GSPCB Chairman Jose Manuel Noronha said the inspection of all the 12 jetties across the state was carried out by a team of experts, who have filed a positive report about the situation there.
Noronha said the board is "satisfied with the precautions taken by the jetty operators."
"We are satisfied with the precaution taken by the jetty operators. All of them have constructed garland drains around the pile of ore and at the end of it there is a settling pond which stops water from running into the river," he said.
Noronha said the stacks are covered by silpaulin, and there are filters to ensure that the ore does not run off in the river.
