40 cfr 433 passivation

It has recently come to my attention that my passivation process for SS is going to be classified as a categorical metal finisher under 40 CFR 433 and I am going to have to go through endless testing of my wastewater. Is there any way to get out of this situation..short of halting the passivation process.
