What type of event should trigger a thorough BMP inspection?

A significant rain event is a crucial trigger for a thorough Best Management Practices (BMP) inspection because such events can lead to increased erosion and sediment runoff, potentially overwhelming existing BMPs. Heavy rainfall can cause runoff to exceed the design capacity of erosion control systems, leading to the failure of these measures and an increased risk of sediment discharging into water bodies. Conducting an inspection after significant rain allows inspectors to assess the effectiveness of current BMPs in real-time conditions, identify any failures or needed repairs, and make necessary adjustments to mitigate environmental impacts. This proactive approach helps to protect water quality and maintain compliance with regulatory requirements related to erosion control and sediment management.
