D. Provide cos cost basis for P2 measures evaluated but not implemented andreason(s) why they were not implemented:

1 Pollution prevention means any pmctice that reduces or eliminates the creation ofpollutants through increased efficiency in the use ofraw materials, energy, water, orotherresources. Examples include SUbstituting a hazardous material with a non-hazardous material, ora process change that eliminates the use ofa hazardous material. 2 Dragoutrefers to residual plating orfmishing bath solution that remains onparts orworkpieces after they are**~oved** from the tank.
