CLOSURE WASTES FROM BASELINE INCINERATION FACILITIES

The closure wastes at JACADS included significant amounts of legacy wastes that were generated during operations and stored awaiting disposal at the end of the munitions disposal campaigns. At the five currently operating disposal sites, much of this waste is being managed and disposed of during the operations phase and therefore will not be part of the closure. Other than the wastes from operations, the material generated during closure of the four baseline sites will be similar in type and quantity to those generated at JACADS with two notable exceptions, which are discussed below.

Definitive estimates of the quantities and methods for disposal of closure wastes had not been finalized by the Army when this report was being prepared. However, rough projections of waste that will be generated during closure were available. These are summarized in Tables 4-1 and 4-2. The ultimate end use of each site

cFinal end state for bulk solid wastes at the Anniston Chemical Agent Disposal Facility (ANCDF) and NECDF is yet to be determined, so these two sites are not included in estimate.
