Stormwater regulation, management, and control

Program or Topic Area Leader

Christe Alwin


To protect our water resources, communities, construction companies, industries, and others, use stormwater controls, known as best management practices (BMPs). These BMPs filter out pollutants and/or prevent pollution by controlling it at its source.

The National Pollutant Discharge Elimination System (NPDES) program regulates some stormwater discharges from three potential sources: municipal separate storm sewer systems (MS4s), construction activities, and industrial activities. Operators of these sources might be required to obtain an NPDES permit before they can discharge stormwater. This permitting mechanism is designed to prevent stormwater runoff from washing harmful pollutants into local surface waters.

Program Expertise

  • Human Dimensions — Water Infrastructure — Storm water engineering and management
  • Human Dimensions — Water Quality Policy and Management — Local government policy and strategies
  • Physical — Hydrologic — Restoration / BMP
  • Chemical — Water Quality (nutrients, pH, DO, etc.)

Program Focus

MDEQ’s stormwater programs are focused on BMP implementation. Michigan-specific BMP studies are desired. Areas of interest include:
• Tools to assist with BMP selection
• Measurement of BMP effectiveness, including green infrastructure, considering a range of site conditions and storm events
• Reliable rates of pollutant removal by BMP type
• Impacts from the lack of regular BMP maintenance
• Economic impacts of stormwater pollution
• Chloride impacts
