How long does the local authority have to review any modifications to the SWPPP?

The local authority is required to review any modifications to the Storm Water Pollution Prevention Plan (SWPPP) within a timeframe of 60 days. This period is set to ensure that changes to the SWPPP are assessed in a timely manner, enabling the local authority to evaluate the modifications for compliance with stormwater management regulations and to determine if any new risks are introduced to water quality. A 60-day review period allows for due diligence without unnecessary delays in the implementation of necessary modifications that may affect project timelines.

This timeframe establishes a balance between thorough consideration of changes and the operational needs of projects subject to stormwater management requirements. It promotes accountability and effective communication between the project developers and the local authority, fostering better management of stormwater and protection of local aquatic ecosystems.
