Sheetflow Sampling Guidance Document

Sheetflow Sampling Guidance Document

Minnesota Pollution Control Agency

The agency’s Industrial Stormwater Multi-sector General Permit requires all permittees to conduct stormwater monitoring, including sheetflow sampling.
To do that, a facility needs to collect stormwater samples and follow a specific procedure from preparing to collect each sample through submitting the sample’s lab results to the agency. This fact sheet, and its companion video (link), offer helpful guidance and tips about how to correctly collect a sheetflow sample. Read the program’s Monitoring Guidance Manual for Minnesota’s Industrial Stormwater Multi-Sector General Permit  for comprehensive guidance about the permit’s monitoring requirements.
