How often must a no exposure certification be submitted in MiWaters for regulated industrial facilities without exposure of industrial materials?

The requirement for submitting a no exposure certification in MiWaters for regulated industrial facilities is established to ensure that facilities effectively manage their stormwater impacts. The correct timeframe for submission is every five years. This frequency allows facilities to demonstrate their ongoing compliance with the no exposure condition, which means that there are no industrial materials or activities exposed to rain, snow, or runoff.

This five-year interval strikes a balance between monitoring and operational capability, allowing for necessary changes in facility conditions, practices, or regulations to be acknowledged and addressed. Submitting a new certification every five years provides regulatory agencies a means to ensure that facilities maintain their no exposure status and continue to protect water quality effectively.

In comparison, shorter intervals would create an unnecessary administrative burden on businesses, while longer intervals could lead to outdated information and potential risks to stormwater management. Thus, every five years is the appropriate requirement for these certifications.
