Toxic Release Inventory (TRI)
What is TRI? By Federal law, companies that use more than a certain minimum amount (the "threshold") of any of a long list of toxic chemicals are required to submit a Toxic Chemical Release Inventory (TRI) Form (also known as Form R). Every company in the country has the same filing deadline, July 1, covering the preceding calendar year. Forms are submitted directly to EPA, and to designated state agencies.
TRI reporting is a two-step process.
First, you need to determine whether you are required to submit a Form R. Your company is subject to reporting if it meets two criteria:
Then, for each listed chemical you use above threshold quantities, you will need to report on the Form R how much of the chemical you have "released", and where it went. In the TRI definition, "releases" include not only emitting listed chemicals into the environment, but also sending materials containing listed chemicals off-site for recycling or disposal. You are also asked to report on chemicals that you recycle internally. The purpose is to provide a picture of how you manage your waste.
Note that there are two quantities that matter for each chemical.
- The amount of each chemical that you "manufactured, processed, or otherwise used" determines whether you are required to file a report.
The amount of each chemical that you "released" is the amount that actually gets reported.

TRI Burden Reduction Rule (posted April 11, 2007).
This rule expands eligibility for TRI reporters to use Form A, a simpler form with less detailed information, in lieu of the more detailed Form R for PBT chemicals (except for dioxin and dioxin compounds), when there have been no releases or other disposal into the environment and the total amount of the chemical managed by treatment, energy recovery, and/or recycling is not more than 500 pounds.
