Excess energetic material that is no longer needed for further testing and evaluation is <br /> mainly treated at LLNL's Explosive Waste Treatment Facility (EWTF). To accommodate <br /> need for additional material storage at Site 300, a concerted effort was made to reduce the <br /> current stored inventory in 2018. However, this reduction effort to remove the excess <br /> energetic material would have affected the permitted treatment capacity at EWTF, including <br /> its ability to treat other energetic waste that cannot be shipped off-site. Therefore, the excess <br /> energetic material (that can be shipped off-site)was consolidated at Mag 38 for off-site <br /> disposal. <br /> SOURCE REDUCTION/POLLUTION PREVENTION EVALUATION <br /> Description of Measure: <br /> LLNL plans to continue existing best management practices to minimize this infrequent <br /> waste stream. No other source reduction/pollution prevention measures are planned. <br /> September 1, 2019 SB 14 Plan III-12 <br /> ESH-EFA-P2S-19-16592 <br />
