Appendix B ANCDF Campaign Schedule Options Table B-1 (p. 50) shows the order and duration (in days) for each planned disposal campaign at the Anniston Chemical Agent Disposal Facility (ANCDF) for all of the munitions stored at Anniston Army Depot according to four schedules. This table was developed by Science Applications International Corporation (SAIC), an Army contractor. The first schedule is the original plan proposed for ANCDF before the presence of gelled GB rockets at Anniston was discovered. The second schedule retains the original order of disposal campaigns and changeovers but assumes a processing ~ A, A, ~ rate of 9.2 gelled GB M55 rockets per hour. Schedules three and four are variations of the 49 ANCDF modified plan. These schedules provide for coprocessing or complementary processing of other munitions while gelled GB M55 rockets are processed. The modified plan also has fewer changeover periods since all the GB is processed before munitions or con- tainers of VX nerve agent or mustard agent are pro- cessed. The first schedule under the modified plan pro- vides for a processing rate of 9.2 gelled GB rockets per hour, whereas the second schedule indicates the num- ber of days necessary for each campaign if processing of the gelled GB rockets at Anniston is restricted to the permitted rate of 1.6 rockets per hour that was used at TOCDF.
