of the Environmental Protection Act, generators of liquid industrial and hazardous waste are required to annually register their waste generation facilities with the Ministry. The deadline for 2016 registration is February 15, 2016.
In order for an individual to complete the 2016 registration renewal for their organization, that individual must have HWIN administrator rights.
When you log in, HWIN will check to see if you have administrator rights. If you have administrator rights (and your organization has not previously completed registration renewal), you will be asked if you want to complete the 2016 registration renewal now or if you want to wait. If you choose to wait, you will be directed to My HWIN. If you choose to renew, HWIN will take you through the registration renewal process. If you do not have administrator rights, you will be directed to My HWIN when you log in.
