Depending on the nature of the discharge, you may be required to:
- Obtain municipal or regional sewer discharge permits
- Register on the Environmental Site Activity Registry (EASR)
- Apply for an Environmental Compliance Approval (ECA)
- Secure a Permit To Take Water (PTTW) if the water originates from pumping surface water or groundwater
