Appendix C Analysis of the Pine Bluff Non-Stockpile Facility Schedule ANALYSIS OF SCHEDULE LEADING TO START-UP AND FOR PROCESSING MUNITIONS Table C-1 shows the major milestones for the design, con- struction, and operation of the Pine Bluff Non-Stockpile Fa- cility (PBNSF); Figure C-1 illustrates the schedule for their completion. The processing schedule is based on the following inven- tory. As information from inspections and other records is reexamined, the numbers may change slightly but not sig- nificantly. The inventory consists of the following: 730 4.2-in. mortar rounds 32 (other) mortar rounds 470 German Traktor rockets (GTR), 38 with warhead only, 31 that are full assemblies that is, they include the rocket motor and propellant 9 bombs 17 projectiles The operating plan for PBNSF is based on the following: . All chemical weapon items are to be processed in the explosive containment chamber (ECC)- 1 or ECC-2; all GTRs would be processed in the ECC-2 (U.S. Army, 2003a). However: Mortars, bombs, and projectiles that are too sensi- tive for further standard handling will be processed through the EDS- 1 or EDS-2 (U.S. Army, 2003b). The plan is still evolving for processing GTRs con- taining both a motor and a burster classed as sensi- tive. GTRs with motors contain too large a load of energetics to process even in the EDS-2.

Items with energetics but no agent fill will instead be processed through the detonation chamber (U.S. Army, 2003a). Items with no energetics but with agent fill (and those with no energetics and no fill) will instead be pro- cessed through the projectile washout system (U.S. Army, 2003a). The design basis capacity is 10 rounds per shift (5 rounds per shift per ECC) (U.S. Army, 2003a). The operations plan is for one 10-hour shift per day, 5 days per week. Operation at 6 days per week would be a particularly expensive and cumbersome option. The wide range of staff support functions provided through

After every 10 days, 1 day of maintenance is required. This also fits well with the EDS operation of two days per shot, two shots per week and 80 percent availabil- ity expected for the equipment. Two of seven GTRs that were examined contained ma- terial not covered under the Chemical Weapons Conven- tion. However, extrapolating this observation to project that a significant number of GTRs can be processed after the treaty deadline would be presumptuous. . THE BASE CASE: USE OF THE PINE BLUFF NON- STOCKPILE FACILITY FOR ALL ITEMS The processing schedule based on the above information calls for completion 88 days ahead of the scheduled comple- tion date of March 31, 2007, as shown in Tables C-2 and C-3 and Figure C-2. However, if only the ECC-2 can be used to process GTRs and if mortars, bombs, and projectiles con- taining a different agent cannot be simultaneously processed in the ECC-1 because of limitations such as the single-agent detection capabilities of the air monitoring analyzers, the overall design capacity of PBNSF drops to five GTRs per shift during the processing of GTRs. This may cause serious capacity problems and reduce to only 6 days the flexibility built into the schedule to meet an on-time completion of PBNSF operations (see Table C-4 and Figure Cub. OPTION 1: USE OF THE EDS-2 AT HIGH CAPACITY BUT WITHOUT APPROVAL FOR THREE ROUNDS PER SHOT IN THE EDS-1 Option 1 uses two EDS-12 units and one EDS-2 unit to process mortars, bombs, and projectiles, and the EDS-2 unit also is used for the GTRs (see Tables C-5 and C-6 and Fig- ure C-4). The Army is confident that high-capacity opera- tion of the EDS-2 processing six mortars, bombs, or projec- 2One of the 2 EDS-1 units is that which is associated with the PBMAS operations and would be used to process both stable and sensitive rounds.

APPENDIX C tiles per shot in the EDS-2 or three or more GTRs per shot is feasible, but this is still to be demonstrated and approved by regulatory authorities. Likewise, EDS ability to break the GTR agent cavity and the neutralization chemistry to be used for processing the GTR agent fills must be demonstrated and approved by regulatory authorities. A capacity greater than one item per shot ("low capacity" in Table C-6) for the EDS- 1 is not needed. In addition to the processing benefits cov- ered in Chapter 6 of this report, this approach avoids entirely the need for the currently designed PBNSF while providing for completion of non-stockpile disposal operations 76 days prior to the scheduled completion date of March 31, 2007. In summary, an all-EDS approach requires the following: Demonstration and permitting of decoupling of GTR motors from warheads. Demonstration and permitting of EDS-2 capability to break GTR agent cavity and of neutralization chemistry technology for GTRs by the date shown in Table C-6. Demonstration and permitting of six rounds per shot in the EDS-2 for mortars, bombs, and projectiles and dem- onstration and permitting of at least three rounds per shot in the EDS-2 for GTRs. 81 Demonstration and permitting of multiple-round shots in the EDS- 1 (not required, but helpful). Purchase and start-up of a second EDS-2 (not required, and probably too expensive). OPTION 2: USE OF MULTIPLE EDS UNITS ALONG WITH USE OF THE PINE BLUFF NON-STOCKPILE FACILITY ECC-2 TO PROCESS GERMAN TRAKTOR ROCKETS Option 2 uses two EDS-1 units and one EDS-2 unit to process mortars, bombs, and projectiles along with the ECC- 2 for processing all of the GTRs. Although the Army is con- fident that more than three mortars will fit into the EDS-2 for each shot, such extra capacity is not essential that is, low- capacity, single-shot operation was anticipated in develop- ing Tables C-7 and C-8 and Figure C-5. The limiting opera- tion is the processing of GTRs in the ECC-2. In addition to the processing benefits covered in Chapter 6 this report, this mixed approach for PBNSF using an ECC-2 and multiple EDS units increases schedule flexibility by allowing for completion 139 days prior to the scheduled completion date of March 31, 2007.
