During full-scale operations, the soil moisture content ranged from 10.0 to 25.5% and averaged 17.6%.
The following table lists the operating limits for the incineration system that were approved by
the USEPA and TNRCC prior to full-scale operation of the system. These operating limits were
developed based on the results of the trial burns and risk burns.
