Subsequently, the joint CAC/CDCAB added another recommendation to continue studying the use of the SDC for only those rocket motors that are not contaminated by chemical agent, based on the SDC “emerging as a new, on-site treatment option” (CDCAB, 2007).
More recent discussion in the public record focused on disposal of the rocket motors is limited. No recent public record is available regarding use of any nonhydrolysis technologies (i.e., any technologies other than those already in the BGCAPP design) other than an explosive destruction technology (EDT). An EDT Working Group6 examined the possible use of four types of EDT for disposing of three categories of items, including separated rocket motors that had not been contaminated with chemical agent. The four EDTs considered were these:
Since 2009, the CAC/CDCAB has issued two sets of positions or recommendations concerning use of an EDT at the BGCAPP, or at BGAD in support of BGCAPP operations. First, in December 2009, the CAC/CDCAB indicated that they would be willing to consider the use of an EDT to dispose of three categories of munitions, including separated rocket motors that had not been contaminated with chemical agent. They did place a number of caveats on this position, including
6This group was originally established in 2009. It was reestablished in 2011 at the request of the BGCAPP site project manager, who noted that “several factors are important to the destruction process selection, the current design has limitations of unknown capacity and the ACWA Program will work with the EDT Working Group to receive input on considerations for the final EDT decision” (CDCAB, 2011, p. 6). The site project manager’s presentation to the CAC/CDCAB of the EDTs in December 2011 as a “potential method to augment the basic destruction plans for BGCAPP” (CDCAB, 2011, p. 6) is available on the Web site. However, as of this writing, the related CAC/CDCAB discussion had not yet been posted.
