The Newport Chemical Depot, previously known as the Wabash River Ordnance Works and the Newport Army Ammunition Plant, was a 6,990-acre (28.3 km2) bulk chemical storage and destruction facility that was operated by the United States Army. It is located near Newport, in west central Indiana, thirty-two miles north of Terre Haute. The site was used as a production site for the solid explosives trinitrotoluene and RDX, as well as for heavy water. It also served as the production site for all of the U.S. military's nerve agent VX, when it was in use. All VX nerve agent at the site was neutralized by August 8, 2008. It was the third of the Army's nine chemical depots to completely destroy its stockpile.
