The Louisiana Military Department (LMD) submitted a contractor proposal to EPA for the cleanup of M6 propellant. EPA conducted a technical review of the contractor proposal and approved it. EPA announced the technology that was selected on May 8, 2015. The technology selected is Contained Burn System (CBS). The CBS will provide superior protection to the public and the environment by processing all exhaust gases and products of combustion, and removing those emissions and materials of concern prior to release of cleaned exhaust gases to the environment.

The CBS consists of the propellant being placed in a Contained Burn Chamber (CBC) that is constructed of high quality steel and then burned at a high temperature for a long enough time to ensure complete combustion. Once the burn process cycle is completed, the burn tray will be removed from the chamber and a new tray containing another batch of M6 material will be placed into the chamber.

Residue ash will be removed from the tray after each cycle. As a result of the contained burn process, all residue ash is anticipated to be non-hazardous. Prior to shipment offsite, the ash will be sampled and profiled for proper disposal. The operation will be conducted on a twenty-four (24) hour basis to achieve the daily disposal rate required. The vendor recommends Area-I for operations due to its secluded location.

Inside the CBC, the exhaust gases will pass through filters, scrubbers and an afterburner before the clean exhaust gases are released back into the environment. Air emission will be monitored during the operation.
