Other Environmental Practices: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - CSL Operating LLC has been making efforts to reduce waste for over 20 years and has been successful. Therefore, what pollution prevention that has been identified, has been done, or at least tried.This year we have implemented some additional treatment activities which actually do reduce the amount of waste being sent off-site but is not true source reduction. Barriers include space limitations, concern for product quality, stringent cleaning requirements, and customer specifications. Other Environmental Practices: Waste Treatment - Ultra Violet light was implemented to kill bacteria and break down chelators more cleanly.The silver-plating process was changed to non-cyanide-based.Processes with chromium were changed from hexavalent chromium to trivalent chromium.Spent alkaline cleaners are used to neutralize spent acid, rather than new caustic material. Microbes may be used to "eat" some of the waste. |

Source Reduction - CSL implemented an Electroless Nickel Evaporator Unit in 2010.This unit was designed to reduce the amount of chemicals used to precipitate the metals and neutralize the electroless nickel plating solution. The evaporator concentrate would then be sent off-site for metals recovery and the amount of metal hydroxide treatment sludge from the in-house system would be reduced.The solution is removed from the plating bath and rather than being sent directly to the in-house waste water treatment system, the solution is put into the evaporator unit. The solution is evaporated to a third of its original volume.
Other Barriers to Source Reduction - 5. Specific regulatory/permit burdensCSL implemented source reduction measures, however, actual measurable reduction was not achieved due to stringent requirements of NADCAP. CSL had to maintain tight process control which included more frequent process bath, rinse and filter changes generating more waste. |
