The Program Executive Office, Assembled Chemical Weapons Alternatives (PEO ACWA) announced the restarting of operations at the Pueblo Chemical Agent-Destruction Pilot Plant Explosive Destruction System (PCAPP EDS), they announced on Oct. 6.

Repairs on the system were necessary after the dismantling of four 155mm projectiles. In August, it was discovered that the EDS sealing surface had been damaged in the dismantling process, requiring repairs.

“During the Aug. 6 operation, a compression divot was created,” Site Project Manager Bruce Huenefeld said. “In order to repair the divot, the entire seal surface had to be machined out and built back up with two layers of welding.”

According to the report the machining and repair process was able to bring the system back to its operational specifications and the system passed leak tests allowing the Colorado Department of Public Health and Environment to approve restarting its operations.

“It was good that we proceeded carefully on the repair and verified and documented each step,” Huenefeld said. “The end result is a fully restored EDS door sealing surface that is as good as or better than before the damage.”

The Pueblo site is tasked with eliminating a portion of U.S. stockpiled chemical weapons, to date it has eliminated 351 units with 209 munitions left to be dismantled.
