A (EPA Form 9350-2).

If the covered facility is located in Indian country, the facility shall submit (to the extent applicable) a completed EPA Form R, Form R Schedule 1, and Form A as described above to EPA and to the official designated by the tribal chairperson or equivalent elected official of the relevant Indian tribe, instead of to the state.

Each report under 40 CFR 372 for activities involving a toxic chemical that occurred during a calendar year at a covered facility must be submitted on or before the first of July of the next year. If the reporting deadline falls on a Saturday or Sunday, EPA will accept forms submitted on the following Monday (i.e., the next business day).
