Metal munition parts are washed with dilute nitric acid and sent to a metal parts treater along with undissolved fuzes. Any agent remaining on the metal parts and the fuzes is destroyed by thermal decomposition. The resultant metal parts are decontaminated to a 5X level. 

Decontamination of metal parts and fuzes to a 5X condition in the metal parts treater (MPT). 

Finding 2-1. Continued recycling of the particulates into the metal parts treater from the cyclone particulate separator of the metal parts treater offgas treatment system may cause solids buildup, which could impede operation of the metal parts treater. 

Recommendation 2-1. The operation of the metal parts treater should be modified to avoid solids buildup and the attendant creation of a particulate waste stream that could impede its operation.

Metal parts are all treated either in the batch metal parts treater (batch MPT) or the rotary metal parts treater (rotary MPT) to decontaminate metal parts to 5X. 

Finding (Pueblo) PH-3. The Parsons/Honeywell WHEAT munitions disassembly machine and the projectile rotary washout machine have not been tested to demonstrate reliable removal of solidified agent to levels sufficiently low for treatment in the metal parts treaters. Testing planned for 2001 may provide data to verify that these machines will be reliable enough to achieve target throughput rates. 

Finding (Pueblo) PH-4. Leaks into or out of the batch metal parts treater, rotary metal parts treater, and continuous steam treater were adequately addressed in the preliminary hazards analysis. 

Finding (Pueblo) PH-5. The rotary metal parts treater has not been tested the concept, therefore, remains to be demonstrated. 

Finding (Pueblo) PH-9. Although the catalytic oxidation units have generally performed well in destroying volatile organic compounds, it has not yet been demonstrated that they can reduce pollutants in the vent gases from the continuous steam treater or metal parts treater to acceptable levels.
