Threshold determinations for reuse systems

If a facility employs a reuse system, how does it determine the amount that it must consider for threshold determinations?

For reuse systems, the amount considered for threshold determination purposes is the amount added to the system during the reporting year. If the system is completely empty and is started up during the year, a facility makes its threshold determination by adding the total amount needed to charge the system to any amount which is added to the system during the reporting year.  Additional guidance on threshold determinations can be found in the Toxic Release Inventory Reporting Forms and Instructions and the TRI Guidance Documents Web site.
