  • learn which chemicals facilities are managing and in what quantities.

While the preliminary data have not yet been through the complete TRI data quality process, the software facilities used to submit these data includes many automated quality checks that help prevent facilities from making common mistakes. EPA is now conducting additional quality checks on the preliminary data.
