What should be done with the SWPPP during a significant storm?

Conducting an inspection to assess the effectiveness of the Best Management Practices (BMPs) during a significant storm is crucial for maintaining compliance with stormwater regulations and ensuring environmental protection. This action allows the team to evaluate how well the BMPs are functioning under adverse weather conditions, determine if they're preventing pollution as intended, and identify any necessary adjustments or repairs.

Observing the BMPs in action during heavy rainfall provides valuable insights into their performance and helps ensure that they can handle the stormwater effectively. By regularly inspecting these practices, the team can respond proactively to any issues that may arise, thus maintaining the integrity of the stormwater management system.

The other choices have their importance but don't directly address the immediate need to evaluate BMP functionality during a storm. Updating the plan or notifying authorities may be necessary actions tied to overall stormwater management, but they are not immediate responses needed during the actual event. Similarly, canceling construction activities is a significant measure that could be based on assessments, but it comes after evaluating current conditions and BMP effectiveness.
