Multiple chemical and biological simulant threat relevant releases are planned, with an estimated 40 releases during the course of two weeks. The simulants include: Bacillus subtilis var niger (B.g.), Erwinia herbicola (E.h.), Ovalbumin (OV), Methyl Salicylate (MeS), Triethyl Phosphate (TEP), Sulfur Hexafluoride (SF6), and C-4. There may be additional burned diesel fuel and other field contaminants incorporated into the releases as well. The number of actual releases conducted will be dependent on the weather conditions during the trials.
