melting, casting and trimming .,perations were performed on the LX -14 explosives resulting in waste LX -14 residuals. However, there is no market for LX -14 wastes and therefore they must be managed a hazardous waste. According to state and f eral regulations, any person who treats, stores, or disposes of hazardous waste must obtain a Hazardous Waste Facility Permit approved by DTSC. Due to this requirement, Primex has applied to DTSC for a permit to al ow on-site treatment of LX -14 wastes by detc nating it in a closed vessel detonation unit. A description of this project is presented in S tion III of this fact sheet. Figu e I Site Map OG% ' 12C 205 T CY 301 5 of Fo t CGRRh� GIG PRIMES Ord rl 560 _ and TacticS stems.

Project Desci iption Primex is requesting a azardous Waste Facility Permit to allow use of an existing closed vessel detonation (CVD) unit to treat waste LX -14 explosives In support of this request, Primex submittad a Part A and B application on November, 1996, describing the design specifications and operating procedures for detonation of waste LX -14 in the CVD. March 1997 The CVD unit is ...tsically a pressure vessel (see Figure 2) constructed of carbon steel. The unit is 96 inches in diameter and 177 inches long. The vessel wall is one inch thick. It is cylindrical in shape with rounded ends and weighs 22,600 pounds and has a volume of 445 cubic feet. Vertically supported by a steel structure, the vessel has a port at each end and two ports on the sides. The end ports are used for loading the vessel and unloading ash. The top port is equipped with a vacuum vent, a high efficiency particulate air (HEPA) filter system that captures solid particles suspended in air. One side port is also equipped with a HEPA filter and the other is connected to a blower that supplies air into the tank. The basic operation of the unit is as follows: • The waste, weighing no more than 10 lbs, will be attached to a detonation device and suspended in the vessel from the top port. • The vessel will then be closed and the explosives detonated remotely from a bunker and the process monitored by a control panel from the inside of the bunker. • The gaseous by-products are then purged from the vessel and released outside through the side port with the HEPA filter. The gaseous by-products produced from the detonation of LX -14 are ammonia, hydrogen cyanide, nitrogen dioxide, carbon dioxide, carbon monoxide and water. The risk from these gases were evaluated in a health risk assessment and were found to be less than significant. The detonation also produces some particulates from the combustion of the Page 2
