Ontario committed to the management of persistent toxic substance with the signing of the 1987 Canada/Ontario Agreement Respecting the Great Lakes Basin Ecosystem (COA). Since then the COA has been revised and renewed several times.

The Municipal Industrial Strategy for Abatement (MISA) program was the provincial response to address levels of persistent toxic substances in industrial direct discharges entering Ontario’s waterways, in recent years the legislation has been renamed to Effluent Monitoring Effluent Limit (EMEL).

The EMEL (formerly MISA) regulations are nine sector-specific regulations that set limits on toxic pollutants in wastewater discharged directly into a body of water by a designated industrial facility. The regulation sets different discharge limits for specific facilities within each sector. Each parameter regulated under the program is regulated with both a daily limit and a monthly average limit and requires the effluent not to be toxic to fish.. One of the sectors is the electric power generation sector under which Bruce Power is regulated.

The program’s aim remains the same and that is to reduce the discharges of toxic contaminants to Ontario’s waters and ultimately to eliminate persistent toxic contaminants from all discharges. Bruce Power’s Environmental Policy makes a commitment to not only comply with regulations but is also in alignment with the intent and the goals of the program. Bruce Power’s Environmental Policy goes further to describe the company’s view on environmental protection.

Each station and associated facility within Bruce Power must sample its own wastewater discharges and have them tested to MOECC specifications. In addition, each year Bruce Power is required to prepare an Effluent Monitoring Effluent Limit (EMEL) Report for the Ministry of the Environment relating to the previous calendar year that includes:

  • A summary of concentrations
  • A summary of plant loadings
  • A summary of the results of monitoring
  • A summary of volumes
  • A summary of the concentrations or other results that exceed a limit
  • A summary of the incidents in which effluent that would normally flow past a effluent sampling point is discharged from the discharger’s plant without flowing past that sampling point
