Parsons Wins $164M USACE Contract for Design and Construction of Explosives Decomposition Chamber

Parsons Corporation announced today that the company was selected by the United States Army Corps of Engineers (USACE) Norfolk District to deliver a new Explosive Decomposition Chamber (EDC) facility at Holston Army Ammunition Plant (HSAAP) in Kingsport, Tennessee. The four-year, $164 million contract is new work for the firm.

“Our team is uniquely equipped to deliver solutions for the most complex environmental challenges that our clients face,” said Jon Moretta, president, Engineered Systems, for Parsons. “This new facility will meet the Army’s mission of reducing environmental impacts by transitioning from the open burning explosive waste treatment process to a technology-driven closed destruction solution. We look forward to leveraging our technical design, engineering, and complex delivery capabilities in support of this mission as part of our continued commitment to innovative solutions and environmental stewardship.”

HSAAP, a government-owned, contractor-operated (GOCO) facility, is a major supplier of explosive materials to the Department of Defense and, consequently, generates explosives waste which has historically been open burned since the 1940s. Under this contract, Parsons will provide technical design and engineering, permitting, and delivery of the EDC facility. This emission-controlled thermal treatment facility will process the hazardous explosive waste streams, significantly reducing the need for open burning, and will satisfy the federal government’s requirements to treat bulk explosive waste safely and effectively.

This project expands Parsons’ role in supporting Army efforts to minimize the environmental impact of Army Ammunition Plants. In September 2021, Parsons was awarded a contract for a new Energetic Waste Incinerator and Contaminated Waste Processor project at Radford Army Ammunition Plant in Virginia. Like the new EDC facility project, the work at Radford will provide a facility to treat hazardous energetic waste streams in an environmentally friendly manner. Recent world events, such as the conflict in Ukraine, have spurred an increase in munitions production at GOCO army ammunition plants, underscoring the importance of the Army’s transition to more sustainable solutions to mitigate adverse environmental impacts.
