Frequent Questions

If electroplating wastewater is treated, rendered nonhazardous, and then stored, does sludge resulting from that nonhazardous wastewater storage carry an electroplating waste listing?

Treatment of any hazardous waste or nonhazardous electroplating wastewater within the scope of the F006 listing can generate listed F006 sludge.  That is, when the wastewater treatment sludge precipitates, whether in the treatment train or during storage, it meets the listing description for F006 regardless of its composition and constituent concentrations.(Memo, Lowrance to Greenburg; July 5, 1989 (RCRA Online #11439).
