TSS and TP Removal Efficiency Evaluation Strategies
Link to this table

Pollutant Removal Assessment Strategy Description Relative effort Relative accuracy
Evaluation of MPCA stormwater pond design criteria Evaluation of pond sizing criteria against MPCA stormwater pond design standards to produce a relative evaluation of pond performance Low Low
Stormwater pond inspection/assessment Guidance related to scheduling and performing routing visual inspections and less-frequent assessments of pond sedimentation depth Medium/high NA1
Stormwater pond pollutant removal modeling Evaluation of the pollutant reduction achieved by stormwater ponds through the use of empirically-based or physically-based water quality models Low/medium Medium
Stormwater pond water quality monitoring Evaluation of the pollutant reduction achieved by stormwater ponds through direct monitoring of pollutant concentrations into and leaving the pond High High

1Stormwater pond inspection/assessment does not inherently provide an estimate of TSS/TP removal. However, inspection/assessment efforts are critical to ensuring a stormwater pond is performing as originally designed.
