For six decades, the U.S. Army has safely and securely stored chemical munitions at the Pueblo Chemical Depot in Colorado. To help fulfill international treaty obligations and to meet a congressional deadline of 2023 for the elimination of these aging weapons, initial destruction of the Pueblo chemical weapons stockpile began in 2015. A utility energy service contract (UESC) executed in 2016 between the U.S. Army Corps of Engineers and the Depot’s serving utility, Black Hills Energy (BHE), directly supported this mission with the installation of a new electrical substation that was essential to the Depot’s need for uninterrupted power.
