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.
