Fume scrubber for small chrome plating shop

We have a small hard chrome plating operation and have been planing to install an air scrubber to comply with the chrome emissions standards. Recently we received information that suggests that hard chrome platers can achieve the emissions limits by use of fume suppressants alone. We called the company that supplies the suppressants and they could not tell us if anyone is attempting this. Does anyone know if other platers have tried this approach and were they successful with it?

I have previously discussed this and other issues with Mr. Phil Mulrine of EPA's RTP. At that time a fume suppressant that met 30 dynes /cm3 was proposed to be RACT (reasonable available control technology). This information is not current so you should check for updates. You might find more current information from :  Also, if you get flagged for "steel pickling" MACT due to electroplating you can suggest that this was not intent of CAA amendments. This has been successfully achieved with EPA previously.
