A well-designed process for disposal of the separated rocket motors will provide physical safety for the workers controlling or performing the work activities, protect the community and local environment, minimize risks to the physical infrastructure and capital equipment required to perform the work, and produce a manageable waste stream that is minimized to the greatest extent possible.

The chemical reactions in the propellant generate heat on an ongoing basis, and the storage box in which the separated rocket motors will be placed will influence heat transfer to and from a given rocket motor and the others boxed with it and heat exchange between ambient air and the propellant. The design of the box, including its ability to dissipate heat generated in the propellant grains and its ability to maintain a dry storage environment, will determine the validity of the previous safety studies vis-à-vis the new configuration of the cut rocket motors.

Recommendation 2-2. Blue Grass Chemical Agent-Destruction Pilot Plant program staff should ensure that the storage and shipping containers minimize the exposure of rocket motors to environmental conditions that will accelerate propellant degradation, such as heat and humidity, and allow adequate heat dissipation from the separated rocket motors.

of the lead may remain in the motor carcass after firing. Any technology used to dispose of the separated rocket motors would need to ensure minimal redistribution of lead through the environment and protection of employees and the public.
