MECP - Wastewater/Sewage Works

Existing

Implemented

Since May 2015, the Ministry has been screening environmental compliance approval (ECA) applications to determine if the activity is located in an area where the activity could be a significant drinking water threat. This is called the “primary screening”. Based on a set of criteria, an ECA application is flagged for a more detailed ‘secondary screening’ to determine if the activity associated with the application is a significant drinking water threat.
