Stormwater Exceedances and Corrective Actions: Practical Response Steps
A stormwater exceedance should trigger a structured review of potential sources, site conditions, BMP performance, sampling methods, and follow-up actions. The goal is to reduce pollutant discharge and create a clear record of what was changed.
Response steps
- Review the lab result and sampling conditions.
- Check whether the sample location was representative.
- Inspect upstream drainage areas and material exposure.
- Evaluate BMP condition, maintenance, and bypass potential.
- Document corrective actions with dates and photos.
- Track whether future samples show improvement.
