There are several processes which are exempt from the
P006 listing, one of which is fine plating (aegregated baaie)
on carbon steel. Since the Agency's current definition of >'-
electroplating includes phoaphatJCa^rocaaaes, the exemption
for sine plating on carbon steel['*mti&.'applies ,to; sine,;- ',v.;-,'. ;w^':"
phosphating on carbon ateal. This exemption applies only
<«• if the wastestream from the sine phosphating process is not
^ comingled with any other hasardoua waate. If the wastestream
2 that you are describing is sine phosphating on earboft steel
x: and is segregated - i.e., it is not. eomingled^with wastewaters
.* from any other processes that contain hazardous constituents,
.2 then the Agency considers the waate to be exempt from BPA*a
