This means that you don't have to meet the federal silver = limit=20 until the wastewater is mixed together & being discharged, the = significance=20 of the legal *dilution* with non-silver bearing wastewater obviously=20 depending on the volume of your other rinses. Obviously if your=20 film/artwork site is in a separate facility or you drain wastewater from = there separately from your plating area this doesn't apply. I'm not putting down waste minimization, far from it. There are many = cost &=20 regulatory benefits to waste minimization in addition to my narrow focus = of=20 pollutants to the sewer. I put in my two cents worth since previous = posts=20 seemed unclear on where federal silver limits would be applied, which = may=20 affect the business decision of what to spend on silver treatment.
