Non-Stockpile Inventory

The non-stockpile inventory includes numerous containers of chemical agents of various types and sizes that have accumulated over the years. In general, these are stored at stockpile sites. There are many treatment options available for these bulk containers the most obvious is to use the stockpile chemical disposal facilities (CDFs), although modifications may be required and permit modifications may be difficult to obtain. 

The entire non-stockpile inventory of binary CWM components is stored in canisters and drnms at Pine Bluff Arsenal, a stockpile site. Options for treatment include destruction in the Pine Bluff Chemical Disposal Facility, direct destruction in a plasma arc system, or chemical neutralization followed by oxidative posttreatment of the neutralents. The high concentration of fluorine in the binary component DF raises concerns about corrosion in some treatment systems. 

This chapter described the non-stockpile inventory, which comprises a greater variety of chemical agents than the stockpile inventory. It includes blister, nerve, blood, and choking agents, as well as militarized industrial chemicals and binary agents, and its condition is highly variable—some items, for instance, have severely deteriorated during decades of burial. 

Finding 2-la. PBA has the largest known non-stockpile inventory. It contains almost 70,000 items, inclnding explosive and nonexplosive monitions with diverse chemical fills, binary agent precnrsors, CAIS, chemical samples, and empty ton containers. If the CWC treaty deadline is not extended, these items mnst be destroyed by April 29, 2007. 

Pine Bluff. The incineration facility at Pine Bluff provides a technically feasible alternative for destruction of less than 10 percent of the 69,878 non-stockpile items stored there because its design does not include facilities for opening bulk containers of agent and CWM binary components (Appendix C). However, inclusion of such capability in the non-stockpile PBNSF would enable transfer of these liquid chemicals to vessels suitable as feed tanks for the PBCDF liquid incinerator. This modification, plus the addition of DF and QL monitoring systems at the Pine Bluff Chemical Disposal Facility (PBCDF), would allow incineration of the great majority of the PBA non-stockpile inventory. 

Finding 2-3. The stockpile chemical disposal facilities (CDFs) are technically capable of safely disposing of a portion of the non-stockpile inventory, including secondary wastes, but could face challenging regulatory and public acceptability hurdles, especially if they accepted NSCWM from other sites or out of state. Although any NSCWM or secondary waste might be a candidate, materiel already located at stockpile sites—or, secondarily, located within the same state—may present less of an acceptance problem than NSCWM from other states.

There are also 69,878 non-stockpile items stored at Pine Bluff, by far the largest part of the non-stockpile inventory. For discussion and categorization purposes, the known inventory of non-stockpile materiel found at Pine Bluff is grouped below into six categories and listed in order of decreasing compatibility with the Pine Bluff CDF.

The NRC will establish a committee to review and evaluate international technologies for the destruction of non-stockpile chemical materiel. The committee will provide independent scientific and technical evaluations of international systems, facilities, and disposal technologies currently employed or under research and development in countries with inventories of non-stockpile materiel for their treatment and destruction. The committee will compare these technologies with those utilized by the U.S. Army Project Manager for Non-Stockpile Chemical Materiel, in an overall effort to determine and further define state-of-the-art technologies for destruction worldwide of non-stockpile chemical materiel. The committee will ... 

Review and evaluate systems and technologies employed or under development in countries with inventories of non-stockpile materiel for the treatment and destruction of non-stockpile munitions, materiel, and secondary waste streams. Such countries include, but are not limited to, France, Germany, lapan, Russia, and the United Kingdom. 

Appendix A shows the inventory of recovered nonstockpile items that have been stored at various locations awaiting treatment and disposal, which is scheduled to be completed prior to the 2007 CWC treaty deadline using currently available NSCMP equipment. Except for the listed binary agent precursors (which postdate the period when the Army practiced burial of non-stockpile chemical warfare materiel), the tables in Appendix A exemplify the great variety of items that could be encountered during future recovery operations. 

Tables A-l through A-4, reprinted from an earlier report (NRC, 2005), show inventories of non-stockpile items that have been stored at various military sites for eventual treatment and disposal. The tables are reproduced here to illustrate the variety of non-stockpile items that exist and that could be encountered during future recovery operations at non-stockpile burial sites.
