"The California Department of Toxic Substances Control has sued Ernest and Julio Gallo's glass production plant in Modesto. Keith Kihara with the state says the company improperly stored, then improperly recycled oil and hazardous dust -containing lead, arsenic, cadmium and selenium from 2009 -to- last year.

'What Gallo was doing was getting this dust that was collected by the air pollution control device and re-introducing it as an ingredient in the glass-making process.'

The suit alleges Gallo broke the law by recycling the dust."
