The Blue Grass Chemical Agent-Destruction Pilot Plant (BGCAPP) is a chemical weapons destruction facility under construction. The plant is being built to destroy the chemical weapons stockpile at the Blue Grass Army Depot (BGAD), near Richmond, Kentucky. The plant is dedicated to the destruction of 523 tons of nerve agents sarin (GB) and VX, and mustard agent, which constitute about two percent of the United States chemical weapons stockpile.[1]

A systems contract was awarded in June 2003 to a joint venture team composed of the California companies Bechtel National, Inc., and Parsons Infrastructure and Technology Group, Inc. The Bechtel Parsons Blue Grass team is contracted to develop a design-build plan and then design, construct, systemize, pilot test, operate and close the Blue Grass Chemical Agent-Destruction Pilot Plant.
In March 2005 the design-build-operate-close schedule was extended to make the program more affordable on an annual basis. Site preparation work and the construction of support buildings continued and final designs for the remaining BGCAPP facilities were completed in 2010. After systemization of the facility, destruction operations are expected to begin in 2020 and to be complete by 2023.[2] The plant will operate until all the chemical weapons have been destroyed. Closure activities (shut-down, dismantling, and restoration of site) are slated to be wrapped up by 2026. This schedule exceeds the terms of the Chemical Weapons Convention.
Legislation enacted by the U.S. Congress in 2007 (Public Laws 110-116 and 110-181) mandates the destruction of the remaining U.S. national chemical stockpile in accordance with the April 2012 date, but in no circumstances later than Dec. 31, 2017. [3]
