The Army, having committed to the safe and complete disposal of the Anniston Army Depot stockpile, shall only process and destroy at its Anniston Demilitarization Facility the stocks stored there as of the date of its contract with a commercial company to do so. No other materials, except those materials used to demonstrate the performance of incinerators and pollution abatement systems during a trial burn demonstration, and the resulting wastes generated by the Anniston facility, may be processed in the Anniston facility during its lifetime.
