PCAPP Monthly Recap – January 2020

Published: February 5, 2020 | Category: Monthly Recap, PCAPP News

PCAPP Stats January 31, 2020. Local project employment: 1,607. Local payroll paid to date: $1.91 billion. Quantity destroyed: 1,255.5 U.S. Tons.

Highlights

More than 70% of the 155mm projectiles in the PCD stockpile have been destroyed, representing the elimination of more than 46% of the total mustard agent in storage. A celebration of Pueblo’s defense of the nation is being planned for the spring to mark the looming 50% milestone.
The state of Colorado Department of Public Health and Environment approved the plant’s Multiple-Pathway Health Risk Assessment and is reviewing the pilot testing report in preparation for receiving the application for the final Resource Conservation and Recovery Act (RCRA) Part B operating permit.
Static Detonation Chamber (SDC) site preparations continued in January with Sprung structures rising to cover all three units. The SDCs will augment the main plant by destroying 4.2-inch mortar rounds and any other problematic projectiles not suitable for automated processing.
A third Immobilized Cell Bioreactor (ICB) module was seeded in preparation to help the main plant handle increased throughput of hydrolysate, the caustic wastewater resulting from chemical agent neutralization.
One of the main plant’s three 30-day hydrolysate storage tanks content is being drawn down and fed into the ICBs to allow manway gasket replacement needed to resolve a small weeping issue.
As of 30, 213,138 155mm projectiles have been processed in the main plant.
Baseline Reconfiguration of 4.2-inch boxed mortar rounds from boxed storage to pallets ready for processing continued. As of Jan. 30, 69,101 4.2-inch mortar rounds have been reconfigured.

The Pueblo Chemical Agent-Destruction Pilot Plant is a state-of-the-art facility built to destroy the chemical weapons stockpile stored at the U.S. Army Pueblo Chemical Depot, Colorado. The main plant uses neutralization followed by biotreatment to destroy the mustard agent stockpile. The safety of the workforce and neighboring communities is the project’s most important priority.
