During a routine inspection, if a non-storm water discharge is observed, what must be prepared?

• A. A non-storm water report.
• B. A stormwater pollution prevention plan update.
• C. A water quality report.
• D. A discharge permit renewal.

Answer: (A)

When a non-storm water discharge is observed, the key requirement is to document and report the event. Preparing a non-storm water discharge report creates an auditable record of the incident, including when and where the discharge occurred, the source, approximate volume, any potential pollutants, the immediate containment or cleanup actions taken, and plans to prevent recurrence. This reporting helps ensure regulatory transparency and supports follow-up corrective actions within the stormwater program.

The other options don’t fit the immediate need because updating the stormwater pollution prevention plan is about changes to controls or BMPs, not documenting a single observed discharge; a water quality report covers general water quality over a period rather than a specific incident; and a discharge permit renewal is a periodic requirement, not an incident-triggered document.
