The correct timeframe for reporting Category 1 Sanitary Sewer Overflows (SSOs) that discharge to a drainage channel and/or surface water is within 2 hours. This urgency is based on the potential public health and environmental risks associated with such discharges.

Category 1 SSOs are those that can significantly impact public safety and the environment due to their volume and proximity to sensitive areas. The 2-hour reporting requirement facilitates a swift response to mitigate potential negative effects, allowing both regulatory authorities and the community to take necessary precautions and actions promptly.

This requirement ensures that authorities are notified quickly, allowing for immediate assessment and response to minimize harm. Understanding the specific reporting timelines for various categories of SSOs is crucial for compliance with regulations and for the protection of public health and the environment.
