Assessment and Maintenance of Stormwater Treatment Practices

Assessment of Stormwater BMPs Manual (pdf, 15.88 MB)

The University of Minnesota (U of M), through contract with the Minnesota Pollution Control Agency (MPCA), has developed a manual that outlines and explains proper methodology for the assessment of stormwater best management practices (BMPs). The manual promotes the "Four Levels of Assessment" which increase in difficulty and cost from 1 to 4:

1. Visual Inspection
2. Capacity Testing
3. Synthetic Runoff Testing
4. Monitoring

In the Assessment Manual, existing stormwater BMPs are organized into categories according to the process by which pollutants are removed from stormwater runoff: Filtration Practices, Infiltration Practices, Sedimentation Practices, and Biologically Enhanced Practices. The manual also includes chapters on Water Budget Measurement, Sampling, Sample Analysis, Source Reduction, and Data Analysis.
