Original proposal
Proposal details
This proposal is for an amendment to the existing Environmental Compliance Approval No. 3135- AVZRXV for Goldcorp Canada Ltd. (Newmont Porcupine) in support of management of water elevations within the open pit and renewed open pit mining at the Pamour Mine, located in the Township of Whitney, City of Timmins (District of Cochrane), Ontario.
It is proposed that site water, including surface run-off and groundwater from the open pit, be diverted to a newly constructed effluent treatment plant (ETP), and discharged via a pipeline and constructed open channel to the Porcupine River. The proposed ETP is designed to treat the water from the open pit using various steps for the precipitation of metals followed by clarification and ultrafiltration.
The treatment system will include effluent measurement/monitoring equipment and associated appurtenances, and is designed to meet provincial and federal effluent objectives prior to discharge to the Porcupine River.
