When must the stormwater Notice of Intent (NOI) be submitted?

• A. After the SWPPP is prepared and before starting construction
• B. Before the SWPPP is prepared
• C. Only after construction has begun
• D. At the end of the construction

Answer: (A)

The stormwater Notice of Intent (NOI) must be submitted after the Stormwater Pollution Prevention Plan (SWPPP) is prepared but before construction begins. This sequence is important because the NOI acts as a notification to the appropriate regulatory authority that a project will be starting and that measures to prevent stormwater pollution will be implemented. Submitting the NOI after the SWPPP is complete ensures that the plans for managing stormwater are fully developed and in compliance with regulatory requirements before any physical construction activities commence. This helps to ensure the protection of water resources from potential pollutants associated with construction activities.
