The U.S Army has awarded five companies including Tetra Tech Inc a contract worth $489 million to provide program management and technical support for chemical weapons demilitarization programs at facilities across the United States. Under the indefinite delivery/indefinite quantity contract with the Army’s Chemical Materials Agency program, Tetra Tech will support the CMA and the Assembled Chemical Weapons Alternatives program for the next five years. Tetra Tech also will assist CMA in managing its non-stockpile chemical material program and chemical stockpile emergency preparedness program. The company will also provide a variety of program management, integration, and technical services to help support efficient destruction of chemical warfare and related material. This support includes environmental studies, design, monitoring, operations and maintenance, quality assurance, safety, and logistics support services. “The Integration Support V, or PAIS V, contract activities will help the U.S. Army to comply with international chemical weapons conventions and move towards ultimate closure of chemical agent disposal facilities and stockpile storage areas”, Tetra Tech said.
