Over the years, chemicals have been added and subtracted by EPA, which the agency can do at any time after public notice. More chemicals are added to the list than are subtracted. The first TRI report was published in 1987. EPA adds to the list on a regular basis, evaluating the risks and uses of each chemical. It is a tracking system.
Releases fall within federal and state environmental standards.
The TRI is designed to inform the public and emergency response personnel around these facilities about the nature and amount of chemicals at each site. If there were an emergency situation, officials would have specific information on hand to help them address any problems. There are federal and state environmental standards which govern the amount of each chemical which can be released. All the chemicals on the list fall below their daily limits on these environmental standards. No, the release levels are set within safe limits by the federal and state government.
