At least 61 active burn and denotation sites currently operate in the U.S. Most are run directly by the Department of Defense or its contractors, and do not publicly report what they burn. ProPublica obtained the delivery manifests for the only burn site that is commercially licensed and allowed to accept explosives from off-site, run by a company called Clean Harbors in Colfax, Louisiana.

In 2015, the site received more than 1.7 million pounds of hazardous explosives waste from across the country — from the U.S. military as well as from commercial users like Disney, which sends unexploded fireworks to the facility to be destroyed. Here’s what the facility burned or detonated that year. Related story.
