Mining operations in Sonshi have been suspended since April 28 after these mine lease holders were found to be involved in violation of environmental norms.
Also, the GSPCB has kept on hold the renewal of leases of these mines under the Air and Water Pollution (control) Act, following protests by locals complaining about severe air pollution in the village.
The next meeting is scheduled tomorrow.
"If the mining firms fail to furnish the bank guarantee in the meeting scheduled tomorrow, they will not be allowed to operate (this season)," a senior GSPCB official told PTI.

"Since the mining season ends on May 31, we will have to then take up their matter only after monsoon when the new season begins," he added.
The official said the guarantee amount will be based on the area of the lease.
"If lease holder fails to control the air and water pollution in the vicinity, the bank guarantee will be forfeited by the Board," he said.
Meanwhile, Goa Mineral Ore Exporters Association (GMOEA) has rubbished media reports that air quality monitoring equipment have been manipulated by the mining companies.
"As an industry body we wish to clarify that all the equipment used by the mining companies are compliant and strictly meet the guidelines as mentioned by the various regulatory authorities," GMOEA said in a press note here.
