Power Plant 401-1 and 401-2 at the Indiana Army Ammunition Plant in Charlestown, Indiana were demolished in 2011-12. The two coal-fired power generating facilities had been unused since 1992 and were razed at a cost of $1.1 million by ADS Trinity. It involved scrapping 335 tons of salvageable materials from the site and the removal of the 120,000 and 145,000 square-foot structures and their associated 180-foot smokestacks.
