The Toxic Release Inventory, overseen by the US EPA, tracks the management of EPA-defined toxic chemicals that pose potential threats to human health and the environment. US facilities that meet the reporting criteria must provide information on how much of these chemicals are released into the environment through air, water or land disposal, or how much is managed through recycling, energy recovery and treatment.

This information is compiled by the EPA in order to inform decision-making by companies, government agencies, non-governmental organizations and the public.

Chemicals covered by the TRI program generally have one or more of the following endpoints:

  • Cancer or other chronic human health effects
  • Significant adverse acute human health effects
  • Significant adverse environmental effects

As of January 2021, the chemical list contains 770 individually listed chemicals and 33 chemical categories. A list of reportable chemicals can be found at https://www.epa.gov/toxics-release-inventory-tri-program/tri-listed-chemicals.

LPC manufacturers must demonstrate that their emissions and byproducts are not found on the TRI list.
