Other Barriers to Source Reduction - Nitric acid dip tank chemistry was fully emptied and recharged in April 2017. This process-related activity correlated to a significant increase in the generation of passivating process/dip tank-related wastestreams (e.g., waste nitric acid solution) in 2017. These wastestreams are generated rather infrequently and usually occur only when the nitric acid dip tank chemistry is fully emptied and recharged. This process last occurred in late 2011, and the wastes generated from it were managed in early 2012. Therefore, similar waste should be generated less frequently in future years until the next nitric dip tank chemistry changeout. |

Other Barriers to Source Reduction - Nitric acid dip tank chemistry was fully emptied and recharged in late 2011. This activity correlated to a significant increase in treatment sludge generation. Additionally, this process-related activity correlated to the generation of additional passivating process/dip tank-related wastestreams in 2011. These wastestreams are generated rather infrequently and usually occur only when the nitric acid dip tank chemistry is fully emptied and recharged. These processes did not occur in 2012. Subsequently, wastes managed in 2012 as a result of these processes decreased significantly. |
