When must an application for reissuance of industrial storm water permit coverage be submitted in MiWaters?

The requirement to submit an application for reissuance of industrial storm water permit coverage 6 months prior to expiration is rooted in the regulations governing environmental permits. This timeline ensures that there is adequate time for the reviewing authorities to assess the application, consider any necessary updates to the facility's stormwater management practices, and make decisions regarding the continuation of the permit.

By allowing 6 months, it provides both the applicant and the regulatory agency ample time to address potential issues, including any needed adjustments to the stormwater pollution prevention plan (SWPPP) or compliance with updated regulations. This proactive measure minimizes the risk of permitting lapses and ensures ongoing compliance with environmental standards.

Submitting earlier than this time frame, such as 3, 9, or 12 months prior to expiration, may not align with the established regulatory processes or could result in unnecessary delays or complications. The 6-month window strikes a suitable balance between ensuring thorough scrutiny of applications and preventing interruptions in permit coverage.
