Under this section, The EPA is required to establish the Toxics Release Inventory (TRI), an inventory of routine toxic chemical emissions from certain facilities. This inventory is intended to inform the public about releases of toxic chemicals. The data gathered is also intended to assist in research and development of regulations, guidelines, and standards. The original data requirements for the TRI, specified in SARA Title III, have been greatly expanded by the Pollution Prevention Act of 1990. The TRI must now also include information on source reduction, recycling and treatment.
