SWPPP vs Stormwater Monitoring Plan: What Is the Difference?
A SWPPP explains how a facility manages stormwater pollution risk. A monitoring plan explains how the facility will inspect, sample, observe, and document stormwater conditions. The two documents should support each other.
SWPPP focus
- Industrial activities and pollutant sources.
- Drainage areas and discharge points.
- BMPs, housekeeping, maintenance, and training.
- Spill response and corrective actions.
Monitoring plan focus
- Sampling locations and parameters.
- Rainfall triggers and monitoring frequency.
- Visual observations and field measurements.
- Lab coordination, chain of custody, and recordkeeping.
