Proposal details
This proposal is for new Environmental Compliance Approval for industrial sewage works for Ontario Power Generation Inc., located at 1 Holt Road South in the community of Bowmanville in the Municipality of Clarington, Ontario.
This application is for the proposed condenser cooling water (CCW) system, including a new intake to supply raw water and an outfall for discharging thermal effluent to Lake Ontario. The system is part of the Darlington New Nuclear Project, which incorporates Small Modular Reactor (SMR) technology to increase power generation capacity.
The ministry may require monitoring of the industrial wastewater effluent discharge leaving the site.
