Each year, certain industrial facilities submit Toxics Release Inventory (TRI) data to EPA. The data are due by July 1 and cover waste management activities that occurred during the previous calendar year. A facility is required to report if it meets chemical activity thresholds AND:
- Is either in a covered industry sector and exceeds the employee threshold, OR
- Is specifically required to report based a determination by the Administrator under EPCRA 313(b)(2).
