IDEM > Reporting > TRI: Toxic Release Inventory > TRI: Who Must Report? TRI: Who Must Report?

There are basically four criteria that must be met to require a facility to report to TRI:

  1. Facilities must be a manufacturing facility (primary SIC code in 20 -39); or federal facility; or one of the following sectors (effective since 1998):
    • Coal Mining (SIC = 1221, 1222, 1231)
    • Electricity Generating Facilities (limited to those that burn coal and/or oil for the purpose of generating electricity for distribution into commerce (SIC = 4911, 4931, 4939)
    • Treatment, Storage and Disposal Facilities (Subtitle C) (SIC = 4953)
    • Chemical and Allied Products - Wholesale (SIC = 5169)
    • Petroleum Bulk Terminals and Plants (SIC = 5171)
    • Solvent Recovery Facilities (SIC = 7389)
    • Metal Mines (none in Indiana)
  2. Facilities must have the equivalent of 10 full-time employees;
  3. The chemical must be on the TRI list of 650 specific toxic chemicals or chemical categories;
  4. Facilities must either manufacture or process more than 25,000 lbs of the chemical or otherwise use more than 10,000 lbs during the year.

Therefore, not all manufacturer's pollution is reported on TRI. However, TRI does have certain advantages:

  1. It is multi-media. Facilities must report the amounts they release to air, land, water, and underground injection, and must report how much they send off-site;
  2. All quantities are reported in pounds. This reporting has an advantage compared to other databases, which often report releases as concentrations, or other databases which report releases by volume of waste. These measures are often impossible to convert into pounds;
  3. This information is Federally mandated to be publicly available, by electronic and other means, to everyone. This means that it's relatively easy to obtain TRI data and that the data is well-known,and becoming a "yardstick" for measuring progress in pollution prevention and waste generation.

The TRI data is reported by individual facilities, who send their reports to Federal EPA and IDEM every year. These reports are currently filled out on a five page "Form R" and submitted either in hard copy or computer disk. EPA and IDEM take these forms and convert them into electronic databases. To better understand Indiana TRI data, it is recommended that you contact IDEM's Office of Pollution Prevention and Technical Assistance at (800) 998-7901.
