Proposal details
This proposal is for an amendment to Environmental Compliance Approval No. 4428-9W4KZK for industrial sewage treatment works serving St. Clair Management Corporation, as general partner for and on behalf of St. Clair Power, L.P. located at 790 Petrolia Line, in Corunna, Ontario.
The amendment to the industrial sewage treatment works include modifications to the containment structures associated with the existing generator step-up transformers to accommodate full oil volumes. The updated works are designed to meet primary treatment requirements prior to discharge into the St. Clair River via an outfall located at the nearby Nova Chemicals Corunna site.
The Ministry may require monitoring of the industrial wastewater effluent discharge leaving the site
