|Testing Nickel Emissions From Metal Finishing Operations (Phase 2), Final Report (823 pp, 48 MB)
Nickel emissions from electroplating operations are of concern to EPA. So to better manage the environmental challenges that result from wastes generated by nickel plating, EPA obtained nickel emission data from nickel plating operations using EPA Methods 29 and 306A.
For this project, five nickel plating processes were tested:
By modifying some of the operating parameters (such as surface tension and agitation methods), EPA can determine the impact of these operational changes on nickel emissions.
The stack testing was conducted over two years, from June 2004 through January 2006. Following are conclusions based on the stack testing results:
The results of the study indicate that EPA Methods 29 and 306A provide similar results when measuring nickel emissions from the electroless nickel, watts nickel, and wood’s nickel strike processes. However, further testing is needed on a controlled process or conducted simultaneously to determine whether Method 306A is an acceptable alternative to Method 29 for measuring nickel emissions from nickel plating processes in general.
