Small MS4 Storm Water Permit

• Grand Forks City Council Presentation
• February 2, 2004
• Abbie Krebsbach
• ND Dept. of Health
• Division of Water Quality

Storm Water Impacts

• Storm water runoff from urban areas is the number
  one cause of environmental degradation of the
  nations rivers and streams, and the third
  leading cause of environmental degradation in the
  nations lakes.
• Sediment runoff rates from construction sites are
  typically 1,000 to 2,000 times greater than from
  prairie lands.

3
Storm Water Impacts

• The storm water pollution problem is twofold
• Increased volume and rate of runoff
• Increased concentration of pollutants in the
  runoff Pollutants include pesticides,
  fertilizers, construction chemicals, solvents,
  acids, oils, sediment, and debris.

• Storm water pollution can result in fish kills,
  destruction of wildlife habitat, increased
  flooding, sedimentation, contamination of
  waterways, loss of drinking water storage
  capacity, and erosion.

Benefits of Storm Water Management

• Water Quality Benefits
• Remove pollutants from storm water/snow melt
  runoff
• Provide flood control
• Reduce downstream erosion
• Promote ground water recharge
• Economic Benefits
• Avoid human health problems
• Save medical costs
• Sustain or increase recreation and swimming
  resources
• Sustain or increase wildlife habitat
