Pueblo Chemical Depot Explosive Destruction System (PCD EDS) Mission
• PCD EDS mission is to deploy two Phase 2 EDS units operating one
at a time to treat the following items:
• 1) Known stockpile items that have been previously over packed
(557 items)
• 2) Estimated numbers of leakers, rejects, and contaminated
bursters that will be identified during PCAPP operations (806
items)
• Operations will be campaigned starting with over packed items,
followed by 155mm projectiles, 105 mm projectiles, and 4.2”
mortars and contaminated bursters. A temporary closure of the
PCD EDS site is planned between each campaign.
• EDS Workload Summary
– 546 existing over packs
– 187 new leakers
– 539 rejects
– 11 DOT cylinders
– 80 explosive bursters

Operators place
the item in the
munition holder.
Linear-shaped charges are
attached along the munition body
and the item is placed in the
munition holder (up to 6 pack).
Operators slide the
munition holder into the
vessel.
Operators remotely detonate the
linear shaped charges to access
the munition body and destroy
explosives.
Once neutralization chemicals are
added, the vessel is heated with
steam and rotated to mix the contents.
A liquid sample is collected to verify
treatment goal ( less than 50 ppm) has
been met prior to draining.
The vessel is closed and
sealed.
Next water rinse is added, steam
heated, rotated, and drained. An air
sample is collected to verify treatment
goal has been met prior to opening
door and removing scrap metal.

Explosive Destruction System (EDS)
Pine Bluff Explosive Destruction System EDS inside of Environmental Enclosure
• The EDS operates inside of an environmental enclosure that
provides heat, air conditioning, and carbon filtered exhaust
air. Personnel entry and exit is accomplished through the
Personnel Decontamination Station (PDS)

EDS – Chemical Munitions Destruction Experience
• 2001 - 2012 Rocky Mountain Arsenal, CO; Camp Sibert, AL; Spring Valley, DC;
Dover Air Force Base, DE; Dugway Proving Ground, UT; Aberdeen Proving
Ground, MD
– Numerous munitions types containing agents GB, VX, HS, HD, HN3, CG,
and CK
• 2006-2010 Pine Bluff Arsenal, AR
– 1,227 chemical munitions destroyed including German Traktor Rockets,
4.2” mortars, 155, 105, and 75mm projectiles, 100 lb bombs, and
miscellaneous munitions containing CG, HS, HD, HN3, and several
arsenic based compounds
• Total number of munitions and other chemical agent items destroyed in an
EDS is 1,792

EDS – Advanced Fragment Suppression System
• In 2009, the Army fielded the Advanced Fragment Suppression System
(AFSS) which protects the interior of the EDS vessel and greatly reduces
the amount of solid waste generated from each operation. During
initial use to destroy 59 German Traktor Rockets, solid waste was
reduced by 12.5 tons

155mm 6-Pack EDS Testing
• In 2011, the Army developed hardware and successfully conducted
non-agent EDS testing using six 155mm projectiles
155mm projectiles after processing155mm projectiles ready to load

Universal Munition Storage Container (UMSC)
• Purpose: Create a storage container to over
pack leaking munitions that can then be
processed in the EDS without opening
̵ UMSC is made of High Density
Polyethylene (HDPE)
̵ Container designed for processing in EDS
̵ Increases operator safety treating leakers
̵ Reduces level of personnel protective
equipment
̵ Reduces processing time because it is not
opened
̵ Lightweight – reduces operator handling
hazards
̵ Inexpensive
• HDPE end cap is thermally heat welded to
HDPE tube using off the shelf technology
• Will allow for three- and six-pack munition
destruction configurations

from a single sheet of steel used
to hold three UMSCs at a time
2. Cradled munition is placed in modified
Commercial-Off-The-Shelf (COTS) plastic
fusion machine to insert cradle into UMSC
and thermally heat-weld end caps
1. Munition is secured in v-shaped
cradle with straps with flat end of
munition against spring steel
4. Indexing feature in end caps
line up with tabs in sheet metal
fixture
5. Fully assembled UMSC three-
pack configuration keeps
munitions contained and closest
to linear shape charges.
6. Two three-pack fixtures can be loaded
back-to-back to accomplish destruction of
six munitions at a time

Improvements Being Incorporated into EDS units for PCD EDS
• Tested EDS Improvements result in reducing
operational time from 36 hours to 10 hours:
• Improved valves
- Quarter turn ball valves
- Larger throat for faster draining and filling
• Larger pump and hose for quick transfer of liquids
• Steam heating for rapid heating of fill
- Current heating time is 1 to 2 hours; Steam
heating time is 20 minutes
• New three-piece clamp and closure system
- Automated closing system
- Faster opening and closing time
• Cold water injection cooling
- Current cooling time is 12 hours; New cooling
time is 30 minutes

Conclusion
.
The testing described in this briefing will allow the PCD EDS to
destroy the over packed munitions, rejects, and leakers
identified by the ACWA Program in a safe and efficient
manner that is protective of human health (workers and
residents), and the environment.
