Grinding Dust

Dust or grit from grinding operations can be hazardous depending on the material being ground and on cutting oils or coolants used. For example, jewelry and art glass grinding can contain heavy metals, seam fillers can contain lead, and rock dusts or slurries may have harmful particulates, high pH and turbidity. Do not dispose of slurries in the sanitary sewer or septic systems. To dispose of slurries or grinding dust in the landfill, you may need a waste clearance.
