MARGAO: A day after directions were issued to the South Goa district Collector to seal the premises in plot Nos L-2 and L-3 in the Cuncolim Industrial Estate, the Goa State pollution Control Board (GSPCB) is mulling criminal proceedings against the occupants for allegedly handling hazardous wastes dumped on the plots.

The GSPCB on Tuesday dispatched messengers to serve the directions to the District Collector and the IDC field officer to initiate action at the ground level to ensure a total stop to waste handling in the two plots.
