What are the two types of industrial storm water general permits in Michigan?

In Michigan, the two types of industrial storm water general permits are appropriately identified as Storm Water from Industrial Activity and Storm Water with Required Monitoring. This classification is essential because it delineates the specific requirements and stipulations related to industrial sites that discharge storm water.

"Storm Water from Industrial Activity" pertains to permits for facilities that handle materials or conduct operations that may contribute to pollutants entering the storm water system. In contrast, "Storm Water with Required Monitoring" includes conditions necessitating regular monitoring of discharges to ensure compliance with environmental standards and to actively manage water quality.

Understanding these designations is crucial for operators, as it guides their obligations regarding storm water management and helps them maintain compliance with state regulations while protecting water quality and the environment.
