Report: 6 million pounds of gunpowder improperly stored in Louisiana December 3, 2012 -- Updated 1039 GMT (1839 HKT) KSLA: The town of Doyline, Louisiana, remains evacuated The gunpowder was found during an investigation after an October 15 blast Police personnel and company employees are trying to safely remove the stockpile (CNN) -- A massive stockpile of at least 6 million pounds of gunpowder was found improperly stored in Louisiana's Camp Minden, not far from where an explosion occurred two months ago, authorities said. A weekend operation to remove the stockpile will likely extend until Tuesday, CNN affiliate KSLA reported. The town of Doyline, population 820, remains evacuated. Louisiana State Police said the M6 smokeless gunpowder was found during a follow-up inspection after an October 15 blast at Explo Systems, Inc. The explosive materials were found "in the open and in other unapproved locations," police said. Authorities initially estimated a stockpile of 1 million pounds of gunpowder before police personnel and Explo employees began moving the supply. "The Louisiana National Guard has been instrumental in making available additional magazine storage space for the propellant," Louisiana State Police said. According to Explo's website, the company has been demilitarizing and recovering explosives and propellant for more than 15 years. Camp Minden is home to a Louisiana National Guard training site.
