Report recommends off-site disposal of secondary waste

its incineration has been problematic at best, and recommends that off-site disposal, decontamination, and destruction of the spent activated carbon should be pursued whenever possible.

Brine solutions are used to treat the gases arising from the incinerators. The solutions contain salt, water, suspended solids, and trace amount of heavy metals. The committee found that this type of waste is already disposed of off-site, and recommended that CMA continue to actively dispose of as much brine solution or salts off-site as possible.

Dunnage includes pallets and wood used to store the munitions. Generally, this waste is nonhazardous and can be easily disposed of through removal to an off-site facility. If exposed to a contaminant, the dunnage can be incinerated on-site. The report notes, however, that "there are no simple, direct, and reliable analytical techniques for determining contaminants that may be absorbed into the dunnage," and recommends that CMA improve techniques to enable more exact measurements of possible contamination to meet off-site shipping criteria and reduce the amount of waste dealt with on-site.

Scrap metal from the munitions casings and bulk containers is thermally treated to ensure destruction of any contaminants and stored temporarily on-site before shipment to an external disposal or recycling facility. The report recommends that scrap metal continue to be recycled or disposed of off-site as much as possible.

Plastics, in the form of the protective suits used in the facilities, can be disposed of on-site or off through treatment and then incineration. However, the report indicates that the capacity for on-site disposal is severely limited, and recommends CMA pursue off-site shipment, as long as it adheres to and enforces packing, shipping, monitoring, and treatment restrictions.
